Using proceeds from a loan from the Company, the ESOP purchased 8%, 222,180 2007. 7.75% 15 Shares of the Company’s common stock purchased by the ESOP are held in a suspense account and reported as unallocated common stock held by the ESOP in stockholders’ equity until released for allocation to participants. As the debt is repaid, shares are released from collateral and are allocated to each eligible participant based on the ratio of each such participant’s base compensation to the total base compensation of eligible plan participants. As the unearned shares are committed to be released and allocated among participants, the Company recognizes compensation expense equal to the average market value of the shares, and the shares become outstanding for earnings per share computations.

Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan Losses. no The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated.

The specific component relates to loans that are designated as impaired. For loans that are designated as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers pools of loans by loan class. These pools of loans are evaluated for loss exposure based upon historical loss rates for each of these categories of loans, adjusted for qualitative factors. These significant factors may A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not A loan is identified as a troubled debt restructuring (“TDR”) if the Company, for economic or legal reasons related to a debtor’s financial difficulties, grants a concession to the debtor that it would not For loans secured by real estate, estimated fair values are determined primarily through third The allowance calculation methodology includes further segregation of loan classes into risk rating categories.
