NOTE 1 NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES continued CONSOLIDATION The consolidated financial statements include the accounts of the Corporation and all its subsidiaries, after elimination of all material intercompany transactions. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (table dollar amounts in thousands, except share data) INVESTMENT SECURITIES-Debt securities are classified as held to maturity when the Corporation has the positive intent and ability to hold the securities to maturity. Securities held to maturity are carried at amortized cost. Debt securities not classified as held to maturity are classified as available for sale. Securities available for sale are carried at fair value with unrealized gains and losses reported separately in accumulated other comprehensive income, net of tax. Amortization of premiums and accretion of discounts are recorded as interest income from securities. Realized gains and losses are recorded as net security gains (losses). Gains and losses on sales of securities are determined on the specific-identification method. LOANS HELD FOR SALE are carried at the lower of aggregate cost or market. Market is determined using the aggregate method. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income based on the difference between estimated sales proceeds and aggregate cost. LOANS held in the Corporation’s portfolio are carried at the principal amount outstanding. Certain nonaccrual and substantially delinquent loans may be considered to be impaired. A loan is impaired when, based on current information or events, it is probable that the Banks will be unable to collect all amounts due (principal and interest) according to the contractual terms of the loan agreement. In applying the provisions of Statement of Financial Accounting Standards ("SFAS") No. 114, the Corporation considers its investment in one-to-four family residential loans and consumer installment loans to be homogeneous and therefore excluded from separate identification for evaluation of impairment. Interest income is accrued on the principal balances of loans, except for installment loans with add-on interest, for which a method that approximates the level yield method is used. The accrual of interest on impaired loans is discontinued when, in management's opinion, the borrower may be unable to meet payments as they become due. When interest accrual is discontinued, all unpaid accrued interest is reversed when considered uncollectable. Interest income is subsequently recognized only to the extent cash payments are received. Certain loan fees and direct costs are being deferred and amortized as an adjustment of yield on the loans. 28
