Accounting Policies [Abstract] |
Business and Consolidation | Basis of Financial Statement Presentation The accompanying unaudited condensed consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with the accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. The condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated. In the opinion of management, the consolidated financial statements contain all adjustments (consisting of normal recurring accruals) considered necessary for the fair presentation of the statements of financial position, results of operations, and cash flow for the interim periods. Recently Adopted Accounting Pronouncements During the first quarter of 2019, the Company adopted Accounting Standards Update (“ASU”) 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities.” ASU 2017-08 shortens the amortization period of certain callable debt securities held at a premium to the earliest call date. The adoption of this update did not have a material effect on the Company's consolidated financial statements. The Company adopted ASU 2016-02 “Leases (Topic 842)” using the optional transition method effective on January 1, 2019. ASU 2016-02 requires organizations that lease assets to recognize the assets and liabilities for the rights and obligations created by leases. The Company recorded $15.5 million for right-to-use assets and $16.2 million for lease liabilities related to operating leases. The Company elected the practical expedients package which eliminates (1) the need to reassess whether any expired or existing contracts are or contain a lease, (2) the need to reassess the lease classification, and (3) the need to reassess initial direct costs for any existing leases. The Company also elected an accounting policy to not recognize assets and liabilities on leases 12 months or less, and an accounting policy for equipment and real estate leases to not separate nonlease components because the impact was immaterial. Acquisitions Acquisitions and business combinations are accounted for using the acquisition method of accounting. The assets and liabilities of the acquired entities have been recorded at their estimated fair values at the date of acquisition. Goodwill represents the excess of the purchase price over the fair value of net assets acquired, including the amount assigned to identifiable intangible assets. The purchase price allocation process requires an estimation of the fair values of the assets acquired and the liabilities assumed. When a business combination agreement provides for an adjustment to the cost of the combination contingent on future events, the Company includes an estimate of the acquisition-date fair value as part of the cost of the combination. To determine the fair values, the Company utilizes third party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. The results of operations of the acquired business are included in the Company’s consolidated financial statements from the date of acquisition. Merger-related costs are costs the Company incurs to effect a business combination. The Company presents merger-related expenses as a separate component of noninterest expenses on the Condensed Consolidated Statements of Operations. Merger-related expenses include costs directly related to merger or acquisition activity and include legal and professional fees, system consolidation and conversion costs, gain or loss on sale of investment securities incurred through repositioning the acquired investment portfolio, and compensation costs such as severance and retention incentives for employees impacted by acquisition activity. The Company accounts for merger-related costs as expenses in the periods in which the costs are incurred and the services are received. Revenue The Company’s revenues are primarily composed of interest income on financial instruments, including investment securities. Other noninterest income is primarily comprised of service charges on deposit accounts, wealth management revenue, card services revenue and gains on sale of other real estate. Descriptions of our revenue-generating activities, which are presented in our income statement as components of noninterest income, are as follows:
• | Service charges on deposit accounts - represents fees generated from a variety of deposit products and services provided to customers under a day-to-day contract. These fees are recognized on a daily or monthly basis.
• | Wealth management revenue - represents monthly fees earned from directing, holding, and managing customers’ assets. Revenue is recognized over regular intervals, either monthly or quarterly.
• | Card services revenue - represents revenue earned from merchant, debit and credit cards as incurred and includes a contra revenue account for rebates.
• | Gain on sale of other real estate - represents income recognized at delivery of control of a property at the time of a real estate closing.
Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets on our consolidated balance sheet. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made prior to commencement and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. We account for the lease and non-lease components as a single lease component. Assumptions and judgments are used in applying ASC 842 and may include (1) the decision framework for identifying a lease, (2) the accounting policy election for equipment and real estate leases to not separate nonlease components, and (3) the discount rate for determining the initial present value of the lease payments which is based on information available at the commencement date for determining the lease term and assessing if optional periods are reasonably likely to be exercised. For the calculation at January 1, 2019, the discount rate was based on the remaining lease terms. Derivative Instruments and Hedging Activities FASB ASC 815, Derivatives and Hedging (“ASC 815”), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments. The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply, or the Company elects not to apply hedge accounting. The Company does not offset derivative asset and liability positions. However, the Company's exposure to the credit risk of its derivative financial instruments is generally mitigated by master netting agreements with its counterparties. The Alternative Reference Rates Committee (“ARRC”) has proposed that the Secured Overnight Funding Rate (“SOFR”) replace LIBOR. ARRC has proposed the transition to SOFR from LIBOR until the end of 2021. The Company has material contracts indexed to LIBOR. Industry organizations are currently working on the transition plan. The Company is monitoring this activity and evaluating the risks involved.
Available-for-sale Securities | Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include among other considerations (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, (4) structure of the security, and (5) the intent to sell the security or whether it is more likely than not the Company would be required to sell the security before its anticipated recovery in market value. At September 30, 2019, management performed its quarterly analysis of all securities with an unrealized loss and concluded no individual securities were other-than-temporarily impaired.
