Fidelity Flex International Index Fund

POST-EFFECTIVE AMENDMENT NO. 605

"Investment Details" (prospectus)

"Principal Investment Strategies"

"The Fidelity Global ex U.S. Index<sup>SM</sup> is a float-adjusted market capitalization-weighted index designed to reflect the performance of stocks of non-U.S. large- and mid-capitalization companies.

C:

The Staff requests we expand the principal investment strategies discussion to describe the liquidity and investability requirements that are part of the index methodology.

R:

Fidelity's rules-based proprietary index methodology for the fund is described in plain

English in the "Fund Basics" section under "Principal Investment Strategies." In addition, the

"Appendix" section of the fund's prospectus notes that "[a]dditional information regarding the

index or indices is available on i.fidelity.com/indices." This website contains the complete index methodology. Accordingly, we do not believe additional disclosure is needed.
