Mark to market is an accounting calculation tracking the current market value of an asset. Mark-to-market calculations are typically done daily. Mark to market is based on the current market value of the assets in question (i.e., commodity, security, derivatives, etc.) Mark to market reflects how much such assets would be sold for if they were put on the market today. Methodologies used in the mark-to-market calculation are classified on two different levels. Level 1: market-prices for the asset are available and can be used in the mark-to-market calculation. Level 2: no market prices are available.
