S&P futures turned flat on Friday after being negative as U.S. core consumer prices were below expectations for March.

The government said the Consumer Price Index rose 0.5 percent last month, lifted by food and energy prices.

But excluding those goods, prices were up only 0.1 percent.

Futures had been in negative territory earlier, pressured by disappointing results from Bank of America Corp and Google Inc

S&P 500 futures rose 0.1 point and were about even with 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 fell 23 points and Nasdaq 100 futures fell 6.75 point.
