(a) Subject to paragraph (b) of this section, futures commission merchants and derivatives clearing organizations may hold Cleared Swaps Customer Collateral in the denominations, at the locations and depositories, and subject to the segregation requirements specified in § 1.49 of this chapter.

(b) Notwithstanding the requirements in § 1.49 of this chapter, a futures commission merchant's obligations to a Cleared Swaps Customer may be denominated in a currency in which funds have accrued to the Cleared Swaps Customer as a result of a Cleared Swap carried through such futures commission merchant, to the extent of such accruals.

(c) Each depository referenced in paragraph (a) of this section shall be considered a Permitted Depository for purposes of this part. Provided, however, that a futures commission merchant shall only be considered a Permitted Depository to the extent that it is acting as a Collecting Futures Commission Merchant (as § 22.1 of this part defines such term).
