AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

1. | Basis of Presentation and Use of Estimates

The Consolidated Financial Statements of Affiliated Managers Group, Inc. (the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for full year financial statements. In the opinion of management, all normal and recurring adjustments considered necessary for a fair presentation of the Company’s financial position and results of operations have been included and all intercompany balances and transactions have been eliminated. During the second quarter of 2017, the Company changed its Consolidated Statement of Income presentation to include Income from equity method investments in Operating income, as its equity method Affiliates are integral to the Company’s operations. This change, along with other reclassifications, has been made to the prior period’s financial statements to conform to the current period’s presentation. Operating results for interim periods are not necessarily indicative of the results that may be expected for any other period or for the full year. The Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016 includes additional information about its operations, financial position and accounting policies, and should be read in conjunction with this Quarterly Report on Form 10-Q.
The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.
All amounts in these notes, except per share data in the text and tables herein, are stated in millions unless otherwise indicated.

2. | Recent Accounting Developments

Effective January 1, 2017, the Company adopted Accounting Standard Update (“ASU”) 2016-07, Investments - Equity Method and Joint Ventures: Simplifying the Transition to the Equity Method of Accounting, and ASU 2016-06, Derivatives, and Hedging: Contingent Put and Call Options in Debt Instruments. The adoption of these updates did not have a significant impact on the Company’s Consolidated Financial Statements.
In May 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU 2014-09, Revenue from Contracts with Customers, and subsequently issued several related amendments. The standard provides a comprehensive model for revenue recognition and is effective for the Company and its consolidated Affiliates for interim and annual periods beginning after December 15, 2017 and for interim and annual periods beginning after December 15, 2018 for the Company’s equity method Affiliates. The standard may be adopted using either the full or modified retrospective method. The Company has not yet selected its transition method and continues to evaluate the impact of this standard on its Consolidated Financial Statements, but it does not expect the adoption to significantly impact the timing of the recognition of its Revenue. The Company is evaluating whether certain costs currently expensed as incurred meet the criteria for capitalization and whether certain revenue-related costs will be presented on a gross or net basis.
In January 2016, the FASB issued ASU 2016-01, Fair Value: Recognition and Measurement of Financial Assets and Liabilities. Under the new standard, all equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) will generally be measured at fair value with any changes recognized through earnings. The standard is effective for interim and annual periods beginning after December 15, 2017 and must be adopted using a modified retrospective method. The impact of this standard on the Company’s Consolidated Financial Statements will depend on the equity investments held by the Company at the time of adoption.
In February 2016, the FASB issued ASU 2016-02, Leases, which requires lessees to recognize assets and liabilities arising from most operating leases on the statement of financial position. The standard is effective for interim and annual periods beginning after December 15, 2018 for the Company and its consolidated Affiliates and for interim and annual periods beginning after December 15, 2019 for the Company’s equity method Affiliates. The standard must be adopted using a modified retrospective method. The Company is evaluating the impact of this standard on its Consolidated Financial Statements.

Fair Value | $ | 81.9 |  |  | $ | 41.3 |  |  | $ | 40.5 |  |  | $ | 51.1 |

In the three and nine months ended September 30, 2016, the Company received proceeds of $12.6 million and $47.0 million, respectively, from the sale of investments classified as available-for-sale and recorded gains of $6.2 million and $15.4 million, respectively. In the three and nine months ended September 30, 2017, the Company received proceeds of $15.4 million and $58.7 million, respectively, from the sale of investments classified as available-for-sale and recorded gains of $7.4 million and $19.2 million, respectively. There were no significant realized gains or losses on investments classified as trading in the three and nine months ended September 30, 2016. In the three and nine months ended September 30, 2017, the Company received proceeds of $8.2 million and $23.2 million, respectively, from the sale of investments classified as trading and recorded net gains of $1.7 million and $5.0 million, respectively. The realized gains and losses on securities held in Affiliate sponsored consolidated products were recorded in Other operating expenses (net), other realized gains and losses were recorded in Investment and other income.

4. | Investments in Affiliates and Affiliate Sponsored Investment Products

Investments in Affiliates
The Company’s Affiliates are consolidated or accounted for under the equity method, depending upon the underlying structure of and relationship with each Affiliate.
A limited number of the Company’s Affiliates are considered voting rights entities (“VREs”) because the total equity investment at risk is sufficient to enable the entities to finance their respective activities independently and each entity’s equity holders have the right to receive residual returns, the obligation to absorb losses and the right to direct the activities of the entity
9

AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
that most significantly impact its economic performance. Most of the Company’s Affiliates considered VREs are accounted for under the equity method because the Company lacks control, but is deemed to have significant influence.
Substantially all of the Company’s Affiliates are considered variable interest entities (“VIEs”) because they are structured as partnerships (or similar entities) and the limited partners lack substantive kick-out or substantive participation rights over the general partner. The Company consolidates a VIE when it is the primary beneficiary of the entity, which is defined as having the power to direct the activities that most significantly impact the VIE’s economic performance and the right to receive benefits from or the obligation to absorb losses of the entity that could potentially be significant to the VIE. The Company applies the equity method of accounting to a VIE when it is not the primary beneficiary, but is deemed to have significant influence.
The unconsolidated assets, net of liabilities and non-controlling interests of equity method Affiliates considered VIEs, and the Company’s maximum risk of loss were as follows:

| December 31, 2016 |  | September 30, 2017
| Unconsolidated VIE Net Assets |  | Carrying Value and Maximum Exposure to Loss |  | Unconsolidated VIE Net Assets |  | Carrying Value and Maximum Exposure to Loss
Affiliates accounted for under the equity method | $ | 1,047.6 |  |  | $ | 2,846.8 |  |  | $ | 1,019.4 |  |  | $ | 2,749.7 |

Affiliate Sponsored Investment Products
The Company’s consolidated Affiliates sponsor various investment products for which they also act as the investment advisor. These investment products are primarily owned by third-party investors; however, certain products are funded with general partner and seed capital investments from the Company and its Affiliates. Third-party investors are generally entitled to substantially all of the economics of these products.
Certain of the Company’s Affiliate sponsored investment products are considered VIEs because they are structured as partnerships (or similar entities) and the limited partners lack substantive kick-out or substantive participation rights over the general partner. The Company's Affiliates’ involvement with sponsored investment products is generally limited to that of a service provider, and their seed capital investments, if any, represent an insignificant interest in the relevant investment products’ net assets. The Company’s and its consolidated Affiliates’ exposure to risk in these entities is generally limited to any capital contribution made or required to be made and any earned but uncollected management and performance fees. As a result, in most cases these VIEs are not consolidated and are accounted for under the equity method because neither the Company nor its Affiliates are deemed to be the primary beneficiary.
The net assets of Affiliate sponsored investment products that were considered VIEs accounted for under the equity method and the Company’s maximum risk of loss were as follows:

| December 31, 2016 |  | September 30, 2017
| Unconsolidated VIE Net Assets |  | Carrying Value and Maximum Exposure to Loss |  | Unconsolidated VIE Net Assets |  | Carrying Value and Maximum Exposure to Loss
Affiliate sponsored investment products | $ | 1,756.6 |  |  | $ | 9.4 |  |  | $ | 1,961.5 |  |  | $ | 9.9 |

