Calculation method
Calculation method
TERP = (old shares × market price + new shares × subscription price) ÷ total shares.
Fixed decimal scalar arithmetic remains exact until display. Square-root and compound projections are explicitly approximate and reject non-finite results.
Worked example
Worked example
A 1-for-4 issue at 8 when the market price is 10 gives TERP 9.60 and theoretical right value 0.40.
TERP = (old shares × market price + new shares × subscription price) ÷ total shares.
Supported inputs
Precision and limits
