Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. The Company has selected November 30 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on First Defiance’s balance sheet. Other intangible assets consist of core deposit and acquired customer relationship intangible assets arising from whole bank, insurance and branch acquisitions.

Accounting Standards Adopted in 2019 In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842). The guidance in the update supersedes the requirements in ASC Topic 840, Leases. The guidance is intended to increase transparency and comparability among organizations by recognizing right-of-use assets and lease liabilities on the balance sheet. For public companies, this update was effective for interim and annual periods beginning after December 15, 2018. The Company adopted this guidance in the first quarter of 2019. Upon adoption, the Company elected a practical expedient which allows existing leases to retain their classification as operating leases. The Company has elected to account for lease and related non-lease components as a single lease component. The Company has also elected to not recognize right-of-use assets and lease liabilities arising from short-term leases, which are twelve months or less. Implementation of the guidance resulted in the recording of a right-of-use asset and lease liability on the balance sheet; however it does not have a material impact on the Company's other consolidated financial statements. See additional disclosures in Note 10. Accounting Standards Updates In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments.” This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. In issuing the standard, the FASB is responding to criticism that today’s guidance delays recognition of credit losses. The standard will replace today’s “incurred loss” approach with an “expected loss” model. The new model, referred to as the current expected credit loss (“CECL”) model, will apply to: (1) financial assets subject to credit losses and measured at amortized cost, and (2) certain off-balance sheet credit exposures. This includes, but is not limited to, loans, leases, held-to-maturity securities, loan commitments, and financial guarantees. The CECL model does not apply to available-for-sale (“AFS”) debt securities. For AFS debt securities with unrealized losses, entities will measure credit losses in a manner similar to what they do today, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. As a result, entities will recognize improvements to estimated credit losses immediately in earnings rather than as interest income over time, as they do today. The ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans. ASU 2016-13 also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the allowance for loan and lease losses. In addition, entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. ASU No. 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019. As a result of this ASU, the Company could experience an increase in its allowance. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (i.e., modified retrospective approach). Interagency guidance issued in December 2018 allows for a three-year phase-in of the cumulative-effect adjustment for regulatory capital reporting purposes. The Company continues its implementation efforts through its established Company-wide implementation committee along with a third-party software vendor to assist in the implementation process. The committee’s review indicates the Company has maintained sufficient historical loan data to support the requirement of this pronouncement and is currently evaluating the various loss methodologies to determine their correlations to the Company’s loan segments historical performance. The Company is currently running parallel computations in 2019 and continues to evaluate the impact of adoption of this ASU.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.

Earnings Per Common Share

Basic earnings per common share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for the calculation. Diluted earnings per common share include the dilutive effect of additional potential common shares issuable under stock options, restricted stock awards and stock grants.

Goodwill and Other Intangibles

Goodwill resulting from business combinations prior to January 1, 2009, represents the excess of the purchase price over the fair value of the net assets of businesses acquired. Goodwill resulting from business combinations after January 1, 2009, is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. The Company has selected November 30 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on First Defiance’s balance sheet.