5. | Commitments and Contingencies

From time to time, the Company and its Affiliates may be subject to claims, legal proceedings and other contingencies in the ordinary course of their business activities. Any such matters are subject to various uncertainties, and it is possible that some of these matters may be resolved in a manner unfavorable to the Company or its Affiliates. The Company and its Affiliates establish accruals, as necessary, for matters for which the outcome is probable and the amount of the liability can be reasonably estimated.
Third Avenue Management LLC (“Third Avenue”), one of the Company’s consolidated Affiliates, was named as a defendant in various legal actions relating to the liquidation and closure of the Third Avenue Focused Credit Fund. The Company was named as a co-defendant in one of these actions, as a purported control person. In 2016, Third Avenue recorded
10

AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
a reserve of $15.0 million in connection with the proposed resolution of all claims related to the Focused Credit Fund. These claims, including those against the Company, were subsequently resolved in a court-approved settlement, and Third Avenue and its insurers paid amounts due under the settlement during the quarter and no additional expense was recognized.
The Company has committed to co-invest in certain Affiliate sponsored investment products. As of September 30, 2017, these unfunded commitments were $94.9 million and may be called in future periods.
As of September 30, 2017, the Company was contingently liable, upon the achievement by certain Affiliates of specified financial targets, to make payments related to the Company’s investments in these Affiliates through 2019. For its consolidated Affiliates, the Company was contingently liable for up to $21.7 million, and expected to make payments of $8.9 million ($1.6 million in 2017). The present value of these expected payments was $8.1 million. For its equity method Affiliates, the Company was contingently liable for up to $170.0 million, and expected to make no payments.
Affiliate equity interests provide holders with a conditional right to put their interests to the Company over time. See Note 13. In addition, in connection with an investment in an Affiliate accounted for under the equity method, the Company entered into an arrangement with a minority owner of the Affiliate that gives such owner the right to sell a portion of its ownership interest in the Affiliate to the Company annually beginning in the fourth quarter of 2018. The purchase price of these conditional purchases will be at fair market value on the date of the transaction.
The Company and certain consolidated Affiliates operate under regulatory authorities that require that they maintain minimum financial or capital requirements. Management is not aware of any significant violations of such requirements.

6. | Senior Notes

In the three months ended September 30, 2017, the Company redeemed all $200.0 million principal amount outstanding of its 6.375% senior unsecured notes due 2042 at a redemption price equal to 100% of the principal amount. The notes were subsequently canceled and retired.

__________________________

(1) | Principally investments in equity securities.

(2) | Amounts are presented within Other assets or Other liabilities.

The following are descriptions of the significant financial assets and liabilities measured at fair value and the fair value methodologies used.
Cash equivalents consist primarily of highly liquid investments in daily redeeming money market funds, without enacted liquidity fees or redemption gates that are valued at net asset value (“NAV”).
Investments in marketable securities consist primarily of investments in publicly traded securities and funds advised by Affiliates that are valued at NAV. Publicly traded securities valued using unadjusted quoted market prices for identical instruments in active markets are classified as level 1. Publicly traded securities valued using quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active are classified as level 2. Investments in funds advised by Affiliates that are valued at NAV are classified as level 1.
Contingent payment arrangements represent the present value of the expected future settlement of contingent payment arrangements related to the Company’s investments in consolidated Affiliates. The significant unobservable inputs that are used in the fair value measurement of these obligations are growth and discount rates. Increases in the growth rate result in a higher obligation while increases in the discount rate result in a lower obligation.
Affiliate equity obligations include agreements to repurchase Affiliate equity. The significant unobservable inputs that are used in the fair value measurement of the agreements to repurchase Affiliate equity are growth and discount rates. Increases in the growth rate result in a higher obligation while increases in the discount rate result in a lower obligation.
Foreign currency forward contracts use model-derived valuations in which all significant inputs are observable in active markets to determine fair value.
It is the Company’s policy to value financial assets or liabilities transferred as of the beginning of the period in which the transfer occurs. There were no significant transfers of financial assets or liabilities between level 1 and level 2 in the three and nine months ended September 30, 2016 and 2017.
Level 3 Financial Assets and Liabilities

Investments Measured at NAV as a Practical Expedient
The Company’s Affiliates sponsor investment products in which the Company and Affiliates may make general partner and seed capital investments. The Company uses the NAV of these investments as a practical expedient for their fair value. The following table summarizes the nature of the Company’s investments, unfunded commitments and any related liquidity restrictions or other factors that may impact the ultimate value realized:

___________________________

(1) | The Company uses NAV as a practical expedient one quarter in arrears (adjusted for current period calls and distributions) to determine the fair value. These funds primarily invest in a broad range of private equity funds, as well as making direct investments. Distributions will be received as the underlying assets are liquidated over the life of the funds, which is generally up to 15 years.

(2) | These are multi-disciplinary funds that invest across various asset classes and strategies, including long/short equity, credit and real estate. Investments are generally redeemable on a daily, monthly or quarterly basis.

(3) | Fair value attributable to the controlling interest was $59.9 million and $72.8 million as of December 31, 2016 and September 30, 2017, respectively.

Other Financial Assets and Liabilities Not Carried at Fair Value
The carrying amount of Receivables and Payables and accrued liabilities approximates fair value because of the short-term nature of these instruments. The carrying value of notes receivable, which is reported in Other assets, approximates fair value because interest rates and other terms are at market rates. The carrying value of the credit facilities, which is reported in Senior bank debt, approximates fair value because the debt has variable interest based on selected short-term rates. The following table summarizes the Company’s other financial liabilities not carried at fair value:

A prior owner of one of the Company’s Affiliates retained an interest in certain of the Affiliate’s private equity investment partnerships. The prior owner’s interest is presented in the Company’s Consolidated Balance Sheets as either a liability in Other liabilities or as Non-controlling interests, depending on the structure of the prior owner’s investments in the partnerships. The total liability was $67.8 million and $64.1 million at December 31, 2016 and September 30, 2017, respectively. The total non-controlling interest was $2.5 million and $0.8 million at December 31, 2016 and September 30, 2017, respectively.
The Company and its Affiliates earn asset based revenue, performance fees, distribution and servicing and other fees and incur distribution and servicing and other expenses for services provided to Affiliate sponsored investment products. In addition, Affiliate management owners and Company officers may serve as trustees or directors of certain investment vehicles from which an Affiliate earns revenue.
The Company has liabilities to related parties for contingent payment arrangements in connection with certain business combinations. The net present value of the total amounts payable were $8.6 million and $8.1 million as of December 31, 2016 and September 30, 2017, respectively, and were included in Other liabilities.
The Company has related party transactions in association with its Affiliate equity transactions, as more fully described in Notes 12 and 13.

