All performance information presented is hypothetical and back-tested. Hypothetical performance does not take into account estimated advisory fees and transaction costs that would apply to any account implementing the index. Actual index performance from live investment portfolios may differ materially from hypothetical returns. There is no substitute for actual returns from a live portfolio. Back-testing is done by retroactively applying a hypothesis to the historical data to obtain returns (scientific method) or finding variables in historical data that correlate to returns and developing a hypothesis from the historical data (data mining) or applying any hypothesis to different time periods until favorable returns are discovered (data mining). Back-tested models are developed with the benefit of hindsight but might not have foresight of the future. Hypothetical performance does not reflect the macroeconomic risks of investing based on the Strategy in a different time period or the financial risk of executing trades in a live portfolio which include the potential market impact on stock prices caused by buying or selling that could cause buy or sell prices to differ from the frictionless trades of the back-tested model. Although the information in the Presentation gives you some idea of the historic risks involved in investing based on the Strategy, PAST HYPOTHETICAL PERFORMANCE IS NOT A GUARANTEE OF FUTURE RETURNS.
