Stock index futures fell on Thursday as renewed concerns about the euro zone's financial health pushed down the euro and European shares.

* The euro, which has been closely correlated with global equities, tumbled to a 15-month low against the dollar and an 11-year low versus the yen as investors questioned the ability of European banks to raise capital amid the region's debt crisis.

* European shares were lower on Thursday, led by bank stocks as sovereign yields rose across the region after a French debt auction. <.EU>

* French borrowing costs rose slightly when the euro zone's second-largest economy sold debt for the first time this year on Thursday. Demand was solid despite concerns the country could lose its AAA credit rating and offered relief that the bloc's stronger sovereigns can still smoothly manage an escalation of the debt crisis for now.

* Investors awaited U.S. employment data, with the December ADP National Employment report due at 8:15 a.m. EST, and weekly jobless claims figures coming at 8:30 a.m. EST. That will set the tone for Friday's December all-important non-farm payrolls report.

* A Reuters survey showed economists expected a reading of 178,000 for the ADP report, down from 206,000, and a reading of 375,000 for weekly jobless claims, down from 381,000.

* December's U.S. ISM non-manufacturing index is to be released at 10 a.m. EST. The index is seen at 53.0 versus 52.0.

* Some market participants anticipate the U.S. stock market will be less affected by Europe's debt crisis if the jobs data further evidence solid economic recovery.

* S&P 500 futures fell 8.5 points and were below 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 lost 66 points, and Nasdaq 100 futures were off 9.25 points.

* Apple Inc has appointed Adobe Systems Inc executive Todd Teresi to head its iAd mobile-advertising business, Bloomberg reported, citing sources. Apple shares were down 0.3 percent at $412.14 in premarket trade.

* Major U.S. stock indexes were little changed in a low-volume session on Wednesday, but some investors were encouraged to see equities avoid a selloff amid lingering euro zone's debt problems.