For the nine months ended September 30, 2016 and 2017, the Company granted awards with fair values of $28.0 million and $36.7 million, respectively. These awards were valued based on the closing price of the Company’s common stock on the grant date and contain vesting conditions requiring service over a period of three to four years. In certain circumstances, awards also require certain performance conditions to be satisfied.

12. | Redeemable Non-Controlling Interests

Affiliate equity interests provide holders with a ratable portion of ownership in one of the Company’s consolidated Affiliates, consistent with the structured partnership interests in place at the respective Affiliate. Affiliate equity holders generally have a conditional right to put their interests to the Company at certain intervals (between five and 15 years from the date the equity interest is received or on an annual basis following an Affiliate equity holder’s departure). The current redemption value of the Company’s Affiliate equity interests is presented as Redeemable non-controlling interests. Changes in the current redemption value are recorded to Additional paid-in capital. The following table presents the changes in Redeemable non-controlling interests:

|  | Redeemable Non-controlling interests
Balance, as of December 31, 2016 |  | $ | 673.5 |
Changes attributable to consolidated products |  | 9.5 |
Repurchases of redeemable Affiliate equity |  | (151.6 | )

13. | Affiliate Equity

Affiliate equity interests are allocated income in a manner that is consistent with the structured partnership interests in place at the respective Affiliate. The Company’s Affiliates generally pay quarterly distributions to Affiliate equity holders. For the nine months ended September 30, 2016 and 2017, distributions paid to Affiliate equity holders were $270.1 million and $266.8 million, respectively.
The Company periodically repurchases Affiliate equity interests from and issues Affiliate equity interests to its Affiliate equity holders. For the nine months ended September 30, 2016 and 2017, the amount of cash paid for repurchases was $82.1 million and $121.3 million, respectively. For the nine months ended September 30, 2016 and 2017, the total amount of cash received for issuances was $11.8 million and $8.8 million, respectively.
Sales and repurchases of Affiliate equity generally occur at fair value; however, the Company also grants Affiliate equity to its Affiliate partners, employees and officers as a form of compensation. If the equity is issued for consideration below the fair value of the equity or repurchased for consideration above the fair value of the equity, then such difference is recorded as compensation expense over the requisite service period.
The following is a summary of Affiliate equity expense:

| For the Three Months Ended September 30, |  | For the Nine Months Ended September 30,
| 2016 |  | 2017 |  | 2016 |  | 2017
Controlling interest | $ | 3.2 |  |  | $ | 2.3 |  |  | $ | 7.7 |  |  | $ | 9.4 |
Non-controlling interests | 18.5 |  |  | 7.7 |  |  | 27.2 |  |  | 29.2 |
Total | $ | 21.7 |  |  | $ | 10.0 |  |  | $ | 34.9 |  |  | $ | 38.6 |

The following is a summary of unrecognized Affiliate equity expense:

| Controlling Interest |  | Remaining Life |  | Non-controlling Interests |  | Remaining Life
December 31, 2016 | $ | 31.3 |  |  | 4 years |  | $ | 70.7 |  |  | 5 years
September 30, 2017 | 33.0 |  |  | 4 years |  | 82.5 |  |  | 5 years

The Company records amounts receivable from and payable to Affiliate equity holders in connection with the transfer of Affiliate equity interests that have not settled at the end of the period. The total amount receivable was $22.9 million and $10.9 million at December 31, 2016 and September 30, 2017, respectively, and was included in Other assets. The total amount payable was $12.1 million and $45.7 million as of December 31, 2016 and September 30, 2017, respectively, and was included in Other liabilities.
Effects of Changes in the Company’s Ownership in Affiliates
The Company periodically acquires interests from, and transfers interests to, Affiliate equity holders. Because these transactions do not result in a change of control, any gain or loss related to these transactions is recorded to Additional paid-in capital, which increases or decreases the controlling interest’s equity. No gain or loss related to these transactions is recognized in the Consolidated Statements of Income or Comprehensive Income.
While the Company presents the current redemption value of Affiliate equity within Redeemable non-controlling interests with changes in the current redemption value increasing or decreasing the controlling interest’s equity over time, the following table discloses the cumulative effect that ownership changes had on the controlling interest’s equity related only to Affiliate equity transactions that settled during the periods:

15. | Earnings Per Share

The calculation of basic earnings per share is based on the weighted average number of shares of the Company’s common stock outstanding during the period. Diluted earnings per share is similar to basic earnings per share, but adjusts for the dilutive effect of the potential issuance of incremental shares of the Company’s common stock. The following is a reconciliation of the numerator and denominator used in the calculation of basic and diluted earnings per share available to common stockholders.

Average shares outstanding (diluted) in the table above exclude share awards that have not satisfied performance conditions and the anti-dilutive effect of the following shares:

| For the Three Months Ended September 30, |  | For the Nine Months Ended September 30,

Shares subject to forward sale agreement | 2.0 |  |  | — |  |  | 2.0 |  |  | — |

The Company may settle portions of its Affiliate equity purchases in shares of its common stock. Because it is the Company’s intent to settle these potential purchases in cash, the calculation of diluted earnings per share excludes any potential dilutive effect from possible share settlements of Affiliate equity purchases.
In the three and nine months ended September 30, 2017, the Company repurchased 0.4 million and 1.7 million shares, respectively, at an average price per share of $175.68 and $164.00, respectively.

17. | Segment Information

In the first quarter of 2017, the Company’s Chief Operating Decision Maker (the “CODM”) changed the manner in which he assesses the Company’s performance. In 2016, the CODM assessed the performance of the Company in three business segments representing three distribution channels. Given an increase in the number of the Company’s Affiliates accounted for under the equity method of accounting and changes in the way asset management services are delivered, during the first quarter of 2017, the CODM began to assess the performance of the Company as a single global active asset management company. As a result, the CODM now reviews information organized around one operating segment to evaluate and manage the Company’s business operations. Therefore, the Company has determined that it has one reportable segment. In connection with this change, the Company completed impairment assessments based on its former three distribution channels, as well as its single global active asset management reporting unit, and determined that there were no impairments under either approach.

