Koch unit Georgia-Pacific used a corporate bankruptcy maneuver known as the Texas two-step, forming a new Texas subsidiary, Bestwall, that took on the company's asbestos liability.
The latest court documents, filed on Wednesday, provide new detail about how Koch has benefited from the case.
Koch has received more than $5 billion since Bestwall filed for bankruptcy in 2017.
Representatives for New Georgia-Pacific and Koch Industries did not immediately respond to a request for comment on Thursday.
New Georgia-Pacific's shareholder equity is forecast to be about $27.8 billion after accounting for the Koch dividends, according to the Wednesday court filing.
