The most significant and subjective estimate that we make is the projection of cash flows we expect to receive on our investments, which has a significant impact on the amount of income that we record and/or disclose. In addition, the fair value of financial assets and liabilities that are estimated using a discounted cash flows method is significantly impacted by the rates at which we estimate market participants would discount the expected cash flows.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt;">In December 2019, a novel strain of coronavirus (“COVID-19”) was reported to have surfaced in Wuhan, China. COVID-19 has since spread to over 200 countries and territories, including every state in the U.S and in cities and regions where our corporate headquarters and/or properties that secure our investments, or properties that we own, are located, and is continuing to spread. On March <span style="white-space:pre-wrap;">11, 2020, the World Health Organization declared COVID-19 a pandemic, and since then, numerous countries, including the U.S., have declared national emergencies with respect to COVID-19 and have instituted “stay-at-home” guidelines or orders to help prevent its spread. Such actions are creating disruption in global supply chains, increasing rates of unemployment and adversely impacting many industries. The outbreak could have a continued adverse impact on economic and market conditions and trigger a period of global economic slowdown. The rapid development and fluidity of this situation precludes any prediction as to the ultimate adverse impact of COVID-19 on economic and market conditions. We believe the estimates and assumptions underlying </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="white-space:pre-wrap;">our consolidated financial statements are reasonable and supportable based on the information available as of September 30, 2020. However, uncertainty over the ultimate impact COVID-19 will have on the global economy generally, and our business in particular, makes any estimates and assumptions as of September 30, 2020 inherently less certain than they would be absent the current and potential impacts of COVID-19. Actual results may ultimately differ from those estimates.</span></p>
