(a) General. This section prescribes rules pertaining to the close out of royalty payments accounts in accordance with 17 U.S.C. 1005.

(b) In the Register's discretion, four years after the close of any calendar year, the Register of Copyrights may close out the royalty payments account for that calendar year, including any sub-accounts, that are subject to a final distribution order under which royalty payments have been disbursed. Following closure of an account, the Register will treat any funds remaining in that account, or subsequent deposits that would otherwise be attributable to that calendar year, as attributable to the succeeding calendar year.
