A buyer may be close to purchasing SEI Capital Resources, the consulting division of SEI Corp. Officials of the parent company postponed a meeting with analysts scheduled for next Wednesday, saying negotiations with a buyer were progressing at a very fast pace. The meeting was postponed until Nov. 29. Johnson & Higgins, New York, might conduct an asset allocation study on its $70 million in non-qualified benefit plans in the next two months, according to Terry Lett, cash manager. The plans are invested in domestic stocks, municipal bonds and international stocks. Consultant A. Foster Higgins, a subsidiary of Johnson & Higgins, would be involved in the process. It has not been determined whether an outside consultant also would be used. No changes are planned for the qualified plans, which include a $560 million savings plan and a $340 million pension plan, he said. Bell Atlantic Corp., Philadelphia, will convert its management employees' pension plan to a cash balance plan, effective Jan. 1. It covers 15,000 employees, and is part of a $12 billion master trust. Barry Simko, director of benefits planning and human resource communication, said the change is being made ``to meet the needs of mobile employees, who make more frequent moves from employer to employer.'' The Bell Atlantic cash balance plan will include a feature allowing employees to receive a part of their accrued benefit as a lump sum and the rest as an annuity. William M. Mercer Inc. was the consultant. Decisions on the management of the assets have not yet been made. Advent International seeks to raise $200 million from institutional investors, primarily in the United States, for a Latin American Private Equity Fund, said CEO Douglas Brown. The fund will invest in management buy-outs and expansion financing. Officials hope to raise 50% to 70% of the total by the fund's first closing, near year end. A provision in the Republican tax package that would let companies tap surplus pension fund assets over the next five years could become permanent, predicts a key congressional committee staffer. That change would result in billions of dollars leaking from the private pension system. ``This is the beginning. The right thing to do would be to make it permanent,'' said Ken Kies, chief of staff on the Joint Committee of Taxation, which prepared the cost estimates for the Republican budget package in both chambers. A new investment fund that aims to deliver capital to South Africa's most economically depressed communities was launched today. The Thembani International Guarantee Fund is a joint venture between its U.S. sponsor, Shared Interest, and a Swiss development organization called RAFAD, Research and Applications of Alternative Finance for Development. Shared Interest will raise money in the United States; RAFAD will raise money in Europe. The money raised, expected to total $10 million over five years, will guarantee loans issued by South African banks to community development institutions for very small businesses and housing. The money will be deposited in U.S. community banks and U.S. government securities. Investors will get a below market return of about 3% per year, according to Donna Katzin, executive director. The likely candidates: religious organizations, foundations, individuals and perhaps some corporations.
