  Helping take the risk out of retirement.  

The retirement landscape: financial markets. For most of us, the retirement landscape looks a lot different than the one our grandparents expected. We’re faced with new risks and new realities.   Market volatility We’re part of a growing global investment marketplace that seems wildly unpredictable. Low rates Interest rates can impact so-called “safe” investments like bonds and CDs, and that may make it difficult to earn a reasonable return.

Most certificates are considered short-term investments, while annuities are considered long-term investments. The investment in a certificate is insured by the federal government, either through the FDIC or NCUA. Any guarantees provided by an annuity are backed by an insurance company. 3

Growth with risk control and access to income are key components to achieving a comfortable, confident retirement. Longevity Most of us are living longer, more active lives, but often without the pension plans of the past.

MEMBERS® Zone Annuity is an insurance contract that offers both index-linked returns and a limit on market losses. You can set your downside limit — called a floor — along with a corresponding cap on the upside. Once your floor is set, you can’t lose more than that, no matter what happens in the markets. These upside and downside limits are connected. Your account allocation When you purchase Zone, you decide how much of your payment to allocate to the annuity’s two risk control accounts. Each is linked to a market index for an initial index period, and each has its own range of possible investment performance. >> The Secure Account has a declared rate cap and a 0% floor. These dollars are safe from market downturns and receive modest growth potential. >> The Growth Account has a higher declared cap and a -10% floor. These dollars can experience limited losses if the market is down, but when it’s up they have more room to grow. Risk Control ZONE By blending your allocation to the two accounts, you set your personal comfort zone to control market risk and participate in market reward. And you can reallocate between accounts each year, to adjust your zone as needs change.

Risk control protects the growth potential of your investments. Investment strategies that include risk control can protect you from drastic market dips and provide confidence as you work toward your retirement goals. Index-linked risk control accounts let you set a “comfort zone” based on how much you’re potentially willing to lose. That guaranteed limit on loss can keep you invested in the markets during good times and bad, freeing you from trying to “time” your investment strategy and offering potentially stabler long-term returns. >> If the index goes up, you’re credited the percentage increase, up to each risk control account’s rate cap. >> If the index goes down, value in the Growth Account is reduced by the percentage decrease, but only down to the maximum rate floor of -10%. Value in the Secure Account — because it has a 0% floor — remains the same. Rate cap: 15% If the S&P 500 goes up 18%, and your rate cap is 15%, you will be credited 15%.   0% Rate floor: -10% If the S&P 500 goes down 30%, and your rate floor is -10%, you will only lose 10%. Hypothetical examples are for illustrative purposes only and do not guarantee or predict actual performance. The example above assumes 100% allocation to the Growth Account.   You may not invest directly in an index.

Lock in the gain, lock out the loss. These charts show how your choice of zone and the performance of the index determine interest credited to your contract for a given year. In these two scenarios, rate caps are 5% for the Secure Account and 13% for the Growth Account. A 50/50 allocation means a blended comfort zone with 9% upside potential and -5% downside protection. In scenario A, the index is up 8% for the year. In scenario B, it’s down 8%. Hypothetical values show how it all comes together to help you lock in gains when times are good, and lock out losses outside your comfort zone when times are bad.   A Market gain S&P 500 Index returns 8% Zone purchase payment of $100,000 grows to $106,500 +8% 50% / $50,000 Allocated to Secure Account + 50% / $50,000 Allocated to Growth Account = Index Interest Your Blended Zone Calculation Cap 5% Your Return 5% Cap 13% Your Return 8% Cap 9% Your Return 6.5%   0% Floor -10% Floor -5% Floor   B Market loss S&P 500 Index returns -8% Zone purchase payment of $100,000 is protected at $96,000 50% / $50,000 Allocated to Secure Account Cap 5% + 50% / $50,000 Allocated to Growth Account Cap 13% = Index Interest Your Blended Zone Calculation   Cap 9%   0% Floor 0% Your Return -10% Floor -8% Your Return -5% Floor -4% Your Return   -8% You may not invest directly in an index. Hypothetical examples do not represent any specific annuity and may not be used to project or predict investment results. Rate caps are declared based on current market conditions and are subject to change. Rate caps vary by index period and can be adjusted annually on contract anniversary, subject to a minimum of 1% and a bailout provision. If the rate cap is set below an account’s bailout rate, you may withdraw value from that account without surrender charge or market value adjustment during the 30 days following anniversary. 7  

Zone in action. Armed with the downside limit, Zone’s compound annual growth rate (CAGR) could be higher than a traditional portfolio of stocks and bonds that have no protection. This chart shows how hypothetical portfolios with a comfort zone are able to quickly recover from a dramatic drop and enjoy the gains that follow.

More value, all in one place.   Reallocation and rebalancing Each year you can reset your zone by reallocating between accounts. If you don’t reallocate, accounts automatically rebalance on anniversary to maintain your zone. Future flexibility At the end of your initial index period, value is automatically allocated to the Secure Account and the Growth Account is no longer available. Based on your needs, you can make new choices at that time. See your fact sheet for the options available to you.   Health hardships You have total access to contract value in times of critical need, including confinement to a nursing home or hospital, or diagnosis of a terminal illness.1 Guaranteed income for life After two years you have options to convert your contract value into a stream of retirement income.1 Legacy for loved ones In the event of death before starting annuity income, your entire contract value passes to your named beneficiaries. A long-term promise Purchasing an annuity represents an important step — your commitment to retirement planning and our promise to protect your investment for the future. As a result, annuities are designed to be held until the end of the index period. If needs arise, after one year you can annually withdraw up to 10% of last anniversary value without penalty.2 Withdrawals in excess of 10% are assessed a surrender charge and market value adjustment during the initial index period. Refer to the fact sheet for your selected index period for these charges. After the index period, you have total access to your contract value.     There are no contract fees, administrative fees or upfront charges for Zone. When you invest, your purchase payment goes immediately to work — with a company you can trust. 1 Availability and benefits vary by state. 2 Withdrawals before age 59½ may be subject to a 10% federal tax penalty. Consult your financial advisor and tax professional regarding the impact of any withdrawals. 9

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. This brochure must also be accompanied by a prospectus and fact sheet for the selected initial index period. To obtain a prospectus and fact sheet, contact your advisor, log on to cmannuities.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. 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. Past performance is no guarantee of future results. All hypothetical examples are for illustrative purposes only and do not guarantee or predict actual performance. 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. 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 risk control account 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 after your risk control account 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. MEMBERS Life does not provide tax or legal advice. Contact a licensed professional. There are distinct differences between annuities and Certificates or CDs. Most CDs are considered a short-term investment. An annuity is considered a long-term investment. The investment in a CD is insured by the federal government, either through FDIC or NCUA. The investment in an annuity is guaranteed by an insurance company. Like CDs, fixed annuities have a penalty for early surrender, and withdrawals taken before the age of 59 from an annuity may be subject to a 10% federal tax penalty.