Item 2. | Management’s Discussion and Analysis of Financial Condition and Results of Operations

Forward-Looking Statements
Certain matters discussed in this Quarterly Report on Form 10-Q, in our other filings with the Securities and Exchange Commission, in our press releases and in oral statements made with the approval of an executive officer may constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These statements include, but are not limited to, statements related to our expectations regarding the performance of our business, our financial results, our liquidity and capital resources and other non-historical statements, and may be prefaced with words such as “outlook,” “guidance,” “believes,” “expects,” “potential,” “continues,” “may,” “will,” “should,” “seeks,” “approximately,” “predicts,” “projects,” “intends,” “plans,” “estimates,” “pending investments,” “anticipates” or the negative version of these words or other comparable words. Such statements are subject to certain risks and uncertainties, including, among others, the factors discussed under the caption “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2016.
These factors (among others) could affect our financial performance and cause actual results to differ materially from historical earnings and those presently anticipated and projected. Forward-looking statements speak only as of the date they are made, and we will not undertake and we specifically disclaim any obligation to release publicly the result of any revisions that may be made to any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of events, whether or not anticipated. In that respect, we caution readers not to place undue reliance on any such forward-looking statements.
Management’s Discussion and Analysis should be read in conjunction with the Consolidated Financial Statements and the notes thereto contained elsewhere in this Quarterly Report on Form 10-Q.
Executive Overview
We are a global asset management company with equity investments in leading boutique investment management firms, which we refer to as our “Affiliates.” Our innovative partnership approach allows each Affiliate’s management team to own significant equity in their firm and maintain operational autonomy. Our strategy is to generate shareholder value through the growth of existing Affiliates, as well as through investments in new Affiliates and additional investments in existing Affiliates. In addition, we provide centralized assistance to our Affiliates in strategic matters, marketing, distribution, product development and operations. As of September 30, 2017, our aggregate assets under management were $803.7 billion, in more than 550 investment products across a broad range of active, return-oriented strategies.
We hold meaningful equity interests in each of our Affiliates. In certain cases, we consolidate the Affiliate’s financial results in our Revenue, Operating expenses and Non-operating (income) and expenses. In other cases, we use the equity method of accounting and our share of the Affiliate’s financial results is reported (net of intangible amortization) in Income from equity method investments. While we account for a majority of our Affiliates on a consolidated basis of accounting, a growing number of our Affiliates are accounted for on an equity method basis and are integral to our operations. Accordingly, Income from equity method investments is included in Operating income.
Whether we account for an Affiliate on a consolidated or equity method basis of accounting, we generally maintain the same partnership approach and provide support and assistance in substantially the same manner, and our operating model is generally the same. Furthermore, our Affiliates are impacted by similar marketplace factors and operational trends, which may not be observable when analyzing the financial results of our consolidated and equity method Affiliates separately. Therefore, we believe our aggregate operating measures of assets under management, average assets under management and aggregate revenue, which incorporate the assets under management and revenues of all of our Affiliates, regardless of the accounting treatment, have become increasingly important in providing management and investors with a more comprehensive view of the operating performance and material trends across our entire business. Aggregate revenue is calculated by combining the Revenue of our consolidated Affiliates with equity method revenue. We discuss both Revenue at our consolidated Affiliates and equity method revenue in our Results of Operations. Equity method revenue and aggregate revenue are provided in addition to, but not as substitutes for, Revenue at our consolidated Affiliates.
The following table presents our key operating performance measures:

(1) | Assets under management is presented on a current basis without regard to the timing of the inclusion of an Affiliate’s financial results in our Consolidated Financial Statements. Average assets under management provides a more meaningful relationship to our financial and operating results as it reflects both the particular billing patterns of Affiliate sponsored products and client accounts and corresponds with the timing of the inclusion of an Affiliate's financial results in our Consolidated Financial Statements.

(2) | Equity method revenue consists of asset based revenue and performance fees earned by our equity method Affiliates.

Assets Under Management
Through our Affiliates, we manage active return-oriented strategies rather than passive or indexing strategies, fixed income or money market products, which typically carry lower fee rates. We continue to see meaningful client demand for active return-oriented strategies, particularly in alternative and multi-asset strategies, reflecting continued investor demand for returns that are less correlated to traditional equity and fixed income markets. Investor demand for passively managed and indexing strategies has continued, particularly for the large cap U.S. equity portion of client portfolios, and we have experienced outflows in U.S. equity strategies consistent with this industry-wide trend. We expect client demand for alternative and multi-asset strategies to continue, and believe the best-performing active equity managers (whether global-, regional- or country-specific) will continue to have significant opportunities to grow from net client cash inflows. We believe we are well positioned to benefit from these trends.
The following charts and tables provide information regarding the composition of and changes in our assets under management on a current basis by active return-oriented strategy and client type:

(1) | Alternatives primarily include assets under management in long and short public equity, control equity, managed futures, multi-strategy, and other alternative and hedge fund strategies, as well as energy and infrastructure investments and primary and secondary private equity strategies. Alternative strategies generate earnings from (i) management fees from products subject to lock-ups or similar restrictions, (ii) management fees from products not subject to such restrictions and/or (iii) performance fees and carried interest.

(2) | Global equities include emerging markets strategies, which accounted for 10% of our aggregate assets under management as of September 30, 2017.

_________________________

(1) | Foreign exchange reflects the impact of translating non-U.S. dollar denominated assets under management into U.S. dollars for reporting purposes.

In addition to assets under management, we also report average assets under management. Average assets under management provides a more meaningful relationship to our financial and operating results as it reflects both the particular billing patterns of Affiliate sponsored products and client accounts and corresponds with the timing of the inclusion of an Affiliate’s financial results in our Consolidated Financial Statements.
Average assets under management increased $127.1 billion or 19% in the three months ended September 30, 2017 compared to the corresponding period in the prior year, due to a 32% increase in average assets under management at equity method Affiliates and a 10% increase in average assets under management at consolidated Affiliates. Average assets under management increased $121.0 billion or 19% in the nine months ended September 30, 2017 compared to the corresponding period in the prior year, due to a 34% increase in average assets under management at equity method Affiliates and a 8% increase in average assets under management at consolidated Affiliates.
Aggregate Revenue
Aggregate revenue is calculated by combining the Revenue of our consolidated Affiliates with equity method revenue. Aggregate revenue and equity method revenue are provided in addition to, but not as substitutes for, Revenue at our consolidated Affiliates. We derive our aggregate revenue primarily from asset based revenue and performance fees from investment management services. Asset based revenue includes advisory and other fees earned by our Affiliates for services provided to their clients and are typically determined as a percentage of the value of a client’s assets under management. Performance fees are billed based upon investment performance, typically on an absolute basis or relative to a benchmark.
Our ratio of asset based revenue to average assets under management (“asset based revenue ratio”), either in the aggregate or separately for consolidated Affiliates or equity method Affiliates, is calculated as asset based revenue divided by average assets under management for the respective Affiliates. Our asset based revenue ratios may change as a result of new investments, client cash flows, market changes, foreign exchange or changes in contractual fees.
The following table presents the Revenue of our consolidated Affiliates and equity method revenue, and when combined, aggregate revenue:

|  | For the Three Months Ended September 30, |  |  |  | For the Nine Months Ended September 30, |  |
(in millions) |  | 2016 |  | 2017 |  | % Change |  | 2016 |  | 2017 |  | % Change
Revenue |  | $ | 544.7 |  |  | $ | 585.7 |  |  | 8 | % |  | $ | 1,644.2 |  |  | $ | 1,700.9 |  |  | 3 | %
Equity method revenue |  | 456.4 |  |  | 686.6 |  |  | 50 | % |  | 1,350.5 |  |  | 2,159.8 |  |  | 60 | %

