Annual rest在法律中，通常有两层含义：

1. 年度假期

2. 即是其在信托法中的意思，年结算期。

在利息法中，如果为避免使受托人获取衡平法院不能允许的利益而向其计征复利〔compound interest〕，则该利息应每年在指定的年结算期中进行计算。在该结算期中，向受托人收取利息，并向其支付佣金和该年度的合法费用。

这里的rest就是指的利息的结算期：

The term defines the periodicity at which the principal amount is reduced as the borrower repays. Rests are usually monthly, quarterly and annual. A monthly rest recalculates the reduced principal after each equated monthly instalment (EMI), and then applies the interest rate on the reduced principal.

与之相应的还有季结算期、月结算期、日结算期等，分别为quarterly rest、monthly rest以及daily rest。

以下为相关双语示例，供参考：

Let us assume that your bank has to process an Annual Rest Loan with a tenor of 36 months. Oracle Lending processes such loans in the following manner:

At the start of every 12 month period, the monthly interest installment amount for the next 12 months will be computed based on the outstanding principal at the start of the 12-month period.

At the start of the 12 month period, the total interest amount for the next 12 months is passed to an Unearned GL (the interest amount is unearned as you will be calculating the interest for a future period).

假设您的银行必须处理期限为36个月的年度结算贷款。Oracle Lending会以以下方式处理此类贷款：

在每12个月期间开始时，未来12个月的每月利息分期付款金额将根据12个月期间开始时的未偿还本金计算。
