bilateral portfolio compression exercise
The term bilateral portfolio compression exercise means an exercise by which two security-based swap counterparties wholly terminate or change the notional value of some or all of the security-based swaps submitted by the counterparties for inclusion in the portfolio compression exercise and, depending on the methodology employed, replace the terminated security-based swaps with other security-based swaps whose combined notional value (or some other measure of risk) is less than the combined notional value (or some other measure of risk) of the terminated security-based swaps in the exercise.
