The MSCI Frontier Markets Index is an unmanaged index of &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;common stocks of issuers in countries that have less-developed economies and financial markets than more established emerging &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;markets. Frontier markets often have more restrictions on foreign stock ownership. Securities acquired by the Fund are typically listed &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;on stock exchanges in emerging market countries, but also may include securities traded in markets outside these countries. The Fund &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;may invest in securities issued by companies with a broad range of market capitalizations, including those of smaller, less seasoned &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;companies. More than 25% of the Fund&#x2019;s total assets may be denominated in any single currency.

The Fund seeks to &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;minimize income distributions and distributions of realized short-term gains that are taxed as ordinary income, as well as distributions &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;of realized long-term gains (taxed as long-term capital gains). The Fund seeks to employ a top-down, disciplined and systematic &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;investment process that emphasizes broad exposure and diversification among emerging market countries, economic sectors and &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;issuers. This rules-based strategy utilizes targeted allocation and systematic&#160;&#x2009;rebalancing to take advantage of certain quantitative and &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;behavioral characteristics of emerging markets identified by the portfolio managers. The investment process is periodically &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;re-evaluated and may be adjusted to ensure that the process is consistent with the Fund&#x2019;s investment objective and strategies. The &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;portfolio managers select and allocate across countries based on factors such as size, liquidity, level of economic development, local &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;economic diversification, and perceived risk and potential for growth. The Fund maintains a bias to broad inclusion; that is, the Fund &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;intends to allocate its portfolio holdings to more emerging market countries rather than fewer emerging market countries. Relative to &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;capitalization-weighted country indexes, individual country allocation targets emphasize the less represented emerging market &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;countries and attempt to reduce concentration risks relative to a capitalization-weighted index. The Fund&#x2019;s country allocations are &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;rebalanced to their target weights if they exceed a certain pre-determined overweight or fall below a certain pre-determined &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;underweight. Rebalancing has the effect of reducing exposure to countries with strong relative performance and increasing exposure &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;to countries which have underperformed. The frequency of rebalancing depends on the volatility and trading costs of the individual &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;country. At the portfolio level and within each country, the Fund seeks to maintain exposure across key economic sectors. Relative to &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;capitalization-weighted country indexes, the portfolio managers target weights to these sectors to emphasize the less represented &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;sectors. The portfolio managers use a quantitative model to select individual securities as representatives of their economic sectors &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;and generally weight them by their relative capitalization within that sector.&lt;/span&gt;&lt;/div&gt;</oef:StrategyNarrativeTextBlock>

For example, a government may restrict investment in companies or industries &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;considered important to national interests, intervene in the financial markets, maintain strict currency controls, or impose repatriation &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;restrictions.

In addition, there is the potential of increased tariffs and restrictions (and threats thereof) on trade &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;between the U.S. and China, concerns of which have been heightened &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;(and realized) &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;by recent developments in relations between the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;U.S., other trading partners and China&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;, including the designation of China as a &#x201c;foreign adversary&#x201d; of the U.S., as well as &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;countersanctions or countermeasures from the Chinese government that have been triggered or are expected to be triggered.&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt; An &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;increase in tariffs or trade restrictions, or even the threat of such developments, could lead to a significant reduction in international &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;trade, which could have a negative impact on China&#x2019;s export industry, Chinese issuers, the liquidity or price of the Fund&#x2019;s direct or &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;indirect investments in China and, therefore, the Fund.
