On April 24, 2013, the International Swaps and Derivatives Association (ISDA) issued a release announcing the publication of a form of confirmation for a Market Agreed Coupon (MAC) contract. The MAC Contract is voluntary and is meant to compliment bespoke interest rate swaps (IRS) and deliverable interest rate futures. The intent of the new MAC swaps are to help improve liquidity to interest rate swap products as they become more accessible to investors, and also serve to enhance market transparency.