Aggregate revenue increased 27% in the three months ended September 30, 2017. This increase was due to a $230.2 million or 50% increase in equity method revenue and a $41.0 million or 8% increase in Revenue at our consolidated Affiliates. The increase in equity method revenue was due to an increase of $166.8 million or 36% from asset based revenue and an
25

increase of $63.4 million or 14% from performance fees. The increase in Revenue at our consolidated Affiliates was due to an increase of $38.2 million or 7% from asset based revenue and a $2.8 million or 1% increase from performance fees.
Aggregate revenue increased 29% in the nine months ended September 30, 2017, due to an increase in equity method revenue of $809.3 million or 60% and a $56.7 million or 3% increase in Revenue at our consolidated Affiliates. The increase in equity method revenue was due to an increase of $532.9 million or 40% from asset based revenue and an increase of $276.4 million or 20% from performance fees. The increase in Revenue at our consolidated Affiliates was due to a $70.1 million or 4% increase from asset based revenue, partially offset by a $13.4 million or 1% decrease from performance fees.
See Results of Operations for a further discussion of the changes in Revenue at our consolidated Affiliates and equity method revenue.
Financial and Supplemental Financial Performance Measures
The following table presents our key financial and supplemental financial performance measures:

|  | For the Three Months Ended September 30, |  |  |  | For the Nine Months Ended September 30, |  |
(in millions) |  | 2016 |  | 2017 |  | % Change |  | 2016 |  | 2017 |  | % Change
Net income (controlling interest) |  | $ | 110.2 |  |  | $ | 125.4 |  |  | 14 | % |  | $ | 322.5 |  |  | $ | 374.2 |  |  | 16 | %
Adjusted EBITDA (controlling interest)(1) |  | 219.8 |  |  | 256.3 |  |  | 17 | % |  | 655.8 |  |  | 754.8 |  |  | 15 | %
Economic net income (controlling interest)(1) |  | 165.5 |  |  | 191.3 |  |  | 16 | % |  | 492.3 |  |  | 563.2 |  |  | 14 | %

__________________________

(1) | Adjusted EBITDA (controlling interest) and Economic net income (controlling interest) are non-GAAP performance measures and are discussed in “Supplemental Financial Performance Measures.”

We believe Adjusted EBITDA (controlling interest) is an important supplemental financial performance measure for our management and investors. Adjusted EBITDA (controlling interest) provides a comprehensive view of our share of the financial performance of our entire business before interest, taxes, depreciation, amortization, impairments and adjustments to our contingent payment obligations. Conversely, our GAAP financial performance measures, Operating income and Income before income taxes, include the non-controlling interest’s share of financial performance.
Our ownership level of consolidated Affiliates is higher than our ownership level of our equity method Affiliates and, as a result, we experience a greater proportion of an increase or decrease in Revenue from our consolidated Affiliates than an increase or decrease in our equity method revenue. While our equity method revenue increased 50% in the three months ended September 30, 2017, our Revenue from consolidated Affiliates increased 8%, resulting in a $36.5 million or 17% increase in Adjusted EBITDA (controlling interest). In the nine months ended September 30, 2017, our equity method revenue increased 60%, while our Revenue from consolidated Affiliates increased 3%, resulting in a $99.0 million or 15% increase in Adjusted EBITDA (controlling interest).
Our Net income (controlling interest) increased $15.2 million or 14% and $51.7 million or 16% in the three and nine months ended September 30, 2017, respectively, which was consistent with the 17% and 15% increases in Adjusted EBITDA (controlling interest) during the respective periods.
We consider Economic net income (controlling interest) to be an important measure of our financial performance, as we believe it best represents our performance after tax and before our share of non-cash expenses relating to our acquisition of interests in our Affiliates. Our Economic net income (controlling interest) increased $25.8 million or 16% and $70.9 million or 14% in the three and nine months ended September 30, 2017, respectively, which was consistent with the 17% and 15% increases in Adjusted EBITDA (controlling interest) during the respective periods.
Results of Operations
The following discussion includes the financial results of our consolidated and equity method Affiliates. Our consolidated Affiliates’ financial results are included in our Revenue, Operating expenses and Non-operating (income) and expenses, and our share of our equity method Affiliates’ financial results is reported (net of intangible amortization) in Income from equity method investments in Operating income.
Revenue
26

The following table summarizes our consolidated Affiliate average assets under management and Revenue:

| For the Three Months Ended September 30, |  |  |  | For the Nine Months Ended September 30, |  |
(in millions, except as noted) | 2016 |  | 2017 |  | % Change |  | 2016 |  | 2017 |  | % Change
Consolidated Affiliates average assets under management (in billions) | $ | 378.0 |  |  | $ | 414.5 |  |  | 10 | % |  | $ | 371.9 |  |  | $ | 400.9 |  |  | 8 | %
Revenue | $ | 544.7 |  |  | $ | 585.7 |  |  | 8 | % |  | $ | 1,644.2 |  |  | $ | 1,700.9 |  |  | 3 | %

Our Revenue increased $41.0 million or 8% in the three months ended September 30, 2017, due to a $38.2 million or 7% increase from asset based revenue, and a $2.8 million or 1% increase from performance fees. The change in asset based revenue was due to a 10% increase in average assets under management, partially offset by a 2% decline in our asset based revenue ratio. The decline in our asset based revenue ratio was primarily due to changes in the composition of our average assets under management.
Our Revenue increased $56.7 million or 3% in the nine months ended September 30, 2017, due to a $70.1 million or 4% increase from asset based revenue, partially offset by a $13.4 million or 1% decrease from performance fees. The change in asset based revenue was due to an 8% increase in average assets under management and a 3% decline in our asset based revenue ratio. The decline in our asset based revenue ratio was due to a decrease in asset based revenue related to renewal commissions at one of our Affiliates in the United Kingdom as a result of a regulatory change which was offset by a reduction in distribution expenses at the Affiliate which were reported in Selling, general and administrative expenses. The decline in our asset based revenue ratio was also due to changes in the composition of our average assets under management.
Operating Expenses
The following table summarizes our consolidated operating expenses:

| For the Three Months Ended September 30, |  |  |  | For the Nine Months Ended September 30, |  |
| % Change |  | % Change
(in millions) | 2016 |  | 2017 |  |  | 2016 |  | 2017 |
Compensation and related expenses | $ | 244.2 |  |  | $ | 238.7 |  |  | (2 | )% |  | $ | 702.9 |  |  | $ | 722.9 |  |  | 3%
Selling, general and administrative | 94.2 |  |  | 91.9 |  |  | (2 | )% |  | 286.7 |  |  | 269.7 |  |  | (6)%
Intangible amortization and impairments | 26.9 |  |  | 21.2 |  |  | (21 | )% |  | 82.2 |  |  | 65.1 |  |  | (21)%
Depreciation and other amortization | 5.0 |  |  | 4.8 |  |  | (4 | )% |  | 15.0 |  |  | 14.9 |  |  | (1)%
Other operating expenses (net) | 3.4 |  |  | 10.3 |  |  | N.M.(1) |  |  | 25.9 |  |  | 32.0 |  |  | 24%
Total operating expenses | $ | 373.7 |  |  | $ | 366.9 |  |  | (2 | )% |  | $ | 1,112.7 |  |  | $ | 1,104.6 |  |  | (1)%

