The mortality tables used to determine benefit obligations as of December 31, 2015, 2014 and 2013 consisted of the following: RP 2014 generational mortality table with MP  2015 and MP 2014 projection scale and no collar adjustment for 2015 and 2014, respectively, and the PPA Separate static annuitant and nonannuitant tables for 2013.
The discount rate used by the Company in calculating the net periodic benefit cost for the Pension Plan and the Supplemental Pension Plan was determined using the Mercer Pension Discount Yield Curve  Above Mean Yield. The Above Mean Curve is constructed from the bonds in the Mercer Yield Curve universe that have a yield higher than the Regression Mean Yield Curve.
In developing the expected long‑term rate of return on assets, the Plan evaluates input from investment consultants, actuaries, and investment management firms based on their long term investment outlook and computation of historical returns. Expectations of returns for each asset class are the most significant of the assumptions used in developing the expected long‑term return on assets. The Company then utilizes a forward‑looking building block approach based on the asset class allocations.
