ST. PAUL, Minn. (AP) - Officials from the state's health exchange say they're on track to meet a crucial enrollment goal.

MNsure announced Monday it had signed up roughly 31,000 Minnesotans in private plans ahead of the Dec. 31 deadline for coverage effective Jan. 1. That's less than half of their goal of 67,000 such signups in 2015.

But MNsure spokesman Joe Campbell says the exchange is in good shape to meet that target because open enrollment lasts through Feb. 15.

Campbell says they signed up about 40 percent of their customers in the last month of enrollment last year.

Industry experts have worried the exchange isn't on track to meet its enrollment targets. Those numbers are crucial because MNsure takes a fee off private plans to fund its operations.
