Business Combinations [Abstract]
Acquisitions and Divestitures	2. Acquisitions and Divestitures Continental Assurance Company (“CAC”) – On August 1, 2014, CNA closed the previously announced sale of the majority of its run-off annuity and pension deposit business through the sale of the common stock of CAC. The business sold, which was previously reported within the Life & Group Non-Core segment, is reported as discontinued operations in the Consolidated Condensed Statements of Income for the three and six months ended June 30, 2014 and 2013 and the assets and liabilities are presented as discontinued operations on the Consolidated Condensed Balance Sheet as of June 30, 2014. The Company has elected not to present these assets and liabilities as discontinued operations for the comparative period in the Consolidated Condensed Balance Sheets. The sales agreement included a 100% coinsurance agreement on a separate small block of annuity business outside of CAC. The assets and liabilities related to the coinsurance agreement do not qualify for discontinued operations presentation, therefore they are not reflected as discontinued operations on the Consolidated Condensed Balance Sheet as of June 30, 2014. HighMount – In May of 2014, the Company announced that HighMount Exploration & Production LLC (“HighMount”), its natural gas and oil exploration and production subsidiary, is pursuing strategic alternatives, including a potential sale of the business. In furtherance of that pursuit, the Company initiated an auction process and expects to sell HighMount, therefore the assets and liabilities of HighMount have been reclassified as discontinued operations on the Consolidated Condensed Balance Sheets as of June 30, 2014 and December 31, 2013, and are reported at estimated fair value. In the second quarter of 2014, the Company recognized an impairment charge of $259 million ($167 million after tax) related to the excess carrying value of HighMount over the estimated fair value, less costs to sell. The Company measured estimated fair value using an estimated sale price arrived at by assessing market response in the auction process in relation to valuation models provided by HighMount’s financial advisors, which are Level 3 inputs of the fair value hierarchy. The impairment charge is subject to adjustment in future periods, which could be positive or negative, reflecting the final sale price and transaction costs. The assets and liabilities of HighMount consist primarily of natural gas and oil reserves, related liabilities and long term debt. The results of operations of HighMount have been reclassified as discontinued operations in the Consolidated Condensed Statements of Income for the three and six months ended June 30, 2014 and 2013. See Note 14 for further discussion of discontinued operations. Bluegrass Project – As discussed in Note 2 of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013, Boardwalk Pipeline executed a series of agreements in 2013 with The Williams Companies, Inc. to develop the Bluegrass Project, a joint venture project that would develop a pipeline to transport natural gas liquids. The open season for capacity on the pipeline ended in the first quarter of 2014, and although discussions with potential customers continued throughout the first quarter, Boardwalk Pipeline was unable to obtain sufficient firm customer commitments to support the project. Further, delays in the development of the project and other factors have resulted in escalations in the estimated costs to complete the project. Considering these factors, the Company determined that it would no longer make capital investments in the Bluegrass Project. In the first quarter of 2014, the Company expensed the previously capitalized project costs that had been incurred, resulting in a charge of $94 million ($55 million after tax and noncontrolling interests), inclusive of a $10 million charge recorded by Boardwalk Pipeline Partners, LP. This charge was recorded within Other operating expenses on the Consolidated Condensed Statements of Income. The Company does not expect to incur significant additional charges related to this joint venture project. Loews Hotels – In 2014, Loews Hotels added three properties to its portfolio. Loews Hotels has a joint venture interest in the Cabana Bay Beach Resort, an 1,800 guestroom hotel at Universal Orlando, Florida, which opened in March of 2014. In July of 2014, Loews Hotels purchased the Loews Chicago O’Hare Hotel, a 556 guestroom hotel, and the Loews Minneapolis Hotel, a 255 guestroom hotel, for a total cost of approximately $190 million funded with a combination of cash and debt. Construction continues on the Loews Chicago Hotel, a 400 guestroom hotel, which Loews Hotels agreed to purchase upon completion of development, expected to occur in late 2014. The Loews Chicago Hotel is planned to open in early 2015.
