[1] In May 2019, the Company sold its interest in Golden Hospitality Limited (“GHL”) to the unaffiliated shareholders of GHL resulting in a $0.4 million decrease to non-controlling interests on the Company’s consolidated balance sheet as of December 31, 2019. In July 2019, the Company purchased the remaining 25% non-controlling interest in Century Bets!, Inc. resulting in a less than $0.1 million decrease to non-controlling interest on the Company’s consolidated balance sheet as of December 31, 2019.

[2] In January 2019, the Company recognized the cumulative effect of the accounting change related to the adoption of Accounting Standards Update 2016-02, Leases (Topic 842). The Company used the alternative modified retrospective method, also known as the transition relief method, which did not require the restatement of prior periods and instead recognized a $0.3 million cumulative effect adjustment to retained earnings upon transition.
