Two former executives of Western Resources Inc. together received nearly $6 million when they retired last year, according to documents filed with the federal Securities and Exchange Commission.

Carl Koupal, a former Western executive vice president who served as chief administrative officer, received a $773,378 lump-sum payment and $4.6 million in proceeds from a life insurance policy. According to Western’s 2002 proxy statement, the lump-sum payment “included amounts for accumulated but unused vacation.”

Thomas Grennan, a former executive vice president and head of Western’s utilities, received a lump-sum payment of $544,502, an unspecified portion of which also was for unused vacation time.

Grennan and Koupal also are entitled to receive reimbursements of as much as $50,000 for outplacement services and relocation expenses.
