Bloomberg reports PNC Financial Services Group, the second-largest U.S. regional bank, is winding down Market Street Funding LLC, a commercial-paper company it administers.

Market Street had $5.9 billion of the short-term debt outstanding as of June 30, Pittsburgh-based PNC said in a regulatory filing. The bank said it will fund Market Street’s loans and commitments “utilizing its diversified funding sources.”

The decision isn’t expected to have a material impact on PNC, the bank said.
