At December 31, 2011, unrealized losses in the investment securities portfolio relating to debt securities totaled $1.1 million. The unrealized losses on these debt securities arose due to changing interest rates and are considered to be temporary. At December 31, 2011, six out of 147 securities issued by state and political subdivisions contained unrealized losses and 43 out of 105 securities issued by U.S. Government sponsored enterprises, including mortgage-backed securities, contained unrealized losses. These unrealized losses are considered temporary because of acceptable investment grades on each security and the repayment sources of principal and interest are government backed.

The Company periodically evaluates its investments for any impairment which would be deemed other-than-temporary. As part of its evaluation in 2011, the Company determined that the fair value of one equity security was less than the original cost of the investment and that the decline in fair value was not temporary in nature. As a result, the Company wrote down its investment by $144,000. The remaining fair value of the investment at December 31, 2011 was approximately $264,000. Similarly, as part of its evaluation in 2010, the Company wrote down two equity securities by $291,000. The remaining fair value of the investments at December 31, 2010 was $409,000.

The amortized cost and estimated fair value of investment securities available for sale at December 31, 2011, by contractual maturity, are shown below. Expected maturities of mortgage-backed securities will differ from contractual maturities because borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

GAAP establishes a framework for measuring fair value and expands disclosures about fair value measurements. There is a three-level fair value hierarchy for fair value measurements. Level 1 inputs are quoted prices in active markets for identical assets or liabilities that a company has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. The table below presents the balance of securities available for sale and derivatives, which are measured at fair value on a recurring basis by level within the fair value hierarchy as of December 31, 2011 and 2010.

Fair values of investment securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges when available. If quoted prices are not available, fair value is determined using matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities' relationship to other benchmark quoted securities. Fair values of derivative instruments are determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities.

The following is an analysis of fair value measurements of investment securities available for sale using Level 3, significant unobservable inputs, for the year ended December 31, 2011:
