Accounting Changes

In September 2011, the Financial Accounting Standards Board (“FASB”) amended its guidance related to the disclosure of multi-employer pension plans. The guidance requires incremental disclosures that provide additional information related to an employer's financial obligations within multi-employer pension plans. The provisions of the amended guidance were effective for the Company in the year ending December 31, 2011. The Company adopted the provisions of the amended accounting standard during the fourth quarter of 2011. The provisions have been applied retrospectively. See Note 11 of the Consolidated Financial Statements.
