M&G Investment Management is planning to structure a collateralized debt obligation, according to an insider at the firm. The transaction, which should be ready next year, will repackage either asset-backed securities or leveraged loans, according to the insider. M&G is opting to pool these assets because they currently offer more arbitrage than high-yield and investment-grade bonds. As in the U.S., tighter corporate bond spreads have reduced the attractiveness of structuring CDOs backed by unsecured debt, causing collateral managers to use other underlying assets. M&G priced its first CDO of structured finance assets, Pallas CDO, in September. The investment management company already has two CDOs of investment-grade debt outstanding, Panther I and II, as well as a leveraged-loan CLO, Leopard I.
