## Table 0 ##
Although the Company believes it has adequately provided for all uncertain tax positions, amounts asserted by taxing authorities could be greater than the Company's accrued position.
Accordingly, additional provisions for federal and state income tax related matters could be recorded in the future as revised estimates are made or the underlying matters are effectively settled or otherwise resolved.
Conversely, the Company could settle positions with the tax authorities for amounts lower than have been accrued.
The Company believes that it is reasonably possible that during the next 12 months the Company's liability for uncertain tax positions may decrease by $14 million due to resolution of a federal uncertain tax position.
During 2013 the Company entered into the pre-Compliance Assurance Process with the IRS for years 2011 and 2012.
The Company is part of the IRS Compliance Assurance Process program for the 2014 through 2018 tax years.
Open tax years related to state jurisdictions remain subject to examination.
Deferred Income Taxes - Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and for income tax purposes.
