directly associated with the successful acquisition of business, principally commissions and certain premium taxes and policy issuance costs, are deferred. Costs deferred on property and casualty insurance contracts are amortized over the period in which premiums are earned. Costs deferred on traditional life insurance products and other long-duration insurance contracts are amortized on a constant level basis over the expected life of the contracts in accordance with the assumptions used to estimate the liability for future policyholder benefits for nonparticipating traditional and limited-payment contracts. The underlying assumptions for deferred policy acquisition costs and the liability for future policyholder benefits are updated concurrently.</span></div><div style="margin-bottom:9pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company did not make any changes to future assumptions for the three months ended March 31, 2024 and 2023.</span></div>
