Supervision and Regulation
General
S&T and S&T Bank are eachis extensively regulated under federal and state law. Regulation of bank holding companies and banks is intended primarily for the protection of consumers, depositors, borrowers, the Federal Deposit Insurance Fund, or DIF, and the banking system as a whole, and not for the protection of shareholders or creditors. The following describes certain aspects of that regulation and does not purport to be a complete description of all regulations that affect S&T and S&T Bank or all aspects of any regulation discussed here.

Table of Contents To the extent statutory or regulatory provisions are described, the description is qualified in its entirety by reference to the particular statutory or regulatory provisions.

Item 1.  BUSINESS -- continued




ToThe Dodd-Frank Wall Street Reform and Consumer Protection Act, or Dodd-Frank Act, enacted in July 2010, has had and will continue to have a broad impact on the extent statutory orfinancial services industry, including significant regulatory provisions are described, the description is qualified in its entirety by referenceand compliance changes addressing, among other things: (i) enhanced resolution authority of troubled and failing banks and their holding companies; (ii) increased capital and liquidity requirements; (iii) increased regulatory examination fees; (iv) changes to assessments to be paid to the particularFDIC for federal deposit insurance; (v) enhanced corporate governance and executive compensation requirements and disclosures; and (vi) numerous other provisions designed to improve supervision and oversight of, and strengthen safety and soundness for, the financial services sector. Additionally, the Dodd-Frank Act established a new framework for systemic risk oversight within the financial system to be distributed among new and existing federal regulatory agencies, including the Financial Stability Oversight Council, the Federal Reserve Board, the Office of the Comptroller of the Currency and the FDIC. While certain requirements called for in the Dodd-Frank Act have been implemented, these regulations are subject to continuing interpretation and potential amendment, and a variety of the requirements remain to be implemented. Given the continued uncertainty associated with the ongoing implementation of the requirements of Dodd-Frank Act by the various regulatory agencies, including the manner in which the remaining provisions will be implemented and the interpretation of and potential amendments to existing regulations, the full extent of the impact of such requirements on financial institutions’ operations is unclear. The continuing changes resulting from the Dodd-Frank Act may impact the profitability of our business activities, require changes to certain of our business practices, increase our operating and compliance costs, or otherwise adversely affect our business. These changes may also require us to invest significant management attention and resources to evaluate and make necessary changes in order to comply with new statutory orand regulatory provisions. Proposalsrequirements.
In addition, proposals to change the laws and regulations governing the banking industry are frequently raised in Congress, in state legislatures and before the various bank regulatory agencies.agencies that may impact S&T. Such initiatives to change the laws and regulations may include proposals to expand or contract the powers of bank holding companies and depository institutions or proposals to substantially change the financial institution regulatory system. Any such legislation could change bank statutes and our operating environment in substantial and unpredictable ways. If enacted, such legislation could affect how S&T and S&T Bank operate and could significantly increase costs, impede the efficiency of internal business processes, limit our ability to pursue business opportunities in an efficient manner, or affect the competitive balance among banks, credit unions and other financial institutions, any of which could materially and adversely affect our business, financial condition and results of operations. The likelihood and timing of any changes and the impact such changes might have on S&T or S&T Bank is impossible to determine with any certainty.
Any change in applicable laws or regulations, or in the way such laws or regulations are interpreted by regulatory agencies or courts, may have a material impact on our business, operations and earnings.
S&T
We are a bank holding company subject to regulation under the BHCA and the examination and reporting requirements of the Federal Reserve Board. Under the BHCA, a bank holding company may not directly or indirectly acquire ownership or control of more than five percent of the voting shares or substantially all of the assets of any additional bank, or merge or consolidate with another bank holding company, without the prior approval of the Federal Reserve Board. We have maintained a passive ownership position in Allegheny Valley Bancorp, Inc. (14.2 percent) pursuant to approval from the Federal Reserve Board.
As a bank holding company, we are expected under statutory and regulatory provisions to serve as a source of financial and managerial strength to our subsidiary bank. A bank holding company is also expected to commit resources, including capital and other funds, to support its subsidiary bank.
We elected to become a financial holding company under the BHCA in 2001 and thereby may engage in a broader range of financial activities than are permissible for traditional bank holding companies. In order to maintain our status as a financial holding company, we must remain “well-capitalized” and “well-managed” and the depository institutions controlled by us must remain “well-capitalized,” “well-managed” (as defined in federal law) and have at least a “satisfactory” Community Reinvestment Act, or CRA, rating. Refer to Note 24 Regulatory Matters to the Consolidated Financial Statements contained in Part II, Item 8 Note 24 Regulatory Matters, of this Report for information concerning the current capital ratios of S&T and S&T Bank. No prior regulatory approval is required for a financial holding company with total consolidated assets less than $50 billion to acquire a company, other than a bank or savings association, engaged in activities that are financial in nature or incidental to activities that are financial in nature, as determined by the Federal Reserve Board, unless the total consolidated assets to be acquired exceed $10 billion. The BHCA identifies several activities as “financial in nature” including, among others, securities underwriting; dealing and market making; sponsoring mutual funds and investment companies; insurance underwriting and sales agency; investment advisory activities; merchant banking activities and activities that the Federal Reserve Board has determined to be closely related to banking. Banks may also engage in, subject to limitations on investment, activities that are financial in nature, other than insurance underwriting, insurance company portfolio investment, real estate development and real estate investment, through a financial subsidiary of the bank, if the bank is “well-capitalized,” “well-managed” and has at least a “satisfactory” CRA rating.
If S&T or S&T Bank ceases to be “well-capitalized” or “well-managed,” we will not be in compliance with the requirements of the BHCA regarding financial holding companies or requirements regarding the operation of financial subsidiaries by insured banks.

Item 1.  BUSINESS -- continued




If a financial holding company is notified by the Federal Reserve Board of such a change in the ratings of any of its subsidiary banks, it must take certain corrective actions within specified time frames. Furthermore, if S&T Bank was to receive a CRA rating of less than “satisfactory,” then we would be prohibited from engaging in certain new activities or acquiring companies engaged in certain financial activities until the rating is raised to “satisfactory” or better.
We are presently engaged in nonbanking activities through the following five entities:
9th
9th Street Holdings, Inc. was formed in June 1988 to hold and manage a group of investments previously owned by S&T Bank and to give us additional latitude to purchase other investments.
S&T Bancholdings, Inc. was formed in August 2002 to hold and manage a group of investments previously owned by S&T Bank and to give us additional latitude to purchase other investments.
CTCLIC is a joint venture with another financial institution, actingand acts as a reinsurer of credit life, accident and health insurance policies that were sold by S&T Bank and the other institution. S&T Bank and the other institution each have ownership interests of 50 percent in CTCLIC.
S&T Insurance Group, LLC distributes life insurance and long-term disability income insurance products. During 2001, S&T Insurance Group, LLC and Attorneys Abstract Company, Inc. entered into an agreement to form S&T Settlement Services, LLC, or STSS, with respective ownership interests of 55 percent and 45 percent. STSS is a title insurance agency servicing commercial customers. During 2002, S&T Insurance Group, LLC expanded into the property and casualty insurance business with the acquisition of S&T-Evergreen Insurance, LLC. On January 1, 2018 we sold a 70 percent majority interest in the assets of our subsidiary, S&T-Evergreen Insurance, LLC. We transferred our remaining 30 percent share of net assets from S&T Evergreen Insurance, LLC to a new entity for a 30 percent partnership interest in a new insurance entity.
Stewart Capital Advisors, LLC was formed in August 2005 and is a registered investment advisor that manages private investment accounts for individuals and institutions and advises the Stewart Capital Mid Cap Fund.institutions.

S&T Bank
As a Pennsylvania-chartered, FDIC-insured non-member commercial bank, S&T Bank is subject to the supervision and regulation of the Pennsylvania Department of Banking and Securities, or PADBS, and the FDIC. We are also subject to various requirements and restrictions under federal and state law, including requirements to maintain reserves against deposits, restrictions on the types, amount and terms and conditions of loans that may be granted and limits on the types of other activities in which S&T Bank may engage and the investments it may make.
In addition, pursuant to the federal Bank Merger Act, S&T Bank must obtain the prior approval of the FDIC before it can merge or consolidate with, or acquire the assets or assume the deposit liabilities of another bank.
S&T Bank is subject to affiliate transaction rules in Sections 23A and 23B of the Federal Reserve Act as implemented by the Federal Reserve'sReserve Board's Regulation W, that limit the amount of transactions between itself and S&T or any other company or entity that controls or is under common control with any company or entity that controls S&T’s nonbank subsidiaries.&T Bank, including for most purposes any financial or depository institution subsidiary of S&T Bank. Under these provisions, “covered” transactions, including making loans, purchasing assets, issuing guarantees and other similar transactions, between a bank and its parent company or any single nonbankother affiliate, generally are limited to 10 percent of the bank subsidiary’s capital and surplus, and with respect to all transactions with affiliates, are limited to 20 percent of the bank subsidiary’s capital and surplus. Loans and extensions of credit from a bank to an affiliate generally are required to be secured by eligible collateral in specified amounts.amounts, and in general all affiliated transactions must be on terms consistent with safe and sound banking practices. The Dodd-Frank Act Wall Street Reform and Consumer Protection Act, or Dodd-Frank Act, expandsexpanded the affiliate transaction rules to broaden the definition of affiliate and to apply toinclude as covered transactions securities borrowing or lending, repurchase or reverse repurchase agreements and derivatives activities, that we may have with an affiliate, as well asand to strengthen collateral requirements and limit Federal Reserve exemptive authority. Also,
Federal law also constrains the definitiontypes and amounts of “extension of credit” for transactions withloans that S&T Bank may make to its executive officers, directors and principal shareholders wasshareholders. Among other things, these loans are limited in amount, must be approved by the bank’s board of directors in advance, and must be on terms and conditions as favorable to the bank as those available to an unrelated person. The Dodd-Frank Act strengthened restrictions on loans to insiders and expanded the types of transactions subject to the various limits to include credit exposure arising from a derivative transaction, a repurchase or reverse repurchase agreement and a securities lending or borrowing transaction. These expansions became effective July 21, 2012. These provisions have not had a material effectThe Dodd-Frank Act also placed restrictions on S&T or S&T Bank.certain asset sales to and from an insider to an institution, including requirements that such sales be on market terms and, in certain circumstances, approved by the institution’s board of directors.
Insurance of Accounts; Depositor Preference
The deposits of S&T Bank are insured up to applicable limits per insured depositor by the Deposit Insurance Fund, or DIF, as administered by the FDIC. The Dodd-Frank Act codified FDIC deposit insurance coverage per separately insured depositor for all account types at $250,000.

Item 1.  BUSINESS -- continued




As an FDIC-insured bank, S&T Bank is subject to FDIC insurance assessments, which are imposed based upon the calculated risk the institution poses to the Deposit Insurance Fund, or DIF. Under thisIn July 2016, the FDIC Board of Directors adopted a revised final rule to refine the deposit insurance assessment system for small insured depository institutions (less than $10 billion in assets) that have been federally insured for at least five years by: revising the financial ratios method for determining assessment rates so that it is based on a statistical model estimating the probability of failure over three years; updating the financial measures used in the financial ratios method consistent with the statistical model; and eliminating risk is definedcategories for established small banks and measured using the financial ratios method to determine assessment rates for all such banks. The amended FDIC insurance assessment benefits many small institutions with a lower rate; we, however, have incurred a minimal increase to our base rate.
Under the current assessment system, for an institution’s supervisory ratingsinstitution with other risk measures, includingless than $10 billion in assets, assessment rates are determined based on a combination of financial ratios.ratios and CAMELS composite ratings. The assessment rate schedule can change from time to time, at the discretion of the FDIC, subject to certain limits. Under the current system, premiums are assessed quarterly. Assessments are calculated as a percentage of average consolidated total assets less average tangible equity during the assessment period. The current total base assessment rates on an annualized basis range from 2.51.5 basis points for certain “well-capitalized,” “well-managed” banks, with the highest ratings, to 4540 basis points for complex institutions posing the most risk to the DIF. The FDIC may raise or lower these assessment rates on a quarterly basis based on various factors designed to achieve a minimum designated reserve ratio of the DIF, which the Dodd-Frank Act has mandated to be no less than 1.35 percent of estimated insured deposits.
In February 2011, the FDIC Board of Directors adopted a final rule, Deposit Insurance Assessment Base, Assessment Rate Adjustments, Dividends, Assessment Rates and Large Bank Pricing Methodology. This final rule redefined the deposit insurance assessment base to equal average consolidated total assets minus average tangible equity as requireddeposits, subsequently set at two percent by the Dodd-Frank Act, altered assessment rates, implemented the Dodd-Frank Act’s DIF dividend provisions and revised the risk-based assessment system for all large insured depository institutions (those with at least $10.0 billion in total assets). Many of the changes were made as a result of provisions of the Dodd-Frank Act that were intended to shift more of the cost of raising the reserve ratio from institutions with less than $10.0 billion in assets (such as S&T Bank) to the larger banks. Except for the future assessment rate schedules, all changes went into effect April 1, 2011 and has resulted in lower FDIC expense. FDIC.
In addition to DIF assessments, the FDIC makes a special assessment to fund the repayment of debt obligations of the Financing Corporation, or FICO. FICO is a government-sponsored entity that was formed to borrow the money necessary to carry out the closing and ultimate disposition of failed thrift institutions by the Resolution Trust Corporation in the 1990s. The FICO assessment rate for the first quarter of 20162019 is 0.5800.14 basis points on an annualized basis.
The FDIC may terminate the deposit insurance of any insured depository institution if it determines after a hearing that the institution has engaged in unsafe or unsound practices, is in an unsafe or unsound condition to continue operations or has violated any applicable law, regulation, rule, order or condition imposed by the FDIC or the Federal Reserve Board. It also may suspend deposit insurance temporarily during the hearing process if the institution has no tangible capital. If insurance of accounts is terminated, the accounts at the institution at the time of termination, less subsequent withdrawals, will continue to be insured for a period of six months to two years, as determined by the FDIC.
Under federal law, deposits and certain claims for administrative expenses and employee compensation against insured depository institutions are afforded a priority over other general unsecured claims against such an institution, including federal funds and letters of credit, in the liquidation or other resolution of such an institution by a receiver. Such priority creditors would include the FDIC.
Capital
The Federal Reserve Board and the FDIC have issued substantially similar minimum risk-based and leverage capital rules applicable to banking organizations they supervise. At December 31, 2015,2018, both S&T and S&T Bank met the applicable minimum regulatory capital requirements. S&T’s

In addition, the banking regulatory agencies may from time to time require that a banking organization maintain capital above the minimum prescribed levels, whether because of its financial condition or actual or anticipated growth.
The risk-based capital standards establish a systematic analytical framework that makes regulatory capital requirements more sensitive to differences in risk profiles among banking organizations, takes off-balance sheet exposures explicitly into account in assessing capital adequacy and minimizes disincentives to holding liquid, low-risk assets. For purposes of the risk-based ratios, assets and specified off-balance sheet instruments are assigned to broad risk categories, each with appropriate weights. The resulting capital ratios represent capital as a percentage of total risk-weighted assets and off-balance sheet items. The leverage ratio represents capital as a percentage of total average assets adjusted as specified in the guidelines.
In July 2013 the federal banking agencies issued a final ruleregulatory capital rules that replaced the then existing general risk-based capital and related rules, broadly revising the basic definitions and elements of regulatory capital and making substantial changes to the risk weightings for banking and trading book assets. The new regulatory capital rules are designed to implement Basel III (which were agreements reached in July 2010 by the international oversight body of the Basel Committee on Banking Supervision to require more and higher-quality capital) as well as the minimum leverage and risk-based capital requirements of the Dodd-Frank Act. The final rule establishes a comprehensiveThese new capital framework,standards apply to all banks, regardless of size, and went into effectto all bank holding companies with consolidated assets greater than $500 million, and became effective on January 1, 2015, for2015. For smaller banking organizations such as S&T and S&T Bank. It introducesBank, the rules are subject to a commontransition period providing for full implementation as of January 1, 2019.
The required regulatory capital minimum ratios under the new capital standards as of December 31, 2018 are as follows:
Common equity Tier 1 risk-based capital ratio requirement(common equity Tier 1 capital to standardized total risk-weighted assets) of 4.50 percent, increases the minimum percent;
Tier 1 risk-based capital ratio (Tier 1 capital to standardized total risk-weighted assets) of 6.00 percent,percent;

Generally, under the guidelines, common equity Tier 1 capital consists of common stock instruments that meet the eligibility criteria in the rule, retained earnings, accumulated other comprehensive income and common equity Tier 1 minority interest. interest, less applicable regulatory adjustments and deductions including goodwill, intangible assets subject to limitation and certain deferred tax assets subject to limitation. Tier 1 capital is comprised of common equity Tier 1 capital plus generally non-cumulative perpetual preferred stock, Tier 1 minority interests and, for bank holding companies with less than $15 billion in consolidated assets at December 31, 2009, certain restricted capital instruments including qualifying cumulative perpetual preferred stock and grandfathered trust preferred securities, up to a limit of 25 percent of Tier 1 capital, less applicable regulatory adjustments and deductions. Tier 2, or supplementary, capital generally includes portions of trust preferred securities and cumulative perpetual preferred stock not otherwise counted in Tier 1 capital, as well as preferred stock, subordinated debt, total capital minority interests not included in Tier 1, and the allowance for loan losses in an amount not exceeding 1.25 percent of standardized risk-weighted assets, less applicable regulatory adjustments and deductions. Total capital is the sum of Tier 1 and Tier 2 capital.
The new regulatory capital rule also requires a banking organization to maintain a capital conservation buffer composed of common equity Tier 1 capital in an amount greater than 2.50 percent of total risk-weighted assets beginning in 2019. TheBeginning in 2016, the capital conservation buffer will bewas phased in, beginning in 2016, at 25 percent, increasing to 50 percent in 2017, 75 percent in 2018 and 100 percent in 2019 and beyond. As a result, starting in 2019, a banking organization must maintain a common equity Tier 1 risk-based capital ratio greater than 7.00 percent, a Tier 1 risk-based capital ratio greater than 8.50 percent and a Total risk-based capital ratio greater than 10.50 percent; otherwise, it will be subject to restrictions on capital distributions and discretionary bonus payments. By 2019, when the new rule is fully phased in, the minimum capital requirements plus the capital conservation buffer will exceed the regulatory capital ratios required for an insured depository institution to be well-capitalized under prompt corrective action law, described below.
The new regulatory capital rule also revises the calculation of risk-weighted assets. It includes a new framework under which the risk weight will increase for most credit exposures that are 90 days or more past due or on nonaccrual, high-volatility commercial real estate loans, mortgage servicing and deferred tax assets that are not deducted from capital and certain equity exposures. It also includes changes to the credit conversion factors of off-balance sheet items, such as the unused portion of a loan commitment.
Federal regulators periodically propose amendments to the regulatory capital rules and the related regulatory framework and consider changes to the capital standards that could significantly increase the amount of capital needed to meet applicable standards. The timing of adoption, ultimate form and effect of any such proposed amendments cannot be predicted.

Payment of Dividends
S&T is a legal entity separate and distinct from its banking and other subsidiaries. A substantial portion of our revenues consist of dividend payments we receive from S&T Bank. The payment of common dividends by S&T is subject to certain requirements and limitations of Pennsylvania law. S&T Bank, in turn, is subject to federal and state laws and regulations that limit the amount of dividends it can pay to S&T. In addition, both S&T and S&T Bank are subject to various general regulatory policies relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. The Federal Reserve Board has indicated that banking organizations should generally pay dividends only if (i) the organization’s net income available to common shareholders over the past year has been sufficient to fully fund the dividends and (ii) the prospective rate of earnings retention appears consistent with the organization’s capital needs, asset quality and overall financial condition. Thus, under certain circumstances based upon our financial condition, our ability to declare and pay quarterly dividends may require consultation with the Federal Reserve Board and may be prohibited by applicable Federal Reserve Board guidance.
Other Safety and Soundness Regulations
There are a number of obligations and restrictions imposed on bank holding companies such as us and our depository institution subsidiary by federal law and regulatory policy. These obligations and restrictions are designed to reduce potential loss exposure to the FDIC’s deposit insurance fundDIF in the event an insured depository institution becomes in danger of default or is in default. Under current federal law, for example, the federal banking agencies possess broad powers to take prompt corrective action to resolve problems of insured depository institutions. The extent of these powers depends upon whether the institution in question is “well-capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized” or “critically undercapitalized,” as defined by the law. As of December 31, 2015,2018, S&T Bank was classified as “well-capitalized.” New definitions of these categories, as set forth in the federal banking agencies’ final rule to implement Basel III and the minimum leverage and risk-based capital requirements of the Dodd-Frank Act, became effective as of January 1, 2015. To be well-capitalized, an insured depository institution must have a common equity Tier 1 risk-based capital ratio of at least 6.50 percent, a Tier 1 risk-based capital ratio of at least 8.00 percent, a total risk-based capital ratio of at least 10.00 percent and a leverage ratio of at least 5.00 percent.percent, and the institution must not be subject to any written agreement, order, capital directive or prompt corrective action directive by its primary federal regulator. To be adequately capitalized, an insured depository institution must have a common equity Tier 1 risk-based capital ratio of at least 4.50 percent, a Tier 1 risk-based capital ratio of at least 6.00 percent, a total risk-based capital ratio of at least 8.00 percent and a leverage ratio of at least 4.00 percent. The classification of depository institutions is primarily for the purpose of applying the federal banking agencies’ prompt corrective action provisions and is not intended to be and should not be interpreted as a representation of overall financial condition or prospects of any financial institution.
The federal banking agencies’ prompt corrective action powers, (whichwhich increase depending upon the degree to which an institution is undercapitalized)undercapitalized, can include, among other things, requiring an insured depository institution to adopt a capital

restoration plan, which cannot be approved unless guaranteed by the institution’s parent company; placing limits on asset growth and restrictions on activities, including restrictions on transactions with affiliates; restricting the interest rates the institution may pay on deposits; restricting the institution from accepting brokered deposits; prohibiting the payment of principal or interest on subordinated debt; prohibiting the holding company from making capital distributions, including payment of dividends, without prior regulatory approval; and, ultimately, appointing a receiver for the institution. For example, only a “well-capitalized” depository institution may accept brokered deposits without prior regulatory approval.
The federal banking agencies have also adopted guidelines prescribing safety and soundness standards relating to internal controls and information systems, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth, fees and compensation and benefits. In general, the guidelines require appropriate systems and practices to identify and manage specified risks and exposures. The guidelines prohibit excessive compensation as an unsafe and unsound practice and characterize compensation as excessive when the amounts paid are unreasonable or disproportionate to the services performed by an executive officer, employee, director or principal shareholder. In addition, the agencies have adopted regulations that authorize, but do not require, an agency to order an institution that has been given notice by an agency that it is not in compliance with any of such safety and soundness standards to submit a compliance plan. If, after being so notified, an institution fails to submit an acceptable compliance plan, the agency must issue an order directing action to correct the deficiency and may issue an order directing other actions of the types to which an “undercapitalized” institution is subject under the prompt corrective action provisions described above.

Item 1.  BUSINESS -- continued




Regulatory Enforcement Authority
The enforcement powers available to federal banking agencies are substantial and include, among other things and in addition to other powers described herein, the ability to assess civil money penalties and impose other civil and criminal penalties, to issue cease-and-desist or removal orders, to appoint a conservator to conserve the assets of an institution for the benefit of its depositors and creditors and to initiate injunctive actions against banks and bank holding companies and “institution affiliated parties,” as defined in the Federal Deposit Insurance Act. In general, these enforcement actions may be initiated for violations of laws and regulations, as well asand engagement in unsafe or unsound practices. Other actions or inactions may provide the basis for enforcement action, including misleading or untimely reports filed with regulatory authorities.
At the state level, the PADBS also has broad enforcement powers over S&T Bank, including the power to impose fines and other penalties and to appoint a conservator or receiver.
Interstate Banking and Branching
The BHCA currently permits bank holding companies from any state to acquire banks and bank holding companies located in any other state, subject to certain conditions, including certain nationwide and state-imposed deposit concentration limits. In addition, because of changes to law made by the Dodd-Frank Act, S&T Bank may now establish de novo branches in any state to the same extent that a bank chartered in that state could establish a branch.
Community Reinvestment, Fair Lending and Consumer Protection Laws
In connection with its lending activities, S&T Bank is subject to a number of state and federal laws designed to protect borrowers and promote lending to various sectors of the economy and population. The federal laws include, among others, the Equal Credit Opportunity Act, the Truth-in-Lending Act, the Truth-in-Savings Act, the Home Mortgage Disclosure Act, the Real Estate Settlement Procedures Act, the Fair Credit Reporting Act and the CRA. In addition, rules of the Consumer Financial Protection Bureau, or CFPB, pursuant to federal lawrules require disclosure of privacy policies to consumers and, in some circumstances, allow consumers to prevent the disclosure of certain personal information to nonaffiliated third parties.
The CRA requires the appropriate federal banking agency, in connection with its examination of a bank, to assess the bank’s record in meeting the credit needs of the communities served by the bank, including low and moderate-income neighborhoods. Furthermore, such assessment is required of any bank that has applied, among other things, to merge or consolidate with or acquire the assets or assume the liabilities of an insured depository institution, or to open or relocate a branch office. In the case of a bank holding company, (includingincluding a financial holding company)company, applying for approval to acquire a bank or bank holding company, the Federal Reserve Board will assess the record of each subsidiary bank of the applicant bank holding company in considering the application. Under the CRA, institutions are assigned a rating of “outstanding,” “satisfactory,” “needs to improve” or “unsatisfactory.” S&T Bank was rated “satisfactory” in its most recent CRA evaluation.
With respect to consumer protection, the Dodd-Frank Act created the Consumer Financial Protection Bureau, or the CFPB, which took over rulemaking responsibility on July 21, 2011 for the principal federal consumer financial protection laws, such as those identified above. Institutions that have assets of $10 billion or less, such as S&T Bank, are subject to the rules established by the CFPB but will continue to be supervised in this area by their state and primary federal regulators, which in the case of S&T Bank is the FDIC. The Dodd-Frank Act also gives the CFPB expanded data collection powers for fair lending purposes for both small business and mortgage loans, as well as expanded authority to prevent unfair, deceptive and abusive practices. The consumer complaint function also has been consolidated into the CFPB with respect to the institutions it supervises. The CFPB established an Office of Community Banks and Credit Unions, with a mission to ensure that the CFPB incorporates the perspectives of small depository institutions into the policy-making process, communicates relevant policy initiatives to community banks and credit unions, and works with community banks and credit unions to identify potential areas for regulatory simplification.
Fair lending laws prohibit discrimination in the provision of banking services, and the enforcement of these laws has been a focus for bank regulators. Fair lending laws includedinclude the Equal Credit Opportunity Act and the Fair Housing Act, which outlaw discrimination in credit transactions and residential real estate on the basis of prohibited factors including, among others, race, color, national origin, sex and religion. A lender may be liable for policies that result in a disparate treatment of or have a disparate impact on a protected class of applicants or borrowers. If a pattern or practice of lending discrimination is alleged by a regulator, then that agency may refer the matter to the U.S. Department of Justice, or DOJ, for investigation. In December of 2012, the DOJ and the CFPB entered into a Memorandum of Understanding under which the agencies have agreed to share

S&T Bank is required to have a fair lending program that is of sufficient scope to monitor the inherent fair lending risk of the institution and that appropriately remediates issues which are identified.

