Why This Deal Matters It fulfills our 20-year objective of being the premier, #1 firm in each of our six primary business lines. It accelerates our objective to further balance our earnings between transactional and contractual business. Like each transformative acquisition before it, our “best athlete” philosophy allows for a significant enhancement to our already best in class human capital. The transaction adds over $55 billion in assets under management (AUM), which will produce significant and recurring services revenues. It proves our ability to out-compete some of the most formidable investment firms in the world. It creates the premier real estate investment management company in Europe, the U.S. and Asia Pacific.
