Pierce Butler, Helvering ' v. Illinois Life Inco…
“ The phrase 'required by law' includes only reserves that directly pertain to life insurance. Other reserves, even though required by state statutes regulatory of the business authorized to be carried on by life insurance companies, are not included. Under these policies the company's liabilities on account of the investment funds are independent of those attributable to life insurance risks. The right to participate in the investment funds is not dependent upon death of the insured. The company's liability is the total of contributions to the fund plus the interest agreed to be paid. ”
