Monte Tarbox is retiring as executive director, investments, for the National Electrical Benefit Fund, Washington.
Mr. Tarbox joined the $16.1 billion NEBF 10 years ago and will retire June 30, he said in an email.
The NEBF board of trustees appointed managing director Kevin McCormack to succeed him, Mr. Tarbox said.
The NEBF, the second-largest Taft-Hartley pension plan in the U.S., is jointly administered by the International Brotherhood of Electrical Workers and the National Electrical Contractors Association.
The trustees will undertake a search to succeed Mr. McCormack as managing director of the National Electrical Annuity Plan, which has defined contribution assets of $11.8 million, he said.
