The contract summary must be a separate document. All information required to be disclosed must be set out in such a manner as not to minimize or render any portion thereof obscure. Any amounts which remain level for two or more contract years may be represented by a single number if it is clearly indicated what amounts are applicable for each contract year. Amounts in WAC 284-23-330 (4), (6), (7) and (9) shall, in the case of flexible premium annuity contracts, be determined either according to an anticipated pattern of consideration payments or on the assumption that considerations payable will be $1,000 per year. If not specified in the contract, annuity payments shall be assumed to commence at age 65 or 10 years from issue, whichever is later. Zero amounts shall be displayed as zero and shall not be displayed as blank spaces.
