We write insurance policies that cover homeowners, condominium owners and commercial residential buildings for losses that result from, among other things, catastrophes. We are therefore subject to losses, including claims under policies we have assumed or written, arising out of catastrophes that may have a significant effect on our business, results of operations and financial condition. A significant catastrophe, or a series of catastrophes, could also have an adverse effect on our reinsurers. Catastrophes can be caused by various events, including hurricanes, severe convective storms, tropical storms, snowstorms, tornadoes, earthquakes, hailstorms, explosions, power outages, fires and by man-made events, such as terrorist attacks. Climate change, to the extent it produces extreme changes in temperatures and changes in weather patterns, could affect the frequency or severity of weather-related catastrophes. The incidence and severity of catastrophes are inherently unpredictable. The extent of losses from a catastrophe is a function of both the total amount of insured exposure in the area affected and the severity of the event.
As of December 31, 2023, nearly all of our premium in force related to business in coastal states, which are especially subject to adverse weather conditions such as hurricanes, tropical storms, earthquakes, and winter storms. A single catastrophic event, or a series of such events, destructive weather patterns, general economic trend, regulatory development or other condition specifically affecting the states in which we conduct business, particularly the more densely populated areas of those states, could have a disproportionately adverse impact on our business, financial condition and results of operations. Therefore, although we attempt to manage our exposure to catastrophes through our underwriting process and the purchase of reinsurance protection, an especially severe catastrophe or series of catastrophes could exceed our reinsurance protection and may have a material adverse impact on our results of operations and financial condition. As further described in Note 13 Reserve for Losses, the Company's 2017 reinsurance agreement with the FHCF was commuted during the third quarter of 2023. This commutation process resulted in a final determination of and payment for known, unknown or unreported claims relating to Hurricane Irma. The final amount paid by the FHCF could vary from the
Company's future estimation of losses to have been recovered from the FHCF. Accordingly, should future re-estimations to Hurricane Irma losses increase the expected loss reserves, all of the increase would be retained.
In total, for the period from June 1, 2022 through May 31, 2023, we have purchased an aggregate limit of $2.9 billion of catastrophe reinsurance coverage for Heritage P&C, Zephyr, and NBIC, for multiple catastrophic events. Our ability to access this coverage, however, is subject to the severity and frequency of such events. We may experience significant losses and loss adjustment expenses in excess of our retention or experience multiple retentions for a series of catastrophic events in a single season, which could materially and adversely affect our financial results.