During 2013, the CFPB issued a series of final rules related to mortgage loan origination and mortgage loan servicing. In particular, on January 10, 2013, the CFPB issued a final rule implementing the ability-to-repay and qualified mortgage (QM) provisions of the Truth-in-Lending Act, as amended by the Dodd-Frank Act (“QM Rule”). The ability-to-repay provision requires creditors to make reasonable, good-faith determinations that borrowers are able to repay their mortgage loans before extending the credit, based on a number of factors and consideration of financial information about the borrower from reasonably reliable third-party documents. Under the Dodd-Frank Act and the QM Rule, loans meeting the definition of “qualified mortgage” are entitled to a presumption that the lender satisfied the ability-to-repay requirements. The presumption is a conclusive presumption/safe harbor for prime loans meeting the QM requirements, and a rebuttable presumption for higher-priced/subprime loans meeting the QM requirements. The definition of a QM incorporates the statutory requirements, such as not allowing negative amortization or terms longer than 30 years. The QM Rule also adds an explicit maximum 43 percent debt-to-income ratio for borrowers if the loan is to meet the QM definition, though some mortgages that meet government-sponsored enterprise, or GSE, Federal Housing Administration, or FHA, and Veterans Affairs, or VA, underwriting guidelines may, for a period not to exceed seven years, meet the QM definition without being subject to the 43 percent debt-to-income limits. The QM Rule became effective on January 10, 2014. These rules did not have a material impact on our mortgage business.
In November 2013, the CFPB issued a final rule implementing the Dodd-Frank Act requirement to establish integrated disclosures in connection with mortgage origination, which incorporates disclosure requirements under the Real Estate Settlement Procedures Act and the Truth-in-Lending Act. The requirements of the final rule apply to all covered mortgage transactions for which S&T Bank receives a consumer application on or after October 3, 2015. The CFPB issued a final rule regarding the integrated disclosures in December 2013, and the disclosure requirement became effective in October 2015. These rules did not have a material impact on our mortgage business.
Anti-Money Laundering Rules
S&T Bank is subject to the Bank Secrecy Act, its implementing regulations and other anti-money laundering laws and regulations, including the USA Patriot Act of 2001. Among other things, these laws and regulations require S&T Bank to take steps to prevent the bank from being used to facilitate the flow of illegal or illicit money, to report large currency transactions and to file suspicious activity reports. S&T Bank is also required to develop and implement a comprehensive anti-money laundering compliance program. Banks must also have in place appropriate “know your customer” policies and procedures. Violations of these requirements can result in substantial civil and criminal sanctions. In addition, provisions of the USA Patriot Act of 2001 require the federal financial institution regulatory agencies to consider the effectiveness of a financial institution’s anti-money laundering activities when reviewingconsidering applications for bank mergers and bank holding company acquisitions.
Government Actions and LegislationOther Dodd-Frank Provisions
The Dodd-Frank Act is significantly changing the current bank regulatory structure and affecting the lending, deposit, investment, trading and operating activities of financial institutions and their holding companies, including S&T and S&T Bank. The Dodd-Frank Act contains a number of provisions intended to strengthen capital. Refer to Capital within Part I, Item 1 for additional information.
The Dodd-Frank Act requires various federal agencies to adopt a broad range of new rules and regulations and to prepare numerous studies and reports for Congress. The federal agencies are given significant discretion in drafting the implementing rules and regulations, and consequently, many of the details and much of the impact of the Act depend on the actions of regulatory agencies. The Dodd-Frank Act also contains provisions that expand the insurance assessment base and increase the scope of deposit insurance coverage.
Among other provisions, the SEC has enacted rules, required by the Dodd-Frank Act, giving stockholders a non-binding vote on executive compensation and so-called “golden parachute” payments and allowing certain stockholders to nominate their own candidates for election as directors using a company’s proxy materials. The legislation also directs the federal financial institution regulatory agencies to promulgate rules prohibiting excessive compensation being paid to financial institution executives. In addition, in December of 2013, federal regulators adopted final regulations regarding the so-called Volcker Rule established in the Dodd-Frank Act. The Volcker Rule generally prohibits banks and their affiliates from engaging in proprietary trading and investing in and sponsoring certain unregistered investment companies (generallygenerally covering hedge funds and private equity funds, subject to certain exemptions). The rules are complex andexemptions. Banking entities had until July 21, 2017 to conform their activities to the conformance date for mostrequirements of the prohibitions was July 21, 2015. However,rule. Because S&T generally does not currently anticipate that they will haveengage in the activities prohibited by the Volcker Rule, the effectiveness of the rule has not had a material effect on S&T Bank or its affiliates, because we do not engage in the prohibited activities.affiliates.
The Dodd-Frank Act also created the CFPB, that took over rulemaking responsibility on July 21, 2011 for the principal federal consumer financial protection laws, such as the Truth in Lending Act, the Equal Credit Opportunity Act, the Real Estate Settlement Procedures Act, or RESPA, and the Truth in Savings Act, among others. Institutions that have assets of $10.0 billion or less, such as S&T Bank, will continue to be supervised in this area by their state and primary federal regulators (in the case of S&T Bank, the FDIC). The Act also gives the CFPB expanded data collection powers for fair lending purposes for both small business and mortgage loans, as well as expanded authority to prevent unfair, deceptive and abusive practices. The consumer complaint function also has been consolidated into the CFPB with respect to the institutions it supervises. The CFPB established an Office of Community Banks and Credit Unions, with a mission to ensure that the CFPB incorporates the perspectives of small depository institutions into the policy-making process, communicates relevant policy initiatives to community banks and credit unions, and works with community banks and credit unions to identify potential areas for regulatory simplification. In addition, the Dodd-Frank Act requiredprovides that the amount of any interchange fee charged for electronic debit transactions by debit card issuers having assets over $10 billion must be reasonable and proportional to the actual cost of a transaction to the issuer. The Federal Reserve Board to adopthas adopted a rule addressingwhich limits the maximum permissible interchange fees applicable tothat such issuers can receive for an electronic debit card transactions.transaction. This rule, Regulation II, which was effective October 1, 2011, does not apply to a bank that, together with its affiliates, has less than $10.0$10 billion in assets.
In January 2013, the CFPB issued a series of final rules related to mortgage loan origination and mortgage loan servicing. In particular, on January 10, 2013, the CFPB issued a final rule implementing the ability-to-repay and qualified mortgage (QM) provisions of the Truth in Lending Act, as amended by the Dodd-Frank Act (the “QM Rule”). The ability-to-repay provision requires creditors to make reasonable, good-faith determinations that borrowers are able to repay their mortgage loans before extending the credit based on a number of factors and consideration of financial information about the borrower from reasonably reliable third-party documents. Under the Dodd-Frank Act and the QM Rule, loans meeting the definition of “qualified mortgage” are entitled to a presumption that the lender satisfied the ability-to-repay requirements. The presumption is a conclusive presumption/safe harbor for prime loans meeting the QM requirements, and a rebuttable presumption for higher-priced/subprime loans meeting the QM requirements. The definition of a “qualified mortgage” incorporates the statutory

requirements, such as not allowing negative amortization or terms longer than 30 years. The QM Rule also adds an explicit maximum 43 percent debt-to-income ratio for borrowers if the loan is to meet the QM definition, though some mortgages that meet government-sponsored enterprise, or GSE, Federal Housing Administration, or FHA, and Veterans Affairs, or VA, underwriting guidelines may, for a period not to exceed seven years, meet the QM definition without being subject to the 43 percent debt-to-income limits. The QM Rule became effective on January 10, 2014. These rules did not have a material impact on our mortgage business.
In November 2013, the CFPB issued a final rule implementing the Dodd-Frank Act requirement to establish integrated disclosures in connection with mortgage origination,assets, which incorporates disclosure requirements under RESPA and TILA. The requirements of the final rule apply to all covered mortgage transactions for whichincludes S&T Bank receives a consumer application on or after October 3, 2015. CFPB issued a final rule regarding the integrated disclosures in December 2013, and the disclosure requirement became effective in October 2015. These rules did not have a material impact on our mortgage business.
The federal agencies responsible for implementing the provisions of the Dodd-Frank Act have issued a substantial number of rules. More rules will be issued. Not all of the Dodd-Frank Act provisions and their implementing regulations apply to banks the size of S&T Bank. Federal and state regulatory agencies consistently propose and adopt changes to their regulations or change the manner in which existing regulations are applied. We cannot assess the ultimate impact of the Act on S&T or S&T Bank at this time, including the extent to which it could increase costs or limit our ability to pursue business opportunities in an efficient manner, or otherwise adversely affect our business, financial condition and results of operations. Nor can we predict the impact or substance of other future legislation or regulation. However, it is expected that they, at a minimum, will increase our operating and compliance costs.
We cannot predict the substance or impact of pending or future legislation or regulation, or the application thereof, although enactment of any proposed legislation could affect how S&T and S&T Bank operate and could significantly increase costs, impede the efficiency of internal business processes, or limit our ability to pursue business opportunities in an efficient manner, any of which could materially and adversely affect our business, financial condition and results of operations.&T.
Competition
S&T Bank competes with other local, regional and national financial services providers, such as other financial holding companies, commercial banks, savings associations, credit unions, finance companies and brokerage and insurance firms, including competitors that provide their products and services online.online and through mobile devices. Some of our competitors are not subject to the same level of regulation and oversight that is required of banks and bank holding companies, and are thus able to operate under lower cost structures. Our wealth management business competes with trust companies, mutual fund companies, investment advisory firms, law firms, brokerage firms and other financial services companies.

Item 1.  BUSINESS -- continued




Changes in bank regulation, such as changes in the products and services banks can offer and permitted involvement in non-banking activities by bank holding companies, as well as bank mergers and acquisitions, can affect our ability to compete with other financial services providers. Our ability to do so will depend upon how successfully we can respond to the evolving competitive, regulatory, technological and demographic developments affecting our operations.
Our market area includescustomers are primarily in Pennsylvania and the contiguous states of Ohio, West Virginia, New York, Maryland and Maryland.Delaware. The majority of our commercial and consumer loans are made to businesses and individuals in this market areathese states resulting in a geographic concentration. Our market area has a high density of financial institutions, some of which are significantly larger institutions with greater financial resources than us, and many of which are our competitors to varying degrees. Our competition for loans comes principally from commercial banks, savings associations, mortgage banking companies, credit unions and other financial service companies. Our most direct competition for deposits has historically come from commercial banks, savings banks and credit unions. We face additional competition for deposits from non-depository competitors such as the mutual fund industry, securities and brokerage firms and insurance companies. Because larger competitors have advantages in attracting business from larger corporations, we do not generally attempt to compete for that business. Instead, we concentrate our efforts on attracting the business of individuals, and small and medium-size businesses. We consider our competitive advantages to be customer service and responsiveness to customer needs, the convenience of banking offices and hours, access to electronic banking services and the availability and pricing of our products and services. We emphasize personalized banking and the advantage of local decision-making in our banking business.
The financial services industry is likely to become more competitive as further technological advances enable more companies to provide financial services on a more efficient and convenient basis. Technological innovations have lowered traditional barriers to entry and enabled many companies to compete in financial services markets. Many customers now expect a choice of banking options for the delivery of services, including traditional banking offices, telephone, internet, mobile, ATMs, self-service branches, in-store branches and/or in-store branches.digital and technology based solutions. These delivery channels are offered by traditional banks and savings associations, as well as credit unions, brokerage firms, asset management groups, financial technology companies, finance and insurance companies, internet-based companies, and mortgage banking firms.

Item 1A.  RISK FACTORS
Investments in our common stock involve risk. The following discussion highlights the risks that we believe are material to S&T, but does not necessarily include all risks that we may face.
The market price of our common stock may fluctuate significantly in response to a number of factors.
Our quarterly and annual operating results have varied significantly in the past and could vary significantly in the future, which makes it difficult for us to predict our future operating results. Our operating results may fluctuate due to a variety of factors, many of which are outside of our control, including the changing U.S. economic environment and changes in the commercial and residential real estate market, any of which may cause our stock price to fluctuate. If our operating results fall below the expectations of investors or securities analysts, the price of our common stock could decline substantially. Our stock price can fluctuate significantly in response to a variety of factors including, among other things:
volatility of stock market prices and volumes in general;
changes in market valuations of similar companies;
changes in the conditions inof credit markets;
changes in accounting policies or procedures as required by the Financial Accounting Standards Board, or FASB, or other regulatory agencies;
legislative and regulatory actions, (includingincluding the impact of the Dodd-Frank Act and related regulations) subjectingregulations, that may subject us to additional regulatory oversight which may result in increased compliance costs and/or require us to change our business model;
government intervention in the U.S. financial system and the effects of and changes in trade and monetary and fiscal policies and laws, including the interest rate policies of the Federal Reserve;Reserve Board;
additions or departures of key members of management;
fluctuations in our quarterly or annual operating results; and
changes in analysts’ estimates of our financial performance.
Risks Related to Credit
Our ability to assess the credit-worthiness of our customers may diminish, which may adversely affect our results of operations.
We takeincur credit risk by virtue of making loans and extending loan commitments and letters of credit. Credit risk is one of our most significant risks. Our exposure to credit risk is managed through the use of consistent underwriting standards that emphasize “in-market” lending while avoiding highly leveraged transactions as well as excessive industry and other concentrations. Our credit administration function employs risk management techniques to ensure that loans adhere to corporate policy and problem loans are promptly identified. There can be no assurance that such measures will be effective in avoiding undue credit risk. If the models and approaches that we use to select, manage and underwrite our consumer and commercial loan products become less predictive of future charge-offs, (due, for example,due to events adversely affecting our customers, including rapid changes in the economy, including the unemployment rate), our credit losses may increase.
The value of the collateral used to secure our loans may not be sufficient to compensate for the amount of an unpaid loan and we may be unsuccessful in recovering the remaining balancebalances from our customers.
Decreases in real estate values, particularly with respect to our commercial lending and mortgage activities, could adversely affect the value of property used as collateral for our loans and our customers’ ability to repay these loans, which in turn could impact our profitability. Repayment of our commercial loans is often dependent on the cash flow of the borrower, which may become unpredictable. If the value of the assets, such as real estate, serving as collateral for the loan portfolio were to decline materially, a significant part of the loan portfolio could become under-collateralized. If the loans that are secured by real estate become troubled when real estate market conditions are declining or have declined, in the event of foreclosure, we may not be able to realize the amount of collateral that was anticipated at the time of originating the loan. This could result in higher charge-offs which could have a material adverse effect on our operating results and financial condition.
Changes in the overall credit quality of our portfolio can have a significant impact on our earnings.
Like other lenders, we face the risk that our customers will not repay their loans. We reserve for losses in our loan portfolio based on our assessment of inherent credit losses. This process, which is critical to our financial results and condition, requires complex judgment including our assessment of economic conditions, which are difficult to predict. Through a periodic review of the loan portfolio, management determines the amount of the allowance for loan loss,losses, or ALL, by considering historical losses combined with qualitative factors including changes in lending policies and practices, economic conditions, changes in the loan portfolio, changes in lending management, results of internal loan reviews, asset quality trends, collateral values,

10Item 1A.  RISK FACTORS - continued


concentrations of credit risk and other external factors. The amount of future losses is susceptible to changes in economic, operating and other conditions, including changes in interest rates, which may be beyond our control. Although we have policies and procedures in place to determine future losses, due to the subjective nature of this area, there can be no assurance that our management has accurately assessed the level of allowances reflected in our Consolidated Financial Statements. We may underestimate our inherent losses and fail to hold an ALL sufficient to account for these losses. Incorrect assumptions could lead to material underestimates of inherent losses and an inadequate ALL. As our assessment of inherent losses changes, we may need to increase or decrease our ALL, which could significantly impact our financial results and profitability.
Our loan portfolio is concentrated within our market area, and our lack of geographic diversification increases our risk profile.
The regional economic conditions within our market area affect the demand for our products and services as well as the ability of our customers to repay their loans and the value of the collateral securing these loans. We are less able than a larger institution to spread the risks of unfavorable local economic conditions across a large number of diversified economies. A significant decline in the regional economy caused by inflation, recession, unemployment or other factors could negatively affect our customers, the quality of our loan portfolio and the demand for our products and services. Any sustained period of increased payment delinquencies, foreclosures or losses caused by adverse market or economic conditions in our market area could adversely affect the value of our assets, revenues, results of operations and financial condition. Moreover, we cannot give any assurance that we will benefit from any market growth or favorable economic conditions in our primary market area.
Our loan portfolio has a significant concentration of commercial real estate loans.
The majority of our loans are to commercial borrowers. Theborrowers and 53 percent of our total loans are commercial real estate, or CRE, and construction loans with real estate as the primary collateral. The CRE segment of our loan portfolio typically involves higher loan principal amounts, and the repayment of these loans is generally dependent, in large part, on sufficient income from the properties securing the loans to cover operating expenses and debt service. Because payments on loans secured by CRE often depend upon the successful operation and management of the properties, repayment of these loans may be affected by factors outside the borrower’s control, including adverse conditions in the real estate market or the economy. Additionally, we have a number of significant credit exposures to commercial borrowers, and while the majority of these borrowers have numerous projects that make up the total aggregate exposure, if one or more of these borrowers default or have financial difficulties, we could experience higher credit losses, which could adversely impact our financial condition and results of operations. In December 2015, the FDIC and the other federal financial institution regulatory agencies released a new statement on prudent risk management for commercial real estate lending. In it,this statement, the agencies express concerns about easing commercial real estate underwriting standards, direct financial institutions to maintain underwriting discipline and exercise risk management practices to identify, measure and monitor lending risks, and indicate that they will continue to pay special attention to commercial real estate lending activities and concentrations going forward.
Risks Related to Our Operations
An interruption or security breachFailure to keep pace with technological changes could have a material adverse effect on our results of operations and financial condition.
The financial services industry is constantly undergoing rapid technological change with frequent introductions of new technology-driven products and services. The effective use of technology increases efficiency and enables financial institutions to better service customers and reduce costs. Our future success depends, in part, upon our ability to address the needs of our information systemscustomers by using technology to provide products and services that will satisfy their demands, as well as create additional efficiencies within our operations. Many of our large competitors have substantially greater resources to invest in technological improvements. We may resultnot be able to effectively implement new technology-driven products and services quickly or be successful in financial losses or in a loss of customers.
We depend upon data processing, communicationmarketing these products and information exchange on a variety of computing platforms and networks, including the internet. We have experienced cyber security incidents in the past, which we did not deem material, and may experience them in the future. We believe that we have implemented appropriate measures to mitigate potential risksservices to our technology and our operations from these information technology disruptions. However, we cannot be certain that all of our systems are entirely free from vulnerabilitycustomers. Failure to attack, despite safeguards we have instituted. The occurrence of any failures, interruptions or security breaches of our information systems could disrupt our continuity of operations or result insuccessfully keep pace with technological change affecting the disclosure of sensitive, personal customer information whichfinancial services industry could have a material adverse impact on our business, financial condition and results of operations.

We rely on our employees and third parties in our day-to-day and ongoing operations, who may, as a result of human error, misconduct or malfeasance, or failure or breach of third- party systems or infrastructure, expose us to risk. We have taken measures to implement backup systems and other safeguards to support our operations, but our ability to conduct business may be adversely affected by any significant disruptions to us or to third parties with whom we interact. In addition, our ability to implement backup systems and other safeguards with respect to third-party systems is more limited than with our own systems.
We handle a substantial volume of customer business, remedial costs, additional regulatory scrutinyand other financial transactions every day. Our financial, accounting, data processing, check processing, electronic funds transfer, loan processing, online and mobile banking, automated teller machines, or exposureATMs, backup or other operating or security systems and infrastructure may fail to civil litigation and possible financial liability. Losses arising from suchoperate properly or become disabled or damaged as a breach could materially exceed the amountresult of insurance coverage we have, whicha number of factors including events that are wholly or partially beyond our control. This could adversely affect our ability to process these transactions or provide these services. There could be sudden increases in customer transaction volume, electrical, telecommunications or other major physical infrastructure outages, natural disasters, events arising from local or larger scale political or social matters, including terrorist acts, and cyber attacks. We continuously update these systems to support our operations and growth. This updating entails significant costs and creates risks associated with implementing new systems and integrating them with existing ones. Operational risk exposures could adversely impact our results of operation.operations, liquidity and financial condition, and cause reputational harm.
A cyber attack, information or security breach, or a technology failure of ours or of a third-party could adversely affect our ability to conduct our business or manage our exposure to risk, result in the disclosure or misuse of confidential or proprietary information, increase our costs to maintain and update our operational and security systems and infrastructure, and adversely impact our results of operations, liquidity and financial condition, as well as cause reputational harm.
Our business is highly dependent on the security and efficacy of our infrastructure, computer and data management systems, as well as those of third parties with whom we interact. Cyber security risks for financial institutions have significantly increased in recent years in part because of the proliferation of new technologies, the use of the Internet and telecommunications technologies to conduct financial transactions, and the increased sophistication and activities of organized crime, hackers, terrorists and other external parties, including foreign state actors. Our operations rely on the secure processing, transmission, storage and retrieval of confidential, proprietary and other information in our computer and data management systems and networks, and in the computer and data management systems and networks of third parties. We rely on digital technologies, computer, database and email systems, software, and networks to conduct our operations. In addition, to access our network, products and services, our customers and third parties may use personal mobile devices or computing devices that are outside of our network environment.
Financial services institutions have been subject to, and are likely to continue to be the target of, cyber attacks, including computer viruses, malicious or destructive code, phishing attacks, denial of service or other security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of confidential, proprietary and other information of the institution, its employees or customers or of third parties, or otherwise materially disrupt network access or business operations. For example, denial of service attacks have been launched against a number of large financial institutions and several large retailers have disclosed substantial cyber security breaches affecting debit and credit card accounts of their customers. We have experienced cyber security incidents in the past, although not material, and we anticipate that, as a growing regional bank, we could experience further incidents. There can be no assurance that we will not suffer material losses or other material consequences relating to technology failure, cyber attacks or other information or security breaches.
In addition to external threats, insider threats also represent a risk to us. Insiders, having legitimate access to our systems and the information contained in them, have the opportunity to make inappropriate use of the systems and information. We have policies, procedures, and controls in place designed to prevent or limit this risk, but we cannot guarantee that these policies, procedures and controls fully mitigate this risk.

Item 1A.  RISK FACTORS - continued
As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify and enhance our protective measures or to investigate and remediate any information security vulnerabilities or incidents. Any of these matters could result in our loss of customers and business opportunities, significant disruption to our operations and business, misappropriation or destruction of our confidential information and/or that of our customers, or damage to our customers’ and/or third parties’ computers or systems, and could result in a violation of applicable privacy laws and other laws, litigation exposure, regulatory fines, penalties or intervention, loss of confidence in our security measures, reputational damage, reimbursement or other compensatory costs, and additional compliance costs. In addition, any of the matters described above could adversely impact our results of operations and financial condition.
We rely on third-party providers and other suppliers for a number of services that are important to our business. An interruption or cessation of an important service by any third partythird-party could have a material adverse effect on our business.
We are dependent for the majority of our technology, including our core operating system, on third partythird-party providers. If these companies were to discontinue providing services to us, we may experience significant disruption to our business. In addition, each of these third parties faces the risk of cyber attack, information breach or loss, or technology failure. If any of our third partythird-party service providers experience financial, operational or technologicalsuch difficulties, or if there is any other disruption in our relationships with them, we may be required to locatefind alternative sources of such services. We are dependent on these third-party providers securing their information systems, over which we have nolimited control, and a breach of their information systems

could adversely affect our ability to process transactions, service our clients or manage our exposure to risk and could result in the disclosure of sensitive, personal customer information, which could have a material adverse impact on our business through damage to our reputation, loss of customer business, remedial costs, additional regulatory scrutiny or exposure to civil litigation and possible financial liability. Assurance cannot be provided that we could negotiate terms with alternative service sources that are as favorable or could obtain services with similar functionality as found in existing systems without the need to expend substantial resources, if at all, thereby resulting in a material adverse impact on our business and results of operations.
Risks Related to Interest Rates and Investments
Our net interest income could be negatively affected by interest rate changes which may adversely affect our financial condition.
Our results of operations are largely dependent on net interest income, which is the difference between the interest and fees earned on interest-earning assets and the interest paid on interest-bearing liabilities. Therefore, any change in general market interest rates, including changes resulting from the Federal Reserve Board’s policies, can have a significant effect on our net interest income and total income. There may be mismatches between the maturity and repricing of our assets and liabilities that could cause the net interest rate spread to compress, depending on the level and type of changes in the interest rate environment. Interest rates could remain at historical low levels causing rate spread compression over an extended period of time. Interest rates are highly sensitive to many factors that are beyond our control, including general economic conditions and the policies of various governmental agencies. In addition, some of our customers often have the ability to prepay loans or redeem deposits with either no penalties, or penalties that are insufficient to compensate us for the lost income. A significant reduction in our net interest income will adversely affect our business and results of operations. If we are unable to manage interest rate risk effectively, our business, financial condition and results of operations could be materially harmed.
Declines in the value of investment securities held by us could require write-downs, which would reduce our earnings.
In order to diversify earnings and enhance liquidity, we own both debt and equity instruments of government agencies, municipalities and other companies. We may be required to record impairment charges on our investmentdebt securities if they suffer a decline in value that is considered other-than-temporary. Additionally, the value of these investments may fluctuate depending on the interest rate environment, general economic conditions and circumstances specific to the issuer. Volatile market conditions may detrimentally affect the value of these securities, such as through reduced valuations due to the perception of heightened credit or liquidity risks. Changes in the value of these instruments may result in a reduction to earnings and/or capital, which may adversely affect our results of operations and financial condition.

Item 1A.  RISK FACTORS - continued
Risks Related to Our Business Strategy
Our strategy includes growth plans through organic growth and by means of acquisitions. Our financial condition and results of operations could be negatively affected if we fail to grow or fail to manage our growth effectively.
We intend to continue pursuing a growth strategy through organic growth and by means of acquisitions, both within our current footprint and through market expansion. We continue toalso actively evaluate acquisition opportunities as another source of growth. We cannot give assurance that we will be able to expand our existing market presence, or successfully enter new markets or that any such expansion will not adversely affect our results of operations. Failure to manage our growth effectively could have a material adverse effect on our business, future prospects, financial condition or results of operations and could adversely affect our ability to successfully implement our business strategy.
Our failure to find suitable acquisition candidates, or successfully bid against other competitors for acquisitions, could adversely affect our ability to fully implement our business strategy. If we are successful in acquiring other entities, the process of integrating such entities including Integrity Bancshares, Inc., will divert significant management time and resources. We may not be able to integrate efficiently or operate profitably Integrity Bancshares, Inc. or any other entity we may acquire. We may experience disruption and incur unexpected expenses in integrating acquisitions. These failures could adversely impact our future prospects and results of operation.
We are subject to competition from both banks and non-banking companies.
The financial services industry is highly competitive, and we encounter strong competition for deposits, loans and other financial services in our market area, including online providers of these projectsproducts and services. Our principal competitors include other local, regional and national financial services providers, such as other financial holding companies, commercial banks, of all types,credit unions, finance companies credit unions, mortgage brokers,and brokerage and insurance agencies, trust companiesfirms, including competitors that provide their products and various sellers of investments and investment advice.services online. Many of our non-bank competitors are not subject to the same degree

12


of regulation that we are and have advantages over us in providing certain services. Additionally, many of our competitors are significantly larger than we are and have greater access to capital and other resources. Failure to compete effectively for deposit, loan and other financial services customers in our markets could cause us to lose market share, slow our growth rate and have an adverse effect on our financial condition and results of operations.
We may be required to raise capital in the future, but that capital may not be available or may not be on acceptable terms when it is needed.
We are required by federal regulatory authorities to maintain adequate capital levels to support operations. New regulations to implement Basel III and the Dodd-Frank Act require us to have more capital. While we believe we currently have sufficient capital, if we cannot raise additional capital when needed, we may not be able to meet these requirements. AlsoIn addition, our ability to further expand our operations through organic growth, which includes growth within our current footprint and growth through market expansion, may be adversely affected.affected by any inability to raise necessary capital. Our ability to raise additional capital at any given time is dependent on capital market conditions at that time and on our financial performance and outlook.
Risks Related to Regulatory Compliance and Legal Matters
Legislation enacted in responseWe are subject to market and economic conditions may significantly affect our operations, financial condition and earnings.
The Dodd-Frank Act was enacted as a major reform in response to the financial crisis that began in the last decade. The Dodd-Frank Act increases regulation and oversight of the financial services industry, and imposes restrictions on the ability of institutions within the industry to conduct business consistent with historical practices, including aspects such as capital requirements, affiliate transactions, compensation, consumer protection regulations and mortgage regulation, among others. It is not clear what impact the Dodd-Frank Act and the numerous implementing regulations will ultimately have on the financial markets or on the U.S. banking and financial services industries and the broader U.S. and global economies. They may increase our costs of regulatory compliance and of doing business and otherwise affect our operations, and will likely result in additional costs and a diversion of management’s time from other business activities, any of which may adversely impact our results of operations, liquidity or financial condition. They also may significantly affect our business strategy, the markets in which we do business, the markets for and value of our investments and our ongoing operations, costs and profitability.
Futureextensive governmental regulation and legislation could limit our growth.supervision.
We are subject to extensive state and federal regulation, supervision and legislation that govern nearly every aspect of our operations. The regulations are primarily intended to protect depositors, customers and the banking system as a whole, not shareholders. These regulations affect our lending practices, capital structure, investment practices, dividend policy and growth, among other things. Congress and federal regulatory agencies continually review banking laws, regulations and policies for possible changes. The Dodd-Frank Act, enacted in July 2010, instituted major changes to the banking and financial institutions regulatory regimes. Other changes to statutes, regulations or policies could affect us in substantial and unpredictable ways. Such changes could subject us to additional costs of regulatory compliance and of doing business, limit the types of financial services and products we may offer and/or increase the ability of non-banks to offer competing financial services and products, among other things, and could divert management’s time from other business activities. Failure to comply with applicable laws, regulations, policies or supervisory guidance could lead to enforcement and other legal actions by federal or state authorities, including criminal or civil penalties, andthe loss of FDIC insurance, the revocation of a banking charter, other sanctions by regulatory agencies, and/or damage to our reputation. Furthermore, as shown through the Dodd-Frank Act, the regulatory environment is constantly undergoing change and the impact of changes to laws, the rapid implementation of regulations, the interpretation of such laws or regulations or other actions by existing or new regulatory agencies could make regulatory compliance more difficult or expensive, and thus could affect our ability to deliver or expand services, or it could diminish the value of our business. The ramifications and uncertainties of the recent increase inlevel of government intervention in the U.S. financial system could also adversely affect us. Refer

Item 1A.  RISK FACTORS - continued
Our controls and procedures may fail or be circumvented, which may result in a material adverse effect on our business, financial condition and results of operations.
Management regularly reviews and updates our internal controls, disclosure controls and procedures, and corporate governance policies and procedures. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of the controls and procedures or failure to Supervisioncomply with regulations related to controls and Regulation withinprocedures could have a material adverse effect on our business, results of operations and financial condition.
As previously disclosed in Part I,II, Item 19A “Controls and Procedures” of this Reportour Form 10-K for the period ended December 31, 2017, or Item 9A, a material weakness was identified in our internal control over financial reporting resulting from the inconsistent assessment of internally assigned risk weightings, which is one of several factors used to estimate the allowance for loan losses. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.
The material weakness did not result in any misstatement of our Consolidated Financial Statements for any period presented. As previously disclosed, we have provided additional information.training internally and improved our documentation to strengthen the support for the judgments applied to risk rating conclusions by our internal Loan Review Department. Additionally, an independent third-party completed an engagement that encompassed a review of our loan review policies, procedures and processes, as well as an in-depth examination of judgments supporting risk rating conclusions. Based on the remediation performed by us and the conclusions reached by the independent third-party. Management has concluded that the material weakness was remediated as of September 30, 2018. However, we may in the future discover areas of our internal controls that need improvement. Failure to maintain effective controls or to timely implement any necessary improvement of our internal and disclosure controls could, among other things, result in losses from errors, harm our reputation, or cause investors to lose confidence in the reported financial information, all of which could have a material adverse effect on our results of operations and financial condition.
Negative public opinion could damage our reputation and adversely impact our earnings and liquidity.
Reputational risk, or the risk to our business, earnings, liquidity and capital from negative public opinion, is inherent in our operations. Negative public opinion could result from our actual or alleged conduct in a variety of areas, including legal and regulatory compliance, lending practices, corporate governance, litigation, ethical issues or inadequate protection of customer information. Financial companies are highly vulnerable to reputational damage when they are found to have harmed customers, particularly retail customers, through conduct that is illegal or viewed as unfair, deceptive, manipulative or otherwise wrongful. We are dependent on third-party providers for a number of services that are important to our business. Refer to the risk factor titled, “We rely on third-party providers and other suppliers for a number of services that are important to our business. An interruption or cessation of an important service by any third partythird-party could have a material adverse effect on our business” for additional information. A failure by any of these third-party service providers could cause a disruption in our operations, which could result in negative public opinion about us or damage to our reputation. We expend significant resources to comply with regulatory requirements, and the failure to comply with such regulations could result in reputational harm or significant legal or remedial costs. Damage to our reputation could adversely affect our ability to retain and attract new customers and employees, expose us to litigation and regulatory action and adversely impact our earnings and liquidity.
We may be a defendant from time to time in a variety of litigation and other actions, which could have a material adverse effect on our financial condition and results of operations.

13


From time to time, customers and others make claims and take legal action pertaining to the performance of our responsibilities. Whether customer claims and legal action related to the performance of our responsibilities are founded or unfounded, if such claims and legal actions are not resolved in a manner favorable to us, they may result in significant expenses, attention from management and financial liability. Any financial liability or reputational damage could have a material adverse effect on our business, which, in turn, could have a material adverse effect on our financial condition and results of operations.

Item 1A.  RISK FACTORS - continued
Risks Related to Liquidity
We rely on a stable core deposit base as our primary source of liquidity.
We are dependent for our funding on a stable base of core deposits. Our ability to maintain a stable core deposit base is a function of our financial performance, our reputation and the security provided by FDIC insurance, which combined, gives customers confidence in us. If any of these items are damaged or come into question,considerations deteriorates, the stability of our core deposits could be harmed. In addition, deposit levels may be affected by factors such as general interest rate levels, rates paid by competitors, returns available to customers on alternative investments and general economic conditions. Accordingly, we may be required from time to time to rely on other sources of liquidity to meet withdrawal demands or otherwise fund operations.
Our ability to meet contingency funding needs, in the event of a crisis that causes a disruption to our core deposit base, is dependent on access to wholesale markets, including funds provided by the FHLB of Pittsburgh.
We own stock in the Federal Home Loan Bank of Pittsburgh, or FHLB, in order to qualify for membership in the FHLB system, which enables us to borrow on our line of credit with the FHLB that is secured by a blanket lien on a significant portion of our loan portfolio. Changes or disruptions to the FHLB or the FHLB system in general may materially impact our ability to meet short and long-term liquidity needs or meet growth plans. Additionally, we cannot be assured that the FHLB will be able to provide funding to us when needed, nor can we be certain that the FHLB will provide funds specifically to us, should our financial condition and/or our regulators prevent access to our line of credit. The inability to access this source of funds could have a materially adverse effect on our ability to meet our customer’s needs. Our financial flexibility could be severely constrained if we were unable to maintain our access to funding or if adequate financing is not available at acceptable interest rates.
Risks Related to Owning Our Stock
Our outstanding warrant may be dilutive to holders of our common stock.
The ownership interest of the existing holders of our common stock may be diluted to the extent our outstanding warrant is exercised. The warrant will remain outstanding until 2019. There are 517,012 shares of common stock underlying the warrant, representing approximately 1.46 percent of the shares of our common stock outstanding as of December 31, 2015 (including the shares issuable upon exercise of the warrant in total shares outstanding). The warrant holder has the right to vote any of the shares of common stock it receives upon exercise of the warrant.
Our ability to pay dividends on our common stock may be limited.
Holders of our common stock will be entitled to receive only such dividends as our Board of Directors may declare out of funds legally available for such payments. The payment of common dividends by S&T is subject to certain requirements and limitations of Pennsylvania law. Although we have historically declared cash dividends on our common stock, we are not required to do so and our Board of Directors could reduce, suspend or eliminate our dividend at any time. Substantial portions of our revenue consist of dividend payments we receive from S&T Bank. The payment of common dividends by S&T Bank is subject to certain requirements and limitations under federal and state laws and regulations that limit the amount of dividends it can pay to S&T. In addition, both S&T and S&T Bank are subject to various general regulatory policies relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. Any decrease to or elimination of the dividends on our common stock could adversely affect the market price of our common stock.

