Whenever the laws of any other state, or the rules and regulations of the insurance department of any such state, shall require of insurance companies organized under the laws of this state the payment of loan, surrender or nonforfeiture values to policyholders of such companies with such other state or states, based upon a minimum rate of interest less than that used by such Nebraska company, or companies, in computing the amount of such loan, surrender or nonforfeiture values to be paid to its policyholders within this state, then, as a condition precedent to a company organized under the laws of such other state being permitted to conduct or continue to conduct business in this state, the Department of Insurance may require that such company shall compute the loan, surrender or nonforfeiture values to be paid to Nebraska policyholders by such company or companies of such other state on the basis of a minimum interest rate less than the interest rate used by such company or companies as a basis for such loan, surrender or nonforfeiture values in its home state, by an amount equal to the difference between the rate used by such Nebraska company or companies in computing such values to be paid to its policyholders in this state and the minimum rate required by such other state or states, to be used by such Nebraska company or companies in computing the amount of such values to be paid by it to its policyholders in such other state or states.
