Please explain why the funds have significant investment in a single sector and/or country. Please explain whether additional sector and/or country specific disclosure should be included in the “Principal Investment Strategies” section of the related prospectuses.

The funds’ recent significant sector holdings are consistent with the recent weightings of those sectors in the respective funds’ indices. Sector specific disclosure is not included in the “Principal Investment Strategies” section of the funds’ prospectuses because the funds do not have principal investment strategies associated with investments in a particular sector. The funds do not invest >25% of their total assets in a single industry as a matter of fundamental policy, however their sector exposure can and does fluctuate. Similarly, the funds’ benchmark indices are not sector-specific and their sector exposure fluctuates.

Certain of the funds listed above have a name that references a specific country or region (e.g., Fidelity Canada Fund, Fidelity Emerging Asia Fund). In accordance with Rule 35d-1 of the Investment Company Act, each of these funds has adopted a policy to invest at least 80% of the value of its portfolio in investments tied economically to the particular country or geographic region referenced in the fund’s name. Country specific disclosure is included in the “Principal Investment Strategies” section of these funds’ prospectuses.
