Previously, I had mentioned that Twitter had filed a registration statement for its initial public offering. The initial batch of Twitter contracts was missing the offer letters. A subsequent filing included offer letters for Adam Bain, Ali Rowghani, Christopher Fry, Mike Gupta, Richard Costolo and Vijaya Gadde.
Cortina Systems Inc. had filed a Form S-1 Registration Statement back in March 2011. They withdrew their registration in September 2012. The Cortina Systems Inc. contracts included mostly offer letters.
500.com Ltd., an online sports lottery service provider in China, filed a Form F-1 Registration Statement in October 2013. I added their agreements to the website.
