Commitments And Contingencies [Abstract]
Commitments And Contingencies	NOTE 17—COMMITMENTS AND CONTINGENCIES Legal Proceedings The Company records an accrual for legal contingencies to the extent that it concludes that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Except as disclosed below, no estimate of the possible loss or range of loss in excess of amounts accrued, if any, can be made at this time regarding the matters specifically described below. We do not believe that the final outcome of these matters will have a material adverse impact on our business, financial condition and results of operations. Horse Racing Equity Trust Fund During 2006, the Illinois General Assembly enacted Public Act 94-804, which created the Horse Racing Equity Trust Fund ("HRE Trust Fund"). During November 2008, the Illinois General Assembly passed Public Act 95-1008 to extend Public Act 94-804 for a period of three years beginning December 12, 2008. The HRE Trust Fund was funded by a 3% "surcharge" on revenues of Illinois riverboat casinos that met a certain revenue threshold. The riverboats paid all monies required under Public Acts 94-804 and 95-1008 into a special protest fund account which prevented the monies from being transferred to the HRE Trust Fund. The funds were moved to the HRE Trust Fund and distributed to the racetracks, including Arlington Park, in December 2009. On June 12, 2009, the riverboat casinos filed a lawsuit in the United States District Court for the Northern District of Illinois, Eastern Division, against former Governor Rod Blagojevich, Friends of Blagojevich and others, including Arlington Park (Empress Casino Joliet Corp. v. Blagojevich, 2009 CV 03585). While the riverboat casinos alleged violations of the Racketeer Influenced and Corrupt Organizations Act ("RICO") against certain of the defendants, Arlington Park was not named in the RICO count, but rather was named solely in a count requesting that the monies paid by the riverboat casinos pursuant to Public Acts 94-804 and 95-1008 be held in a constructive trust for the riverboat casinos' benefit and ultimately returned to the casinos. The defendants moved to dismiss the complaint, and the plaintiffs moved for a preliminary injunction seeking to prevent distribution of the disputed funds from the HRE Trust Fund to the racetrack defendants, including Arlington Park. On November 20, 2009, the trial court entered a temporary restraining order ("TRO") requiring that any funds distributed from the HRE Trust Fund to the racetrack defendants be placed in a special interest-bearing escrow account separate and apart from other monies. On December 7, 2009, the trial court dismissed the constructive trust count of the complaint and denied the plaintiffs' motion for a preliminary injunction. The plaintiffs appealed, and the court of appeals stayed dissolution of the TRO pending the appeal. On March 2, 2011, a three member panel of the Seventh Circuit Court of Appeals reversed the trial court's dismissal. We requested the Seventh Circuit Court of Appeals to rehear the matter en banc and, on April 11, 2011, the Appellate Court issued an order to rehear the matter en banc. That hearing was held on May 10, 2011. On July 8, 2011, the Seventh Circuit Court of Appeals issued a thirty-day stay of dissolution of the TRO to allow the casinos to request a further stay of dissolution of the TRO pending their petition for certiorari to the United States Supreme Court. On August 5, 2011, the United States Supreme Court denied an application by the Casinos to further stay the dissolution of the TRO. On August 9, 2011, the stay of dissolution expired and the TRO dissolved, which terminated the restrictions on the Company's ability to access funds from the HRE Trust Fund held in the escrow account. Public Act 94-804 expired in May 2008 and Public Act 95-1008 expired on July 18, 2011, the date the tenth Illinois riverboat license became operational. Arlington Park filed an administrative appeal in the Circuit Court of Cook County on August 18, 2009 (Arlington Park Racecourse LLC v. Illinois Racing Board, 09 CH 28774), challenging the IRB allocation of funds out of the HRE Trust Fund based upon handle generated by certain ineligible licensees, as contrary to the language of the statute. The Circuit Court affirmed the IRB's decision on November 10, 2010, and Arlington appealed this ruling to the Illinois First District Court of Appeals. The briefing on this appeal was completed during December 2011, and the parties are awaiting either a ruling or a notice that the appellate court will schedule oral arguments. Hawthorne Racecourse filed a separate administrative appeal on June 11, 2010 (Hawthorne Racecourse, Inc. v. Illinois Racing Board et. al., Case No. 10 CH 24439), challenging the IRB's decision not to credit Hawthorne with handle previously generated by an ineligible licensee for the purpose of calculating the allocation of the HRE Trust Fund monies and the IRB's unwillingness to hold another meeting in 2010 to reconstrue the statutory language in Public Act 95-1008 