Item 8.01 Other Events

As previously disclosed in the Company’s Quarterly Report on Form 10-Q for the quarter ended September 7, 2012, certain subsidiaries of the Company are defendants in a lawsuit in the Superior Court of California, County of San Francisco. The plaintiffs in the lawsuit, 11 residential unit owners at The Ritz-Carlton Club and Residences, San Francisco, a project within the Company’s Luxury segment, questioned the adequacy of disclosures made prior to 2008, when the Company’s business was part of Marriott International, Inc., regarding bonds issued for that project under California’s Mello-Roos Community Facilities Act of 1982 and their payment obligations with respect to such bonds. In June 2012, the trial judge issued a tentative decision on phase one of the proceedings in favor of the plaintiffs.

While the Company disagrees with the findings in the tentative decision including the theories of relief, on November 30, 2012, an agreement dated as of November 29, 2012 was entered into by the defendants and the plaintiffs to settle, without admission of liability, all claims asserted or which could have been asserted in the lawsuit. Pursuant to the settlement reached with the plaintiffs, the Company will repurchase units owned by certain of the plaintiffs at The Ritz-Carlton Club and Residences, San Francisco.

Two other lawsuits are pending in which 11 other owners at the same property assert similar claims. The two other lawsuits are distinct from the settled lawsuit, and the Company believes that it has defenses with respect to the claims asserted in such lawsuits and intends to vigorously defend against them.

As a result of the settlement, the Company expects to record a charge of $25 million to $40 million in the quarter ended December 28, 2012 with respect to the settlement and to increase the existing accrual for the two remaining lawsuits. While the Company believes that the accrual will be adequate, depending on the outcome, the Company may be required to record additional charges in connection with these matters.
