(a) The assets in this category represent investments in foreign equity and bond funds. Generally, these assets are valued using bid-market valuations provided by the funds’ investment managers.

(b) The assets in this category represent investments in an absolute return strategies fund. Generally, these assets are valued at the net asset value as determined by the custodian of the fund. The net asset value is based on the underlying investments, which are valued using inputs such as quoted market prices of identical instruments, discounted future cash flows, independent appraisals, and market-based comparable data. As such, the assets in this category have been categorized as Level 2 in the fair value hierarchy.

(c) The assets in this category include investments in a liability driven investment fund and investments in commercial real estate. The liability driven investment fund is a single priced fund and the fair value of the underlying assets are priced by the fund’s custodian based on observable market data and therefore categorized as Level 2 in the fair value hierarchy. The investments in commercial real estate primarily represent a property unit trust that invests in commercial real estate properties in the U.K. The fair values for these investments are based on inputs obtained from broker quotes that are indicative of value and cannot be corroborated by observable market data and therefore are categorized as Level 3 in the fair value hierarchy.
