sensitivity, market
perception of the creditworthiness of the issuer and general market liquidity. When interest rates rise, the value of corporate debt can be expected to decline. Debt securities with longer maturities
tend to be more sensitive to interest rate movements than those with shorter
maturities.
Quality-Value Score Risk is the risk that the Fund’s investment in companies whose securities are believed to be undervalued will not appreciate in value as
anticipated or the past performance of companies that have exhibited quality
characteristics does not continue. Although the Underlying Index is designed to measure the performance of a portfolio of bonds with certain characteristics, there is no assurance that the Underlying
Index or Fund will be comprised of such securities or that the Underlying Index's
optimization process will achieve the intended results.
Concentration Risk is the risk that, if the Fund is concentrated in a particular industry or group of industries, the
Fund is likely to present more risks than a fund that is broadly diversified over
several industries or groups of industries. Compared to the broad market, an individual
industry may be more strongly affected by changes in the economic climate, broad market
shifts, moves in a particular dominant stock or regulatory changes.
•Financial Sector Risk is the risk that the financial sector can be significantly affected by changes in interest rates, government regulation, the rate of
corporate and consumer debt defaulted, price competition, and the availability and cost
of capital, among other factors.
Income Risk is the risk that the Fund’s income may decline when interest rates fall. This decline can
occur because the Fund must invest in lower-yielding bonds as bonds in its portfolio
mature, bonds in the Underlying Index are substituted or the Fund otherwise needs to purchase additional bonds.
Market Risk is the risk that the value of the Fund’s investments may increase or decrease in response to expected, real or perceived economic, political or
financial events in the U.S. or global markets. The frequency and magnitude of such
changes in value cannot be predicted. Certain securities and other investments held by the Fund may experience increased volatility, illiquidity, or other potentially adverse effects in response to changing
market conditions, inflation, elevated levels of government debt, changes in interest
rates, lack of liquidity in the bond or equity markets, or volatility in the equity markets. Market disruptions caused by local or regional events such as financial institution failures, changes in trade
regulation or economic sanctions, internal unrest and discord, war, acts of terrorism,
the spread of
infectious illness (including epidemics and pandemics) or other public health issues, recessions or other events or adverse investor sentiment could have a significant impact on the Fund and its
investments. Such events could result in the Fund’s shares trading at increased
premiums or discounts to the Fund’s NAV. During periods of market disruption or
other abnormal market conditions, the Fund’s exposure to the risks described elsewhere in this summary will likely increase.
Index Risk is the risk that the Fund would not necessarily buy or sell a security unless that security is
added to or removed from, respectively, the Underlying Index, even if that security
generally is underperforming, because unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Additionally, the Fund
rebalances and/or reconstitutes its portfolio in accordance with the Underlying Index,
and, therefore, any changes to the Underlying Index’s rebalance and/or reconstitution schedule will result in corresponding changes to the Fund’s rebalance and/or reconstitution schedule.
Tracking Error Risk is the risk that the Fund’s performance may vary from the performance of the Underlying Index
as a result of creation and redemption activity, transaction costs, expenses and other
factors. Market disruptions, regulatory restrictions or other abnormal market conditions
could have an adverse effect on the Fund's ability to adjust its exposure to required
levels in order to track its Index or cause delays in the Underlying Index's rebalancing schedule. During any such delay, it is possible that the Underlying Index, and, in turn, the Fund will
deviate from the Underlying Index's stated methodology and therefore experience returns
different than those that would have been achieved under a normal rebalancing or reconstitution schedule.
Sampling Risk is the risk that the Fund’s use of a representative sampling approach may not work as intended
and result in increased tracking error because the securities selected for the Fund in
the aggregate may vary from the investment profile of the Underlying Index. Additionally,
the use of a representative sampling approach may result in the Fund holding a smaller
number of securities than the Underlying Index, and, as a result, an adverse development
to an issuer of securities that the Fund holds could result in a greater decline in NAV
than would be the case if the Fund held all of the securities in the Underlying Index.
Authorized Participant Concentration Risk is the risk that the Fund may be adversely affected because it has a limited number of institutions that act as authorized participants
