Staff of two divisions of the Commodity Futures Trading Commission issued an interpretation to the International Swaps and Derivatives Association permitting covered swap entities that collect and post margin on a portfolio basis to include both security-based swaps and swaps in their calculations, subject to certain enumerated conditions. Among other things, both the swaps and security-based swaps must be subject to the same eligible master netting agreement and applicable netting portfolio. The two divisions are the Division of Swap Dealer and Intermediary Oversight and the Division of Clearing and Risk.