TableExplanation of ContentsUse of Non-GAAP Financial Measures
In addition to traditional measures presented in accordance with GAAP, our management uses, and this Report contains or references, certain non-GAAP financial measures identified below. We believe these non-GAAP financial measures provide information useful to investors in understanding our underlying operational performance and our business and performance trends as they facilitate comparisons with the performance of other companies in the financial services industry. Although we believe that these non-GAAP financial measures enhance investors’ understanding of our business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP or considered to be more important than financial results determined in accordance with GAAP, nor are they necessarily comparable with non-GAAP measures which may be presented by other companies.
We believe the presentation of net interest income on a FTE basis ensures comparability of net interest income arising from both taxable and tax-exempt sources and is consistent with industry practice. Interest income per the Consolidated Statements of Net Income is reconciled to net interest income adjusted to a FTE basis in Part II, Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" in this Report.
The efficiency ratio is noninterest expense divided by noninterest income plus net interest income, on a FTE basis, which ensures comparability of net interest income arising from both taxable and tax-exempt sources and is consistent with industry practice.

Item 6.  SELECTED FINANCIAL DATA --- continued

Common tangible book value, common return on average tangible common equity and the ratio of tangible common equity to tangible assets exclude goodwill and other intangible assets in order to show the significance of the tangible elements of our assets and common equity. Total assets and total average assets are reconciled to total tangible assets and total tangible average assets. Total shareholders' equity and total average shareholders' equity are also reconciled to total tangible common equity and total tangible average common equity. These measures are consistent with industry practice.

Item 6.  SELECTED FINANCIAL DATA - continued
On December 22, 2017, H.R.1, originally known as the Tax Cuts and Jobs Act, or Tax Act, was signed into law. We made certain tax adjustments to reflect the impact of the Tax Act in our 2017 income tax expense for the year ended December 31, 2017. An adjustment of $13.4 million was made for the re-measurement of our deferred tax assets and liabilities as a result of the new corporate rate of 21 percent, rather than the pre-enactment rate of 35 percent. We believe the $13.4 million non-cash tax expense impacts comparability to prior year financial measurements and results and therefore present certain non-GAAP financial measures excluding the impact of this amount. These non-GAAP measures exclude the net deferred tax asset, or DTA, re-measurement and are reconciled to the GAAP measures below:

Item 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
This section reviews our financial condition for each of the past two years and results of operations for each of the past three years. Certain reclassifications have been made to prior periods to place them on a basis comparable with the current period presentation. Some tables may include additional time periods to illustrate trends within our Consolidated Financial Statements. The results of operations reported in the accompanying Consolidated Financial Statements are not necessarily indicative of results to be expected in future periods.

Important Note Regarding Forward-Looking Statements
19This Annual Report on Form 10-K contains or incorporates statements that we believe are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally relate to our financial condition, results of operations, plans, objectives, outlook for earnings, revenues, expenses, capital and liquidity levels and ratios, asset levels, asset quality, financial position, and other matters regarding or affecting S&T and its future business and operations. Forward looking statements are typically identified by words or phrases such as “will likely result”, “expect”, “anticipate”, “estimate”, “forecast”, “project”, “intend”, “ believe”, “assume”, “strategy”, “trend”, “plan”, “outlook”, “outcome”, “continue”, “remain”, “potential”, “opportunity”, “believe”, “comfortable”, “current”, “position”, “maintain”, “sustain”, “seek”, “achieve” and variations of such words and similar expressions, or future or conditional verbs such as will, would, should, could or may. Although we believe the assumptions upon which these forward-looking statements are based are reasonable, any of these assumptions could prove to be inaccurate and the forward-looking statements based on these assumptions could be incorrect. The matters discussed in these forward-looking statements are subject to various risks, uncertainties and other factors that could cause actual results and trends to differ materially from those made, projected, or implied in or by the forward-looking statements depending on a variety of uncertainties or other factors including, but not limited to: credit losses; cyber-security concerns; rapid technological developments and changes; sensitivity to the interest rate environment including a prolonged period of low interest rates, a rapid increase in interest rates or a change in the shape of the yield curve; a change in spreads on interest-earning assets and interest-bearing liabilities; regulatory supervision and oversight; legislation affecting the financial services industry as a whole, and S&T, in particular; the outcome of pending and future litigation and governmental proceedings; increasing price and product/service competition; the ability to continue to introduce competitive new products and services on a timely, cost-effective basis; managing our internal growth and acquisitions; the possibility that the anticipated benefits from acquisitions cannot be fully realized in a timely manner or at all, or that integrating the acquired operations will be more difficult, disruptive or costly than anticipated; containing costs and expenses; reliance on significant customer relationships; general economic or business conditions; deterioration of the housing market and reduced demand for mortgages; deterioration in the overall macroeconomic conditions or the state of the banking industry that could warrant further analysis of the carrying value of goodwill and could result in an adjustment to its carrying value resulting in a non-cash charge to net income; re-emergence of turbulence in significant portions of the global financial and real estate markets that could impact our performance, both directly, by affecting our revenues and the value of our assets and liabilities, and indirectly, by affecting the economy generally and access to capital in the amounts, at the times and on the terms required to support our future businesses. Many of these factors, as well as other factors, are described elsewhere in this report, including Part I, Item 1A, Risk Factors and any of our subsequent filings with the SEC. Forward-looking statements are based on beliefs and assumptions using information available at the time the statements are made. We caution you not to unduly rely on forward-looking statements because the assumptions, beliefs, expectations and projections about future events may, and often do, differ materially from actual results. Any forward-looking statement speaks only as to the date on which it is made, and we undertake no obligation to update any forward-looking statement to reflect developments occurring after the statement is made.

Important Note Regarding Forward-Looking Statements
This Annual Report on Form 10-K contains or incorporates statements that we believe are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These statements generally relate to our financial condition, results of operations, plans, objectives, future performance or business. They usually can be identified by the use of forward-looking language such as “will likely result,” “may,” “are expected to,” “is anticipated,” “estimate,” “forecast,” “projected,” “intends to” or other similar words. You should not place undue reliance on these statements, as they are subject to risks and uncertainties, including but not limited to, those identified under Risk Factors in Part I, Item 1A of this Report, the documents incorporated by reference or other important factors disclosed in this Report and from time to time in our other filings with the Securities and Exchange Commission, or SEC. When considering these forward-looking statements, you should keep in mind these risks and uncertainties, as well as any cautionary statements we may make. Moreover, you should treat these statements as speaking only as of the date they are made and based only on information actually known to us at that time. We undertake no obligation to update publicly any forward-looking statements, whether as a result of new information, future events or otherwise.
These forward-looking statements are based on current expectations, estimates and projections about our business and beliefs and assumptions made by management. These Future Factors are not guarantees of our future performance and involve certain risks, uncertainties and assumptions, which are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or forecasted in these forward-looking statements.
Future Factors include:
credit losses;
cyber-security concerns, including an interruption or breach in the security of our information systems;
rapid technological developments and changes;
sensitivity to the interest rate environment including a prolonged period of low interest rates, a rapid increase in interest rates or a change in the shape of the yield curve;
a change in spreads on interest-earning assets and interest-bearing liabilities;
regulatory supervision and oversight, including Basel III required capital levels, and public policy changes, including environmental regulations;
legislation affecting the financial services industry as a whole, and S&T, in particular, including the effects of the Dodd-Frank Act;
the outcome of pending and future litigation and governmental proceedings;
increasing price and product/service competition, including new entrants;
the ability to continue to introduce competitive new products and services on a timely, cost-effective basis;
managing our internal growth and acquisitions, particularly our recent acquisition of Integrity Bancshares, Inc., or Integrity;
the possibility that the anticipated benefits from the recent Integrity acquisition and any other future acquisitions cannot be fully realized in a timely manner or at all, or that integrating the operations of Integrity or future acquired operations will be more difficult, disruptive or costly than anticipated;
containing costs and expenses;
reliance on significant customer relationships;
general economic or business conditions, either nationally or regionally in our market areas, may be less favorable than expected, resulting in among other things, a reduced demand for credit and other services;
deterioration of the housing market and reduced demand for mortgages;
a deterioration in the overall macroeconomic conditions or the state of the banking industry that could warrant further analysis of the carrying value of goodwill and could result in an adjustment to its carrying value resulting in a non-cash charge to net income;
a re-emergence of turbulence in significant portions of the global financial and real estate markets that could impact our performance, both directly, by affecting our revenues and the value of our assets and liabilities, and indirectly, by affecting the economy generally; and
access to capital in the amounts, at the times and on the terms required to support our future businesses.
These are representative of the Future Factors that could affect the outcome of the forward-looking statements. In addition, such statements could be affected by general industry and market conditions and growth rates, general economic conditions, including interest rate fluctuations, and other Future Factors.

Critical Accounting Policies and Estimates
Our Consolidated Financial Statements are prepared in accordance with U.S. generally accepted accounting principles, or GAAP. Application of these principles requires management to make estimates, assumptions and judgments that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes. These estimates, assumptions and judgments are based on information available as of the date of the Consolidated Financial Statements; accordingly, as this information changes, the Consolidated Financial Statements could reflect different estimates, assumptions and judgments. Certain policies are based to a greater extent on estimates, assumptions and judgments of management and, as such, have a greater possibility of producing results that could be materially different than originally reported.
Our most significant accounting policies are presented in Part II, Item 8, Note 1 Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Report. These policies, along with the disclosures presented in the Notes to Consolidated Financial Statements, provide information on how significant assets and liabilities are valued in the Consolidated Financial Statements and how those values are determined.
We view critical accounting policies to be those which are highly dependent on subjective or complex estimates, assumptions and judgments and where changes in those estimates and assumptions could have a significant impact on the Consolidated Financial Statements. We currently view the determination of the allowance for loan losses, or ALL income taxes, securities valuation and goodwill and other intangible assets to be critical accounting policies. During 2015,2018, we did not significantly change the manner in which we applied our critical accounting policies or developed related assumptions or estimates. We have reviewed these critical accounting estimates and related disclosures with the Audit Committee.
Allowance for Loan Losses
Our loan portfolio is our largest category of assets on our Consolidated Balance Sheets. We have designed a systematic ALL methodology which is used to determine our provision for loan losses and ALL on a quarterly basis. The ALL represents management’s estimate of probable losses inherent in the loan portfolio at the balance sheet date and is presented as a reserve against loans in the Consolidated Balance Sheets. The ALL is increased by a provision charged to expense and reduced by charge-offs, net of recoveries. Determination of an adequate ALL is inherently subjective and may be subject to significant changes from period to period.
The methodology for determining the ALL has two main components: evaluation and impairment tests of individual loans and evaluation and impairment tests of certain groups of homogeneous loans with similar risk characteristics.
We individually evaluate all substandard and nonaccrual commercial loans greater than $0.5 million for impairment. A loan is considered to be impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the original contractual terms of the loan agreement. For all troubled debt restructurings, or TDRs, regardless of size, as well as all other impaired loans, we conduct further analysis to determine the probable loss and assign a specific reserve to the loan if deemed appropriate. Specific reserves are established based upon the following three impairment methods: 1) the present value of expected future cash flows discounted at the loan’s effective interest rate, 2) the loan’s observable market price or 3) the estimated fair value of the collateral if the loan is collateral dependent. These analyses involve a high degree of judgment in estimating the amount of loss associated with specific impaired loans, including estimating the amount and timing of future cash flows, the current estimated fair value of the loan and collateral values. Our impairment evaluations consist primarily of the fair value of collateral method because most of our loans are collateral dependent. We obtain appraisals annually on impaired loans greater than $0.5 million.
The ALL methodology for groups of homogeneous loans, or the reserve for loans collectively evaluated for impairment, is comprised of both a quantitative and qualitative analysis. We first apply historical loss rates to pools of loans, with similar risk characteristics, using a migration analysis where losses in each pool are aggregated over the loss emergence period, or LEP. The LEP is an estimate of the average amount of time from when an event happens that causes the borrower to be unable to pay on a loan until the loss is confirmed through a loan charge-off.
In conjunction with our annual review of the ALL assumptions, we have updated our analysis of LEPs for our Commercial and Consumer loan portfolio segments using our loan charge-off history. The analysis showed that theNo changes were made to our LEP for our Commercial and Industrial, or C&I, has shortened and our Commercial Real Estate, or CRE, and Commercial Construction portfolio segments have not changed.assumptions in 2018. We estimate thean LEP to be 2of 3 years for C&I, compared to 2.5 years in the prior year, and 3.5CRE, 4 years for both CREconstruction and Commercial Construction. Our analysis showed1.25 years for C&I. We estimate an LEP of 2.75 years for Consumer Real Estate of 3.5 years and Other Consumer of 1.25 years. This compares to 2 years for both Consumer Real Estate and Other Consumer in the prior year when peer data was being utilized to estimate the LEP. We believe that our actual experience captured through our internal analysis better reflects the inherent risk in these portfolios compared to the peer data used in prior years.Consumer.
Another key assumption is the look-back period, or LBP, which represents the historical data period utilized to calculate loss rates. We lengthened the LBP for all Commercial and Consumer portfolio segments in order to capture relevant historical

21


Item 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS -- continued


data believed to be reflective of losses inherent in the portfolios. We use 6.5used 9.5 years for our LBP for all portfolio segments which encompasses our loss experience during the Great Recession2008 - 2010 Financial Crisis, and our more recent improved loss experience.
After consideration of the historic loss calculations, management applies additional qualitative adjustments so that the ALL is reflective of the inherent losses that exist in the loan portfolio at the balance sheet date. Qualitative adjustments are made based upon changes in lending policies and practices, economic conditions, changes in the loan portfolio, changes in lending management, results of internal loan reviews, asset quality trends, collateral values, concentrations of credit risk and other external factors. The evaluation of the various components of the ALL requires considerable judgment in order to estimate inherent loss exposures.
The changes made to the ALL assumptions were applied prospectively and did not result in a material change to the total ALL. Lengthening the LBP does increase the historical loss rates and therefore the quantitative component of the ALL. We believe this makes the quantitative component of the ALL more reflective of inherent losses that exist within the loan portfolio, which resulted in a decrease in the qualitative component of the ALL. 
Acquired loans are recorded at fair value on the date of acquisition with no carryover of the related ALL. Determining the fair value of the acquired loans involves estimating the principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. In estimating the fair value of our acquired loans, we considered a number of factors including the loan term, internal risk rating, delinquency status, prepayment rates, recovery periods, estimated value of the underlying collateral and the current interest rate environment.

Item 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued


Loans acquired with evidence of credit deterioration were evaluated and not considered to be significant. The premium or discount estimated through the loan fair value calculation is recognized into interest income on a level yield or straight-line basis over the remaining contractual life of the loans. Additional credit deterioration on acquired loans, in excess of the original credit discount embedded in the fair value determination on the date of acquisition, will be recognized in the ALL through the provision for loan losses.
Our ALL Committee meets at least quarterly to verify the overall adequacy of the ALL. Additionally, on an annual basis, the ALL Committee meets to validate our ALL methodology. This validation includes reviewing the loan segmentation, LEP, LBP and the qualitative framework. As a result of this ongoing monitoring process, we may make changes to our ALL to be responsive to the economic environment.
Although we believe our process for determining the ALL adequately considers all of the factors that would likely result in credit losses, the process includes subjective elements and may be susceptible to significant change. To the extent actual losses are higher than management estimates, additional provisions for loan losses could be required and could adversely affect our earnings or financial position in future periods.
Income Taxes
We estimate income tax expense based on amounts expected to be owed to the tax jurisdictions where we conduct business. The laws are complex and subject to different interpretations by us and various taxing authorities. On a quarterly basis, we assess the reasonableness of our effective tax rate based upon our current estimate of the amount and components of pre-tax income, tax credits and the applicable statutory tax rates expected for the full year.
We determine deferred income tax assets and liabilities using the asset and liability method, and we report them in other assets or other liabilities, as appropriate, in the Consolidated Balance Sheets. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities and recognizes enacted changes in tax rate and laws. When deferred tax assets are recognized, they are subject to a valuation allowance based on management’s judgment as to whether realization is more likely than not.
Accrued taxes represent the net estimated amount due to taxing jurisdictions and are reported in other assets or other liabilities, as appropriate, in the Consolidated Balance Sheets. We evaluate and assess the relative risks and appropriate tax treatment of transactions and filing positions after considering statutes, regulations, judicial precedent and other information and maintain tax accruals consistent with the evaluation of these relative risks and merits. Changes to the estimate of accrued taxes occur periodically due to changes in tax rates, interpretations of tax laws, the status of examinations being conducted by taxing authorities and changes to statutory, judicial and regulatory guidance. These changes, when they occur, can affect deferred taxes and accrued taxes, as well as the current period’s income tax expense and can be significant to our operating results.
Tax positions are recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50 percent likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.

Item 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS -- continued


Securities Valuation
We determine the appropriate classification of securities at the time of purchase. All securities, including both debt and equity securities, are classified as available-for-sale. These securities are carried at fair value with net unrealized gains and losses deemed to be temporary and are reported separately as a component of other comprehensive income (loss), net of tax. We obtain fair values for debt securities from a third-party pricing service which utilizes several sources for valuing fixed-income securities. We validate prices received from our pricing service through comparison to a secondary pricing service and broker quotes. We review the methodologies of the pricing service which provides us with a sufficient understanding of the valuation models, assumptions, inputs and pricing to reasonably measure the fair value of our debt securities. Realized gains and losses on the sale of available-for-sale securities and other-than-temporary impairment, or OTTI, charges are recorded within noninterest income in the Consolidated Statements of Net Income. Realized gains and losses on the sale of securities are determined using the specific-identification method.
We perform a quarterly review of our securities to identify those that may indicate an OTTI. Our policy for OTTI within the marketable equity securities portfolio generally requires an impairment charge when the security is in a loss position for 12 consecutive months, unless facts and circumstances would suggest the need for an OTTI prior to that time. Our policy for OTTI within the debt securities portfolio is based upon a number of factors, including but not limited to, the length of time and extent to which the estimated fair value has been less than cost, the financial condition of the underlying issuer, the ability of the issuer to meet contractual obligations, the likelihood of the security’s ability to recover any decline in its estimated fair value and whether we intend to sell the investment security or if it is more likely than not that we will be required to sell the security prior to the security’s recovery. If the impairment is considered other-than-temporary based on management’s review, the impairment must be separated into credit and non-credit portions. The credit component is recognized in the Consolidated Statements of Net Income and the non-credit component is recognized in other comprehensive income (loss), net of applicable taxes. If the financial markets experience deterioration, charges to income could occur in future periods.
Goodwill and Other Intangible Assets
As a result of acquisitions, we have recorded goodwill and identifiable intangible assets in our Consolidated Balance Sheets. Goodwill represents the excess of the purchase price over the fair value of net assets acquired. We account for business combinations using the acquisition method of accounting.
GoodwillWe have three reporting units: Community Banking, Insurance and Wealth Management. Existing goodwill relates to value inherent in the Community Banking and Insurance reporting unitsunit and that value is dependent upon our ability to provide quality, cost-effective services in the face of competition from other market participants. This ability relies upon continuing investments in processing systems, the development of value-added service features and the ease of use of our services. As such, goodwill value is supported ultimately by profitability that is driven by the volume of business transacted. A decline in earnings as a result of a lack of growth or the inability to deliver cost-effective services over sustained periods can lead to impairment of goodwill, which could adversely impact our earnings in future periods.periods
We have three reporting units: Community Banking, Insurance and Wealth Management. The carrying value of goodwill is tested annually for impairment each October 1st or more frequently if it is determined that a triggering event has occurred. We first assess qualitatively whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Our qualitative assessment considers such factors as macroeconomic conditions, market conditions specifically related to the banking industry, our overall financial performance and various other factors. If we determine that it is more likely than not that the fair value is less than the carrying amount, we proceed to test for impairment. The evaluation for impairment involves comparing the current estimated fair value of each reporting unit to its carrying value, including goodwill. If the current estimated fair value of a reporting unit exceeds its carrying value, no additional testing is required and an impairment loss is not recorded. If the estimated fair value of a reporting unit is less than the carrying value, further valuation procedures are performed that could result in impairment of goodwill being recorded. Further valuation procedures would include allocating the estimated fair value to all assets and liabilities of the reporting unit to determine an implied goodwill value. If the implied value of goodwill of a reporting unit is less than the carrying amount of that goodwill, an impairment loss is recognized in an amount equal to that excess. We completed the annual goodwill impairment assessment as required in 2015, 20142018, 2017 and 2013;2016; the results indicated that the fair value of each reporting unit exceeded the carrying value.
Based upon our qualitative assessment performed for our annual impairment analysis, we concluded that it is more likely than not that the fair value of the reporting units exceeds the carrying value. Both the national economy and the local economies in our markets have shown improvement over the past couple of years. General economic activity and key indicators such as housing and unemployment continue to show improvement. While still challenging, the banking environment continues to improve with better asset quality, improved earnings and generally better stock prices. Activity in mergers and acquisitions demonstrated that there is premium value on banking franchises and a number of banks of our size have been able to access the capital markets over the past year. Our stock traded significantly above book value throughout 2015. Although our stock price has declined in 2016, the decline has been consistent with the overall decline in bank stocks and our stock price continues to

23


Item 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS -- continued


trade in excess of our book value per share. Additionally, our overall performance remains strong, and we have not identified any other facts or circumstances that would cause us to conclude that it is more likely than not that the fair value of each of the reporting units would be less than the carrying value of the reporting unit.
We determine the amount of identifiable intangible assets based upon independent core deposit and insurance contract valuations at the time of acquisition. Intangible assets with finite useful lives, consisting primarily of core deposit and customer list intangibles, are amortized using straight-line or accelerated methods over their estimated weighted average useful lives, ranging from 10 to 20 years. Intangible assets with finite useful lives are evaluated for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. No such events or changes in circumstances occurred during the years ended December 31, 2015, 20142018, 2017 and 2013.2016.
The financial services industry and securities markets can be adversely affected by declining values. If economic conditions result in a prolonged period of economic weakness in the future, our business segments, including the Community Banking segment, may be adversely affected. In the event that we determine that either our goodwill or finite lived intangible assets areis impaired, recognition of an impairment charge could have a significant adverse impact on our financial position or results of operations in the period in which the impairment occurs.

Recent Accounting Pronouncements and Developments
Note 1 Summary of Significant Accounting Policies in the Notes to the Consolidated Financial Statements, which is included in Part II, Item 8 of this Report, discusses new accounting pronouncements that we have adopted and the expected impact of accounting pronouncements recently issued or proposed, but not yet required to be adopted.
Executive Overview
We are a bank holding company headquartered in Indiana, Pennsylvania with assets of $6.3 billion at December 31, 2015. We operate locations in Pennsylvania, Ohio and New York. We provide a full range of financial services with retail and commercial banking products, cash management services, insurance and trust and brokerage services. Our common stock trades on the NASDAQ Global Select Market under the symbol “STBA.”
We earn revenue primarily from interest on loans and securities and fees charged for financial services provided to our customers. Offsetting these revenues are the cost of deposits and other funding sources, provision for loan losses and other operating costs such as salaries and employee benefits, data processing, occupancy and tax expense.
Our mission is to become the financial services provider of choice within the markets that we serve. We strive to do this by delivering exceptional service and value, one customer at a time. Our strategic plan focuses on organic growth, which includes growth within our current footprint and growth through market expansion. We also actively evaluate acquisition opportunities as another source of growth. Our strategic plan includes a collaborative model that combines expertise from all of our business segments and focuses on satisfying each customer’s individual financial objectives.
Our major accomplishments during 2015 included:
Our 2015 net income increased $9.2 million, or 15.8 percent, to a record $67.1 million, or $1.98 per diluted share, compared to $57.9 million, or $1.95 per diluted share for 2014. Return on average assets was 1.13 percent and return on average equity was 8.94 percent for 2015.
On March 4, 2015, we completed a merger with Integrity, or the Merger, which expanded our geographic footprint into south-central Pennsylvania with eight branches in Cumberland, Dauphin, Lancaster and York Counties. The transaction was valued at $172.0 million and added total assets of $980.8 million, including $788.7 million in loans, $115.9 million in goodwill, and $722.3 million in deposits. Integrity Bank became a separate subsidiary of S&T upon completion of the Merger and was subsequently merged into S&T Bank on May 8, 2015.
During 2015, we successfully executed on our organic growth strategy in our current footprint and by expanding into new markets. On March 23, 2015, we expanded our commercial banking operations by opening a loan production office, or LPO, in western New York. We had organic loan growth of $370.2 million during 2015.
We opened two new branch innovation centers in 2015. On March 9, 2015, we opened the Indian Springs branch and on August 17, 2015 we opened the McCandless Crossings branch. Both branches feature a "tech bar" where customers can check their accounts on tablets, in-branch Wi-Fi and a configuration that replaces teller lines with pods where customers sit down with bank representatives to discuss services beyond traditional banking needs.
We remain focused on running our business efficiently. During 2015, we had positive operating leverage with total revenue growth of $44.2 million, or 23 percent, while operating expenses increased $19.5 million, or 17 percent compared to 2014.
Our focus continues to be on loan and deposit growth and implementing opportunities to increase fee income while maintaining a strong expense discipline. With our recent expansion into new markets, we are focused on executing our strategy to successfully build our brand and grow our business in these markets. The low interest rate environment remains a challenge for our net interest income, but our organic growth will help to mitigate the impact.

Executive Overview
We are a $7.3 billion bank holding company that is headquartered in Indiana, Pennsylvania and trades on the NASDAQ Global Select Market under the symbol STBA. Our principal subsidiary, S&T Bank, a full-service financial institution, was established in 1902, and operates in five markets including Western Pennsylvania, Central Pennsylvania, Northeast Ohio, Central Ohio, and Upstate New York. We employ a geographic market based strategy in order to drive organic growth. Each of our five markets is lead by a Market President who is responsible for developing strategic initiatives specific to each market. We acknowledge that each of our five markets are in different stages of development and that our market based strategy will allow us to customize our approach to each market given its developmental stage and unique characteristics. We provide a full range of financial services with retail and commercial banking products, cash management services, trust and brokerage services.
We earn revenue primarily from interest on loans and securities and fees charged for financial services provided to our customers. We incur expenses for the cost of deposits and other funding sources, provision for loan losses and other operating costs such as salaries and employee benefits, data processing, occupancy and tax expense.
Our mission is to become the financial services provider of choice within the markets that we serve. We strive to do this by delivering exceptional service and value, one customer at a time. Our strategic plan focuses on organic growth, which includes both growth within our current footprint and growth through market expansion. We also actively evaluate acquisition opportunities as another source of growth. Our strategic plan includes a collaborative model that combines expertise from all areas of our business and focuses on satisfying each customer’s individual financial objectives.
Our major accomplishments during 2018 included:
We had record net income for 2018 of $105.3 million, or $3.01 per diluted share, surpassing our 2017 net income of $73.0 million, or $2.09 per diluted share.
Return on average assets was 1.50 percent, return on average equity was 11.60 percent and return on tangible shareholders' equity (non-GAAP) was 17.14 percent for 2018.
Net interest income increased $8.7 million, or 3.9 percent, and net interest margin (FTE) (non-GAAP) increased eight basis points to 3.64 percent compared to 3.56 percent in 2017.
Our expenses were well controlled during 2018 with an improved efficiency ratio (non-GAAP) of 50.60 percent compared to 51.77 percent for 2017.
We were recognized by Forbes as one of the Best-In-State Banks and Credit Unions, naming S&T Bank as the second highest-rated bank in Pennsylvania – further confirming our ability to fulfill our mission of creating value for our customers and shareholders through consistent and outstanding financial performance.
Our focus continues to be on organic loan and deposit growth and implementing opportunities to increase fee income while closely monitoring our operating expenses and asset quality. We are focused on executing our strategy to successfully build our brand and grow our business in all of our markets. We have benefited from recent increases in short-term interest rates from the Tax Cuts and Jobs Act (Tax Act) which lowered the federal corporate tax rate from 35 percent to 21 percent effective January 1, 2018.
On November 9, 2017, we entered into an asset purchase agreement to sell a 70 percent ownership interest in the assets of our subsidiary, S&T Evergreen Insurance, LLC. At the date of the sale, January 1, 2018, we ceased to have a controlling financial interest, therefore we deconsolidated the subsidiary and recognized a gain of $1.9 million. We transferred our remaining 30 percent share of net assets from S&T Evergreen Insurance, LLC to a new entity for a 30 percent partnership interest in a new insurance entity.
Return on tangible shareholders' equity and the efficiency ratio are non-GAAP measures. Refer to Explanation of Use of Non-GAAP Financial Measures in Part II, Item 6 Selected Financial Data of this Report for a reconciliation to the most directly comparable GAAP measures. Net interest margin (FTE) is a non-GAAP measure and is reconciled to the comparable GAAP measure in the "Net Interest Income" section of this Management's Discussion and Analysis of Financial Condition and Results of Operations, or MD&A, below.

