ISDA CDS Standard Model
The ISDA CDS Standard Model is a source code for CDS calculations and can be downloaded freely through this website.

The source code is copyright of ISDA and available under an Open Source license.

 
Background

As the CDS market evolves to trade single name contracts with a fixed coupon and upfront payment, it is critical for CDS investors to match the upfront payment amounts and to be able to translate upfront quotations to spread quotations and vice versa in a standardized manner.

One of the primary goals in making the code available is to enhance transparency and to optimize use of standard technology for CDS pricing. Implementing the ISDA CDS Standard Model and using the agreed standard input parameters will allow CDS market participants to tie out calculations and thus improve consistency and reduce operational differences downstream.

The new 'Bullet Syndicated Secured Loan Credit Default Swap' contract is scheduled to launch on 5-April.  This will coincide with the rolling of the Markit LCDX.NA Index.  The new Bullet LCDS will be a 'Standard' Contract trading with a full first coupon, accruing from the previous quarterly roll date (20-Mar / Jun / Sep / Dec).  There will be four available coupons, paid quarterly: 0, 100, 250 and 500 basis points (bps), with most of the liquidity expected to be at 250 bps.From Series 14 onwards, LCDX will also trade with a full first coupon, fixed at 250 bps for the new Series.  The ISDA CDS Standard Model will be used to calculate fees for the Single Name and Index contracts, using a 70% recovery assumption.  The Markit CDS Converter at http://www.markit.com/cds supports these calculations.
