Charlie Munger in 2007 quoted the importance of an Investment Checklist in Berkshire Hathaways Annual Letter, “I’m a great believer in solving hard problems by using a checklist. You need to get all the likely and unlikely answers before you; otherwise it’s easy to miss something important.”

Therefore, below is my current Investment checklist which, every company or marketable security must be ‘washed through’ before an investment can be made. It is certain that this checklist will be added to as investing mistakes are encountered and lessons are learned from others overtime.

Checklist questions
