Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We file income tax returns, including returns for our subsidiaries, in various jurisdictions around the world. The Internal Revenue Service ("IRS") has examined our federal income tax returns, and we have settled all issues for tax years through 2009. We participated in the IRS Compliance Assurance Program ("CAP"), which accelerates IRS examination of key transactions with the goal of resolving any issues before the taxpayer files its return, for the 2010, 2011, and 2012 tax years, and are also participating in the program for 2013. For the 2010 and 2011 tax years all but one issue, which we are appealing, has been resolved, including all matters that could affect the Company's cash tax benefits related to our spin-off in 2011 of our timeshare operations and timeshare development business. The audit for the 2012 tax year is currently ongoing. Various foreign, state, and local income tax returns are also under examination by the applicable taxing authorities. For the 2013 first quarter, we decreased our unrecognized tax benefits by $1 million from $29 million at year-end 2012 chiefly due to new information related to a federal issue and expiring statutes of limitation in several foreign jurisdictions. The unrecognized tax benefits balance of $28 million at the end of the 2013 first quarter included $13 million of tax positions that, if recognized, would impact our effective tax rate. As a large taxpayer, the IRS and other taxing authorities continually audit us. We anticipate resolving an international issue related to financing activity during the next 12 months for which we have an unrecognized tax benefit of $5 million. Although the resolution of this issue could have a significant impact on our unrecognized tax balance, we do not anticipate that it will have a material impact on our Financial Statements. On January 2, 2013, the American Taxpayer Relief Act of 2012 (the "Act") was signed into law. Some of the provisions contained in the Act were retroactive, and we recognized a $3 million benefit related to the Act in the 2013 first quarter.
