NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Basis of presentation
The accounting and reporting policies of the Company are in accordance with GAAP and conform to practices within the financial services industry. The accounts of the Company and its consolidated subsidiaries are included in the Consolidated Financial Statements.
Recent accounting pronouncements
Convertible Debt and Derivatives and Hedging
In August 2020, the FASB issued guidance within ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). The amendments in this update affect entities that issue convertible instruments and/or contracts indexed to and potentially settled in an entity’s own equity. The new ASU simplifies the convertible accounting framework through elimination of the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, the new guidance modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted EPS computation. The amendments to Subtopics 470 and 815 are effective for interim and annual reporting periods beginning after December 15, 2021 and are not expected to have a material impact on the Company’s Consolidated Financial Statements.
Income Taxes
In December 2019, the FASB issued guidance within ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in ASU 2019-12 are intended to reduce the cost and complexity of applying ASC 740. The amendments that are applicable to the Company address: 1) franchise and other taxes partially based on income; 2) step-up in basis of goodwill in a business combination; 3) allocation of tax expense in separate entity financial statements; and 4) interim recognition of enactment of tax laws or rate changes. The amendments to Topic 740 are effective for interim and annual reporting periods beginning after December 15, 2020 and are not expected to have a material impact on the Company’s Consolidated Financial Statements.
Recently adopted accounting guidance
Measurement of Credit Losses on Financial Instruments
In June 2016, the FASB issued guidance within ASU 2016-13, Measurement of Credit Losses on Financial Instruments. The new standard significantly changes the impairment model for most financial assets that are measured at amortized cost, including off-balance sheet credit exposures, from an incurred loss model to an expected loss model. The amendments in ASU 2016-13 to Topic 326, Financial Instruments - Credit Losses, require that an organization measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The ASU also requires enhanced disclosures, including qualitative and quantitative disclosures that provide additional information about the amounts recorded in the financial statements. Additionally, the ASU amends the accounting for credit losses on AFS debt securities and purchased financial assets with credit deterioration.
The Company adopted the amendments within ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. The Company's financial results for reporting periods
11

Table of Contents
beginning after January 1, 2020 are presented in accordance with ASC 326, while prior-period amounts continue to be reported in accordance with legacy GAAP. The Company recorded a cumulative effect adjustment to retained earnings, which resulted in a total decrease to retained earnings of $24.9 million as of January 1, 2020. This adjustment was due primarily to expected total losses under the new model in the Company's loan portfolio and, to a lesser extent, its off-balance sheet credit exposures.
The Company applied the prospective transition approach for loans purchased with credit deterioration that were previously classified as purchased credit impaired and previously accounted for under ASC 310-30. In accordance with the new standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. As of January 1, 2020, the amortized cost basis of the PCD loans was adjusted to reflect an allowance for credit losses of $3.3 million. The remaining noncredit discount (based on the adjusted amortized cost basis) related to PCD loans of $1.1 million will be accreted into interest income at the loan's effective interest rate as of January 1, 2020. The Company has elected not to maintain its pools of loans accounted for under ASC 310-30.
The Company applied the prospective transition approach for debt securities for which other-than-temporary impairment had been recognized prior to January 1, 2020. As a result, the amortized cost basis remains the same before and after the effective date. The effective interest rate on these debt securities was not changed. Recoveries of amounts previously written off relating to improvements in cash flows after January 1, 2020 will be recorded in earnings when received.
The following table summarizes the estimated allowance for credit losses related to financial assets and off-balance sheet credit exposures and the corresponding impacts on the deferred tax asset and retained earnings upon adoption of ASC 326:

Management has elected to take advantage of the capital relief option that delays the estimated impact of the adoption of ASC 326 on regulatory capital by up to two years, with a three-year transition period to phase out the cumulative benefit to regulatory capital provided during the two-year delay.
In April 2019, the FASB issued guidance within ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. The amendments in ASU 2019-04 clarify or correct the guidance in these Topics. With respect to Topic 326, ASU 2019-04 addresses a number of issues as it relates to the CECL standard including consideration of accrued interest, recoveries, variable-rate financial instruments, prepayments, and extension and renewal options, among other things, in the measurement of expected credit losses. The amendments to Topic 326 were adopted concurrently with ASU 2016-13 and did not have a significant impact on the Company’s Consolidated Financial Statements. With respect to Topic 815, Derivatives and Hedging, ASU 2019-04 clarifies issues related to partial-term hedges, hedged debt securities, and transitioning from a quantitative method of assessing hedge effectiveness to a more simplified method. The Company does not have partial-term hedges or any hedged debt securities and the transition issues discussed in the ASU 2019-04 are not applicable to the Company. Accordingly, the amendments to Topic 815 did not have an impact on the Company's Consolidated Financial Statements. With respect to Topic 825, Financial Instruments, on recognizing and measuring financial instruments, ASU 2019-04 addresses: 1) the scope of the guidance; 2) the requirement for remeasurement under ASC 820 when using the measurement alternative for equity securities without readily determinable fair values; 3) certain disclosure requirements; and 4) which equity securities have to be remeasured at historical exchange rates. The amendments to Topic 825 were effective January 1, 2020 and did not have a material impact on the Company’s Consolidated Financial Statements.
In May 2019, the FASB issued guidance within ASU 2019-05, Financial Instruments - Credit Losses, to provide entities with an option to irrevocably elect the fair value option for eligible financial assets measured at amortized cost. The election is to be applied on an instrument-by-instrument basis upon adoption of Topic 326 and is not available for either AFS or HTM debt securities. The amendments in ASU 2019-05 should be applied on a modified-retrospective basis through a cumulative-effect

In November 2019, the FASB issued guidance within ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments—Credit Losses. The amendments in ASU 2019-11 clarify or address specific issues about certain aspects of the amendments in ASU 2016-13. These issues include measurement and reporting requirements related to: 1) the allowance for credit losses for purchased assets with credit deterioration; 2) prepayment assumptions on existing troubled debt restructurings; 3) extension of disclosure relief for accrued interest receivable balances; and 4) expected credit losses on collateralized financial assets. The adoption of ASU 2019-11 is concurrent with ASU 2016-13 and, adoption of these amendments on January 1, 2020, did not have a significant impact on the Company's Consolidated Financial Statements.
Fair Value Measurements
In August 2018, the FASB issued guidance within ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The amendments within ASU 2018-13 remove, modify, and supplement the disclosure requirements for fair value measurements. Disclosure requirements that were removed include: 1) the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; 2) the policy for timing of transfers between levels; and 3) the valuation processes for Level 3 fair value measurements. The amendments clarify that the measurement uncertainty disclosure is intended to communicate information about the uncertainty in measurement as of the reporting date. Additional disclosure requirements include: 1) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and 2) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. With the exception of the above additional disclosure requirements, which will be applied prospectively, all other amendments should be applied retrospectively to all periods presented upon their effective date. The amendments in this ASU did not have a significant impact on the Company's Consolidated Financial Statements.
Internal-Use Software
In August 2018, the FASB issued guidance within ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40). The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments in this Update require an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The amendments in this Update also require that the capitalized implementation costs of a hosting arrangement that is a service contract be expensed over the term of the hosting arrangement. Presentation requirements include: 1) expense related to the capitalized implementation costs should be presented in the same line item in the statement of income as the fees associated with the hosting element (service) of the arrangement; 2) payments for capitalized implementation costs in the statement of cash flows should be classified in the same manner as payments made for fees associated with the hosting element; and 3) capitalized implementation costs in the statement of financial position should be presented in the same line item that a prepayment for the fees of the associated hosting arrangement would be presented. The adoption of this guidance did not have a significant impact on the Company's Consolidated Financial Statements.
Reference Rate Reform
In March 2020, the FASB issued guidance within ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, in response to the scheduled discontinuation of LIBOR on December 31, 2021. The amendments in this Update provide optional guidance designed to provide relief from the accounting analysis and impacts that may otherwise be required for modifications to agreements (e.g., loans, debt securities, derivatives, borrowings) necessitated by reference rate reform.
The following optional expedients for applying the requirements of certain Topics or Industry Subtopics in the Codification are permitted for contracts that are modified because of reference rate reform and that meet certain scope guidance: 1) modifications of contracts within the scope of Topics 310, Receivables, and 470, Debt, should be accounted for by prospectively adjusting the effective interest rate; 2) modifications of contracts within the scope of Topic 842, Leases, should be accounted for as a continuation of the existing contracts with no reassessments of the lease classification and the discount rate or remeasurements of lease payments that otherwise would be required under this Topic for modifications not accounted for as separate contracts; 3) modifications of contracts do not require an entity to reassess its original conclusion about whether that contract contains an embedded derivative that is clearly and closely related to the economic characteristics and risks of the host contract under Subtopic 815-15, Derivatives and Hedging- Embedded Derivatives; and 4) for other Topics or Industry Subtopics in the Codification, the amendments in this Update also include a general principle that permits an entity to consider

contract modifications due to reference rate reform to be an event that does not require contract remeasurement at the modification date or reassessment of a previous accounting determination. An entity may make a one-time election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that are classified as held to maturity before January 1, 2020.
The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022.
Use of estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management's estimates and judgments are ongoing and are based on experience, current and expected future conditions, third-party evaluations and various other assumptions that management believes are reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities, as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. Actual results may differ from those estimates and assumptions used in the Consolidated Financial Statements and related notes. Material estimates that are particularly susceptible to significant changes in the near term, particularly to the extent that economic conditions worsen or persist longer than expected in an adverse state, relate toto: the determination of the allowance for credit losses; estimated cash flows related to PCI loans; fair value determinations related to acquisitions and certain assets and liabilities carried at fair value; and accounting for income taxes.
Principles of consolidation
As of September 30, 2017,2020, WAL has tenthe following significant wholly-owned subsidiaries: WAB LVSP, and eight8 unconsolidated subsidiaries used as business trusts in connection with the issuance of trust-preferred securities.
The Bank has the following significant wholly-owned subsidiaries: WABT, which holds certain investment securities, municipal and nonprofit loans, and leases; WA PWI, LLC, which holds interests in certain limited partnerships invested primarily in low income housing tax credits and small business investment corporations; Helios Prime, which holds interests in certain limited partnerships invested in renewable energy projects; and BW Real Estate, Inc., which operates as a real estate investment trust and holds certain of WAB's real estate loans and related securities.

Reclassifications
Certain amounts reported in prior periods may have been reclassified in the Consolidated Financial Statements to conform to the current presentation. The reclassifications have no effect on net income or stockholders’ equity as previously reported.

Interim financial information
The accompanying Unaudited Consolidated Financial Statements as of and for the three and nine months ended September 30, 20172020 and 20162019 have been prepared in condensed format and, therefore, do not include all of the information and footnotes required by GAAP for complete financial statements. These statements have been prepared on a basis that is substantially consistent with the accounting principles applied to the Company's audited Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016.

2019.
The information furnished in these interim statements reflects all adjustments whichthat are, in the opinion of management, necessary for a fair statement of the results for each respective period presented. Such adjustments are of a normal, recurring nature. The results of operations in the interim statements are not necessarily indicative of the results that may be expected for any other quarter or for the full year. The interim financial information should be read in conjunction with the Company's audited Consolidated Financial Statements.
Business combinations
Business combinations are accounted for under the acquisition method of accounting in accordance with ASC 805, Business Combinations. Under the acquisition method, the acquiring entity in a business combination recognizes all of the acquired assets and assumed liabilities at their estimated fair values as of the date of acquisition. Any excess of the purchase price over the fair value of net assets and other identifiable intangible assets acquired is recorded as goodwill. To the extent the fair value of net assets acquired, including identified intangible assets, exceeds the purchase price, a bargain purchase gain is recognized. Changes to estimated fair values from a business combination are recognized as an adjustment to goodwill during the measurement period and are recognized in the proper reporting period in which the adjustment amounts are determined. Results of operations of an acquired business are included in the Consolidated Income Statement from the date of acquisition. Acquisition-related costs, including conversion and restructuring charges, are expensed as incurred.
Investment securities
Investment securities include debt and equity securities. Debt securities may be classified as HTM, AFS, or measured at fair value.trading. The appropriate classification is initially decided at the time of purchase. Securities classified as HTM are those debt securities that the Company has both the intent and ability to hold to maturity regardless of changes in market conditions, liquidity needs, or general economic conditions. These securities are carried at amortized cost. The sale of aan HTM security within three months of its maturity date or after the majority of the principal outstanding has been collected is considered a maturity for purposes of classification and disclosure.
Securities classified as AFS or trading securities measured at fair value are reported as an asset in the Consolidated Balance Sheet at their estimated fair value. As the fair value of AFS securities changes, the changes are reported net of income tax as an element of OCI, except for other-than-temporarily-impaired securities. When AFS securities are sold, the unrealized gain or loss is reclassified from OCI to non-interest income. The changes in the fair values of trading securities are reported in non-interest income. Securities classified as AFS are both equity and debt securities that the Company intends to hold for an indefinite period of time, but not necessarily to

maturity. Any decision to sell a security classified as AFS would be based on various factors, including significant movements in interest rates, changes in the maturity mix of the Company’s assets and liabilities, liquidity needs, decline in credit quality, and regulatory capital considerations.
HTM securities are carried at amortized cost. AFS securities are carried at their estimated fair value, with unrealized holding gains and losses reported in other comprehensive income, net of tax. When AFS debt securities are sold, the unrealized gains or losses are reclassified from OCI to non-interest income. Trading securities are carried at their estimated fair value, with changes in fair value reported in earnings as part of non-interest income.
Equity securities are carried at their estimated fair value, with changes in fair value reported in earnings as part of non-interest income.
Interest income is recognized based on the coupon rate and increased by accretion of discounts earned or decreased byincludes the amortization of purchase premiums paidand the accretion of purchase discounts. Premiums and discounts on investment securities are generally amortized or accreted over the contractual life of the security adjusted for prepayment estimates, using the interest method. For the Company's mortgage-backed securities, amortization or accretion of premiums or discounts are adjusted for anticipated prepayments. Gains and losses on the sale of investment securities are recorded on the trade date and determined using the specific identification method.
In estimating whether thereA debt security is placed on nonaccrual status at the time its principal or interest payments become 90 days past due. Interest accrued but not received for a security placed on nonaccrual is reversed against interest income.
Allowance for credit losses on investment securities
On January 1, 2020, the Company adopted the amendments within ASU 2016-13, which replaces the legacy US GAAP OTTI model with a credit loss model. For discussion of the former OTTI methodology, refer to the Company's Annual Report on Form 10-K for the year ended December 31, 2019. The credit loss model under ASC 326-20, applicable to HTM debt securities, requires recognition of lifetime expected credit losses through an allowance account at the time the security is purchased. The Company measures expected credit losses on its HTM debt securities on a collective basis by major security type. The Company's HTM securities portfolio consists of low income housing tax-exempt bonds, which share similar risk characteristics with the Company's CRE, non-owner occupied or construction and land loan pools, given the similarity in underlying assets or collateral. Accordingly, expected credit losses on HTM securities are anyestimated using the same models and approaches as these loan pools, which utilize risk parameters (probability of default, loss given default, and exposure at default) in the measurement of expected credit losses. The historical data used to estimate probability of default and severity of loss in the event of default is derived or obtained from internal and external sources and adjusted for the expected effects of reasonable and supportable forecasts over the expected lives of the securities on those historical losses. Accrued interest receivable on the HTM securities, which is included in other assets on the Consolidated Balance Sheet, is excluded from the estimate of expected credit losses.
The credit loss model under ASC 326-30, applicable to AFS debt securities, requires recognition of credit losses through an allowance account, but retains the concept from the OTTI model that credit losses management considersare recognized once securities become impaired. For AFS debt securities, a decline in fair value due to credit loss results in recognition of an allowance for credit losses. Impairment may result from credit deterioration of the 1) lengthissuer or collateral underlying the security. The assessment of time anddetermining if a decline in fair value resulted from a credit loss is performed at the individual security level. Among other factors, the Company considers: 1) the extent to which the fair value has beenis less than the amortized cost;cost basis; 2) the financial condition and near term prospects of the issuer, including consideration of relevant financial metrics or ratios of the issuer; 3) impactany adverse conditions related to an industry or geographic area of an issuer; 4) any changes in market interest rates; and 4) intent and abilityto the rating of the security by a rating agency; and 5) any past due principal or interest payments from the issuer. If an assessment of the above factors indicates that a credit loss exists, the Company records an allowance for credit losses for the excess of the amortized cost basis over the present value of cash flows expected to retain its investment for a period of time sufficientbe collected, limited to allow for any anticipated recovery inthe amount that the security's fair value and whether it is not more likelyless than not the Company would be required to sell the security.
Declines in the fair value of individual AFS debt securities that are deemed to be other-than-temporary are reflected in earnings when identified. The fair value of the debt security then becomes the new cost basis. For individual debt securities where the Company does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis,basis. Subsequent changes in the other-than-temporary decline in fair value of the debt security related to 1)allowance for credit losses are recorded as a provision for (or reversal of) credit loss is recognized in earnings; and 2) interest rate, market, or other factors is recognized in other comprehensive income or loss.

For individual debt securities where the Company either intends to sell the security or more likely than not will not recover all of its amortized cost, the OTTI is recognized in earnings equal to the entire difference between the security's cost basis and its fair value at the balance sheet date. For individual debt securities for which a credit loss has been recognized in earnings, interestexpense. Interest accruals and amortization and accretion of premiums and discounts are suspended when the credit loss is recognized. Interestrecognized in earnings. Any interest received after accruals havethe security has been suspendedplaced on nonaccrual status is recognized on a cash basis. Accrued interest receivable on AFS securities, which is included in other assets on the Consolidated Balance Sheet, is excluded from the estimate of expected credit losses.
For each AFS security in an unrealized loss position, the Company also considers: 1) its intent to retain the security until anticipated recovery of the security's fair value; and 2) whether it is more-likely-than not that the Company would be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the debt security is written down to its fair value and the write-down is charged against the allowance for credit losses with any incremental impairment recorded in earnings.

