# The Profit and Loss Equation in Compressions | A Short Video

This video explains “Realised” and “Unrealised” profits and losses, key concepts in derivatives trading. Furthermore, this equation drives portfolio compressions.

Shrinking a portfolio of transactions is about keeping the same profits and price risk while reducing those side effects that derivative trading firms have to deal with after a transaction is executed: operational, credit and regulatory risks. The profit and losses (P&L) that happened in the past, is usually referred to as the "Realised P&L". Earnings to be made in the future are called "Unrealised P&L". These two components add up to the total profits and losses in a portfolio.

[Realised P&L + Unrealised P&L]Before compression ≈ [Realised P&L + Unrealised P&L]After compression

This video explains the equation that should be kept in the minds of those involved in compressions. The equation ensures that profits stay the same before and after reducing transactions in a portfolio. The following timeline should help viewers to follow the parts they are most interested on.