Excluding the net DTA re-measurement, net income was $86.4 million (non-GAAP) and diluted earnings per share in 2015 compared to $57.9 million or $1.95was $2.47 (non-GAAP). Net income and diluted earnings per share adjusted to exclude the net DTA remeasurement are non-GAAP measures. Refer to Explanation of Use of

The increase in net income was primarily due to decreases in the provision for income taxes of $28.6 million and noninterest expense of $2.5 million, an increase in net interest income of $39.5$8.7 million or 27 percent, and noninterest income of $4.7 million, or 10 percent partially offset by increasesa decrease of $6.3 million in our provision for loan losses of $8.7 million, noninterest expenses of $19.5 million and our provision for income taxes of $6.9 million. Noninterest expense included $3.2 million of merger related expenses during the year ended December 31, 2015.income.
Net interest income increased $39.5$8.7 million, or 273.9 percent, to $187.6$234.4 million compared to $148.0$225.7 million in 2014. The increase was primarily2017. Average interest-earning assets were unchanged from 2017 at $6.5 billion. Average interest-bearing liabilities decreased $115.6 million due to the increase in average interest-earning assets of $1.0 billion, or 24 percent, partially offset by an increasedecreases in average interest-bearing liabilities of $887deposits and short-term borrowings. Average interest-bearing deposits decreased $25.1 million or 29 percent, compared to 2014. The increase inand average interest-earning assets related to the Merger and our successful efforts in growing our loan portfolio organically during 2015. Net interest income was favorably impacted by accretion resulting from purchase accounting fair value adjustments related to the Merger of $6.2short-term borrowings decreased $119.7 million for 2015.2018. Net interest margin, on a fully taxable-equivalent, or FTE, basis (non-GAAP), increased eight basis points to 3.64 percent in 2018 compared to 3.56 percent for 2017. The increases in 2015 comparedshort-term interest rates over the past year positively impacted both net interest income and net interest margin. Net interest margin is reconciled to 3.50 percent for 2014.net interest income adjusted to a FTE basis below in the "Net Interest Income" section of this MD&A.
The provision for loan losses increased $8.7$1.1 million, or 8.0 percent, to $10.4$15.0 million during 20152018 compared to $1.7$13.9 million in 2014.2017. The higher provision for loan losses wasincreased due to increases in substandard loans and impaired loans with specific reserves. Commercial substandard loans increased $110.5 million to $181.2 million at December 31, 2018 compared to $70.7 million at December 31, 2017. The increase in substandard loans from December 31, 2017 was mainly due to the receipt of updated financial information from our borrowers that resulted in the loans being downgraded. Impaired loans increased $22.7 million with an increase in net loan charge-offs.specific reserves of $1.7 million compared to 2017. Net loan charge-offs were $10.2consistent at $10.4 million, or 0.220.18 percent of average loans, for 20152018 compared to only $0.1$10.3 million, or 0.000.18 percent of average loans, in 2014. During 2014, our net loan charge-offs and other asset quality metrics were at historically low levels resulting in an unusually low provision for loan losses.2017.
Total noninterest income increased $4.7decreased $6.3 million or 10 percent, to $51.0$49.2 million for 2015 compared to $46.3$55.5 million for 2014. The increase was primarilyin 2017. Insurance income decreased $4.9 million compared to 2017 due to additionalthe sale of a majority interest in our insurance business on January 1, 2018. A gain of $1.9 million was recognized in 2018 related to this sale. Further decreasing noninterest income aswere security gains of $3.0 million recognized in 2017 compared to no gains in 2018. Other income decreased $1.7 million due to a resultbank owned life insurance, or BOLI, claim of the Merger, including higher mortgage banking income.$0.7 million and a $1.0 million gain on a branch sale both during 2017.
Expenses were well controlled during 2018. Total noninterest expense increased $19.5decreased $2.5 million to $136.7$145.4 million for 20152018 compared to $117.2$147.9 million for 2014. Salaries2017. The decrease was mainly due to a decrease in salaries and employee benefits increased $7.8of $4.7 million during 2015 primarily due to additionallower incentives and commission costs and fewer employees annual merit increases and higher pension and incentive expense. Additional increases were due to higher operating expenses resulting from the Mergersale of our insurance business on January 1, 2018. FDIC insurance decreased $1.3 million due to improvements in the components used to determine the assessment. Offsetting these improvements was an increase of $1.7 million for other taxes related to a state sales tax assessment. Data processing and $3.2information technology, or IT, increased $1.8 million mainly due to a recent outsourcing arrangement for certain components of merger related expenses.our IT function.
The provision for income taxes increased $6.9decreased $28.6 million to $24.4$17.8 million compared to $17.5$46.4 million in 2014.2017. Our effective tax rate was 14.5 percent for 2018 compared to 38.9 percent for 2017. The increasedecrease was primarily due to a $16.1the enactment of the Tax Act which lowered the federal corporate tax rate from 35 percent to 21 percent effective January 1, 2018. The comparison between the 2018 and the 2017 tax provision was also affected by the increased tax expense in 2017 for the non-cash tax adjustment of $13.4 million increase in pretax income.for the re-measurement of our deferred tax assets and liabilities.
Net Interest Income
Our principal source of revenue is net interest income. Net interest income represents the difference between the interest and fees earned on interest-earning assets and the interest paid on interest-bearing liabilities. Net interest income is affected by changes in the average balance of interest-earning assets and interest-bearing liabilities and changes in interest rates and spreads.Maintaining consistent spreads between interest-earning assets and interest-bearing liabilities is significant to our financial performance because net interest income comprised 79 percent of operating revenue (net interest income plus noninterest income, excluding security gains/losses and non-recurring income and expenses) in 2015 and 76 percent of operating revenue in 2014. Refer to page 48 Explanation of Use of Non-GAAP Financial Measures for a discussion of operating revenue as a non-GAAP financial measure. The level and mix of interest-earning assets and interest-bearing liabilities is managed by our Asset and Liability Committee, or ALCO, in order to mitigate interest rate and liquidity risks of the balance sheet. A variety of ALCO strategies were implemented, within prescribed ALCO risk parameters, to produce what we believe is an acceptable level of net interest income.
The interest income on interest-earning assets and the net interest margin are presented on a FTE basis. The FTE basis adjusts for the tax benefit of income on certain tax-exempt loans and securities and the dividend-received deduction for equity securities using the federal statutory tax rate of 21 percent for 2018 and 35 percent for 2017 and 2016. We believe this to be the preferred industry measurement of net interest income that provides a relevant comparison between taxable and non-taxable sources of interest income.

(1)Nonaccruing loans are included in the daily average loan amounts outstanding.
(2)Tax-exempt income is on a FTE basis using the statutory federal corporate income tax rate of 21 percent for 2018 and 35 percent for 2017 and 2016.
(3)Taxable investment income is adjusted for the dividend-received deduction for equity securities.
(4)Changes to rate/volume are allocated to both rate and volume on a proportionate dollar basis.
Net interest income on a FTE basis increased $5.0 million, or 2.2 percent, compared to 2017. The net interest margin on a FTE basis increased eight basis points compared to 2017. These increases were primarily due to higher short-term interest rates offset by the decrease in the federal corporate tax rate effective January 1, 2018, which negatively impacted the net interest margin on a FTE basis by six basis points or $3.0 million, compared to 2017.
Interest income on a FTE basis increased $25.5 million, or 9.5 percent, compared to 2017. The increase was primarily due to higher short-term interest rates. Average interest-bearing deposits with banks, which is primarily cash at the Federal Reserve, remained relatively flat and the average rate earned increased 82 basis points due to higher short-term interest rates. Average securities decreased $15.7 million due to a decline in the market value of our bond portfolio and the average rate earned increased 14 basis points. Average loan balances increased $17.2 million and the average rate earned on loans increased 40 basis points due to higher short-term interest rates. The average rate earned on the FHLB and other restricted stock improved due to an increase in the FHLB’s quarterly dividend in 2018. Overall, the FTE rate on interest-earning assets increased 39 basis points compared to 2017.

Item 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued


Interest expense increased $20.5 million compared to 2017. The increase was primarily due to higher short-term interest rates. Average interest-bearing deposits decreased $25.1 million. Average money market balances increased $304.4 million and the average rate paid increased 61 basis points due to higher short-term interest rates. The increase in average money market balances was partially attributable to a shift in deposit mix with decreases in average interest-bearing demand, savings, and certificates of deposit balances. The overall decline in interest-bearing deposits is favorably offset by increased average noninterest-bearing demand balances of $65.5 million. Average borrowings decreased $90.4 million. Short-term borrowings decreased $119.7 million and the average rate paid increased 96 basis points due to higher short-term interest rates. Long-term borrowings increased $29.9 million and the average rate paid decreased 22 basis points due to the addition of a long-term variable rate borrowing in November 2017. Overall, the cost of interest-bearing liabilities increased 46 basis points compared to 2017.
Provision for Loan Losses
The provision for loan losses is the adjustment to the ALL after net loan charge-offs have been deducted to bring the ALL to a level determined to be adequate to absorb probable losses inherent in the loan portfolio. The provision for loan losses increased $1.1 million, or 8.0 percent, to $15.0 million for 2018 compared to $13.9 million for 2017. The provision for loan losses increased primarily due to increases in substandard loans and impaired loans with specific reserves.
Commercial special mention and substandard loans increased $67.7 million to $268.5 million compared to $200.8 million at December 31, 2017, with an increase of $110.5 million in substandard offset by a decrease of $42.8 million in special mention. The increase in substandard loans from December 31, 2017 was mainly due to the receipt of updated financial information from our borrowers that resulted in the loans being downgraded.
Impaired loan balances increased $22.7 million, or 84.6 percent, to $49.5 million at December 31, 2018 compared to $26.8 million at December 31, 2017 with an increase in specific reserves of $1.7 million compared to December 31, 2017. The increase in specific reserves related to an $11.3 million commercial construction loan that had a specific reserve of $1.3 million at December 31, 2018.
Net charge-offs increased $0.1 million to $10.4 million, or 0.18 percent of average loans in 2018, compared to $10.3 million, or 0.18 percent of average loans in 2017. Significantly impacting net loan charge-offs during 2018 was a $5.2 million loan charge-off in the second quarter of 2018 for a commercial customer arising from a participation loan agreement with a lead bank and other participating banks. The loss resulted from fraudulent activities believed to be perpetrated by one or more executives employed by the borrower and its related entities. S&T's total exposure consisted of the participation loan of $4.9 million and a direct exposure of $950 thousand which was secured by vehicles and equipment liens. Subsequent to the loan charge-off in the second quarter, we received $0.4 million of recovery on this relationship.
Total nonperforming loans increased $22.2 million to $46.1 million, or 0.77 percent of total loans at December 31, 2018, compared to $23.9 million, or 0.42 percent of total loans at December 31, 2017.
The ALL at December 31, 2018, was $61.0 million, or 1.03 percent of total portfolio loans, compared to $56.4 million, or 0.98 percent of total portfolio loans at December 31, 2017. The increase in the level of the reserve is due to portfolio loan growth of $185.2 million and the increase in substandard loans during 2018. Refer to the Allowance for Loan Losses section of this MD&A for further details.

Noninterest income decreased $6.3 million, or 11.3 percent, in 2018 compared to 2017. The decrease was primarily related to gains on the sales of securities of $3.0 million in 2017, a $1.0 million gain from the sale of a branch in the fourth quarter of 2017 in other income and the sale of a majority interest in S&T Evergreen Insurance, LLC in the first quarter of 2018. As a result of this sale in 2018, insurance income decreased $4.9 million. A gain of $1.9 million was recognized related to this sale during 2018. The decrease in BOLI income related to a $0.7 million claim during the third quarter of 2017. Interest rate swap fees from our commercial customers increased $0.7 million compared to the prior year due to an increase in customer demand for this product. Debit and credit card fees increased $0.6 million compared to the prior year due to increased debit card usage. Service charges on deposit accounts also increased $0.6 million due to increases in fees.

NM - percentage not meaningful

Noninterest expense decreased $2.5 million, or 1.7 percent, to $145.4 million in 2018 compared to 2017. Salaries and employee benefits decreased $4.7 million during 2018 primarily due to lower restricted stock, incentive and commission costs and fewer employees mainly due to the sale of a majority of our insurance business in the first quarter 2018 and the sale of a branch office in the fourth quarter of 2017. FDIC insurance decreased $1.3 million due to improvements in the components used to determine the assessment. The increase of $1.8 million in data processing expense compared to 2017 was mainly due to the annual increase with our third-party data processor and recent outsourcing arrangement for certain components of our IT function. Other taxes increased $1.7 million due to a state sales tax assessment.
Our efficiency ratio (non-GAAP), which measures noninterest expense as a percent of noninterest income plus net interest income, on a FTE basis, excluding security gains/losses, was 50.60 percent for 2018 and 51.77 percent for 2017. Refer to Explanation of Use of Non-GAAP Financial Measures in Part II, Item 6 Selected Financial Data in this Report for a discussion of this non-GAAP financial measure.
Federal Income Taxes
Our federal income tax provision decreased $28.6 million to $17.8 million in 2018 compared to $46.4 million in 2017. The decrease in our 2018 income tax provision was primarily due to the corporate income tax rate reduction from 35 percent to 21 percent. Our 2017 income tax provision was calculated at the 35 percent corporate income tax rate and further increased by $13.4 million due to the re-measurement of our deferred tax assets and liabilities at the new corporate income tax rate of 21 percent enacted as part of the Tax Act on December 22, 2017.
The effective tax rate, which is total tax expense as a percentage of pretax income, decreased to 14.5 percent in 2018 compared to 38.9 percent in 2017. Historically, we have generated an annual effective tax rate that is less than the statutory rates of 21 percent for 2018 and 35 percent for 2017 due to benefits resulting from tax-exempt interest, excludable dividend income, tax-exempt income on BOLI and tax benefits associated with Low Income Housing Tax Credits, or LIHTC. However, due to the 2017 enactment of the Tax Act, our net DTA re-measurement of $13.4 million increased our effective tax rate by 11.3 percent in 2017.

Results of Operations
Year Ended December 31, 2017
Earnings Summary
On December 22, 2017, the Tax Act was signed into law. At the date of enactment, we were required to re-measure our deferred tax assets and liabilities, or net DTA, at the new lower corporate tax rate of 21 percent. We made a tax adjustment to re-measure our deferred tax assets and liabilities for the impact of the Tax Act that decreased 2017 net income by $13.4 million, or $0.38 per diluted share. The tax adjustment was recognized as an increase to our income tax expense in the fourth quarter of 2017. The new corporate tax rate of 21 percent is effective for tax years beginning January 1, 2018.
Net income increased $1.6 million, or 2.2 percent, to $73.0 million, or $2.09 per diluted share, in 2017 compared to $71.4 million or $2.05 per diluted share in 2016. The increase in net income was primarily due to an increase in net interest income of $22.5 million, or 11.1 percent, a decrease in the provision for loan losses of $4.1 million, or 22.7 percent, and an increase in security gains of $3.0 million. This was offset by increases of $4.7 million in noninterest expense and $21.1 million in the provision for income taxes.
Net interest income increased $22.5 million, or 11.1 percent, to $226 million compared to $203 million in 2016. The increases in short-term interest rates in 2017 positively impacted both net interest income and net interest margin during 2017. The increase in net interest income was primarily due to an increase in average interest-earning assets of $483 million, or 8.0 percent, offset by an increase in average interest-bearing liabilities of $356 million, or 8.0 percent, compared to 2016. The increase in average interest-earning assets primarily related to organic growth with average loans increasing $438 million, or 8.2 percent, during 2017. Most of this growth was in our commercial loan portfolio. The increases in average interest-bearing liabilities were mainly due to deposit growth and an increase in short-term borrowings. Average deposits increased $162 million, or 4.2 percent, and average borrowings increased $194 million, or 34.5 percent, for 2017. Net interest margin, on a fully taxable-equivalent, or FTE, basis (non-GAAP), increased nine basis points to 3.56 percent in 2017 compared to 3.47 percent for 2016.
The provision for loan losses decreased $4.1 million, or 22.7 percent, to $13.9 million during 2017 compared to $18.0 million in 2016. The lower provision for loan losses was due to decreases in net loan charge-offs and nonperforming loans and a decline in impaired loan balances and the related specific reserves. Net loan charge-offs decreased $3.0 million to $10.3 million, or 0.18 percent of average loans, for 2017 compared to $13.3 million, or 0.25 percent of average loans, in 2016. Impaired loans decreased $15.1 million, or 36 percent, with a decline in specific reserves of $0.7 million compared to 2016.
Total noninterest income increased $0.9 million to $55.5 million compared to $54.6 million in 2016. The increase in noninterest income was primarily due security gains of $3.0 million, a bank owned life insurance, or BOLI, claim of $0.7 million and a $1.0 million gain on a branch sale during 2017, compared to a gain of $2.1 million on the sale of our credit card portfolio and a $1.0 million pension curtailment gain in 2016.
Total noninterest expense increased $4.7 million to $148 million for 2017 compared to $143 million for 2016. The increase was mainly due to an increase in salaries and employee benefits of $3.5 million primarily due to annual merit increases, higher incentive costs and higher medical costs offset by lower pension expense.
The provision for income taxes increased $21.1 million to $46.4 million compared to $25.3 million in 2016. The increase was primarily due to the non-cash tax adjustment of $13.4 million for the re-measurement of our deferred tax assets and liabilities as a result of the corporate rate reduction, which was recorded as an increase to income tax expense and higher pre-tax income in 2017 compared to 2016.
Net Interest Income
Our principal source of revenue is net interest income. Net interest income represents the difference between the interest and fees earned on interest-earning assets and the interest paid on interest-bearing liabilities. Net interest income is affected by changes in the average balance of interest-earning assets and interest-bearing liabilities and changes in interest rates and spreads. The level and mix of interest-earning assets and interest-bearing liabilities is managed by our Asset and Liability Committee, or ALCO, in order to mitigate interest rate and liquidity risks of the balance sheet. A variety of ALCO strategies were implemented, within prescribed ALCO risk parameters, to produce what we believe is an acceptable level of net interest income.
The interest income on interest-earning assets and the net interest margin are presented on a FTE basis. The FTE basis adjusts for the tax benefit of income on certain tax-exempt loans and securities using the federal statutory tax rate of 35 percent for each period and the dividend-received deduction for equity securities. We believe this to be the preferred industry measurement of net interest income that provides a relevant comparison between taxable and non-taxable amounts.

(1)Nonaccruing loans are included in the daily average loan amounts outstanding.
(2)Tax-exempt income is on a FTE basis using the statutory federal corporate income tax rate of 35 percent for 2015, 2014 and 2013.
(3)Taxable investment income is adjusted for the dividend-received deduction for equity securities.
(4)Changes to rate/volume are allocated to both rate and volume on a proportionate dollar basis.
Net interest income on a FTE basis increased $40.2 million, or 26.2 percent, to $193.7 million compared to $153.5 million in 2014. Net interest margin on a FTE basis increased six basis points to 3.56 percent for 2015 compared to 3.50 percent compared to 2014. Net interest income was favorably impacted by accretion resulting from purchase accounting fair value adjustments related to the Merger of $6.2 million for 2015. This impacted net interest margin on a FTE basis by 12 basis points for 2015.
Interest income on a FTE basis increased $43.7 million, or 26.3 percent, compared to 2014. Average interest-earning assets increased $1.0 billion, or 23.8 percent, compared to 2014, mainly attributable to higher loan balances related to the Merger and organic growth. The rate earned on loans increased three basis points to 4.09 percent compared to 4.06 percent to the prior year. The rate was favorably impacted by purchase accounting accretion related to the Merger of $4.9 million, or 11 basis points, which was offset by the continued pressure on loan rates in the current environment. Average interest-bearing deposits with banks, which is primarily cash at the Board of Governors of the Federal Reserve, or Federal Reserve, decreased $27.5 million while average investment securities increased $83.4 million compared to 2014. Federal Home Loan Bank, or FHLB, and other restricted stock, increased $5.6 million compared to 2014 with a significant increase in the rate, primarily due to a special dividend received of $0.3 million during 2015. The FTE rate on total interest-earning assets increased eight basis points to 3.86 percent compared to 3.78 percent for 2014. The $4.9 million loan purchase accounting accretion had a positive impact on the interest-earning asset rate of ten basis points.
Interest expense increased $3.5 million to $16.0 million for 2015 as compared to $12.5 million for 2014. The increase in interest expense was mainly driven by an increase in average deposits of $714.6 million, primarily related to the Merger. Average interest-bearing customer deposits, which excludes brokered deposits, increased $564.7 million. Average brokered deposits increased $149.9 million and average borrowings increased $172.9 million compared to 2014 to fund strong loan growth during 2015. At December 31, 2015, average long-term borrowings increased $63.1million compared to December 31, 2014, as a result of shifting $100.0 million of short-term borrowings to a long-term variable rate borrowing in the second quarter of 2015. Overall, the cost of interest-bearing liabilities decreased one basis point to 0.40 percent compared to 0.41 percent for 2014. Deposit purchase accounting adjustments related to the Merger of $1.3 million positively impacted the cost of interest-bearing liabilities by three basis points.

Provision for Loan Losses
The provision for loan losses is the amount to be added to the ALL after adjusting for charge-offs and recoveries to bring the ALL to a level considered appropriate to absorb probable losses inherent in the loan portfolio. The provision for loan losses increased $8.7 million to $10.4 million for 2015 compared to $1.7 million for 2014. This increase in the provision is primarily related to an increase in loan charge-offs compared to the prior year.
Net charge-offs were $10.2 million, or 0.22 percent of average loans in 2015, compared to $0.1 million, or 0.00 percent of average loans in 2014. Net loan charge-offs of $0.1 million in 2014 were unusually low. Approximately $6.0 million of net charge-offs during 2015 related to loans acquired in the Merger, primarily due to four relationships that experienced credit deterioration subsequent to the acquisition date. Total nonperforming loans increased to $35.4 million, or 0.70 percent of total loans at December 31, 2015, compared to $12.5 million, or 0.32 percent of total loans at December 31, 2014. The increase in nonperforming loans primarily related to acquired loans from the Merger that experienced credit deterioration subsequent to the acquisition date. Special mention and substandard commercial loans increased $71.3 million to $183.5 million from $112.2 million at December 31, 2014, primarily related to the Merger. The ALL at December 31, 2015, was $48.1 million, or 0.96 percent of total portfolio loans, compared to $47.9 million, or 1.24 percent of total portfolio loans at December 31, 2014. The decrease in the overall level of the reserve as a percentage to total portfolio loans is partly due to the Merger as the acquired loans were recorded at fair value with no carry over of the ALL. The ALL as a percentage of originated loans was 1.10 percent at December 31, 2015. Refer to the Allowance for Loan Losses section of this Management’s Discussion and Analysis of Financial Condition and Results of Operations, or MD&A, for further details.

Noninterest income increased $4.7 million, or 10.1 percent, in 2015 compared to 2014, with increases in almost all noninterest income categories. Various categories of noninterest income were positively impacted by the Merger which closed on March 4, 2015.
Mortgage banking income increased $1.6 million in 2015 compared to 2014 due to an increase in the volume of loans originated for sale in the secondary market, in part due to the Merger, and more favorable pricing on loan sales. Debit and credit card fees increased $1.3 million due to the Merger and reversal of a $0.5 million customer rewards program liability related to the planned strategic repositioning of the credit card portfolio. Service charges on deposit accounts increased $1.1 million due to the Merger and due to fee increases in the second half of 2014. The increases in BOLI income and letter of credit origination fees were primarily related to the Merger.
Insurance fees decreased $0.5 million primarily due to increased competition and a decline in customers in the energy sector due to industry consolidation.

Noninterest expense increased $19.5 million, or 16.6 percent, to $136.7 million, for the year ended December 31, 2015 compared to 2014. The increase was due in part to higher operating expenses related to the Merger which closed on March 4, 2015 and $3.2 million of merger related expenses.
In 2015, we incurred merger related expenses of $3.2 million compared to $0.7 million in 2014. These expenses included $1.3 million for data processing contract termination and conversion costs, $1.2 million in legal and professional expenses, $0.4 million in severance payments and $0.3 million in various other expenses.
Salaries and employee benefits increased $7.8 million during 2015 primarily due to additional employees, annual merit increases and higher pension and incentive expense. Approximately $4.1 million of the increase related to the addition of new employees resulting from the Merger. Annual merit increases resulted in $1.6 million of additional salary expense. Pension expense increased $1.0 million due to a change in actuarial assumptions used to calculate our pension liability. Incentive expense increased $1.3 million due to a higher number of participants and strong performance in 2015.
Operating expenses increased in 2015 compared to 2014 due to the Merger. The increase of $2.4 million in net occupancy expense and $0.8 million in furniture and equipment expense compared to 2014 was due to additional locations acquired as part of the Merger, as well as additional expenses related to our newer locations, including our LPO in central Ohio, our branches in Indiana and McCandless and our training and operations center. Other noninterest expense increased $1.2 million primarily due to training and travel related to the Merger and our expansion efforts. FDIC insurance increased $1.0 million, other taxes increased $0.7 million and amortization of intangibles increased $0.7 million all related to the Merger. The increase of $0.9 million in data processing expense in 2015 primarily related to an increased customer processing base due to the Merger and growth in digital channels. The increase in marketing expense of $0.9 million is due to additional marketing promotions.
Our efficiency ratio, which measures noninterest expense as a percent of noninterest income plus net interest income, on a FTE basis, excluding security gains/losses, was 56 percent for 2015 and 59 percent for 2014. Refer to page 48 Explanation of Use of Non-GAAP Financial Measures for a discussion of this non-GAAP financial measure.

Federal Income Taxes
We recorded a federal income tax provision of $24.4 million in 2015 compared to $17.5 million in 2014. The effective tax rate, which is the provision for income taxes as a percentage of pretax income was 26.7 percent in 2015 compared to 23.2 percent in 2014. We ordinarily generate an annual effective tax rate that is less than the statutory rate of 35 percent due to benefits resulting from tax-exempt interest, excludable dividend income, tax-exempt income on bank owned life insurance, or BOLI, and tax benefits associated with Low Income Housing Tax Credits, or LIHTC. The increase to our effective tax rate was primarily due to an increase of $16.1 million in pre-tax income.

Results of Operations
Year Ended December 31, 2014
Earnings Summary
Net income available to common shareholders increased $7.4 million, or 14.6 percent, to $57.9 million or $1.95 per share in 2014 compared to $50.5 million or $1.70 per share in 2013. The increase in net income was primarily due to an increase in net interest income of $8.8 million, or 6.4 percent and a $6.6 million, or 79 percent, decrease in the provision for loan losses.
Net interest income increased $8.8 million, or 6.4 percent, to $148.0 million compared to $139.2 million in 2013. The increase in net interest income is mainly due to interest earning asset growth and lower funding costs. Total average interest earning assets increased $275.5 million, or 6.7 percent, compared to 2013. The increase was driven by higher average loans, which is due to our successful efforts in growing our loan portfolio organically over the past year. Net interest margin, on a FTE basis, was unchanged at 3.50 percent for both 2014 and 2013.
The provision for loan losses decreased $6.6 million, or 79 percent, to $1.7 million during 2014 compared to $8.3 million in 2013. The lower provision for loan losses was due to improving economic conditions in our markets which have positively impacted our asset quality metrics in all categories, including decreases in loan charge-offs, nonaccrual loans, special mention and substandard loans and the delinquency status of our loan portfolio. Net loan charge-offs were only $0.1 million for 2014 compared to $8.5 million in 2013.
Total noninterest income decreased $5.2 million, or 10.1 percent, to $46.3 million for 2014 compared to $51.5 million for 2013. The decrease in noninterest income was primarily related to a $3.1 million gain on the sale of our merchant card servicing business that occurred in 2013. Mortgage banking income decreased $1.2 million, or 57 percent, due to higher interest rates in 2014 compared to 2013, resulting in a decrease in the volume of loans being originated and sold. Interest rate swap fees with our commercial customers decreased $0.6 million, or 57 percent, due to a decline in customer demand for this product. These decreases were partially offset by an increase in our wealth management fees of $0.6 million, or six percent, due to new business development efforts and certain fee increases.
Total noninterest expense decreased $0.2 million to $117.2 million for 2014 compared to $117.4 million for 2013. Despite significant growth in 2014, expenses were well controlled. Notable declines were a decrease of $2.1 million for pension expense resulting from a change in actuarial assumptions used to calculate our pension liability and a $0.8 million decrease in other taxes due to legislative changes that resulted in a reduction in Pennsylvania shares tax. These decreases were offset by relatively small increases in various expense items in numerous categories.
The provision for income taxes increased $3.0 million to $17.5 million compared to $14.5 million in 2013. The increase is primarily due to a $10.4 million increase in pretax income.
Net Interest Income
Our principal source of revenue is net interest income. Net interest income represents the difference between the interest and fees earned on interest-earning assets and the interest paid on interest-bearing liabilities. Net interest income is affected by changes in the average balance of interest-earning assets and interest-bearing liabilities and changes in interest rates and spreads.Maintaining consistent spreads between interest-earning assets and interest-bearing liabilities is significant to our financial performance because net interest income comprised 76 percent of operating revenue in 2014 and 74 percent of operating revenue in 2013. Refer to page 48 Explanation of Use of Non-GAAP Financial Measures for a discussion of operating revenue as a non-GAAP financial measure. The level and mix of interest-earning assets and interest-bearing liabilities is managed by our ALCO in order to mitigate interest rate and liquidity risks of the balance sheet. A variety of ALCO strategies were implemented, within prescribed ALCO risk parameters, to maintain an acceptable net interest margin on interest-earning assets.
The interest income on interest-earning assets and the net interest margin are presented on a FTE basis. The FTE basis adjusts for the tax benefit of income on certain tax-exempt loans and securities using the federal statutory tax rate of 35 percent for each period and the dividend-received deduction for equity securities. We believe this measure to be the preferred industry measurement of net interest income that provides a relevant comparison between taxable and non-taxable amounts.

The decrease in the cost of interest-bearing deposits was mainly due to the maturity of higher rate CDs being replaced by lower rate deposits. In addition to a shift in the mix of our interest-bearing liabilities, interest expense for 2014 also decreased due to the redemption of $45.0 million of subordinated debt during the second quarter of 2013. Interest expense on average borrowings declined by $0.8 million in 2014 compared to 2013.

Provision for Loan Losses
The provision for loan losses is the amount to be added to the ALL after adjusting fornet loan charge-offs and recoverieshave been deducted to bring the ALL to a level considered appropriatedetermined to be adequate to absorb probable losses inherent in the loan portfolio. The provision for loan losses decreased $6.6$4.1 million, or 7922.7 percent, to $1.7$13.9 million for 20142017 compared to $8.3$18.0 million for 2013. The2016. This decrease is due to continued improvement in the economic conditionsprovision for loan losses is primarily related to decreases in our markets which resulted in a significant improvement in our asset quality. net loan charge-offs and nonperforming loans and lower impaired loan balances and the related specific reserves.
Net charge-offs were only $0.1decreased $3.0 million, or zero23 percent, to $10.3 million, or 0.18 percent of average loans in 2014,2017, compared to $8.5$13.3 million, or 0.25 percent of average loans in 2013.2016.

Noninterest income decreased $5.2increased $0.8 million, or 10.11.5 percent, in 20142017 compared to 2013. The2016. Net gains on the sale of securities and a $1.0 million gain from the sale of a branch in 2017 were mostly offset by a $2.1 million decrease primarily related to the gain on the sale of our merchantcredit card servicing businessportfolio and a $1.0 million defined benefit plan curtailment gain in 2013 combined with decreases in mortgage banking2016. The curtailment gain was due to an amendment to freeze benefit accruals under the qualified and other noninterest income. These decreases were partially offset by an increasenonqualified defined benefit pension plans effective March 31, 2016.
The decrease in wealth management fees.
Duringfees of $0.7 million is primarily due to a decline in advisory fees related to the firstdissolution of the mutual fund, compared to the prior year. The increase in BOLI income related to a $0.7 million claim during the third quarter of 2013, we sold our merchant card servicing business for $4.8 million and paid deconversion and termination fees of $1.7 million to the merchant processor resulting in a net gain of $3.1 million. In conjunction with the sale of the merchant card servicing business, we entered into a marketing and sales alliance agreement with the purchaser, providing transition fees, royalties and referral revenue. Income from the marketing and sales alliance agreement is included in debit and credit card fees.
Mortgage banking income decreased $1.2 million in 2014 compared to 2013 due to an increase in mortgage rates that occurred in the second quarter of 2013, resulting in a decrease in the volume of loans originated for sale in the secondary market, less favorable pricing on loan sales and also impacted the valuation of our mortgage servicing rights, or MSRs, asset. During the year ended December 31, 2014, we sold 33 percent fewer mortgages with $42.0 million in loan sales compared to $62.9 million during 2013. We maintain the servicing rights when selling our loans and experienced a minor impairment on our MSR asset in 2014 compared to an impairment recapture of $0.8 million in 2013.
2017. Interest rate swap fees from our commercial customers decreased $0.6$0.5 million compared to the prior year due to a declinedecrease in customer demand for this product. The decrease in other noninterest income of $0.5 million for year ended December 31, 2014 was primarily attributable to a change in the valuation of our rabbi trust related to a deferred compensation plan, which has a corresponding offset in salaries and benefit expense resulting in no impact to net income. Wealth management fees increased $0.6 million due to higher assets under management, new business development efforts and fee increases.

We do not intend to sell and it is more likely than not that we will not be required to sell any of the securities in an unrealized loss position before recovery of their amortized cost. We did not record any OTTI in 2015, 2014 and 2013.2018, 2017 or 2016.

The loan portfolio represents the most significant source of interest income for us. The risk that borrowers will be unable to pay such obligations is inherent in the loan portfolio. Other conditions such as downturns in the borrower’s industry or the overall economic climate can significantly impact the borrower’s ability to pay.

