Use "time-value" in a sentence
"The time-value of money is priced into the cost of the option because the retail options market (at least for puts and calls on large-cap publicly traded companies) is EXTREMELY transparent and competitive."
"If option pricing did not take into account the time-value of money, then a bank that sold you a put option would on average turn a profit on that option even after subtracting out the transaction fee; after all, it would mean you were giving them an interest-free loan."
"When I strive to remember, I have a riot of unrelated impressions and a loss of time-value."
