Organization, Consolidation and Presentation of Financial Statements [Abstract]
New Authoritative Accounting Guidance	New Authoritative Accounting Guidance In July 2013, the Financial Accounting Standards Board issued an accounting standard update, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists.” This standard requires netting of unrecognized tax benefits against a deferred tax asset for a loss or other carryforward that would apply in settlement of the uncertain tax positions. This standard is effective prospectively for annual and interim periods beginning after December 15, 2013. The adoption of this guidance did not have a significant effect on the consolidated financial statements.