with respect to distributions. On May 25, 2011, the Circuit Court rejected Hawthorne's arguments and affirmed the IRB's decisions, and Hawthorne appealed the Circuit Court's decision. Hawthorne initially asked the court to stay the further distribution of HRE Trust Fund monies pending the outcome of the appeal. The parties are currently briefing Hawthorne's appeal. We have received $45.4 million from the HRE Trust Fund, of which $26.1 million has been designated for Arlington Park purses. We intend to use the remaining $19.3 million of the proceeds to improve, market, and maintain or otherwise operate the Arlington Park racing facility in order to conduct live racing. The trial court had originally ordered the State of Illinois to pay interest on the funds held in the special protest fund. The appellate court overturned this order and the Illinois Supreme Court declined to reconsider the appellate court's decisions. As a result, the State of Illinois is not obligated to pay interest on these funds. The deadline for the casino plaintiffs to file a petition for certiorari has lapsed and, as a result, we believe that this litigation is final with respect to Arlington Park. Hialeah Race Course On February 14, 2011, Hialeah Race Course ("Hialeah") filed a lawsuit styled Hialeah Racing Association, South Florida Racing Association, LLC and Bal Bay Realty, LTD vs. West Flagler Associates, LTD, Calder Race Course, Inc. and Tropical Park, Inc. (Case No. 11-04617 CA24) in the Circuit Court of the Eleventh Judicial Circuit in and for Miami-Dade County, Florida. The plaintiffs allege that the defendants, including Calder and Tropical Park, have engaged in unfair methods of competition and have committed unfair acts and practices by, among other things, engaging in concerted actions designed to prevent the enactment of legislation to regulate thoroughbred racing dates, coordinating the selection of racing dates among Calder, Tropical Park and Gulfstream Park, soliciting the revocation of Hialeah's racing permit which prevented Hialeah from operating, participating in the drafting of a Florida constitutional amendment on slot machines to ensure that Hialeah was excluded from obtaining the opportunity to conduct gaming under such a constitutional amendment and instituting litigation challenging the validity of certain legislation in an effort to prevent the operation of slot machines at Hialeah. The plaintiffs have alleged an unspecified amount in damages. Motions to dismiss on behalf of Calder and Tropical Park were served on March 14, 2011, and March 21, 2011, respectively. Discovery in this case has been stayed pending the resolution of another case involving these parties currently being appealed to the Florida Supreme Court. Balmoral, Maywood and Illinois Harness Horsemen's Association On February 14, 2011, Balmoral Racing Club, Inc., Maywood Park Trotting Association, Inc. and the Illinois Harness Horsemen's Association, Inc. filed a lawsuit styled Balmoral Racing Club, Inc., Maywood Park Trotting Association, Inc. and the Illinois Harness Horsemen's Association Inc. vs. Churchill Downs Incorporated, Churchill Downs Technology Initiatives Company d/b/a TwinSpires.com and Youbet.com, LLC (Case No. 11-CV-D1028) in the United States District Court for the Northern District of Illinois, Eastern Division. The plaintiffs allege that Youbet.com breached a co-branding agreement dated December 2007, as amended on December 21, 2007, and September 26, 2008 (the "Agreement"), which was entered into between certain Illinois racetracks and a predecessor of Youbet.com. The plaintiffs allege that the defendants breached the agreement by virtue of an unauthorized assignment of the Agreement to TwinSpires.com and further allege that Youbet.com and TwinSpires have misappropriated trade secrets in violation of the Illinois Trade Secrets Act. Finally, the plaintiffs allege that the Company and TwinSpires.com tortiously interfered with the Agreement by causing Youbet.com to breach the Agreement. The plaintiffs have alleged damages of at least $3.6 million, or alternatively, of at least $0.8 million. On April 1, 2011, the plaintiffs filed a motion for a preliminary injunction, seeking an order compelling the defendants to turn over all Illinois customer accounts and prohibiting TwinSpires.com from using that list of Illinois customer accounts. On April 18, 2011, the defendants filed an answer and a motion to dismiss certain counts of the plaintiffs' complaint, and Youbet.com asserted a counterclaim seeking certain declaratory relief relating to allegations that plaintiffs Maywood and Balmoral breached the Agreement in 2010, leading to its proper termination by Youbet.com on December 1, 2010. The preliminary injunction hearing took place on July 6, 2011, and on July 21, 2011, the court denied the preliminary injunction. The parties remain engaged in the discovery process, and mediation is scheduled for March 2012. There are no other material pending legal proceedings, other than litigation arising in the ordinary course of our business.

