Description of Business	Description of Business Arbor Realty Trust, Inc. (“we,” “us,” “our,” or the "Company") is a Maryland corporation formed in 2003. We are a nationwide real estate investment trust (“REIT”) and direct lender, providing loan origination and servicing for commercial real estate assets. We operate through two business segments: our Structured Loan Origination and Investment Business, or “Structured Business,” and our Agency Loan Origination and Servicing Business, or “Agency Business.” Through our Structured Business, we invest in a diversified portfolio of structured finance assets in the multifamily, single-family rental (“SFR”) and commercial real estate markets, primarily consisting of bridge loans, in addition to mezzanine loans, junior participating interests in first mortgages and preferred equity. We also invest in real estate-related joint ventures and may directly acquire real property and invest in real estate-related notes and certain mortgage-related securities. Through our Agency Business, we originate, sell and service a range of multifamily finance products through the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac,” and together with Fannie Mae, the government-sponsored enterprises, or “GSEs”), the Government National Mortgage Association (“Ginnie Mae”), Federal Housing Authority (“FHA”) and the U.S. Department of Housing and Urban Development (together with Ginnie Mae and FHA, “HUD”). We retain the servicing rights and asset management responsibilities on substantially all loans we originate and sell under the GSE and HUD programs. We are an approved Fannie Mae Delegated Underwriting and Servicing (“DUS”) lender nationally, a Freddie Mac Multifamily Conventional Loan lender, seller/servicer in New York, New Jersey and Connecticut, a Freddie Mac affordable, manufactured housing, senior housing and small balance loan (“SBL”) lender, seller/servicer nationally and a HUD MAP and LEAN senior housing/healthcare lender nationally. We also originate and retain the servicing rights on permanent financing loans underwritten using the guidelines of our existing agency loans sold to the GSEs, which we refer to as “Private Label” loans and originate and sell finance products through CMBS programs. We either sell the Private Label loans instantaneously or pool and securitize them and sell certificates in the securitizations to third party investors, while retaining the highest risk bottom tranche certificate of the securitization. Substantially all of our operations are conducted through our operating partnership, Arbor Realty Limited Partnership (“ARLP”), for which we serve as the indirect general partner, and ARLP’s subsidiaries. We are organized to qualify as a REIT for U.S. federal income tax purposes. A REIT is generally not subject to federal income tax on that portion of its taxable income that is distributed to its stockholders, provided that at least 90% of its taxable income is distributed and provided that certain other requirements are met. Certain of our assets that produce non-qualifying REIT income, primarily within the Agency Business, are operated through taxable REIT subsidiaries (“TRS”), which are part of our TRS consolidated group (the “TRS Consolidated Group”) and are subject to U.S. federal, state and local income taxes. In general, our TRS entities may hold assets that the REIT cannot hold directly and may engage in real estate or non-real estate-related business.
