Following eight straight weeks of profiling top-notch CEOs, the time has officially come for you and other members of The Motley Fool community to decide who is the best CEO in 2012.

The methodology behind the voting is simple. Similar to an NCAA-style basketball bracket, the eight CEOs will be pitted into four match-ups that the community will have one week to vote on. Next week we'll release the results of the previous week's voting, and the remaining four CEOs will again be bracketed for voting. Voting will continue over the next couple of weeks until we have a winner, which will be unveiled at the beginning of December.

As you can see, the ball really is in your court and you do have a say in who merits the coveted title of The Motley Fool's chosen CEO of the year. Below the voting bracket I've included a quick synopsis of the match-up; however, I encourage you to revisit the nomination article for a more complete explanation of why that particular CEO was nominated for this award.

The CAPS darlings: Apple (AAPL -0.23%) vs. Arena Pharmaceuticals (ARNA)
This match-up will pit two of The Motley Fool community's favorites against each other: Apple's Tim Cook and Arena's Jack Lief. Apple has been doing what it does best in 2012: blowing away the competition. At one point becoming the biggest company in history, Apple has now amassed a cash pile of $121 billion and has instituted a $10.60 annual dividend. Arena isn't profitable yet, but it's graced shareholders with a 347% jump in its share price thanks to its potential anti-obesity blockbuster Belviq. Which CAPS darling moves on? That's up to you! Cast your vote below.
