​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | December 31, | ​

Casino |  | $ | 2,701 |  | $ | 3,599 | ​

Less allowance for doubtful accounts | ​ |  | (111) | ​ |  | (100) | ​
​ |  | $ | 3,736 |  | $ | 5,458 | ​
​ The Company calculates an allowance for doubtful accounts by applying a percentage, estimated by management based on historical aging experience, current economic conditions and management’s expectations of future economic conditions, to the accounts receivable balance. The Company recorded bad debt expense of $159 thousand, $189 thousand and $93 thousand in 2020, 2019 and 2018, respectively. ​ The decrease in accounts receivable in 2020 year-over-year is primarily a result of the decrease in net revenue and especially the revenue from groups and convention events.
