Recent Accounting Pronouncement [Abstract]

The guidance requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. generally accepted accounting principles to be reclassified in its entirety to net income. For other amounts that are that are not required under U.S. generally accepted accounting principles to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. generally accepted accounting principles that provide additional detail about those amounts. The new guidance is effective prospectively for reporting periods beginning after December 15, 2012, with early adoption permitted. The Company adopted the new guidance in the first quarter of 2013 with no material impact on its financial statements.
