Note 19. Commitments and Contingencies

Guarantees

In the course of selling business entities and assets to third parties, CNA has agreed to indemnify purchasers for losses arising out of breaches of representation and warranties with respect to the business entities or assets being sold, including, in certain cases, losses arising from undisclosed liabilities or certain named litigation. Such indemnification provisions generally survive for periods ranging from nine months following the applicable closing date to the expiration of the relevant statutes of limitation. As of December 31, 2011, the aggregate amount of quantifiable indemnification agreements in effect for sales of business entities, assets and third party loans was $764 million.

In addition, CNA has agreed to provide indemnification to third party purchasers for certain losses associated with sold business entities or assets that are not limited by a contractual monetary amount. As of December 31, 2011, CNA had outstanding unlimited indemnifications in connection with the sales of certain of its business entities or assets that included tax liabilities arising prior to a purchaser's ownership of an entity or asset, defects in title at the time of sale, employee claims arising prior to closing and in some cases losses arising from certain litigation and undisclosed liabilities. These indemnification agreements survive until the applicable statutes of limitation expire, or until the agreed upon contract terms expire.

Offshore Rig Purchase Obligations

Diamond Offshore has entered into three separate turnkey contracts with Hyundai Heavy Industries, Co. Ltd., ("Hyundai") for the construction of three dynamically positioned, ultra-deepwater drillships, with deliveries scheduled for the second and fourth quarters of 2013 and in the second quarter of 2014. The aggregate cost of the three drillships, including commissioning, spares and project management, is expected to be approximately $1.8 billion. The contracted price of each drillship is payable in two installments. The first installments, aggregating $478 million, were paid in 2011 and are included in Property, plant and equipment in the Consolidated Balance Sheets. The final installments of the contracted price are payable to Hyundai upon delivery of each vessel.

In December of 2011, Diamond Offshore entered into an agreement for the construction of a moored semisubmersible rig designed to operate in water depths up to 6,000 feet. The rig will be constructed utilizing the hull of one of Diamond Offshore's mid-water floaters. The upgrade is estimated to cost approximately $300 million, including commissioning, spares and project management costs.
