Why is the number of issued shares less than the number of outstanding shares
I have been asking myself a similar question about the financial statements of Weyerhaeuser. In response to Dheer's comment, whilst treasury shares are treated as a negative, it is issued shares less treasury shares (the negative) which gives the outstanding shares. So the original query remains unanswered. I've searched several sources and all state that outstanding shares will never be greater than issued shares.  I've realized that the shares referred to are those authorized followed by those issued and outstanding (current year and prior year respectively) i.e. the shares that are both issued and outstanding as they must be issued in order to be outstanding This is supported in the example of Weyerhaeuser as there was a large increase in shares during Q1 2016 as a result of their merger with Plum Creek. Shares issued and outstanding are 510 million and 759 million respectively.
