STILL NEGOTIATING: Disagreements remain between Greece and its private creditors on cutting the country's massive debt load. They're divided on financial questions that will determine the level of investor losses.

KEY DEAL: The eurozone and bank representatives reached a tentative deal on a debt restructuring in late October to help Greece cut its debts by about 100 billion euros (around $130 billion). Discussions on the details of the agreement, which Greece needs to receive a necessary second aid package, have dragged on.

BACKGROUND: Greece is being kept afloat with low-cost loans from the eurozone and the International Monetary Fund.
