Materiality of Unrecorded Adjustments
The Company does not record all immaterial adjustments in its consolidated financial statements. The Company performs a materiality analysis based on all relevant quantitative and qualitative factors. Effective December 31, 2006 the Company quantifies materiality of unrecorded adjustments in accordance with Staff Accounting Bulletin 108, Considering the Effects of Prior Year Misstatements when Quantifying Measurements in Current Year Financial Statements (SAB 108) issued by the Securities and Exchange Commission (the SEC). The impact on the current year financial statements of recording all potential adjustments, including both the carryover and reversing effects of amounts not recorded in prior years, are considered. Unrecorded adjustments are quantified using a balance sheet and an income statement approach which considers both (1) the amount of the misstatement originating in the current year income statement (generally referred to as the Rollover approach) and (2) the cumulative amount of the misstatements at the end of the current year (generally referred to as the Iron Curtain approach). Prior to December 31, 2006, the Company used only the Rollover approach to quantify the materiality of unrecorded adjustments.
