U.S. stock index futures pared their gains Thursday following policy announcements from both the Bank of England and the European Central Bank and as investors digested a pair of mixed economic reports.
On the economic front, weekly jobless claims fell 5,000 last week to a seasonally adjusted 366,000, according to the Labor Department. Economists surveyed by Reuters expected a reading of 368,000.
Meanwhile, productivity fell 2 percent in the fourth quarter, declining by the most in nearly two years, according to the Labor Department's preliminary reading. And unit labor costs jumped at a 4.5 percent rate in the fourth quarter. Economists expected productivity to slide 1.3 percent, while unit labor costs were estimated to climb 3.0 percent.
In Europe, the ECB decided to maintain its main interest rate at 0.75 percent. Meanwhile, ECB Chief Mario Draghi may also face questioning on French President Francois Hollande's call for a target rate for the euro, as well as on his connection to the scandal at Italy's Banca Monte dei Paschi di Siena (Monte Paschi).
In addition, a two-day European Union (EU) summit is scheduled to kick off in Brussels, the first since British Prime Minister David Cameron confirmed the country will hold a referendum on EU membership.
