Mortality rates were based on the RP-2014 mortality tables, with adjustments for LGERS experience and generational mortality improvements using Scale MP-2015. The demographic actuarial assumptions for retirement, disability incidence, withdrawal, and salary increases used in the June 30, 2016 valuation were based on the results of an actuarial experience study for the period January 1, 2010 - December 31, 2014, adopted by the LGERS.

Discount rate The discount rate used to measure the total OPEB liability was based on the LIRR and the SEIR. The projection of cash flows used to determine the discount rate assumed that contributions from employers will be made to pay benefits directly to Plan members as they come due and to contribute $500,000 to the OPEB Benefit Trust each year. Based on these assumptions, the Plan’s fiduciary net positon was projected to be available to make all projected future benefit payments of the current Plan members until 2026. Therefore, the long-term expected rate of return on OPEB investments was applied to those periods of projected benefit payments and then the SEIR was used to determine the total OPEB liability. Sensitivity of the City’s net OPEB liability to changes in the discount rate The following presents the City’s net OPEB liability calculated using the discount rate of 4.02 percent, as well as what the City’s net OPEB liability would be if it were calculated using a discount rate that is one percentage point lower (3.02 percent) or one percentage point higher (5.02 percent) than the current rate:
