Item 8 of Part II of the Prospectus
The section entitled “Risk Factors” in Item 8 of Part II of the Prospectus is amended to add the following:
Risk of Investing in China. Investments in securities of companies domiciled in the People’s Republic of China (“China” or the “PRC”) involve a high degree of risk and special considerations not typically associated with investing in the U.S. securities markets. Such heightened risks include, among others, an authoritarian government, popular unrest associated with demands for improved political, economic and social conditions, the impact of regional conflict on the economy and hostile relations with neighboring countries.
Military conflicts, either in response to internal social unrest or conflicts with other countries, could disrupt economic development. The Chinese economy is vulnerable to the long-running disagreements with Hong Kong related to integration and religious and nationalist disputes with Tibet and the Xinjiang region. China has a complex territorial dispute regarding the sovereignty of Taiwan that has included threats of invasion; Taiwan-based companies and individuals are significant investors in China. Military conflict between China and Taiwan may adversely affect securities of Chinese issuers. In addition, China has strained international relations with Japan, India, Russia and other neighbors due to territorial disputes, historical animosities and other defense concerns. China could be affected by military events on the Korean peninsula or internal instability within North Korea. These situations may cause uncertainty in the Chinese market and may adversely affect performance of the Chinese economy.
The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. But there can be no assurance that these reforms will continue or that they will be effective. Despite reforms and privatizations of companies in certain sectors, the Chinese government still exercises substantial influence over
many aspects of the private sector and may own or control many companies. The Chinese government continues to maintain a major role in economic policy making and investing in China involves risk of loss due to expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested.
The Chinese government may intervene in the Chinese financial markets, such as by the imposition of trading restrictions, a ban on “naked” short selling or the suspension of short selling for certain stocks. This may affect market price and liquidity, and may have an unpredictable impact on the investment activities of the Fund. Furthermore, such market interventions may have a negative impact on market sentiment which may in turn affect the performance of the securities markets and as a result the performance of the Fund.
In addition, there is less regulation and monitoring of Chinese securities markets and the activities of investors, brokers and other participants than in the United States. Accordingly, issuers of securities in China are not subject to the same degree of regulation as are U.S. issuers with respect to such matters as insider trading rules, tender offer regulation, stockholder proxy requirements and the requirements mandating timely and accurate disclosure of information. Stock markets in China are in the process of change and further development. This may lead to trading volatility, difficulty in the settlement and recording of transactions and difficulty in interpreting and applying the relevant regulation. Custodians may not be able to offer the level of service and safe-keeping in relation to the settlement and administration of securities in China that is customary in more developed markets. In particular, there is a risk that the Fund may not be recognized as the owner of securities that are held on behalf of the Fund by a sub-custodian.
The Renminbi (“RMB”) is not currently a freely convertible currency and is subject to foreign exchange control policies and repatriation restrictions imposed by the Chinese government. The imposition of currency controls may negatively impact performance and liquidity in the Fund as capital may become trapped in the PRC. The Fund could be adversely affected by delays in, or a refusal to grant, any required governmental approval for repatriation of capital, as well as by the application to the Fund of any restrictions on investments. Investing in entities either in, or which have a substantial portion of their operations in, the PRC may require the Fund to adopt special procedures, seek local government approvals or take other actions, each of which may involve additional costs and delays to the Fund.
While the Chinese economy has grown rapidly in recent years, there is no assurance that this growth rate will be maintained. China may experience substantial rates of inflation or economic recessions, causing a negative effect on the economy and securities market. China’s economy is heavily dependent on export growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the securities of Chinese issuers.
The tax laws and regulations in the PRC are subject to change, including the issuance of authoritative guidance or enforcement, possibly with retroactive effect. The interpretation, applicability and enforcement of such laws by PRC tax authorities are not as consistent and transparent as those of more developed nations, and may vary over time and from region to
region. The application and enforcement of PRC tax rules could have a significant adverse effect on the Fund and its investors, particularly in relation to capital gains withholding tax imposed upon non-residents. In addition, the accounting, auditing and financial reporting standards and practices applicable to Chinese companies may be less rigorous, and may result in significant differences between financial statements prepared in accordance with PRC accounting standards and practice and those prepared in accordance with international accounting standards.
Risk of Investing through Stock Connect. China A-shares are equity securities of companies based in mainland China that trade on Chinese stock exchanges such as the Shanghai Stock Exchange (“SSE”) and the Shenzhen Stock Exchange (“SZSE”) (“A-shares”). Foreign investment in A-shares on the SSE and SZSE is historically not permitted, other than through a license granted under regulations in the PRC known as the Qualified Foreign Institutional Investor and Renminbi Qualified Foreign Institutional Investor systems. Each license permits investment in A-shares only up to a specified quota.
Investment in eligible A-shares listed and traded on the SSE is also permitted through the Shanghai-Hong Kong Stock Connect program (“Stock Connect”). Stock Connect is a securities trading and clearing program established by Hong Kong Securities Clearing Company Limited (“HKSCC”), the SSE and China Securities Depository and Clearing Corporation Limited (“CSDCC”) that aims to provide mutual stock market access between the PRC and Hong Kong by permitting investors to trade and settle shares on each market through their local exchanges. The Fund may invest in A-shares through Stock Connect or on such other stock exchanges in China which participate in Stock Connect from time to time. Under Stock Connect, the Fund’s trading of eligible A-shares listed on the SSE would be effectuated through its Hong Kong broker.
Although no individual investment quotas or licensing requirements apply to investors in Stock Connect, trading through Stock Connect’s Northbound Trading Link is subject to aggregate and daily investment quota limitations that require that buy orders for A-shares be rejected once the remaining balance of the relevant quota drops to zero or the daily quota is exceeded (although the Fund will be permitted to sell A-shares regardless of the quota balance). These limitations may restrict the Fund from investing in A-shares on a timely basis, which could affect the Fund’s ability to effectively pursue its investment strategy. Investment quotas are also subject to change.
Investment in eligible A-shares through Stock Connect is subject to trading, clearance and settlement procedures that could pose risks to the Fund. A-shares purchased through Stock Connect generally may not be sold or otherwise transferred other than through Stock Connect in accordance with applicable rules. For example, PRC regulations require that in order for an investor to sell any A-share on a certain trading day, there must be sufficient A-shares in the investor’s account before the market opens on that day. If there are insufficient A-shares in the investor’s account, the sell order will be rejected by the SSE. The Stock Exchange of Hong Kong (“SEHK”) carries out pre-trade checking on sell orders of certain stocks listed on the SSE market (“SSE Securities”) of its participants (i.e., stock brokers) to ensure that this requirement is satisfied. While shares must be designated as eligible to be traded under Stock Connect, those shares may also lose such designation, and if this occurs, such shares may be sold but cannot be
purchased through Stock Connect. In addition, Stock Connect will only operate on days when both the Chinese and Hong Kong markets are open for trading and when banks in both markets are open on the corresponding settlement days. Therefore, an investment in A-shares through Stock Connect may subject the Fund to a risk of price fluctuations on days where the Chinese market is open, but Stock Connect is not trading. Moreover, day (turnaround) trading is not permitted on the A-shares market. If an investor buys A-shares on day “T”, the investor will only be able to sell the A-shares on or after day T+1. Further, since all trades of eligible Stock Connect A-shares must be settled in RMB, investors must have timely access to a reliable supply of offshore RMB, which cannot be guaranteed.
