Arthur,

Options always have time premia, though it decreases over time. The rate of decrease of the price of the option is given by the options theta. An example from Hull:

Say stock price is 305, strike is 300, dividend yield is 3%, interest rate is 8% and volatility is 25%/annum, then the options theta is -18.51/annum (ignoring the calculation as the CBOE options calculator does it for you).

This means that everything else remaining the same, in 1 year the option price will decrease by 18.15. The theta increases for LEAPS as time goes on.

Hope this helps.
