The Company Hannon Armstrong Sustainable Infrastructure Capital, Inc. (the Company) focuses on making investments in climate change solutions by providing capital to the leading companies in the energy efficiency, renewable energy and other sustainable infrastructure markets. Our goal is to generate attractive returns from a diversified portfolio of projects with long-term and predictable cash flows from proven technologies that reduce carbon emissions or increase resilience to climate change. The Company and its subsidiaries are hereafter referred to as we, us, or our. Our investments take various forms, including equity, joint ventures, lending or other financing transactions, as well as real estate ownership and typically benefit from contractually committed high credit quality obligors. We also generate on-going fees through gain-on-sale securitization transactions, advisory services and asset management. We refer to the income producing assets that we hold on our balance sheet as our Portfolio. Our Portfolio may include:  Equity investments in either preferred or common structures in unconsolidated entities;  Government and commercial receivables, such as loans for renewable energy and energy efficiency projects;  Real estate, such as land or other assets leased for use by sustainable infrastructure projects typically under long-term leases; and  Investments in debt securities of renewable energy or energy efficiency projects. We finance our business through cash on hand, borrowings under credit facilities and debt transactions, asset-backed securitization transactions and equity issuances. We also generate fee income through securitizations and syndications, by providing broker/dealer services and by managing and servicing assets owned by third parties. Some of our subsidiaries are special purpose entities that are formed for specific operations associated with investing in sustainable infrastructure receivables for specific long-term contracts. Our common stock is listed on the New York Stock Exchange (NYSE) under the symbol HASI. We have qualified as a real estate investment trust (REIT) and also intend to continue to operate our business in a manner that will maintain our exemption from registration as an investment company under the 1940 Act, as amended. We operate our business through, and serve as the sole general partner of, our operating partnership subsidiary, Hannon Armstrong Sustainable Infrastructure, L.P., (the Operating Partnership), which was formed to acquire and directly or indirectly own our assets.
