MINNEAPOLIS — Target Corp. has reached a $19 million settlement with MasterCard that is a big step toward resolving pending claims from banks and credit unions over losses from the retailer’s massive 2013 data breach.

Card-issuing institutions spent millions to replace cards and cover fraudulent transactions after the breach, in which hackers accessed card or personal information from as many as 110 million people.

The deal the Minneapolis-based retailer and MasterCard announced Wednesday is contingent on approval from those banks. At least 90 percent of the eligible MasterCard accounts would need to release both entities from any other claims, including a class-action lawsuit against Target brought by banks that is pending in federal court in St. Paul.

The proposed settlement does not include Visa. A Target spokesman said he had no update to share on the retailer’s negotiations with Visa.

The proposed $19 million settlement is already included in the $252 million in costs Target has said it expects to pay in the aftermath of one of the largest retail data breaches during the holiday shopping season in 2013. About 40 million customers had their payment card information stolen after hackers infiltrated Target’s point-of-sale systems. Another 70 million people had their personal information swiped, too.
