Citibank is said to be shopping a portfolio of loans that is worth about $115 million and contains about 47 names. One loan investor said the average spread of the portfolio is LIBOR plus 290 basis points. The portfolio is said to contain a staple of flow names such as Allied Waste Industries, Alaris Medical Systems and Charter Communications. There are also said to be a couple of stressed names in the portfolio. Traders at Citi did not return calls by press time and it could not be ascertained if the portfolio was assembled by Citibank or whether it is a deal being liquidated by another portfolio manager. Several loan investors commented that Citibank has been at the forefront of creating portfolio auctions, with the end buyers being prime-rate and closed-end funds. But one loan investor said dealer-to-dealer auctions are also not unheard of.
