Calculation method

Calculation method

Conversion amount = principal + accrued interest; shares = conversion amount ÷ conversion price.

Fixed-decimal arithmetic remains exact through display unless a result is explicitly labelled approximate, such as a square-root inventory quantity.

Worked example

Worked example

Principal 100,000, accrued interest 8,000, and price 8 give 13,500 conversion shares.

Conversion amount = principal + accrued interest; shares = conversion amount ÷ conversion price.
