Social game giant Zynga has attracted plenty of attention over the last several months, particularly as it geared up for its major IPO late last year. As a result, CEO Mark Pincus has had to deal with a handful of security concerns, and his company spent more than $1.37 million in fiscal 2011 to keep him and his family safe.

While it's relatively common for companies to invest money into protecting their executives, Zynga's figure is fairly high relative to other large companies, reports MarketWatch. The security funds reached this lofty sum since Zynga recently had to protect Pincus from an alleged stalker.

In early 2011, Pincus filed for a restraining order against this individual, and he has since worked to settle the conflict in court. Zynga has not confirmed whether it will need to invest more money to protect its CEO.
