(sometimes referred to as "Maiden Holdings" or "Parent Company") is a Bermuda-based holding company. Together with its subsidiaries (collectively referred to as the "Company", "We" or "Maiden"), Maiden previously focused on serving the needs of regional and specialty insurers in the United States of America ("U.S."), Europe and select other global markets. The Company operates internationally through Maiden Global Holdings, Ltd. ("Maiden Global") providing branded auto and credit life insurance products through insurer partners to retail clients in the EU and other global markets. These products also produce reinsurance programs which are underwritten by Maiden Reinsurance Ltd. ("Maiden Reinsurance"). Maiden Reinsurance does not underwrite any direct insurance business. Certain international credit life business is written on a primary basis by Maiden Life Försäkrings AB ("Maiden LF") and general insurance business is written on a primary basis by Maiden General Försäkrings AB ("Maiden GF"). We are not presently actively underwriting reinsurance business. We are also running off the liabilities associated with AmTrust Financial Services, Inc. ("AmTrust") contracts we terminated in early 2019 as discussed below.</span></div><div style="line-height:100%;padding-bottom:8px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Strategic Review</span></div><div style="line-height:100%;padding-bottom:8px;text-align:justify;text-indent:18px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Since 2018, we have engaged in a series of strategic measures that have dramatically reduced the required regulatory capital needed to operate our business, materially strengthened our solvency ratios, re-domiciled Maiden Reinsurance to Vermont in the U.S. and ceased active reinsurance underwriting. During that time, we significantly increased our estimate of ultimate losses and loss reserves while purchasing reinsurance protection against further loss reserve volatility and as a result, have improved the ultimate economic value of the Company. We believe these measures have given the Company the ability to more flexibly allocate capital to those activities most likely to produce the greatest returns for shareholders. </span></div><div style="line-height:100%;padding-bottom:8px;text-align:justify;text-indent:18px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The measures we ultimately have taken were initiated in early 2018, when our Board of Directors initiated a review of strategic alternatives (the "Strategic Review") to evaluate ways to increase shareholder value after a period of continuing higher than targeted combined ratios and lower returns on equity than planned.</span></div><div style="line-height:100%;padding-bottom:8px;text-align:justify;text-indent:18px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In addition, as of December 31, 2018, both the Company and its subsidiary Maiden Reinsurance failed to meet their requirements to hold sufficient capital to cover their respective enhanced capital requirements (“ECR”). The Company had communicated such conditions to the Bermuda Monetary Authority ("BMA") and is following the guidelines of a reportable “event” as stipulated by Bermuda insurance law. </span></div><div style="line-height:100%;padding-bottom:8px;text-align:justify;text-indent:18px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">As part of both the Strategic Review and the remediation measures implemented to cure the breach of the ECR, a series of transactions were entered into including: (1) completed the sale of Maiden Reinsurance North America, Inc. ("Maiden US") on December 27, 2018; (2) Maiden Reinsurance's shareholders, Maiden Holdings and Maiden Holdings North America, Ltd. ("Maiden NA"), made capital injections of </span><span style="font-family:inherit;font-size:10pt;"><span>$125,000</span></span><span style="font-family:inherit;font-size:10pt;"> on December 31, 2018 and </span><span style="font-family:inherit;font-size:10pt;"><span>$70,000</span></span><span style="font-family:inherit;font-size:10pt;"> on January 18, 2019 to Maiden Reinsurance from the sale proceeds of Maiden US; (3) entered into a partial termination amendment ("Partial Termination Amendment") with AmTrust effective January 1, 2019 which amended the quota share reinsurance agreement (“AmTrust Quota Share”) between Maiden Reinsurance and AmTrust’s wholly owned subsidiary AmTrust International Insurance, Ltd. (“AII”) (as more fully described in </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">"Note 8 - Reinsurance"</span><span style="font-family:inherit;font-size:10pt;">); (4) entered into amendments which terminated the AmTrust Quota Share and the European hospital liability quota share reinsurance contract ("European Hospital Liability Quota Share") with AmTrust’s wholly owned subsidiaries AmTrust Europe Limited ("AEL") and AmTrust International Underwriters DAC ("AIU DAC") effective January 1, 2019 (these transactions are broadly referred to herein as the "Final AmTrust QS Terminations"); (5) entered into the Loss Portfolio Transfer and Adverse Development Cover Agreement ("LPT/ADC Agreement") with Enstar Group Limited ("Enstar') pursuant to the revised Master Transaction Agreement entered into on March 1, 2019; and (6) entered into a Commutation and Release Agreement with AmTrust to commute certain workers' compensation business with AII as of January 1, 2019.</span></div><div style="line-height:100%;padding-bottom:8px;text-align:justify;text-indent:18px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">As a result of the completion of these steps, both the Company and Maiden Reinsurance have sufficient capital in excess of the respective ECR requirements. Please see below for additional details regarding the LPT/ADC Agreement and the Commutation and Release Agreement.</span></div><div style="line-height:100%;padding-bottom:8px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Discontinued Operations</span><span style="font-family:inherit;font-size:10pt;"> </span></div><div style="line-height:100%;padding-bottom:8px;text-align:justify;text-indent:18px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company made the strategic decision to divest its U.S. treaty reinsurance operations through the sale of Maiden US which was completed on December 27, 2018.

The sale was consummated on August 29, 2018. The Company continues to earn premiums and remain liable for losses occurring subsequent to August 29, 2018 for any policies in force prior to and as of August 29, 2018, until those policies expire. </span></div><div style="line-height:100%;padding-bottom:8px;text-align:justify;text-indent:18px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The payment received for the sale of the Renewal Rights was </span><span style="font-family:inherit;font-size:10pt;"><span>$7,500</span></span><span style="font-family:inherit;font-size:10pt;"> subject to potential additional amounts payable in the future in accordance with the agreement, however no additional fees have been recognized to date. </span></div><div style="line-height:100%;padding-bottom:8px;text-align:justify;text-indent:18px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:100%;padding-bottom:8px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-weight:bold;">1.

The LPT/ADC Agreement meets the criteria for risk transfer and therefore has been accounted for as retroactive reinsurance. Cumulative ceded losses exceeding </span><span style="font-family:inherit;font-size:10pt;"><span>$445,000</span></span><span style="font-family:inherit;font-size:10pt;"> result in a deferred gain which will be recognized over the settlement period in proportion to cumulative losses collected over the estimated ultimate reinsurance recoverable. Consequently, cumulative adverse development subsequent to </span><span style="font-family:inherit;font-size:10pt;">December 31, 2018</span><span style="font-family:inherit;font-size:10pt;"> may result in significant losses from operations until periods when the deferred gain is recognized as a benefit to earnings.

In addition to these reportable segments, the results of operations of the former National General Holdings Corporation Quota Share ("NGHC Quota Share") segment, which was commuted in November 2019, is included in the "Other" category.
