---- Disclosure of Financial Relationships for David H. Reiley ----

I currently work for Google, Inc., a company that earns substantial revenue from online advertising. I previously worked for Yahoo!, another online-advertising company, during the time that most of the work was done.

It is a matter of personal integrity for me to do unbiased scientific research to the best of my ability. I am grateful to Yahoo! and Google for affording me the opportunity to do this; I would not have left academia otherwise, because I care too much about learning the truth.
