According to the S1 filing, this was the criteria for disclosing:

* each stockholder known by us to be the beneficial owner of more than 5% of our outstanding shares of Class A common stock or Class B common stock;

* each of our directors;

* each of our named executive officers;

* all of our directors and executive officers as a group; and

* all selling stockholders.

It's safe to say Eduardo doesn't fit into buckets 2-4, so as long as he doesn't own at least 5% or isn't selling stock as part of the IPO, he wouldn't need to be disclosed.
