The Standard Credit Support Annex (SCSA or Standard CSA) seeks to standardize market practice regarding embedded optionality in current CSAs, promote the adoption of overnight index swap discounting for derivatives, and align the mechanics and economics of collateralization between the bilateral and cleared OTC derivative markets. Additionally, the SCSA seeks to create a homogeneous valuation framework, reducing current barriers to novation and valuation disputes. (This is an update of the original, dated November 2011.)
