Significant Customers The following table shows customers with revenues of 10% or greater of total revenues from external customers: * Less than 10% If and when SPL, CCL or our integrated marketing function need to replace any existing SPA or enter into new SPAs, they will compete on the basis of price per contracted volume of LNG with each other and other natural gas liquefaction projects throughout the world. Revenues associated with any incremental volumes, including those sold by our integrated marketing function discussed above, will also be subject to market-based price competition. Many of the companies with which we compete are major energy corporations with longer operating histories, more development experience, greater name recognition, greater financial, technical and marketing resources and greater access to markets than us. We have proximity to our customers, with offices located in Houston, London, Singapore, Beijing and Tokyo. SPLNG currently does not experience competition for its terminal capacity because the entire approximately 4 Bcf/d of regasification capacity that is available at the Sabine Pass LNG terminal has been fully contracted. If and when SPLNG has to replace any TUAs, it will compete with other then-existing LNG terminals for customers. Our LNG terminals and pipelines are subject to extensive regulation under federal, state and local statutes, rules, regulations and laws. These laws require that we engage in consultations with appropriate federal and state agencies and that we obtain and maintain applicable permits and other authorizations. These regulatory requirements increase the cost of construction and operation, and failure to comply with such laws could result in substantial penalties and/or loss of necessary authorizations. The design, construction, operation, maintenance and expansion of our liquefaction facilities, the import or export of LNG and the purchase and transportation of natural gas in interstate commerce through our pipelines (including our Creole Trail Pipeline and Corpus Christi Pipeline) are highly regulated activities subject to the jurisdiction of the FERC pursuant to the NGA. Under the NGA, the FERC’s jurisdiction generally extends to the transportation of natural gas in interstate commerce, to the sale for resale of natural gas in interstate commerce, to natural gas companies engaged in such transportation or sale and to the construction, operation, maintenance and expansion of LNG terminals and interstate natural gas pipelines.  The FERC’s authority to regulate interstate natural gas pipelines and the services that they provide generally includes regulation of: 11 • rates and charges, and terms and conditions for natural gas transportation, storage and related services; • the certification and construction of new facilities and modification of existing facilities; • the extension and abandonment of services and facilities; • the administration of accounting and financial reporting regulations, including the maintenance of accounts and records; • the acquisition and disposition of facilities; Federal Energy Regulatory Commission Governmental Regulation Competition Percentage of Total Revenues from External Customers Year Ended December 31, 2019 2018 2017 BG and its affiliates 16% 18% 24% Naturgy 10% 14% 14% KOGAS 11% 19% 14% GAIL 11% 13% * JERA Co., Inc. * * 17%
