Slide 20 We have not reconciled the non-GAAP EPS guidance to the most directly comparable GAAP measure because this cannot be done without unreasonable effort.

In Process figures include Long-Term Operating Assets (LTOA) of $0.3 billion for Q2 14, $0.9 billion for Q4 13, $1.2 billion for Q4 12 and $1.5 billion for Q4 11. LTOA are projects that have achieved a stabilized level of occupancy or have been held 18-24 months following shell completion or acquisition. Pipeline deals are those projects we are pursuing which we believe have a greater than 50% chance of closing or where land has been acquired and the projected construction start is more than twelve months out. Slide 7 Excludes deal costs, deferred consideration and / or earnouts. As of July 31, 2014 we have paid $40 million of deferred consideration for Norland. Acquisition also includes 362,916 shares of common stock issued to Norland senior management, the value of which is not included in this figure. For fiscal year ended April 5, 2013. Excludes deal costs, deferred consideration and / or earnouts. Annual revenue approximations are based on revenues at the time of purchase.

DISCONTINUED OPERATIONS Discontinued Operations (Slides 8, 9, 10, 21, 24 and 25) Under GAAP, the Company has historically classified most of its gains on dispositions of consolidated real estate as income from discontinued operations rather than as revenue and earnings from continuing operations. The Company’s Development Services segment, and occasionally its Global Investment Management segment, are engaged in developing and selling real estate projects in the normal course of business. Management believes that the characterization of these gains as income from discontinued operations may create the inaccurate impression that the Company is exiting this business. Effective January 1, 2014, CBRE adopted new GAAP accounting standards that no longer require us to report dispositions of real estate as income from discontinued operations. Revenue from discontinued operations totaled: $1.3 million for the year ended December 31, 2008, $3.9 million for the year ended December 31, 2010, $6.7 million for the year ended December 31, 2011, $5.7 million for the year ended December 31, 2012, $9.4 million for the year ended December 31, 2013 and $0.5 million for the twelve months ended June 30, 2014. EBITDA related to discontinued operations totaled: $16.9 million for the year ended December 31, 2008, $16.4 million for the year ended December 31, 2010, $14.1 million for the year ended December 31, 2011, $5.6 million for the year ended December 31, 2012, $7.9 million for the year ended December 31, 2013 and $0.5 million for the twelve months ended June 30, 2014.
