Data for the Quarterly Survey of Public Pensions have been collected on a quarterly basis since 1968. The collection starts at the beginning of each calendar quarter and continues for about three months. Revenue collected, payments made, and asset amounts are as of the end of each calendar quarter (March, June, September, and December).
Effective with the first quarter of 2012, the Survey of the Finances of Public Employee Retirement Systems was renamed to the Quarterly Survey of Public Pensions (QSPP). Several other modifications and improvements were made to the survey at the same time. In Part 1, realized net gains or losses was separated from unrealized net gains or losses. In Part 3, the asset Federally-sponsored agency securities was moved from Corporate Bonds to Federal Government Securities. Additionally, private equity, venture capital, and leveraged buy-outs were moved from Other Securities to Corporate Stocks.
Usable replies are received from at least 80 percent of the systems canvassed.