We maintain a General Lending Policy to control the quality of our loan portfolio. The policy delegates the authority to extend loans under specific guidelines and underwriting standards. The General Lending Policy is formulated by management and reviewed and ratified annually by the Board of Directors.
Total portfolio loans increased $1.2 billion,$185.2 million, or 30.03.2 percent, since December 31, 2014, to $5.0$5.9 billion at December 31, 2015. The increase was primarily due2018 compared to the addition of $788.7$5.8 billion at December 31, 2017. CRE increased $235.8 million, of loans from the Mergeror 8.8 percent, and $370.2C&I increased $60.2 million, of organic growth. The $788.7 million of loans acquiredor 4.2 percent, offset by a decrease in the Merger consisted of $331.6 million of CRE, $184.2 million of C&I, $92.4 million of commercial construction $116.9loans of $127.1 million compared 2017. The commercial portfolio was impacted by higher loan payoffs through the third quarter of residential mortgage, $25.6 million2018 and an increasingly competitive market throughout the year. New construction loan activity was outpaced by loan payoffs and transfers to CRE upon completion of home equity, $36.1 million of installment and other consumer and $1.9 million of consumer construction. Organic loan growth was strong across all of our commercial portfolios and in our residential mortgage portfolio with total organic growth of $370.2 million during 2015. Almost 60 percent of our total organic loan growth, or $219.6 million, was from our newer markets in Ohio and New York. Further driving loan growth was the expansion of our sales team with the addition of commercial lenders in various markets.construction period.
Commercial loans, including CRE, C&I and commercial construction,Commercial Construction, comprised 76 percent and 7579 percent of total portfolio loans at December 31, 20152018 and 2014.78 percent at December 31, 2017. Although commercial loans can have a relatively higher risk profile, management believes these risks are mitigated through active portfolio management, conservative underwriting standards and continuous portfolio review. The loan-to-value, or LTV, policy guidelines for CRE loans are generally 65-80 percent. At December 31, 2015,2018, variable rate commercial loans were 77represented 74 percent of the total commercial loans compared to 7975 percent in 2014.
Total commercial loans have increased $944.4 million, or 32.6 percent, from December 31, 2014 with growth in all portfolios. CRE loans increased $484.4 million, or 28.8 percent, with $331.6 million of the growth from the Merger and $152.8 of organic growth. C&I loans increased $262.7 million, or 26.4 percent, with $184.2 million of growth from the Merger and $78.5 million of organic growth. Commercial construction loans increased $197.3 million, or 91.3 percent, with $92.4 million related to the Merger and $104.9 million of organic growth.2017.
Consumer loans represent 2421 percent of our loan portfolio at December 31, 20152018 compared to 2522 percent at
December 31, 2014. Total consumer2017. Consumer loans have increased $214.5$16.3 million or 22.0 percent, from December 31, 2014 with $180.5 million of the increase due to the Merger and $34.0 million of organic growth.
Thegrowth primarily in our residential mortgage portfolio increased $149.8 million, or 30.1 percent, with $116.9 million of growth from the Merger and $32.9 million of organic growth. $27.9 million.
Residential mortgage lending continues to be a focus through a centralized mortgage origination department, secondary market activities and the utilization of commission compensated originators. Management believes that continued adherence to our conservative mortgage lending policies for portfolio mortgage loans will be as important in a growing economy as it was during the downturn in recent years. The LTV policy guideline is 80 percent for residential first lien mortgages. Higher LTV loans may be approved with the appropriate private mortgage insurance coverage. We primarily limit our fixed rate portfolio mortgage loans to a maximum term of 20 years for traditional mortgages, 30 year fixed rate construction loans and 15 yearsadjustable rate mortgages with a maximum amortization term of 30 years for balloon payment mortgages.years. We may originate home equity loans with a lien position that is second to unrelated third party lenders, but normally only to the extent that the combined LTV considering both the first and second liens does not exceed 100 percent of the fair value of the property. Combo mortgage loans consisting of a residential first mortgage and a home equity second mortgage are also available.
We originate and sell loans into the secondary market, primarily to Fannie Mae. We sell these loans in order to mitigate interest-rate risk associated with holding lower rate, long-term residential mortgages in the loan portfolio and to generate fee revenue from sales and servicing of the loans. During 2018 and to maintain the primary customer relationship. During 2015 and 2014,2017, we sold $77.2$79.3 million and $40.1$78.8 million of 1-4 family mortgages to Fannie Mae. In addition, at December 31, 2018, we service $361.2were servicing $473.2 million of secondary market mortgage loans that we had originated at December 31, 2015and sold into the secondary market, compared to $327.2$441.0 million at December 31, 2014. Loans sold to Fannie Mae in 2015 increased compared to 2014 due to the Merger and increased organic volume.2017.

We also offer a variety of unsecured and secured consumer loan and credit card products. LTV guidelines for direct loans are generally 90-100 percent of invoice for new automobiles and 80-90 percent of National Automobile Dealer Association value for used automobiles.

Credit Quality
On a quarterly basis, a criticized asset meeting is held to monitor all special mention and substandard loans greater than $0.5$1.5 million. These loans typically represent the highest risk of loss to us. Action plans are established and these loans are monitored through regular contact with the borrower, review of current financial information and other documentation, review of all loan or potential loan restructures or modifications and the regular re-evaluation of assets held as collateral.
Additional credit risk management practices include periodic review and update toof our lending policies and procedures to support sound underwriting practices and portfolio management through portfolio stress testing. During 2018, we strengthened our portfolio monitoring process to include an annual review of all commercial loans greater than $1.5 million. Commercial loans less than $1.5 million are monitored through portfolio management software that identifies credit risk indicators. Our Loan Review process serves to independently monitor credit quality and assess the effectiveness of credit risk management practices to provide oversight of all corporate lending activities. The Loan Review function has the primary responsibility for assessing commercial credit administration and credit decision functions of consumer and mortgage underwriting, as well as providing input to the loan risk rating process.

(1)Subsequent to releasing our earnings for the fourth quarter of 2015 on January 26, 2016, we obtained new information regarding the collectability of a $4.7 million C&I loan. The loan is now classified as an impaired loan, with no required reserve, and as a nonperforming loan. We previously reported in our fourth quarter of 2015 earnings release nonperforming loans of $30.7 million, total NPA's of $31.0 million, nonperforming loans as a percentage of total gross loans of 0.61 percent, NPA's to total gross loans plus OREO of 0.61 percent and ALL to nonperforming loans of 157 percent. Even though the information regarding the collectability of this loan did not become available to us until after the release of our earnings for the fourth quarter of 2015, GAAP requires that this information be reflected in our audited Consolidated Financial Statements for 2015 and related disclosures. Thus, revised amounts and ratios are included within this Form 10-K.
Our policy is to place loans in all categories in nonaccrual status when collection of interest or principal is doubtful, or generally when interest or principal payments are 90 days or more past due. There were no loans 90 days or more past due and still accruing at December 31, 20152018 or December 31, 2014.2017.
NPAs increased $23.1$24.8 million to $35.7$49.2 million at December 31, 20152018 compared to $12.6$24.4 million at December 31, 2014. NPAs were at historically low levels in 2014.2017. New nonperforming loan formation was $28.4 million for 2018 compared to $1.2 million for 2017. The increase in NPAs during 2015 was primarily duenonperforming loans related mainly to credit deterioration on acquiredthe reclassification of loans sincein the acquisition datefourth quarter of 2018 including an $11.5 construction loan, a $7.7 million CRE loan and a $4.7$4.4 million C&I loan. Included in the total NPAs of $35.7OREO increased $2.6 million was approximately $16.2 million of loans from the Merger all of which became 90 days past due subsequentrelated to the merger date.two land lots that are no longer intended to be future branch locations.
TDRs are loans where we, for economic or legal reasons related to a borrower’s financial difficulties, grant a concession to the borrower that we would not otherwise grant. We strive to identify borrowers in financial difficulty early and work with them to modify the terms before their loan reaches nonaccrual status. These modified terms generally include extensions of maturity dates at a stated interest rate lower than the current market rate for a new loan with similar risk characteristics, reductions in contractual interest rates or principal deferment. While unusual, there may be instances of principal forgiveness. Generally these concessionsThese modifications are generally for a period of at least six months.longer term periods that would not be considered insignificant. Additionally, we classify loans where the debt obligation has been discharged through a
Chapter 7 Bankruptcybankruptcy and not reaffirmed by the borrower as TDRs.
TDRs
Item 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued


An accruing loan that is modified into a TDR can be returned to accruingremain in accrual status if, based on a current credit analysis, collection of principal and interest in accordance with the following criteria are met: 1) the ultimate collectability of all contractual amounts due, according to the restructured agreement,modified terms is not in doubtreasonably assured, and 2) there is a period of a minimum of six months of satisfactory payment performance by the borrower either immediatelyhas demonstrated sustained historical repayment performance for a reasonable period before or after the restructuring.modification. All TDRs are considered to be impaired loans and will be reported as impaired loans for their remaining lives, unless the restructuring agreement specifies an interest rate equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk and we fully expect that the remaining principal and interest will be collected according to the restructured agreement. AllFor all TDRs, regardless of size, as well as all other impaired loans, we conduct further analysis to determine the probable loss and assign a specific reserve to the loan if deemed appropriate. Further, all impaired loans are reported as nonaccrual loans unless the loan is a TDR that has met the requirements noted above to be returned to accruing status.

Table TDRs can be returned to accruing status if the ultimate collectability of Contentsall contractual amounts due, according to the restructured agreement, is not in doubt and there is a period of a minimum of six months of satisfactory payment performance by the borrower either immediately before or after the restructuring.

Item 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS -- continued


As an example, consider a substandard commercial construction loan that is currently 90 days past due where the loan is restructured to extend the maturity date for a period longer than would be considered an insignificant period of time. The post-modification interest rate given to the borrower is not increasedconsidered to correspond withbe lower than the current creditmarket rate for new debt with similar risk of the borrower and all other terms remain the same according to the original loan agreement. This loan will be considered a TDR as the borrower is experiencing financial difficulty and a concession has been granted.granted due to the long extension, resulting in payment delay as well as the rate being lower than the current market rate for new debt with similar risk. The loan will be reported as nonaccrual TDR and as an impaired loan and a TDR.loan. In addition, the loan could be charged down to the fair value of the collateral if a confirmed loss exists. If the loan subsequently performs, by means of making on-time principal and interest payments according to the newly restructured terms for a period of six months, and it is expected that all remaining principal and interest will be collected according to the terms of the restructured agreement, the loan will be returned to accrual status and reported as an accruing TDR. The loan will remain an impaired loan for the remaining life of the loan because the interest rate was not adjusted to be equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk.
As ofTDRs increased $1.8 million to $27.9 million at December 31, 2015, we had $31.62018 compared to $26.1 million in totalat December 31, 2017. The $27.9 million of TDRs including $24.0at December 31, 2018 included $16.8 million of TDRS that were performing and $7.6$11.1 million that were nonperforming. This is a decreasean increase from December 31, 20142017 when we had $42.4$26.1 million in TDRs, including $37.0$14.9 million that were performing and $5.4$11.2 million that were nonperforming. The $10.8 million decrease in total TDRsincrease is primarily due to new TDRs totaling $11.4 million, which were offset by principal reductions during 2015. and charge-offs.
Loan modifications resulting in TDRs increased in 2015 with 60 modifications or $8.3 million of new TDRs during 2018 included 46 modifications for $12.7 million compared to 4436 modifications or $4.9for $5.8 million of new TDRs in 2014.2017. Included in the 20152018 new TDRs were 3229 loans totaling $1.2 million related to Chapter 7 bankruptcy filings that were not reaffirmed, thus resulting in discharged debt, which compares to 2926 loans totaling $1.1$0.8 million in 2014. For the year ended December 31, 2015 we had eight TDRs for $0.4 million that met the above requirements for being returned to performing status compared to nine TDRs for $1.9 million during 2014.2017.

Closed-end installment loans, amortizing loans secured by real estate and any other loans with payments scheduled monthly are reported past due when the borrower is in arrears two or more monthly payments. Other multi-payment obligations with payments scheduled other than monthly are reported past due when one scheduled payment is due and unpaid for 30 days or more. We monitor delinquency on a monthly basis, including early stage delinquencies of 30 to 89 days past due for early identification of potential problem loans.
Loans past due 90 days or more increased $22.9$22.1 million compared to December 31, 20142017 and represented 0.700.77 percent of total loans at December 31, 2015.2018. The increase related mainly to new loans in the fourth quarter of 2018 including an $11.5 construction loan, a $7.7 million CRE loan and a $4.4 million C&I loan. Loans past due by 30 to 89 days increased $16.0$0.9 million and represent 0.49represented 0.22 percent of total loans at December 31, 2015. The increase in our delinquency categories is mainly due to the Merger which accounted for

approximately $16.2 million of the total increase in loans past due 90 days or more and $14.2 million of the total increase in loans past due by 30 to 89 days. Delinquency increased in all loan categories in 2015, with the exception of installment and other consumer.2018.
Allowance for Loan Losses
We maintain an ALL at a level determined to be adequate to absorb estimated probable credit losses inherent within the loan portfolio as of the balance sheet date.date, and it is presented as a reserve against loans in the Consolidated Balance Sheets. Determination of an adequate ALL is inherently subjective and may be subject to significant changes from period to period. The methodology for determining the ALL has two main components: evaluation and impairment tests of individual loans and evaluation and impairment tests of certain groups of homogeneous loans with similar risk characteristics.
Our charge-off policy for commercial loans requires that loans and other obligations that are not collectible be promptly charged-off when the loss becomes probable, regardless of the delinquency status of the loan. We may elect to recognize a partial charge-off when management has determined that the value of collateral is less than the remaining investment in the loan. A loan or obligation does not need to be charged-off, regardless of delinquency status, if (i) management has determined there exists sufficient collateral to protect the remaining loan balance and (ii) there exists a strategy to liquidate the collateral. Management may also consider a number of other factors to determine when a charge-off is appropriate. These factors may include, but are not limited to:
The status of a bankruptcy proceedingproceeding;
The value of collateral and probability of successful liquidation; and/or
The status of adverse proceedings or litigation that may result in collectioncollection.

Consumer unsecured loans and secured loans are evaluated for charge-off after the loan becomes 90 days past due. Unsecured loans are fully charged-off and secured loans are charged-off to the estimated fair value of the collateral less the cost to sell.

Net loan charge-offs in 2018 were at historic low levelssignificantly impacted by a $5.2 million loan charge-off in 2014.the second quarter of 2018 for a commercial C&I customer arising from a participation loan agreement with a lead bank and other participating banks. The Merger accountedloss resulted from fraudulent activities believed to be perpetrated by one or more executives employed by the borrower and its related entities. During the fourth quarter of 2018, we had an increase in nonperforming loans with an $11.5 construction loan, a $7.7 million CRE loan and a $4.4 million C&I loan. The construction nonperforming loan resulted in a $2.4 million loan charge-off and the CRE loan had a $1.3 million specific reserve for approximately $6.0the fourth quarter ended December 31, 2018. Net loan charge-offs for 2017 of $10.3 million included $8.4 million of acquired loan charge-offs during 2015, which primarily related to four relationships that experienced credit deterioration subsequent to the acquisition date. Net charge-offs increased significantly inand $2.1 million for two originated C&I related to two originated loans, and in commercial construction due to the aforementioned acquired loans in comparison to 2014.

An inherent risk to the loan portfolio as a whole is the condition of the economy in our markets. In addition, each loan segment carries with it risks specific to the segment. We develop and document a systematic ALL methodology based on the following portfolio segments: 1) CRE, 2) C&I, 3) Commercial Construction, 4) Consumer Real Estate and 5) Other Consumer.
CRE loans are secured by commercial purpose real estate, including both owner occupiedowner-occupied properties and investment properties for various purposes such as hotels, strip malls and apartments. Operations of the individual projects as well as global cash flows of the debtors are the primary sources of repayment for these loans. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the collateral type as well as the business prospects of the lessee, if the project is not owner occupied.owner-occupied.

Item 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued


C&I loans are made to operating companies or manufacturers for the purpose of production, operating capacity, accounts receivable, inventory or equipment financing. Cash flow from the operations of the company is the primary source of repayment for these loans. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the industry of the company. Collateral for these types of loans often dodoes not have sufficient value in a distressed or liquidation scenario to satisfy the outstanding debt.
Commercial construction loans are made to finance construction of buildings or other structures, as well as to finance the acquisition and development of raw land for various purposes. While the risk of these loans is generally confined to the construction period, if there are problems, the project may not be completed, and as such, may not provide sufficient cash flow on its own to service the debt or have sufficient value in a liquidation to cover the outstanding principal. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the type of project and the experience and resources of the developer.
Consumer real estate loans are secured by first and second lienliens such as home equity loans, home equity lines of credit and 1-4 family residences,residential mortgages, including purchase money mortgages. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk of this segment. The state of the local housing markets can also have a significant impact on this segment because low demand and/or declining home values can limit the ability of borrowers to sell a property and satisfy the debt.
Other consumer loans are made to individuals and may be secured by assets other than 1-4 family residences, as well as unsecured loans. This segment includes auto loans, unsecured loans and lines and credit cards. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The value of the collateral, if there is any, is less likely to be a source of repayment due to less certain collateral values.
The following is the ALL balance by portfolio segment as of December 31:

Significant to our ALL is a higher concentration of commercial loans. The ability of borrowers to repay commercial loans is dependent upon the success of their business and general economic conditions. Due to the greater potential for loss within our commercial portfolio, we monitor the commercial loan portfolio through an internal risk rating system. Loan risk ratings are assigned based upon the creditworthiness of the borrower and are reviewed on an ongoing basis according to our internal policies. Loans rated special mention or substandard have potential or well-defined weaknesses not generally found in high quality, performing loans, and require attention from management to limit loss.

The ALL was $48.1$61.0 million, or 0.96 percent of total loans, at December 31, 2015 as compared to $47.9 million, or 1.241.03 percent of total portfolio loans, at December 31, 2014. The ALL as a percentage2018, compared to $56.4 million, or 0.98 percent of originatedtotal portfolio loans, was 1.10 percent at December 31, 2015.2017. The decreaseincrease in the ALL to total portfolio loans from December 31, 2015 to December 31, 2014 is partly due to the Merger. Acquired loans of $788.7$4.6 million were recorded at fair value with no carryover of the ALL. Additional credit deterioration on acquired loans, in excess of the original credit discount embedded in the fair value determination at the date of acquisition, was recognized in the ALL through the provision for loan losses.
Overall, the total ALL balance remains relatively consistent, but a higher percentage of the ALL is attributable to the commercial construction portfolio segment due to increased inherent risk in this loan portfolio. The commercial construction portfolio loan balances have increased and we have experienced an increase in the delinquency rate during 2015 in this portfolio. Impaired loans increased $4.4 million, or 10.8 percent, from December 31, 2014. As of December 31, 2015, we had $45.7 million of impaired loans which included $19.0 million of new impaired loans during 2015. The $19.0 million of new impaired loans were due to $9.9 million of acquired loans, primarily due to nine relationships that experienced credit deterioration sincea $2.9 million increase in the acquisition date, and $9.1 million of originated loans. The reserve for loans collectively evaluated for impairment did not change significantlyand an increase of $1.7 million in specific reserves for loans individually evaluated for impairment at December 31, 20152018 compared to December 31, 2014. While we experienced an2017. The increase our asset quality metrics, the changes have primarily been relatedin loans collectively evaluated for impairment was due to the acquired loan portfolio which was accounted for at fair value at the date of acquisition. Further deterioration in acquireddowngrades during 2018. Commercial special mention and substandard loans was accounted for through additional provision during 2015 and considered in the total ALLincreased $67.7 million to $268.5 million compared to $200.8 million at December 31, 2015.2017, with an increase of $110.5 million in substandard offset by a decrease of $42.8 million in special mention. The increase in substandard loans from December 31, 2017 was mainly due to the receipt of updated financial information from our borrowers that resulted in the loans being downgraded. The increase in specific reserves related to a $1.3 million reserve established for a CRE loan. Impaired loans increased $22.7 million from December 31, 2017 due to three large commercial nonperforming, impaired loans totaling $23.6 million. As of December 31, 2018, we had $49.5 million of impaired loans compared to $26.8 million at December 31, 2017.
Federal Home Loan Bank and Other Restricted Stock
At December 31, 20152018 and 2014,2017, we held FHLB of Pittsburgh stock of $22.2$28.6 million and $14.3$28.4 million. This investment is carried at cost and evaluated for impairment based on the ultimate recoverability of the par value. We hold FHLB stock because we are a member of the FHLB of Pittsburgh. The FHLB requires members to purchase and hold a specified level of FHLB stock based upon on the members’ asset values, level of borrowings and participation in other programs offered. Stock in the FHLB is non-marketable and is redeemable at the discretion of the FHLB. Members do not purchase stock in the FHLB for the same reasons that traditional equity investors acquire stock in an investor-owned enterprise. Rather, members purchase stock to obtain access to the products and services offered by the FHLB. Unlike equity securities of traditional for-profit enterprises, the stock of the FHLB does not provide its holders with an opportunity for capital appreciation because, by regulation, FHLB stock can only be purchased, redeemed and transferred at par value. We reviewed and evaluated the FHLB capital stock for OTTI at December 31, 2015.2018. The FHLB reported improved earnings throughout 20152018 and 20142017 and continues to exceed all capital ratios required. Additionally, we considered that the FHLB has been paying dividends and actively redeeming excess stock throughout 20152018 and 2014.2017. Accordingly, we believe sufficient evidence exists to conclude that no OTTI exists at December 31, 2015.2018.
At December 31, 2015 and 2014, we held Atlantic Community Bankers’ Bank, or ACBB, stock of $0.9 million and $0.8 million. This investment is carried at cost and evaluated for impairment based on the ultimate recoverability of the investment. Like FHLB stock, members purchasecarrying value. We do not currently use their membership products and services. We acquired ACBB stock to access the products and services offered, as opposed to traditional equity investors who acquire stock for purposes such as appreciation in value. S&T acquired thethrough various mergers of banks that were ACBB members. ACBB stock asis evaluated for OTTI on a resultquarterly basis.

Deposits
The following table presents the composition of bank acquisitions and does not use the bank’s member services. ACBB continues to be classified as well capitalized by regulatory guidelines and the current purchase price for new members is $3,500 per share. As of December 31, 2015, the book value of our ACBB stock was $2,047 per share; therefore, management believes that no OTTI existsdeposits at December 31, 2015.31:

Deposits are our primary source of funds. We believe that our deposit base is stable and that we have the ability to attract new deposits. Total deposits at December 31, 20152018 increased $967.8$246.0 million, or 24.84.5 percent, primarily due to $722.3 million of deposits added from the Merger. Of the $722.3 million added from the Merger, $228.2 million was noninterest-bearing demand, $151.6 million was interest-bearing demand, $87.3 million was money market, $24.8 million was savings and $230.4 million was CDs including brokered deposits. Overall, ourDecember 31, 2017. Total customer deposits increased $771.2$165.4 million from December 31, 2014. Customer deposit growth included a $143.82017. Noninterest-bearing demand deposits increased $33.4 million or 13.3 percent, increase in noninterest-bearing demand, a $253.9 million, or 76.2 percent, increase in interest-bearing demand, a $75.5 million, or 24.4 percent,and money market increased $297.9 million. The increase in money market deposits is related to a $34.2competitively-priced, indexed product. These increases were offset by declines in interest-bearing demand deposits of $32.5 million, or 3.3 percent, increase in savings deposits of $108.1 million, and $263.8 million, or 28.3 percent increase in CDs.
Ourcertificates of deposits of $25.3 million. These decreases were a mainly a result of migration into the indexed money market product. Total brokered deposits increased $196.5$80.6 million or 88.4 percent, compared tofrom December 31, 2014.2017. Brokered deposits consist of CDs, money market, and interest-bearing demand funds and are an additional source of funds utilized by the ALCO as a way to diversify funding sources, as well as manage our funding costs and structure. The increase in brokered deposits was primarily due to funding needs to support our asset growth.
The daily average balance of deposits and rates paid on deposits are summarized in the following table for the years ended December 31 in the following table:31:

Borrowings are an additional source of funding for us. We defineSecurities sold under repurchase agreements are repurchase agreements with our local retail customers as retail REPOs.customers. Securities pledged as collateral under these REPO financing arrangements cannot be sold or repledged by the secured party and are therefore accounted for as a secured borrowing. Short-term borrowings are forcomprised of FHLB advances with terms underof one year and were comprised primarily of FHLB advances.under. Long-term borrowings are for terms greater than one year and consist primarily of FHLB advances. FHLB borrowingsadvances are for various terms and are secured by a blanket lien on eligible real estate secured loans. These borrowings were utilized to support strong asset growth during 2015.

At December 31, 2015,2018, long-term borrowings increased $97.6$23.0 million compared to December 31, 2017 due to a $25.0 million, two year, fixed rate FHLB advance booked in December 2018. Short-term borrowings decreased $70.0 million as compared to December 31, 2014 as a result of shifting $100 million of short-term borrowings2017 primarily due to a long-term variable rate borrowing in the second quarter of 2015.reduced funding needs. At December 31, 2015,2018, our long-term borrowings outstanding of $117.0$70.3 million included $13.9$32.2 million that were at a fixed rate and $103.1$38.1 million at a variable rate.
During the third quarter ofIn 2006, we issued $25.0 million of junior subordinated debentures through a pooled transaction at an initial fixed rate of 6.78 percent. Beginning September 15, 2011 and quarterly thereafter, we have had the option to redeem the subordinated debt, subject to a 30 day written notice and prior approval by the FDIC. The subordinated debt converted to a variable rate of three-month LIBOR plus 160 basis points in September of 2011. The subordinated debt qualifies as Tier 2 capital under regulatory guidelines and will mature on December 15, 2036.
During the first quarter ofIn 2008, we completed a private placement to a financial institution of $20.0 million of floating rate trust preferred securities. The trust preferred securities mature in March 2038, are callable at our option after five years and had an interest rate initially at a rate of 6.44 percent per annum and adjusts quarterly with the three-month LIBOR plus 350 basis points. We began making interest payments to the trustee on June 15, 2008 and quarterly thereafter. The trust preferred securities qualify as Tier 1 capital under regulatory guidelines. To issue these trust preferred securities, we formed STBA Capital Trust I, or the Trust, with $0.6 million of common equity, which is owned 100 percent by us. The proceeds from the sale of the trust preferred securities and the issuance of common equity were invested by the Trust in junior subordinated debt issued by us, which is the sole asset of the Trust. The Trust pays dividends on the trust preferred securities at the same rate as the interest we pay on the junior subordinatesubordinated debt held by the Trust. Because the third-party investors are the primary beneficiaries, the Trust qualifies as a variable interest entity, but is not consolidated in our financial statements.
On March 4, 2015 we assumed a $13.5 million junior subordinated debt from the Integrity acquisition. On March 5, 2015, we paid off $8.5 million and on June 18, 2015, we paid off the remaining $5.0 million.
Wealth Management Assets
As of December 31, 2015, the fair value of the S&T Bank Wealth Management assets under management, or AUM, and administration, which are not accounted for as part of our assets, increased to $2.1 billion from $2.0 billion as of December 31, 2014. AUM consist of $1.1 billion in S&T Trust, $0.5 billion in S&T Financial Services and $0.5 billion in Stewart Capital Advisors. The increase in 2015 is primarily attributable to new business.
Explanation of Use of Non-GAAP Financial Measures
In addition to the results of operations presented in accordance with GAAP, our management uses, and this Report contains or references, certain non-GAAP financial measures, such as net interest income on a FTE basis, operating revenue and the efficiency ratio. We believe these non-GAAP financial measures provide information useful to investors in understanding our underlying operational performance and our business and performance trends as they facilitate comparisons with the performance of other companies in the financial services industry. Although we believe that these non-GAAP financial measures enhance investors’ understanding of our business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP or considered to be more important than financial results determined in accordance with GAAP, nor is it necessarily comparable with non-GAAP measures which may be presented by other companies.
We believe the presentation of net interest income on a FTE basis ensures comparability of net interest income arising from both taxable and tax-exempt sources and is consistent with industry practice. Interest income per the Consolidated Statements of Net Income is reconciled to net interest income adjusted to a FTE basis on pages 26 and 32.
Operating revenue is the sum of net interest income plus noninterest income, excluding security gains/losses and non-recurring income and expenses. In order to understand the significance of net interest income to our business and operating results, we believe it is appropriate to evaluate the significance of net interest income as a component of operating revenue.
The efficiency ratio is recurring noninterest expense divided by recurring noninterest income plus net interest income, on a FTE basis, which ensures comparability of net interest income arising from both taxable and tax-exempt sources and is consistent with industry practice.
Common return on average tangible assets, common return on average tangible common equity and the ratio of tangible common equity to tangible assets exclude goodwill, other intangible assets and preferred equity in order to show the significance of the tangible elements of our assets and common equity. Total assets and total average assets are reconciled to total tangible assets and total tangible average assets on page 19. Total shareholders equity and total average shareholders equity are also reconciled to total tangible common equity and total tangible average common equity on page 19. These measures are consistent with industry practice.

Wealth Management Assets
As of December 31, 2018, the fair value of the S&T Bank Wealth Management assets under administration, which are not accounted for as part of our assets, decreased to $1.8 billion from $2.0 billion as of December 31, 2017. Assets under administration consisted of $0.9 billion in S&T Trust, $0.6 billion in S&T Financial Services and $0.3 billion in Stewart Capital Advisors.
Capital Resources
Shareholders’ equity increased $183.8$51.8 million, or 30.25.9 percent, to $792.2$935.8 million at December 31, 20152018 compared to $608.4$884.0 million at December 31, 2014.2017. The increase in shareholders’ equity iswas primarily due to $142.5 million of common stock issued in the Merger and net income exceedingof $105.3 million offset partially by dividends by $42.6of $34.5 million for 2015. Included in other comprehensive income (loss) was a decreaseand share repurchases of $2.6 million due to the adjustment in the funded status of the employee benefit plans due to asset performance and by the change in unrealized gains on securities available-for-sale, due to the decline in interest rates at the end of the year.$12.3 million.
We continue to maintain a strongour capital position with a leverage ratio of 8.9610.05 percent as compared to the regulatory guideline of 5.00 percent to be well capitalizedwell-capitalized and a risk-based Common Equity Tier 1 ratio of 9.7711.38 percent compared to the regulatory guideline of 6.50 percent to be well capitalized.well-capitalized. Our risk-based Tier 1 and Total capital ratios were 10.1511.72 percent and 11.6013.21 percent, at December 31, 2015, which places us significantly above the federal bank regulatory agencies’ “well capitalized”well-capitalized guidelines of 8.00 percent and 10.00 percent, for Tier 1 and Total capital.respectively. We believe that we have the ability to raise additional capital, if necessary.
In July 2013 the federal banking agencies issued a final rule to implement Basel III (which were agreements reached in July 2010 by the international oversight body of the Basel Committee on Banking Supervision to require more and higher-quality capital) as well asand the minimum leverage and risk-based capital requirements of the Dodd-Frank Act. The final rule establishesestablished a comprehensive capital framework, and went into effect on January 1, 2015 for smaller banking organizations such as S&T and S&T Bank. It introduces a common equity Tier 1 risk-based capital ratio requirement of 4.50 percent, increases the minimum Tier 1 risk-based capital ratio to 6.00 percent, and requires a leverage ratio of 4.00 percent for all banks. Common equity Tier 1 capital consists of common stock instruments that meet the eligibility criteria in the rule, retained earnings, accumulated other comprehensive income and common equity Tier 1 minority interest. The rule also requires a banking organization to maintain a capital conservation buffer composed of common equity Tier 1 capital in an amount greater than 2.50 percent of total risk-weighted assets beginning in 2019. The capital conservation buffer will be phasedis scheduled to phase in beginningover several years. The capital conservation buffer was 0.25 percent in 2016, at 25 percent, increasing to 500.50 percent in 2017, 750.75 percent in 2018, and 100will increase to 1.00 percent in 2019 and beyond. As a result, starting in 2019, a banking organization must maintain a common equity Tiertier 1 risk-based capital ratio greater than 7.00 percent, a Tiertier 1 risk-based capital ratio greater than 8.50 percent, and a Totaltotal risk-based capital ratio greater than 10.50 percent; otherwise, it will be subject to restrictions on capital distributions and discretionary bonus payments. By 2019, when the new rule is fully phased in, the minimum capital requirements plus the capital conservation buffer will exceed the regulatory capital ratios required for an insured depository institution to be well-capitalized under the FDIC's prompt corrective action law described below.
The new regulatory capital rule also revises the calculation of risk-weighted assets. It includes a new framework under which the risk weight will increase for most credit exposures that are 90 days or more past due or on nonaccrual, high-volatility commercial real estate loans and certain equity exposures. It also includes changes to the credit conversion factors of off-balance sheet items, such as the unused portion of a loan commitment..
Federal regulators periodically propose amendments to the regulatory capital rules and the related regulatory framework and consider changes to the capital standards that could significantly increase the amount of capital needed to meet applicable standards. The timing of adoption, ultimate form and effect of any such proposed amendments cannot be predicted.
In October 2015, weWe have filed a new shelf registration statement on Form S-3 under the Securities Act of 1933 as amended, with the SEC, to replace the prior shelf registration statement we had filed in October 2012. The new shelf registration statementwhich allows for the issuance of a variety of securities including debt and capital securities, preferred and common stock and warrants. We may use the proceeds from the sale of securities for general corporate purposes, which could include investments at the holding company level, investing in, or extending credit to our subsidiaries, possible acquisitions and stock repurchases. As of December 31, 2015,2018, we had not issued any securities pursuant to the shelf registration statement.

