Accumulated Other Comprehensive Income (Loss)
ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS)

The sole component of accumulated other comprehensive income (loss) ("AOCI") is pension and postretirement health and life benefit plans. Amortization of actuarial (gains) losses, net and the amortization of prior service costs (credit) are items reclassified from AOCI and included in the computation of net benefit costs as detailed in Note 12. Additionally, the pension liability (unfunded status) and AOCI declined $138.3 million as of June 30, 2013 as a result of the freeze of the defined benefit pension plans in 2013.