NOTE 17—COMMITMENTS AND CONTINGENCIES

Legal Proceedings

The Company records an accrual for legal contingencies to the extent that it concludes that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Except as disclosed below, no estimate of the possible loss or range of loss in excess of amounts accrued, if any, can be made at this time regarding the matters specifically described below. We do not believe that the final outcome of these matters will have a material adverse impact on our business, financial condition and results of operations.

Horse Racing Equity Trust Fund

During 2006, the Illinois General Assembly enacted Public Act 94-804, which created the Horse Racing Equity Trust Fund ("HRE Trust Fund"). During November 2008, the Illinois General Assembly passed Public Act 95-1008 to extend Public Act 94-804 for a period of three years beginning December 12, 2008. The HRE Trust Fund was funded by a 3% "surcharge" on revenues of Illinois riverboat casinos that met a certain revenue threshold. The riverboats paid all monies required under Public Acts 94-804 and 95-1008 into a special protest fund account which prevented the monies from being transferred to the HRE Trust Fund. The funds were moved to the HRE Trust Fund and distributed to the racetracks, including Arlington Park, in December 2009.

On June 12, 2009, the riverboat casinos filed a lawsuit in the United States District Court for the Northern District of Illinois, Eastern Division, against former Governor Rod Blagojevich, Friends of Blagojevich and others, including Arlington Park (Empress Casino Joliet Corp. v. Blagojevich, 2009 CV 03585). While the riverboat casinos alleged violations of the Racketeer Influenced and Corrupt Organizations Act ("RICO") against certain of the defendants, Arlington Park was not named in the RICO count, but rather was named solely in a count requesting that the monies paid by the riverboat casinos pursuant to Public Acts 94-804 and 95-1008 be held in a constructive trust for the riverboat casinos' benefit and ultimately returned to the casinos. The defendants moved to dismiss the complaint, and the plaintiffs moved for a preliminary injunction seeking to prevent distribution of the disputed funds from the HRE Trust Fund to the racetrack defendants, including Arlington Park. On November 20, 2009, the trial court entered a temporary restraining order ("TRO") requiring that any funds distributed from the HRE Trust Fund to the racetrack defendants be placed in a special interest-bearing escrow account separate and apart from other monies. On December 7, 2009, the trial court dismissed the constructive trust count of the complaint and denied the plaintiffs' motion for a preliminary injunction. The plaintiffs appealed, and the court of appeals stayed dissolution of the TRO pending the appeal. On March 2, 2011, a three member panel of the Seventh Circuit Court of Appeals reversed the trial court's dismissal. We requested the Seventh Circuit Court of Appeals to rehear the matter en banc and, on April 11, 2011, the Appellate Court issued an order to rehear the matter en banc. That hearing was held on May 10, 2011. On July 8, 2011, the Seventh Circuit Court of Appeals issued a thirty-day stay of dissolution of the TRO to allow the casinos to request a further stay of dissolution of the TRO pending their petition for certiorari to the United States Supreme Court. On August 5, 2011, the United States Supreme Court denied an application by the Casinos to further stay the dissolution of the TRO. On August 9, 2011, the stay of dissolution expired and the TRO dissolved, which terminated the restrictions on the Company's ability to access funds from the HRE Trust Fund held in the escrow account. Public Act 94-804 expired in May 2008 and Public Act 95-1008 expired on July 18, 2011, the date the tenth Illinois riverboat license became operational.

Arlington Park filed an administrative appeal in the Circuit Court of Cook County on August 18, 2009 (Arlington Park Racecourse LLC v. Illinois Racing Board, 09 CH 28774), challenging the IRB allocation of funds out of the HRE Trust Fund based upon handle generated by certain ineligible licensees, as contrary to the language of the statute. The Circuit Court affirmed the IRB's decision on November 10, 2010, and Arlington appealed this ruling to the Illinois First District Court of Appeals. The briefing on this appeal was completed during December 2011, and the parties are awaiting either a ruling or a notice that the appellate court will schedule oral arguments. Hawthorne Racecourse filed a separate administrative appeal on June 11, 2010 (Hawthorne Racecourse, Inc. v. Illinois Racing Board et. al., Case No. 10 CH 24439), challenging the IRB's decision not to credit Hawthorne with handle previously generated by an ineligible licensee for the purpose of calculating the allocation of the HRE Trust Fund monies and the IRB's unwillingness to hold another meeting in 2010 to reconstrue the statutory language in Public Act 95-1008 with respect to distributions. On May 25, 2011, the Circuit Court rejected Hawthorne's arguments and affirmed the IRB's decisions, and Hawthorne appealed the Circuit Court's decision. Hawthorne initially asked the court to stay the further distribution of HRE Trust Fund monies pending the outcome of the appeal. The parties are currently briefing Hawthorne's appeal.

