Recently Issued Accounting Standards [Abstract]

Recently Issued Accounting Standards

3. Recently Issued Accounting Standards

          In December 2010, the FASB issued updated accounting guidance to clarify that pro forma disclosures should be presented as if a business combination occurred at the beginning of the prior annual period for purposes of preparing both the current reporting period and the prior reporting period pro forma financial information. These disclosures should be accompanied by a narrative description about the nature and amount of material, nonrecurring pro forma adjustments. The new accounting guidance is effective for business combinations consummated in periods beginning after December 14, 2010, and should be applied prospectively as of the date of adoption. Early adoption is permitted. We have adopted the new disclosures as of January 1, 2011.
