Futures Narrowly Mixed After Economic Data

European shares were higher after Greece's international creditors secured a deal to reduce the troubled nation's debt by 40 billion euros ($51.9 billion) and changed the debt target for the country to 124 percent of gross domestic product (GDP) by 2020, from 120 percent previously.

Jean-Claude Juncker, the head of the Eurogroup of finance ministers, said Greece would receive a tranche of 34.4 billion euros of aid on December 13, for which it has been waiting since June.

Negotiations are expected to resume this week as policymakers return to Washington from the Thanksgiving holiday.
