This report presents the results of the actuarial valuation of the Plymouth Contributory Retirement System. The valuation was performed as of January 1, 2015 pursuant to Chapter 32 of the General Laws of the Commonwealth of Massachusetts. The actuarial assumptions used in this valuation are the same as those used in the January 1, 2013 valuation with the exception of the investment return assumption (reduced from 7.75% to 7.5%) and the mortality assumption which now reflects a fully generational table. This valuation was based on member data as of December 31, 2014, which was supplied by the Retirement Board. Such tests as we deemed necessary were performed on the data to ensure accuracy. Asset information as of December 31, 2014 was provided in the Annual Statement for the Financial Condition as submitted to this office in accordance with G.L. c. 32, ss. 20(5)(h), 23(1) and 23(2)(e). Both the membership data and financial information were reviewed for reasonableness, but were not audited by us.
