The transaction is subject to normal and customary closing conditions.  Terms of the transaction were not disclosed.

Based in Lake Forest, Calif., with operations in Dallas, Portfolio is a leading independent provider of finance and insurance products and services to automotive dealers across the country, including vehicle service contracts, GAP and ancillary products, and specializes in managing affiliated reinsurance companies for dealership owners.

Brent Stone, a senior partner at Abry, said, “We have been impressed by Portfolio’s growth with consistent profitability over the years in a very competitive industry, as well as the quality of their home office and sales leadership in the field. The Portfolio team is a perfect example of the kind of company we invest in — motivated owners and executives who want to grow. We look forward to providing them the resources to help them succeed, while providing long-term value for all stakeholders in this investment.”
