The Company's top ten suppliers accounted for 84% of our purchases during 2022, including 60% from Carrier, and 8% from Rheem. Carrier provides a diverse variety of brands of HVAC systems including, Carrier, Bryant, Payne, Tempstar, Heil, Comfortmaker and Grandaire, along with complimentary replacement parts. Rheem provides Rheem-brand HVAC systems along with complimentary replacement parts. Given the significant concentration of our supply chain, particularly with Carrier and Rheem, any significant interruption by any of the key manufacturers or a termination of a relationship could temporarily disrupt the operations of certain of our subsidiaries. Additionally, our operations are materially dependent upon the continued market acceptance and quality of these manufacturers' products and their ability to continue to manufacture products that are competitive and that comply with laws relating to environmental and efficiency standards. Our inability to obtain products from one or more of these manufacturers or a decline in market acceptance of these manufacturers' products could have a material adverse effect on our results of operations, cash flows, and liquidity.
Many HVAC equipment and component manufacturers, including Carrier and Rheem, source component parts from China and/or assemble a significant number of products for residential and light-commercial applications from Mexico. If any restrictions, including overall trade relations, a potential increase in tariffs, are imposed related to such products sourced or assembled from Mexico and China, including as a result of amendments to existing trade agreements, and our product costs consequently increase, we would be required to raise our prices, which may result in cost inflation, the loss of customers, and harm to our business. In addition, COVID-19, which surfaced in Wuhan, China in December 2019, resulted in increased travel restrictions and extended shutdown of certain businesses in the region. The continuing impact of COVID-19 on our business will depend on future developments; however, closures in China and/or Mexico may disrupt the operations of certain of our suppliers, which could negatively impact our business.
We maintain trade name and distribution agreements with Carrier and Rheem that provide us distribution rights on an exclusive basis in specified territories. Such agreements are not subject to a stated term or expiration date.
We also maintain other distribution agreements with various other suppliers, either on an exclusive or non-exclusive basis, for various terms ranging from one to ten years. Certain of the distribution agreements contain provisions that restrict or limit the sale of competitive products in the locations that sell such branded products. Other than where such location-level restrictions apply, we may distribute other manufacturers' lines of air conditioning or heating equipment in other locations in the same territories.
