Under various federal, state and local environmental laws, ordinances and regulations, current or previous owners or operators of real property may be liable for the costs of removal or remediation of hazardous or toxic substances on, under or in their properties. This applies to properties we either own or operate. These laws typically impose liability without regard to whether the owner or operator knew of, or was responsible for, the presence of such hazardous or toxic substances. We may be potentially liable for such costs as a result of our operation of parking facilities. Additionally, we hold a partial ownership interest in four parking facilities, and companies that we acquired in previous years may have owned a large number of properties that we did not acquire. We may now be liable for certain costs as a result of such previous and current ownership. In addition, from time to time we are subject to legal claims and regulatory actions involving environmental issues at certain locations or in connection with our operations. The cost of defending against claims of liability, or remediation of a contaminated property, could have a material adverse effect on our business, financial condition and results of operations.
In connection with ground transportation services and certain transportation and baggage services provided to our clients, including shuttle bus operations, baggage handling and delivery services and remote airline check-in services, the U.S. Department of Transportation, including the Transportation Security Administration (TSA) and Department of Homeland Security, and various federal and state agencies exercise broad powers over these transportation and baggage related services, including, licensing and authorizations, safety, training and insurance requirements. Our employees must also comply with the various safety and fitness regulations promulgated by the U.S. Department of Transportation and other federal agencies, including those related to minimum training hours and requirements, drug and alcohol testing and service hours. We may become subject to new and more restrictive federal and state regulations. Compliance with such regulations could hamper our ability to provide qualified drivers and increase our operating costs. There can be no assurance that our compliance with new rules and regulations, directives, anticipated rules or other forms of regulatory oversight will not have a material adverse effect on us.
We are also subject to consumer credit laws and credit card industry rules and regulations relating to the processing of credit card transactions, including the Fair and Accurate Credit Transactions Act and the Payment Card Data Security Standard. These laws and these industry standards impose substantial financial penalties for non-compliance.
In addition, we are subject to laws generally applicable to businesses, including, but not limited, to federal, state and local regulations relating to data privacy, wage and hour matters, employee classification, mandatory healthcare benefits, unlawful workplace discrimination and whistle blowing. Any actual or alleged failure to comply with any regulation applicable to our business or any whistle-blowing claim, even if without merit, could result in costly litigation, regulatory action or otherwise harm our business, financial condition and results of operations.
We collect and remit sales/parking taxes and file tax returns for and on behalf of ourselves and our clients. We are affected by laws and regulations that may impose a direct assessment on us for failure to remit sales/parking taxes and filing of tax returns for ourselves and on behalf of our clients.
We cannot predict changes in laws and regulations made by the U.S. President, the U.S. President's administration, or the current and future U.S. Congress. Any such changes may pose additional regulatory burden and costs on our business or otherwise adversely affect our results of operations.
