The euro area’s fourth-quarter gross domestic product declined 0.3 percent from the third quarter, the European Union’s statistics office said today, confirming an initial estimate published on Feb. 15.

The 12 members of the creditors’ steering committee that said they would join in the exchange of Greek debt have debt with a face value of at least 40 billion euros, compared with the 206 billion euros of bonds in private hands.

The goal of the swap, which runs until March 8, is to reduce by 53.5 percent the total of privately held Greek sovereign debt, helping the country avert an uncontrolled default.
