Maiden Reinsurance is now subject to the statutes and regulations of Vermont in the ordinary course of business. The re-domestication, in combination with other strategic measures described above that were completed in 2019, have continued to strengthen the Company’s capital position and solvency ratios.</span></div><div style="margin-bottom:6pt;text-align:justify;text-indent:13.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:100%">While the Vermont Department of Financial Regulation ("Vermont DFR") is now the group supervisor for the Company, the re-domestication did not apply to the Parent Company which remains a Bermuda-based holding company.

We believe the formation of GLS is highly complementary to our overall longer-term strategy. GLS, along with other recent insurance industry investments, enables us to leverage our knowledge base while not re-entering active underwriting of new risks and maintaining an efficient operating profile.

Circumstances caused by the COVID-19 pandemic are complex, uncertain and rapidly evolving.

The Company's Swedish and UK insurance operations ("IIS unit") do write limited primary insurance coverages that could be exposed to COVID-19 claims. While we assess our exposure to COVID-19 insurance and reinsurance claims on our existing insurance exposures and remaining reinsurance exposures as limited and immaterial, given the uncertainty surrounding the COVID-19 pandemic and its impact on the insurance industry, our preliminary estimates of loss and loss adjustment expenses ("loss and LAE") and estimates of reinsurance recoverable arising from the COVID-19 pandemic may materially change. Maiden Reinsurance has not received any COVID-19 claims to date but our companies within our IIS unit have received a limited number of claims related to those coverages which it deems as immaterial. Unanticipated issues relating to claims and coverage may emerge, which could adversely affect our business by increasing the scope of coverage beyond our intent and/or increasing the frequency and severity of claims.</span></div><div style="margin-bottom:6pt;text-align:justify;text-indent:13.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:100%">The Company's investment portfolio may be adversely impacted by unfavorable market conditions caused by the COVID-19 pandemic, and the Company and its reinsurance subsidiaries may need additional capital to maintain compliance with regulatory capital requirements and/or be required to post additional collateral under existing reinsurance arrangements, which could reduce our liquidity. In addition, the Company may experience continued volatility in its results of operations which could negatively impact its financial condition and create a reduction in the amount of available distribution or dividend capacity from its regulated reinsurance subsidiaries, which would also reduce liquidity.</span></div>
