INDEX METHODOLOGY

The Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated investment-grade corporate bonds with effective maturities in the same calendar year. The effective maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security as determined in accordance with a rules-based methodology developed by Accretive Asset Management LLC (“Accretive” or the “Index Provider”).

INDEX CONSTRUCTION

1. Securities eligible for inclusion in the Index are U.S. dollar-denominated fixed-income securities of corporate issuers that meet the following criteria:
   • have at least $500 million of outstanding face value;
   • are rated investment grade by at least one Nationally Recognized Statistical Rating Organization (“NRSRO”);
   • are issued by companies domiciled in the U.S., Canada, Western Europe or Japan; and
   • are not Rule 144A securities, private placements or retail bonds.
2. Each Index is limited to securities that pay fixed amounts of interest and the following types of securities are specifically excluded:
   • floating-rate securities;
   • zero-coupon bonds and zero-coupon step-up bonds;
   • convertible securities; and
   • inflation- and other index-linked bonds.
3. Each Index is constructed as follows:
   • At the beginning of each calendar year and immediately preceding an Index’s target maturity year,
     • each Index undergoes an effective maturity reconstitution, where bonds in the universe of eligible securities are assigned to an Index based on their actual maturities or, in the case of callable bonds, effective maturities as determined by a proprietary, rules-based process.
     • each Index is rebalanced based on the market values of the Index’s constituents on a monthly basis. Additions to or removals from the universe of eligible securities are reflected in each monthly rebalancing.
     • proceeds of constituents that are called or mature between rebalances are reinvested in 13-week U.S. Treasury Bills until the next monthly rebalancing of the Index. The reinvested amount is reallocated on a pro rata basis across Index constituents at the next monthly rebalance.
   • During an Index’s target maturity year,
     • the Index is calculated using a proprietary methodology that seeks to track the return of a held-to-maturity individual bond. In accordance with this methodology, the portfolio of bonds established in connection with the last reconstitution and rebalancing of an Index prior to its target year of maturity will be fixed for the remainder of the life of the Index.
     • as bonds in an Index mature or are called and principal is returned, proceeds are re-invested in 13-week U.S. Treasury Bills until the termination of the Index. It is expected that each Index will consist largely, if not completely, of a portfolio of 13-week U.S. Treasury Bills when it terminates.
4. Decisions regarding additions to and removals from an Index are made by the Index Provider and are subject to periodic review by a policy steering committee known as the BulletShares® Index Committee.

RISKS AND OTHER CONSIDERATIONS

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money.

Investment Risk. An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.

Interest Rate Risk. As interest rates rise, the value of fixed-income securities held by the Fund are likely to decrease. Securities with longer durations tend to be more sensitive to interest rate changes, making them more volatile than securities with shorter durations.

Credit/Default Risk. Credit risk is the risk that issuers or guarantors of debt instruments or the counterparty to a derivatives contract, repurchase agreement or loan of portfolio securities is unable or unwilling to make timely interest and/or principal payments or otherwise honor its obligations. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. Securities issued by the U.S. government have limited credit risk. Credit rating downgrades and defaults (failure to make interest or principal payment) may potentially reduce the Fund’s income and share price.

Asset Class Risk. The bonds in the Fund’s portfolios may underperform the returns of other bonds or indexes that track other industries, markets, asset classes or sectors. Different types of bonds and indexes tend to go through different performance cycles than the general bond market.

Call Risk/Prepayment Risk. During periods of falling interest rates, an issuer of a callable bond may exercise its right to pay principal on an obligation earlier than expected. This may result in the Fund reinvesting proceeds at lower interest rates, resulting in a decline in the Fund’s income.

Extension Risk. Extension risk is the risk that an issuer will exercise its right to pay principal on an obligation later than expected. This may happen when there is a rise in interest rates. Under these circumstances, the value of the obligation will decrease and the Fund’s performance may suffer from its inability to invest in higher yielding securities.

Income Risk. Income risk is the risk that falling interest rates will cause the Fund’s income to decline.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase or sell. If the Fund invests in illiquid securities or securities that become illiquid, Fund returns may be reduced because the Fund may be unable to sell the illiquid securities at an advantageous time or price.

Foreign Issuers Risk. The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries, and potential restrictions of the flow of international capital. Foreign companies may be subject to less governmental regulation than U.S. issuers. Moreover, individual foreign economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital investment, resource self- sufficiency and balance of payment options.

Declining Yield Risk. During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Fluctuation of Yield and Liquidation Amount Risk. The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Derivatives Risk. A derivative is a financial contract, whose value depends on, or is derived from, the value of an underlying asset such as a security or index. The Fund may invest in certain types of derivatives contracts, including futures, options and swaps. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus the Fund’s losses may be greater if it invests in derivatives.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds that track indices whose composition changes less frequently.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. Since the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index as would be the case if it purchased all of the securities in the Index with the same weightings as the Index. This would also apply to the extent the Fund uses futures or other derivative positions in lieu of investing directly in certain Index components.

Replication Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than that of larger issuers.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.
