There is a war risk insurance revolving fund in the Treasury.

There shall be deposited in the fund amounts appropriated to carry out this chapter and amounts received in carrying out this chapter.

There shall be paid from the fund amounts for return premiums, losses, settlements, judgments, and all liabilities incurred by the United States Government under this chapter.
