"Giving effect to a private placement of common stock completed in October 2011, the Company's cash and short term investments on a pro forma basis totaled $85.6 million at September 30, 2011, compared to $86.2 million at June 30, 2011."

Sorry, but I find this a bit confusing. Why would they mention the placement, which was completed in October, as having effect on the financial position at the end of September?

I am lost on this sentence.
