There are ongoing efforts to amend or expand the federal, state and local regulation of some of the services offered over our cable systems, particularly our retail broadband Internet access service. Potential legislative and regulatory changes could adversely impact our business by increasing our costs and competition and limiting our ability to offer services in a manner that would maximize our revenue potential. These changes have in the past, and could in the future, include, for example, the reclassification of Internet services as regulated telecommunications services or other utility-style regulation of Internet services; restrictions on how we manage our Internet access services and networks; the adoption of new customer service or service quality requirements for our Internet access services; the adoption of new privacy restrictions on our collection, use and disclosure of certain customer information; new data security and cybersecurity mandates that could result in additional network and information security and cyber incident reporting requirements for our business; new restraints on our discretion over programming decisions; new restrictions on the rates we charge to consumers for one or more of the services or equipment options we offer; changes to the cable industry's compulsory copyright to retransmit broadcast signals; new requirements to assure the availability of navigation devices from third-party providers; new Universal Service Fund contribution obligations on our Internet service revenues that would add to the cost of that service; increases in government-administered broadband subsidies to rural areas that could result in subsidized overbuilding of our facilities; changes to the Federal Communications Commission's ("FCC") administration of spectrum; pending court challenges to the legality of the FCC's Universal Service programs, which, if successful, could adversely affect our receipt of universal service funds, including but not limited to FCC Rural Development Opportunity Fund ("RDOF") grants to expand our network, FCC E-rate funds to serve schools and libraries and FCC Rural Health Care funds to serve eligible health care providers; and changes in the regulatory framework for voice over Internet protocol ("VoIP") telephone service, including the scope of regulatory obligations associated with our VoIP telephone service and our ability to interconnect our VoIP telephone service with incumbent providers of traditional telecommunications service.
We participated in the ACP and continue to participate in the RDOF subsidy program. The ACP program previously provided up to a $30 monthly subsidy enabling eligible low-income households to purchase our Internet products at a discount or, for a portion of those households, at no cost. The FCC prohibited service providers from enrolling new participants into the ACP after February 7, 2024 and April 2024 was the last month ACP households received the full ACP subsidy. ACP households received a $14 federally funded ACP subsidy in May 2024. As of June 1, 2024, ACP households no longer received the ACP benefit. The end of the ACP benefit has been, and will continue to be, disruptive to our business. We have lost and will continue to lose customers and revenues and could face greater difficulty in providing services to low-income households in the future.
As a winning bidder in the FCC's RDOF auction in 2020, we must comply with numerous FCC and state requirements to continue receiving such funding. To comply with these requirements, in RDOF areas, we have chosen to offer certain of our VoIP telephone services, such as our Lifeline services, subject to certain traditional federal and state common carrier regulations. Additionally, in some areas where we are building pursuant to subsidy programs, we will offer certain of our broadband Internet access services subject to required discounts and other marketing-related terms. If we fail to comply with those requirements, the governing regulatory agency could consider us in default and we could incur substantial penalties or forfeitures. If we fail to attain certain specified infrastructure build-out requirements under the RDOF program, the FCC could also withhold future support payments until those shortcomings are corrected. Any failure to comply with the rules and requirements of a subsidy grant could result in us being suspended or disbarred from future governmental programs or contracts for a significant period of time, which could adversely affect our results of operations and financial condition.
Participation in ACP, RDOF, and other government programs, including state subsidized builds, creates the risk of claims of our failure to adequately comply with the regulatory requirements of those programs. The FCC, and various state and federal agencies and attorney generals, may subject those programs, or other industry practices, to audits and investigations, which could result in enforcement actions, litigation, fines, settlements or reputational harm, and/or operational and financial conditions being placed on us, any of which could adversely affect our results of operations and financial condition.
If any laws or regulations are enacted that would expand the regulation of our services, they could affect our operations and require significant expenditures. We cannot predict future developments in these areas, and any changes to the regulatory framework for our Internet, video, mobile or VoIP services could have a negative impact on our business and results of operations.
It remains uncertain what rule changes, if any, will ultimately be adopted by Congress, the FCC, the Federal Trade Commission and state legislatures and regulatory agencies, and what operating or financial impact any such rules might have on us, including on the operation of our broadband networks, customer privacy and the user experience.
