 of the ultimate number of claims and the average cost of a claim. With the guidance of the methods above, actuarial judgment is applied in the determination of ultimate losses. In general, the Company’s segments have varying levels of seasoning with which the Company has direct experience and as a result, differing methods are utilized to estimate loss and LAE reserves in each segment.For the Diversified Reinsurance legacy business, the Company utilizes the ELR approach at the onset of reserving an account, the BF method for business with less but maturing loss experience, and as the experience matures the LD method. For proportional or pro-rata business, the Company typically relies heavily on the actual historical contract experience to estimate reserving parameters such as loss development factors, whereas for excess of loss business there will be more usage of industry and/or Company benchmark assumptions.Maiden Reinsurance underwrote the AmTrust Reinsurance legacy business from July 1, 2007 until January 30, 2019, when Maiden Reinsurance and AII agreed to terminate the remaining business subject to the AmTrust Quota Share on a run-off basis effective as of January 1, 2019, and Maiden Reinsurance, AEL and AIU DAC agreed to terminate the European Hospital Liability Quota Share on a run-off basis effective as of January 1, 2019. A large proportion of the exposure in the underlying book of business has significant seasoning, and allows for a significant amount of credibility in using parameters derived from historical experience to calculate reserve estimates. Some segments of the book are a result of recent acquisitions or newer markets for AmTrust. These segments require a greater level of assumptions and professional judgment in deriving ultimate losses, which inherently implies a wider range of reasonable estimates. As a result, the Company has tended to rely on a weighted approach which primarily employs the LD method for aspects of the segment with ample historical data, while also considering the ELR or the BF method for exposures with more limited or volatile historical data. The FS method is also considered for segments of the AmTrust Legacy Reinsurance book of business for which claim count information is available. Additional data detailing items such as class of business, state, claim counts, frequency and severity is available, further enhancing the reserve analysis. Prior period loss development ("PPD") arises from changes to loss estimates recognized in the current year that relate to loss reserves established in previous calendar years. The favorable or unfavorable PPD reflects changes in management's best estimate of the ultimate losses under the relevant reinsurance policies after
