The WRS receives funding from three separate sources: employee contributions, employer contributions and investment earnings. Together, these must be sufficient to meet the present and future pension benefit commitments of the system. This "shared risk" feature is a major contributor to the stability and sound funding of the WRS, which is considered one of the best-designed, well-governed public pension plans in the U.S.

Keep in mind these important points:

  • Your WRS retirement benefit is pre-funded. Contributions and investment earnings are deposited into your account during your working years.
  • The ETF Board's consulting actuary annually examines WRS funding requirements to ensure the system can meet its obligations.
  • Core Trust Fund investment returns are smoothed over a five-year period. Smoothing helps mitigate the effects of stock market volatility and, therefore, works to keep annual contribution rate changes stable.
