MARTA expects to save more than a $1 million a year through a handful of debt restucturing moves it has taken over the past few months.

The agency plans to convert $100 million in variable rate bonds from an interest rate that changes every week to one that changes every month, said Treasurer Kevin Hurley Friday.

That transaction is projected to save the agency about $300,000 a year. Two other bond restructures should save the agency about $750,000, Hurley said.

"We're looking under every rock and trying to do everything we can to cut costs, including looking at all the financial instruments we have in place," Hurley said.
