Stock index futures pared gains on Friday after mixed data on U.S. durable goods orders and consumer spending.

S&P 500 futures rose 4 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures gained 45 points, and Nasdaq 100 futures added 8.75 points.

U.S. November durable goods orders rose 3.8 percent, more than the 2.0 percent forecast and above October's flat reading.

U.S. consumer spending rose less than expected in November as tepid income growth put a squeeze on households, according to a government report that suggested slowing momentum in demand.
