LOS ANGELES — The Mashantucket Pequot Tribal Nation, owner of the Foxwoods Resort Casino in Connecticut, reached a preliminary agreement with lenders to restructure $2.2 billion in debt.

The accord lowers the debt balance and extends maturities at favorable rates, Foxwoods chief executive Scott Butera said. The tribe will work with lenders and bondholders to build support for the agreement over the next several months.

“This represents a critical step forward for our business,” Butera said.
