Recently Adopted Accounting Pronouncements	In December 2010, the FASB issued an update to modify Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts.

In determining whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. The qualitative factors are consistent with the existing guidance, which requires that goodwill of a reporting unit be tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The adoption of this accounting guidance did not have a material impact on our financial position, results of operations or liquidity.
Recently Issued Accounting Standards	In June 2011, the FASB issued guidance regarding the presentation of comprehensive income.

Recently Adopted Accounting Pronouncements

In December 2010, the FASB issued an update to modify Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. The qualitative factors are consistent with the existing guidance, which requires that goodwill of a reporting unit be tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The adoption of this accounting guidance did not have a material impact on our financial position, results of operations or liquidity.