Writeoffs are made through reversal of the allowance for credit losses and direct writeoff of the amortized cost basis of the AFS security. The Company considers the following events to be indicators that a writeoff should be taken: 1) bankruptcy of the issuer; 2) significant adverse event(s) affecting the issuer in which it is improbable for the issuer to make its remaining payments on the security; and 3) significant loss of value of the underlying collateral behind a security. Recoveries on debt securities, if any, are recorded in the period received.
Restricted stock
WAB is a member of the Federal Reserve System and, as part of its membership, is required to maintain stock in the FRB in a specified ratio to its capital. In addition, WAB is a member of the FHLB system and, accordingly, maintains an investment in capital stock of the FHLB based on the borrowing capacity used. The Bank also maintains an investment in its primary correspondent bank. All of theseThese investments are considered equity securities with no actively traded market. Therefore, the shares are considered restricted investment securities. These investments are carried at cost, which is equal to the value at which they may be redeemed. The dividend income received from the stock is reported in interest income. The Company conducts a periodic review and evaluation of its restricted stock to determine if any impairment exists. No impairment has been recorded to date.
Loans held for sale
Loans held for sale consist of SBA loans that the Company originates (or acquires) and intends to sell. These loans are carried at the lower of aggregate cost or fair value. Fair value is determined based on quoted fair market values or, when not available, market data for similar assets, expecteddiscounted cash flows andor appraisals of underlying collateral or the credit quality of the borrower. Gains and losses on the sale of loans are recognized pursuant to ASC 860, Transfers and Servicing. Interest income of these loans is accrued daily and loan origination fees and costs are deferred and included in the cost basis of the loan. The Company issues various representations and warranties associated with these loan sales. The Company has not experienced any losses as a result of these representations and warranties.
Loans held for investment
The Company generally holds loans for investment andLoans that management has the intent and ability to hold loansfor the foreseeable future or until their maturity. Therefore, theymaturity or payoff are reported at book value. Net loans are stated atamortized cost. Amortized cost is the amount of unpaid principal, adjusted for unamortized net deferred fees and costs, purchase accounting fair value adjustments,premiums and an allowance for credit losses.discounts, and writeoffs. In addition, the book valueamortized cost of loans that are subject to a fair value hedge isare adjusted for changes in value attributable to the effective portion of the hedged benchmark interest rate risk.
The Company may also purchase loans or acquire loans through a business combination. These acquiredAt the purchase or acquisition date, loans are recorded at estimated fair value on the date of purchase, which is comprised of unpaid principal adjusted for estimated credit losses and interest rate fair value adjustments. Loans are evaluated individually at the acquisition date to determine if there has been more than insignificant credit deterioration since origination. Such loans may then be aggregated and accounted forLoans that have experienced more than insignificant credit deterioration since origination are referred to as PCD loans. In its evaluation of whether a pool of loans based on common characteristics. Whenloan has experienced more than insignificant deterioration in credit quality since origination, the Company acquires such loans, the yield that may be accreted (accretable yield) is limited to the excess of the Company’s estimate of undiscounted cash flows expected to be collected over the Company’s initial investment in the loan. The excess of contractual cash flows over the cash flows expected to be collected may not be recognized as an adjustment to yield, loss, or a valuation allowance. Subsequent increases in cash flows expected to be collected generally are recognized prospectively through adjustment of the loan’s yield over the remaining life. Subsequent decreases to cash flows expected to be collected are recognized as impairment.takes into consideration loan grades, loan-to-values greater than policy limits, past due and nonaccrual status, and TDR loans. The Company may not carry overalso consider external credit rating agency ratings for borrowers and for non-commercial loans, FICO score or create a valuation allowance inband, probability of default levels, number of times past due, and standard deviations corresponding to FICO score or band. The initial estimate of credit losses on PCD loans is added to the purchase price on the acquisition date to establish the initial accountingamortized cost basis of the loan; accordingly, the initial recognition of expected credit losses has no impact on net income. When the initial measurement of expected credit losses on PCD loans are calculated on a pooled loan basis, the expected credit losses are allocated to each loan within the pool. Any difference between the initial amortized cost basis and the unpaid principal balance of the loan represents a noncredit discount or premium, which is accreted (or amortized) into interest income over the life of the loan. Subsequent changes to the allowance for credit losses on PCD loans acquired under these circumstances.are recorded through the provision for credit losses. For purchased loans that are not deemed impaired atto have experienced more than insignificant credit deterioration since origination, any discounts or premiums included in the acquisition date, fair value adjustments attributable to both credit and interest ratespurchase price are accreted (or amortized) over the contractual life of the individual loan. For additional information, see "Note 3. Loans, Leases and Allowance for Credit Losses" of these Notes to Unaudited Consolidated Financial Statements.
LoanIn applying the effective yield method to loans, the Company generally applies the contractual method whereby loan fees collected for the origination of loans less direct loan origination costs (net of deferred loan fees), as well as premiums and discounts and certain purchase accounting adjustments, are amortized over the contractual life of the loan through interest income. If thea loan has scheduled payments, the amortization of the net deferred loan fee is calculated using the interest method over the contractual life of the loan. If thea loan does not have scheduled payments, such as a line of credit, the net deferred loan fee is recognized as interest income on a straight-line basis over the contractual life of the loan commitment. Commitment fees based on a percentage of a customer’s unused line of credit and fees related to standby letters of credit are recognized over the commitment period. When loans are repaid, any remaining unamortized balances of premiums, discounts, or net deferred fees are recognized as interest income.
Non-accrual loans:Conversely, with respect to loans originated under the PPP, the Company incorporates projected prepayments in calculating effective yield. As a result, net deferred fees are accreted into interest income faster than would be the case when applying the contractual method based upon the timing and amount of estimated forgiven loan balances. The Company expects that a
16

majority of PPP loans will qualify for forgiveness under the SBA program, based on requested loan amounts largely representing qualifying expenses at the time of application.
Nonaccrual loans
When a borrower discontinues making payments as contractually required by the note, the Company must determine whether it is appropriate to continue to accrue interest. The Company ceases accruing interest income when the loan has become delinquent by more than 90 days or when management determines that the full repayment of principal and

collection of interest according to contractual terms is no longer likely. Past due status is based on the contractual terms of the loan. The Company may decide to continue to accrue interest on certain loans more than 90 days delinquent if the loans are well secured by collateral and in the process of collection.
For all loan types, when a loan is placed on non-accrualnonaccrual status, all interest accrued but uncollected is reversed against interest income in the period in which the status is changed, and the Company makes a loan-level decision to apply either the cash basis or cost recovery method. The Company recognizesmay recognize income on a cash basis when a payment is received and only for those non-accrualnonaccrual loans for which the collection of the remaining principal balance is not in doubt. Under the cost recovery method, subsequent payments received from the customer are applied to principal and generally no further interest income is recognized until the principal has been paid in full or until circumstances have changed such that payments are again consistently received as contractually required.
Impaired loans: A loan is identified as impaired Loans are returned to accrual status when it is no longer probable that interest and principal will be collected according to the contractual termsall of the original loan agreement. Generally, impaired loans are classified as non-accrual. However, in certain instances, impaired loans may continue on an accrual basis, if full repayment of all principal and interest is expectedamounts contractually due are brought current and the loan is both well secured and in the process of collection. Impaired loansfuture payments are measured for reserve requirements in accordance with ASC 310, Receivables, based on the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of the collateral less applicable disposition costs if the loan is collateral dependent. The amount of an impairment reserve, if any, and any subsequent changes are recorded as a provision for credit losses. Losses are recorded as a charge-off when losses are confirmed. In addition to management's internal loan review process, regulators may from time to time direct the Company to modify loan grades, loan impairment calculations, or loan impairment methodology.reasonably assured.
Troubled Debt Restructured Loans:
A TDR loan is a loan on which the Company, for reasons related to a borrower’s financial difficulties, grants a concession to the borrower that the Company would not otherwise consider. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. The evaluation is performed under the Company's internal underwriting policy. The loan terms that have beenmay be modified or restructured due to a borrower’s financial situation include, but are not limited to, a reduction in the stated interest rate, an extension of the maturity or renewal of the loan at an interest rate below current market, a reduction in the face amount of the debt, a reduction in the accrued interest, or deferral of interest payments. A TDR loan is also considered impaired. A TDR loan may be returned to accrual status when the loan is brought current, has performed in accordance with the contractual restructured terms for a reasonable period of time (generally six months), and the ultimate collectability of the total contractual restructured principal and interest is no longer in doubt. However, such loans continue to be considered impaired. Consistent with regulatory guidance, a TDR loan that is subsequently modified in another restructuring agreement but has shown sustained performance and classification as a TDR, will be removed from TDR status provided that the modified terms were market-based at the time of modification.
The CARES Act, signed into law on March 27, 2020, permits financial institutions to suspend requirements under GAAP for loan modifications to borrowers affected by COVID-19 that would otherwise be characterized as TDRs and suspend any determination related thereto if (i) the loan modification is made between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the end of the coronavirus emergency declaration and (ii) the applicable loan was not more than 30 days past due as of December 31, 2019. In addition, federal bank regulatory authorities have issued guidance to encourage financial institutions to make loan modifications for borrowers affected by COVID-19 and have assured financial institutions that they will neither receive supervisory criticism for such prudent loan modifications, nor be required by examiners to automatically categorize COVID-19-related loan modifications as TDRs. The Company is applying this guidance to qualifying loan modifications.
Credit quality indicators
Loans are regularly reviewed to assess credit quality indicators and to determine appropriate loan classification and grading in accordance with applicable bank regulations. The Company’s risk rating methodology assigns risk ratings ranging from 1 to 9, where a higher rating represents higher risk. The Company differentiates its loan segments based on shared risk characteristics for which expected credit loss is measured on a pool basis.
The nine risk rating categories can be generally described by the following groupings for loans:
"Pass" (grades 1 through 5): TheCompany has five pass risk ratings, which represent a level of credit quality that ranges from no well-defined deficiency or weakness to some noted weakness; however, the risk of default on any loan classified as pass is expected to be remote. The five pass risk ratings are described below:
Minimal risk. These consist of loans that are fully secured either with cash held in a deposit account at the Bank or by readily marketable securities with an acceptable margin based on the type of security pledged.
17

Table of Contents
Low risk. These consist of loans with a high investment grade rating equivalent.
Modest risk. These consist of loans where the credit facility greatly exceeds all policy requirements or with policy exceptions that are appropriately mitigated. A secondary source of repayment is verified and considered sustainable. Collateral coverage on these loans is sufficient to fully cover the debt as a tertiary source of repayment. Debt of the borrower is low relative to borrower’s financial strength and ability to pay.
Average risk. These consist of loans where the credit facility meets or exceeds all policy requirements or with policy exceptions that are appropriately mitigated. A secondary source of repayment is available to service the debt. Collateral coverage is more than adequate to cover the debt. The borrower exhibits acceptable cash flow and moderate leverage.
Acceptable risk. These consist of loans with an acceptable primary source of repayment, but a less than preferable secondary source of repayment. Cash flow is adequate to service debt, but there is minimal excess cash flow. Leverage is moderate or high.
"Special mention"(grade 6): Generally these are assets that possess potential weaknesses that warrant management's close attention. These loans may involve borrowers with adverse financial trends, higher debt-to-equity ratios, or weaker liquidity positions, but not to the degree of being considered a “problem loan” where risk of loss may be apparent. Loans in this category are usually performing as agreed, although there may be non-compliance with financial covenants.
"Substandard" (grade 7): These assets are characterized by well-defined credit weaknesses and carry the distinct possibility that the Company will sustain some loss if such weakness or deficiency is not corrected. All loans 90 days or more past due and all loans on nonaccrual status are considered at least "Substandard," unless extraordinary circumstances would suggest otherwise.
"Doubtful"(grade 8): These assets have all the weaknesses inherent in those classified as "Substandard" with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable, but because of certain known factors that may work to the advantage and strengthening of the asset (for example, capital injection, perfecting liens on additional collateral and refinancing plans), classification as an estimated loss is deferred until a more precise status may be determined. Due to the high probability of loss, loans classified as "Doubtful" are placed on nonaccrual status.
"Loss"(grade 9): These assets are considered uncollectible and having such little recoverable value that it is not practical to defer writing off the asset. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather that it is not practicable or desirable to defer writing off the asset, even though partial recovery may be achieved in the future.
Allowance for credit losses on loans
On January 1, 2020, the Company adopted the amendments within ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which changes the impairment model for most financial assets carried at amortized cost from an incurred loss model to an expected loss model. The discussion below reflects the current expected credit loss model methodology. For discussion of the former incurred loss model methodology, refer to the Company's Annual Report on Form 10-K for the year ended December 31, 2019. Credit risk is inherent in the business of extending loans and leases to borrowers for whichand is continuously monitored by management and reflected within the Company must maintain an adequate allowance for credit losses.losses for loans. The allowance for credit losses is established through a provisionan estimate of life-of-loan losses for credit losses recorded to expense. Loans are charged against the Company's loans held for investment. The allowance for credit losses when management believesis a valuation account that is deducted from the contractual principal oramortized cost basis of a loan to present the net amount expected to be collected on the loan. Accrued interest willreceivable on loans, which is included in other assets on the Consolidated Balance Sheet, is excluded from the estimate of expected credit losses. Expected recoveries of amounts previously written off and expected to be written off are included in the valuation account and may not exceed the aggregate of amounts previously written off and expected to be collected. Subsequent recoveries, if any, are credited to the allowance. The allowance is an amount believed adequate to absorb estimated probable losses on existing loans that may become uncollectable, based on evaluation of the collectability of loans and prior credit loss experience, together with other factors.written off. The Company formally re-evaluates and establishes the appropriate level of the allowance for credit losses on a quarterly basis.
The allowance consists of specific and general components. The specific allowance applies to impaired loans. For impaired collateral dependent loans,Determining the reserve is calculated based on the collateral value, net of estimated disposition costs. Generally, the Company obtains independent collateral valuation analysis for each loan every twelve months. Loans not collateral dependent are evaluated based on the expected future cash flows discounted at the original contractual interest rate.
The general allowance covers all non-impaired loans and incorporates several quantitative and qualitative factors, which are used for allappropriateness of the Company's portfolio segments. Quantitative factors include company-specific, ten-year historical net charge-offs stratifiedallowance is complex and requires judgment by loans with similar characteristics. Qualitative factors include: 1) levelsmanagement about the effect of and trends in delinquencies and impaired loans; 2) levels of and trends in charge-offs and recoveries; 3) trends in volume and terms of loans; 4) changes in underwriting standards or lending policies; 5) experience, ability, depth of lending staff; 6) national and local economic trends and conditions; 7) changes in credit concentrations; 8) out-of-market exposures; 9) changes in quality of loan review system; and 10) changes in the value of underlying collateral.
Due to the credit concentrationmatters that are inherently uncertain. In future periods, evaluations of the Company'soverall loan portfolio or particular segments of the loan portfolio, in real estate secured loans,light of the value of collateral is heavily dependent on real estate valuesfactors and forecasts then prevailing, may result in Arizona, Nevada, and California. While management uses the best information available to make its evaluation, future adjustments to the allowance may be necessary if there are significant changes in economic or other conditions. In addition, regulators, as an integral part of their examination processes, periodically review the Bank's allowance for credit losses and may requirecredit loss expense in those future periods. The allowance level is influenced by loan volumes, mix, loan performance metrics, asset quality characteristics, delinquency status, historical credit loss experience, and the Bankinputs and assumptions in economic forecasts, such as macroeconomic inputs, length of reasonable and supportable forecast periods, and reversion methods. The methodology for estimating the amount of expected credit losses reported in the allowance for credit losses has two basic components: first, an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans and; second, a pooled component for estimated expected credit losses for pools of loans that share similar risk characteristics.

Loans that do not share risk characteristics with other loans
Loans that do not share risk characteristics with other loans are evaluated on an individual basis. Loans evaluated individually are not included in the collective evaluation. These loans consist of loans with unique features or loans that no longer share risk characteristics with other pooled loans. The process for determining whether a loan should be evaluated on an individual basis begins with determination of credit rating. All loans graded substandard or worse and all PCD loans, irrespective of credit rating, are specifically reviewed for loss potential and, when deemed appropriate, are assigned a reserve based on an individual evaluation. For these loans, the allowance is based primarily on the fair value of the underlying collateral, utilizing independent third-party appraisals.
Loans that share similar risk characteristics with other loans
In estimating the component of the allowance for credit losses for loans that share similar risk characteristics with other loans, such loans are segregated into loan segments. The Company's primary portfolio segments have changed due to make additionsadoption of the amendments within ASU 2016-13 to align with the methodology applied in estimating the allowance for credit losses under CECL. Loans are designated into loan segments based on loans pooled by product types, business lines, and similar risk characteristics or areas of risk concentration.
In determining the allowance for credit losses, the Company derives an estimate of expected credit losses primarily using an expected loss methodology that incorporates risk parameters (probability of default, loss given default, and exposure at default), which are derived from various vendor models, internally-developed statistical models, or non-statistical estimation approaches. Probability of default is projected in these models or estimation approaches using multiple economic scenarios, whose outcomes are weighted based on the Company's economic outlook and were developed to incorporate relevant information about past events, current conditions, and reasonable and supportable forecasts. With the exception of the Company's residential loan segment, the Company's PD models share a common definition of default, which include loans that are 90 days past due, on nonaccrual status, have a writeoff, or obligor bankruptcy. Input reversion is used for all loan segment models, except for the commercial and industrial and CRE, owner-occupied loan segments. Output reversion is used for the commercial and industrial and CRE, owner-occupied segments by incorporating, after the forecast period, a one-year linear reversion to the allowance based on their judgment about information

availablelong-term reversion rate in year three through the remaining life of the loans within the respective segments. LGDs are typically derived from the Company's historical loss experience. However, for the residential, warehouse lending, and municipal and nonprofit loan segments, where the Company has either zero (or near zero) losses, or has a limited loss history through the last economic downturn, certain non-modeled methodologies are employed. Factors utilized in calculating average LGD vary for each loan segment and are further described below. Exposure at default refers to themthe Company's exposure to loss at the time of their examination. Management regularly reviewsborrower default and is calculated using an amortization schedule based on contractual loan terms, adjusted for a prepayment rate assumption. For most of the Company's loan segments, prepayment rate assumptions are based on a non-modeled approach that calculates the number of loans that were prepaid in full during the period divided by the total number of loans outstanding at the beginning of the period. Prepayment trends are sensitive to interest rates and the macroeconomic environment. Fixed rate loans are more influenced by interest rates, whereas variable rate loans are more influenced by the macroeconomic environment. After the quantitative expected loss estimates are calculated, management then adjusts these estimates to incorporate considerations of current trends and conditions that are not captured in the quantitative loss estimates, through the use of qualitative and/or environmental factors.
The following provides credit quality indicators and risk elements most relevant in monitoring and measuring the allowance for credit losses for each of the loan portfolio segments identified:
Commercial and industrial
The commercial and industrial portfolio segment is comprised of commercial loans that are not collateralized by real estate. The source of repayment of these loans is generally expected to be the income that is generated from the business. The models used to estimate expected credit losses for this loan segment include a combination of a vendor model and an internally-developed model. These models incorporate both market level and company-specific factors such as financial statement variables, adjusted for the current stage of the credit cycle and for the Company's loan performance data such as delinquency, utilization, maturity, and size of the loan commitment under specific macroeconomic scenarios to produce a probability of default. Macroeconomic variables include the Dow Jones Index, credit spread between the BBB Bond Yield and 10-Year Treasury Bond Yield, unemployment rate, and CBOE VIX Index quarterly high. LGD and the prepayment rate assumption for EAD for this loan segment are driven by unemployment levels.

