ATHENS, Greece (AP) — Greece has cleared a major hurdle in its race to avoid bankruptcy by persuading the vast majority of its private creditors to sign up to the biggest national debt writedown in history, paving the way for a second massive bailout.

Following weeks of intense discussions, the Greek government said Friday that 83.5 percent of private investors holding its government bonds were participating in a bond swap. Of the investors holding the euro177 billion ($234 billion) in bonds governed by Greek law, 85.8 percent joined.
