A notice in Florida and Virginia federal courts might signal the conclusion of about 10 years of litigation over Chinese drywall.

The joint notice for a proposed confidential settlement among Florida, Virginia and Louisiana homeowners and Chinese companies Taishan Gypsum Co. Ltd. and Beijing New Building Materials was filed in the Southern District of Florida and the Eastern District of Virginia. It notes the parties entered mediation on May 22 and 23 to resolve lawsuits over alleged financial losses and illnesses caused by sulfur emissions from drywall exported to the U.S. from China.
