Accounting Policies [Abstract]
Recent accounting pronouncements	In June 2011, the FASB issued an accounting standards update concerning the presentation of comprehensive income in financial statements. This guidance allows an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. Under both options, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. This guidance eliminates the option to present the components of other comprehensive income only as part of the statement of changes in shareholders' equity. The guidance does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The Company adopted the guidance from January 1, 2012; however, it did not have an impact on the Company's disclosure, financial condition or results of operations or cash flows. In February 2013, the FASB issued an additional accounting standards update related to this topic that requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The guidance was adopted prospectively from January 1, 2013. As this guidance is disclosure-related only and does not change the current requirements for reporting net income or other comprehensive income in financial statements, its adoption did not impact the Company's financial condition, results of operations or cash flows. In December 2011, the FASB issued an accounting standards update requiring additional disclosures about financial instruments and derivatives that are either: (1) offset for balance sheet presentation purposes or (2) subject to an enforceable master netting arrangement or similar arrangement, regardless of whether they are offset for balance sheet presentation purposes. In January 2013, the FASB issued an additional accounting standards update related to this topic clarifying that the disclosures would apply only to derivatives, repurchase and reverse repurchase agreements, and securities borrowing and securities lending transactions, each to the extent that they met one of the two conditions provided in the initial accounting standards update. This guidance was adopted from January 1, 2013, on a retrospective basis for all fiscal periods presented. As this guidance is disclosure-related only and does not amend existing balance sheet offsetting guidance, its adoption did not impact the Company's financial condition, results of operations or cash flows.