___________________________

(1) | Percentage change is not meaningful.

Our operating expenses are primarily attributable to the non-controlling interests because the substantial majority of these expenses are incurred by consolidated Affiliates with which we share in revenue without regard to expenses. For these Affiliates, the amount of their operating expenses, including compensation, is generally determined by the percentage of revenue allocated to operating expenses as part of the structured partnership interests in place at the respective Affiliate. Accordingly, our operating expenses are impacted by increases or decreases in a consolidated Affiliate’s revenue and corresponding increases or decreases in a consolidated Affiliate’s operating expenses.
Compensation and related expenses decreased $5.5 million or 2% in the three months ended September 30, 2017, primarily due to a $11.9 million or 5% decrease from compensation expenses associated with Affiliate equity transactions, partially offset by an $8.0 million or 3% increase from compensation expenses at Affiliates. These changes primarily relate to the non-controlling interests.
Compensation and related expenses increased $20.0 million or 3% in the nine months ended September 30, 2017, primarily due to a $17.0 million or 2% increase from compensation expenses at Affiliates and a $3.6 million or 1% increase from compensation expenses associated with Affiliate equity transactions. These changes primarily relate to the non-controlling interests.
27

There was no significant change in Selling, general and administrative expenses in the three months ended September 30, 2017. Selling, general and administrative expenses decreased $17.0 million or 6% in the nine months ended September 30, 2017, primarily due to a $8.8 million or 3% decrease from a reduction in distribution expenses, related to commissions at certain of our Affiliates in the United Kingdom and a $5.8 million or 2% decrease from a reduction of expenses in wealth management initiatives.
Intangible amortization and impairments decreased $5.7 million or 21% in the three months ended September 30, 2017, due to a $3.3 million or 12% decrease from a change in the pattern of economic benefit for certain assets and a $2.4 million or 9% decrease from certain assets being fully amortized.
Intangible amortization and impairments decreased $17.1 million or 21% in the nine months ended September 30, 2017, due to a $11.6 million or 14% decrease from a change in the pattern of economic benefit for certain assets and a $5.5 million or 7% decrease from certain assets being fully amortized.
There were no significant changes in Depreciation and other amortization in the three and nine months ended September 30, 2017.
Other operating expenses (net) increased $6.9 million in the three months ended September 30, 2017, primarily from decreases in net gains on Affiliate sponsored consolidated investment products of $6.2 million. This change primarily relates to the non-controlling interests.
Other operating expenses (net) increased $6.1 million or 24% in the nine months ended September 30, 2017, primarily from decreases in net gains on Affiliate sponsored consolidated investment products of $4.8 million or 19%. This change primarily relates to the non-controlling interests.
Income from Equity Method Investments
For equity method Affiliates, our share of an Affiliate’s earnings or losses is contractually calculated using a formula, which is based either on a fixed percentage of such Affiliate’s revenue without regard to expenses or by reference to such Affiliate’s revenue less certain agreed-upon expenses. Our share of an equity method Affiliate’s earnings or losses is reported (net of intangible amortization attributable to our investment in an Affiliate) in Income from equity method investments in Operating income.
Additional investments in existing or new Affiliates will generally impact our financial results in the year of investment and, depending upon the timing, in the following year when the full-year financial results of the Affiliate investment are reflected in our Consolidated Financial Statements.
The following table summarizes equity method earnings and equity method intangible amortization, which together comprise Income from equity method investments, as well as equity method Affiliate average assets under management and equity method revenue. Equity method revenue is provided in addition to, but not as a substitute for, Revenue at our consolidated Affiliates.

| For the Three Months Ended September 30, |  |  |  | For the Nine Months Ended September 30, |  |
(in millions, except as noted) | 2016 |  | 2017 |  | % Change |  | 2016 |  | 2017 |  | % Change

Our equity method revenue increased $230.2 million or 50% in the three months ended September 30 2017, due to a $166.8 million or 36% increase from asset based revenue and a $63.4 million or 14% increase from performance fees. The increase in asset based revenue was due to increases of $125.4 million or 27% from our 2016 investments in new Affiliates and $41.4 million or 9% from existing Affiliates. The increase in performance fees was due to a $57.8 million or 13% increase from existing Affiliates and a $5.6 million or 1% increase from our 2016 investments in new Affiliates.
28

While equity method revenue increased 50% in the three months ended September 30, 2017, equity method earnings increased $15.1 million or 19%, primarily due to our 2016 investments in new Affiliates, in which we own less of the equity interests than in our existing equity method Affiliates.
Equity method intangible amortization increased $11.9 million or 85% in the three months ended September 30, 2017, due to our 2016 investments in new Affiliates.
Our equity method revenue increased $809.3 million or 60% in the nine months ended September 30, 2017, due to a $532.9 million or 40% increase from asset based revenue and a $276.4 million or 20% increase from performance fees. The increase in asset based revenue was due to increases of $395.4 million or 29% from our 2016 investments in new Affiliates and $137.5 million or 10% from existing Affiliates. The increase in performance fees was due to a $238.2 million or 18% increase from performance fees from our 2016 investments in new Affiliates and a $38.1 million or 3% increase from existing Affiliates.
While equity method revenue increased 60% in the nine months ended September 30, 2017, equity method earnings increased $59.6 million or 24%, primarily due to our 2016 investments in new Affiliates, in which we own less of the equity interests than in our existing equity method Affiliates.
Equity method intangible amortization increased $28.7 million or 67% in the nine months ended September 30, 2017, due to a $22.9 million or 53% increase from our 2016 investments in new Affiliates and a $5.8 million or 14% increase from a change in the pattern of economic benefit related to assets at certain existing Affiliates.
Non-Operating (Income) and Expenses
The following table summarizes non-operating income and expense data:

| For the Three Months Ended September 30, |  |  |  | For the Nine Months Ended September 30, |  |
(in millions) | 2016 |  | 2017 |  | % Change |  | 2016 |  | 2017 |  | % Change
Investment and other income | $ | (11.0 | ) |  | $ | (15.6 | ) |  | 42 | % |  | $ | (26.7 | ) |  | $ | (44.7 | ) |  | 67 | %

Income taxes | 50.3 |  |  | 66.1 |  |  | 31 | % |  | 159.7 |  |  | 188.2 |  |  | 18 | %

___________________________

(1) | Percentage change is not meaningful.