Table of Contents
Commercial real estate, owner-occupied
The CRE, owner-occupied portfolio segment is comprised of commercial loans that are collateralized by real estate, where the primary source of repayment is the business that occupies the property. These loans are typically entered into for the purpose of providing real estate finance or improvement. The primary source of repayment of these loans is the income generated by the business and where rental or sale of the property may provide secondary support for the loan. These loans are sensitive to general economic conditions as well as the market valuation of CRE properties. The probability of default estimate for this loan segment is modeled using the same model as the commercial and industrial loan segment. LGD for this loan segment is driven by property appreciation and the prepayment rate assumption for EAD is driven by unemployment levels.
Commercial real estate, non-owner occupied
The CRE, non-owner occupied segment is comprised of loans that are collateralized by real estate, where the owner is not the primary tenant. These loans are typically entered into for the purpose of financing or the improvement of commercial investment properties. The primary source of repayment of these loans are the rents paid by tenants and where the sale of the property may provide secondary support for the loan. These loans are sensitive to the market valuation of CRE properties, rental rates, and general economic conditions. The vendor model used to estimate expected credit losses for this loan segment projects probabilities of default and exposure at default based on multiple macroeconomic scenarios by modeling how macroeconomic conditions affect the commercial real estate market. Real estate market factors utilized in this model include vacancy rate, rental growth rate, net operating income growth rate, and commercial property price changes for each specific property type. The model then incorporates loan and property-level characteristics including debt coverage, leverage, collateral size, seasoning, and property type. LGD for this loan segment is derived from a non-modeled approach that is driven by property appreciation and the prepayment rate assumption for EAD is driven by the property appreciation for fixed rate loans and unemployment levels for variable rate loans.
Residential
The residential loan portfolio segment is comprised of loans collateralized primarily by first liens on 1-4 residential family properties and home equity lines of credit that are collateralized by either first liens or junior liens on residential properties. The primary source of repayment of these loans is the value of the property and the capacity of the owner to make payments on the loan. Unemployment rates and the market valuation of residential properties will impact the ultimate repayment of these loans. The residential mortgage loan model is a vendor model that projects probability of default, loss given default severity, prepayment rate, and exposure at default to calculate expected losses. The model is intended to capture the borrower's payment behavior during the lifetime of the residential loan by incorporating loan level characteristics such as loan type, coupon, age, loan-to-value, and credit score and economic conditions such as Home Price Index, interest rate, and unemployment rate. A default event for residential loans is defined as 60 days or more past due, with property appreciation as the driver for LGD results. The prepayment rate assumption for exposure at default for residential loans is based on industry prepayment history.
Probability of default for HELOCs is derived from an internally-developed model that projects PD by incorporating loan level information such as FICO score, lien position, balloon payments, and macroeconomic conditions such as property appreciation. LGD for this loan segment is driven by property appreciation and lien position. Exposure at default for HELOCs is calculated based on utilization rate assumptions using a non-modeled approach and incorporates management judgment.
Construction and land development
The construction and land portfolio segment is comprised of loans collateralized by land or real estate, which are entered into for the purpose of real estate development. The primary source of repayment of loans is the eventual sale or refinance of the completed project and where claims on the property provide secondary support for the loan. These loans are impacted by the market valuation of CRE and residential properties and general economic conditions that have a higher sensitivity to real estate markets compared to other real estate loans. Default risk of a property is driven by loan-specific drivers, including loan-to-value, maturity, origination date, and the metropolitan statistical area ("MSA") in which the property is located, among other items. The variables used in the internally-developed model include loan level drivers such as origination loan-to-value, loan maturity, and macroeconomic drivers such as property appreciation, MSA level unemployment rate, and national GDP growth. LGD for this loan segment is driven by property appreciation. The prepayment rate assumption for EAD is driven by the property appreciation for fixed rate loans and unemployment levels for variable rate loans.
Warehouse lending
The warehouse lending portfolio segment consists of loans that have a monitored borrowing base to mortgage companies and similar lenders. These loans are collateralized by real estate notes and mortgages or mortgage servicing rights and the borrowing base of these loans is tightly monitored and controlled by the Company. The primary support for the loan takes the

form of pledged collateral, with secondary support provided by the capacity of the financial institution. The collateral-driven nature of these loans distinguish them from traditional commercial and industrial loans. These loans are impacted by interest rate shocks, residential lending rates, prepayment assumptions, and formulae used in determining the allowance and makes adjustments if required to reflect the current risk profilegeneral real estate stress. As a result of the portfolio.unique loan characteristics, limited historical default and loss experience, and the collateral nature of this loan portfolio segment, the Company uses a non-modeled approach to estimate expected credit losses, leveraging grade information, grade migration history, and management judgment.
Municipal and nonprofit
The municipal and nonprofit portfolio segment consists of loans to local governments, government-operated utilities, special assessment districts, hospitals, schools and other nonprofits. These loans are generally, but not exclusively, entered into for the purpose of financing real estate investment or for refinancing existing debt. Loans are supported by taxes or utility fees, and in some cases tax liens on real estate, operating revenue of the institution, or other collateral support the loans. Unemployment rates and the market valuation of residential properties have an effect on the tax revenues supporting these loans; however, these loans tend to be less cyclical in comparison to similar commercial loans as these loans rely on diversified tax bases. The Company uses a non-modeled approach to estimate expected credit losses, leveraging grade information and historical municipal default rates.
Other
This portfolio consists of those loans not already captured in one of the aforementioned loan portfolio segments, which include, but may not be limited to, overdraft lines for treasury services, credit cards, consumer loans not collateralized by real estate, and small business loans collateralized by residential real estate. The consumer and small business loans are supported by the capacity of the borrower and the valuation of any collateral. General economic factors such as unemployment will have an effect on these loans. The Company uses a non-modeled approach to estimate expected credit losses, leveraging average historical default rates. LGD for this loan segment is driven by unemployment levels and lien position. The prepayment rate assumption for EAD is driven by the BBB corporate spread for fixed rate loans and unemployment levels for variable rate loans.
Off-balance sheet credit exposures, including unfunded loan commitments
The Company maintains a separate allowance for credit losses on off-balance-sheet credit exposures, including unfunded loan commitments, financial guarantees, and letters of credit, which is classified in other liabilities on the Consolidated Balance Sheet. The allowance for credit losses on off-balance sheet credit exposures is adjusted through increases or decreases to the provision for credit loss expense. The estimate includes consideration of the likelihood that funding will occur, an estimate of exposure at default that is derived from utilization rate assumptions using a non-modeled approach, and PD and LGD estimates that are derived from the same models and approaches for the Company's other loan portfolio segments described above as these unfunded commitments share similar risk characteristics with these loan portfolio segments. No credit loss estimate is reported for off-balance sheet credit exposures that are unconditionally cancellable by the Company or for undrawn amounts under such arrangements that may be drawn prior to the cancellation of the arrangement.
Leases (lessee)
At inception, contracts are evaluated to determine whether the contract constitutes a lease agreement. For contracts that are determined to be an operating lease, a corresponding ROU asset and operating lease liability are recorded in separate line items on the Consolidated Balance Sheet. A ROU asset represents the Company’s right to use an underlying asset during the lease term and a lease liability represents the Company’s commitment to make contractually obligated lease payments. Operating lease ROU assets and liabilities are recognized at the commencement date of the lease and are based on the present value of lease payments over the lease term. The measurement of the operating lease ROU asset includes any lease payments made and is reduced by lease incentives that are paid or are payable to the Company. Variable lease payments that depend on an index or rate such as the Consumer Price Index are included in lease payments based on the rate in effect at the commencement date of the lease. Lease payments are recognized on a straight-line basis as part of occupancy expense over the lease term.
As the rate implicit in the lease is not readily determinable, the Company's incremental collateralized borrowing rate is used to determine the present value of lease payments. This rate gives consideration to the applicable FHLB collateralized borrowing rates and is based on the information available at the commencement date. The Company has elected to apply the short-term lease measurement and recognition exemption to leases with an initial term of 12 months or less; therefore, these leases are not recorded on the Company’s Consolidated Balance Sheet, but rather, lease expense is recognized over the lease term on a straight-line basis. The Company’s lease agreements may include options to extend or terminate the lease. These options are included in the lease term when it is reasonably certain that the options will be exercised.

In addition to the package of practical expedients, the Company also elected the practical expedient that allows lessees to make an accounting policy election to not separate non-lease components from the associated lease component, and instead account for them all together as part of the applicable lease component. This practical expedient can be elected separately for each underlying class of asset. The majority of the Company’s non-lease components such as common area maintenance, parking, and taxes are variable, and are expensed as incurred. Variable payment amounts are determined in arrears by the landlord depending on actual costs incurred.
Goodwill and other intangible assets
The Company records as goodwill the excess of the purchase price in a business combination over the fair value of the identifiable net assets acquired in accordance with applicable guidance. The Company performs its annual goodwill and intangibles impairment tests as of October 1 each year, or more often if events or circumstances indicate that the carrying value may not be recoverable. The Company can first elect to assess, through qualitative factors, whether it is more likely than not that goodwill is impaired. If the qualitative assessment indicates potential impairment, a quantitative impairment test is necessary. If, based on the Company will proceed withquantitative test, a two-step process. The first step testsreporting unit's carrying amount exceeds its fair value, a goodwill impairment charge for impairment, while the second step, if necessary, measures the impairment. The resulting impairment amount, if any,this difference is chargedrecorded to current period earnings as non-interest expense.
The Company’s intangible assets consist primarily of core deposit intangible assets that are amortized over periods ranging from 5five to 10 years. The Company considers the remaining useful lives of its core deposit intangible assets each reporting period, as required by ASC 350, Intangibles—Goodwill and Other, to determine whether events and circumstances warrant a revision to the remaining period of amortization. If the estimate of an intangible asset’s remaining useful life has changed, the remaining carrying amount of the intangible asset is amortized prospectively over the revised remaining useful life. The Company hasdid not revisedrevise its estimates of the useful lives of its core deposit intangibles during the three and nine months ended September 30, 2017 and 2016.
Other assets acquired through foreclosure
Other assets acquired through foreclosure consist primarily of properties acquired as a result of,2020 or in-lieu-of, foreclosure. Properties or other assets (primarily repossessed assets formerly leased) are classified as OREO and other repossessed property and are initially reported at fair value of the asset less estimated selling costs. Subsequent adjustments are based on the lower of carrying value or fair value less estimated costs to sell the property. Costs related to the development or improvement of the assets are capitalized and costs related to holding the assets are charged to non-interest expense. Property is evaluated regularly to ensure the recorded amount is supported by its current fair value and valuation allowances.2019.
Treasury Sharesshares
The Company separately presents treasury shares, which represent shares surrendered to the Company equal in value to the statutory payroll tax withholding obligations arising from the vesting of employee restricted stock awards. Treasury shares are carried at cost.
Common stock repurchases
On December 11, 2018, the Company adopted its common stock repurchase program, pursuant to which the Company was authorized to repurchase up to $250.0 million of its shares of common stock through December 31, 2019. The program was renewed through December 2020, authorizing the Company to repurchase up to an additional $250.0 million of its outstanding common stock. All shares repurchased under the plan are retired upon settlement. The Company has elected to allocate the excess of the repurchase price over the par value of its common stock between APIC and retained earnings, with the portion allocated to APIC limited to the amount of APIC that was recorded at the time that the shares were initially issued, which is calculated on a last-in, first-out basis.
Derivative financial instruments
The Company uses interest-rateinterest rate swaps to mitigate interest-rate risk associated with changes to 1) the fair value of certain fixed-rate financial instruments (fair value hedges) and 2) certain cash flows related to future interest payments on variable rate financial instruments (cash flow hedges).
The Company recognizes derivatives as assets or liabilities inon the Consolidated Balance Sheet at their fair value in accordance with ASC 815, Derivatives and Hedging. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. On the date the derivative contract is entered into, the Company designates the derivative as a fair value hedge or cash flow hedge. Derivative instruments designated in a hedge relationship to mitigate exposure to changes in the fair value of an asset or liability attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivative instruments designated in a hedge relationship to mitigate exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges.
Changes in the fair value of a derivative that is designated and qualifies as a fair value hedge, along with changes in the fair value of the hedged asset or liability that are attributable to the hedged risk, are recorded in current-periodcurrent period earnings. For a cash flow hedge, the effective portion of the change in the fair value of the derivative is recorded in AOCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Any ineffective portion of the change in fair value of a cash flow hedge is recognized immediately in non-interest income in the Consolidated Income Statement. Under both the fair value and cash flow hedge scenarios, changesChanges in the fair value of derivatives not considered to be highly effective in hedging the change in fair value or the expected cash flows of the hedged item are recognized in earnings as non-interest income during the period of the change.
The Company documents its hedge relationships, including identification of the hedging instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transaction at the timeafter the derivative contract is

executed. Both atAt inception, and at least quarterly thereafter, the Company assessesperforms a quantitative assessment to determine whether the derivatives used in hedging transactions are highly effective (as defined in the guidance) in offsetting changes in either the fair value or cash flows of the hedged item. Retroactive effectiveness is assessed, as well as the continued expectation that the hedge will remain effective prospectively.
22

Table of Contents
After the initial quantitative assessment is performed, on a quarterly basis, the Company performs a qualitative hedge effectiveness assessment. This assessment takes into consideration any adverse developments related to the counterparty's risk of default and any negative events or circumstances that affect the factors that originally enabled the Company to assess that it could reasonably support, qualitatively, an expectation that the hedging relationship was and will continue to be highly effective. The Company discontinues hedge accounting prospectively when it is determined that a hedge is no longer highly effective. When hedge accounting is discontinued on a fair value hedge that no longer qualifies as an effective hedge, the derivative instrument continues to be reported at fair value inon the Consolidated Balance Sheet, but the carrying amount of the hedged item is no longer adjusted for future changes in fair value. The adjustment to the carrying amount of the hedged item that existed at the date hedge accounting is discontinued is amortized over the remaining life of the hedged item into earnings.
Derivative instruments that are not designated as hedges, so called free-standing derivatives, are reported inon the Consolidated Balance Sheet at fair value and the changes in fair value are recognized in earnings as non-interest income during the period of change.
The Company may in the normal course of business purchase a financial instrument or originate a loan that contains an embedded derivative instrument. Upon purchasing the instrument or originating the loan, the Company assesses whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the financial instrument (i.e., the host contract) and whether a separate instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. When it is determined that the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and a separate instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract and carried at fair value. However, in cases where the host contract is measured at fair value, with changes in fair value reported in current earnings, or the Company is unable to reliably identify and measure an embedded derivative for separation from its host contract, the entire contract is carried inon the Consolidated Balance Sheet at fair value and is not designated as a hedging instrument.
Off-balance sheet instruments
In the ordinary course of business, the Company has entered into off-balance sheet financial instrument arrangements consisting of commitments to extend credit and standby letters of credit. Such financial instruments are recorded in the Consolidated Financial Statements when they are funded. They involve, to varying degrees, elements of credit risk in excess of amounts recognized on the Consolidated Balance Sheet. Losses could be experienced when the Company is contractually obligated to make a payment under these instruments and must seek repayment from the borrower, which may not be as financially sound in the current period as they were when the commitment was originally made. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract and, in certain instances, may be unconditionally cancelable. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The Company enters into credit arrangements that generally provide for the termination of advances in the event of a covenant violation or other event of default. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the party. The commitments are collateralized by the same types of assets used as loan collateral.
The Company also has off-balance sheet arrangements related to its derivative instruments. Derivative instruments are recognized in the Consolidated Financial Statements at fair value and their notional values are carried off-balance sheet. See "Note 8. Derivatives and Hedging Activities" of these Notes to Unaudited Consolidated Financial Statements for further discussion.
Fair values of financial instruments
The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities. ASC 820, Fair Value Measurement, establishes a framework for measuring fair value and a three-level valuation hierarchy for disclosure of fair value measurement, and also sets forth disclosure requirements for fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The Company uses various valuation approaches, including market, income, and/or cost approaches. ASC 820 establishes 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 the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would consider in pricing the
23

Table of Contents
asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the reliability of inputs, as follows:
Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
Level 2 - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, prepayment speeds, volatilities, etc.) or model-based valuation techniques where all significant assumptions are observable, either directly or indirectly, in the market.
Level 3 - Valuation is generated from model-based techniques where one or more significant inputs are not observable, either directly or indirectly, in the market. These unobservable assumptions reflect the Company’s own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques may include use of matrix pricing, discounted cash flow models, and similar techniques.
The availability of observable inputs varies based on the nature of the specific financial instrument. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety.
Fair value is a market-based measure considered from the perspective of a market participant who may purchase the asset or assume the liability, rather than an entity-specific measure. When market assumptions are available, ASC 820 requires that the Company make assumptions regarding the assumptions that market participants would use to estimate the fair value of the financial instrument at the measurement date.
ASC 825, Financial Instruments, requires disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate that value.
Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent limitations in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates presented herein are not necessarily indicative of the amounts the Company could have realized in a sales transaction at September 30, 2020 and December 31, 2019. The estimated fair value amounts for September 30, 2020 and December 31, 2019 have been measured as of period-end, and have not been re-evaluated or updated for purposes of these Unaudited Consolidated Financial Statements subsequent to those dates. As such, the estimated fair values of these financial instruments subsequent to the reporting date may be different than the amounts reported at period-end.
The information in "Note 12. Fair Value Accounting" of these Notes to Unaudited Consolidated Financial Statements should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only required for a limited portion of the Company’s assets and liabilities.
Due to the wide range of valuation techniques and the degree of subjectivity used in making the estimate, comparisons between the Company’s disclosures and those of other companies or banks may not be meaningful.
The following methods and assumptions were used by the Company in estimating the fair value of its financial instruments:
Cash, cash equivalents, and restricted cash
The carrying amounts reported on the Consolidated Balance Sheet for cash and due from banks approximate their fair value.
Money market investments
The carrying amounts reported on the Consolidated Balance Sheet for money market investments approximate their fair value.
24

Table of Contents
Investment securities
The fair values of CRA investments, exchange-listed preferred stock, trust preferred securities, and certain corporate debt securities are based on quoted market prices and are categorized as Level 1 in the fair value hierarchy.
The fair values of debt securities are primarily determined based on matrix pricing. Matrix pricing is a mathematical technique that utilizes observable market inputs including, for example, yield curves, credit ratings, and prepayment speeds. Fair values determined using matrix pricing are generally categorized as Level 2 in the fair value hierarchy. For a small subset of securities, other pricing sources are used, including observed prices on publicly traded securities and dealer quotes.
Restricted stock
WAB is a member of the Federal Reserve System and the FHLB and, accordingly, maintains investments in the capital stock of the FRB and the FHLB. These investments are carried at cost since no ready market exists for them, and they have no quoted market value. The Company conducts a periodic review and evaluation of its restricted stock to determine if any impairment exists. The fair values of these investments have been categorized as Level 2 in the fair value hierarchy.
Loans
The fair value of loans is estimated based on discounted cash flows using interest rates currently being offered for loans with similar terms to borrowers with similar credit quality and adjustments that the Company believes a market participant would consider in determining fair value based on a third-party independent valuation. As a result, the fair value for loans is categorized as Level 2 in the fair value hierarchy, excluding collateral dependent and impaired loans, which are categorized as Level 3.
Accrued interest receivable and payable
The carrying amounts reported on the Consolidated Balance Sheet for accrued interest receivable and payable approximate their fair values.
Derivative financial instruments
All derivatives are recognized on the Consolidated Balance Sheets at their fair value. The fair value for derivatives is determined based on market prices, broker-dealer quotations on similar products, or other related input parameters. As a result, the fair values have been categorized as Level 2 in the fair value hierarchy.
Deposits
The fair value disclosed for demand and savings deposits is by definition equal to the amount payable on demand at their reporting date (that is, their carrying amount) as these deposits do not have a contractual term. The carrying amount for variable rate deposit accounts approximates their fair value. Fair values for fixed rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on these deposits. The fair value measurement of the deposit liabilities is categorized as Level 2 in the fair value hierarchy.
FHLB advances and customer repurchase agreements
The fair values of the Company’s borrowings are estimated using discounted cash flow analyses, based on the market rates for similar types of borrowing arrangements. The FHLB advances and customer repurchase agreements have been categorized as Level 2 in the fair value hierarchy due to their short durations.
Subordinated debt
The fair value of subordinated debt is based on the market rate for the respective subordinated debt security. Subordinated debt has been categorized as Level 2 in the fair value hierarchy.
Junior subordinated debt
Junior subordinated debt is valued based on a discounted cash flow model which uses as inputs Treasury Bond rates and the 'BB' and 'BBB' rated financial indexes. Junior subordinated debt has been categorized as Level 3 in the fair value hierarchy.
25

