The credit union did not answer other questions about Van Rossum's departure, though his online professional profile shows that he left in June. Van Rossum did not respond to a CU Times request for comment Tuesday.

In 2016, Van Rossum's total compensation was $796,395, according to the credit union's IRS 990 form. Total compensation includes base compensation, bonuses and incentives, other reportable compensation, retirement and deferred compensation, and non-taxable benefits. SCU has not yet filed its 2017 990 form.

Van Rossum joined SCU in 2015 as a chief administration officer and served as president/CEO of the credit union's four CUSOs. Before becoming an SCU employee, he served on the cooperative's board of directors from March 1991 to March 2015.

Simmons, who received total compensation of $1.1 million in 2016, is suing SCU over a contract dispute regarding lifetime health insurance benefits for him and his wife.

Simmons alleged SCU breached two employment contracts. In the first one from 2014, SCU agreed to provide Simmons and his spouse medical, vision and dental insurance throughout the term of his presidency and thereafter until the death of both. In a second agreement dated Nov. 25, 2015, SCU allegedly agreed to provide Simmons with lifetime medical care. In this agreement, however, Sieglinde K. Simmons was not identified as Simmons' spouse.

SCU countersued Simmons for misrepresentation and breach of fiduciary duty. In addition to having an affair with a subordinate, SCU alleged in its court documents that the former CEO took her on a business trip, forgave her $38,000 loan, fired an employee who exposed the affair and lied about all of it to the board of directors.

A jury trial is scheduled for September 2019 in New Hampshire's U.S. District Court in Concord.
