The Space Foundation Index is a modified market capitalization weighted index of representative space companies listed on U.S. market exchanges. Companies were selected based upon an evaluation of several criteria, including percentage of revenues attributable to space-related products and services, market capitalization, trading volume,and which U.S. exchange the securities or ADRs were listed on.

Consideration was also given to providing diverse representation across various space-related markets. Space revenues include launch vehicle, satellite, and related ground segment manufacturing of components and systems; satellite communication services and capacity leasing; space-related positioning and remote sensing data and services and related equipment (including GPS chipsets); and space-related software, operations, and support services.

Space revenue estimates were based upon a review of multiple sources, including Space News' Top 50 lists, company Web sites, SEC filings, as well as internal experience.

The index was prepared by ISDR Consulting, LLC on behalf of the Space Foundation. It was initiated with a level of 100 as of June 30, 2005. Changes in the index value were driven by changes in the market capitalization of the component companies (price multiplied by number of shares outstanding of each company). The contributions of certain component companies' market capitalization to the index were discounted to adjust for lower percentage of revenues attributable to space-related products and services. The level of the index was not directly altered by stock splits, stock dividends, or trading halts, nor was it affected by new listings, additional issuances, delistings, or suspensions.
