Introduction

The Cboe S&P 500 Dividend Aristocrats Target Income Index Monthly Series (the "SPATI Index") is part of the family of Target Outcome Indexes. The Index is a benchmark index designed to track the performance of a hypothetical buy-write strategy on constituents of the S&P 500 Dividend Aristocrats Index¹. The S&P 500 Dividend Aristocrats Index, constructed and maintained by S&P Dow Jones Indices LLC, targets companies that are currently members of the S&P 500^® Index, have increased dividend payments each year for at least 25 years, and meet certain market capitalization and liquidity requirements. The SPATI Index was launched on March 2, 2018. The SPATI Index is designed with the primary goal of generating an annualized level of income that is approximately 8% over the annual dividend yield of the S&P 500 Index and a secondary goal of generating limited capital appreciation based on the returns of the equity components of the Index. The SPATI Index investment strategy includes (1) buying the stocks contained in the S&P 500 Dividend Aristocrats Index, and (2) partially “writing” (or selling) monthly “covered” call options on each stock, generally on the third Friday of each month. The number of call options overwritten per unit of stock exposure is varied periodically with the goal of generating a total yield from dividends and call option premiums that is 8% per annum higher than the yield from dividends of the S&P 500 Index. The percentage of each stock that is overwritten with call options will by design be capped at 100%.

Target Outcome Returns

The Index is part of the family of Target Outcome Indexes. Many investments target speculative returns, with uncertain levels of risk, over an uncertain period of time. While opportunistic, this approach to investing brings a high degree of uncertainty. Target Outcome Indexes encourage targeting a specific defined return or "payoff", with an allowance for a specific defined risk, at a specific point in time in the future.

Variable Overwrite Methodology

The SPATI Index follows a variable overwrite methodology. The methodology varies the percentage of the stock portfolio that is overwritten each week with the goal of converting the potential outperformance of the stock portfolio over a benchmark and converting that outperformance into premium income through use of options. This is typically achieved by targeting a premium income level and varying the overwrite periodically to meet that income level. 1.

Index History

• SPATI Historical Values
• Daily Input Data

The Index is designed to represent a hypothetical options strategy. The actual performance of investment vehicles such as mutual funds or managed accounts can have significant differences from the performance of the Index. Investors attempting to replicate the Index should discuss with their advisors possible timing and liquidity issues. Like many passive benchmarks, the Index does not take into account significant factors such as transaction costs and taxes. Transaction costs and taxes for strategies such as the Index could be significantly higher than transaction costs for a passive strategy of buying-and-holding stocks. Investors should consult their tax advisor as to how taxes affect the outcome of contemplated options transactions. Past performance does not guarantee future results. All information for the Index prior to its launch date is backtested to calculate how the Index might have performed based on the methodology that was in effect on the launch date. Backtested performance information is purely hypothetical and is provided solely for informational purposes. Back-tested performance does not represent actual performance and should not be interpreted as an indication of actual performance. It is not possible to invest directly in an index. Cboe calculates and disseminates the Index. Supporting documentation for any claims, comparisons, statistics or other technical data is available from Cboe upon request.
