NEW YORK, Sept 15 (Reuters) - U.S. stock index futures rose on Thursday after three days of market gains as investors welcomed signs that European leaders are committed to keeping Greece afloat for now.

Investor sentiment was given a boost after Wednesday's conference call between leaders of France, Germany and Greece showed a commitment to keep debt-stricken Greece in the euro zone.

S&P 500 futures gained 6.9 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 were up 60 points, and Nasdaq 100 futures added 20.25 points.

"I have no doubt that Greece stays in the euro zone," said Peter Boockvar, equity strategist at Miller Tabak + Co in New York. "It's just the state of their balance sheet that needs to be fixed and that will ultimately be done through a 50 percent plus cut to the value of their existing debt outstanding."

Germany and France called on Greece to implement all financial reforms "strictly and effectively," a German government spokesman said. [ID:nP6E7JV05E].

Greece expects policymakers to report the government is on track to fulfill its targets and receive the aid needed to avoid a debt default, a Greek official said.
