Consolidated premiums earned, net increased 2.9% year over year, to $2.9 billion, primarily reflecting higher Managed Care and Life Insurance premiums.
The 2014 period includes a one-time $6.3 million adjustment increasing the consolidated deferred tax liability related to investments classified as available for sale after the July 1, 2014 enactment of Puerto Rico tax legislation that increased the corporate tax rate over long-term capital gains, from 15% to 20%, for all transactions occurring after June 30, 2014.
To monitor the solvency of the operations, the BCBSA requires us, TSS, TSA, and TSB to comply with certain specified levels of Risk Based Capital (”RBC”). RBC is designed to identify weakly capitalized companies by comparing each company’s adjusted surplus to its required surplus (RBC ratio). The RBC ratio reflects the risk profile of insurance companies. At December 31, 2016, TSM and TSS estimated RBC ratio was above the minimum BCBSA RBC requirement of 200% and the 375% of RBC level required by the BCBSA to avoid monitoring. At December 31, 2016, TSA estimated RBC ratio was above the minimum BCBSA RBC requirement of 100% for smaller controlled affiliate.
Pursuant to the Puerto Rico Insurance Code, our property and casualty insurance subsidiary is a member of Sindicato de Aseguradores para la Suscripción Conjunta de Seguros de Responsabilidad Profesional Médico-Hospitalaria (SIMED). The syndicate was organized for the purpose of underwriting medical-hospital professional liability insurance. As a member, the property and casualty insurance segment shares risks with other member companies and, accordingly, is contingently liable in the event the syndicate cannot meet their obligations. During 2016, 2015 and 2014, no assessment or payment was made for this contingency. It is the opinion of management that any possible future syndicate assessments will not have a material effect on our operating results and/or cash flows, although there is no ceiling on these payment obligations.
At December 31, 2016, the actuarial reserve range determined by the actuaries was from $90 million to $105 million. Management reviews the results of the reserve estimates in order to determine any appropriate adjustments in the recording of reserves. Adjustments to reserve estimates are made after management’s consideration of numerous factors, including but not limited to the magnitude of the difference between the actuarial indication and the recorded reserves, improvement or deterioration of actuarial indications in the period, the maturity of the accident year, trends observed over the recent past and the level of volatility within a particular line of business. In general, changes are made more quickly to more mature accident years and less volatile lines of business. Varying the net expected loss ratio by +/-1% in all lines of business for the six most recent accident years would increase/decrease the claims incurred by approximately $5.6 million.
The schedules of amortization of life insurance deferred policy acquisition costs (“DPAC”) and VOBA are based upon actuarial assumptions regarding future events that are uncertain. For all products, other than universal life and deferred annuities, the most significant of these assumptions is the level of contract persistency and investment yield rates. For these products the basis for the amortization of DPAC and VOBA is established at the issue of each contract and would only change if our segment’s experience deteriorates to the point that the level of the net liability is not adequate. We do not currently expect that level of deterioration to occur. For the universal life and deferred annuity products, amortization schedules are based upon the level of historic and anticipated gross profit margins, from the date of each contract’s issued (or purchase, in the case of VOBA). These schedules are based upon several actuarial assumptions that are uncertain, are reviewed annually and are modified if necessary. The most significant of these assumptions are claims, investment yield rates and contract persistency. Based upon the most recent actuarial reviews of all of the assumptions, we do not currently anticipate material changes to the level of these amortization schedules.
