ASU 2011-11 is effective for annual periods beginning on or after January 1, 2013 and interim periods within those annual periods. An entity should provide the disclosures required by these amendments retrospectively for all comparative periods presented. The adoption of ASU 2011-11 is not expected to have a significant impact on the Company's consolidated financial statements.
