JP Morgan has sold a large portfolio of loans to an affiliate of Bain & Co, the firms said in a deal not expected to materially affect the US firm's earnings.

Sankaty Advisors, a managed credit affiliate of Bain Capital, has agreed to acquire a $1.3 billion portfolio of loans and other securities from JP Morgan's Global Special Opportunities Group.

The portfolio contains mezzanine loans in North America and Europe, as well as loans and related special situations investments in Australia and across Asia, Sankaty said in a statement yesterday. The definitive purchase agreement follows Sankaty Advisors' other purchases of loan portfolios from Irish Bank Resolution Capital, Lloyds Banking Group and CapitalSource, it said.

The transaction, which is expected to close by the end of 2014, is subject to borrower and regulatory approvals. Kirkland & Ellis served as legal counsel to Sankaty Advisors. JP Morgan advised on the sale and Davis Polk & Wardwell, served as legal counsel to JPMorgan Chase.

This transaction is not expected to have a material impact on JP Morgan's earnings.