Table of Contents
Off-balance sheet instruments
The fair value of the Company’s off-balance sheet instruments (lending commitments and letters of credit) is based on quoted fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements, and the counterparties’ credit standing.
Income taxes
The Company is subject to income taxes in the United States and files a consolidated federal income tax return with all of its subsidiaries, with the exception of BW Real Estate, Inc. Deferred income taxes are recorded to reflect the effects of temporary differences between the financial reporting carrying amounts of assets and liabilities and their income tax bases using enacted tax rates that are expected to be in effect when the taxes are actually paid or recovered. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.
Net deferred tax assets are recorded to the extent that these assets will more-likely-than-not be realized. In making these determinations, all available positive and negative evidence is considered, including scheduled reversals of deferred tax liabilities, tax planning strategies, projected future taxable income, and recent operating results. If it is determined that deferred income tax assets to be realized in the future are in excess of their net recorded amount, an adjustment to the valuation allowance will be recorded, which will reduce the Company's provision for income taxes.
A tax benefit from an unrecognized tax benefit may be recognized when it is more-likely-than-not that the position will be sustained upon examination, including related appeals or litigation, based on technical merits. Income tax benefits must meet a more-likely-than-not recognition threshold at the effective date to be recognized.
Interest and penalties related to unrecognized tax benefits are recognized as part of the provision for income taxes in the Consolidated Income Statement. Accrued interest and penalties are included in the related tax liability line with other liabilities inon the Consolidated Balance Sheet. See "Note 11.10. Income Taxes" of these Notes to Unaudited Consolidated Financial Statements for further discussion on income taxes.
Off-balance sheet instrumentsNon-interest income
In the ordinary courseNon-interest income includes service charges and fees, income from equity investments, card income, foreign currency income, income from bank owned life insurance, lending related income, net gain or loss on sales of business, the Company has entered into off-balance sheet financial instrument arrangements consisting of commitments to extend credit and standby letters of credit. Such financial instruments are recorded in the Consolidated Financial Statements when they are funded. They involve, to varying degrees, elements of credit risk in excess of amounts recognized in the Consolidated Balance Sheet. Losses would be experienced when the Company is contractually obligated to make a payment under these instruments and must seek repayment from the borrower, which may not be as financially sound in the current period as they were when the commitment was originally made. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration datesinvestment securities, net fair value gain or other termination clauses and may require payment of a fee. The Company enters into credit arrangements that generally provide for the termination of advances in the event of a covenant violation or other event of default. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthinessloss adjustments on a case-by-case

basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the party. The commitments are collateralized by the same types of assets used as loan collateral.
As with outstanding loans, the Company applies qualitative factors and utilization rates to its off-balance sheet obligations in determining an estimate of losses inherent in these contractual obligations. The estimate for credit losses on off-balance sheet instruments is included in other liabilities and the charge to income that establishes this liability is included in non-interest expense.
The Company also has off-balance sheet arrangements related to its derivative instruments. Derivative instruments are recognized in the Consolidated Financial Statementsmeasured at fair value, and their notional valuesother income. Service charges and fees consist of fees earned from performance of account analysis, general account services, and other deposit account services. These fees are carried off-balance sheet.recognized as the related services are provided in accordance with ASC 606, Revenue from Contracts with Customers. Income from equity investments includes gains on equity warrant assets, SBIC equity income, and success fees. Card income includes fees earned from customer use of debit and credit cards, interchange income from merchants, and international charges. Card income is generally within the scope of ASC 310, Receivables; however, certain processing transactions for merchants, such as interchange fees, are within the scope of ASC 606. Foreign currency income represents fees earned on the differential between purchases and sales of foreign currency on behalf of the Company’s clients. Income from bank owned life insurance is accounted for in accordance with ASC 325, Investments - Other. Lending related income includes fees earned from gains or losses on the sale of loans, SBA income, and letter of credit fees. Gains and losses on the sale of loans and SBA income are recognized pursuant to ASC 860, Transfers and Servicing. Net unrealized gains or losses on assets measured at fair value represent fair value changes in equity securities and are accounted for in accordance with ASC 321, Investments - Equity Securities. Fees related to standby letters of credit are accounted for in accordance with ASC 440, Commitments. Other income includes operating lease income, which is recognized on a straight-line basis over the lease term in accordance with ASC 842, Leases. Net gain or loss on sales/valuations of repossessed and other assets is presented as a component of non-interest expense, but may also be presented as a component of non-interest income in the event that a net gain is recognized. Net gain or loss on sales of repossessed and other assets are accounted for in accordance with ASC 610, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets. See "Note 9. Derivatives and Hedging Activities"14. Revenue from Contracts with Customers" of these Notes to Unaudited Consolidated Financial Statements for further discussion.
Fair values of financial instruments
The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities. ASC 820, Fair Value Measurement, establishes a framework for measuring fair value and a three-level valuation hierarchy for disclosure of fair value measurement, as well as enhances disclosure requirements for fair value measurements. The valuation hierarchy is based upon the transparency of inputsdetails related to the valuation of an asset or liability as of the measurement date. The Company uses various valuation approaches, including market, income, and/or cost approaches. ASC 820 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputsnature 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 the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would consider in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the reliability of inputs, as follows:
Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
Level 2 - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, prepayment speeds, volatilities, etc.) or model-based valuation techniques where all significant assumptions are observable, either directly or indirectly, in the market.
Level 3 - Valuation is generated from model-based techniques where one or more significant inputs are not observable, either directly or indirectly, in the market. These unobservable assumptions reflect the Company’s own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques may include use of matrix pricing, discounted cash flow models, and similar techniques.
The availability of observable inputs varies based on the nature of the specific financial instrument. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety.
Fair value is a market-based measure considered from the perspective of a market participant who may purchase the asset or assume the liability rather than an entity-specific measure. When market assumptions are available, ASC 820 requires the Company to make assumptions regarding the assumptions that market participants would use to estimate the fair value of the financial instrument at the measurement date.
ASC 825, Financial Instruments, requires disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate that value.
Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent limitations in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates presented herein are not necessarily indicative of the amounts the Company could have realized in a sales transaction at

September 30, 2017 and 2016. The estimated fair value amounts for September 30, 2017 and 2016 have been measured as of period-end, and have not been re-evaluated or updated for purposes of these Consolidated Financial Statements subsequent to those dates. As such, the estimated fair values of these financial instruments subsequent to the reporting date may be different than the amounts reported at period-end.
The information in "Note 13. Fair Value Accounting" in these Notes to Unaudited Consolidated Financial Statements should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only required for a limited portion of the Company’s assets and liabilities.
Due to the wide range of valuation techniques and the degree of subjectivity used in making the estimate, comparisons between the Company’s disclosures and those of other companies or banks may not be meaningful.
The following methods and assumptions were used by the Company in estimating the fair value of its financial instruments:
Cash and cash equivalents
The carrying amounts reported in the Consolidated Balance Sheets for cash and due from banks approximate their fair value.
Money market investments
The carrying amounts reported in the Consolidated Balance Sheets for money market investments approximate their fair value.
Investment securities
The fair values of CRA investments, exchange-listed preferred stock, and certain corporate debt securities are based on quoted market prices and are categorized as Level 1 in the fair value hierarchy.
The fair values of other investment securities were determined based on matrix pricing. Matrix pricing is a mathematical technique that utilizes observable market inputs including, for example, yield curves, credit ratings, and prepayment speeds. Fair values determined using matrix pricing are generally categorized as Level 2 in the fair value hierarchy.
During the year ended December 31, 2016, the Company's CDO securities were transferred from Level 3 to Level 2 as a result of an increase in the availability and reliability of the observable inputs utilized in the securities' fair value measurement. Previously, quoted prices and quoted prices for similar assets were not available. Therefore, the Company would engage a third party to estimate the future cash flows and discount rate using third party quotes adjusted based on assumptions a market participant would assume necessary for each specific security, which resulted in fair values for these securities being categorized as Level 3 in the fair value hierarchy.
Restricted stock
WAB is a member of the Federal Reserve System and the FHLB and, accordingly, maintains investments in the capital stock of the FRB and the FHLB. WAB also maintains an investment in its primary correspondent bank. These investments are carried at cost since no ready market exists for them, and they have no quoted market value. The Company conducts a periodic review and evaluation of its restricted stock to determine if any impairment exists. The fair values of these investments have been categorized as Level 2 in the fair value hierarchy.
Loans
The fair value of loans is estimated based on discounted cash flows using interest rates currently being offered for loans with similar terms to borrowers with similar credit quality and adjustments that the Company believes a market participant would consider in determining fair value based on a third party independent valuation. As a result, the fair value for loans is categorized as Level 2 in the fair value hierarchy, excluding impaired loans which are categorized as Level 3.
Accrued interest receivable and payable
The carrying amounts reported in the Consolidated Balance Sheets for accrued interest receivable and payable approximate their fair value.

Derivative financial instruments
All derivatives are recognized in the Consolidated Balance Sheets at their fair value. The fair value for derivatives is determined based on market prices, broker-dealer quotations on similar products, or other related input parameters. As a result, the fair values have been categorized as Level 2 in the fair value hierarchy.
Deposits
The fair value disclosed for demand and savings deposits is by definition equal to the amount payable on demand at their reporting date (that is, their carrying amount), which the Company believes a market participant would consider in determining fair value. The carrying amount for variable-rate deposit accounts approximates their fair value. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on these deposits. The fair value measurement of the deposit liabilities is categorized as Level 2 in the fair value hierarchy.
FHLB advances and customer repurchase agreements
The fair values of the Company’s borrowings are estimated using discounted cash flow analyses, based on the market rates for similar types of borrowing arrangements. The FHLB advances and customer repurchase agreements have been categorized as Level 2 in the fair value hierarchy due to their short durations.
Subordinated debt
The fair value of subordinated debt is based on the market rate for the respective subordinated debt security. Subordinated debt has been categorized as Level 3 in the fair value hierarchy.
Junior subordinated debt
Junior subordinated debt is valued based on a discounted cash flow model which uses as inputs Treasury Bond rates and the 'BB' rated financial index. Junior subordinated debt has been categorized as Level 3 in the fair value hierarchy.
Off-balance sheet instruments
The fair value of the Company’s off-balance sheet instruments (lending commitments and standby letters of credit) is based on quoted fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements, and the counterparties’ credit standing.
Recent accounting pronouncements
In May 2014, the FASB issued guidance within ASU 2014-09, Revenue from Contracts with Customers. The amendments in ASU 2014-09 to Topic 606, Revenue from Contracts with Customers, creates a common revenue standard and clarifies the principles for recognizing revenue that can be applied consistently across various transactions, industries, and capital markets. The amendments in the ASU clarify that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. As part of that principle, the entity should identify the contract(s) with the customer, identify the performance obligation(s) of the contract, determine the transaction price, allocate that transaction price to the performance obligation(s) of the contract, and then recognize revenue when or as the entity satisfies the performance obligation(s). In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date, which deferred the original effective date of ASU No. 2014-09 by one year. Accordingly, the amendments in ASU No. 2014-09 will be effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that annual reporting period. The amendments will be applied through the election of one of two retrospective methods. Substantially all of the Company's revenue is generated from interest income related to loans and investment securities, which are not within the scope of this guidance. The contracts that are within the scope of this guidance include service charges and fees on deposit accounts and warrant related income. The Company has completed its review of contracts and other agreements that are within the scope of this guidance and did not identify any material changes to the timing of revenue recognition. The Company will adopt the amendments beginning January 1, 2018 through use of the modified retrospective transition method and expects to expand its qualitative and quantitative disclosures ofrecognition for non-interest income revenue recognition upon adoption.

In January 2016, the FASB issued guidance within ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in ASU 2016-01 to Subtopic 825-10, Financial Instruments, contain the following elements: 1) requires equity investments to be measured at fair value with changes in fair value recognized in net income; 2) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; 3) eliminates the requirement for public entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; 4) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; 5) requires an entity to present separately in OCI the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; 6) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or accompanying notes to the financial statements; 7) clarifies that the entity should evaluate the need for a valuation allowance on a deferred tax asset related to AFS securities in combination with the entity's other deferred tax assets. The amendments are effective for fiscal years beginning after December 15, 2017, and for interim periods within those fiscal years. Except for the early application of the amendment noted in item 5) above, which the Company elected to early adopt effective January 1, 2015 as discussed in the Company's Annual Report on Form 10-K for the year ended December 31, 2015, early adoption of the amendments in this Update is not permitted. As discussed in item 1) above, changes in the fair value of the Company's equity investments, which consist of preferred stock of $96.1 million at September 30, 2017, will be recognized in net income, rather than in AOCI. As a result, there may be greater volatility in earnings each reporting period related to fair value changes. However, as preferred stock is less than 3% of the Company's total AFS portfolio, the adoption of this amendment and the other amendments in this guidance are not expected to have a material impact on the Company's Consolidated Financial Statements.
In February 2016, the FASB issued guidance within ASU 2016-02, Leases. The amendments in ASU 2016-02 to Topic 842, Leases, require lessees to recognize the lease assets and lease liabilities arising from operating leases in the statement of financial position. The accounting applied by a lessor is largely unchanged from that applied under previous GAAP. The amendments in this Update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. Management is in the early stages of its implementation assessment, which includes identifying the population of the Company's leases that arestreams within the scope of the new guidance, gathering all key lease data, and considering new lease software options that will facilitate applicationstandard.

Table of the new accounting requirements.Contents
In June 2016, the FASB issued guidance within ASU 2016-13, Measurement of Credit Losses on Financial Instruments. The amendments in ASU 2016-13 to Topic 326, Financial Instruments - Credit Losses, require that an organization measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The ASU also requires enhanced disclosures, including qualitative and quantitative disclosures that provide additional information about the amounts recorded in the financial statements. Additionally, the ASU amends the accounting for credit losses on AFS debt securities and purchased financial assets with credit deterioration. The amendments in this Update are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Management has formed a Steering Committee and established an implementation team made up of subject matter experts across different functions within the Company, including Finance, Risk, Credit, and IT, that will facilitate all phases of planning and implementation of the new guidance. The team is working with certain external consultants and is in the final stages of completing its gap assessment. The team has also evaluated numerous modeling packages and has made preliminary decisions on various model approaches. Further, the team is also in the process of evaluating its control framework to identify risks resulting from new processes, judgments, and data.
In August 2016, the FASB issued guidance within ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments. The amendments in ASU 2016-15 to Topic 230, Statement of Cash Flows, provide guidance on eight specific cash flow classification issues: 1) debt prepayment or debt extinguishment costs; 2) settlement of zero-coupon debt instruments; 3) contingent consideration payments made after a business combination; 4) proceeds from the settlement of insurance claims; 5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; 6) distributions received from equity method investments; 7) beneficial interest in securitization transactions; and 8) separately identifiable cash flows and the application of the predominance principle. The amendments in this Update are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. However, an entity is required to adopt all of the amendments in the same period. The amendments in this Update should be applied using a retrospective transition method to each period presented. The adoption of this guidance is not expected to have a significant impact on the Company's Consolidated Statement of Cash Flows.
In January 2017, the FASB issued guidance within ASU 2017-01, Clarifying the Definition of a Business. The amendments in ASU 2017-01 to Topic 805, Business Combinations, clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or

businesses. The amendments in this Update should be applied prospectively and are effective for annual periods beginning after December 31, 2017, including interim periods within those periods. The adoption of this guidance is not expected to have a material impact on the Company's Consolidated Financial Statements.
In January 2017, the FASB issued guidance within ASU 2017-04, Simplifying the Test for Goodwill Impairment. The amendments in ASU 2017-04 to Topic 350, Intangibles - Goodwill and Other, modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. Accordingly, the amendments eliminate Step 2 from the goodwill impairment test because goodwill impairment will no longer be determined by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendments in this Update should be applied on a prospective basis and are effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. The adoption of this guidance is not expected to have a material impact on the Company's Consolidated Financial Statements.
In February 2017, the FASB issued guidance within ASU 2017-05, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets. The amendments in ASU 2017-05 to Subtopic 610-20, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets, clarify the scope of Subtopic 610-20 and add guidance for partial sales of nonfinancial assets, including partial sales of real estate. Under current GAAP, there are several different accounting models to evaluate whether the transfer of certain assets qualify for sale treatment. The new standard reduces the number of potential accounting models that might apply and clarifies which model does apply in various circumstances. An entity may elect to apply the amendments in this Update either retrospectively to each period presented in the financial statements or, retrospectively with a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The amendments in this Update are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Early adoption is permitted for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The adoption of this guidance is not expected to have a material impact on the Company's Consolidated Financial Statements.
In March 2017, the FASB issued guidance within ASU 2017-08, Premium Amortization on Purchased Callable Debt Securities. The amendments in ASU 2017-08 to Subtopic 310-20, Receivables-Nonrefundable Fees and Other Costs, shorten the amortization period for certain purchased callable debt securities held at a premium to the earliest call date, which more closely align the amortization period of premiums and discounts to expectations incorporated in market pricing on the underlying securities. Under current GAAP, entities generally amortize the premium as an adjustment of yield over the contractual life of the instrument. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments in this Update should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. The adoption of this guidance is not expected to have a material impact on the Company's Consolidated Financial Statements.
In May 2017, the FASB issued guidance within ASU 2017-09, Scope of Modification Accounting. The amendments in ASU 2017-09 to Topic 718, Compensation - Stock Compensation, provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. An entity should account for the effects of a modification unless all of the following conditions are met: the fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified; the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; and the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The amendments in this Update should be applied prospectively to an award modified on or after the adoption date. The amendments in this Update are effective for annual periods, and interim periods within those annual periods, beginning after December 31, 2017. Early adoption is permitted, including adoption in any interim period. The adoption of this guidance is not expected to have a material impact on the Company's Consolidated Financial Statements.
In August 2017, the FASB issued guidance within ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. The amendments in ASU 2017-12 to Topic 815, Derivatives and Hedging, is intended to more closely align hedge accounting with companies' risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. The guidance also amends the presentation and disclosure requirements and changes how companies assess effectiveness. Under the new guidance, public companies will have until the end of the first quarter in which a hedge is designated to perform an initial assessment of a hedge's effectiveness. After initial qualification, the new

guidance permits a qualitative effectiveness assessment for certain hedges instead of a quantitative test if the company can reasonably support an expectation of high effectiveness throughout the term of the hedge. Additional disclosures include cumulative basis adjustments for fair value hedges and the effect of hedging on individual income statement line items. The amendments in this Update are effective for fiscal years beginning after December 15, 2018, and interim period within those fiscal years. Early adoption is permitted in any interim period after issuance of the Update. Management is in the process of evaluating the effects that the standard is expected to have on the Company's Consolidated Financial Statements and related disclosures.
Recently adopted accounting guidance
In November 2015, the FASB issued guidance within ASU 2015-17, Income Taxes. The amendments in ASU 2015-17 to Topic 740, Income Taxes, changes the presentation of deferred income tax liabilities and assets, from previously bifurcated current and noncurrent, to a single noncurrent amount on the classified statement of financial position. The amendment was effective for the annual period ending after December 15, 2016, and for and interim periods within those annual periods. The adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements.
In March 2016, the FASB issued guidance within ASU 2016-05, Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships. The amendments in ASU 2016-05 to Topic 815, Derivatives and Hedging, clarify that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under Topic 815 does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. The amendments in this Update were effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The adoption of this guidance did not have a material impact on the Company's Consolidated Financial Statements.

Securities measured at fair value        
Residential MBS issued by GSEs       $1,053
During the nine months endedSecurities with carrying amounts of approximately $830.4 million and $962.5 million at September 30, 2017, the Company sold all of its investment securities measured at fair value. No significant gain or loss was recognized upon sale of these securities. For additional information on the fair value changes of securities measured at fair value, see the trading securities table in "Note 13. Fair Value Accounting" of these Notes to Unaudited Consolidated Financial Statements.

The Company conducts an OTTI analysis on a quarterly basis. The initial indication of OTTI for both debt and equity securities is a decline in the market value below the amount recorded for an investment, and taking into account the severity and duration of the decline. Another potential indication of OTTI is a downgrade below investment grade. In determining whether an impairment is OTTI, the Company considers the length of time and the extent to which the market value has been below cost, recent events specific to the issuer, including investment downgrades by rating agencies and economic conditions of its industry, and the Company’s ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery. For marketable equity securities, the Company also considers the issuer’s financial condition, capital strength, and near-term prospects.
For debt securities, for the purpose of an OTTI analysis, the Company also considers the cause of the price decline (general level of interest rates, credit spreads, and industry and issuer-specific factors), the issuer’s financial condition, near-term prospects, and current ability to make future payments in a timely manner, as well as the issuer’s ability to service debt, and any change in agencies’ ratings at the evaluation date from the acquisition date and any likely imminent action.
The Company has reviewed securities for which there is an unrealized loss in accordance with its accounting policy for OTTI described above and determined that there are no impairment charges for the three and nine months ended September 30, 2017 and 2016. The Company does not consider any securities to be other-than-temporarily impaired as of September 30, 20172020 and December 31, 2016. No assurance can be made that OTTI will not occur in future periods.
Information pertaining to securities with gross unrealized losses at September 30, 2017 and December 31, 2016, aggregated2019, respectively, were pledged for various purposes as required or permitted by investment category and length of time that individual securities have been in a continuous loss position follows: law.

