The proceeds derived from the sale of cotton shall be held for the Secretary of Agriculture by the Treasurer of the United States in a special deposit account and shall be used by the Secretary of Agriculture to discharge the obligations incurred under authority of sections
603,
604, and
607 of this title. Whenever any cotton shall be marketed the net proceeds (after discharge of other obligations incurred with respect thereto) derived from the sale thereof shall be used, to the extent required, to reimburse the Treasury for such portion of the funds hereby provided for as shall have been used, which shall be covered into the Treasury as a miscellaneous receipt. If when all of the cotton acquired by the Secretary of Agriculture shall have been marketed and all of the obligations incurred with respect to such cotton shall have been discharged, and the Treasury reimbursed for any and all sums which may have been advanced pursuant to subsection (b) of this section, there shall remain any balance in the hands of the Secretary of Agriculture, such balance shall be covered into the Treasury as miscellaneous receipts.
The word “obligation” when used in this section shall include (without being limited to) administrative expenses, warehouse charges, insurance, salaries, interest, costs, commissions, and other expenses incident to handling, carrying, insuring, and marketing of said cotton.
