This guidance is effective for fiscal years and interim periods, beginning after December 15, 2011. Early application by public companies is not permitted.

This guidance is effective for fiscal years and interim periods, beginning after December 15, 2011. The Company's adoption of ASU 2011-05 will not have an impact on its consolidated results of operations or financial condition.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In September 2011, the FASB issued ASU No. 2011-08, Topic 350 - </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Intangibles - Goodwill and Other</font><font style="font-family:inherit;font-size:10pt;"> ("ASU 2011-08"), which amends Topic 350 to allow an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. An entity would not be required to calculate the fair value of a reporting unit unless the entity determines, based the qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. This guidance is effective for annual and interim goodwill tests performed for years beginning after December 15, 2011. Early adoption is permitted.

Under U.S. GAAP, certain derivative and repurchase agreement arrangements are granted exceptions from the general off-setting model. To facilitate comparison between financial statements prepared under U.S. GAAP and IFRS, the new disclosure requirement will provide financial statement users information regarding both gross and net exposures. This guidance is effective for annual and interim financial statements beginning on or after January 1, 2013. Retrospective application is required. The Company does not set off related arrangements associated with its financial instruments and derivative instruments. Its adoption of ASU 2011-11 is not expected to have an impact on its consolidated results of operations or financial condition.</font></div></div>

An entity would not be required to calculate the fair value of a reporting unit unless the entity determines, based the qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount.

Under U.S. GAAP, certain derivative and repurchase agreement arrangements are granted exceptions from the general off-setting model. To facilitate comparison between financial statements prepared under U.S. GAAP and IFRS, the new disclosure requirement will provide financial statement users information regarding both gross and net exposures.
