To develop the expected long-term rate of return on assets assumption, the Company considered the historical returns and the future expectations for returns for each asset class, as well as the target asset allocation of the pension portfolio.

The investment strategy of the plans is to ensure, over the long-term life of the plan, an adequate pool of assets along with contributions by the Company to support the benefit obligations to participants, retirees, and beneficiaries. The Company desires to achieve market returns consistent with a prudent level of diversification. All investments are made solely in the interest of each plan's participants and beneficiaries for the exclusive purposes of providing benefits to such participants and their beneficiaries and defraying the expenses related to administering the plan. The target allocation of all assets is to reflect proper diversification in order to reduce the potential of a single security or single sector of securities having a disproportionate impact on the portfolio. The Company utilizes an outside investment consultant and investment manager to implement its investment strategy. Plan assets are generally invested in liquid funds that are selected to track broad market equity and bond indices. Investment performance of plan assets is reviewed semi-annually and the investment objectives are evaluated over rolling four year time periods.

Plan Contributions

The Company’s participation in these plans for the annual period ended December 31, 2014, is outlined in the table below. The “EIN/Pension Plan Number” column provides the Employee Identification Number (EIN) and the three-digit plan number, if applicable. Unless otherwise noted, the most recent Pension Protection Act (PPA) zone status available in 2014 and 2013 is for the plan’s year-end as of December 31, 2013 and December 31, 2012, respectively. The zone status is based on information the Company received from the plan and is certified by the plan’s actuary. Among other factors, plans in the red zone are generally less than 65 percent funded, plans in the yellow zone are less than 80 percent funded, and plans in the green zone are at least 80 percent funded. The “FIP/RP Status Pending/Implemented” column indicates plans for which a financial improvement plan (FIP) or a rehabilitation plan (RP) is either pending or has been implemented. This last column lists the expiration date(s) of the collective-bargaining agreement(s) to which the plans are subject. The Company's contributions to the Teamsters Pension Trust Fund of Philadelphia and Vicinity have not exceeded 5% of total plan contributions for the fiscal years 2014, 2013 or 2012.

(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.