Investment and other income increased $4.6 million or 42% in the three months ended September 30, 2017, primarily due to a $2.9 million or 26% increase from changes in the fair value of investments and a $1.4 million or 13% increase from realized gains on the sale of investment securities.
Investment and other income increased $18.0 million or 67% in the nine months ended September 30, 2017, primarily due to a $14.2 million or 53% increase from changes in the fair value of investments and a $5.7 million or 21% increase from realized gains on the sale of investment securities, partially offset by a $1.7 million or 6% decrease from lower dividend income.
There were no significant changes in Interest expense in the three and nine months ended September 30, 2017.
There was no significant change in Imputed interest expense and contingent payment arrangements in the three months ended September 30, 2017. Imputed interest and contingent payment arrangements increased $3.9 million in the nine months ended September 30, 2017, primarily due to a $2.8 million gain on the revaluation of a contingent payment arrangement in the nine months ended September 30, 2016, which did not recur, and a $1.4 million expense on the revaluation of a contingent payment arrangement in the nine months ended September 30, 2017.
Income taxes increased $15.8 million or 31% and $28.5 million or 18% in the three and nine months ended September 30, 2017, respectively, primarily due to an increase in Income before income taxes attributable to the controlling interest, partially offset by stock compensation tax benefits. In the three months ended September 30, 2016, we also recognized a benefit due to the reduction in corporate tax rates in the United Kingdom, which did not recur in 2017.
Net Income
29

The previously discussed changes in Revenue, expenses and Income from equity method investments had the following effect on Net income:

| For the Three Months Ended September 30, |  |  |  | For the Nine Months Ended September 30, |  |
(in millions) | 2016 |  | 2017 |  | % Change |  | 2016 |  | 2017 |  | % Change

Supplemental Financial Performance Measures
Adjusted EBITDA (controlling interest)
As supplemental information, we provide a non-GAAP measure that we refer to as Adjusted EBITDA (controlling interest). Adjusted EBITDA (controlling interest) represents our earnings before our share of interest expense, income taxes, depreciation, amortization, impairments and adjustments to our contingent payment obligations. We believe that many investors use this information when assessing the financial performance of companies in the investment management industry. This non-GAAP measure is provided in addition to, but not as a substitute for, Net income (controlling interest) or any other GAAP measures of financial performance.
The following table provides a reconciliation of Net income (controlling interest) to Adjusted EBITDA (controlling interest):

| For the Three Months Ended September 30, |  | For the Nine Months Ended September 30,

(1) | For the nine months ended September 30, 2016 and 2017, Imputed interest expense and contingent payment arrangements include gains from adjustments to our contingent payment obligations of $2.8 million ($1.7 million net of tax) and expenses from adjustments to our contingent payment obligations of $1.4 million ($0.9 million net of tax), respectively. There were no contingent payment adjustments in the three months ended September 30, 2016 and 2017.

(2) | Our reported intangible amortization includes amortization attributable to our non-controlling interests. For our equity method Affiliates, we do not separately report intangible amortization in our Consolidated Statements of Income. Our share of these Affiliates’ amortization is reported in Income from equity method investments.

The following table summarizes the Intangible amortization and impairments shown above:

Economic Net Income (controlling interest) and Economic Earnings Per Share
As supplemental information, we also provide non-GAAP measures that we refer to as Economic net income (controlling interest) and Economic earnings per share. We consider Economic net income (controlling interest) and Economic earnings per share to be important measures of our financial performance, as we believe they best represent our performance before our share of non-cash expenses relating to our acquisition of interests in our Affiliates, and they are, therefore, employed as our principal financial performance measures. Economic net income (controlling interest) and Economic earnings per share are used by our management and Board of Directors as our principal performance benchmarks, including as one of the measures for aligning executive compensation with stockholder value. These measures are provided in addition to, but not as substitutes for, other GAAP measures of financial performance, such as Net income (controlling interest) and Earnings per share (diluted).
Under our Economic net income (controlling interest) definition, we add to Net income (controlling interest) our share of pre-tax intangible amortization and impairments (including the portion attributable to equity method Affiliates), deferred taxes related to intangible assets, and other economic items, which include non-cash imputed interest (principally related to the accounting for convertible securities and contingent payment arrangements) and certain Affiliate equity expenses. We add back intangible amortization and impairments attributable to acquired client relationships because these expenses do not correspond to the changes in value of these assets, which do not diminish predictably over time. The portion of deferred taxes generally attributable to intangible assets (including goodwill) is added back because we believe it is unlikely these accruals will be used to settle material tax obligations. We add back non-cash imputed interest and reductions or increases in contingent payment arrangements to better reflect our contractual interest obligations. We add back non-cash expenses relating to certain transfers of equity between Affiliate partners when these transfers have no dilutive effect to shareholders.
Economic earnings per share represents Economic net income (controlling interest) divided by the Average shares outstanding (adjusted diluted). In this calculation, the potential share issuance in connection with our convertible securities is measured using a “treasury stock” method. Under this method, only the net number of shares of common stock equal to the value of these convertible securities in excess of par, if any, is deemed to be outstanding. We believe the inclusion of net shares under a treasury stock method best reflects the benefit of the increase in available capital resources (which could be used to repurchase shares of common stock) that occurs when these securities are converted and we are relieved of our debt obligation. This method does not take into account any increase or decrease in our cost of capital in an assumed conversion.
The following table provides a reconciliation of Net income (controlling interest) to Economic net income (controlling interest):

(3) | For the three months ended September 30, 2016 and 2017, Other economic items were net of income tax expense of $0.1 million and $0.3 million, respectively. For the nine months ended September 30, 2016 and 2017, Other economic items were net of an income tax benefit of $0.1 million and income tax expense of $1.4 million, respectively.

