4. | INVENTORIES
​ Inventories consist of the following: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | December 31, | ​
​ | ​ | 2023 |  | 2022 |
​ | ​ | (in thousands) | ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Coal | ​ | $ | 56,549 | ​ | $ | 23,553 | ​
Supplies (net of reserve for obsolescence of $8,167 and $6,601, respectively) | ​ |  | 71,007 | ​ |  | 53,773 | ​
Total inventories, net | ​ | $ | 127,556 | ​ | $ | 77,326 | ​
​ The table above includes lower of cost or net realizable value adjustments of $33.3 million. These adjustments are a result of lower coal sale prices and higher cost per ton primarily due to the impact of Mettiki's longwall being idle most of the second half of 2023 due to delayed development of a new longwall district, Hamilton experiencing disruptions in production due to a longwall move, and continuing development of the Henderson County mine at our River View complex.
