Conservatism

tl;drAn accounting principle that advocates recording uncertain items in the way that will result in least likely overstatement of assets and income.

This concept requires recognizing potential losses and expenses as soon as they become probable, while only recognizing gains and revenue when they are certain. Consider a company facing a lawsuit with uncertain outcome. Under the conservatism principle, they would record a liability for the estimated potential loss even if not certain, but would not recognize potential settlement gains until actually received. Similarly, inventory would be valued at the lower of cost or market value to avoid overstating assets. Applying conservatism requires professional judgment in estimating uncertainties and timing of recognition. While preventing overoptimistic reporting, excessive conservatism can understate financial position.
