MASTER TRUST MASTER TRUST
The majority of the Plan’s investment assets are held in a trust account by the Trustee and consist of an undivided interest in investment accounts of the Master Trust. Use of the Master Trust permits the commingling of trust assets with the assets of other plans sponsored by the Company for investment and administrative purposes. Although assets of the plans are commingled in the Master Trust, the Recordkeeper maintains supporting records for the purpose of allocating the net gain or loss of the investment account to the participating plans. The net investment income or loss of the investment assets and administrative expenses are allocated by the Recordkeeper to each participating plan based on the relationship of the interest of each plan to the total of the interests of the participating plans.
The Master Trust is subject to master netting agreements, or netting arrangements, with certain counterparties. These agreements govern the terms of certain transactions, and reduce the counterparty risk associated with relevant transactions by specifying offsetting mechanisms and collateral posting arrangements at pre-arranged exposure levels. Since different types of transactions have different mechanics and are sometimes traded out of different legal entities of a particular counterparty organization, each type of transaction may be covered by a different master netting arrangement possibly resulting in the need for multiple agreements with a single counterparty. Master netting agreements are specific to each different asset type; therefore, they allow the Master Trust to net its total exposure to a specified counterparty and settle it through a single payment, in a single currency in the event of a default with respect to any and all the transactions governed under a single agreement with the counterparty.
