[1] Fixed income securities are comprised primarily of international government agency and international corporate bonds with investment grade ratings.

[2] Equity securities consist of an international mutual fund that invests solely in international stocks that are actively traded on international exchanges.

[3] Other asset holdings are comprised primarily of international bond futures and a derivatives-based mutual fund that invests in various assets.

[4] The fair value of the mutual fund is generally valued based on closing prices from national exchanges, if the underlying securities are traded on an active market, or fixed income pricing models that use observable market inputs.
