[1] (1) We reclassified $73 million in land improvements to Buildings, riverboats and leasehold and land improvements to align with our 2018 reporting presentation.

[2] The conditions that were considered prohibited forms of continuing involvement related to our sale of the Golf Course Properties (see Note 11) are no longer considered continuing involvement under the new revenue recognition standard. As a result of adopting the new standard on a full retrospective basis, we are now reflecting this transaction as a completed sale in the period in which it occurred.
