Total revenues for the year ended December 31, 2015 were $689.1 million, compared to $572.2 million for the same period in the prior year, an increase of $116.9 million, or 20.4%. Total operating expenses for the year ended December 31, 2015 were $574.4 million compared to $487.6 million for the same period in the prior year, representing an increase of $86.8 million, or 17.8%. Cost of services as a percent of total revenues rose slightly to 61.4% compared to 61.2% for the same period in the prior year.

Fourth-Quarter 2015 Results Compared to Fourth-Quarter 2014

Total revenues for the fourth-quarter of 2015 were $203.2 million, compared to $172.4 million for the same period in the prior year, an increase of $30.7 million, or 17.8%. The growth in total revenues was primarily a result of increases in revenues from real estate brokerage commissions which rose to $186.2 million for the three months ended December 31, 2015 from $156.7 million for the same period in the prior year, for an increase of 18.8%. This improvement was driven by a combination of the growth in the number of investment sales transactions and average commission rates. The rise in average commission rates reflects a higher proportion of private client market segment transactions ($1-$10 million) as compared to the middle and institutional market segment transactions (>$10 million). Private client market segment ($1-$10 million) transactions generally earn a higher commission rate. Growth in financing fees and other revenues, contributed the remaining increase in total revenues.

Total operating expenses for the fourth-quarter of 2015 were $169.2 million, compared to $145.3 million for the same period in the prior year, rising by $23.9 million, or 16.4%. The increase was primarily driven by a $19.8 million, or 18.1%, rise in cost of services, which are variable commissions paid to the Company’s investment sales professionals and compensation-related costs in connection with our financing activities. Cost of services as a percent of total revenues remained relatively consistent at 63.8% compared to 63.7% for the same period in the prior year.

Selling, general and administrative expense rose by $3.9 million, or 11.4% during the fourth-quarter of 2015 as compared to the same period in the prior year. The increase was primarily due to (i) salaries and related benefits as a result of increases in corporate and office support in connection with our growth; (ii) management performance-related compensation driven by our operating results; (iii) facilities expenses due to office expansion and (iv) other expense categories, net primarily driven by our expansion and growth. These costs were partially offset by lower stock-based compensation expense and legal costs and accruals.

Net income for the fourth-quarter of 2015 was $19.9 million or $0.51 per common share (basic and diluted) compared to net income of $16.4 million or $0.42 per common share (basic and diluted) for the same period in the prior year. Adjusted EBITDA for the fourth-quarter of 2015 was $35.3 million compared to adjusted EBITDA of $29.7 million for the same period in the prior year.

Subsequent Events

On March 1, 2016, the Company announced that its Chief Executive Officer, John J. Kerin, would be retiring effective March 31, 2016 and will be succeeded by Hessam Nadji, currently its Senior Executive Vice President. On March 31, 2016, Mr. Nadji will also be appointed to the Company’s board of directors.

Business Outlook

The Company is well-positioned to leverage its private client dominant brand, experienced management team, investments in infrastructure, tools and technology to build on its recent success. The private client market segment ($1-$10 million) continues to be a pillar of the Company’s business with opportunities for continued market share gains. Commercial real estate yields and relative stability should continue to result in transactional activity albeit at lower levels of growth. This is driven by the maturing of the cycle, recent capital markets volatility and extended marketing and closing timelines. The Company’s strong 2015 performance makes year-

over-year comparisons challenging, even with solid underlying property fundamentals, and historically low interest rates.

Adjusted EBITDA Reconciliation

Adjusted EBITDA, which the Company defines as net income before interest income/expense, taxes, net realized gains on marketable securities, available-for-sale, depreciation and amortization and stock-based compensation is a non-GAAP financial measure. The Company uses Adjusted EBITDA in its business operations to, among other things, evaluate the performance of its business, develop budgets and measure its performance against those budgets. The Company also believes that analysts and investors use Adjusted EBITDA as a supplemental measure to evaluate its overall operating performance. However, Adjusted EBITDA has material limitations as an analytical tool and should not be considered in isolation or as a substitute for analysis of the Company’s results as reported under U.S. generally accepted accounting principles (“U.S. GAAP”). The Company finds Adjusted EBITDA as a useful tool to assist in evaluating performance because it eliminates items related to capital structure and taxes and non-cash stock-based compensation charges. In light of the foregoing limitations, the Company does not rely solely on Adjusted EBITDA as a performance measure and also considers its U.S. GAAP results. Adjusted EBITDA is not a measurement of the Company’s financial performance under U.S. GAAP and should not be considered as an alternative to net income, operating income or any other measures derived in accordance with U.S. GAAP. Because Adjusted EBITDA is not calculated in the same manner by all companies, it may not be comparable to other similarly titled measures used by other companies.

A reconciliation of the most directly comparable U.S. GAAP financial measure, net income, to Adjusted EBITDA is as follows (in thousands):
