Note 1—Summary of Significant Accounting Policies and Nature of Operations (Continued)
Cash and Cash Equivalents
Cash and cash equivalents include cash and due from banks, interest bearing deposits in banks, and federal funds sold.
Trading Account Assets and Liabilities
Trading account assets and liabilities are recorded at fair value and include certain securities and derivatives. Securities are classified as trading when management acquires them as an accommodation to customers or with the intent to hold for short periods. Substantially all of these securities have a high degree of liquidity and a readily determinable fair value. Interest on securities classified as trading is included in interest income, and realized gains and losses from sale and unrealized fair value adjustments are recognized in noninterest income.
Derivatives included in trading account assets and liabilities are entered into as an accommodation to customers or for other risk management purposes, primarily to manage the Bank’s exposure to certain interest rate risks. Contracts primarily include interest rate swaps and options and foreign exchange contracts. The Bank nets derivative assets and liabilities, and the related cash collateral receivables and payables, when a legally enforceable master netting arrangement exists between the Bank and the derivative counterparty. Changes in fair values and realized income or expense for trading asset and liability derivatives are included in noninterest income.
Securities
Securities are recorded on the consolidated balance sheet as of the trade date, when acquired in a regular-way trade. Debt securities for which management has both the positive intent and ability to hold to maturity are classified as held to maturity and are carried at amortized cost. Debt securities that are not classified as trading assets or held to maturity are classified as available for sale and are carried at fair value, with the unrealized gains or losses reported net of taxes as a component of AOCI in stockholder’s equity until realized. However, unrealized losses on securities available for sale that we intend to sell, or if it is more likely than not that we will be required to sell, before recovery of the security’s amortized cost basis are included in noninterest income. Credit losses on securities available for sale that we do not expect to sell and credit losses on securities held to maturity, if any, are recorded as discussed in “Allowance for Credit Losses” in this note.
Interest income on debt securities classified as either available for sale or held to maturity includes the amortization of premiums and the accretion of discounts using a method that produces a level yield based on the estimated lives of the securities and is included in interest income on securities.
Realized gains and losses on the sale of available for sale securities are included in noninterest income. The specific identification method is used to calculate realized gains and losses on sales.
For further information on our debt securities, see Note 2 to these consolidated financial statements.
Loans Held for Investment, Loans Held for Sale and Leases
Loans held for investment are reported at the principal amounts outstanding, net of charge-offs, unamortized nonrefundable loan fees, direct loan origination costs, and purchase premiums and discounts. Where loans are held for investment, the net basis adjustment excluding charge-offs on the loan is generally recognized in interest income on an effective yield basis over the contractual loan term.
Nonaccrual loans are those for which management has discontinued accrual of interest because there exists significant uncertainty as to the full and timely collection of either principal or interest. Loans are generally placed on nonaccrual when such loans have become contractually past due 90 days with respect to principal
