Settlement of Certain Litigation and Supplemental Information to the Definitive Proxy Statement

As previously announced, on June 2, 2016, Colony Capital, Inc., a Maryland corporation (“Colony”), entered into an Agreement and Plans of Merger, as amended from time to time, with NorthStar Asset Management Group Inc., a Delaware corporation (“NSAM”) and NorthStar Realty Finance Corp., a Maryland corporation (“NRF”), and certain subsidiary entities of NSAM and NRF, pursuant to which NSAM, Colony and NRF will combine in an all-stock merger of equals (the “Mergers”). In connection with the Mergers, each of NSAM, Colony and NRF has filed a definitive joint proxy statement with the U.S. Securities and Exchange Commission (the “SEC”) on November 18, 2016, which was supplemented by the Current Report on Form 8-K filed with the SEC by each of NSAM and NRF on November 23, 2016 (the “Definitive Proxy Statement”).

As previously described in the Definitive Proxy Statement, a purported stockholder of Colony filed a putative class action complaint in the United States District Court of the District of Maryland (referred to as the Carter action) against Colony and the members of the Colony board. The complaint alleges, among other things, that the initial joint proxy statement/prospectus and the first amendment thereto filed in respect of the Mergers omit or misstate various facts concerning the financial analyses performed by the financial advisors to Colony. Also as noted in the Definitive Proxy Statement, substantially similar claims were filed against NSAM, NRF and their respective boards of directors.

On December 9, 2016, Colony entered into a Memorandum of Understanding with the plaintiff in the Carter action providing for the settlement of the Carter action (the “Colony Memorandum of Understanding”). In the Colony Memorandum of Understanding, Colony agreed to make certain supplemental disclosures to the Definitive Proxy Statement solely for the purposes of minimizing the time, burden, and expense of litigation. The Colony Memorandum of Understanding provides that, in exchange for making these disclosures, defendants will receive, after notice to potential class members and upon court approval, a customary release of claims relating to the Mergers. Similar settlements in principle have been reached in the related litigations against NSAM, NRF, and their respective boards of directors.

Colony believes that no additional disclosure is required to supplement the Definitive Proxy Statement under applicable laws. However, to minimize the costs, risks and uncertainties inherent in litigation and to avoid any potential delay of the consummation of the Mergers, and without admitting any liability or wrongdoing, Colony has agreed, pursuant to the Colony Memorandum of Understanding, to make certain supplemental disclosures to the Definitive Proxy Statement as set forth below.

The supplemental disclosure to the Definitive Proxy Statement set forth in this Current Report on Form 8-K should be read in conjunction with the Definitive Proxy Statement, which should be read in its entirety. To the extent that information in this Current Report on Form 8-K differs from information contained in the Definitive Proxy Statement, the information in this Current Report on Form 8-K shall supersede such information contained in the Definitive Proxy Statement. Defined terms not defined herein have the meanings set forth in the Definitive Proxy Statement. Underlined text shows text being added to a referenced disclosure in the Definitive Proxy Statement in the case of an amended and restated disclosure.

Supplemental Information to the Definitive Proxy Statement

The following disclosure supplements and restates the third sentence of the first full paragraph on page 176 of the Definitive Proxy Statement in the section entitled “The Mergers—Certain Unaudited Prospective Financial Information of NSAM”:

The NSAM Standalone Projections include certain non-GAAP financial measures, such as Net Revenues, EBITDA and CAD (each as defined below).

The following disclosure supplements the disclosure in the section entitled “The Mergers—Certain Unaudited Prospective Financial Information of NSAM” beginning on page 175 of the Definitive Proxy Statement:

Set forth in the table below is a reconciliation of NSAM’s projection of CAD (a non-GAAP financial measure), as included in the NSAM Standalone Financial Projections, to Net Income (a GAAP financial measure) for the periods indicated below.

