A recent filing with the United States Securities and Exchange Commission reveals that newly appointed Yahoo (YHOO) CEO Marissa Mayer will potentially earn $100 million over the next five years. The sum is undoubtedly huge, but the tasks that lie ahead for Yahoo’s new chief are daunting at best. Now that Mayer has taken the reins, the world — or, perhaps more accurately, Yahoo employees and investors — waits with bated breath to see what sweeping changes might come under Mayer’s rule. The answer, for the time being, is none. “Please do not stop. You are doing important work. Please don’t stop,” Mayer told Yahoos in a memo obtained by All Things D. “If you have questions or concerns about whether to continue or not, please ask. However, with the exception of a few things that might heavily constrain us in the future, the answer is most likely: ‘Yes, keep moving.’ ” The rest of the memo is linked below, just beyond an interstitial ad.
