Deposit risk is a type of liquidity risk of a financial institution that is generated by deposits either with defined maturity dates (then such deposits are called 'time' or 'term' deposits) or without defined maturity dates (then such deposits are called 'demand' or 'non-maturity' deposits).

The trinomial tree is a lattice-based computational model used in financial mathematics to price options on equity. It was developed by Phelim Boyle in 1986. It is an extension of the binomial options pricing model, and is conceptually similar. It can also be shown that the approach is equivalent to the explicit finite difference method for option pricing.