On January 1, 2020, the Company adopted the amendments within ASU 2016-13, which replaces the legacy US GAAP OTTI model with a credit loss model. The credit loss model under ASC 326-30, applicable to AFS debt securities, requires recognition of credit losses through an allowance account, but retains the concept from the OTTI model that credit losses are recognized once securities become impaired. For a detailed discussion of the impact of adoption of ASU 2016-13 and information related to investment securities, including accounting policies and methodologies used to estimate the allowance for credit losses on securities, see "Note 1. Summary of Significant Accounting Policies."

These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies, and have a long history of no credit losses. As the Company does not intend to sell these securities and it is more likely than not that the Company will not be required to sell the securities prior to their anticipated recovery, no credit losses have been recognized on these securities during the three and nine months ended September 30, 2020.
Qualitative factors used in the foreseeable future, noneCompany's credit loss assessment of its securities that are not guaranteed by the U.S. government included consideration of any adverse conditions related to a specific security, industry, or geographic region of its securities, any credit ratings below investment grade, the payment structure of the securities describedsecurity and the likelihood of the issuer to be able to make payments that increase in the above tablefuture, and failure of the issuer to make any scheduled principal or interest payments. For the Company's corporate debt, municipal, and tax-exempt securities, the Company also considered various metrics of the issuer including days of cash on hand, the ratio of long-term debt to total assets, the net change in this paragraph are deemedcash between reporting periods, and consideration of any breach in covenant requirements. For the Company's private label residential MBS, the Company also considered metrics such as securitization risk weight factor, current credit support, whether there were any mortgage principal

3. LOANS, LEASES AND ALLOWANCE FOR CREDIT LOSSES
On January 1, 2020, the Company adopted the amendments within ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. Accordingly, the Company's financial results for reporting periods beginning after January 1, 2020 are presented in accordance with ASC 326 while prior period amounts have not been adjusted and continue to be reported in accordance with legacy GAAP. For a detailed discussion of the impact of adoption of ASU 2016-13 and information related to loans and credit quality, including accounting policies and methodologies used to estimate the allowance for credit losses on loans, see "Note 1. Summary of Significant Accounting Policies."
The Company's primary portfolio segments have changed to align with the methodology applied in estimating the allowance for credit losses under CECL. In addition, as the concept of impaired loans does not exist under CECL, disclosures that related solely to impaired loans have been removed.
The composition of the Company’sCompany's held for investment loan portfolio is as follows:

The reduction in interest income associated with loans on non-accrualnonaccrual status was approximately $0.7$1.7 million and $0.6$0.7 million for the three months ended September 30, 20172020 and 2016,2019, respectively, and$1.8 $4.1 million and $1.5 million for the nine months ended September 30, 20172020 and 2016,2019, respectively.
The Company utilizes an internal asset classification system as a means of reporting problem and potential problem loans. Under the Company’s risk rating system, the Company classifies problem and potential problem loans as Special Mention, Substandard, Doubtful, and Loss. Substandard loans include those characterized by well-defined weaknesses and carry the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Loans classified as Doubtful, or risk rated nine, have all the weaknesses inherent in those classified as Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The final rating of Loss covers loans considered uncollectible and having such little recoverable value that it is not practical to defer writing off the asset. Loans that do not currently expose the Company to sufficient risk to warrant classification in one of the aforementioned categories, but possess weaknesses that warrant management’s close attention, are deemed to be Special Mention. Risk ratings are updated, at a minimum, quarterly.

The following tables present gross loans by risk rating:

A valuation allowance is established for an impaired loan when the fair value of the loan is less than the recorded investment. In certain cases, portions of impaired loans are charged-off to realizable value instead of establishing a valuation allowance and are included, when applicable, in the table above as “Impaired loans without a specific valuation allowance under ASC 310.” However, before concluding that an impaired loan needs no associated valuation allowance, an assessment is made to consider all available and relevant information for the method used to evaluate impairment and the type of loan being assessed. The valuation allowance disclosed above is included in the allowance for credit losses reported in the Consolidated Balance Sheets as of September 30, 2017 and December 31, 2016.

Troubled Debt Restructurings
A TDR loan is a loan on which the Company, for reasons related to a borrower’s financial difficulties, grants a concession to the borrower that the Company would not otherwise consider. The loan terms that have been modified or restructured due to a borrower’s financial situation include, but are not limited to, a reduction in the stated interest rate, an extension of the maturity or renewal of the loan at an interest rate below current market, a reduction in the face amount of the debt, a reduction in the accrued interest, or deferral of interest payments. The majority of the Company's modifications are extensions in terms or deferral of payments which result in no lost principal or interest followed by reductions in interest rates or accrued interest. A TDR loan is also considered impaired. Consistent with regulatory guidance, a TDR loan that is subsequently modified in another restructuring agreement but has shown sustained performance and classification as a TDR, will be removed from TDR status provided that the modified terms were market-based at the time of modification.
As of September 30, 2020, the Company's TDR loans totaled $60.8 million. During the three months ended September 30, 2017,2020, the Company had two20 new TDR loans with a recorded investment of $1.9$25.0 million. During the nine months ended September 30, 2017,2020, the Company had three22 new TDR loanloans with a recorded investment of $6.8$35.7 million.The Company has $2.7 million allowance allocated to these loans as of September 30, 2020 and has committed to lend additional amounts totaling $4.2 million.

The CARES Act, signed into law on March 27, 2020, permits financial institutions to suspend requirements under GAAP for loan modifications to borrowers affected by COVID-19 that would otherwise be characterized as TDRs and suspend any determination related thereto if (i) the loan modification is made between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the end of the coronavirus emergency declaration and (ii) the applicable loan was not more than 30 days past due as of December 31, 2019. In addition, federal bank regulatory authorities have issued guidance to encourage financial institutions to make loan modifications for borrowers affected by COVID-19 and have assured financial institutions that they will neither receive supervisory criticism for such prudent loan modifications, nor be required by examiners to automatically categorize COVID-19-related loan modifications as TDRs. The Company is applying this guidance to qualifying loan modifications.
The terms of certain other loans were modified during the three and nine months ended September 30, 2020 that did not meet the definition of a TDR. The modification of these loans involved either a modification of the terms of a loan to borrowers who were not experiencing financial difficulties prior to the pandemic or a delay in a payment that was considered to be insignificant.

9.8. DERIVATIVES AND HEDGING ACTIVITIES
The Company is a party to various derivative instruments. Derivative instruments are contracts between two or more parties that have a notional amount and an underlying variable, require a small or no initial investment, and allow for the net settlement of positions. A derivative’s notional amount serves as the basis for the payment provision of the contract and takes the form of units, such as shares or dollars. A derivative’s underlying variable is a specified interest rate, security price, commodity price, foreign exchange rate, index, or other variable. The interaction between the notional amount and the underlying variable determines the number of units to be exchanged between the parties and influences the fair value of the derivative contract.
The primary type of derivatives that the Company uses are interest rate swaps. Generally, these instruments are used to help manage the Company's exposure to interest rate risk and meet client financing and hedging needs.
Derivatives are recorded at fair value inon the Consolidated Balance Sheets, after taking into account the effects of bilateral collateral and master netting agreements. These agreements allow the Company to settle all derivative contracts held with the same counterparty on a net basis, and to offset net derivative positions with related cash collateral, where applicable.
As of September 30, 2017,2020, December 31, 2016,2019, and September 30, 2016,2019, the Company does not have any significant outstanding cash flow hedges or free-standing derivatives.hedges.
Derivatives Designated in Hedge Relationships
The Company utilizes derivatives that have been designated as part of a hedge relationship in accordance with the applicable accounting guidance to minimize the exposure to changes in benchmark interest rates and volatility of net interest income and EVE to interest rate fluctuations. The primary derivative instruments used to manage interest rate risk are interest rate swaps, which convert the contractual interest rate index of agreed-upon amounts of assets and liabilities (i.e., notional amounts) from either a fixed rate to another interesta floating rate, index.or from a floating rate to a fixed rate.
The Company has entered into pay fixed/receive variable interest rate swaps designated as fair value hedges of certain fixed rate loans. As a result, the Company receives variable-rate interest payments in exchange for making fixed-rate payments over the lives of the contracts without exchanging the notional amounts.
The Company has also entered into receive fixed/pay variable/receive fixedvariable interest rate swaps, designated as fair value hedges on its fixed rate 2015 and 2016 subordinated debt offerings. As a result, the Company is paying a floating rate of three-month LIBOR plus 3.16% and is receiving semi-annual fixed payments of 5.00% to match the payments on the $150.0 million subordinated debt. For the fair value hedge on the Company'sParent's $175.0 million subordinated debentures issued on June 16, 2016, the Company is paying a floating rate of three-month LIBOR plus 3.25% and is receiving quarterly fixed payments of 6.25% to match the payments on the debt.

Derivatives Not Designated in Hedge Relationships

Management also enters into certain foreign exchange derivative contracts and back-to-back interest rate swaps which are not designated as accounting hedges. Foreign exchange derivative contracts include spot, forward, forward window, and swap contracts. The purpose of these derivative contracts is to mitigate foreign currency risk on transactions entered into, or on behalf of customers. Contracts with customers, along with the related derivative trades that the Company places, are both remeasured at fair value, and are referred to as economic hedges since they economically offset the Company's exposure. The Company's back-to-back interest rate swaps are used to manage long-term interest rate risk.

Fair Value Hedges

As of September 30, 2020 and December 31, 2019, the following amounts are reflected on the Consolidated Balance Sheets related to cumulative basis adjustments for fair value hedges:

Fair Values, Volume of Activity, and Gain/Loss Information Related to Derivative Instruments
The following table summarizes the fair values of the Company's derivative instruments on a gross and net basis as of September 30, 2017,2020, December 31, 2016,2019, and September 30, 2016.2019. The change in the notional amounts of these derivatives from September 30, 20162019 to September 30, 20172020 indicates the volume of the Company's derivative transaction activity during these periods. The derivative asset and liability balances are presented on a gross basis, prior to the application of bilateral collateral and master netting agreements. Total derivative assets and liabilities are adjusted to take into account the impact of legally enforceable master netting agreements that allow the Company to settle all derivative contracts with the same counterparty on a net basis and to offset the net derivative position with the related collateral. Where master netting agreements are not in effect or are not enforceable under bankruptcy laws, the Company does not adjust those derivative amounts with counterparties. The fair value of derivative contracts, after taking into account the effects of master netting agreements, is included in other assets or other liabilities inon the Consolidated Balance Sheets, as indicated in the following table:

Counterparty Credit Risk
Like other financial instruments, derivatives contain an element of credit risk. This risk is measured as the expected positive replacement value of the contracts. Management generally enters into bilateral collateral and master netting agreements that provide for the net settlement of all contracts with the same counterparty. Additionally, management monitors counterparty credit risk exposure on each contract to determine appropriate limits on the Company's total credit exposure across all product types.types, which may require the Company to post collateral to counterparties when these contracts are in a net liability position and conversely, for counterparties to post collateral to the Company when these contracts are in a net asset position. In general, the Company has a zero credit threshold with regard to derivative exposure with counterparties. Management reviews the Company's collateral positions on a daily basis and exchanges collateral with counterparties in accordance with standard ISDA documentation and other related agreements. The Company generally posts or holds collateral in the form of cash deposits or highly rated securities issued by the U.S. Treasury or government-sponsored enterprises, such as GNMA, FNMA, and FHLMC. The total collateral netted againstpledged by the Company to counterparties exceeded its net derivative liabilities totaled $59.3 million atas of September 30, 2017, $65.7 million at2020, December 31, 2016,2019, and $100.1 million at September 30, 2016.2019, resulting in excess collateral postings of $14.6 million, $29.2 million and $31.0 million, respectively.

Credit Risk Contingent Features
Management has entered into certain derivative contracts that require the Company to post collateral to the counterparties when these contracts are in a net liability position. Conversely, the counterparties may be required to post collateral when these contracts are in a net asset position. The amount of collateral to be posted is based on the amount of the net liability and exposure thresholds. As of September 30, 2017, December 31, 2016, and September 30, 2016 the aggregate fair value of all derivative contracts with credit risk contingent features (i.e., those containing collateral posting provisions) held by the Company that were in a net liability position totaled $57.8 million, $63.9 million, and $100.1 million, respectively. As of September 30, 2017, the Company was in an over-collateralized net position of $25.1 million after considering $84.4 million of collateral held in the form of cash and securities. As of December 31, 2016 and September 30, 2016, the Company was in an over-collateralized position of $24.3 million and $23.1 million, respectively.

10. INCOME TAXES
The Company's effective tax rate was 29.64%18.50% and 30.32%18.30% for the three months ended September 30, 20172020 and 2016,2019, respectively. For the nine months ended September 30, 20172020 and 2016,2019, the Company's effective tax rate was 27.89%18.05% and 28.31%17.52%, respectively. The increase in the effective tax rate from the three and nine months ended September 30, 2019 is due primarily to tax expense associated with a surrender of bank owned life insurance, detriments from vested stock compensation and increased state tax accruals, partially offset by increases in forecasted tax-exempt income and investment tax credits in 2020.
As of September 30, 2017,2020, the net deferred tax asset was $83.8$46.6 million, a decreasean increase of $11.4$28.6 million from December 31, 2016.2019. This overall decreaseincrease in the net deferred tax asset was primarily the result of increasesan increase in the fair market value ofallowance for credit losses under the new CECL accounting guidance, which upon adoption on January 1, 2020, increased the deferred tax asset by $8.7 million. Expected tax credit carryovers which were not fully offset by additional unrealized gains on AFS securities andalso contributed to the overall increase in accrued deferred loan costs.increase. For a detailed discussion of the impact of adoption of CECL, see "Note 1. Summary of Significant Accounting Policies."
Although realization is not assured, the Company believes that the realization of the recognized deferred tax asset of $83.8$46.6 million at September 30, 20172020 is more-likely-than-not based on expectations as to future taxable income and based on available tax planning strategies within the meaning of ASC 740, Income Taxes, that could be implemented if necessary to prevent a carryover from expiring.
At September 30, 20172020 and December 31, 2016,2019, the Company had no0 deferred tax valuation allowance.
TheAs of September 30, 2020, the Company’s gross federal NOL carryovers after current year-to-date utilization, all of which are subject to limitations under Section 382 of the IRC, totaled approximately $44.6 million for which a deferred tax asset related toof $5.2 million has been recorded, reflecting the expected benefit of these remaining federal andNOL carryovers. The Company also has varying gross amounts of state NOL carryovers, outstanding at eachwith the most significant in Arizona. The gross Arizona NOL carryovers totaled approximately $0.7 million. A deferred tax asset balance of the periods ended$0.1 million as of September 30, 20172020 has been recorded to reflect the expected benefit of all remaining state NOL carryovers.
LIHTC and December 31, 2016 available to reduce the tax liability in future years totaled $8.8 million and $9.0 million, respectively. These tax benefits relate entirely to federal NOL carryovers (subject to an annual limitation imposed by IRC Section 382). The Company’s ability to use federal NOL carryovers, as well as its ability to use certain future tax deductions called NUBILs associated with the Company's acquisitions is subject to annual limitations. In management’s opinion, it is more-likely-than-not that the results of future operations will generate sufficient taxable income to realize all of the deferred tax benefits related to these NOL carryovers and NUBILs.
Investments in LIHTCrenewable energy projects
The Company investsholds ownership interests in LIHTC fundslimited partnerships and limited liability companies that invest in affordable housing and renewable energy projects. These investments are designed to generate a return primarily through the realization of federal tax credits.credits and deductions. The limited liability entities are considered to be VIEs; however, as a limited partner, the Company is not the primary beneficiary and is not required to consolidate these entities.
Investments in LIHTC and unfundedrenewable energy total $414.3 million and $409.4 million as of September 30, 2020 and December 31, 2019, respectively. Unfunded LIHTC and renewable energy obligations are included as part of other assets and other liabilities respectively, inon the Consolidated Balance Sheets and total $252.9$161.5 million and $149.4$191.0 million respectively, as of September 30, 2017, compared to $187.4 million2020 and $84.4 million as of December 31, 2016.2019, respectively. For the three months ended September 30, 20172020 and 2016, $6.82019, $14.5 million and $5.5$13.0 million, respectively, of amortization related to LIHTC investments was recognized as a component of income tax expense. For the nine months ended September 30, 20172020 and 2016, $19.52019, $34.2 million and $13.7$33.6 million, respectively, of amortization related to LIHTC investments was recognized as a component of income tax expense, respectively.expense.
12.11. COMMITMENTS AND CONTINGENCIES
Unfunded Commitments and Letters of Credit
The Company is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. They involve, to varying degrees, elements of credit risk in excess of amounts recognized inon the Consolidated Balance Sheets.
Lines of credit are obligations to lend money to a borrower. Credit risk arises when the borrower's current financial condition may indicate less ability to pay than when the commitment was originally made. In the case of standby letters of credit, the risk arises from the potential failure of the customer to perform according to the terms of a contract. In such a situation, the third party might draw on the standby letter of credit to pay for completion of the contract and the Company would look to its customer to repay these funds with interest. To minimize the risk, the Company uses the same credit policies in making commitments and conditional obligations as it would for a loan to that customer.
Standby lettersLetters of credit and financial guarantees are commitments issued by the Company to guarantee the performance of a customer to a third party in borrowing arrangements. The Company generally has recourse to recover from the customer any amounts paid under the guarantees. Typically, letters of credit issued have expiration dates within one year.

Commitments to extend credit are agreements to lend to a customer provided that there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The Company enters into credit arrangements that generally provide for the termination of advances in the event of a covenant violation or other event of default. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the party. The commitments are collateralized by the same types of assets used as loan collateral.
The Company has exposure to credit losses from unfunded commitments and letters of credit. As funds have not been disbursed on these commitments, they are not reported as loans outstanding. Credit losses related to these commitments are included in other liabilities as a separate loss contingency and are not included in the allowance for credit losses reported in "Note 3. Loans, Leases and Allowance for Credit Losses" of these Unaudited Consolidated Financial Statements. This loss contingency for unfunded loan commitments and letters of credit was $5.6$44.4 millionand $7.0$9.0 million as of September 30, 20172020 and December 31, 2016,2019, respectively. Changes to this liability are adjusted through non-interest expense.the provision for credit losses in the Consolidated Income Statement. In addition, upon adoption of ASU 2016-13 on January 1, 2020, the Company recorded an increase of $15.1 million to this liability, which was recorded as an adjustment to retained earnings, net of tax.
Concentrations of Lending Activities
The Company’s lending activities are driven in large part by the customers served in the market areas where the Company has branch offices in the states of Arizona, Nevada, and California. Despite the geographic concentration of lending activities, the Company does not have a single external customer from which it derives 10% or more of its revenues. The Company monitors concentrations within four broad categories: geography, industry, product, and collateral. The Company's loan portfolio includes significant credit exposure to the CRE market. As of each of the periods ended September 30, 20172020 and December 31, 2016,2019, CRE related loans accounted for approximately 51%38% and 53%45% of total loans, respectively. Substantially all of these loans are secured by first liens with an initial loan to valueloan-to-value ratio of generally not more than 75%. Approximately 36%29% and 31% of these CRE loans, excluding construction and land loans, were owner-occupied at each of the periods ended September 30, 20172020 and December 31, 2016.2019, respectively.
Contingencies
The Company is involved in various lawsuits of a routine nature that are being handled and defended in the ordinary course of the Company’s business. Expenses are being incurred in connection with these lawsuits, but in the opinion of management, based in part on consultation with outside legal counsel, the resolution of these lawsuits and associated defense costs will not have a material impact on the Company’s financial position, results of operations, or cash flows.
Lease Commitments
The Company has operating leases the majority ofunder which it leases its office locationsbranch offices, corporate headquarters, other offices, and many of these leases contain multiple renewal optionsdata facility centers. Operating lease costs totaled $3.9 million and provisions for increased rents. Total rent expense of $2.8$10.9 million for each ofduring the three months ended September 30, 2017 and 2016 was included in occupancy expense. For the nine months ended September 30, 2017 and 2016, total rent expense was $8.22020, respectively, compared to $3.2 million and $8.1$9.5 million for the three and nine months ended September 30, 2019, respectively. Other lease costs, which include common area maintenance, parking, and taxes, and were included as part of occupancy expense, totaled $1.0 million and $2.9 million during the three and nine months ended September 30, 2020, respectively, compared to $1.0 million and $3.0 million for the three and nine months ended September 30, 2019, respectively.

