[1] The Trustees of the Teamsters Pension Trust Fund of Philadelphia and Vicinity elected to apply the special amortization and special asset valuation provisions provided for under the Preservation of Access to Care for Medicare Beneficiaries and Pension Relief Act of 2010 (PRA 2010) for Plan Years beginning January 1, 2009 and later. The special amortization rule allows that portion of the plan’s experience loss attributable to net investment losses incurred in the year ended December 31, 2008 to be amortized over a 30-year period rather than a 15-year period. The special asset valuation rule allows the recognition of investment losses in the year ended December 31, 2008 to be spread over a 10-year period rather than a 5-year period.
