[2] As indicated in Note 4 of Item 8 of this Form 10-K, the Company has a full valuation allowance against its net deferred tax asset. In 2012, 2011 and 2010, the Company's net deferred tax asset valuation increased mainly due to the "naked credit" discussed in Note 4 and the deferred taxes on other comprehensive loss items. In 2010, the Company refined its process to apply the liability method of accounting to better estimate its deferred taxes. This methodology adjusted the 2010 net deferred tax assets as a result of comparing the tax basis balance sheet and the financial accounting balance sheet; net deferred tax assets had a corresponding and offsetting change in the valuation allowance that resulted in no impact to net income. Amounts shown in the "Other" column for 2012, 2011 and 2010 also include various adjustments to deferred taxes identified in preparation of the federal income tax return for the preceding year.
