The change was first spotted in an SEC filing and Pichette soon followed up with an announcement on Google Plus. In the announcement, Pichette, who has been with Google since 2008, explained the reasons behind his retirement.

Says Pichette:

After nearly 7 years as CFO, I will be retiring from Google to spend more time with my family. Yeah, I know you've heard that line before. We give a lot to our jobs. I certainly did. And while I am not looking for sympathy, I want to share my thought process because so many people struggle to strike the right balance between work and personal life.

Pichette goes on to explain his desire to travel the world with his wife, Tamar, is why he ultimately decided to retire:

Allow me to spare you the rest of the truths. But the short answer is simply that I could not find a good argument to tell Tamar we should wait any longer for us to grab our backpacks and hit the road - celebrate our last 25 years together by turning the page and enjoy a perfectly fine mid life crisis full of bliss and beauty, and leave the door open to serendipity for our next leadership opportunities, once our long list of travels and adventures is exhausted.

Pichette's exact departure date is unknown, but he notes that the transition will occur over the next several months as Google finds his replacement and he has a chance to bring him or her up to speed.
