Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2018

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. These estimates and assumptions also impact reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A summary of the significant accounting policies to assist the reader in understanding the financial presentation is provided in the Notes to Consolidated Financial Statements in the Form 10-K.

Cash and cash equivalents

Cash and cash equivalents includes Cash and due from banks and amounts due from the Federal Reserve Bank (FRB). Cash on hand, cash items in the process of collection, and amounts due from correspondent banks are included in Cash and due from banks. Amounts due from the FRB are interest-bearing for all periods presented and are included in the Interest-bearing due from banks line on the Company’s Consolidated Balance Sheets.

This table provides a summary of cash and cash equivalents as presented on the Consolidated Statements of Cash Flows as of September 30, 2018 and September 30, 2017 (in thousands):

	September 30,
	2018		2017
Due from the FRB	$	635,993	$	182,047
Cash and due from banks		348,700		366,169
Cash and cash equivalents at end of period	$	984,693	$	548,216

Also included in the Interest-bearing due from banks, but not considered cash and cash equivalents, are interest-bearing accounts held at other financial institutions, which totaled $33.0 million and $39.8 million at September 30, 2018 and September 30, 2017, respectively.

Per Share Data

Basic net income per share is computed based on the weighted average number of shares of common stock outstanding during each period. Diluted quarter-to-date net income per share includes the dilutive effect of 438,927 and 549,819 shares issuable upon the exercise of options granted by the Company and outstanding at September 30, 2018 and 2017, respectively. Diluted year-to-date net income per share includes the dilutive effect of 470,897 and 616,990 shares issuable upon the exercise of options granted by the Company and outstanding at September 30, 2018 and 2017, respectively.

Options issued under employee benefits plans to purchase 135,157 and 150,739 shares of common stock were outstanding at September 30, 2018 and 2017, respectively, but were not included in the computation of quarter-to-date and year-to-date diluted earnings per share because the options were anti-dilutive.

Derivatives

The Company records all derivatives on the Consolidated Balance Sheets 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. Currently, three of the Company’s derivatives are designated in qualifying hedging relationships. However, the remainder of the Company’s derivatives are not designated in qualifying hedging relationships, as the derivatives are not used to manage risks within the Company’s assets or liabilities. All changes in fair value of the Company’s non-designated derivatives are recognized directly in earnings. Changes in fair value of the Company’s fair value hedges are recognized directly in earnings. Changes in fair value of the Company’s cash flow hedges are recognized in accumulated other comprehensive income (AOCI).
