Reinsurance
The Company purchases retrocession and reinsurance to limit and diversify the Company’s risk exposure and increase its own insurance and reinsurance underwriting capacity. These agreements provide for recovery of a portion of losses and loss adjustment expenses from reinsurers. As is the case with most reinsurance contracts, the Company remains liable to the extent that reinsurers do not meet their obligations under these agreements and therefore, in line with its risk management objectives, the Company evaluates the financial condition of its reinsurers and monitors concentrations of credit risk. The largest concentrations of un-collateralized reinsurance recoverables for unpaid losses as at March 31, 2017 were 17.0% (December 31, 2016  — 16.8%) with Munich Re which is rated AA- by S&P, 10.4% (December 31, 2016 — 12.8%) with Lloyd’s syndicates which are rated A+ by S&P and 5.8% (December 31, 2016  — 6.5%) with Arch Re which is rated A+ by S&P.
