​ In response to the disruptions to the economy and the uncertainty surrounding the COVID-19 pandemic, the Board of Directors of ARLP's general partner began suspending cash distributions to unitholders with the First Quarter and has continued through the quarter ended December 31, 2020. ​ 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, 2020. 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. Total units repurchased include the repurchase and retirement of 35 units representing fractional units as part of the simplification transactions completed by the ARLP Partnership on May 31, 2018 which are not part of the unit repurchase program. ​ Change in Partners' Capital ​ The following tables present the quarterly change in Partners' Capital for the nine months ended September 30, 2020 and 2019: ​
