So with that, we’ll kind of move into the presentation. We’re going to do today the company overview that I’ll walk through; George will do an operations review; Howard will do a financial update; Tom an investment review. And then we’ll spend some time going through each of the regional operations against give you a sense of what we are looking at over the next couple of years, I have a couple of wrap up comments and then certainly the floor will be opened up for Q&A. But during any of the presentations, please feel free to raise your hands, and if you can’t see one of the numbers on the screen, I know the light reflecting here somewhat challenging at times, please raise your hands.
So I’m looking at the overall company review, most of you already know the story, watched the story and our game plans towards amplify those parts for you. But the real focus we have as an organization is from an operational standpoint the focus is clearly on dominant market share, quality sub market positioning, we think that drives both near-term value, but also long-term competitive advantage. And then as we phrase it a best of market infrastructure, which relates to our products, our people in the service platform that we have tenant to our entire asset base.
This gives you a little bit of a snapshot of Brandywine portfolio you can see we have 283 buildings, sold-out 32 million square feet including our joint venture properties. Our overall core portfolio of occupancy is 87%, which is on its past even higher numbers as we look at over the next couple of years. We are just shy of 89% leased. Then we’ve also showed in the far right-hand column, the revenue contributions. Now couple of interesting points, if you go back three and a half years, the revenue contributions from Philadelphia CBD was about 12%. We have more than doubled that in the last three and a half years through some of the acquisitions we’ve made downtown including this building right here.
