Employee Stock Ownership Plan
 
We established a leveraged Employee Stock Ownership Plan (“ESOP”) in 1990. The ESOP covered substantially all domestic employees. The shares required for our 401(k) matching contribution program were provided principally by our ESOP, supplemented as needed by newly issued shares. We made annual contributions to the ESOP equal to the ESOP's debt service less dividends and Company match contributions received by the ESOP. All dividends received by the ESOP were used to pay debt service. The ESOP shares initially were pledged as collateral for its debt. As the debt was repaid, shares were released from collateral and allocated to employees who made 401(k) contributions that year, in the form of a matching contribution, based on the proportion of debt service paid in the year. Shares pledged as collateral were reported as unearned ESOP shares in the Consolidated Balance Sheets. As shares were released from collateral, we reported compensation expense equal to the cost of the shares to the ESOP. All ESOP shares were considered outstanding in earnings-per-share computations, and dividends on allocated and unallocated shares were recorded as a reduction of Retained Earnings.
 
The benefit provided through the ESOP was net of expenses and was recorded in Other Income. On December 31, 2009, the ESOP's twenty year loan matured and was repaid to us, completing the term for this ESOP.
