Defined Benefit Plans
Effective for the year ended December 31, 2006, the Company adopted the required provisions of SFAS 158, which resulted in the recognition of the overfunded and underfunded statuses of the Companys defined benefit plans as assets or liabilities, as appropriate. In addition, other comprehensive income includes gains or losses and prior service costs or credits that arose during the year but were not recognized as components of net periodic benefit cost. The effect of the adoption of these provisions on the Companys assets, liabilities and shareholders equity as of December 31, 2006 was as follows:
(1) The benefit asset and net deferred tax assets are included in other assets.
(2) The benefit liability is included in other liabilities.
Beginning in 2007, the Company will recognize changes in the funded statuses in the year in which the changes occur through other comprehensive income. Effective December 31, 2008, the Company will measure plan assets and benefit obligations as of the date of the balance sheet.