A-shares held through the nominee structure under Stock Connect will be held through HKSCC as nominee on behalf of investors. The precise nature and rights of the Fund as the beneficial owner of the SSE Securities through HKSCC as nominee is not well defined under PRC law. There is lack of a clear definition of, and distinction between, legal ownership and beneficial ownership under PRC law and there have been few cases involving a nominee account structure in the PRC courts. The exact nature and methods of enforcement of the rights and interests of the Fund under PRC law is also uncertain. In the unlikely event that HKSCC becomes subject to winding up proceedings in Hong Kong there is a risk that the SSE Securities may not be regarded as held for the beneficial ownership of the Fund or as part of the general assets of HKSCC available for general distribution to its creditors. Notwithstanding the fact that HKSCC does not claim proprietary interests in the SSE Securities held in its omnibus stock account in the CSDCC, the CSDCC as the share registrar for SSE listed companies will still treat HKSCC as one of the shareholders when it handles corporate actions in respect of such SSE Securities. HKSCC monitors the corporate actions affecting SSE Securities and keeps participants of Central Clearing and Settlement System (“CCASS”) informed of all such corporate actions that require CCASS participants to take steps in order to participate in them. Investors may only exercise their voting rights by providing their voting instructions to the HKSCC through participants of the CCASS. All voting instructions from CCASS participants will be consolidated by HKSCC, who will then submit a combined single voting instruction to the relevant SSE-listed company.
The Fund’s investments through Stock Connect’s Northbound Trading Link are not covered by Hong Kong’s Investor Compensation Fund. Hong Kong’s Investor Compensation Fund is established to pay compensation to investors of any nationality who suffer pecuniary losses as a result of default of a licensed intermediary or authorized financial institution in relation to exchange-traded products in Hong Kong. In addition, since the Fund is carrying out Northbound trading through securities brokers in Hong Kong but not PRC brokers, it is not protected by the China Securities Investor Protection Fund in the PRC.
Market participants are able to participate in Stock Connect subject to meeting certain information technology capability, risk management and other requirements as may be specified by the relevant exchange and/or clearing house. Further, the “connectivity” in Stock Connect requires the routing of orders across the border of Hong Kong and the PRC. This requires the development of new information technology systems on the part of the SEHK and exchange participants. There is no assurance that these systems will function properly or will continue to
be adapted to changes and developments in both markets. In the event that the relevant systems fail to function properly, trading in A-shares through Stock Connect could be disrupted.
Stock Connect launched on November 17, 2014 and is in its initial stages. The current regulations are untested and there is no certainty as to how they will be applied or interpreted going forward. In addition, the current regulations are subject to change and there can be no assurance that Stock Connect will not be discontinued. New regulations may be issued from time to time by the regulators and stock exchanges in China and Hong Kong in connection with operations, legal enforcement and cross-border trades under Stock Connect. The Fund may be adversely affected as a result of such changes. Furthermore, the securities regimes and legal systems of China and Hong Kong differ significantly and issues may arise based on these differences. In the event that the relevant systems fail to function properly, trading in both markets through Stock Connect could be disrupted and the Fund’s ability to achieve its investment objective may be adversely affected. In addition, the Fund’s investments in A-shares through Stock Connect are generally subject to Chinese securities regulations and listing rules, among other restrictions. Further, different fees, costs and taxes are imposed on foreign investors acquiring A-shares obtained through Stock Connect, and these fees, costs and taxes may be higher than comparable fees, costs and taxes imposed on owners of other securities providing similar investment exposure.
A-Share Market Suspension Risk. A-shares may only be bought from, or sold to, the Fund at times when the relevant A-shares may be sold or purchased on the relevant Chinese stock exchange. The A-shares market has a higher propensity for trading suspensions than many other global equity markets. Trading suspensions in certain stocks could lead to greater market execution risk and costs for the Fund. The SSE currently applies a daily price limit, set at 10%, of the amount of fluctuation permitted in the prices of A-shares during a single trading day. The daily price limit refers to price movements only and does not restrict trading within the relevant limit. There can be no assurance that a liquid market on an exchange will exist for any particular A-share or for any particular time.