We have received $45.4 million from the HRE Trust Fund, of which $26.1 million has been designated for Arlington Park purses. We intend to use the remaining $19.3 million of the proceeds to improve, market, and maintain or otherwise operate the Arlington Park racing facility in order to conduct live racing. The trial court had originally ordered the State of Illinois to pay interest on the funds held in the special protest fund. The appellate court overturned this order and the Illinois Supreme Court declined to reconsider the appellate court's decisions. As a result, the State of Illinois is not obligated to pay interest on these funds. The deadline for the casino plaintiffs to file a petition for certiorari has lapsed and, as a result, we believe that this litigation is final with respect to Arlington Park.

Hialeah Race Course

On February 14, 2011, Hialeah Race Course ("Hialeah") filed a lawsuit styled Hialeah Racing Association, South Florida Racing Association, LLC and Bal Bay Realty, LTD vs. West Flagler Associates, LTD, Calder Race Course, Inc. and Tropical Park, Inc. (Case No. 11-04617 CA24) in the Circuit Court of the Eleventh Judicial Circuit in and for Miami-Dade County, Florida. The plaintiffs allege that the defendants, including Calder and Tropical Park, have engaged in unfair methods of competition and have committed unfair acts and practices by, among other things, engaging in concerted actions designed to prevent the enactment of legislation to regulate thoroughbred racing dates, coordinating the selection of racing dates among Calder, Tropical Park and Gulfstream Park, soliciting the revocation of Hialeah's racing permit which prevented Hialeah from operating, participating in the drafting of a Florida constitutional amendment on slot machines to ensure that Hialeah was excluded from obtaining the opportunity to conduct gaming under such a constitutional amendment and instituting litigation challenging the validity of certain legislation in an effort to prevent the operation of slot machines at Hialeah. The plaintiffs have alleged an unspecified amount in damages. Motions to dismiss on behalf of Calder and Tropical Park were served on March 14, 2011, and March 21, 2011, respectively. Discovery in this case has been stayed pending the resolution of another case involving these parties currently being appealed to the Florida Supreme Court.

Balmoral, Maywood and Illinois Harness Horsemen's Association

On February 14, 2011, Balmoral Racing Club, Inc., Maywood Park Trotting Association, Inc. and the Illinois Harness Horsemen's Association, Inc. filed a lawsuit styled Balmoral Racing Club, Inc., Maywood Park Trotting Association, Inc. and the Illinois Harness Horsemen's Association Inc. vs. Churchill Downs Incorporated, Churchill Downs Technology Initiatives Company d/b/a TwinSpires.com and Youbet.com, LLC (Case No. 11-CV-D1028) in the United States District Court for the Northern District of Illinois, Eastern Division. The plaintiffs allege that Youbet.com breached a co-branding agreement dated December 2007, as amended on December 21, 2007, and September 26, 2008 (the "Agreement"), which was entered into between certain Illinois racetracks and a predecessor of Youbet.com. The plaintiffs allege that the defendants breached the agreement by virtue of an unauthorized assignment of the Agreement to TwinSpires.com and further allege that Youbet.com and TwinSpires have misappropriated trade secrets in violation of the Illinois Trade Secrets Act. Finally, the plaintiffs allege that the Company and TwinSpires.com tortiously interfered with the Agreement by causing Youbet.com to breach the Agreement. The plaintiffs have alleged damages of at least $3.6 million, or alternatively, of at least $0.8 million. On April 1, 2011, the plaintiffs filed a motion for a preliminary injunction, seeking an order compelling the defendants to turn over all Illinois customer accounts and prohibiting TwinSpires.com from using that list of Illinois customer accounts. On April 18, 2011, the defendants filed an answer and a motion to dismiss certain counts of the plaintiffs' complaint, and Youbet.com asserted a counterclaim seeking certain declaratory relief relating to allegations that plaintiffs Maywood and Balmoral breached the Agreement in 2010, leading to its proper termination by Youbet.com on December 1, 2010. The preliminary injunction hearing took place on July 6, 2011, and on July 21, 2011, the court denied the preliminary injunction. The parties remain engaged in the discovery process, and mediation is scheduled for March 2012.

There are no other material pending legal proceedings, other than litigation arising in the ordinary course of our business.
