As of June 25, 2021, the Company also changed its principal place of business and corporate headquarters from Los Angeles to New York City, now located at 590 Madison Avenue, 33rd Floor, New York, NY 10022.

CRE debt investments primarily consist of first mortgage loans, which the Company expects to be its primary investment strategy. Additionally, the Company may selectively originate mezzanine loans and make preferred equity investments, which may include profit participations. The mezzanine loans and preferred investments equity may be in conjunction with the Company’s origination of corresponding first mortgages on the same properties. Net leased properties consist of CRE properties with long-term leases to tenants on a net-lease basis, where such tenants generally will be responsible for property operating expenses such as insurance, utilities, maintenance capital expenditures and real estate taxes. The Company will continue to target net leased equity investments on a selective basis. The Company also currently has investments in CRE debt securities primarily consisting of commercial mortgage-backed securities (“CMBS”) (“B-pieces” of a CMBS securitization pool) or CRE collateralized loan obligations (“CLOs”) (including the junior tranches thereof, collateralized by pools of CRE debt investments).</span></div><div style="margin-bottom:8pt;margin-top:8pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company was organized in the state of Maryland on August 23, 2017 and maintains key offices in New York, New York and Los Angeles, California. The Company elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, beginning with the taxable year ended December 31, 2018. The Company conducts all activities and holds substantially all assets and liabilities through the Company’s operating subsidiary, BrightSpire Capital Operating Company, LLC, (formerly known as Credit RE Operating Company, LLC, the “OP”). At December 31, 2021, the Company owned 97.7% of the OP, as its sole managing member.

(“DigitalBridge”), in accordance with that termination agreement dated April 4, 2021 between the Company, the OP, the Manager and Colony Capital Investment Advisors, LLC (the “Termination Agreement,” and the transactions contemplated thereunder, the “Internalization”). Pursuant to the Termination Agreement, the Company paid the Manager a one-time termination fee of $102.3 million. The Company will no longer pay management or incentive fees to the Manager for any post-closing period and the Company has assumed general and administrative expenses directly. The Company achieved a savings in operating costs as a result of the Internalization. Further, in connection with the Internalization, certain affiliates of the Company and the Manager entered into a transition services agreement (“TSA”) to facilitate an orderly internalization transition of the management of the Company’s operations. The TSA expired on September 30, 2021, at which time the Company fully transitioned the management of its operations. </span></div><div style="margin-bottom:8pt;margin-top:8pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company’s executive team remains unchanged, including Michael J.

Throughout 2020, continuing into the fourth quarter of 2021, countries around the world continued to face healthcare and economic challenges arising from the coronavirus, or COVID-19. Efforts to address the pandemic, such as social distancing, closures or reduced capacity of retail and service outlets, hotels, factories and public venues, often mandated by governments, have had a significant impact on the global economy and financial markets across major industries, including many sectors of real estate. In particular, the Company’s loans and preferred equity held for investment and real estate investments in the hospitality and retail sectors have experienced or anticipate a myriad of challenges, including, but not limited to: significant declines in operating cash flows of the Company’s investments which in turn affect their ability to meet debt service and covenant requirements on investment-level debt (non-recourse to the Company); flexible lease payment terms sought by tenants; increased property operating costs such as labor and supplies as a result of COVID-19; potential payment defaults on the Company's loans and preferred equity held for investment; and a distressed market affecting real estate values in general. The COVID-19 crisis may also lead to heightened risk of litigation at the investment and corporate level, with an ensuing increase in litigation and related costs.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The volatility in equity and debt markets, and the economic fallout from COVID-19 may affect the valuation of the Company’s financial assets, carried at fair value. The Company’s consideration and assessment of impairment is discussed further in Note 3, “Loans and Preferred Equity Held for Investment, net,” Note 5, “Real Estate Securities, Available for Sale,” Note 6, “Real Estate, net and Real Estate Held for Sale” and Note 14, “Fair Value.”</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">A prolonged economic downturn as a result of efforts to contain COVID-19 may continue to negatively affect the Company’s financial condition and results of operations. While the extent and duration of the broad effects of COVID-19 on the global economy and the Company remain unclear, the Company believes it has materially addressed overall recoverability in value across its assets based upon external factors known to date and assumptions using the Company’s best estimate at this time. The Company will continue to monitor the progress of the COVID-19 crisis and reassess its effects on the Company’s results of operations and recoverability in value across its assets as conditions change.</span></div>