Operating lease obligations represent short and long-term lease arrangements as described in Note 9 Premises and Equipment, to the Consolidated Financial Statements included in Part II, Item 8 Note 10 Premises and Equipment, in the Notes to Consolidated Financial Statements.of this Report. Purchase obligations primarily represent obligations under agreement with our third party data processing servicer and communications charges as described in Note 17 Commitments and Contingencies, to the Consolidated Financial Statements included in Part II, Item 8 Note 18 Commitments and Contingencies, of this Report.
Off-Balance Sheet Arrangements
In the normal course of business, we offer off-balance sheet credit arrangements to enable our customers to meet their financing objectives. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the financial statements. Our exposure to credit loss, in the event the customer does not satisfy the terms of the agreement, equals the contractual amount of the obligation less the value of any collateral. We apply the same credit policies in making commitments and standby letters of credit that are used for the underwriting of loans to customers. Commitments generally have fixed expiration dates, annual renewals or other termination clauses and may require payment of a fee. Because many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.
The following table sets forth the commitments and letters of credit as of December 31:

Liquidity
Liquidity is defined as a financial institution’s ability to meet its cash and collateral obligations at a reasonable cost. This includes the ability to satisfy the financial needs of depositors who want to withdraw funds or of borrowers needing to access funds to meet their credit needs. In order to manage liquidity risk our Board of Directors has delegated authority to the ALCO for formulation, implementation and oversight of liquidity risk management for S&T. The ALCO’s goal is to maintain adequate levels of liquidity at a reasonable cost to meet funding needs in both a normal operating environment and for potential liquidity stress events. The ALCO monitors and manages liquidity through various ratios, reviewing cash flow projections, performing stress tests, and by having a detailed contingency funding plan. The ALCO policy guidelines define graduated risk tolerance levels. If our liquidity position moves to a level that has been defined as high risk, specific actions are required, such as increased monitoring or the development of an action plan to reduce the risk position.
Our primary funding and liquidity source is a stable customer deposit base. We believe S&T Bank has the ability to retain existing and attract new deposits, mitigating any funding dependency on other more volatile sources. Refer to the Deposits Sectionsection of this Part II, Item 7, MD&A for additional discussion on deposits. Although deposits are the primary source of funds, we have identified various other funding sources that can be used as part of our normal funding program when either a structure or cost efficiency has been identified. Additional funding sources accessible to S&T include borrowing availability at the FHLB of Pittsburgh, Federal Funds lines with other financial institutions, the brokered deposit market, and borrowing availability through the Federal Reserve Borrower-In-Custody program.
An important component of S&T’sour ability to effectively respond to potential liquidity stress events is maintaining a cushion of highly liquid assets. Highly liquid assets are those that can be converted to cash quickly, with little or no loss in value, to meet financial obligations. ALCO policy guidelines define a ratio of highly liquid assets to total assets by graduated risk tolerance levels of minimal, moderate, and high. At December 31, 2015 S&T Bank2018, we had $442.8$529 million in highly liquid assets, which consisted of $41.2$82.6 million in interest-bearing deposits with banks, $366.2$444 million in unpledged securities, and $35.3$2.4 million in loans held for sale. TheThis resulted in a highly liquid assets to total assets resulted in an asset liquidity ratio of 7.07.3 percent at December 31, 2015.2018. Also, at December 31, 2015,2018, we had a remaining borrowing availability of $1.4$1.8 billion with the FHLB of Pittsburgh. Refer to Note 15 Short-term Borrowings and Note 16 Long-Term Borrowings and Subordinated Debt to the Consolidated Financial Statements included in Part II, Item 8, Notes 16 and 17 Short-term and Long-term borrowings,of this Report, and the Borrowings section of this Part II, Item 7, MD&A, for more details.


Inflation
Management is aware of the significant effect inflation has on interest rates and can have on financial performance. Our ability to cope with this is best determined by analyzing our capability to respond to changing interest rates and our ability to manage noninterest income and expense. We monitor the mix of interest-rate sensitive assets and liabilities through ALCO in order to reduce the impact of inflation on net interest income. We also control the effects of inflation by reviewing the prices of our products and services, by introducing new products and services and by controlling overhead expenses.

Item 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is defined as the degree to which changes in interest rates, foreign exchange rates, commodity prices, or equity prices can adversely affect a financial institution’s earnings or capital. For most financial institutions, including S&T, market risk primarily reflects exposures to changes in interest rates. Interest rate fluctuations affect earnings by changing net interest income and other interest-sensitive income and expense levels. Interest rate changes also affect capital by changing the net present value of a bank’s future cash flows, and the cash flows themselves, as rates change. Accepting this risk is a normal part of banking and can be an important source of profitability and enhancing shareholder value. However, excessive interest rate risk can threaten a bank’s earnings, capital, liquidity, and solvency. Our sensitivity to changes in interest rate movements is continually monitored by the ALCO. The ALCO monitors and manages market risk through rate shock analyses, economic value of equity, or EVE, analysisanalyses and by performing stress tests and simulations in order to mitigate earnings and market value fluctuations due to changes in interest rates.
Rate shock analyses results are compared to a base case to provide an estimate of the impact that market rate changes may have on 12 and 24 months of pretax net interest income. The base case and rate shock analyses are performed on a static balance sheet. A static balance sheet is a no growth balance sheet in which all maturing and/or repricing cash flows are reinvested in the same product at the existing product spread. Rate shock analyses assume an immediate parallel shift in market interest rates and also include management assumptions regarding the impact of interest rate changes on non-maturity deposit products (noninterest-bearing demand, interest-bearing demand, money market and savings) and changes in the prepayment behavior of loans and securities with optionality. S&T policy guidelines limit the change in pretax net interest income over a 12 and 24 month horizonhorizons using rate shocks in increments of +/- 300100 basis points. Policy guidelines define the percentpercentage change in pretax net interest income by graduated risk tolerance levels of minimal, moderate, and high. We have temporarily suspendedThroughout the -200 and -300 basis point rate shock analyses. Due to theextended low interest rate environment, we believesuspended the analysis on downward rate shocks of 300 basis points or more. We believed that the impact to net interest income when evaluating the -200 and -300 basis point rate shockthese scenarios doesdid not provide meaningful insight into our interest rate risk position. We reinstated the -200 rate shock in September 2018 because interest rates increased enough for the scenario to become meaningful.
In order to monitor interest rate risk beyond the 1224 month time horizon of rate shocks on pretax net interest income, we also perform EVE analysis.analyses. EVE represents the present value of all asset cash flows minus the present value of all liability cash flows. EVE rate change results are compared to a base case to determine the impact that market rate changes may have on our EVE. As with rate shock analysis,analyses on pretax net interest income, EVE incorporatesanalyses incorporate management assumptions regarding prepayment behavior of fixed rate loans and securities with optionality and the behavior and value of non-maturity deposit products. S&T policy guidelines limit the change in EVE given changesusing rate shocks in ratesincrements of +/- 300100 basis points. Policy guidelines define the percent change in EVE by graduated risk tolerance levels of minimal, moderate, and high. We have also temporarilySimilar to the rate shock analyses, the downward rate shocks of 300 basis points or more had been suspended the EVE -200 and -300 basis point scenarios due to the low interest rate environment.environment, however, we also reinstated the -200 rate shock for EVE in September 2018.
The table below reflects the rate shock analyses results for the 1 - 12 and EVE results. Both13 - 24 month periods of pretax net interest income and EVE. All results are in the minimal risk tolerance level.

The results from the rate shock analyses on net interest income are consistent with having an asset sensitive balance sheet. Having an asset sensitive balance sheet means more assets than liabilities will reprice during the measured time frames. The implications of an asset sensitive balance sheet will differ depending upon the change in market interest rates. For example, with an asset sensitive balance sheet in a declining interest rate environment, more assets than liabilities will decrease in rate.This situation could result in a decrease in net interest income and operating income. Conversely, with an asset sensitive balance sheet in a rising interest rate environment, more assets than liabilities will increase in rate. This situation could result in an increase in net interest income and operating income.As measured by rate shock analyses, an increase in interest rates would have a positive impact on pretax net interest income.
Our rate shock analyses indicate that there was a decline in the percent change in pretax net interest income for our rates up and rates down shock scenarios when comparing December 31, 2015 and December 31, 2014. The decline in the rates up shock scenarios is mainly a result of becoming slightly less asset sensitive due to utilization of short-term funding to support asset growth during the fourth quarter of 2015. The decline in the rates down shock scenario is mainly a result of higher rates on assets in the base case when compared to December 31, 2014. Higher base case asset portfolio rates resulted in a larger decrease in rates before hitting assumed floors.

When comparingOur rate shock analyses show an improvement in the EVE results for December 31, 2015 and December 31, 2014, the percentpercentage change to EVE has decreasedin pretax net interest income in the rates up shockscenarios in months 1 - 12 and a decline in the rates down scenarios when comparing December 31, 2018 to December 31, 2017. In months 13 - 24, the percentage change in pretax net interest income declined in the rates up scenarios and improved in the rates down scenarios when comparing December 31, 2018 and December 31, 2017. These changes are mostly due to model enhancements. All rate down shock scenario. The percentanalyses for both the 1 - 12 and 13 - 24 month periods continue to remain within minimal risk tolerance levels.
Our EVE analyses show a decline in the percentage change toin EVE in our rate shockthe rates up scenarios isand an improvement in the rates down scenario when comparing December 31, 2018 to December 31, 2017. The changes are mainly attributed toa result of deposit valuation enhancements and the change in value of our core deposits due to a lower rate environment.deposits.
In addition to rate shocks and EVE analyses, we perform a market risk stress test at least annually. The market risk stress test includes sensitivity analyses and simulations. Sensitivity analyses are performed to help us identify which model assumptions cause the greatest impact on pretax net interest income. Sensitivity analyses may include changing prepayment behavior of loans and securities with optionality and the impact of interest rate changes on non-maturity deposit products. Simulation analyses may include the potential impact of rate shockschanges other than the policy guidelines, of +/- 300 basis points, yield curve shape changes, significant balance mix changes, and various growth scenarios. SimulationsFor example, simulations indicate that an increase in rates, particularly if the yield curve steepens, will most likely result in an improvement in pretax net interest income. SomeWe realize that some of the benefit reflected in our scenarios may be offset by a change in the competitive environment and a change in product preference by our customers.

(1) Due to the adoption of ASU No. 2016-01, net unrealized gains on marketable equity securities were reclassified from accumulated other comprehensive income to retained earnings during the three months ended March 31, 2018. The prior period data was not restated; as such, the change in unrealized gains on marketable securities is combined with the change in net unrealized gains on debt securities for the prior periods ended December 31, 2017 and 2016.
(2) Reclassification adjustments are comprised of realized security gains or losses. The realized gains or losses have been reclassified out of accumulated other comprehensive income/(loss) and have affected certain lines in the Consolidated Statements of Net Income as follows: the pre-tax amount is included in securities gains/losses-net, the tax expense amount is included in the provision for income taxes and the net of tax amount is included in net income.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
S&T Bancorp, Inc. and Subsidiaries
NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Nature of Operations
S&T Bancorp, Inc., or S&T, was incorporated on March 17, 1983 under the laws of the Commonwealth of Pennsylvania as a bank holding company and has three direct wholly owned subsidiaries, S&T Bank, 9th Street Holdings, Inc. and STBA Capital Trust I. We own a 50 percent interest in Commonwealth Trust Credit Life Insurance Company, or CTCLIC.
We are presently engaged in nonbanking activities through the following five entities: 9th Street Holdings, Inc.; S&T Bancholdings, Inc.; CTCLIC; S&T Insurance Group, LLCLLC; and Stewart Capital Advisors, LLC. 9th Street Holdings, Inc. and S&T Bancholdings, Inc. are investment holding companies. CTCLIC, which is a joint venture with another financial institution, acts as a reinsurer of credit life, accident and health insurance policies sold by S&T Bank and the other institution. S&T Insurance Group, LLC, through its subsidiaries, offers a variety of insurance products. Stewart Capital Advisors, LLC is a registered investment advisor that manages private investment accounts for individuals and institutionsinstitutions.
Prior to 2017, we reported three operating segments: Community Banking, Wealth Management and advisesInsurance. Effective January 1, 2017, we no longer report Wealth Management and Insurance segment information, as they do not meet the Stewart Capital Mid Cap Fund.quantitative thresholds required for disclosure.
On October 29, 2014,January 1, 2018, we sold a 70 percent majority interest in the assets of our wholly-owned subsidiary S&T and Integrity Bancshares, Inc., or Integrity, basedEvergreen Insurance, LLC. We transferred our remaining 30 percent ownership interest in Camp Hill, Pennsylvania, entered into an agreement to acquire Integrity Bancshares, Inc. and the transaction was completed on March 4, 2015. Integrity Bank was subsequently merged into S&T Bank on May 8, 2015. S&T Bank is operating under the name "Integrity Bank - A Divisionnet assets of S&T Bank"Evergreen Insurance, LLC to a new entity for a 30 percent ownership interest in south-central Pennsylvania.a new insurance entity (see Note 26: Sale of a Majority Interest of Insurance Business). We use the equity method of accounting to recognize our partial ownership interest in the new entity.
Accounting Policies
Our financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the dates of the balance sheets and revenues and expenses for the periods then ended. Actual results could differ from those estimates. Our significant accounting policies are described below.
Principles of Consolidation
The Consolidated Financial Statements include the accounts of S&T and its wholly owned subsidiaries. All significant intercompany transactions have been eliminated in consolidation. Investments of 20 percent to 50 percent of the outstanding common stock of investees are accounted for using the equity method of accounting.
Reclassification
Certain amountsAmounts in prior years’years' financial statements and footnotes have beenare reclassified whenever necessary to conform to the current year’s presentation. The reclassificationsReclassifications had no significant effect on our results of operations or financial condition.
Business Combinations
We account for business combinations using the acquisition method of accounting. Under this method of accounting, the acquired company’s net assets are recorded at fair value at the date of acquisition, and the results of operations of the acquired company are combined with our results from that date forward. Acquisition costs are expensed when incurred. The difference between the purchase price and the fair value of the net assets acquired (including identified intangibles) is recorded as goodwill.
Fair Value Measurements
We use fair value measurements when recording and disclosing certain financial assets and liabilities. Securities available-for-sale, trading assetsDebt securities, equity securities and derivative financial instruments are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record other assets at fair value on a nonrecurring basis, such as loans held for sale, impaired loans, other real estate owned, or OREO, and other repossessed assets, mortgage servicing rights, or MSRs, and certain other assets.
Fair value is the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities; it is not a forced transaction. In determining fair value, we use various valuation approaches, including market, income and cost approaches. The fair value standard establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of

60


NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- continued


a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing an asset or liability, which are developed based on market data we have obtained from independent sources. Unobservable inputs reflect our estimates of assumptions that market participants would use in pricing an asset or liability, which are developed based on the best information available in the circumstances.
The fair value hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The fair value hierarchy is broken down into three levels based on the reliability of inputs as follows:
Level 1: valuation is based upon unadjusted quoted market prices for identical instruments traded in active markets.
Level 2: valuation is based upon quoted market prices for similar instruments traded in active markets, quoted market prices for identical or similar instruments traded in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by market data.
Level 3: valuation is derived from other valuation methodologies, including discounted cash flow models and similar techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in determining fair value.
A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our policy is to recognize transfers between any of the fair value hierarchy levels at the end of the reporting period in which the transfer occurred.
The following are descriptions of the valuation methodologies that we use for financial instruments recorded at fair value on either a recurring or nonrecurring basis.
Recurring Basis
Debt Securities Available-for-Sale
Securities available-for-sale include both debt and equity securities. We obtain fair values for debt securities from a third-party pricing service which utilizes several sources for valuing fixed-income securities. We validate prices received from our pricing service through comparison to a secondary pricing service and broker quotes. We review the methodologies of the pricing service which providesprovide us with a sufficient understanding of the valuation models, assumptions, inputs and pricing to reasonably measure the fair value of our debt securities. The market evaluationvaluation sources for debt securities include observable inputs rather than significant unobservable inputs and are classified as Level 2. The service provider utilizes pricing models that vary by asset class and include available trade, bid and other market information. Generally, the methodologies include broker quotes, proprietary models, and vast descriptive terms and conditionscondition databases, as well asand extensive quality control programs.
Equity Securities
Marketable equity securities that have an active, quotable market are classified as Level 1. Marketable equity securities that are quotable, but are thinly traded or inactive, are classified as Level 2. Marketable equity securities that are not readily traded and do not have a quotable market are classified as Level 3.
TradingRabbi Trust Assets
We use quoted market prices to determine the fair value of our tradingequity security assets. Our tradingThese securities are reported at fair value with the gains and losses included in noninterest income in our Consolidated Statements of Net Income. These assets are held in a Rabbi Trust under a deferred compensation plan and are invested in readily quoted mutual funds. Accordingly, these assets are classified as Level 1. Rabbi Trust assets are reported in other assets in the Consolidated Balance Sheets.
Derivative Financial Instruments
We use derivative instruments, including interest rate swaps for commercial loans with our customers, interest rate lock commitments and the sale of mortgage loans in the secondary market. We calculate the fair value for derivatives using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. Each valuation considers the contractual terms of the derivative, including the period to maturity, and uses observable market basedmarket-based inputs, such as interest rate curves and implied volatilities. Accordingly, derivatives are classified as Level 2. We incorporate credit valuation adjustments into the valuation models to appropriately reflect both our own nonperformance risk and the respective counterparties’ nonperformance risk in calculating fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements and collateral postings.

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- continued


Nonrecurring Basis
Loans Held for Sale
Loans held for sale consist of 1-4 family residential loans originated for sale in the secondary market and, from time to time, certain loans transferred from the loan portfolio to loans held for sale, all of which are carried at the lower of cost or fair value. The fair value of 1-4 family residential loans is based on the principal or most advantageous market currently offered for similar loans using observable market data. The fair value of the loans transferred from the loan portfolio is based on the amounts offered for these loans in currently pending sales transactions. Loans held for sale carried at fair value are classified as Level 3.
Impaired Loans
Impaired loans are carried at the lower of carrying value or fair value. Fair value is determined as the recorded investment balance less any specific reserve. We establish specific reserves based on the following three impairment methods: 1) the present value of expected future cash flows discounted at the loan’s original effective interest rate,rate; 2) the loan’s observable market priceprice; or 3) the fair value of the collateral less estimated selling costs when the loan is collateral dependent and we expect to liquidate the collateral. However, if repayment is expected to come from the operation of the collateral, rather than liquidation, then we do not consider estimated selling costs in determining the fair value of the collateral. Collateral values are generally based upon appraisals by approved, independent state certified appraisers. Appraisals may be discounted based on our historical knowledge, changes in market conditions from the time of appraisal or our knowledge of the borrower and the borrower’s business. Impaired loans carried at fair value are classified as Level 3.
OREO and Other Repossessed Assets
OREO and other repossessed assets obtained in partial or total satisfaction of a loan are recorded at the lower of recorded investment in the loan or fair value less cost to sell. Subsequent to foreclosure, these assets are carried at the lower of the amount recorded at acquisition date or fair value less cost to sell. Accordingly, it may be necessary to record nonrecurring fair value adjustments. Fair value, when recorded, is generally based upon appraisals by approved, independent state certified appraisers. Like impaired loans, appraisals on OREO may be discounted based on our historical knowledge, changes in market conditions from the time of appraisal or other information available to us. OREO and other repossessed assets carried at fair value are classified as Level 3.
Mortgage Servicing Rights
The fair value of MSRs is determined by calculating the present value of estimated future net servicing cash flows, considering expected mortgage loan prepayment rates, discount rates, servicing costs and other economic factors, which are determined based on current market conditions. The expected rate of mortgage loan prepayments is the most significant factor driving the value of MSRs. MSRs are considered impaired if the carrying value exceeds fair value. The valuation model includes significant unobservable inputs; therefore, MSRs are classified as Level 3. MSRs are reported in other assets in the Consolidated Balance Sheets and are amortized into noninterest income in the Consolidated Statements of Net Income.
Other Assets
We measure certain other assets at fair value on a nonrecurring basis. Fair value is based on the application of lower of cost or fair value accounting, or write-downs of individual assets. Valuation methodologies used to measure fair value are consistent with overall principles of fair value accounting and consistent with those described above.
Financial Instruments
In addition to financial instruments recorded at fair value in our financial statements, fair value accounting guidance requires disclosure of the fair value of all of an entity’s assets and liabilities that are considered financial instruments. The majority of our assets and liabilities are considered financial instruments. Many of these instruments lack an available trading market as characterized by a willing buyer and willing seller engaged in an exchange transaction. Also, it is our general practice and intent to hold our financial instruments to maturity and to not engage in trading or sales activities with respect to such financial instruments. For fair value disclosure purposes, we substantially utilize the fair value measurement criteria as required and explained above. In cases where quoted fair values are not available, we use present value methods to determine the fair value of our financial instruments.

Cash and Cash Equivalents
The carrying amounts reported in the Consolidated Balance Sheets for cash and due from banks, including interest-bearing deposits, approximate fair value.
Loans
With the adoption of ASU No. 2016-01, Accounting for Financial Instruments - Overall: Classification and Measurement, on January 1, 2018, we refined our methodology to estimate the fair value of our loan portfolio to use the exit price notion as required by the standard. The guidance was applied on a prospective basis resulting in prior periods no longer being comparable.
The fair value of variable rate performing loans that may reprice frequently at short-term market rates is based on carrying values adjusted for liquidity and credit risk. The fair value of variable rate performing loans that reprice at intervals of one year or longer, such as adjustable rate mortgage products, is estimated using discounted cash flow analyses that utilize interest rates currently being offered for similar loans and adjusted for liquidity and credit risk. The fair value of fixed rate performing loans is estimated using a discounted cash flow analysis that utilizes interest rates currently being offered for similar loans and adjusted for liquidity and credit risk. The fair value of impaired nonperforming loans is based on their carrying values less any specific reserve. The carrying amount of accrued interest approximates fair value.
Bank Owned Life Insurance
Fair value approximates net cash surrender value of bank owned life insurance, or BOLI.
Federal Home Loan Bank, or FHLB, and Other Restricted Stock
It is not practical to determine the fair value of our FHLB and other restricted stock due to the restrictions placed on the transferability of these stocks; it is presented at carrying value.
Deposits
The fair values disclosed for deposits without defined maturities (e.g., noninterest and interest-bearing demand, money market and savings accounts) are by definition equal to the amounts payable on demand. The carrying amounts for variable rate, fixed-term time deposits approximate their fair values. Estimated fair values for fixed rate and other time deposits are based on discounted cash flow analysis using interest rates currently offered for time deposits with similar terms. The carrying amount of accrued interest approximates fair value.
Short-Term Borrowings
The carrying amounts of securities sold under repurchase agreements, or REPOs, and other short-term borrowings approximate their fair values.
Long-Term Borrowings
The fair values disclosed for fixed rate long-term borrowings are determined by discounting their contractual cash flows using current interest rates for long-term borrowings of similar remaining maturities. The carrying amounts of variable rate long-term borrowings approximate their fair values.
Junior Subordinated Debt Securities
The interest rate on the variable rate junior subordinated debt securities repriceis reset quarterly; therefore, the carrying values approximate their fair values.
Loan Commitments and Standby Letters of Credit
Off-balance sheet financial instruments consist of commitments to extend credit and letters of credit. Except for interest rate lock commitments, estimates of the fair value of these off-balance sheet items are not made because of the short-term nature of these arrangements and the credit standing of the counterparties.
Other
Estimates of fair value are not made for items that are not defined as financial instruments, including such items as our core deposit intangibles and the value of our trust operations.

Cash and Cash Equivalents
We consider cash and due from banks, interest-bearing deposits with banks and federal funds sold as cash and cash equivalents.
Securities
We determine the appropriate classification of securities at the time of purchase. All securities, including both debt and equityDebt securities are classified as available-for-sale. These are securities that we intendavailable-for-sale with the intent to hold for an indefinite period of time, but that may be sold in response to changes in interest rates, prepayment risk, liquidity needs or other factors. SuchDebt securities are carried at fair value with net unrealized gains and losses deemed to be temporary and reported as a component of other comprehensive income (loss),loss, net of tax. On January 1, 2018, we adopted the new accounting standard for financial instruments, which requires equity securities to be measured at fair value with net unrealized gains and losses recognized in noninterest income on the Consolidated Statements of Net Income. As a result of the adoption of this guidance $0.9 million was reclassified from accumulated other comprehensive income, or AOCI, to retained earnings. Realized gains and losses on the sale of debt securities available-for-sale securities and other-than-temporary impairment, or OTTI, charges are recorded within noninterest income in the Consolidated Statements of Net Income. Realized gains and losses on the sale of these securities are determined using the specific-identification method. Bond premiums are amortized to the call date and bond discounts are accreted to the maturity date, both on a level yield basis.
An investment security is considered impaired if its fair value is less than its cost or amortized cost basis. We perform a quarterly review of our securities to identify those that may indicate an OTTI. Our policy for OTTI within the marketable equity securities portfolio generally requires an impairment charge when the security is in a loss position for 12 consecutive months, unless facts and circumstances would suggest the need for an OTTI prior to that time. Our policy for OTTI within the debt securities portfolio is based upon a number of factors, including but not limited to, the length of time and extent to which the estimated fair value has been less than cost, the financial condition of the underlying issuer, the ability of the issuer to meet contractual obligations, the best estimate of the impairment charge representing credit losses, the likelihood of the security’s ability to recover any decline in its estimated fair value and whether management intends to sell the security or if it is more likely than not that management will be required to sell the investment security prior to the security’s recovery of any decline in its estimated fair value. If the impairment is considered other-than-temporary based on management’s review, the impairment must be separated into credit and non-credit components. The credit component is recognized in the Consolidated Statements of Net Income and the non-credit component is recognized in other comprehensive income (loss),loss, net of applicable taxes.
Loans Held for Sale
Loans held for sale consist of 1-4 family residential loans originated for sale in the secondary market and, from time to time, certain loans transferred from the loan portfolio to loans held for sale, all of which are carried at the lower of cost or fair value. If a loan is transferred from the loan portfolio to the held for sale category, any write-down in the carrying amount of the loan at the date of transfer is recorded as a charge-off against the allowance for loan losses, or ALL. Subsequent declines in fair value are recognized as a charge to noninterest income. When a loan is placed in the held for sale category, we stop amortizing the related deferred fees and costs. The remaining unamortized fees and costs are recognized as part of the cost basis of the loan at the time it is sold. Gains and losses on sales of loans held for sale are included in other noninterest income in the Consolidated Statements of Net Income.
Loans
Loans are reported at the principal amount outstanding net of unearned income, unamortized premiums or discounts and deferred origination fees and costs. We defer certain nonrefundable loan origination and commitment fees. Accretion of discounts and amortization of premiums on loans are included in interest income in the Consolidated Statements of Net Income. Loan origination fees and direct loan origination costs are deferred and amortized as an adjustment of loan yield over the respective lives of the loans without consideration of anticipated prepayments. If a loan is paid off, the remaining unaccreted or unamortized net origination fees and costs are immediately recognized into income or expense. Interest is accrued and interest income is recognized on loans as earned.
Acquired loans are recorded at fair value on the date of acquisition with no carryover of the related ALL. Determining the fair value of the acquired loans involves estimating the principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. In estimating the fair value of our acquired loans, we consider a number of factors including the loan term, internal risk rating, delinquency status, prepayment rates, recovery periods, estimated value of the underlying collateral and the current interest rate environment.
Closed-end installment loans, amortizing loans secured by real estate and any other loans with payments scheduled monthly are reported past due when the borrower is in arrears two or more monthly payments. Other multi-payment obligations with payments scheduled other than monthly are reported past due when one scheduled payment is due and unpaid for 30 days or more.

64


NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- continued


Generally, consumer loans are charged off against the ALL upon the loan reaching 90 days past due. Commercial loans are charged off as management becomes aware of facts and circumstances that raise doubt as to the collectability of all or a portion of the principal and when we believe a confirmed loss exists.

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- continued


Nonaccrual or Nonperforming Loans
We stop accruing interest on a loan when the borrower’s payment is 90 days past due. Loans are also placed on nonaccrual status when payment is not past due, but we have doubt about the borrower’s ability to comply with contractual repayment terms.terms, even if payment is not past due. When the interest accrual is discontinued, all unpaid accrued interest is reversed against interest income. Interest income is recognized on nonaccrual loans on a cash basis if recovery of the remaining principal is reasonably assured. As a general rule, a nonaccrual loan may be restored to accrual status when its principal and interest is paid current and the bank expects repayment of the remaining contractual principal and interest, or when the loan otherwise becomes well secured and in the process of collection.
Troubled Debt Restructurings
Troubled debt restructurings, or TDRs, are loans where we, for economic or legal reasons related to a borrower’s financial difficulty,difficulties, grant a concession to the borrower that we would not otherwise grant.borrower. We strive to identify borrowers inwith financial difficulty early and work with them to come to a mutual resolution to modify the terms of their loan before theirthe loan reaches nonaccrual status. These modified terms generally include extensions of maturity dates at a stated interest rate lower than the current market rate for a new loan with similar risk characteristics, reductions in contractual interest rates or principal deferment. While unusual, there may be instances of principal forgiveness. These modifications are generally for longer term periods that would not be considered insignificant. Additionally, we classify loans where the debt obligation has been discharged through a Chapter 7 Bankruptcy and not reaffirmed as TDRs.
We individually evaluate all substandard commercial loans that have experienced a forbearance or change in terms agreement, as well asand all substandard consumer and residential mortgage loans that entered into an agreement to modify their existing loan, to determine if they should be designated as TDRs.
All TDRs are considered to be impaired loans and will be reported as impaired loans for the remaining life of the loan, unless the restructuring agreement specifies an interest rate equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk and it is fully expected that the remaining principal and interest will be collected according to the restructured agreement. Further, all impaired loans are reported as nonaccrual loans unless the loan is a TDR that has met the requirements to be returned to accruing status. TDRs can be returned to accruing status if the ultimate collectability of all contractual amounts due, according to the restructured agreement, is not in doubt and there is a period of a minimum of six months of satisfactory payment performance by the borrower either immediately before or after the restructuring.
Allowance for Loan Losses
The ALL reflects our estimates of probable credit losses inherent inwithin the loan portfolio atas of the balance sheet date.date, and it is presented as a reserve against loans in the Consolidated Balance Sheets. Determination of an appropriate ALL is inherently subjective and may be subject to significant changes from period to period. The methodology for determining the ALL has two main components: evaluation and impairment tests of individual loans and evaluation and impairment tests of certain groups of homogeneous loans with similar risk characteristics.
A loan isLoans are considered to be impaired when based upon current information and events it is probable that we will be unable to collect all principal and interest payments due according to the original contractual terms of the loan agreement. We individually evaluate all substandard and nonaccrual commercial loans greater than $0.5 million for impairment. TDRsA TDR will be reported as an impaired loan for the remaining life of the loan, unless the restructuring agreement specifies an interest rate equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk and it is fully expected that the remaining principal and interest will be fully collected according to the restructured agreement. For all TDRs, regardless of size, as well as alleach TDR or other impaired loans,loan, we conduct further analysis to determine the probable loss and assign a specific reserve to the loan if deemed appropriate. Specific reserves are established based uponon the following three impairment methods: 1) the present value of expected future cash flows discounted at the loan’s original effective interest rate,rate; 2) the loan’s observable market priceprice; or 3) the estimated fair value of the collateral ifless estimated selling costs when the loan is collateral dependent.dependent and we expect to liquidate the collateral. Our impairment evaluations consist primarily of the fair value of collateral method because most of our loans are collateral dependent. Collateral values are discounted to consider disposition costs when appropriate. A specific reserve is established or a charge-off is taken if the fair value of the impaired loan is less than the recorded investment in the loan balance.
The ALL for homogeneous loans is calculated using a systematic methodology with both a quantitative and a qualitative analysis that is applied on a quarterly basis. The ALL model is comprised of five distinct portfolio segments: 1) Commercial Real Estate, or CRE, 2) Commercial and Industrial, or C&I, 3) Commercial Construction, 4) Consumer Real Estate and 5) Other Consumer. Each segment has a distinct set of risk characteristics monitored by management. We further assess and monitor risk and performance at a more disaggregated level which includes our internal risk rating system for the commercial segments and type of collateral, lien position and loan-to-value, or LTV, for the consumer segments.

