Investment Securities

Securities to be held for indefinite periods, but not intended to be held to maturity, are classified as available for sale and carried at fair value. Securities held for indefinite periods include securities that management intends to use as part of its asset and liability management strategy and that may be sold in response to liquidity needs, changes in interest rates, resultant prepayment risk, and other factors related to interest rate and resultant prepayment risk changes.

Realized gains and losses on dispositions are based on the net proceeds and the adjusted book value of the securities sold, using the specific identification method. Unrealized gains and losses on investment securities available for sale are based on the difference between book value and fair value of each security. These gains and losses are credited or charged to other comprehensive income, whereas realized gains and losses flow through the Corporation's results of operations.

ASC Topic 320, Investments – Debt and Equity Securities, clarifies the interaction of the factors that should be considered when determining whether a debt security is other-than-temporarily impaired. For debt securities, management must assess whether (a) it has the intent to sell the security and (b) it is more likely than not that it will be required to sell the security prior to its anticipated recovery. These steps are done before assessing whether the entity will recover the cost basis of the investment. Previously, this assessment required management to assert it has both the intent and the ability to hold a security for a period of time sufficient to allow for an anticipated recovery in fair value to avoid recognizing other-than-temporary impairment. This change does not affect the need to forecast recovery of the value of the security through either cash flows or market price.

In instances when a determination is made that other-than-temporary impairment exists but the investor does not intend to sell the debt security and it is not more likely than not that it will be required to sell the debt security prior to its anticipated recovery, this guidance changes the presentation and amount of the other-than-temporary impairment recognized in the income statement. The other-than-temporary impairment is separated into (a) the amount of the total other-than-temporary impairment related to a decrease in cash flows expected to be collected from the debt security (the credit loss) and (b) the amount of the total other-than-temporary impairment related to all other factors. The amount of the total other-than-temporary impairment related to the credit loss is recognized in earnings. The amount of the total other-than-temporary impairment related to all other factors is recognized in other comprehensive income.

Management evaluates securities for other-than-temporary impairment at least on a quarterly basis; and more frequently when economic or market concerns warrant such evaluation. Consideration is given to the length of time and the extent to which the fair value has been less than cost, and the financial condition and near term prospects of the issuer. In addition, for debt securities, the Corporation considers (a) whether management has the intent to sell the security, (b) it is more likely than not that management will be required to sell the security prior to its anticipated recovery, and (c) whether management expects to recover the entire amortized cost basis. For equity securities, management considers the intent and ability to hold securities until recovery of unrealized losses.

At December 31, 2011, Mid Penn had 45 debt securities with unrealized losses. These securities have depreciated 1.37% from their amortized cost basis. At December 31, 2010, 30 debt securities with unrealized losses had depreciated 3.60% from the amortized cost basis. These securities are issued by either the U.S. Government or other governmental agencies. These unrealized losses were determined principally by reference to current interest rates for similar types of securities. In analyzing an issuer's financial condition, management considers whether the U.S. Government or its agencies issued the securities, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuer's financial condition. Based on the above conditions management has determined that no declines are deemed to be other-than-temporary.

The table below is the maturity distribution of investment securities at amortized cost and fair value at December 31, 2011 and 2010:
