In May 2014, FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606). The ASU creates a new topic, Topic 606, to provide guidance on revenue recognition for entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets. The core principle of the guidance is 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. Additional disclosures are required to provide quantitative and qualitative information regarding the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new guidance iswas effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2016. However, in April 2015, the FASB voted to defer the effective date of ASU 2014-09 by one year making, the amendments effective for public entities for annual reporting periods beginning after December 15, 2017, including interim periods within those reporting periods.  Companies have the option to apply ASU 2014-09 as of the original effective date. Early adoption is not permitted. The Bank plans to adopt these amendments during the first quarter of 2018.  Management is currently evaluatingcontinuing to evaluate the impact ASU 2014-09 will have on the Bank's consolidated financial statements as well as the most appropriate transition method of application.  Based on this evaluation to date, Management has determined that the majority of the revenues earned by the Bank are not within the scope of ASU 2014-09.  Management also believes that for most revenue streams within the scope of ASU 2014-09, the amendments will not change the timing of when the revenue is recognized.  Management will continue to evaluate the impact the adoption of this guidanceASU 2014-09 will have on the Company’sBank's consolidated financial statements, focusing on noninterest income sources within the scope of ASU 2014-09 as well as new disclosures required by these amendments; however, the adoption of ASU 2014-09 is not expected to have a material impact on the Bank's consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.  The ASU makes several modifications to Subtopic 825-10 including the elimination of the available-for-sale classification of equity investments, and requires equity investments with readily determinable fair values to be measured at fair value with changes in fair value recognized in net income.  This ASU will become effective for the Company for interim and annual periods beginning after December 15, 2017. The adoption of ASU No. 2016-01 is not expected to have a material impact on the Company's financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This standard requires organizations to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing requirements for leases that were historically classified as operating leases under previous generally accepted accounting principles. This ASU will become effective for the Company for interim and annual periods beginning after December 15, 2018.  The Company leases some of its branch locations.  Upon adoption of this standard, an asset will be recorded to recognize the right of the Company to use the leased facilities and a liability will be recorded representing the obligation to make all future lease payments on those facilities.  Management is currently evaluating the impact ofamounts to be recognized upon the adoption of this guidance onin the Company’sCompany's financial statements.

In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting.  This ASU will require recognition of the income tax effects of share-based awards in the income statement when the awards vest or are settled (i.e., Additional Paid-in-Capital pools will be eliminated).  The guidance in this ASU will become effective for interim and annual reporting periodswas adopted by the Company beginning after December 15, 2016, with early adoption permitted.January 1, 2017.  The adoption of ASU No. 2016-09 isdid not expected to have a material impact on the Company's financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments.  This ASU replaces the measurement for credit losses from a probable incurred estimate with an expected future loss estimate, which is referred to as the “current"current expected credit loss”loss" or “CECL”"CECL".  The standard pertains to financial assets measured at amortized cost such as loans, debt securities classified as held-to-maturity, and certain other contracts.  The largest impact will be on the allowance for loan and lease losses.  This ASU will become effective for the Company for interim and annual periods beginning after December 15, 2019. Management is currently evaluating the impact of the adoption of this guidance on the Company’sCompany's financial statements.