65


NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- continued


We first apply historical loss rates to pools of loans with similar risk characteristics. Loss rates are calculated by historical charge-offs that have occurred within each pool of loans over the loss emergence period, or LEP. The LEP is an estimate of the average amount of time from when an event happens that causes the borrower to be unable to pay on a loan until the loss is confirmed through a loan charge-off.
In conjunction with our annual review of the ALL assumptions, we have updated our analysis of LEPs for our Commercial and Consumer loan portfolio segments using our loan charge-off history. The analysis showed that theNo changes were made to our LEP for our C&I, has shortened and our CRE, and Commercial Construction portfolio segments have not changed.assumptions in 2018. We estimate the LEP to be 23 years for C&I, compared to 2.5 years in the prior year, and 3.5CRE, 4 years for both CREconstruction and Commercial Construction.1.25 years for C&I. Our analysis showedresulted in an LEP for Consumer Real Estate of 3.52.75 years and Other Consumer of 1.25 years. This compares to 2 years for both Consumer Real Estate and Other Consumer in the prior year when peer data was being utilized to estimate the LEP. We believe that our actual experience captured through our internal analysis better reflects the inherent risk in these portfolios compared to the peer data used in prior years.
Another key assumption is the look-back period, or LBP, which represents the historical data period utilized to calculate loss rates. We lengthened the LBP for all Commercial and Consumer portfolio segments in order to capture relevant historical data believed to be reflective of losses inherent in the portfolios. We use 6.5used 9.25 years for our LBP for all portfolio segments which encompasses our loss experience during the Great RecessionFinancial Crisis, and our more recent improved loss experience.
After consideration of the historic loss calculations, management applies additional qualitative adjustments so that the ALL is reflective of the inherent losses that exist in the loan portfolio at the balance sheet date. The following qualitative factorsQualitative adjustments are consideredmade based upon changes in lending policies and practices, economic conditions, changes in the ALL:
1)Changes in our lending policies and procedures, including underwriting standards, collection, charge-off and recovery practices not considered elsewhere in estimating credit losses;
2)Changes in national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments;
3)Changes in the nature and volume of our loan portfolio and terms of loans;
4)Changes in the experience, ability and depth of our lending management and staff;
5)Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans;
6)Changes in the quality of our loan review system;
7)Changes in the value of the underlying collateral for collateral-dependent loans;
8)The existence and effect of any concentrations of credit and changes in the level of such concentrations; and
9)The effect of external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in our current loan portfolio.

loan portfolio, changes in lending management, results of internal loan reviews, asset quality trends, collateral values, concentrations of credit risk and other external factors. The changes made to the ALL assumptions were applied prospectively and did not result in a material change to the total ALL. Lengthening the LBP does increase the historical loss rates and therefore the quantitative componentevaluation of the ALL. We believe this makes the quantitative componentvarious components of the ALL more reflectiverequires considerable judgment in order to estimate inherent loss exposures.
Acquired loans are recorded at fair value on the date of inherent losses that exist withinacquisition with no carryover of the related ALL. Determining the fair value of acquired loans involves estimating the principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. In estimating the fair value of our acquired loans, we considered a number of factors including the loan portfolio, which resulted in a decrease in the qualitative componentterm, internal risk rating, delinquency status, prepayment rates, recovery periods, estimated value of the ALL. underlying collateral and the current interest rate environment.
Loans acquired with evidence of credit deterioration were evaluated and not considered to be significant. The premium or discount estimated through the loan fair value calculation is recognized into interest income on a level yield or straight-line basis over the remaining contractual life of the loans. Additional credit deterioration on acquired loans, in excess of the original credit discount embedded in the fair value determination on the date of acquisition, will be recognized in the ALL through the provision for loan losses.
Our ALL Committee meets quarterly to verify the overall adequacyappropriateness of the ALL. Additionally, on an annual basis, the ALL Committee meets to validate our ALL methodology. This validation includes reviewing the loan segmentation, LEP, LBP and the qualitative framework. As a result of this ongoing monitoring process, we may make changes to our ALL to be responsive to the economic environment.
Although we believe our process for determining the ALL appropriately considers all of the factors that would likely result in credit losses, the process includes subjective elements and may be susceptible to significant change. To the extent actual losses are higher than management estimates, additional provisions for loan losses could be required and could adversely affect our earnings or financial position in future periods.
Bank Owned Life Insurance
We have purchased life insurance policies on certain executive officers and employees. We receive the cash surrender value of each policy upon its termination or benefits are payable to us upon the death of the insured. Changes in net cash surrender value are recognized in noninterest income or expense in the Consolidated Statements of Net Income.

Premises and Equipment
Premises and equipment, including leasehold improvements, are stated at cost less accumulated depreciation. Maintenance and repairs are charged to expense as incurred, while improvements that extend an asset’s useful life are capitalized and depreciated over the estimated remaining life of the asset. Depreciation expense is computed by the straight-line method for financial reporting purposes and accelerated methods for income tax purposes over the estimated useful lives of the particular assets. Management reviews long-lived assets using events and circumstances to determine if and when an asset is evaluated for recoverability.

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- continued


The estimated useful lives for the various asset categories are as follows:
1)     Land and Land Improvements Non-depreciating assets
2)     Buildings 25 years
3)     Furniture and Fixtures 5 years
4)     Computer Equipment and Software 5 years or term of license
5)     Other Equipment 5 years
6)     Vehicles 5 years
7)     Leasehold Improvements Lesser of estimated useful life of the asset (generally 15 years unless established otherwise) or the remaining term of the lease, including renewal options in the lease that are reasonably assured of exercise
Restricted Investment in Bank Stock
Federal Home Loan Bank, or FHLB stock is carried at cost and evaluated for impairment based on the ultimate recoverability of the par value. We hold FHLB stock because we are a member of the FHLB of Pittsburgh. The FHLB requires members to purchase and hold a specified level of FHLB stock based upon on the membersmember's asset value, level of borrowings and participation in other programs offered. Stock in the FHLB is non-marketable and is redeemable at the discretion of the FHLB. Members do not purchase stock in the FHLB for the same reasons that traditional equity investors acquire stock in an investor-owned enterprise. Rather, members purchase stock to obtain access to the low-cost products and services offered by the FHLB. Unlike equity securities of traditional for-profit enterprises, the stock of the FHLB does not provide its holders with an opportunity for capital appreciation because, by regulation, FHLB stock can only be purchased, redeemed and transferred at par value. Both cash and stock dividends are reported as income in taxable investment securities in the Consolidated Statements of Net Income. FHLB stock is evaluated for OTTI on a quarterly basis.
Atlantic Community Bankers’ Bank, or ACBB, stock is carried at cost and evaluated for impairment based on the ultimate recoverability of the carrying value. We do not currently use their membership products and services. We acquired ACBB stock through various mergers of banks that were ACBB members. ACBB stock is evaluated for OTTI on a quarterly basis.
Goodwill and Other Intangible Assets
As a result of acquisitions, we have recorded goodwill and identifiable intangible assets in our Consolidated Balance Sheets. Goodwill represents the excess of the purchase price over the fair value of net assets acquired. We account for business combinations using the acquisition method of accounting.
We have three reporting units: Community Banking,Bank, Insurance and Wealth Management. At December 31, 2015, we hadExisting goodwill of $291.8 million, including $287.6 millionrelates to value inherent in the Community Banking representing 99 percentreporting unit and that value is dependent upon our ability to provide quality, cost-effective services in the face of totalcompetition from other market participants. This ability relies upon continuing investments in processing systems, the development of value-added service features and the ease of use of our services. As such, goodwill and $4.2 millionvalue is supported ultimately by profitability that is driven by the volume of business transacted. A decline in Insurance, representing one percentearnings as a result of total goodwill. a lack of growth or the inability to deliver cost-effective services over sustained periods can lead to impairment of goodwill, which could adversely impact our earnings in future periods.
The carrying value of goodwill is tested annually for impairment each October 11st or more frequently if it is determined that we should do so.a triggering event has occurred. We first assess qualitatively whether it is more likely than not that the fair value of athe reporting unit is less than its carrying amount. Our qualitative assessment considers such factors as macroeconomic conditions, market conditions specifically related to the banking industry, our overall financial performance and various other factors. If we determine that it is more likely than not that the fair value is less than the carrying amount, we proceed to test for impairment. The evaluation for impairment involves comparing the current estimated fair value of each reporting unit to its carrying value, including goodwill. If the current estimated fair value of athe reporting unit exceeds its carrying value, no additional testing is required and an impairment loss is not recorded. If the estimated fair value of a reporting unit is less than the carrying value, further valuation procedures are performed andthat could result in impairment of goodwill being recorded. Further valuation procedures would include allocating the estimated fair value to all assets and liabilities of the reporting unit to determine an implied goodwill value. If the implied value of goodwill of a reporting unit is less than the carrying amount of that goodwill, an impairment loss is recognized in an amount equal to that excess. We completed the annual goodwill impairment assessment as required in 2018, 2017 and 2016; the results indicated that the fair value each reporting unit exceeded the carrying value.
We have core deposit and other intangible assets resulting from acquisitions which are subject to amortization. We determine the amount of identifiable intangible assets based upon independent core deposit and insurance contract analysesvaluations at the time of the acquisition. Intangible assets with finite useful lives, consisting primarily of core deposit and customer list intangibles, are amortized using straight-line or accelerated methods over their estimated weighted average useful lives, ranging from 10 to 20 years.
Intangible assets with finite useful lives are evaluated for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable.

67


NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- continued


indicate that their carrying amount may not be recoverable. No such events or changes in circumstances occurred during the years ended December 31, 2018, 2017 and 2016.
The financial services industry and securities markets can be adversely affected by declining values. If economic conditions result in a prolonged period of economic weakness in the future, our operating segments, including the Community Banking segment, may be adversely affected. In the event that we determine that either our goodwill or finite lived intangible assets are impaired, recognition of an impairment charge could have a significant adverse impact on our financial position or results of operations in the period in which the impairment occurs.
Variable Interest Entities
Variable interest entities, or VIEs, are legal entities that generally either do not have equity investors with voting rights or that have equity investors that do not provide sufficient financial resources for the entity to support its activities. When an enterprise has both the power to direct the economic activities of the VIE and the obligation to absorb losses of the VIE or the right to receive benefits of the VIE, the entity has a controlling financial interest in the VIE. A VIE often holds financial assets, including loans or receivables, or other property. The company with a controlling financial interest, the primary beneficiary, is required to consolidate the VIE into its consolidated balance sheets.Consolidated Balance Sheets. S&T has one wholly-owned trust subsidiary, STBA Capital Trust I, or the Trust, for which it does not absorb a majority of expected losses or receive a majority of the expected residual returns. At its inception in 2008, the Trust issued floating rate trust preferred securities to the Trustee, another financial institution, and used the proceeds from the sale to invest in junior subordinated debt issued by us, which is the sole asset of the Trust. The Trust pays dividends on the trust preferred securities at the same rate as the interest we pay on our junior subordinated debt held by the Trust. Because the third-party investors are the primary beneficiaries, the Trust qualifies as a VIE. Accordingly, the Trust and its net assets are not included in our Consolidated Financial Statements. However, the junior subordinated debt issued by S&T is included in our Consolidated Balance Sheets.
Joint Ventures
We have made investments directly in Low Income Housing Tax Credit, or LIHTC, partnerships formed with third parties. As a limited partner in these operating partnerships, we receive tax credits and tax deductions for losses incurred by the underlying properties. These investments are amortized over a maximum of 10 years, which represents the period thatover which the tax credits will be utilized. We have determined that we are not the primary beneficiary of these investments because the general partners have the power to direct the activities that most significantly impact the economic performance of the partnership and have both the obligation to absorb expected losses and the right to receive benefits.
OREO and Other Repossessed Assets
OREO and other repossessed assets are included in other assets in the Consolidated Balance Sheets and are comprised of properties acquired through foreclosure proceedings or acceptance of a deed in lieu of a foreclosure. At the time of foreclosure or acceptance of a deed in lieu of foreclosure, these properties are recorded at the lower of the recorded investment in the loan or fair value less cost to sell. Loan losses arising from the acquisition of any such property initially are charged against the ALL. Subsequently, these assets are carried at the lower of carrying value or current fair value less cost to sell. Gains or losses realized upon disposition of these assets are recorded in other expenses in the Consolidated Statements of Net Income.
Mortgage Servicing Rights
MSRs are recognized as separate assets when commitments to fund a loan to be sold are made. Upon commitment, the MSR is established, which represents the then current estimated fair value of future net cash flows expected to be realized for performing the servicing activities. The estimated fair value of the MSRs is estimated by calculating the present value of estimated future net servicing cash flows, considering expected mortgage loan prepayment rates, discount rates, servicing costs and other economic factors, which are determined based on current market conditions. The expected rate of mortgage loan prepayments is the most significant factor driving the value of MSRs. Increases in mortgage loan prepayments reduce estimated future net servicing cash flows because the life of the underlying loan is reduced. In determining the estimated fair value of MSRs, mortgage interest rates, which are used to determine prepayment rates, are held constant over the estimated life of the portfolio. MSRs are reported in other assets in the Consolidated Balance Sheets and are amortized into noninterest income in the Consolidated Statements of Net Income in proportion to, and over the period of, the estimated future net servicing income of the underlying mortgage loans.
MSRs are regularly evaluated for impairment based on the estimated fair value of those rights. MSRs are stratified by certain risk characteristics, primarily loan term and note rate. If temporary impairment exists within a risk stratification tranche, a valuation allowance is established through a charge to income equal to the amount by which the carrying value exceeds the estimated fair value. If it is later determined that all or a portion of the temporary impairment no longer exists for a particular

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- continued


tranche, the valuation allowance is reduced.
MSRs are also reviewed for OTTI. OTTI exists when the recoverability of a recorded valuation allowance is determined to be remote, taking into consideration historical and projected interest rates and loan pay-off activity. When this situation occurs, the unrecoverable portion of the valuation allowance is applied as a direct write-down to the carrying value of the MSR. Unlike a valuation allowance, a direct write-down permanently reduces the carrying value of the MSR and the valuation allowance, precluding subsequent recoveries.

Derivative Financial Instruments
Interest Rate Swaps
In accordance with applicable accounting guidance for derivatives and hedging, all derivatives are recognized as either assets or liabilities on the balance sheet at fair value. Interest rate swaps are contracts in which a series of interest rate flows (fixed and variable) are exchanged over a prescribed period. The notional amounts on which the interest payments are based are not exchanged. These derivative positions relate to transactions in which we enter into an interest rate swap with a commercial customer while at the same time entering into an offsetting interest rate swap with another financial institution. In connection with each transaction, we agree to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on athe same notional amount at a fixed rate. At the same time, we agree to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows our customer to effectively convert a variable rate loan to a fixed rate loan with us receiving a variable rate. These agreements could have floors or caps on the contracted interest rates.
Pursuant to our agreements with various financial institutions, we may receive collateral or may be required to post collateral based upon mark-to-market positions. Beyond unsecured threshold levels, collateral in the form of cash or securities may be made available to counterparties of interest rate swap transactions. Based upon our current positions and related future collateral requirements relating to them, we believe any effect on our cash flow or liquidity position to be immaterial.
Derivatives contain an element of credit risk, the possibility that we will incur a loss because a counterparty, which may be a financial institution or a customer, fails to meet its contractual obligations. All derivative contracts with financial institutions may be executed only with counterparties approved by our Asset and Liability Committee, or ALCO, and derivatives with customers may only be executed with customers within credit exposure limits approved byin accordance with our Senior Loan Committee.credit policy. Interest rate swaps are considered derivatives, but are not accounted for using hedge accounting. As such, changes in the estimated fair value of the derivatives are recorded in current earnings and included in other noninterest income in the Consolidated Statements of Net Income.
Interest Rate Lock Commitments and Forward Sale Contracts
In the normal course of business, we sell originated mortgage loans into the secondary mortgage loan market. We also offer interest rate lock commitments to potential borrowers. The commitments are generally for a period of 60 days and guarantee a specified interest rate for a loan if underwriting standards are met, but the commitment does not obligate the potential borrower to close on the loan. Accordingly, some commitments expire prior to becoming loans. We canmay encounter pricing risks if interest rates increase significantly before the loan can be closed and sold. We may utilize forward sale contracts in order to mitigate this pricing risk. Whenever a customer desires these products, a mortgage originator quotes a secondary market rate guaranteed for that day by the investor. The rate lock is executed between the mortgagee and us and in turn a forward sale contract may be executed between us and the investor. Both the rate lock commitment and the corresponding forward sale contract for each customer are considered derivatives, but are not accounted for using hedge accounting. As such, changes in the estimated fair value of the derivatives during the commitment period are recorded in current earnings and included in mortgage banking in the Consolidated Statements of Net Income.
Allowance for Unfunded Commitments
In the normal course of business, we offer off-balance sheet credit arrangements to enable our customers to meet their financing objectives. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the financial statements. Our exposure to credit loss, in the event the customer does not satisfy the terms of the agreement, equals the contractual amount of the obligation less the value of any collateral. We apply the same credit policies in making commitments and standby letters of credit that are used for the underwriting of loans to customers. Commitments generally have fixed expiration dates, annual renewals or other termination clauses and may require payment of a fee. Because many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The allowance for unfunded commitments is included in other liabilities in the Consolidated Balance Sheets. The allowance for unfunded commitments is determined using a similar methodology as our ALL methodology. The reserve is calculated by applying historical loss rates and qualitative adjustments to our unfunded commitments.

Treasury Stock
The repurchase of our common stock is recorded at cost. At the time of reissuance, the treasury stock account is reduced using the average cost method. Gains and losses on the reissuance of common stock are recorded in additional paid-in capital, to the extent additional paid-in capital from previous treasury share transactions exists. Any deficiency is charged to retained earnings.

Revenue Recognition - Contracts with Customers
We earn revenue from contracts with our customers when we have completed our performance obligations and recognize revenuesthat revenue when services are provided to our customers. Our contracts with customers are primarily in the form of account agreements. Generally our services are transferred at a point in time in response to transactions initiated and controlled by our customers under service agreements with an expected duration of one year or less. Our customers have the right to terminate their services agreements at any time.
We do not defer incremental direct costs to obtain contracts with customers that would be amortized in one year or less. These costs are primarily salaries and employee benefits recognized as theyexpense in the period incurred.
Service charges on deposit accounts - We recognize monthly service charges for both commercial and personal banking customers based on account fee schedules. Our performance obligation is generally satisfied and the related revenue recognized at a point in time or over time when the services are provided. Other fees are earned based on contractual termsspecific transactions or customer activity within the customers' deposit accounts. These are earned at the time the transaction or customer activity occurs.
Debit and credit card services - Interchange fees are earned whenever debit and credit cards are processed through third-party card payment networks. ATM fees are based on transactions by our customers' and other customers' use of our ATMs or other ATMs. Debit and credit card revenue is recognized at a point in time when the transaction is settled. Our performance obligation to our customers is generally satisfied and the related revenue is recognized at a point in time when the service is provided. Third-party service contracts include annual volume and marketing incentives which are recognized over a period of twelve months when we meet thresholds as stated in the service contract.
Wealth management services - Wealth management services is primarily comprised of fees earned from the management and administration of trusts, assets under administration, brokerage and other financial advisory services. Generally, wealth management fees are earned over a period of time between monthly and annually, per the related fee schedules. Our performance obligations with our customers are generally satisfied when we provide the services as stated in the customers' agreements. The fees are based on a fixed amount or a scale based on the level of services provided or amount of assets under management.
Other fee revenue - Other fee revenue includes a variety of other traditional banking services such as, electronic banking fees, letters of credit origination fees, wire transfer fees, money orders, treasury checks, checksale fees and transfer fees. Our performance obligations are generally satisfied at a point in time, fee revenue is recognized when the services are provided when collectabilityor the transaction is reasonably assured. Our principal source of revenue is interest income, which is recognized on an accrual basis. Interest and dividend income, loan fees, trust fees, fees and charges on deposit accounts, insurance commissions and other ancillary income related to our deposits and lending activities are accrued as earned.settled.
Wealth Management Fees
Assets held in a fiduciary capacity by theour subsidiary bank, S&T Bank, are not our assets and are therefore not included in our Consolidated Financial Statements. Wealth management fee income is reported in the Consolidated Statements of Net Income on an accrual basis.
Stock-Based Compensation
Stock-based compensation may include stock options and restricted stock which is measured using the fair value method of accounting. The grant date fair value is recognized over the period during which the recipient is required to provide service in exchange for the award. Stock option expense is determined utilizing the Black-Scholes model. RestrictedCompensation expense for time-based restricted stock expense is determined usingrecognized ratably over the period of service, generally the entire vesting period, based on fair value on the grant datedate. Compensation expense for performance-based restricted stock is recognized ratably over the remaining vesting period once the likelihood of meeting the performance measure is probable, based on the fair value.value on the grant date. We estimate expected forfeitures when stock-based awards are granted and record compensation expense only for awards that are expected to vest.

Pensions
The expense for S&T Bank’s qualified and nonqualified defined benefit pension plans is actuarially determined using the projected unit credit actuarial cost method. It requires us to make economic assumptions regarding future interest rates and asset returns as well asand various demographic assumptions. We estimate the discount rate used to measure benefit obligations by applying the projected cash flow for future benefit payments to a yield curve of high-quality corporate bonds available in the marketplace and by employing a model that matches bonds to our pension cash flows. The expected return on plan assets is an estimate of the long-term rate of return on plan assets, which is determined based on the current asset mix and estimates of return by asset class. We recognize in the Consolidated Balance Sheets an asset for the plan’s overfunded status or a liability for the plan’s underfunded status. Gains or losses related to changes in benefit obligations or plan assets resulting from experience different from that assumed are recognized as other comprehensive income (loss) in the period in which they occur. To the extent that such gains or losses exceed ten percent of the greater of the projected benefit obligation or plan assets, they are recognized as a component of pension costs over the future service periods of actively employed plan participants. The funding policy for the qualified plan is to contribute an amount each year that is at least equal to the minimum required contribution as determined under the Pension Protection Act of 2006 and the Bipartisan Budget Act of 2015, but not more than the maximum amount permissible for taxable plan sponsors. Our nonqualified plans are unfunded.
On January 25, 2016, the Board of Directors approved an amendment to freeze benefit accruals under the qualified and nonqualified defined benefit pension plans effective March 31, 2016. As a result, no additional benefits are earned by participants in those plans based on service or pay after March 31, 2016. The plan was previously closed to new participants effective December 31, 2007.
Marketing Costs
We expense all marketing-related costs, including advertising costs, as incurred.
Income Taxes
We estimate income tax expense based on amounts expected to be owed to the tax jurisdictions where we conduct business. On a quarterly basis, management assesses the reasonableness of our effective tax rate based upon our current estimate of the amount and components of net income, tax credits and the applicable statutory tax rates expected for the full year. We classify interest and penalties as an element of tax expense.
Deferred income tax assets and liabilities are determined using the asset and liability method and are reported in other assets or other liabilities, as appropriate, in the Consolidated Balance Sheets. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities and recognizes enacted changes in tax rate and laws. When deferred tax assets are recognized, they are subject to a valuation allowance based on management’s judgment as to whether realization is more likely than not.
Accrued taxes represent the net estimated amount due to taxing jurisdictions and are reported in other assets or other liabilities, as appropriate, in the Consolidated Balance Sheets. We evaluate and assess the relative risks and appropriate tax treatment of transactions and filing positions after considering statutes, regulations, judicial precedent and other information and maintain tax accruals consistent with the evaluation of these relative risks and merits. Changes to the estimate of accrued taxes occur periodically due to changes in tax rates, interpretations of tax laws, the status of examinations being conducted by taxing authorities and changes to statutory, judicial and regulatory guidance. These changes, when they occur, can affect

deferred taxes and accrued taxes, as well asand the current period’s income tax expense and can be significant to our operating results.
In the fourth quarter 2017, H.R.1, known as the Tax Cuts and Jobs Act, or Tax Act, was signed into law which requires the deferred tax assets and liabilities to be revalued using the 21 percent federal tax rate enacted. The effect was recorded in our fourth quarter tax provision in 2017.
In the first quarter 2018, we elected to reclassify the income tax effects of the Tax Act from accumulated other comprehensive income to retained earnings.
Tax positions are recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50 percent likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.

Earnings Per Share
Basic earnings per share, or EPS, is calculated using the two-class method to determine income allocated to common shareholders. Unvested share-based payment awards that contain nonforfeitable rights to dividends are considered participating securities under the two-class method. Income allocated to common shareholders is then divided by the weighted average number of common shares outstanding during the period. Potentially dilutive securities are excluded from the basic EPS calculation.
Diluted EPS is calculated under the more dilutive of either the treasury stock method or the two-class method. Under the treasury stock method, the weighted average number of common shares outstanding is increased by the potentially dilutive common shares. For the two-class method, diluted EPS is calculated for each class of shareholders using the weighted average number of shares attributed to each class. Potentially dilutive common shares are common stock equivalents relatingrelated to our outstanding warrants, stock options and restricted stock.

In JanuaryOctober 2016, the FASB issued ASU No. 2016-16, Intra-Entity Transfers of Assets Other Than Inventory. The main objective of this ASU is to require companies to recognize the income tax effects of intercompany sales and transfers of assets other than inventory in the period in which the transfer occurs. This represents a change from previous guidance, which required companies to defer the income tax effects of intercompany transfers of assets until the asset has been sold to an outside party or otherwise recognized. The new guidance requires companies to defer the income tax effects only of intercompany transfers of inventory. This Update was effective for annual periods beginning after December 15, 2017. Early adoption was permitted as of the beginning of an annual period. If an entity chose to early adopt the amendments in the ASU, it had to do so in the first interim period of its annual financial statements.

In April 2015, the FASB issued ASU No. 2015-05, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement. The main provisions of ASU No. 2015-05 provide a basis for evaluating whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, then the arrangement should beloan production offices, which are primarily accounted for as a service contract. The standard is effectiveoperating leases. We have two financing leases both for annual periodsbranch offices. For our financing leases we expect to recognize right-of-use assets and interim periods beginning after December 15, 2015.corresponding liabilities of approximately $1.0 million. For our operating leases we expect to recognize right-of-use assets and corresponding lease liabilities of approximately $33.0 million on our Consolidated Balance Sheets in the first quarter of 2019. We do not expectanticipate that this ASU would have a materialwill impact total assets and total liabilities presented on our resultsConsolidated Balance Sheets; however, we do not believe that it will materially impact our Consolidated Statements of operations or financial position.

The amendments in this ASU require that debt issuance costs relatedupdate permit lessors, as an accounting policy election, to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The standard is required to be adopted by public business entities in annual periods beginning on or after December 15, 2015. In September 2015, the FASB issued ASU No. 2015-15, Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. ASU No. 2015-15 amends the Securities and Exchange Commission (SEC) Content in Subtopic 835-30 by adding SEC paragraph 835-30-S35-1, Interest--Imputation of Interest Subsequent Measurement and paragraph 830-30-S45-1, Other Presentation Matters. These paragraphs were added because ASU No. 2015-03 issued in April 2015 does not address presentation or subsequent measurement of debt issuance costs related to "line-of-credit arrangements." We do not expect that these ASU amendments would have a material impact on our results of operations or financial position.
Consolidation: Amendments to the Consolidation Analysis
In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. The amendments in this ASU affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. All legal entitiessales taxes and other similar taxes are subject to reevaluation under the revised consolidation model. Specifically, the amendments: 1) modify the evaluation of whether limited partnerships and similar legal entities are VIEslessor costs or voting interest entities, 2) eliminate the presumption that a general partner should consolidate a limited partnership, 3) affect the consolidation analysis of reporting entities that are involved with VIEs, particularlylessee costs. Instead, those that have fee arrangements and related party relationships and 4) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2A-7 of the Investment Company Act of 1940 for registered money market funds. The amendments in this ASU are effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. We are currently evaluating the impact that these amendments may have on our consolidated financial statements. We do not expect that this ASU would have a material impact on our results of operations or financial position.

Also, certain lessor costs require lessors to exclude from variable payments, and Unusual Items: Simplifying Income Statement Presentationtherefore revenue, lessor costs paid by Eliminating the Concept of Extraordinary
In January 2015, the FASB issued ASU No. 2015-01, Income Statement – Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary. The amendments inlessees directly to third parties. Our lessor income is immaterial; as such, this ASU No. 2015-01 eliminate from GAAP the concept of extraordinary items and eliminate the requirements for reporting entities to consider whether an underlying event or transaction is extraordinary. The presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that are both unusual in nature and infrequently occurring. The standard is required to be adopted by public business entities in annual periods beginning on or after December 15, 2015. We do not expect that this ASU would have a material impact on our results of operations or financial position.

NOTE 2. BUSINESS COMBINATIONS
On March 4, 2015, we completed the acquisition of 100 percent of the voting shares of Integrity Bancshares, Inc., or Integrity, located in Camp Hill, Pennsylvania, in a tax-free reorganization transaction structured as a merger of Integrity with and into S&T, with S&T being the surviving entity. As a result of the Integrity merger, or the Merger, Integrity Bank, the wholly owned subsidiary bank of Integrity, became a separate wholly owned subsidiary bank of S&T. The merger of Integrity Bank into S&T Bank, with S&T Bank surviving the merger, and related system conversion occurred on May 8, 2015.
Integrity shareholders were entitled to elect to receive for each share of Integrity common stock either $52.50 in cash or 2.0627 shares of S&T common stock subject to allocation and proration procedures in the merger agreement. The total purchase price was approximately $172.0 million which included $29.5 million of cash and 4,933,115 S&T common shares at a fair value of $28.88 per share. The fair value of $28.88 per share of S&T common stock was based on the March 4, 2015 closing price.
The Merger was accounted for under the acquisition method of accounting and our consolidated financial statements include all Integrity Bank transactions from March 4, 2015, until it was merged into S&T Bank on May 8, 2015. The assets acquired and liabilities assumed were recorded at their respective fair values and represent management’s estimates based on available information. Purchase accounting guidance allows for a reasonable period of time following an acquisition for the acquirer to obtain the information necessary to complete the accounting for a business combination. This period is known as the measurement period and shall not exceed one year from the acquisition date. As of December 31, 2015, an additional $1.1 million of purchase accounting adjustments were recognized that increased goodwill. The measurement period adjustments primarily related to a $0.8 million reduction in the fair value of land and $0.3 million to deferred taxes.
Goodwill of $115.9 million was calculated as the excess of the consideration exchanged over the fair value of the identifiable net assets acquired. The goodwill arising from the Merger consists largely of the synergies and economies of scale expected from combining the operations of S&T and Integrity. All of the goodwill was assigned to our Community Banking segment. The goodwill recognized will not be deductible for tax purposes.

