NEW YORK (Reuters) - Wal-Mart Stores Inc WMT.N said on Tuesday it had settled 63 class action lawsuits that accused the world's largest retailer of wage violations for at least $352 million but no more than $640 million.

The settlements, pertaining to lawsuits filed in many U.S. states, are subject to court approval. Wal-Mart said it expects a related after-tax charge from continuing operations in its fiscal fourth quarter of about $250 million, or 6 cents per share.

Wal-Mart said many of the lawsuits had been filed years ago and that the allegations did not reflect on how the company treats its more than 1 million employees today.

The company said it has agreed to use electronic systems to stay compliant with its wage and hour policies, and applicable law.

“Our policy is to pay associates for every hour worked and to provide rest and meal breaks,” Wal-Mart general counsel Tom Mars said in a statement.

The Wal-Mart statement quoted lead lawyers representing plaintiffs as saying the settlements were fair and valued the work of company employees.

Earlier this month, Wal-Mart said it would pay up to $54.3 million to settle a similar class-action lawsuit in Minnesota.
