In accounting, the convention of conservatism, also known as the doctrine of prudence, is a policy of anticipating possible future losses but not future gains. This policy tends to understate rather than overstate net assets and net income, and therefore lead companies to "play safe". When given a choice between several outcomes where the probabilities of occurrence are equally likely, you should recognize that transaction resulting in the lower amount of profit, or at least the deferral of a profit.