Comprehensive Income.

Loans acquired in the Merger were recorded at fair value with no carryover of the related ALL. Determining the fair value of the loans involves estimating the amount and timing of principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. The fair value of the loans acquired was $788.7 million net of a $14.8 million discount. The discount may be accreted to interest income over the remaining contractual life of the loans. Acquired loans included $331.6 million of CRE, $184.2 million of C&I, $92.4 million of commercial construction, $116.9

Direct costs related to the Merger were expensed as incurred. During 2015, we recognized $3.2 million of merger related expenses, including $1.3 million for data processing contract termination and system conversion costs, $1.2 million in legal and professional expenses, $0.4 million in severance payments and $0.3 million in other expenses.

NOTE 3.2. EARNINGS PER SHARE

Diluted earnings per share is calculated using both the two-class and the treasury stock methods with the more dilutive
method used to determine reported diluted earnings per share. The treasury stock method was more dilutive in 2018 and 2017 and was used to determine reported diluted earnings per share. The two-class method was more dilutive in 2016 and was used to determine diluted earnings per share. The following table reconciles the numerators and denominators of basic and diluted EPS:

Table of Contents(1)As reported in the Consolidated Balance Sheets


NOTE 5.4. RESTRICTIONS ON CASH AND DUE FROM BANK ACCOUNTS
The Board of Governors of the Federal Reserve System, or the Federal Reserve, imposes certain reserve requirements on all depository institutions. These reserves are maintained in the form of vault cash or as an interest-bearing balance with the Federal Reserve. The required reserves averaged $44.1$38.8 million for the year ended 2015, $41.82018, $36.2 million for the year ended 20142017 and $39.7$36.8 million for the year ended 2013.2016.
NOTE 6.5. DIVIDEND AND LOAN RESTRICTIONS
S&T is a legal entity separate and distinct from its banking and other subsidiaries. A substantial portion of our revenues consist of dividend payments we receive from S&T Bank. S&T Bank, in turn, is subject to state laws and regulations that limit the amount of dividends it can pay to us. In addition, both S&T and S&T Bank are subject to various general regulatory policies relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. The Federal Reserve has indicated that banking organizations should generally pay dividends only if (i) the organization’s net income available to common shareholders over the past year has been sufficient to fully fund the dividends and (ii) the prospective rate of earnings retention appears consistent with the organization’s capital needs, asset quality and overall financial condition. Thus, under certain circumstances based upon our financial condition, our ability to declare and pay quarterly dividends may require consultation with the Federal Reserve and may be prohibited by applicable Federal Reserve guidelines.
Federal law prohibits us from borrowing from S&T Bank unless such loans are collateralized by specific obligations. Further, such loans are limited to 10 percent of S&T Bank’s capital stock and surplus.

NOTE 6. SECURITIES AVAILABLE-FOR-SALE -- continued


We do not believe any individual unrealized loss as of December 31, 20152018 represents an other than temporaryother-than-temporary impairment, or OTTI. As ofAt December 31, 2015, the2018, there were 65 debt securities and at December 31, 2017 there were 51 debt securities in an unrealized loss position. The unrealized losses on 26 debt securities were primarily attributable to changes in interest rates and not related to the credit quality of these securities.the issuers. All debt securities are determined to be investment grade and are paying principal and interest according to the contractual terms of the security. There were no unrealized losses on marketable equity securities at either December 31, 2015 or 2014. We do not intend to sell and it is more likely than not that we will not be required to sell any of the securities in an unrealized loss position before recovery of their amortized cost.

As of December 31, 2015,2018, our acquired loans from the Merger were $673.3$312.3 million including $293.2$180.4 million of CRE, $167.7$73.4 million of C&I, $69.2$6.6 million of commercial construction, $115.6$38.7 million of residential mortgage $27.5and $13.2 million of home equity, installment and other consumer construction. These acquired loans decreased from the original fair value on March, 2015acquired loans at December 31, 2017 of $788.7$386.6 million, including $331.6$208.5 million of CRE, $184.2$92.2 million of C&I, $92.4$11.1 million of commercial construction, $116.9$57.5 million of residential mortgage, $25.6$17.3 million of home equity, $36.1 million of installment and other consumer and $1.9 million of consumer construction.
As of December 31, 2015, we had $35.3 million of loans held for sale, which included $23.3 million related to the decision to sell our credit card portfolio and the remaining balance related to mortgages held for sale.
We attempt to limit our exposure to credit risk by diversifying our loan portfolio by segment, geography, collateral and industry and actively managing concentrations. When concentrations exist in certain segments, we mitigate this risk by monitoringreviewing the relevant economic indicators and internal risk rating trends and through stress testing of the loans in these segments. Total commercial loans represented 7679 percent of total portfolio loans at December 31, 20152018 and 7578 percent of total portfolio loans at December 31, 2014.2017. Within our commercial portfolio, the CRE and Commercial Construction portfolios combined comprised $2.6$3.2 billion or 6768 percent of total commercial loans and 5153 percent of total portfolio loans at December 31, 20152018 and 66comprised $3.1 billion or 68 percent of total commercial loans and 4953 percent of total portfolio loans at December 31, 2014. Of the $2.6 billion of CRE and Commercial Construction loans, $424.0 million were added as a result of the Merger.2017. Further segmentation of the CRE and Commercial Construction portfolios by industry and collateral type revealreveals no concentration in excess of seven14 percent of both total CRE and Commercial Construction loans at either December 31, 20152018 or December 31, 2014.2017.
Our market area includescustomers are primarily in Pennsylvania and the contiguous states of Ohio, West Virginia, New York, Maryland and Maryland.Delaware. The majority of our commercial and consumer loans are made to businesses and individuals in this market areathese states, resulting in a geographic concentration. We believe our knowledge and familiarity with customers and conditions locally outweighs this geographic concentration risk. The conditions of the local and regional economies are monitored closely through publicly available data as well asand information supplied by our customers. Management believes underwriting guidelines, active monitoring of economic conditions and ongoing review by credit administration mitigates the concentration risk present in the loan portfolio. Our CRE and Commercial Construction portfolios have out-of-market exposure of 5.85.4 percent of thetheir combined portfolioportfolios and 3.02.9 percent of total portfolio loans at December 31, 20152018 and 8.05.2 percent of thetheir combined portfolioportfolios and 3.92.8 percent of total portfolio loans at December 31, 2014.

TDRs are loans where we, for economic or legal reasons related to a borrower's financial difficulties, grant a concession to the borrower that we would not otherwise grant. We strive to identify borrowers in financial difficulty early and work with them to modify the terms before their loan reaches nonaccrual status. These modified terms generally include extensions of maturity dates at a stated interest rate lower than the current market rate for a new loan with similar risk characteristics, reductions in contractual interest rates or principal deferment. While unusual, there may be instances of principal forgiveness. These modifications are generally for longer term periods that would not be considered insignificant. Additionally, we classify loans where the debt obligation has been discharged through a Chapter 7 Bankruptcy and not reaffirmed as TDRs.
We individually evaluate all substandard commercial loans that have experienced a forbearance or change in terms agreement, as well as all substandard consumer and residential mortgage loans that entered into an agreement to modify their existing loan to determine if they should be designated as TDRs. All TDRs are considered to be impaired loans and will be reported as impaired loans for the remaining life of the loan, unless the restructuring agreement specifies an interest rate equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk and it is fully expected that the remaining principal and interest will be collected according to the restructured agreement. Further, all impaired loans are reported as nonaccrual loans unless the loan is a TDR that has met the requirements to be returned to accruing status. TDRs can be returned to accruing status if the ultimate collectability of all contractual amounts due, according to the restructured agreement, is not in doubt and there is a period of a minimum of six months of satisfactory payment performance by the borrower either immediately before or after the restructuring.

During 2015, we modified 39 loans that were not considered to be TDRs, including 11 C&I loansWe have six commitments for $7.8$11.6 million 14 Commercial Construction loans for $8.5 million, eight CRE loans for $6.1 million, four Home Equity loans for $0.4 million and two Residential Real Estate loans for $0.1 million. The modifications primarily represented instances where we were adequately compensated through additional collateral or a higher interest rate or there was an insignificant delay in payment. As of December 31, 2015, we have no commitments to lend additional funds on any TDRs.
TDRs at December 31, 2018. We had no TDRs that returned to accruing status during 2018. We returned eightone TDRs to accruing status during the twelve months ended December 31, 2015 totaling $0.4 million. We returned nine TDRs to accruing status during 2014 totaling $1.92017 for $2.0 million.

NPAs increased $24.8 million to $49.2 million during 2018 compared to $24.4 million for the year ended 2017. The increase is primarily related to three large commercial nonperforming, impaired loans of $23.6 million that experienced financial deterioration during the fourth quarter of 2018. Other real estate owned, or OREO, increased $2.6 million since December 31, 2017. The $2.5 million increase in NPAsOREO relates to two lots of land that were being held with the intention to build future branches. This is no longer the intention with these properties. This land lot was reclassified from other assets to OREO during 2015 was primarily due to subsequent deterioration on acquired loans since the acquisition date and a $4.7 million C&I loan. Included in the total NPAsfirst quarter of $35.7 million is approximately $16.3 million of loans from the Merger.2018.
We have granted loans to certain officers and directors of S&T as well as to certain affiliates of the officers and directors in the ordinary course of business. These loans were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with unrelated persons and did not involve more than normal risk of collectability.

NOTE 9.8. ALLOWANCE FOR LOAN LOSSES
We maintain an ALL at a level determined to be adequateappropriate to absorb estimated probable credit losses inherent inwithin the loan portfolio as of the balance sheet date. We develop and document a systematic ALL methodology based on the following portfolio segments: 1) CRE, 2) C&I, 3) Commercial Construction, 4) Consumer Real Estate and 5) Other Consumer.
The following are key risks within each portfolio segment:

CRE—Loans secured by commercial purpose real estate, including both owner occupiedowner-occupied properties and investment properties for various purposes such as hotels, strip malls and apartments. Operations of the individual projects as well asand global cash flows of the debtors are the primary sources of repayment for these loans. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the collateral type as well asand the business prospects of the lessee, if the project is not owner occupied.owner-occupied.

C&I—Loans made to operating companies or manufacturers for the purpose of production, operating capacity, accounts receivable, inventory or equipment financing. Cash flow from the operations of the company is the primary source of repayment for these loans. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the industry of the company. Collateral for these types of loans often dodoes not have sufficient value in a distressed or liquidation scenario to satisfy the outstanding debt.

Commercial Construction—Loans made to finance construction of buildings or other structures, as well as to finance the acquisition and development of raw land for various purposes. While the risk of these loans is generally confined to the construction period, if there are problems, the project may not be complete,completed, and as such, may not provide sufficient cash flow on its own to service the debt or have sufficient value in a liquidation to cover the outstanding principal. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the type of project and the experience and resources of the developer.

Consumer Real Estate—Loans secured by first and second liens such as home equity loans, home equity lines of credit and 1-4 family residences, including purchase money mortgages. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of

NOTE 9.8. ALLOWANCE FOR LOAN LOSSES -- continued


Consumer Real Estate—Loans secured by first and second liens such as home equity loans, home equity lines of credit and 1-4 family residential mortgages, including purchase money mortgages. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The state of the local housing market can also have a significant impact on this segment because low demand and/or declining home values can limit the ability of borrowers to sell a property and satisfy the debt.

Other Consumer—Loans made to individuals that may be secured by assets other than 1-4 family residences, as well as unsecured loans. This segment includes auto loans, unsecured loans and lines and credit cards. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The value of the collateral, if there is any, is less likely to be a source of repayment due to less certain collateral values.
We further assess risk within each portfolio segment by pooling loans with similar risk characteristics. For the commercial loan classes, the most important indicator of risk is the internally assigned risk rating, including pass, special mention and substandard. Consumer loans are pooled by type of collateral, lien position and loan to value, or LTV, ratio for Consumer Real Estate loans. Historical loss rates are applied to these loan pools to determine the reserve for loans collectively evaluated for impairment.
The ALL methodology for groups of loans collectively evaluated for impairment is comprised of both a quantitative and qualitative analysis. A key assumption in the quantitative component of the reserve is the LEP. The LEP is an estimate of the average amount of time from the point at which a loss is incurred on a loan to the point at which the loss is confirmed. Another key assumption is the look-back period, or LBP, which represents the historical data period utilized to calculate loss rates.
Management monitors various credit quality indicators for both the commercial and consumer loan portfolios, including delinquency, nonperforming status and changes in risk ratings on a monthly basis.

We continually monitor the commercial loan portfolio through an internal risk rating system. Loan risk ratings are assigned based upon the creditworthiness of the borrower and are reviewed on an ongoing basis according to our internal policies. Loans within the pass rating generally have a lower risk of loss than loans risk rated as special mention and substandard.

NOTE 8. ALLOWANCE FOR LOAN LOSSES -- continued

Our risk ratings are consistent with regulatory guidance and are as follows:
Pass—The loan is currently performing and is of high quality.
Special Mention—A special mention loan has potential weaknesses that warrant management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects or in the strength of our credit

NOTE 9. ALLOWANCE FOR LOAN LOSSES -- continued

position at some future date. Economic and market conditions, beyond the borrower’s control, may in the future necessitate this classification.
Substandard—A substandard loan is not adequately protected by the net worth and/or paying capacity of the borrower or by the collateral pledged, if any. Substandard loans have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. These loans are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected.
The following tables present the recorded investment in commercial loan classes by internally assigned risk ratings as of the dates presented:

Commercial substandard loans increased $110.5 million from December 31, 2017 mainly due to the receipt of updated financial information from the borrowers that resulted in the loans being downgraded.
We monitor the delinquent status of the consumer portfolio on a monthly basis. Loans are considered nonperforming when interest and principal are 90 days or more past due or management has determined that a material deterioration in the borrower’s financial condition exists. The risk of loss is generally highest for nonperforming loans.
The following tables present the recorded investment in consumer loan classes by performing and nonperforming status as of the dates presented:

NOTE 8. ALLOWANCE FOR LOAN LOSSES -- continued

We individually evaluate all substandard and nonaccrual commercial loans greater than $0.5 million for impairment. Loans are considered to be impaired when based upon current information and events it is probable that we will be unable to collect all principal and interest payments due according to the original contractual terms of the loan agreement. All TDRsA TDR will be reported as an impaired loan for the remaining life of the loan, unless the restructuring agreement specifies an interest rate equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk and it is expected that the remaining principal and interest will be fully collected according to the restructured agreement. For all TDRs, regardless of size, as well as alleach TDR or other impaired loans,loan, we conduct further analysis to determine the probable loss and assign a specific reserve to the loan if deemed appropriate.

Goodwill represents the excess of the purchase price over the fair value of net assets acquired. AdditionalDuring 2018, we sold a majority interest in our insurance business which reduced goodwill of $115.9 million was recorded during 2015, for our acquisition of Integrity. Refer to Note 2 Business Combinations for further details on the Integrity acquisition. There were no additions to goodwill in 2014.by $4.2 million.
Goodwill is reviewed for impairment annually or more frequently if it is determined that a triggering event has occurred. Based upon our qualitative assessment performed for our annual impairment analysis, we concluded that it is more likely than not that the fair value of the reporting units exceeds the carrying value. In general, the overall macroeconomic conditions and more specifically the economic conditions of the banking industry have continued to improve.been very good. Additionally, our overall performance has improvedbeen good and we did not identify any other facts and circumstances causing us to conclude that it is more likely than not that the fair value of the reporting units would be less than the carrying value.

NOTE 14.13. QUALIFIED AFFORDABLE HOUSING 
We invest in affordable housing projects primarily to satisfy our Community Reinvestment Act requirements. As a limited partner in these operating partnerships, we receive tax credits and tax deductions for losses incurred by the underlying properties. We use the cost method to account for these partnerships. Our total investment in qualified affordable housing projects, included in other assets in the Consolidated Balance Sheet, was $15.0$6.3 million at December 31, 20152018 and $18.6$9.0 million at December 31, 2014. We had no open commitments to fund current or future investments in qualified affordable housing projects at December 31, 2015 or December 31, 2014.2017. Amortization expense, included in other noninterest expense in the Consolidated Statements of Net Income, was $3.6$2.7 million, $3.0 million and $3.3 million for December 31, 20152018, 2017 and $4.1 million for both December 31, 2014 and 2013. Amortization expense was offset by2016. The tax credits of $4.0$3.1 million, $3.4 million and $3.7 million for December 31, 20152018, 2017 and $4.3 million for both December 31, 2014 and 2013,2016, are recognized as a reduction to our federal tax provision.

We evaluated our investments in affordable housing projects for impairment at December 31, 2018; the results indicated that the tax benefits associated with each investment exceeded the carrying values.

NOTE 16.15. SHORT-TERM BORROWINGS
Short-term borrowings are for terms under or equal to one year and wereare comprised of securities sold under REPOs and FHLB advances. All REPOs are overnight short-term investments and are not insured by the Federal Deposit Insurance Corporation, or FDIC. Securities pledged as collateral under these REPO financing arrangements cannot be sold or repledged by the secured party and, therefore, the REPOs are

therefore accounted for as a secured borrowing. Securitiesborrowings. Mortgage-backed securities with a totalamortized cost of $24.2 million and carrying value of $67.0$23.9 million at December 31, 20152018 and $35.6amortized cost of $57.5 million and carrying value of $56.8 million at December 31, 20142017 were pledged as collateral for these secured transactions. The pledged securities are held in safekeeping at the Federal Reserve. Due to the overnight short-term nature of REPOs, potential risk due to a decline in the value of the pledged collateral is low. Collateral pledging requirements with REPOs are monitored daily. FHLB advances are for various terms and are secured by a blanket lien on residential mortgages and other real estate secured loans.

We completed a private placement of the trust preferred securities to a financial institution during the first quarter of 2008. As a result, we own 100 percent of the common equity of STBA Capital Trust I. The trust was formed to issue mandatorily redeemable capital securities to third-party investors. The proceeds from the sale of the securities and the issuance of the common equity by STBA Capital Trust I were invested in junior subordinated debt securities issued by us. The third party investors are considered the primary beneficiaries;beneficiaries of STBA Capital Trust I; therefore, the trust qualifies as a VIE, but is not consolidated into our financial statements. STBA Capital Trust I pays dividends on the securities at the same rate as the interest paid by us on the junior subordinated debt held by STBA Capital Trust I.
We repaid $45.0 million of junior subordinated debt in June of 2013 because of its diminishing regulatory capital benefit and the future positive impact on net interest income. We replaced the funding primarily with FHLB short-term advances.
On March 4, 2015 we assumed a $13.5 million junior subordinated debt from the acquisition of Integrity. On March 5, 2015, we paid off $8.5 million and on June 18, 2015, we paid off the remaining $5.0 million.

The provision for income taxes differsTax Act includes significant changes to the U.S. corporate tax system including: a federal corporate rate reduction from 35 percent to 21 percent. The Tax Act also established new tax laws that became effective January 1, 2018. U.S. GAAP requires a company to record the amount computed by applyingeffects of a tax law change in the statutory federalperiod of enactment. As a result, in 2017 we re-measured our deferred tax assets and liabilities and recorded a provisional adjustment of $13.4 million. This re-measurement adjustment was recognized as an increase to our income tax rateexpense in the fourth quarter of 2017. The calculation over the income tax effects of the Tax Act was completed in the third quarter of 2018. We recognized a $3.0 million income tax benefit as a result of finalizing the calculation.
The statutory to income before income taxes. We ordinarily generate an annual effective tax rate thatreconciliation for the years ended December 31 is less than the statutory rate of 35 percent primarily due to benefits resulting from tax-exempt interest, excludable dividend income, tax-exempt income on BOLI and tax benefits associated with LIHTC from certain partnership investments.as follows:

We establish a valuation allowance when it is more likely than not that we will not be able to realize the benefit of the deferred tax assets. Except for Pennsylvania net operating losses, or NOLs, we have determined that a valuation allowance is unnecessary for the deferred tax assets because it is more likely than not that these assets will be realized through future reversals of existing temporary differences and through future taxable income. The valuation allowance is reviewed quarterly and adjusted based on management’s assessments of realizable deferred tax assets. Gross deferred tax assets were reduced by a valuation allowance of $2.7$4.6 million in 20152018 related to Pennsylvania income tax NOLs. The Pennsylvania NOL carryforwards total $26.7$45.8 million and will expire in the years 2020-2035.2020-2039.

The prior period data was not restated; as such, the change in unrealized gains on marketable securities is combined with the change in net unrealized gains on debt securities for the prior periods ended December 31, 2017 and 2016.

NOTE 21. EMPLOYEE BENEFITS 
We maintain a qualified defined benefit pension plan, or Plan, covering substantially all employees hired prior to January 1, 2008. The benefits are based on years of service and the employee’s compensation for the highest five consecutive years in the last ten years.years through March 31, 2016 when the Plan was frozen. Contributions are intended to provide for benefits attributed to employee service to date and for those benefits expected to be earned in the future.
Our qualified and nonqualified defined benefit plans were amended to freeze benefit accruals for all persons entitled to benefits under the plan in 2016. We will continue recording pension expense related to these plans, primarily representing interest costs on the accumulated benefit obligation and amortization of actuarial losses accumulated in the plan, as well as income from expected investment returns on pension assets. Since the plans have been frozen, no service costs are included in net periodic pension expense. The expected long-term rate of return on plan assets is 7.50 percent.
We made a $20.4 million contribution to our qualified defined benefit plan on September 7, 2018. The fair value of the plan was not re-measured for the impact of the contribution. The pension contribution was deducted on our 2017 Consolidated Federal Income Tax Return and we recognized a return to provision discrete tax benefit of $2.9 million due to the decrease in the federal statutory rate of 35 percent to 21 percent resulting from tax legislation enacted in December 2017.

The accumulated benefit obligation for the Plan was $101.6$95.2 million at December 31, 20152018 and $104.3$106.7 million at December 31, 2014.2017.
We consider many factors when setting the assumed rate of return on Plan assets. As a general guideline the assumed rate of return is equal to the weighted average of the expected returns for each asset category and is estimated based on historical returns as well as expected future returns. The weighted average discount rate is derived from corporate yield curves.
S&T Bank’s Retirement Plan Committee determines the investment policy for the Plan. In general, the targeted asset allocation is 5 percent to 15 percent equities and alternatives and 85 percent to 95 percent fixed income. In prior years the asset allocation was 50 percent to 70 percent equities and 30 percent to 50 percent fixed income. A strategic allocation within each asset class is employed based on the Plan’s duration, time horizon, risk tolerances, performance expectations, and asset class preferences. Investment managers have discretion to invest in any equity or fixed-income asset class, subject to the securities guidelines of the Plan’s Investment Policy Statement.
On December 19, 2017, S&T Bank, as Plan Sponsor, entered into an agreement with an insurance company to purchase a single premium annuity contract for 124 retired Plan participants and their beneficiaries. Of these participants, 30 are receiving a $2,000 death benefit only. The total premium of $1.5 million was paid out of the Plan's assets, and the effective date of the annuity payments was January 1, 2018. The annuity purchase resulted in a reduction in the associated pension liability.
At this time, S&T Bank is not required to make a cash contribution to the Plan in 2016. No contributions were made during 2015.2019.

We also have nonqualified supplemental executive pension plans, or SERPs, for certain key employees. The SERPs are unfunded. The projected benefit obligations related to the SERPs were $4.0$4.4 million and $3.5$5.3 million at December 31, 20152018 and 2014.2017. These amounts also represent the net amount recognized in the statement of financial position for the SERPs. Net periodic benefit costs for the SERPs were $0.6 million, $0.4 million and $0.4$0.5 million for each of the years ended December 31, 2015, 20142018, 2017 and 2013.2016. Additionally, $2.1$1.9 million, $2.7 million and $2.5 million before tax was reflected in accumulated other comprehensive income (loss) at both December 31, 20152018, 2017 and 2014,2016, in relation to the SERPs. The actuarial assumptions used for the SERPs are the same as those used for the Plan.
On January 25, 2016, the Board of Directors approved an amendment to freeze benefit accruals under the qualified and nonqualified defined benefit pension plans effective March 31, 2016. This change will result in no additional benefits being earned by participants in those plans based on service or pay after March 31, 2016. The Plan was previously closed to new participants effective December 31, 2007.
We maintain a Thrift Plan, a qualified defined contribution plan, in which substantially all employees are eligible to participate. We make matching contributions to the Thrift Plan up to 3.5 percent of participants’ eligible compensation and may make additional profit-sharing contributions as provided by the Thrift Plan. Expense related to these contributions amounted to $1.5$1.7 million in 2015, $1.32018, $1.8 million in 20142017 and $1.4$1.7 million in 2013.

NOTE 22. INCENTIVE AND RESTRICTED STOCK PLAN AND DIVIDEND REINVESTMENT PLAN
We adopted an Incentive Stock Plan in 2003 that provides for granting incentive stock options, nonstatutory stock options, restricted stock and appreciation rights. The 2003 Stock Plan had a maximum of 1,500,000 shares of our common stock that expired ten years from the date of board approval. No further awards will be granted under the 2003 Stock Plan and there are no awards outstanding under the plan as of December 31, 2015.
We adopted an Incentive Stock Plan in 2014 that provides for cash performance awards and for granting incentive stock options, nonstatutory stock options, restricted stock, restricted stock units and appreciation rights. The 2014 Incentive Plan has aA maximum of 750,000 shares of our common stock are available for awards granted under the 2014 Incentive Plan and the plan expires ten years from the date of board approval. With respect to stock compensation provisions, the 2014 Incentive Plan is similar to the 2003 Stock Plan, which the 2014 Stock Plan replaced.
Stock Options
As of December 31, 2015,2018, no nonstatutory stock options were outstanding under the 2014 Stock Plan. There are no outstanding shares for nonstatutory stock option awards remaining under the 2003 Stock Plan orPlan.
Restricted Stock
We periodically issue restricted stock to employees and directors, pursuant to our 2014 Stock Plan. As of December 31, 2018, 442,567 restricted shares have been granted under the 2014 Stock Plan. Nonstatutory
During 2018, 2017, and 2016, we granted 9,264, 12,728 and 15,613 restricted shares of common stock options granted in 2005 are fully vested and had a ten year life. These stock options were fully expensed in 2010.
The fair value of nonstatutory stock option awardsto outside directors under the 20032014 Stock Plan were estimatedPlan. The grants are part of the compensation arrangement approved by the Compensation and Benefits Committee whereby the directors receive compensation in the form of both cash and restricted shares of common stock. These shares fully vest one year after the date of grant. The closing price of our stock is used to determine the fair value on the date of grant usinggrant.
During 2018, 2017, and 2016, we granted 66,733, 77,387 and 95,030 restricted shares of common stock to senior management under our Long Term Incentive Plan, or LTIP, within the Black-Scholes valuation model, which2014 Stock Plan. The restricted shares granted under the LTIP consist of both time and performance-based awards. The awards were granted in accordance with performance levels set by the Compensation and Benefits Committee. Vesting for the time-based awards is dependent upon certain assumptions. We use50 percent after two years and the simplified method in developing the estimated life of the option, whereby the expected life is presumed to be the midpoint between the vesting date andremaining 50 percent at the end of the contractual term. There have been no nonstatutorythird year. The performance-based awards vest at the end of the three-year period. During the vesting period, if the recipient leaves S&T before the end of the vesting period, shares will be forfeited except in the case of retirement, disability or death where accelerated vesting provisions are defined within the awards agreement.

The aggregate intrinsic value of options outstanding and exercisable was zero as of December 31, 2014 and 2013. The aggregate intrinsic value represents the total pretax intrinsic value (the difference between our closing stock price on the last trading day of the fourth quarter and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised the options on December 31, 2014 and 2013.
Restricted Stock
We periodically issue restricted stock to employees and directors, pursuant to our Stock Plans. As of December 31, 2015, 259,673 restricted shares have been granted under the 2003 Stock Plan and 168,296 restricted shares have been granted under the 2014 Stock Plan.
During 2015, 2014, and 2013, we granted 16,142, 13,824 and 18,942 restricted shares of common stock, to outside directors. The 2015 and 2014 grants were issued under the 2014 Stock Plan and the 2013 grants were issued under the 2003 Stock Plan. The grants are part of the compensation arrangement approved by the Compensation and Benefits Committee whereby the directors receive compensation in both the form of cash and restricted shares of common stock. These shares fully vest one year after the date of grant. The fair value is determined by the closing price of the stock on the date of grant.
During 2015, 2014, and 2013, we granted 71,699, 66,631 and 3,247 restricted shares of common stock to senior management under our Long Term Incentive Plan, or LTIP. The restricted shares granted under the LTIP for 2015 and 2014 of 71,699 and 66,631 shares, consisted of both time and performance-based awards. The 2015 and 2014 grants were issued under the 2014 Stock Plan and the 2013 grants were issued under the 2003 Stock Plan. The awards to senior management were granted in accordance with performance levels set by the Compensation and Benefits Committee. Vesting for the time-based awards is 50 percent after two years and the remaining 50 percent at the end of the third year. The performance-based awards vest at the end of the three-year period. During the vesting period, the recipient receives dividends and has the right to vote the unvested shares granted, except for the 2015 and 2014 LTIP performance-based awards. If the recipient leaves S&T before the end of the vesting period, shares will be forfeited except in the case of retirement, disability or death where accelerated vesting provisions are defined within the awards agreement. During 2013, additional restricted shares were granted on two occasions with different vesting periods. The restricted stock grants for 2013 of 3,247 shares vested fully on the second anniversary of the grant date.
Compensation expense for time-based restricted stock is recognized ratably over the period of service, generally the entire vesting period, based on fair value on the date of grant. Compensation expense for performance-based restricted stock is recognized ratably over the remaining vesting period once the likelihood of meeting the performance measure is probable. The average of the high and low prices of the stock on the grant date is used for senior management. During 2015, 2014 and 2013, we recognized compensation expense of $1.7 million, $0.9 million and $0.6 million and realized a tax benefit of $0.6 million, $0.3 million and $0.2 million related to restricted stock grants.

NOTE 24. REGULATORY MATTERS
We are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet the minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our consolidated financial statements.Consolidated Financial Statements. Under capital guidelines and the regulatory framework for prompt corrective action, we must meet specific capital guidelines that involve quantitative measures of our assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. Our capital amounts and classification are also subject to qualitative judgments by the regulators about risk weightings and other factors.
The most recent notifications from the Federal Reserve and the FDIC categorized S&T and S&T Bank as well capitalized under the regulatory framework for corrective action. There have been no conditions or events that we believe have changed S&T&T's or S&T Bank’s status during 20152018 and 2014.2017.
TierCommon equity tier 1 capital consists principally of shareholders’ equity, including preferred stock; excluding items recorded inincludes common stock and related surplus plus retained earnings, less goodwill and intangible assets subject to a limitation and certain deferred tax assets subject to a limitation. In addition, we made a one-time permanent election to exclude accumulated other comprehensive income (loss), less goodwill and other intangibles.from capital. For regulatory purposes, trust preferred securities totaling $20.0 million, issued by an unconsolidated trust subsidiary of S&T underlying junior subordinated debt, are included in Tier 1 capital for S&T. Total capital consists of Tier 1 capital plus junior subordinated debt and the ALL subject to limitation. We currently have $25.0 million in junior subordinated debt which is included in Tier 2 capital for S&T in accordance with current regulatory reporting requirements.
Quantitative measures established by regulation to ensure capital adequacy require us to maintain minimum amounts and ratios of Total, Tier 1 and Common Equity Tier 1 capital to risk-weighted assets and Tier 1 capital to average assets. As of December 31, 20152018 and 2014,2017, we met all capital adequacy requirements to which we are subject.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
