Zone | Current Rate Caps Important Disclosures Annuities are long-term insurance products designed for retirement purposes. Many registered annuities offer four main features: (1) a selection of investment options, (2) tax-deferred earnings accumulation, (3) guaranteed lifetime payout options, and (4) death benefit options. Before investing, consider the annuity’s investment objectives, risks, charges and expenses. The prospectus contains this and other information. Please read it carefully. To obtain a prospectus, contact your advisor, log on to membersproducts.com, or call 888.888.3940. This material is informational only and is not investment advice. If you need advice regarding your financial goals and investment needs, contact a financial advisor. Annuity contract values, death benefits and other values fluctuate based on the performance of the investment options and may be worth more or less than your total purchase payment when surrendered. All guarantees are backed by the claims-paying ability of MEMBERS Life Insurance Company (MEMBERS Life) and do not extend to the performance of the underlying accounts which can fluctuate with changes in market conditions. Withdrawals may be subject to surrender charges, and may also be subject to a market value adjustment (MVA). The MVA can have a positive or negative impact on contract values, depending on how interest rates have changed since the contract was issued. Surrender charges range from 0% to 9% during the initial index period. Hypothetical examples do not represent any specific annuity contract and may not be used to project or predict investment results. You may not invest directly in an index. Rate caps vary by index and by risk control account and can be adjusted annually on contract anniversary, subject to a minimum rate cap of 1% and a bailout provision. A bailout rate is set for each risk control account. If the rate cap for a given year is declared below that rate, you may withdraw value from that risk control account without surrender charge or MVA. You’ll have 30 days following contract anniversary to make this withdrawal. Withdrawals of taxable amounts are subject to ordinary income tax, and if taken before age 59½ may be subject to a 10% federal tax penalty. If you are considering purchasing an annuity as an IRA or other tax-qualified plan, you should consider benefits other than tax deferral since those plans already provide tax-deferred status.
