The Master Trust’s investment at contract value is a stable-value fund, which invests in traditional and alternative guaranteed investment contracts (GICs). GICs are contracts between an issuer and the Plan that provide for a fixed return on principal amounts invested over a fixed period of time. As described in Note 2, because the investment contracts are fully benefit-responsive, contract value is the relevant measurement attribute for that portion of the net assets available for benefits attributable to the investment contracts. Contract value represents contributions made under the contract, plus earnings, less participant withdrawals and administrative expenses. Net assets and net investment income/loss are allocated to participating plans based on number of units owned. Participants may ordinarily direct the withdrawal or transfer of all or a portion of their investment at contract value. Alternative GICs (a form of wrap contract) are typically paired