12. FAIR VALUE ACCOUNTING
The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach, and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC 825 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under ASC 825 are described in "Note 1. Summary of Significant Accounting Policies" of these Notes to Unaudited Consolidated Financial Statements.
In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developedinternally-developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Company’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Furthermore, the reported fair value amounts have not been comprehensively revalued since the presentation dates, and therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein. A more detailed description of the valuation methodologies used for assets and liabilities measured at fair value is set forth below. Transfers between levels in the fair value hierarchy are recognized as of the end of the month following the event or change in circumstances that caused the transfer.
Under ASC 825, the Company elected the FVO treatment for junior subordinated debt heldissued by WAL. This election is irrevocable and results in the recognition of unrealized gains and losses on these items at each reporting date. Due to the Company's election to early adopt an element of ASU 2016-01, effective January 1, 2015, theseThese unrealized gains and losses are recognized as part of other comprehensive income rather than earnings. The Company did not elect FVO treatment for the junior subordinated debt assumed in the Bridge Capital Holdings acquisition in 2015.
All securities for which the fair value measurement option had been elected are included in a separate line item in the Consolidated Balance Sheets as securities measured at fair value. During the nine months ended September 30, 2017, the Company sold all of its investment securities measured at fair value. No significant gain or loss was recognized upon sale of these securities.

Fair value on a recurring basis
Financial assets and financial liabilities measured at fair value on a recurring basis include the following:
Securities measured at fair value: All of the Company’s securities measured at fair value, which consist of MBS, are reported at fair value utilizing Level 2 inputs in the same manner as described below for AFS securities.
AFS securities: Preferred stock, CRA investments, and certain corporate debt securities Securities classified as AFS are reported at fair value utilizing Level 1 inputs. Other securities classified as AFS are reported at fair value utilizingand Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include quoted prices in active markets, dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the bond’s terms and conditions, among other things.
Historically, the Company has estimated theEquity securities: Preferred stock and CRA investments are reported at fair value of its CDO securitiesprimarily utilizing Level 3 inputs, which include pricing indications from comparable securities. During the year ended December 31, 2016, these securities were transferred from Level 3 to Level 2 as a result of an increase in the availability and reliability of the observable inputs utilized in the securities' fair value measurement.1 inputs.
Independent pricing service: The Company's independent pricing service provides pricing information on the majority of the Company's Level 1 and Level 2 AFS securities. For a small subset of securities, other pricing sources are used, including observed prices on publicly traded securities and dealer quotes. Management independently evaluates the fair value measurements received from the Company's third partythird-party pricing service through multiple review steps. First, management reviews what has transpired in the marketplace with respect to interest rates, credit spreads, volatility, and mortgage rates, among other things, and develops an expectation of changes to the securities' valuations from the previous quarter. Then, management obtainsselects a sample of investment securities and compares the values provided by its primary third-party pricing service to the market values obtained from additional sources.

Any remaining discrepancies between management’s review and the prices provided by the vendor are discussed with the vendor andand/or the Company’s other valuation advisors. Lastly, management selects a sample of investment securities and compares the values provided by its primary third party pricing service to the market values obtained from secondary sources and evaluates those with notable variances.
Interest rate swaps: Interest rate swaps are reported at fair value utilizing Level 2 inputs. The Company obtains dealer quotations to value its interest rate swaps.
Junior subordinated debt: The Company estimates the fair value of its junior subordinated debt using a discounted cash flow model which incorporates the effect of the Company’s own credit risk in the fair value of the liabilities (Level 3). The Company’s cash flow assumptions are based on contractual cash flows as the Company anticipates that it will pay the debt according to its contractual terms.
As of September 30, 2017, the Company estimates the discount rate at 5.42%, which represents an implied credit spread of 4.09% plus three-month LIBOR (1.33%). As of December 31, 2016, the Company estimated the discount rate at 5.66%, which was a 4.66% credit spread plus three-month LIBOR (1.00%).

Impaired loans:Loans: Loans measured at fair value on a nonrecurring basis include collateral dependent loans held for investment. The specific reserves for collateral dependent impairedthese loans are based on collateral value, net of estimated disposition costs and other identified quantitative inputs. Collateral value is determined based on independent third-party appraisals or internally-developed discounted cash flow analyses. Appraisals may utilize a single valuation approach or a combination of approaches, including comparable sales and the income approach. Fair value is determined, where possible, using market prices derived from an appraisal or evaluation, which are considered to be Level 2. However, certain assumptions and unobservable inputs are often used by the appraiser, therefore qualifying the assets as Level 3 in the fair value hierarchy. In addition, when adjustments are made to an appraised value to reflect various factors such as the age of the appraisal or known changes in the market or the collateral, such valuation inputs are considered unobservable and the fair value measurement is categorized as a Level 3 measurement. Internal discounted cash flow analyses are also utilized to estimate the fair value of impairedthese loans, which considers internally-developed, unobservable inputs such as discount rates, default rates, and loss severity.
Total Level 3 impairedcollateral dependent loans had an estimated fair value of $74.5$245.2 million and $67.4$110.3 million at September 30, 20172020 and December 31, 2016, respectively. Impaired loans with a specific valuation allowance had a gross estimated fair value2019, respectively, net of $8.8 million and $10.9 million at September 30, 2017 and December 31, 2016, respectively, which was reduced by a specific valuation allowance of $4.4$9.6 million and $4.2$2.8 million at September 30, 2020 and December 31, 2019, respectively.

Other assets acquired through foreclosure: Other assets acquired through foreclosure consist of properties acquired as a result of, or in-lieu-of, foreclosure. These assets are initially reported at the fair value determined by independent appraisals using appraised value less estimated cost to sell. Such properties are generally re-appraised every twelve months. There is risk for subsequent volatility. Costs relating to the development or improvement of the assets are capitalized and costs relating to holding the assets are charged to expense.
Fair value is determined, where possible, using market prices derived from an appraisal or evaluation, which are considered to be Level 2. However, certain assumptions and unobservable inputs are often used by the appraiser, therefore qualifying the assets as Level 3 in the fair value hierarchy. When significant adjustments are based on unobservable inputs, such as when a current appraised value is not available or management determines the fair value of the collateral is further impaired below the

appraised value and there is no observable market price, the resulting fair value measurement has been categorized as a Level 3 measurement. The Company had $29.0$8.6 million and $47.8$13.9 million of such assets at September 30, 20172020 and December 31, 2016,2019, respectively.
Credit vs. non-credit losses
Under the provisionsFair Value of ASC 320, Investments-Debt and Equity Securities, OTTI is separated into the amount of total impairment related to the credit loss and the amount of the total impairment related to all other factors. The amount of the total OTTI related to the credit loss is recognized in earnings. The amount of the total impairment related to all other factors is recognized in OCI.
For the three and nine months ended September 30, 2017 and 2016, the Company determined that no securities experienced credit losses.
There is no OTTI balance recognized in comprehensive income as of September 30, 2017 and 2016.

Interest rate risk
The Company assumes interest rate risk (the risk to the Company’s earnings and capital from changes in interest rate levels) as a result of its normal operations. As a result, the fair values of the Company’s financial instruments, as well as its future net interest income, will change when interest rate levels change and that change may be either favorable or unfavorable to the Company.
Interest rate risk exposure is measured using interest rate sensitivity analysis to determine the Company's change in EVE and net interest income resulting from hypothetical changes in interest rates. If potential changes to EVE and net interest income resulting from hypothetical interest rate changes are not within the limits established by the BOD, the BOD may direct management to adjust the asset and liability mix to bring interest rate risk within BOD-approved limits.
WAB has an ALCO charged with managing interest rate risk within the BOD-approved limits. Limits are structured to prohibitpreclude an interest rate risk profile that does not conform to both management and BOD risk tolerances.tolerances without ALCO approval. There is also ALCO reporting at the Parent level for reviewing interest rate risk for the Company, which gets reported to the BOD and its Finance and Investment Committee.
Fair value of commitments
The estimated fair value of standby letters of credit outstanding at September 30, 20172020 and December 31, 2016 is insignificant.2019 approximates zero as there have been no significant changes in borrower creditworthiness. Loan commitments on which the committed interest rates are less than the current market rate are also insignificant at September 30, 20172020 and December 31, 2016.2019.

13. SEGMENTS
The Company's reportable segments are aggregated based primarily on geographic location, services offered, and markets served. The Company's regional segments, which include Arizona, Nevada, Southern California, and Northern California, provide full service banking and related services to their respective markets. The operations from the regional segments correspond to the following banking divisions: ABA in Arizona, BON and FIB in Nevada, TPB in Southern California, and Bridge in Northern California.
The Company's NBL segments provide specialized banking services to niche markets. The Company's NBL reportable segments include HOA Services, Public & Nonprofit Finance, Technology & Innovation, HFF, and Other NBLs. These NBLs are managed centrally and are broader in geographic scope than the Company's other segments, though still predominately located within the Company's core market areas. The HOA Services NBL corresponds to the AAB division. The operations of Public and Nonprofit Finance are combined into one reportable segment. The Technology & Innovation NBL includes the operations of Equity Fund Resources, Life Sciences Group, Renewable Resource Group, and Technology Finance. The HFF NBL includes the hotel franchise loan portfolio acquired from GE Capital US Holdings, Inc. on April 20, 2016. The Other NBLs segment consists of Corporate Finance, Mortgage Warehouse Lending, and Resort Finance.
The Corporate & Other segment consists of corporate-related items, income and expense items not allocated to the Company's other reportable segments, and inter-segment eliminations.
The Company's segment reporting process begins with the assignment of all loan and deposit accounts directly to the segments where these products are originated and/or serviced. Equity capital is assigned to each segment based on the risk profile of their assets and liabilities. With the exception of goodwill, which is assigned a 100% weighting, equity capital allocations ranged from 0% to 12% during the year, with a funds credit provided for the use of this equity as a funding source. Any excess or deficient equity not allocated to segments based on risk is assigned to the Corporate & Other segment.
Net interest income, provision for credit losses, and non-interest expense amounts are recorded in their respective segment to the extent that the amounts are directly attributable to those segments. Net interest income is recorded in each segment on a TEB with a corresponding increase in income tax expense, which is eliminated in the Corporate & Other segment.
Further, net interest income of a reportable segment includes a funds transfer pricing process that matches assets and liabilities with similar interest rate sensitivity and maturity characteristics. Using this funds transfer pricing methodology, liquidity is transferred between users and providers. A net user of funds has lending/investing in excess of deposits/borrowings and a net provider of funds has deposits/borrowings in excess of lending/investing. A segment that is a user of funds is charged for the use of funds, while a provider of funds is credited through funds transfer pricing, which is determined based on the average life of the assets or liabilities in the portfolio. Residual funds transfer pricing mismatches are allocable to the Corporate & Other segment and presented as part of net interest income.
The net income amount for each reportable segment is further derived by the use of expense allocations. Certain expenses not directly attributable to a specific segment are allocated across all segments based on key metrics, such as number of employees, average loan balances, and average deposit balances. These types of expenses include information technology, operations, human resources, finance, risk management, credit administration, legal, and marketing.
Income taxes are applied to each segment based on the effective tax rate for the geographic location of the segment. Any difference in the corporate tax rate and the aggregate effective tax rates in the segments are adjusted in the Corporate & Other segment.

Performance Obligations
Many of the services the Company engagesperforms for its customers are ongoing, and either party may cancel at any time. The fees for these contracts are dependent upon various underlying factors, such as customer deposit balances, and as such may be considered variable. The Company’s performance obligations for these services are satisfied as the services are rendered and payment is collected on a monthly, quarterly, or semi-annual basis. Other contracts with customers are for services to be provided at a point in various related party transactions, including extending credittime, and bank service transactions. All related party transactionsfees are subject to reviewrecognized at the time such services are rendered. The Company had no material unsatisfied performance obligations as of September 30, 2020. The revenue streams within the scope of ASC 606 are described in further detail below.
Service Charges and approval pursuantFees
The Company performs deposit account services for its customers, which include analysis and treasury management services, use of safe deposit boxes, check upcharges, and other ancillary services. The depository arrangements the Company holds with its customers are considered day-to-day contracts with ongoing renewals and optional purchases, and as such, the contract duration does not extend beyond the services performed. Due to the Company's Related Party Transactions policy.
On April 1, 2017,short-term nature of such contracts, the Company hired an executive officer who was previously the Managing Partner of an external consulting firm thatgenerally recognizes revenue for deposit related fees as services are rendered. From time to time, the Company actively usesmay waive certain fees for risk management services. Priorits customers. The Company considers historical experience when recognizing revenue from contracts with customers, and may reduce the transaction price to joiningaccount for fee waivers or refunds.
Debit and Credit Card Interchange
When a credit or debit card issued by the Company is used to purchase goods or services from a merchant, the executive officer sold his interestCompany earns an interchange fee. The Company considers the merchant its customer in this external consulting firmthese transactions as the Company provides the merchant with the service of enabling the cardholder to purchase the merchant’s goods or services with increased convenience, and was paidit enables the merchants to transact with a combinationclass of customer that may not have access to sufficient funds at the time of purchase. The Company acts as an agent to the payment network by providing nightly settlement services between the network and the merchant. This transmission of data and funds represents the Company’s performance obligation and is performed nightly. As the payment network is in direct control of setting the rates and the Company is acting as an agent, the interchange fee is recorded net of expenses as the services are provided.
Success Fees
Success fees are one-time fees detailed as part of certain loan agreements and are earned immediately upon occurrence of a triggering event. Examples of triggering events include: a borrower obtaining its next round of funding, an acquisition, or completion of a public offering. Success fees are variable consideration as the transaction price can vary and is contingent on the occurrence or non-occurrence of a future event. As the consideration is highly susceptible to factors outside of the Company’s influence and uncertainty about the amount of consideration is not expected to be resolved for an extended period of time, the variable consideration is constrained and is not recognized until the achievement of the triggering event.
Principal versus Agent Considerations
When more than one party is involved in providing goods or services to a customer, ASC 606 requires the Company to determine whether it is the principal or an agent in these transactions by evaluating the nature of its promise to the customer. An entity is a principal and therefore records revenue on a gross basis, if it controls a promised good or service before transferring that good or service to the customer. An entity is an agent and records as revenue the net amount it retains for its agency services if its role is to arrange for another entity to provide the goods or services. The Company most commonly acts as a principal and records revenue on a gross basis, except in certain circumstances. As an example, revenues earned from interchange fees, in which the Company acts as an agent, are recorded as non-interest income, net of the related expenses paid to the principal.
Contract Balances
The timing of revenue recognition may differ from the timing of cash and a $1.0 million note that will be paidsettlements or invoicing to customers. The Company records contract liabilities, or deferred revenue, when payments from customers are received or due in equal installments ending in 2019. Expenses to this external consulting firm as well as sponsorships, donations and otheradvance of providing services to related parties totaled less than $3.0customers. The Company generally receives payments for its services during the period or at the time services are provided, therefore, does not have material contract liability balances at period-end. The Company records contract assets or receivables when revenue is recognized prior to receipt of cash from the customer. Accounts receivable totals $1.5 million duringand $1.6 million at each of the nine monthsperiods ended September 30, 20172020 and 2016.December 31, 2019, respectively, and are presented in Other assets on the Consolidated Balance Sheets.

Recent Developments: COVID-19 and the CARES Act
The ongoing COVID-19 global and national health emergency has caused significant disruption in the United States and international economies and financial markets. The spread of COVID-19 in the United States has caused illness, quarantines, cancellation of events and travel, business and school shutdowns, reduction in commercial activity and financial transactions, supply chain interruptions, increased unemployment, and overall economic and financial market instability. Many states, including Arizona, where we are headquartered, and California and Nevada, in which we have significant operations, declared states of emergency. These states, like many others, continue to be significantly impacted by the pandemic.
In response to the COVID-19 pandemic, the CARES Act was signed into law by President Trump on March 27, 2020. The CARES Act provides for approximately $2.2 trillion in emergency economic relief measures including, among other things, loan programs for small and mid-sized businesses and other economic relief for impacted businesses and industries, including financial institutions. Separately, and also in response to COVID-19, the Federal Reserve’s FOMC has set the federal funds target rate - i.e., the interest rate at which depository institutions such as the Bank lend reserve balances to other depository institutions overnight on an uncollateralized basis - to a historic low. On March 16, 2020, the FOMC set the federal funds target rate at 0 to 0.25 percent.
In addition to the general impact of the COVID-19 pandemic, certain provisions of the CARES Act and other recent legislative and regulatory relief efforts are expected to have a material impact on our operations, which are further discussed below.
Financial position and results of operations
The Company's financial position and results of operations as of and for the three and nine months ended September 30, 2020 have been significantly impacted by the COVID-19 pandemic. The worsening of forecasted economic conditions from December 31, 2019 to September 30, 2020 attributable to the pandemic contributed to the $14.7 million and $157.8 million provision for credit losses recognized during the three and nine months ended September 30, 2020, respectively, under the new CECL accounting standard adopted by the Company on January 1, 2020. While the Company has not to date experienced significant writeoffs related to the COVID-19 pandemic, the continued uncertainty regarding the severity and duration of the pandemic and related economic effects will continue to affect the Company’s estimate of its allowance for credit losses and resulting provision for credit losses. To the extent the impact of the pandemic is prolonged and economic conditions continue to worsen or persist longer than forecast, such estimates may be insufficient and may change significantly in the future. The Company’s interest income also may be negatively impacted in future periods as we continue to work with our affected borrowers to defer payments, interest and fees. Additionally, net interest margin may be reduced generally as a result of the low rate environment. These uncertainties and the economic environment will continue to affect earnings, slow growth, and may result in deterioration of asset quality in the Company's loan and investment portfolios. 
The below table details the Company's exposure to borrowers in industries generally considered to be the most impacted by the COVID-19 pandemic:
September 30, 2020

Lending operations and accommodations to borrowers
The CARES Act created a new guaranteed, unsecured loan program under the SBA, called the Payroll Protection Program, or the PPP, which the Bank participates in, to fund operational costs of eligible businesses, organizations and self-employed persons during the pandemic period. The SBA has used funds authorized for the PPP to guarantee 100% of the amounts loaned under the PPP by lenders to eligible small businesses, nonprofits, veterans' organizations, and tribal businesses. One of the notable features of the PPP is that borrowers are eligible for loan forgiveness if borrowers maintain their staff and payroll and if loan amounts are used to cover eligible expenses, such as payroll, mortgage interest, rents and utilities payments. These loans have a two-year term and will earn interest at a rate of 1%. The Company assisted our customers with applications for resources through the program and approved over 4,700 applications. As of September 30, 2020, the outstanding balance of loans originated under the PPP totaled $1.7 billion.
The CARES Act permits financial institutions to suspend requirements under GAAP for loan modifications to borrowers affected by COVID-19 and is intended to provide interpretive guidance as to conditions that would constitute a short-term modification that would not meet the definition of a TDR. This includes the following (i) the loan modification is made between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the end of the coronavirus emergency declaration, and (ii) the applicable loan was not more than 30 days past due as of December 31, 2019. The Company is applying this guidance to qualifying loan modifications. As of September 30, 2020, the Company has outstanding modifications meeting these conditions on loans with a net balance of $1.5 billion as of September 30, 2020. Further, residential mortgage loans in forbearance have a net balance of $127.3 million as of September 30, 2020.
The MSLP supports lending to small and medium-sized businesses that were in sound financial condition before the onset of the COVID-19 pandemic. The MSLP operates through five facilities: the Main Street New Loan Facility, the Main Street Priority Loan Facility, the Main Street Expanded Loan Facility, the Nonprofit Organization New Loan Facility, and the Nonprofit Organization Expanded Loan Facility. The Federal Reserve Bank of Boston maintains the legal forms and agreements for eligible borrowers and eligible lenders to participate in the MSLP, and continues to refine the MSLP’s operational infrastructure and facilities. The Bank has registered as a lender under the MSLP and continues to monitor developments related thereto.
Capital and liquidity
While the Company has sufficient capital and does not anticipate any need for additional liquidity in response to the uncertainty regarding the severity and duration of the COVID-19 pandemic, the Company has taken several actions to ensure the strength of its capital and liquidity position. These actions include issuance of $225 million in subordinated debt at our bank subsidiary in May 2020, establishing a Federal Reserve lending facility in connection with funding loans to small and medium-sized businesses, and temporarily suspending stock repurchases since mid-April. In addition, the Company is also in a position to pledge additional collateral to increase its borrowing capacity with the FRB, if necessary. Further, management has elected to take advantage of the capital relief option that delays the estimated impact on regulatory capital by up to two years, with a three-year transition period to phase out the cumulative benefit to regulatory capital provided during the two-year delay.
Asset valuation
While the Company’s stock price has experienced volatility and periodic declines in value during the pandemic, management does not consider this decline to be a triggering event that would indicate that an interim goodwill impairment test was necessary as of September 30, 2020. Continued and sustained declines in the Company's stock price and/or other credit related impacts could give rise to triggering events in the future that could result in a write-down in the value of our goodwill, which could have a material adverse impact on our results of operations.

