A 3% uplift clause is now worked out for you

A lease that says "the rent then payable multiplied by 1.03 on each anniversary" states a rule, not a rent. Until now the increases only reached your figures if the extraction had written the resulting levels out, or you typed them in on the review screen. When it did not, the lease was imported at the opening rent for the whole term and the liability was understated by every increase the lease had already agreed, with nothing on screen to say anything was missing.

Lease102 now reads the clause and does the arithmetic. Each review date gets its own rent period at the computed rate, compounding on the rent then payable unless the lease says the uplift applies to the original rent. The computed rows appear on the review screen marked as computed, showing the clause they came from, and you can edit them like any other row before approving.

Open-market and index-linked reviews are deliberately left alone. A payment that depends on an index or on market rents is measured at the rate in force at the commencement date, and the liability is remeasured when the change actually takes effect. Computing future levels for one would put a forecast on your balance sheet. Where a document carries such a clause, the review screen names it and its first review date, so you know it is there.
