The Company is currently evaluating the impact of this guidance, however it is not expected to have a material impact on the Company’s consolidated financial statements.

The objective of ASU 2011-05 is to improve the comparability, consistency and transparency of financial reporting and to increase the prominence of items reported in other comprehensive income.
