In the course of our operations, we process, handle, store and transport a wide variety of food and non-food products, operate and maintain vehicle fleets, operate forklifts and other equipment, store fuel in on-site aboveground and underground storage tanks, and sell, use and dispose of hazardous substances including in connection with our use of our ammonia or freon-based refrigeration systems, propane, and battery-powered forklifts. Our operations are subject to a broad range of laws and regulations including regulations governing the processing, packaging, storage, distribution, marketing, advertising, labeling, transportation, export, quality and safety of our food and non-food products, as well as rights of our employees and the protection of the environment. Changes in legal or regulatory requirements (such as new product safety requirements, revised regulatory requirements for the sourcing, processing and packaging of products, and requirements to restrict or phase-out certain chemicals and ozone-depleting substances or otherwise regulating greenhouse gas emissions), or evolving interpretations of existing legal or regulatory requirements, may result in increased compliance cost, capital expenditures and other financial obligations including costs to upgrade, phase out, modify or replace products or equipment that could adversely affect our business, financial condition and results of operations. Our product suppliers are also subject to various laws and regulations and their alleged noncompliance with applicable laws and regulations could create potential liability or other adverse impacts for our business. We generally seek contractual representations and warranties from suppliers that they comply with all applicable laws and regulations and we maintain supplier policies requiring their ongoing compliance with applicable laws and regulations as well.
We are subject to governmental regulation regarding our relationship with our employees including minimum wage, overtime, wage payment, wage and hour, employment discrimination, harassment and immigration. Due to contracts we have with federal and state governmental entities as customers, we are subject to various disclosure obligations related to our employment practices and business operations, including the recent implementation of requirements to disclose information related to our greenhouse gas emissions, all of which are subject to audit. In addition, in response to the COVID-19 pandemic, the CDC, OSHA and various other federal, state, and local authorities have issued guidance, new interpretations of existing requirements, and implemented new requirements for employers that affect the operation of our facilities and the management of our workforce. The various federal, state and local requirements and guidance impacting our business continue to evolve, but we are continually monitoring for updates and responding to updated requirements and guidance applicable to our business as we become aware of them.
At various facilities, we are investigating and remediating known or suspected contamination from historical releases of fuel and other hazardous substances that is not currently the subject of any administrative or judicial proceeding, but we may be subject to administrative or judicial proceedings in the future for contamination related to releases of fuel or other hazardous substances.
Failing to comply with applicable legal and regulatory requirements, or encountering disagreements with respect to our contracts subject to governmental regulation, could result in a number of adverse situations. These could include investigations; litigation or other legal proceedings; administrative, civil, or criminal penalties or fines; mandatory or voluntary product recalls; cease and desist orders against operations that are not in compliance; closing facilities or operations; debarments from contracting with governmental entities; and loss or modification of existing, or denial of additional, licenses, permits, registrations, or approvals.
