​ Unit Repurchase Program ​ In May 2018, the MGP board of directors approved the establishment of a unit repurchase program authorizing us to repurchase and retire up to $100 million of ARLP common units. The program has no time limit and we may repurchase units from time to time in the open market or in other privately negotiated transactions. The unit repurchase program authorization does not obligate us to repurchase any dollar amount or number of units. No unit repurchases were made during the nine months ended September 30, 2021. Since inception of the unit repurchase program, we have repurchased and retired 5,460,639 units at an average unit price of $17.12 for an aggregate purchase price of $93.5 million. The remaining authorized amount for unit repurchases under this program is $6.5 million. ​ Change in Partners' Capital ​ The following tables present the quarterly change in Partners' Capital for the nine months ended September 30, 2021 and 2020: ​
