June 19 (Reuters) - Alliance Data Systems Corp said it agreed to acquire Bon-Ton Stores Inc's private-label credit card portfolio worth $475 million.
Financial terms of the deal were not disclosed.
Alliance Data, which provides private-label credit card services to retailers, said the acquired portfolio carried only a modest level of delinquencies.
The company does not expect the deal to add to its earnings in 2012.
Alliance Data will also manage the retailer's private-label credit card program.
