Covered (C) liabilities are those covered by budgetary resources. Uncovered (U) Liabilities are those not covered by budgetary resources. As an example, there will generally be congressionally approved budget resource earmarked for liquidation of the current portion of environmental liabilities. This is an example of a covered liability. On the other hand, there will generally not be budgetary resources in place for the liquidation of the long-term portion of environmental liabilities (resources will be allocated as the liability becomes more immediate). The latter is an example of an uncovered liability.
