Conservative Active + Passive You want lower risks, safer choices and preservation of your investment. You hope for modest growth over the long-term, but don’t like the idea of big swings from year to year. Perhaps you’re nearing a financial goal or life milestone, so avoiding loss is important. Passive Only Keeping risk at bay is your primary concern because preservation of your investment is important. You hope for modest growth over the long-term. To help get the most out of every penny, you want the cost efficiency that comes from passively managed funds. Moderate Active + Passive You hope for moderate growth over the long-term, but don’t like big swings from year to year. You seek a blend of risk and safety. Diversification remains important, but you can withstand some loss in a given year. Passive Only Your goal is for steady growth over the long-term, but also to avoid volatility. Diversification can help power some growth without taking big risks. A passive management approach aligns with your goals to keep costs at a minimum. Aggressive Active + Passive Time may be on your side, so perhaps you’re comfortable with the idea that more investment risk can bring higher return, even though it can also mean greater losses. Diversification, even across riskier investments, is important. Passive Only You’re comfortable with higher risks in return for better investment performance. Perhaps you’re still a long time away from your goals and can tolerate some bumps in the road. You want the cost efficiency of passive funds helping to put more of your dollars to work.

Horizon | Express Portfolios Important Disclosures This brochure must be preceded or accompanied by a current prospectus and product brochure. Before investing, you should 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 cmannuities.com, or call 888.888.3940. Annuities are long-term insurance products designed for retirement purposes. Many variable 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. 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 the issuer and do not extend to the performance of the underlying accounts which can fluctuate with changes in market conditions. 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. The range of fees and charges includes contract fees of 1.50% to 1.75%, surrender charges of 0% to 9% and management fees that vary by variable subaccount investment option. Withdrawals of taxable amounts are subject to ordinary income tax, and if taken before age 59 ½ 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. The company does not provide tax or legal advice. Contact a licensed professional. 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 transfer your value from that risk control account to the variable subaccounts. You’ll have 30 days after your risk control account anniversary to make this transfer. There is no guarantee that the S&P 500 Index or MSCI EAFE Index will be available during the entire time you own your contract. We reserve the right to add, delete or substitute an index. If we substitute an index, the performance of the new index may differ from the original index. This, in turn, may affect the performance of your risk control accounts. We will not substitute an index until approved by the insurance department in your state. We reserve the right to add or substitute a risk control account. We will notify you of any change in a risk control account or Index in advance. Notification will be in your annual report unless timing of any such change would cause us to send notification prior to your risk control account anniversary.
