Mitsubishi UFJ Securities Co. said Monday it will provide merger and acquisition advisory services in collaboration with an investment-banking boutique recently set up by the famous U.S. investment banker Joseph Perella.

In addition to the alliance, Mitsubishi UFJ Securities, the core brokerage of Mitsubishi UFJ Financial Group, will provide $100 million to Perella's firm and its investment fund.

The company will offer advisory and asset management services. Perella is former vice chairman of Morgan Stanley.

Capitalizing on Mitsubishi UFJ Securities's abundant clients and Perella's investment banking expertise and personal connections, the two will jointly provide advisory services for cross-border M&As between Japanese and U.S.-European companies.

"Our respective firms' businesses are strategically and geographically complementary and we look forward to working with our new partner to provide superior products to the clients of both firms," Perella said in a statement.
