The new guidance revises the manner in which entities present comprehensive income in their financial statements. ASU 2011-5 requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. The ASU does not change the items that must be reported in other comprehensive income. This guidance required a change in the presentation of the financial statements and required retrospective application. The Company retrospectively adopted this guidance utilizing two separate but consecutive statements to report the components of other comprehensive income, and recast the financial statements for the years ending 2011, 2010 and 2009 in the Company's current Report on Form 8-K filed on July 16, 2012. The standard had no impact on the Company's financial position, results of operations or cash flows.</font></div></div>
