At December 31, 2012, we obtained independent appraisals for our non-operating properties and determined that no adjustments to the carrying values were necessary. No developments have occurred subsequent to these appraisals that would indicate that impairment recognition is necessary. Although we continue to market these properties for sale, we do not anticipate that we will be able to sell the majority of the assets within the next twelve months, except as further disclosed. As such, these properties are not classified as held-for-sale as of June 30, 2013. We are currently in preliminary negotiations to sell parcels of land with carrying values totaling $2.3 million. As the terms have not been finalized, consummation of a sale of this property is not yet probable. Accordingly, we have not classified this land as held-for-sale. These properties are included in non-operating real properties in our consolidated balance sheets as of June 30, 2013 and December 31, 2012. </div>falsefalsefalsenonnum:textBlockItemTypenaDisclosure for non-operating real property consisting principally of land and undeveloped properties of the entity.No definition available.false0NON-OPERATING REAL PROPERTYfalseNON-OPERATING REAL PROPERTYUnKnownUnKnownUnKnownUnKnowntruefalsefalseSheethttp://www.mtrgaming.com/role/DisclosureNonOperatingRealProperty12
