Commitments and Contingencies	Commitments and Contingencies Guaranteed Maximum Price Agreement for L'Auberge Baton Rouge: On April 5, 2010, we entered into an Agreement for Guaranteed Maximum Price Construction Services with a general contractor for the construction of L'Auberge Baton Rouge. In May 2011, we entered into an amendment to the agreement, which, among other things, provides that the contractor will complete the construction of the casino for the total guaranteed maximum price of approximately $229 million, and currently provides for a guaranteed date of substantial completion of May 31, 2012, which we expect to amend for a later date. We expect L'Auberge Baton Rouge to open by Labor Day 2012. The guaranteed maximum price set by the amendment to the agreement is a portion of the total budget for the project. Due to construction disruption and previously unanticipated site preparation work, we expect the construction budget to increase by up to 3.0% to $368 million from the prior budget of $357 million. Redevelopment Agreement: In connection with our Lumière Place Casino and Hotel ("Lumière Place"), we have a redevelopment agreement which, among other things, commits us to oversee the investment of $50.0 million in residential housing, retail or mixed-use developments in the City of St. Louis within five years of the opening of Lumière Place. Such investment can be made with partners and partner contributions and project debt financing, all of which count toward the $50.0 million investment commitment. To date, we have invested or committed in partnership with other parties certain projects the provide us with approximately$13 million in credits toward investments under the redevelopment agreement. The redevelopment agreement also contains certain contingent payments in the event of certain defaults. If we and any development partners collectively fail to invest $50.0 million in residential housing, retail, or mixed-use developments within five years of the opening of the casino and hotels, we would be obligated to pay a service fee of $1.0 million, less applicable credits, in year six and $2.0 million annually thereafter, adjusted by the change in the consumer price index. In addition, we are also obligated to pay an annual fee of $1.0 million to the City of St. Louis, which obligation began after our River City Casino opened in March 2010. Lease and Development Agreement for River City Casino: In connection with our River City Casino, we have a lease and development agreement with the St. Louis County Port Authority, which, among other things, commits us to lease 56 acres for 99 years (subject to certain termination provisions). We have invested the minimum requirement of $375 million, pursuant to the agreement. From April 1, 2010 through the expiration of the term of the lease and development agreement, we are required to pay to St. Louis County as annual rent the greater of (a) $4.0 million, or (b) 2.5% of annual adjusted gross receipts, as that term is defined in the lease and development agreement. We are also required to invest an additional $75 million in the second phase of the project to construct: (a) a hotel with a minimum of 200 guestrooms, (b) a meeting room/event space with at least 10,000 square feet, and (c) a parking garage with a minimum of 1,600 parking spaces. We are required to achieve substantial completion of the second phase by October 31, 2013. In the event the second phase is not substantially complete by October 31, 2013, we are required to pay liquidated damages of $2.0 million beginning on November 1, 2013. In each subsequent year that the second phase is not opened, the amount of liquidated damages increases by $1.0 million, hence, $3.0 million in 2014, $4.0 million in 2015, $5.0 million in 2016 and $6.0 million in 2017. As a result, the maximum amount of liquidated damages that we would have to pay if the second phase is not completed is $20.0 million. Self-Insurance: We self-insure various levels of general liability and workers' compensation at all of our properties and medical coverage at most of our properties. Insurance reserves include accruals for estimated settlements for known claims, as well as accruals for estimates of claims not yet made. At December 31, 2011 and 2010, we had total self-insurance accruals of $14.8 million and $16.9 million, respectively, which are included in “Other accrued liabilities” in our Consolidated Balance Sheets. Indiana Tax Dispute: In 2008, the Indiana Department of Revenue (“IDR”) commenced an income tax examination of the Company's Indiana income tax filings for the 2005 to 2007 period. In February 2010, the Company received a notice of proposed adjustment from the field agent in the amount of $7.3 million, excluding interest and penalties of $2.3 million, challenging the treatment of income and gain from certain asset sales outside of Indiana, which we reported on our Indiana state tax returns for the years 2000 through 2007. In March 2010, the Company timely filed a protest with the IDR requesting abatement of all tax, interest and penalties. In September 2010, a hearing was held with the IDR where the Company restated significant facts and positions which the Company believed the field agent had not taken into consideration in issuing the assessment. On March 30, 2011, the IDR issued a letter of finding which denied all issues protested in the hearing, but sustained the Company's request to waive penalties. On April 28, 2011, the Company timely filed a rehearing request of which the IDR promptly granted. A rehearing was conducted on June 22, 2011, with the Company presenting additional clarifying facts and technical support for our tax positions. The IDR has 60 days to review the additional data presented and will issue its supplemental findings. As of the date of these financial statements, the Company is still awaiting the issuance of the supplemental findings. Redemption of Securities Owned By an Unsuitable Person: Our certificate of incorporation grants us the power to redeem our securities or the securities of our affiliated companies from a person who owns or controls these securities if: (a) that person is determined by a governmental gaming authority to be unsuitable to own or control these securities, or (b) that person causes us or any of our affiliated companies to lose or be threatened with the loss of any gaming license or, in the sole discretion of our Board of Directors, that person is deemed likely to jeopardize our right to conduct gaming activities in any of the jurisdictions in which we conduct gaming activities. Under the foregoing circumstances, we may redeem, and may be required by the applicable gaming authority, to redeem, that person's securities to the extent required by the gaming authority or deemed necessary or advisable by us. The redemption price will be determined by the gaming authority or otherwise will be a price deemed reasonable by us, which in our discretion could be the original purchase price or the then current trading price of the securities. Furthermore, we may pay the redemption price in cash, by promissory note, or both, as required by the gaming authority or otherwise as we elect. Other: We are a party to a number of pending legal proceedings. Management does not expect that the outcome of such proceedings, either individually or in the aggregate, will have a material effect on our financial position, cash flows or results of operations.
