Dow Chemical Co. and the DuPont Co. have agreed to pay Dow's lame-duck CEO, Andrew Liveris, $52.8 million in cash, stock and tax reimbursement payments if he leaves on schedule in 2017, and another $27 million to DuPont CEO Edward Breen if Breen, Liveris' partner in the companies' merger and break-up plan, leaves the company by early 2017, the companies said in this SEC filing.

The executives have assembled these multimillion-dollar pay packages, which the SEC-mandated report calls "Golden Parachutes," while planning and executing billions of dollars in cost cuts and mass layoffs, including 1,700 research scientists, technicians, lawyers, corporate managers and other central staff in Delaware, where DuPont is headquartered. The filing noted Breen has also piled up DuPont stock options worth $7 million, which could be worth much more if his merger and breakup plan succeeds in significantly boosting share values.

The filing notes Liveris would have gotten all but $13 million of the total even without the merger, after running Dow for a decade.

The document also details how Breen's predecessor, Ellen Kullman, launched merger talks with Dow back in November 2014, six months before she narrowly beat back an insurgent Board of Directors challenge led by hedge fund boss Nelson Peltz, who Kullman supporters had denounced for supporting accelerated cost cuts; and that Breen continued the Dow talks Kullman started after he took over as CEO in October 2015. Along the way DuPont discussed possible merger with at least one other company, whom it doesn't identify.

While planning their reorganization, DuPont and Dow said they have each "received a request for additional information and documentary materials from the (United States Department of Justice) Antitrust Division regarding the mergers," which could delay the deal, which they hope to conclude this fall before splitting the merged corporation into pesticide, materials and performance-materials companies over the following two years. The companies say they expected the request, will "respond promptly," and pledged they will cooperate with the competition cops.  

CORRECTED: Separately, DuPont says it has hired former US Department of Agriculture Krysta Harden as its new Vice President of Public Policy and Chief Sustainability Officer. She replaces Linda Fisher, who held the job since 2004 and was, DuPont says, the first such office at a major company. "She'll have a full plate," Turner said, when asked if Harden's government experience was especially important as the company combines its ag operations and faces antitrust scrutiny. (An earlier version of this item inaccurately conflated Harden's and Fisher's past careers.)