As described in more detail on pages 175 and 176 of the Definitive Proxy Statement, NSAM does not, as a matter of course, publicly disclose long-term projections as to future revenues, earnings or other results given, among other reasons, the uncertainty, unpredictability and subjectivity of the underlying assumptions and estimates. The inclusion of this information in the Definitive Proxy Statement as well as in the supplemental disclosure as set forth in this Current Report on Form 8-K should not be regarded as an indication that the NSAM special committee, the NSAM board, their respective advisors or any other person considered, or now considers, the NSAM Standalone Projections to be material or to be necessarily predicative of actual future results and the NSAM Standalone Projections should not be relied upon as such.

The NSAM Standalone Projections were previously included in the Definitive Proxy Statement. The NSAM Standalone Projections, as supplemented in this Current Report on Form 8-K, were not, as described in more detail in the Definitive Proxy Statement, prepared with a view toward public disclosure or toward complying with GAAP, the published guidelines of the SEC regarding projections and the use of non-GAAP measures or the guidelines established by the American Institute of Certified Public Accountants for the preparation and presentation of prospective financial information.

The following disclosure supplements the disclosure in the section entitled “The Mergers—Certain Unaudited Prospective Financial Information of NRF” beginning on page 205 of the Definitive Proxy Statement:

Set forth in the table below is a reconciliation of NRF’s projection of CAD (a non-GAAP financial measure), as included in the NRF Standalone Financial Projections, to Net Income (a GAAP financial measure) for the periods indicated below. As described in more detail on pages 205 and 206 of the Definitive Proxy Statement, NRF does not, as a matter of course, publicly disclose long-term projections as to future revenues, earnings or other results given, among other reasons, the uncertainty, unpredictability and subjectivity of the underlying assumptions and estimates. The inclusion of this information in the Definitive Proxy Statement as well as in the supplemental disclosure as set forth in this Current Report on Form 8-K should not be regarded as an indication that the NRF special committee, the NRF board, their respective advisors or any other person considered, or now considers, the NRF Standalone Projections to be material or to be necessarily predicative of actual future results and the NRF Standalone Projections should not be relied upon as such.

Set forth in the table below is a reconciliation of Colony’s projection of Core FFO (a non-GAAP financial measure), as included in the Colony Standalone Financial Projections, to Net Income (a GAAP financial measure) for the periods indicated below. As described in more detail on pages 191 and 192 of the Definitive Proxy Statement, Colony does not, as a matter of course, publicly disclose long-term projections as to future revenues, earnings or other results given, among other reasons, the uncertainty, unpredictability and subjectivity of the underlying assumptions and estimates. The inclusion of this information in the Definitive Proxy Statement as well as in the supplemental disclosure as set forth in this Current Report on Form 8-K should not be regarded as an indication that the Colony board, their respective advisors or any other person considered, or now considers, the Colony Standalone Projections to be material or to be necessarily predicative of actual future results and the Colony Standalone Projections should not be relied upon as such.

The section entitled “The Mergers—Opinion of NSAM’s Financial Advisor” beginning on page 166 of the Definitive Proxy Statement is supplemented by adding the following paragraph immediately before the section entitled “The Mergers—Opinion of NSAM’s Financial Advisor—Summary of Material Financial Analysis” on page 168 of the Definitive Proxy Statement:

