Revenue	Insurance premiums are recognized as revenue over the period insurance protection is provided. For additional information about our policies regarding the recognition of premium revenues, see Note 1 of the Notes to Consolidated Financial Statements included in our 2019 Annual Report on Form 10-K as filed with the Securities and Exchange Commission. Fee income includes fees and commissions for various sales, marketing and administrative services provided by our marketing and administrative companies. Revenue is recognized as these services are performed for most products. For these administrative service and other contracts, we have no material contract assets or contract liabilities on our consolidated balance sheet at September 30, 2020. Revenue recognized from performance obligations related to prior periods, and revenue expected to be recognized in future periods related to unfulfilled contractual performance obligations and contracts with variable consideration, is not material. Life Time value: The Company uses expected constrained life time values (“LTV”) representing the expected commissions to be received over the lifetime of certain policies sold, primarily Medicare Advantage products, on behalf of unaffiliated insurance carriers by IHC’s marketing agencies. Expected future commission revenue over the lifetime of the policies sold is recorded in the period the performance obligation is satisfied. No significant additional performance obligation occurs with renewal of the initial policy. IHC records substantially all anticipated revenue on these policies on the date a completed insurance application is submitted to the unaffiliated insurance carrier; adjusted for certain constraints including policyholder acceptance rates, cancellations and non-renewals. Increased sales of the aforementioned products to unaffiliated insurance carriers began in 2020 as a result of new contracts with those carriers and increased distribution channels.
