Home Request Documents FAQ Contact Info


If you purchased Oriented Strand Board ("OSB") for your own use, not for resale, between
June 1, 2002 andAugust 4, 2008, your rights may be affected by five class action settlements.

The United States District Court for the Eastern District of Pennsylvania authorized this notice.

What is the lawsuit about?

The lawsuit claims that certain manufacturers of Oriented Strand Board ("OSB") unlawfully raised the prices paid by end user indirect purchasers of OSB.  OSB is an engineered wood product used in construction, roofing, flooring and other applications. You are an indirect purchaser if you bought OSB for your use, and not for resale, from a store or reseller and not directly from the manufacturer.  The lawsuit, which has been vigorously litigated for over two years, seeks damages, injunctive relief, attorneys' fees and costs from the manufacturers.  Defendants deny that their conduct was unlawful in any respect.  The Court has not ruled on the merits of these claims.

Who's Included?

The Court has certified a settlement class (the "Settlement Class") consisting of all persons and entities in the United States who, as end users, indirectly purchased for their own use, and not for resale, new OSB manufactured and sold by one or more of the following manufacturers from June 1, 2002 through August 4, 2008: Louisiana-Pacific Corporation ("LP"), Weyerhaeuser Company ("Weyerhaeuser"), Georgia-Pacific LLC f/k/a Georgia-Pacific Corp. ("Georgia-Pacific"), Potlatch Corporation ("Potlatch"), Ainsworth Lumber Co. Ltd. ("Ainsworth"), Norbord Industries Inc. ("Norbord"), Tolko Industries Ltd. ("Tolko"), J.M. Huber Corp. and Huber Engineered Woods LLC ("Huber").

If you purchased a completed home or other structure from a builder or contractor or if you had a home renovation project done for you by a builder or contractor, using OSB, but you cannot separately identify and document your OSB purchases, you are not a member of the Settlement Class.

A complete description of the Settlement Class is included in a Detailed Notice, available at or by calling toll free 1-800-401-0819.

What do the Settlements Provide?

To resolve the litigation, LP agreed to pay $2,300,000, Norbord agreed to pay $2,200,000, Weyerhaeuser agreed to pay $1,440,000, Tolko agreed to pay $350,000, and Potlatch agreed to pay $300,000.  Settlement Agreements with these five manufacturers, available at the website above, describe all of the details about the proposed settlements.  Three previous settlements with Defendants Georgia-Pacific, Ainsworth and Huber totaling $3,350,000 have already been approved by the Court.  The total settlement fund created by all eight settlements is $9,940,000.  Of that amount, $1,000,000 will be distributed from the settlement fund to one or more charitable or non-profit organizations, including Rebuilding Together, or as otherwise directed by the Court.  Residents of the District of Columbia, Arizona, California, Florida, Iowa, Kansas, Maine,  Massachusetts, Michigan, Minnesota, Mississippi, Nevada, New Mexico, New York, North Carolina, North Dakota, South Dakota, Tennessee, Vermont, West Virginia and Wisconsin, may make claims for money from the settlement fund (after payment of various costs including attorneys' fees, out-of-pocket expenses, and the costs of notice and claims administration).  However, please be aware that if you remain in the Settlement Class, you will be releasing your claims against LP, Norbord, Weyerhaeuser, Tolko and Potlatch whether or not you ultimately are entitled to any money from the settlement fund.  Class Counsel believe that the settlements are fair, reasonable and adequate in light of the substantial risks associated with continued litigation. Class Counsel will request attorneys' fees not to exceed one-third of the total settlement funds paid by all of the Defendants, including from the three previous settlements, in addition to incentive awards for the class representatives and reimbursement of out-of-pocket expenses.
