According to this story by the TAB’s Jonathan Dame, the city has “refinanced a group of 2009 bonds, most of them tied to the Newton North High School reconstruction project.”

From the article: 

A lower interest rate will save the city $12.9 million over the next two decades, according to the city’s chief financial officer.

That includes roughly $1.2 million this fiscal year, $750,000 for the next two years, and $500,000 every year thereafter until 2039.

Sounds like good news to me.
