Changes in tax laws may decrease sales and profitability of products and adversely affect our financial condition
Under current federal and state income tax law, certain products we offer, primarily life insurance and annuities, receive favorable tax treatment. This favorable treatment may give certain of our products a competitive advantage over noninsurance products. Congress from time to time considers legislation that would reduce or eliminate the favorable policyholder tax treatment currently applicable to life insurance and annuities. Congress also considers proposals to reduce the taxation of certain products or investments that may compete with life insurance and annuities. Legislation that increases the taxation on insurance products or reduces the taxation on competing products could lessen the advantage or create a disadvantage for certain of our products making them less competitive. Such proposals, if adopted, could have a material adverse effect on our profitability and financial condition or ability to sell such products and could result in the surrender of some existing contracts and policies. In addition, changes in the federal estate tax laws could negatively affect the demand for the types of life insurance used in estate planning.
