On Tuesday, chief financial officer (CFO) of search and technology major Google, Patrick Pichette, said that he has planned to retire from his job. It will be the latest change in a series of changes in the Internet company's management level. According to some analysts, Pichette's resign will not cause major disruptions in the company.

The 52-year-old French Canadian posted his decision to leave the job on his Google+ Web page on Tuesday. In a regulatory filing with the United States Securities and Exchange Commission, Google confirmed Pichette's resignation and said that the company, which dominates the online advertising business, will find its current CFO's replacement within six months. Pichette has not revealed anything about the retirement date. Google said that the CFO will help the company in finding a successor.

After news of Pichette's retirement surfaced, shares of the company fell about 2.4% and closed at about $555.01. Pichette's decision to retire came as a surprise to investors. Daniel Ernst, analyst at Hudson Square Research, said that the CFO's decision after about seven years at the California headquartered company appeared logical. According to Ernst, Google is a massive Internet company that could generate more than $75 billion in revenue in 2015 and exit of CFO could hurt investor sentiment.

For the company, Pichette's retirement is the latest change in the company's upper ranks. In 2014, Nikesh Arora, Chief Business Officer of Google, had left the company unexpectedly and became vice chairman of Japan's SoftBank Corp. Vic Gundotra, the head of Google's social networking services, left the company in 2014.

In the blog post, Pichette said that his decision to retire came after a trip to Africa's Mount Kilimanjaro when his wife asked him to continue travelling. He further wrote, "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".
