Funding and Liquidity Plans
Each principal operating subsidiary and/or country must prepare a Funding and Liquidity Plan for approval by the Treasurer and independent risk management. For significant entities, as defined by balance sheet size and the liquidity risk position, the Funding and Liquidity Plan is prepared and approved on an annual basis. The Funding and Liquidity Plan addresses strategic liquidity issues and establishes the parameters for identifying, measuring, monitoring and limiting liquidity risk and sets forth key assumptions for liquidity risk management. The Funding and Liquidity Plan includes analysis of the balance sheet, as well as the economic and business conditions impacting, or potentially impacting, the liquidity of the major operating subsidiary and/or country. As part of the Funding and Liquidity Plan, liquidity limits, liquidity ratios, market triggers, and assumptions for periodic stress tests are established and approved.
