rising at a much faster rate than wages or inflation . in particular , the rates we are charged for retransmitting local broadcast channels have been increasing substantially and may exceed our ability to increase our prices to our subscribers . going forward , our margins may face pressure if we are unable to renew our long-term programming contracts on acceptable pricing and other economic

negatively impacted as a result of programming interruptions and threatened programming interruptions in connection with the scheduled expiration of programming carriage contracts with content providers . for example , in june 2018 and november 2018 , univision communications inc. ( “ univision ” ) removed certain of its channels from our dish tv and sling tv programming lineup . on march 26 , 2019 , we and univision signed a new programming carriage contract which restored certain of these univision channels to our dish tv programming lineup . in october 2018 , at & t removed its hbo and cinemax channels from our dish tv and sling tv programming lineup , as we and at & t have been unable to negotiate the terms and conditions of a new programming carriage contract . at & t offers its programming , including its hbo and cinemax channels , directly to consumers over the internet and provides hbo for free to its subscribers under certain offers . in july 2019 , fox regional sports networks ( “ rsns ” ) also removed certain of its channels from our dish tv and sling tv programming lineup . in august 2019 , sinclair broadcast group acquired the fox rsns . we experienced a higher dish tv churn rate , higher net pay-tv subscriber losses and lower gross new dish tv subscriber activations during 2018 and 2019 , when univision , at & t and sinclair rsns removed certain of their channels from our dish tv and sling tv programming lineup . there can be no assurance that channel removals , such as the removal of the channels discussed above or others , will not have a material adverse effect on our business , results of operations and financial condition or otherwise disrupt our business . ​ 53 ​ ​ ​ we can not predict with any certainty the impact to our net pay-tv subscriber additions , gross new dish tv subscriber activations , and dish tv churn rate resulting from additional programming interruptions or threatened programming interruptions that may occur in the future . as a result , we may at times suffer from periods of lower net pay-tv subscriber additions or higher net pay-tv subscriber losses . ​ master transaction agreement ​ on may 19 , 2019 , we and our wholly-owned subsidiary bss merger sub inc. , ( “ merger sub ” ) , entered into a master transaction agreement ( the “ master transaction agreement ” ) with echostar and echostar bss corporation , a wholly-owned subsidiary of echostar ( “ newco ” ) . ​ pursuant to the master transaction agreement , among other things : ( i ) echostar carried out an internal reorganization in which certain assets and liabilities of the echostar satellite services segment , the business segment of echostar that provides broadcast satellite operations and satellite services , as well as certain related licenses , real estate properties and employees ( together , the “ bss business ” ) were transferred to newco ( the “ pre-closing restructuring ” ) ; ( ii ) echostar distributed all outstanding shares of common stock , par value $ 0.001 per share , of newco ( such stock , “ newco common stock ” ) on a pro rata basis ( the “ distribution ” ) , to the holders of record of class a common