Our processes, controls and business continuity plan
The Company has focused first on ensuring the well-being of our people, customers, and communities. Preventive health measures were put in place, which included establishing social distancing precautions for all employees in the office and customers visiting branches, preventive cleaning at offices and branches, and elimination of business related travel. The Company has continued returning employees to the office subject to applicable health and safety procedures in accordance with guidance from the CDC and local authorities, including regular symptom checks, requiring face cloth coverings, increasing physical space between employees, monitoring the number of employees in the workplace, and requiring employees with COVID-19 related symptoms or exposure to quarantine away from the office.
The Company has also concentrated on implementing additional business continuity measures that include establishing a cross-functional COVID-19 team, monitoring potential business interruptions, making improvements to our remote working technology, and conducting regular discussions with our technology vendors. We have not experienced significant disruption to our business as we have been able to facilitate remote work for our employees and have online tools in place for our customers. We believe that we are positioned to continue these business continuity measures for the foreseeable future; however, no assurances can be provided as these circumstances may change depending on the duration of the pandemic.
Included at the end of this section are updates to the Supervision and Regulation discussion disclosed in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations," in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2019.

Non-GAAP Financial Measures
The following discussion and analysis contains financial information determined by methods other than those prescribed by GAAP. The Company's management uses these non-GAAP financial measures in their analysis of the Company's performance. These measurements typically adjust GAAP performance measures to exclude the effects of certain significant activities or transactions that, in management's opinion, do not reflect recurring period-to-period comparisons of the Company's performance. Management believes presentation of these non-GAAP financial measures provides useful supplemental information that is essential to a complete understanding of the operating results of the Company's core businesses.Company. Since the presentation of these non-GAAP performance measures and their impact differ between companies, these non-GAAP disclosures should not be viewed as a substitute for operating results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies.
Operating Pre-Provision Net Revenue
Operating PPNR is defined by the Federal Reserve in SR 14-3, which requires companies subject to the rule to project PPNR over the planning horizon for each of the economic scenarios defined annually by the regulators. Banking regulations define PPNR as net interest income plus non-interest income less non-interest expense. Management has further adjusted this metric to exclude any non-recurring or non-operational elements of non-interest income or non-interest expense, which are outlined in the table below. Management feelsbelieves that this is an important metric as it illustrates the underlying performance of the Company, it enables investors and others to assess the Company's ability to generate capital to cover credit losses through the credit cycle, and provides consistent reporting with a key metric used by bank regulatory agencies.

Tangible Common Equity
The following table presents financial measures related to tangible common equity. Tangible common equity represents total stockholders' equity, less identifiable intangible assets and goodwill. Management believes that tangible common equity financial measures are useful in evaluating the Company's capital strength, financial condition, and ability to manage potential losses. In addition, management believes that these measures improve comparability to other institutions that have not engaged in acquisitions that resulted in recorded goodwill and other intangible assets.

Regulatory Capital
The following table presents certain financial measures related to regulatory capital under Basel III, which includes Common Equity Tiercommon equity tier 1 and total capital. The FRB and other banking regulators use Common Equity Tiercommon equity tier 1 and total capital as a basis for assessing a bank's capital adequacy; therefore, management believes it is useful to assess financial condition and capital adequacy using this same basis. Specifically, the total capital ratio takes into consideration the risk levels of assets and off-balance sheet financial instruments. In addition, management believes that the classified assets to Common Equity Tiercommon equity tier 1 plus allowance measure is an important regulatory metric for assessing asset quality.
As permitted by the regulatory capital rules, the Company elected to delay the estimated impact of CECL on its regulatory capital over a five-year transition period ending December 31, 2024. As a result, capital ratios and amounts as of September 30, 2020 exclude the impact of the increased allowance for credit losses related to the adoption of ASC 326.

Comparison of interest income, interest expense and net interest margin
The Company's primary source of revenue is interest income. For the three months ended September 30, 2017,2020, interest income was $217.8$304.8 million, an increasea decrease of $33.1$10.8 million, or 17.9%3.4%, compared to $184.8$315.6 million for the three months ended September 30, 2016.2019. This decrease was primarily the result of a decrease in other interest income from interest bearing cash accounts and federal funds sold of $6.2 million. Also contributing to the decrease in total interest income were net declines in interest income from loans and investment securities, each totaling $2.3 million. The decline in interest rates from September 30, 2019 outweighed the increases in the related average asset balances, resulting in a decrease in total interest income.
For the nine months ended September 30, 2020, interest income was $930.3 million, an increase of $20.7 million, or 2.3%, compared to $909.6 million for the nine months ended September 30, 2019. This increase was primarily the result of a $1.17$5.1 billion increase in the average loan balance, which together withoffset the effect of the rising rate environment, drove a $23.2 million increase in loan interest income for the three months ended September 30, 2017. Interest income from investment securities increased by $8.1 million for the comparable period primarily due to an increase in the average investment balance of $1.03 billion from September 30, 2016 as well as an increasedecline in interest rates and mix.

The increase in net interest income reflects a $6.7 billion increase in average interest-earning assets, partially offset by an increase of $2.7 billion in average interest-bearing liabilities. The decrease in net interest margin of 70 basis points to 3.71% is largely the result of excess liquidity from deposit growth that has outpaced loan growth as well as a decrease in loan yields due to a lower rate environment and lower yields on PPP loans primarily driven by changes in prepayment assumptions that reduced net deferred loan fee accretion on PPP loans during the three months ended September 30, 2020. These decreases to net interest margin were offset by lower deposit and funding costs for the three months ended September 30, 2020 compared to the same period in 2016. The increase is attributable to an increase in the Company's interest payments on its pay variable/receive fixed interest rate swaps. These swaps hedge the Company's subordinated debt offerings and the payments are tied to three-month LIBOR, which has increased since September 30, 2016.2019.

Interest expense on qualifying debt increased by $4.8 million as a result of a $105.1 million increase in average qualifying debt for the nine months ended September 30, 2017 compared to the same period in 2016, as well as an increase in the Company's interest payments on its pay variable/receive fixed interest rate swaps.
For the three months ended September 30, 2017, net interest income was $201.6 million, compared to $172.5 million for the three months ended September 30, 2016.2019. The increase in net interest income reflects a $2.36$5.9 billion increase in average interest-earning assets, partially offset by a $290.8 millionan increase of $2.7 billion in average interest-bearing liabilities. The increasedecrease in net interest margin of 1053 basis points to 4.03% is the result of an increase in average yield on loansexcess liquidity and securities due to the rising interesta lower rate environment partially offset by higher deposit and funding costs.
Foras explained in the nine months ended September 30, 2017, net interest income was $573.6 million, compared to $481.9 million for the nine months ended September 30, 2016. The increase in net interest income reflects a $2.66 billion increase in average interest-earning assets, offset by a $658.4 million increase in average interest-bearing liabilities.

Provision for Credit Losses
The provision for credit losses in each period is reflected as a reduction in earnings for that period.period and, upon the adoption of CECL, includes amounts related to funded loans, unfunded loan commitments, and investment securities. The provision is equal to the amount required to maintain the allowance for credit losses at a level that is adequate to absorb probableestimated lifetime credit losses inherent in the loan portfolio.and investment securities portfolios. For the three months ended September 30, 2017, the provision for credit losses was $5.0 million compared to $2.0 million for the three months ended September 30, 2016. For the nine months ended September 30, 2017, the provision for credit losses was $12.3 million, compared to $7.0 million for the nine months ended September 30, 2016. The provision increase was primarily due to organic growth in total loans of $532.0 millionand $1.31 billion during the three and nine months ended September 30, 2017.2020, the provision for credit losses was $14.7 million and $157.8 million, compared to $3.8 million and $15.3 million for the three and nine months ended September 30, 2019, respectively. The Company defines its organicsignificant increase in the provision for credit losses from the three and nine months ended September 30, 2019 is primarily related to the current economic environment and estimating expected credit losses under the new CECL accounting standard. This standard changes the methodology for estimating credit losses on financial instruments from an incurred loss model to an expected total loss model. This results in the recognition of expected losses over the life of loans and HTM investment securities at the time that the loan is originated or the security is purchased, rather than after a loss has been incurred, which results in an acceleration in the timing of loss recognition. Further, as those loans that have not been acquiredthe Company's CECL models incorporate historical experience, current conditions, and reasonable and supportable forecasts in a transaction accounted for as a business combination. The Company may establishmeasuring expected credit losses, the worsening of economic assumptions due to the ongoing pandemic has also contributed to an additional allowanceelevated provision for credit losses for PCI loans through provision for credit losses when impairment is determined as a result of lower than expected cash flows. As ofthe nine months ended September 30, 2017 and December 31, 2016, the allowance for credit losses on PCI loans was $1.7 million and $1.8 million, respectively.2020.

The decreasemost significant increase in non-interest income relates to the net fair value gain adjustment on assets measured at fair value of $5.9 million for the three months ended September 30, 2020, compared to $0.2 million for the same period in 2019. This change is predominantly related to increases in the value of equity securities, primarily preferred stock of other financial institutions. Offsetting this increase is a decrease in the net gain on sales of investment securities and income from equity investments. During the three months ended September 30, 2019, the Company sold investment securities as part of a portfolio balancing initiative and recognized a net gain on sale of $3.2 million, which did not recur during the current period.

As mentioned above, this change is predominantly related to less than $0.1valuation declines on preferred stock investments. In addition, there was a $3.2 million forgain on security sales recognized during the nine months ended September 30, 2017.2019 that did not recur in the current period. These decreases were offset in part by an increase in income from bank owned life insurance of $6.0 million primarily attributable to a one-time enhancement fee of $5.6 million from the surrender and replacement of certain policies, which was intended to offset the increase in tax expense related to the surrender.

Impaired loans
87

Table of Contents
A loan is identified as impaired when it is no longer probable that interest and principal will be collected according to the contractual terms of the original loan agreement. Generally, impaired loans are classified as non-accrual. However, in certain instances, impaired loans may continue on an accrual basis if full repayment of all principal and interest is expected and the loan is both well-secured and in the process of collection. Impaired loans are measured for reserve requirements in accordance with ASC 310 based on the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of the collateral less applicable disposition costs if the loan is collateral dependent. The amount of an impairment reserve, if any, and any subsequent changes are charged against the allowance for credit losses.
In addition to the Company's own internal loan review process, regulators may from time to time direct the Company to modify loan grades, loan impairment calculations, or loan impairment methodology.Non-performing Assets

Based on discussions with regulatory authorities, we expect that credit rating guidelines for technology loans may involve broader parameters for classification as Special Mention, which could result in increased levels of Special Mention loans in this category than reported historically. However, such classification changes should not affect the ultimate collectability of such loans, nor result in higher levels on non-performing assets.

Capital Resources
The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements could trigger certain mandatory or discretionary actions that, if undertaken, could have a direct material effect on the Company’s business and financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off-balance sheet items (discussed in "Note 12.11. Commitments and Contingencies" to the Unaudited Consolidated Financial Statements) as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.
In March 2020, the federal bank regulatory authorities issued an interim final rule that delays the estimated impact on regulatory capital resulting from the adoption of CECL. The interim final rule provides banking organizations that implement CECL before the end of 2020 the option to delay for two years the estimated impact of CECL on regulatory capital frameworkrelative to regulatory capital determined under Basel III became effective for the prior incurred loss methodology, followed by a three-year transition period to phase out the aggregate amount of capital benefit provided during the initial two-year delay. The Company has elected the five-year CECL transition option in connection with its adoption of CECL on January 1, 2015. Under2020. As a result, capital ratios and amounts as of September 30, 2020 exclude the Basel III final rules, minimum requirements haveimpact of the increased allowance for bothcredit losses related to the quantity and qualityadoption of capital held by the Company. A new capital conservation buffer, comprised of Common Equity Tier 1 capital, is also established above the regulatory minimum capital requirements. This capital conservation buffer began being phased in on January 1, 2016 at 0.625% of risk-weighted assets and will increase each subsequent year by an additional 0.625% until reaching its final level of 2.5% on January 1, 2019. Strict eligibility requirements for regulatory capital instruments have been implemented under the final rules and the final rules also revise the definitions and calculations of Tier 1 capital, total capital, and risk-weighted assets.ASC 326.
As of September 30, 20172020 and December 31, 2016,2019, the Company and the Bank exceeded the capital levels necessary to be classified as well-capitalized, as defined by the banking agencies.

Critical Accounting Policies
Critical accounting policies are defined as those that are reflective of significant judgments and uncertainties and could potentially result in materially different results under different assumptions and conditions. The critical accounting policies upon which the Company's financial condition and results of operations depend, and which involve the most complex subjective decisions or assessments, are included in the discussion entitled "Critical Accounting Policies" in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations," in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2016,2019, and all amendments thereto, as filed with the SEC.

During the first quarter of 2020, the Company adopted the ASUs related to credit losses, which include ASU 2016-13, Measurement of Credit Losses on Financial Instruments, ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, ASU 2019-05, Financial Instruments - Credit Losses, and ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments—Credit Losses. The new standards significantly change the impairment model for most financial assets that are measured at amortized cost, including off-balance sheet credit exposures, from an incurred loss model to an expected loss model. The amendments in ASU 2016-13 require that an organization measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods, evaluations of the overall loan portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance for credit losses and credit loss expense in those future periods. The allowance level is influenced by loan volumes, loan asset quality ratings, delinquency status, historical credit loss experience, loan performance characteristics, and other conditions influencing loss expectations, such as reasonable and supportable forecasts of economic conditions. Changes to the assumptions in the model in future periods could have a material impact on the Company's Consolidated Financial Statements. See "Note 1. Summary of Significant Accounting Policies" for a detailed discussion of the Company's methodologies for estimating expected credit losses.
There were no other material changes to the critical accounting policies disclosed in the Company's Annual Report on Form 10-K.10-K for the fiscal year ended December 31, 2019.


Liquidity
Liquidity is the ongoing ability to accommodate liability maturities and deposit withdrawals, fund asset growth and business operations, and meet contractual obligations through unconstrained access to funding at reasonable market rates. Liquidity management involves forecasting funding requirements and maintaining sufficient capacity to meet the needs and accommodate fluctuations in asset and liability levels due to changes in the Company's business operations or unanticipated events.events, including the ongoing COVID-19 pandemic.
The ability to have readily available funds sufficient to repay fully maturing liabilities is of primary importance to depositors, creditors, and regulators. The Company's liquidity, represented by cash and amounts due from banks, federal funds sold, and non-pledged marketable securities, is a result of the Company's operating, investing, and financing activities and related cash flows. In order to ensure funds are available when necessary, on at least a quarterly basis, the Company projects the amount of funds that will be required over a twelve monthtwelve-month period and it also strives to maintain relationships with a diversified customer base. Liquidity requirements can also be met through short-term borrowings or the disposition of short-term assets.
While the Company does not anticipate any need for additional liquidity, in response to the uncertainty regarding the severity and duration of the COVID-19 pandemic, the Company has taken several actions to ensure the strength of its liquidity position. These actions include establishing a $1.8 billion Federal Reserve lending facility in connection with funding loans to small and medium-sized businesses and suspending stock repurchases effective as of April 17, 2020. In addition, the Company is also in a position to pledge additional collateral to increase its borrowing capacity with the FRB, if necessary.

The Company has a formal liquidity policy and, in the opinion of management, its liquid assets are considered adequate to meet cash flow needs for loan funding and deposit cash withdrawals for the next 90-120 days. At September 30, 2017,2020, there was $3.08$4.6 billion in liquid assets, comprised of $650.5 million$1.4 billion in cash and cash equivalents and money market investments and $2.43$3.1 billion in unpledged marketable securities. At December 31, 2016,2019, the Company maintained $2.00$2.9 billion in liquid assets,

comprised of $284.5$434.6 million of cash and cash equivalents and money market investments, and $1.72$2.5 billion of unpledged marketable securities.
The Parent maintains liquidity that would be sufficient to fund its operations and certain non-bank affiliate operations for an extended period should funding from normal sources be disrupted. Since deposits are taken by WAB and not by the Parent, Parent liquidity is not dependent on the Bank's deposit balances. In the Company's analysis of Parent liquidity, it is assumed that the Parent is unable to generate funds from additional debt or equity issuances, receives no dividend income from subsidiaries and does not pay dividends to stockholders, while continuing to make nondiscretionarynon-discretionary payments needed to maintain operations and repayment of contractual principal and interest payments owed by the Parent and affiliated companies. Under this scenario, the amount of time the Parent and its non-bank subsidiary can operate and meet all obligations before the current liquid assets are exhausted is considered as part of the Parent liquidity analysis. Management believes the Parent maintains adequate liquidity capacity to operate without additional funding from new sources for over twelve months.
WAB maintains sufficient funding capacity to address large increases in funding requirements, such as deposit outflows. This capacity is comprised of liquidity derived from a reduction in asset levels and various secured funding sources. On a long-term basis, the Company’s liquidity will be met by changing the relative distribution of its asset portfolios (for example, by reducing investment or loan volumes, or selling or encumbering assets). Further, the Company can increase liquidity by soliciting higher levels of deposit accounts through promotional activities and/or borrowing from correspondent banks, the FHLB of San Francisco, and the FRB. At September 30, 2017,2020, the Company's long-term liquidity needs primarily relate to funds required to support loan originations, commitments, and deposit withdrawals, which can be met by cash flows from investment payments and maturities, and investment sales, if necessary.
The Company’s liquidity is comprised of three primary classifications: 1) cash flows provided by operating activities; 2) cash flows used in investing activities; and 3) cash flows provided by financing activities. Net cash provided by or used in operating activities consists primarily of net income, adjusted for changes in certain other asset and liability accounts and certain non-cash income and expense items, such as the provision for credit losses, investment and other amortization and depreciation. For the nine months ended September 30, 20172020 and 2016,2019, net cash provided by operating activities was $271.1$450.1 million and $214.5$534.5 million, respectively.
The Company's primary investing activities are the origination of real estate and commercial loans, the collection of repayments of these loans, and the purchase and sale of securities. The Company's net cash provided by and used in investing activities has been primarily influenced by its loan and securities activities. The net increase in loans for the nine months ended September 30, 20172020 and 20162019 was $1.18$4.8 billion and $551.9 million,$2.4 billion, respectively. There was a net increase in investment securities for the nine months ended September 30, 20172020 and 2019 of $965.3$663.5 million compared to a net increase of $711.9and $221.1 million, for the nine months ended September 30, 2016.respectively.
Net cash provided by financing activities has been impacted significantly by increased deposit levels. During the nine months ended September 30, 20172020 and 2016,2019, net deposits increased $2.35$6.0 billion and $2.41$3.3 billion, respectively.