Following Goldman Sachs’ presentation to the NSAM board on June 2, 2016 (which we refer to as the June 2 Presentation), it was determined that the estimates of levered free cash flows for NSAM for the second quarter through the fourth quarter of 2016 used in the illustrative discounted cash flow analyses of NSAM did not reflect the Forecasts, which resulted in the incorrect calculation of the range of illustrative present values derived from the discounted cash flow analyses, the range of NSAM’s equity percentage of the combined pro forma company resulting from the leveraged discounted cash flow and dividend discount model contribution analysis and the range of implied equity values resulting from the illustrative NSAM’s standalone levered discounted cash flow to illustrative dividend discount model analysis. Goldman Sachs subsequently performed such analyses, as of June 2, 2016, using the corrected estimates and calculations (as corrected, collectively referred to as the “Corrected Estimates and Calculations”). Based upon and subject to the foregoing, Goldman Sachs confirmed to the NSAM board that, had Goldman Sachs performed its financial analyses set forth in the presentation on June 2, 2016 using the Corrected Estimates and Calculations, there would have been no change to the conclusion set forth in the written opinion of Goldman Sachs. Goldman Sachs’ confirmation does not address any circumstances, developments or events occurring after the date of the written opinion of Goldman Sachs, other than in relation to the Corrected Estimates and Calculations, and Goldman Sachs’ opinion set forth in the written opinion of Goldman Sachs is provided only as of such date.

The following disclosure supplements and restates the last full sentence in the section entitled “The Mergers—Opinion of NSAM’s Financial Advisor—Illustrative NSAM Standalone Levered Discounted Cash Flow Analysis” beginning page 170 of the Definitive Proxy Statement:

Goldman Sachs then divided the range of illustrative equity values it derived by the number of fully diluted outstanding shares of NSAM, as provided by management of NSAM. As set forth in the June 2 Presentation, this analysis indicated a range of illustrative present values of $10.41 to $14.04 per share of NSAM common stock, and using the Corrected Estimates and Calculations, this analysis indicated a range of illustrative present values of $10.84 to $14.47 per share of common stock.

The following disclosure supplements and restates the last sentence in the fourth full paragraph and the table immediately thereafter in the section entitled “The Mergers—Opinion of NSAM’s Financial Advisor—Illustrative Contribution Analysis” beginning on page 172 of the Definitive Proxy Statement:

The following disclosure supplements and restates the last sentence in the first full paragraph and the table immediately thereafter in the section entitled “The Mergers—Opinion of NSAM’s Financial Advisor—Comparison of Illustrative NSAM Standalone Levered Discounted Cash Flow Analysis to Illustrative Dividend Discount Model Analysis” beginning on page 173 of the Definitive Proxy Statement:

The chart below illustrates the comparison range of implied equity values for the above analysis as set forth in the June 2 Presentation:

Cautionary Statement Regarding Forward-Looking Statements

This current report may contain forward-looking statements within the meaning of the federal securities laws. Forward-looking statements relate to expectations, beliefs, projections, future plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts. In some cases, you can identify forward-looking statements by the use of forward-looking terminology such as “may,” “will,” “should,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” or “potential” or the negative of these words and phrases or similar words or phrases which are predictions of or indicate future events or trends and which do not relate solely to historical matters. Forward-looking statements involve known and unknown risks, uncertainties, assumptions and contingencies, many of which are beyond our control, and may cause actual results to differ significantly from those expressed in any forward-looking statement. Among others, the following uncertainties and other factors could cause actual results to differ from those set forth in the forward looking statements: the failure to receive, on a timely basis or otherwise, the required approvals by NSAM, Colony and NRF stockholders, governmental or regulatory agencies and third parties; the risk that a condition to closing of the merger may not be satisfied; each company’s ability to consummate the merger; operating costs and business disruption may be greater than expected; the ability of each company to retain its senior executives and maintain relationships with business partners pending consummation of the merger; the ability to realize substantial efficiencies and synergies as well as anticipated strategic and financial benefits; and the impact of legislative, regulatory and competitive changes. The foregoing list of factors is not exhaustive. Additional information about these and other factors can be found in each company’s reports filed from time to time with the SEC, including NSAM’s and NRF’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2016 and Colony’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2016. There can be no assurance that the merger will in fact be consummated.

We caution investors not to unduly rely on any forward-looking statements. The forward-looking statements speak only as of the date of this report. None of NSAM, Colony or NRF is under any duty to update any of these forward-looking statements after the date of this report, nor to conform prior statements to actual results or revised expectations, and none of NSAM, Colony or NRF intends to do so.
