Summary

The file was originally vectorized, and placed on an appropriate background by user grmike who used the first page of the company's 2008 annual report http://files.shareholder.com/downloads/ALXN/0x0x290266/10BFB823-6119-4446-8140-FE8DDE706191/2008_Annual_Report.pdf archive copy at the Wayback Machine as the source of the basic form and the background (extracted as bitmap then vectorized). the logo agrees with what is used at the company's webpage http://www.alxn.com/AboutUs/Default.aspx archive copy at the Wayback Machine though the background colors seem a bit different each division of the company uses a different color.
