Profit is what is left after subtracting purchase price or production cost from selling price.
Bonds, (term) certificates of deposits, commercial papers… mature.
Returns, interest earned, accruals, realized capital gains…are distributed or paid out when they become due before or at/on maturity.
Expiration or expiry happens when a contract or agreement ceases to be effective (valid).
People expire, too, but bank deposits, savings, bonds…do not.
