# Realized and Unrealized Performance Summary in Base

This section shows profit and loss by underlying and asset class.

An alternative to the Mark-to-Market (MTM) profit and loss calculation is the calculation in which closing transactions are matched to opening transactions and a profit or loss is realized when a position is closed. Open positions are marked-to-market and the resulting profit or loss is unrealized.

To determine the realized profit or loss, we make an assumption about which opening transaction should match the closing transaction. There are a number of methods for determining this: First In, First Out (FIFO, in which the oldest positions are recorded as having been closed first), Last In, First Out (LIFO, in which the newest positions are recorded as having been closed first), Average Cost, and Specific Lot.
