ASX will be implementing a fix, effective from Monday, 24 August 2020, to resolve an issue with the calculation of OIS coupons caused by a one day lag of receipt of the RBA Overnight Cash Rate (OCR). Price Alignment Amount (PAA) will apply at the prevailing RBA OCR rate available on each business day.
This fix will result in the OCR being mapped to the correct date (with no lag). See example outlined below:

*PAA = MtMT x RateT x D/365 (for definitions refer to the ASX OTC Handbook)
There are no changes Participants OTC reports as part of this implementation.
Post implementation, if necessary a final set of coupon and portfolio balance adjustments will be made.
To be aware of the fix and update processes accordingly.