Fluctuations in core deposit levels may increase the Company's need for liquidity as certificates of deposit mature or are withdrawn before maturity, and as non-maturity deposits, such as checking and savings account balances, are withdrawn. Additionally, the Company is exposed to the risk that customers with large deposit balances will withdraw all or a portion of such deposits, due in part to the FDIC limitations on the amount of insurance coverage provided to depositors. To mitigate the uninsured deposit risk, the Company participates in the CDARS and ICS programs, which allow an individual customer to invest up to $50.0 million and $110.0$150.0 million, respectively, through one participating financial institution or, a combined total of $150.0$200.0 million per individual customer, with the entire amount being covered by FDIC insurance. As of September 30, 2017,2020, the Company has $409.1$449.3 million of CDARS and $587.2 million$1.1 billion of ICS deposits.
As of September 30, 2017,2020, the Company has $84.3$914.9 million of wholesale brokered deposits outstanding. Brokered deposits are generally considered to be deposits that have been received from a third party who is engaged in the business of placing deposits on behalf of others. A traditional deposit broker will direct deposits to the banking institution offering the highest interest rate available. Federal banking laws and regulations place restrictions on depository institutions regarding brokered deposits because of the general concern that these deposits are not relationship based and are at a greater risk of being withdrawn and placed on deposit at another institution offering a higher interest rate, thus posing liquidity risk for institutions that gather brokered deposits in significant amounts. There were also $260.2 million and $571.9 million of additional deposits as of September 30, 2017 and December 31, 2016, respectively, that the Company considers core deposits, but which are classified as brokered deposits for regulatory reporting purposes.
Federal and state banking regulations place certain restrictions on dividends paid. The total amount of dividends which may be paid at any date is generally limited to the retained earnings of the bank. Dividends paid by WAB to the Parent would be prohibited if the effect thereof would cause the bank’sBank’s capital to be reduced below applicable minimum capital requirements.

During the three months ended September 30, 2017, the Parent contributed $1.3 million to WAB and WAB and LVSP paid dividends to the Parent of $10.0 million and $4.8 million, respectively. During the nine months ended September 30, 2017, the Parent contributed $11.3 million to WAB and WAB and LVSP paid dividends to the Parent of $40.0 million and $27.3 million, respectively. Subsequent to September 30, 2017,2020, WAB paid dividends to the Parent of $30.0$15.0 million and $145.0 million, respectively. Subsequent to September 30, 2020, WAB paid dividends to the Parent of $15.0 million.

Supervision and Regulation
The following information is intended to update, and should be read in conjunction with, the information contained under the caption “Supervision and Regulation” in the Company’s Annual Report on Form 10-K and the supplemental disclosure related thereto contained under the same caption in the Company’s Form 10-Q for the quarter ended June 30, 2020.
CARES Act
On March 27, 2020, the CARES Act was passed by Congress and signed into law by the President. The CARES Act provided approximately $2.2 trillion in direct economic relief in response to the public health and economic impacts of COVID-19. Many of the CARES Act’s programs are, and remain, dependent upon the direct involvement of U.S. financial statements.institutions like the Company and the Bank. These programs have been implemented through rules and guidance adopted by federal departments and agencies, including the U.S. Department of Treasury, the Federal Reserve, and other federal bank regulatory authorities, including those with direct supervisory jurisdiction over the Company and the Bank. Furthermore, as the COVID-19 pandemic evolves, federal regulatory authorities continue to issue additional guidance with respect to the implementation, lifecycle, and eligibility requirements for the various CARES Act programs as well as industry-specific recovery procedures for COVID-19. In addition, it is possible that Congress will enact supplementary COVID-19 response legislation, including new bills comparable in scope to the CARES Act, prior to the end of 2020.

Set forth below is a brief overview of select provisions of the CARES Act and other regulations and supervisory guidance related to the COVID-19 pandemic that are applicable to the operations and activities of the Company and its subsidiaries, including the Bank. The following description is qualified in its entirety by reference to the full text of the CARES Act and the statutes, regulations, and policies described herein. Future legislation and/or amendments to the provisions of the CARES Act or changes to any of the statutes, regulations, or regulatory policies applicable to the Company and its subsidiaries could have a material effect on the Company. Such legislation and related regulations and supervisory guidance will be implemented over time and will remain subject to review by Congress and the implementing regulations issued by federal regulatory authorities. The Company continues to assess the impact of the CARES Act, the potential impact of new COVID-19 legislation, and other statutes, regulations, and supervisory guidance related to the COVID-19 pandemic.

Paycheck Protection Program. The CARES Act amended the SBA’s loan program, in which the Bank participates, to create a guaranteed, unsecured loan program, the PPP, to fund operational costs of eligible businesses, organizations and self-employed persons during COVID-19. On June 5, 2020, the President signed the PPPFA into law, which among other things, gave borrowers additional time and flexibility to use PPP loan proceeds. Shortly thereafter, and due to the evolving impact of the COVID-19 pandemic, the President signed additional legislation authorizing the SBA to resume accepting PPP applications on July 6, 2020 and extending the PPP application deadline to August 8, 2020. It is anticipated that additional revisions to the SBA’s interim final rules on forgiveness and loan review procedures, including potential Congressional legislation on those issues, will be forthcoming to address these and related changes. As a participating lender in the PPP, the Bank continues to monitor legislative, regulatory, and supervisory developments related thereto.
Troubled Debt Restructuring and Loan Modifications for Affected Borrowers. The CARES Act permits banks to suspend requirements under GAAP for loan modifications to borrowers affected by COVID-19 that would otherwise be characterized as TDRs and suspend any determination related thereto if (i) the loan modification is made between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the end of the COVID-19 emergency declaration, and (ii) the applicable loan was not more than 30 days past due as of December 31, 2019. Federal bank regulatory authorities also issued guidance to encourage banks to make loan modifications for borrowers affected by COVID-19 and to assure banks that they will not be criticized by examiners for doing so.
Federal Reserve Programs and Other Recent Initiatives
Main Street Lending Program. The CARES Act encouraged the Federal Reserve, in coordination with the Secretary of the Treasury, to establish or implement various programs to help midsize businesses, nonprofits, and municipalities. On April 9, 2020, the Federal Reserve proposed the creation of the MSLP to implement certain of these recommendations. On June 15, 2020, the Federal Reserve Bank of Boston opened the MSLP for lender registration. The MSLP supports lending to small and medium-sized businesses that were in sound financial condition before the onset of the COVID-19 pandemic. The MSLP operates through five facilities: the Main Street New Loan Facility, the Main Street Priority Loan Facility, the Main Street Expanded Loan Facility, the Nonprofit Organization New Loan Facility, and the Nonprofit Organization Expanded Loan Facility. The Federal Reserve Bank of Boston maintains the legal forms and agreements for eligible borrowers and eligible lenders to participate in the MSLP, and continues to refine the MSLP’s operational infrastructure and facilities. The Bank has registered as a lender under the MSLP and continues to monitor developments related thereto.

Temporary Regulatory Capital Relief related to Impact of CECL. Concurrent with enactment of the CARES Act, the federal bank regulatory authorities issued an interim final rule in late March 2020 that delayed the estimated impact on regulatory capital resulting from the adoption of CECL. Subsequently, on August 26, 2020, the federal banking agencies issued a final rule that allows institutions that adopt the CECL accounting standard in 2020 to mitigate CECL’s estimated effects on regulatory capital for two years. The CECL final rule is substantially similar to the interim final rule issued in March 2020 in connection with other CARES Act related regulatory relief. The final rule gives eligible institutions the option to mitigate the estimated capital effects of CECL for two years, followed by a three-year transition period. The Company has elected this capital relief option.
Supervisory Developments. On June 25, 2020, the Federal Reserve announced that it would take several actions to ensure large banks remain resilient despite the ongoing economic impact of COVID-19. Specifically, in the third quarter, the Federal Reserve will require large banks to preserve capital by suspending share repurchases, capping dividend payments, and allowing dividends according to a formula based on recent income. The Company and the Bank continue to monitor these developments, as well as other evolving supervisory responses to the COVID-19 pandemic, to assess what effect (if any) they will have, but do not anticipate any material impact at this time.
Modification of the Volcker Rule. Also on June 25, 2020, the Federal Reserve - along with the Commodity Futures Trading Commission, FDIC, the Office of the Comptroller of the Currency, and the SEC - issued a final rule modifying the Volcker Rule’s prohibition on banking entities investing in or sponsoring hedge funds or private equity funds (“covered funds”). The Volcker Rule generally prohibits banking entities from engaging in proprietary trading and from acquiring or retaining ownership interests in, sponsoring or having certain relationships with a hedge fund or private equity fund. The final rule modifies three areas of the Volcker Rule by: (1) streamlining the covered funds portion of the rule; (2) addressing the extraterritorial treatment of certain foreign funds; and (3) permitting banking entities to offer financial services and engage in other activities that do not raise concerns that the Volcker Rule was intended to address. The new rule became effective October 1, 2020. The Company and the Bank do not anticipate any material impact at this time from the new rule.

Item 3.Quantitative and Qualitative Disclosures about Market Risk.
Market risk is the risk of loss in a financial instrument arising from adverse changes in market prices and rates, foreign currency exchange rates, commodity prices, and equity prices. The Company's market risk arises primarily from interest rate risk inherent in its lending, investing, and deposit taking activities. To that end, management actively monitors and manages the Company's interest rate risk exposure. The Company generally manages its interest rate sensitivity by evaluating re-pricing opportunities on its earning assets to those on its funding liabilities.
Management uses various asset/liability strategies to manage the re-pricing characteristics of the Company's assets and liabilities, all of which are designed to ensure that exposure to interest rate fluctuations is limited to within the Company's guidelines of acceptable levels of risk-taking. Hedging strategies, including the terms and pricing of loans and deposits and management of the deployment of its securities, are used to reduce mismatches in interest rate re-pricing opportunities of portfolio assets and their funding sources.
Interest rate risk is addressed by the ALCO, which includes members of executive management, finance, and operations. ALCO monitors interest rate risk by analyzing the potential impact on the net EVE and net interest income from potential changes in interest rates and considers the impact of alternative strategies or changes in balance sheet structure. The Company manages its balance sheet in part to maintain the potential impact on EVE and net interest income within acceptable ranges despite changes in interest rates.
The Company's exposure to interest rate risk is reviewed at least quarterly by the ALCO. Interest rate risk exposure is measured using interest rate sensitivity analysis to determine its change in both EVE and net interest income in the event of hypothetical changes in interest rates. If potential changes to EVE and net interest income resulting from hypothetical interest rate changes are not within the limits established by the BOD, the BOD may direct management to adjust the asset and liability mix to bring interest rate risk within Board-approved limits.
Net Interest Income Simulation. In order to measure interest rate risk at September 30, 2017,2020, the Company usesused a simulation model to project changes in net interest income that result from forecasted changes in interest rates. This analysis calculates the difference between a baseline net interest income forecast using current yield curves that do not take into consideration any future anticipated rate hikes, compared to forecasted net income resulting from an immediate parallel shift in rates upward or downward, along with other scenarios directed by ALCO. The income simulation model includes various assumptions regarding the re-pricing relationships for each of the Company's products. Many of the Company's assets are floating rate loans, which are assumed to re-price immediately and, proportional to the change in market rates, depending on their contracted index, including the impact of caps or floors. Some loans and investments contain contractual prepayment features (embedded options) and, accordingly, the simulation model incorporates prepayment assumptions. The Company's non-term deposit products re-price more slowly, usually changing less thanconcurrently with interest rate changes taken by the change in market rates and at the Company's discretion.Federal Open Market Committee.
This analysis indicates the impact of changes in net interest income for the given set of rate changes and assumptions. It assumes the balance sheet remains static and that its structure does not change over the course of the year. It does not account for all factors that could impact the Company's results, including changes by management to mitigate interest rate changes or secondary factors, such as changes to the Company's credit risk profile as interest rates change.
Furthermore, loan prepayment rate estimates and spread relationships change regularly. Interest rate changes create changes in actual loan prepayment speeds that will differ from the market estimates incorporated in this analysis. Changes that vary significantly from the modeled assumptions may have significant effects on the Company's actual net interest income.

Economic Value of Equity. The Company measures the impact of market interest rate changes on the NPV of estimated cash flows from its assets, liabilities, and off-balance sheet items, defined as EVE, using a simulation model. This simulation model assesses the changes in the market value of interest rate sensitive financial instruments that would occur in response to an instantaneous and sustained increase or decrease (shock) in market interest rates.

The computation of prospective effects of hypothetical interest rate changes are based on numerous assumptions, including relative levels of market interest rates, asset prepayments, and deposit decay, and should not be relied upon as indicative of actual results. Further, the computations do not contemplate any actions the Company may undertake in response to changes in interest rates. Actual amounts may differ from the projections set forth above should market conditions vary from the underlying assumptions.

Evaluation of Disclosure Controls
Based on their evaluation as of the end of the period covered by this Quarterly Report on Form 10-Q, the CEO and CFO have concluded that the disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) are effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act, as amended, is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms. Additionally, the Company's disclosure controls and procedures were also effective in ensuring that information required to be disclosed by the Company in the reports it files or is subject to under the Exchange Act is accumulated and communicated to the Company's management, including the CEO and CFO, to allow timely decisions regarding required disclosures.

Item 1A.Risk Factors.
There have not been any material changes toItem 1A.Risk Factors.
Item 1A. Risk Factors of the risk factors previously disclosed in the Company'sCompany’s Annual Report on Form 10-K for the year ended December 31, 2016.2019 includes a discussion of the material risks and uncertainties that could adversely affect our business and impact our results of operations or financial condition. The information presented below updates, and should be read in conjunction with, the risk factors and information disclosed in the Annual Report on Form 10-K.
The COVID-19 pandemic and resulting adverse economic conditions have adversely impacted our business and results and could have a more material adverse impact on our business, financial condition and results of operations.
The ongoing COVID-19 global and national health emergency has caused significant disruption in the United States and international economies and financial markets. The spread of COVID-19 in the United States has caused illness, quarantines, cancellation of events and travel, business and school shutdowns, reduction in commercial activity and financial transactions, supply chain interruptions, increased unemployment, and overall economic and financial market instability. Many states, including Arizona, where we are headquartered, and California and Nevada, in which we have significant operations, declared states of emergency. These states, like many others, continue to be significantly impacted by the pandemic.
Although the Bank has continued operating, the COVID-19 pandemic has caused disruptions to our business and could cause material disruptions to our business and operations in the future. Impacts to our business have included the transition of a significant portion of our workforce to home locations, increases in costs due to additional health and safety precautions implemented at our branches, and an increase in draws on unfunded loan commitments and requests for forbearance and loan modifications. To the extent that commercial and social restrictions remain in place or increase, our expenses, delinquencies, foreclosures and credit losses may materially increase. In addition, the unprecedented nature of COVID-19 related disruptions heighten the inherent uncertainty of forecasting future economic conditions and their impact on our loan portfolio, and therefore increases the risk that the assumptions, judgments and estimates used to determine the appropriate allowance for future credit losses may prove to be incorrect, resulting in actual credit losses that exceed the Company’s recorded allowance.
Unfavorable economic conditions also may make it more difficult for us to maintain deposit levels and loan origination volume and to obtain additional financing. Furthermore, such conditions have and may continue to adversely impact accounting estimates that we use to determine our allowance and provision for credit losses. Such conditions also could impact the value of assets we carry on our balance sheet such as goodwill, and cause the value of collateral associated with our existing loans to decline. Further, certain debt and equity instruments may experience significant fluctuations in value due to market disruption, widening of credit spreads, and governmental purchase intervention. 
In addition, in March 2020, the Federal Reserve lowered the target range for the federal funds rate to a range from 0 to 0.25 percent, in part as a result of the pandemic. Sudden or unexpectedly large changes in interest rates could impact our ability to effectively manage our interest rate risk and could result in maturity imbalances in our assets and liabilities. A prolonged period of very low interest rates or an increase in interest rates that affects our borrowers' ability to repay loans could reduce our net interest income and have a material adverse impact on our cash flows.
While we have taken and are continuing to take actions to protect the safety and well-being of our employees and customers, no assurance can be given that the steps being taken will be deemed to be adequate or appropriate, nor can we predict the level of disruption which will occur to our employee's ability to perform their jobs or provide customer support and service. The continued or renewed spread of COVID-19 could negatively impact the availability of key personnel necessary to conduct our business, the business and operations of our third-party service providers who perform critical services for our business, or the businesses of many of our customers and borrowers. A sizable percentage of our workforce has returned to working in our office buildings, and it is possible that one or more members of our senior management or other key employees contracts the virus and is unable to perform their essential duties. At the same time, many of our employees and employees of companies we do business with continue to work remotely as a result of the pandemic, and the risk of cyber-attacks, breaches or similar events, whether through our systems or those of third parties on which we rely, therefore has increased.
Among the factors outside our control that are likely to affect the impact the COVID-19 pandemic will ultimately have on our business are:
the pandemic’s course and severity;
the direct and indirect results of the pandemic, such as recessionary economic trends, including with respect to employment, wages and benefits, commercial activity, consumer spending and real estate market values;
political, legal and regulatory actions and policies in response to the pandemic, including the effects of restrictions on commerce and banking, such as moratoria and other suspensions of collections, foreclosures, and related obligations;

the timing, magnitude and effect of public spending, directly or through subsidies, its direct and indirect effects on commercial activity and incentives of employers and individuals to resume or increase employment, wages and benefits and commercial activity;
the timing and availability of direct and indirect governmental support for various financial assets, including mortgage loans;
the potential long-term impact on the tourism and hospitality industries, which could affect our hotel franchise finance business and portfolio;
the long-term effect of the economic downturn on our intangible assets such as our deferred tax asset and goodwill;
potential longer-term effects of increased government spending on the interest rate environment and borrowing costs for non-governmental parties;
the ability of our employees and our third-party vendors to work effectively during the course of the pandemic;
potential longer-term shifts toward mobile banking, telecommuting and telecommerce; and
geographic variation in the severity and duration of the COVID-19 pandemic, including in states in which we operate physically such as Arizona, California and Nevada;
The ongoing COVID-19 pandemic has resulted in severe volatility in the financial markets and meaningfully lower stock prices for many companies, including our common stock. Depending on the extent and duration of the COVID-19 pandemic, the price of our common stock may continue to experience volatility and declines.
The Company is a participating lender in the PPP, a loan program administered through the SBA, that was created to help eligible businesses, organizations and self-employed persons fund their operational costs during the COVID-19 pandemic. Under this program, the SBA guarantees 100% of the amounts loaned under the PPP. Certain ambiguities in the laws, rules and guidance regarding the requirements and operation of the PPP may expose the Company to risks relating to noncompliance with the PPP. For instance, other financial institutions have experienced litigation related to their policies and procedures for accepting and processing applications for the PPP. Any financial liability, litigation costs or reputational damage caused by PPP related litigation could have a material adverse impact on our business, financial condition and results of operations. In addition, the Company may be exposed to credit risk on a PPP loan if a determination is made by the SBA that there is a deficiency in the manner in which the loan was originated, funded or serviced. In such a case, the SBA may deny its liability under the guaranty, reduce the amount of the guaranty, or, if it has already paid under the guaranty, seek recovery of any related loss from the Company.
We are continuing to monitor the COVID-19 pandemic and related risks, although the rapid development and fluidity of the situation precludes any specific prediction as to its ultimate impact on us. However, if the pandemic continues to spread or otherwise results in a continuation or worsening of the current economic and commercial environments, our business, financial condition, results of operations and cash flows, as well as our regulatory capital and liquidity ratios, could be materially adversely affected.