Liquidity and Capital Resources
During the nine months ended September 30, 2017, we met our cash requirements primarily through cash generated by operating activities. Our principal uses of cash during the quarter were, and for the foreseeable future are expected to be, for
31

repayments of senior debt, distributions to Affiliate equity holders, repurchases of common stock, Affiliate equity repurchases, the payment of cash dividends on our common stock, and general working capital purposes. We also expect that a principal use of cash will be for investments in new and existing Affiliates. We anticipate that cash flows from operations, together with borrowings under our revolver and proceeds from our equity distribution program, will be sufficient to support our cash flow needs for the foreseeable future.
Cash and cash equivalents at December 31, 2016 and September 30, 2017 were $430.8 million and $374.7 million, respectively, including $18.9 million and $24.9 million, respectively, in our wholly-owned foreign subsidiaries, which could be repatriated without accruing or paying any significant additional U.S. taxes.
The following table summarizes our cash flow activities:

| For the Nine Months Ended September 30,
(in millions) | 2016 |  | 2017
Operating cash flow | $ | 684.5 |  |  | $ | 800.5 |
Investing cash flow | (868.7 | ) |  | 4.9 |
Financing cash flow | 36.6 |  |  | (871.5 | )

Operating Cash Flow
In the nine months ended September 30, 2017, Cash flow from operating activities increased $116.0 million, of which approximately 70% was attributable to the controlling interest. Cash flow from operating activities attributable to the controlling interest increased primarily from the receipt of cash distributions of our share of equity method earnings from our 2016 investments in new Affiliates.
Investing Cash Flow
In the nine months ended September 30, 2017, Cash flows from investing activities, which is primarily attributable to the controlling interest, increased $873.6 million, primarily due to a decrease in Investments in Affiliates of $854.6 million.
Financing Cash Flow
In the nine months ended September 30, 2017, Cash flows used in financing activities, which is primarily attributable to the controlling interest, increased $908.1 million. This increase was primarily due to a change in senior debt activity from net borrowings of $230.0 million in the nine months ended September 30, 2016 to net repayments of $200.0 million in the nine months ended September 30, 2017. This increase was also due to an increase in repurchases of common stock of $243.0 million and a decrease in cash received for the issuance of common stock of $129.5 million.
The following table summarizes the carrying value of our outstanding indebtedness:

(in millions) | December 31, 2016 |  | September 30, 2017
Senior bank debt | $ | 870.0 |  |  | $ | 870.0 |
Senior notes | 945.1 |  |  | 745.5 |
Convertible securities | 307.5 |  |  | 309.3 |

Senior Bank Debt and Senior Notes
We have a $1.45 billion senior unsecured multicurrency revolving credit facility (the “revolver”) and a $385.0 million senior unsecured term loan facility (the “term loan” and, together with the revolver, the “credit facilities”). The credit facilities both mature on September 30, 2020.
The credit facilities contain financial covenants with respect to leverage and interest coverage, as well as customary affirmative and negative covenants, including limitations on priority indebtedness, asset dispositions and fundamental corporate changes, and certain customary events of default. As of September 30, 2017, we were in compliance with all terms of our credit facilities and had approximately $1 billion of remaining capacity under our revolver, all of which we could borrow and remain in compliance with our credit facilities.
32

In the three months ended September 30, 2017, we redeemed all $200.0 million principal amount outstanding of our 6.375% senior unsecured notes due 2042 at a redemption price equal to 100% of the principal amount. The notes were subsequently canceled and retired.
We are currently rated A3 by Moody’s Investors Service and A- by S&P Global Ratings. A downgrade of our credit rating, including a downgrade to below investment grade, would not trigger a default or have any other significant impact on the terms of our existing credit facilities. A reduction in our credit rating could, however, increase our borrowing costs. Additionally, a downgrade of our credit rating below investment grade in connection with a change in control would require us to make a repurchase offer on our senior notes.
Equity Distribution Program
In 2016, we entered into equity distribution and forward equity agreements with several major securities firms under which we, from time to time, may issue and sell shares of our common stock (immediately or on a forward basis) having an aggregate sales price of up to $500.0 million (the “equity distribution program”). As of September 30, 2017, no sales have occurred under the equity distribution program.
Affiliate Equity
Many of our Affiliate agreements provide us with a conditional right to call and Affiliate equity holders with the conditional right to put their Affiliate equity interests to us at certain intervals. For equity method Affiliates, we do not typically have such put and call arrangements. The purchase price of these conditional purchases is generally calculated based upon a multiple of the Affiliate’s cash flow distributions, which is intended to represent fair value. Affiliate equity holders are also permitted to sell their equity interests to other individuals or entities in certain cases, subject to our approval or other restrictions.
As of September 30, 2017, our current redemption value of $804.6 million for these interests has been presented as Redeemable non-controlling interests. Although the timing and amounts of these purchases are difficult to predict, we repurchased $161.5 million of Affiliate equity during the nine months ended September 30, 2017, and expect to repurchase approximately $10 million in the fourth quarter of 2017. In the event of a repurchase, we become the owner of the cash flow associated with the repurchased equity.
Commitments
We have committed to co-invest in certain investment partnerships. As of September 30, 2017, these unfunded commitments totaled $94.9 million and may be called in future periods.
As of September 30, 2017, we were contingently liable, upon achievement by certain Affiliates of specified financial targets, to make payments related to our investments in Affiliates through 2019. For our consolidated Affiliates, we were contingently liable for up to $21.7 million, and expected to make payments of $8.9 million ($1.6 million in 2017). The present value of these expected payments was $8.1 million. For our equity method Affiliates, we were contingently liable for up to $170.0 million, and expected to make no payments.
Affiliate equity interests provide holders with a conditional right to put their interests to us over time. In addition, in connection with an investment in an Affiliate accounted for under the equity method, we entered into an arrangement with a minority owner of the Affiliate that gives such owner the right to sell a portion of its ownership interest in the Affiliate to us annually beginning in the fourth quarter of 2018. The purchase price of these conditional purchases will be at fair market value on the date of the transaction.
We and certain of our Affiliates operate under regulatory authorities, which require that we and they maintain minimum financial or capital requirements.
Share Repurchases
Our Board of Directors authorized share repurchase programs in May 2015 and January 2017, authorizing us to repurchase up to 3.0 million and 1.9 million shares of our common stock, respectively, for a total of 4.9 million shares, which do not expire. As of September 30, 2017, we had repurchased 2.6 million shares of this total authorized amount. In the three and nine months ended September 30, 2017, we repurchased 0.4 million and 1.7 million shares, respectively, at an average price per share of $175.68 and $164.00, respectively.

Item 3. | Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes to our Quantitative and Qualitative Disclosures About Market Risk in the three months ended September 30, 2017. Please refer to the below as well as the additional disclosures in Item 7A of our 2016 Annual Report on Form 10-K.
Foreign Currency Exchange Risk
To illustrate the effect of possible changes in currency exchange rates, we estimate a 1% change in the pound sterling and Canadian dollar to U.S. dollar exchange rates would have resulted in changes to stockholders’ equity of approximately $13 million and $2 million, respectively, as of September 30, 2017, and annual changes to Income before income taxes of $1.1 million and $0.3 million, respectively.

Item 4. | Controls and Procedures

We carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures during the quarter covered by this Quarterly Report on Form 10-Q. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the quarter covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures are effective in ensuring that (i) the information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and (ii) such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, we recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management
34

necessarily was required to apply its judgment in evaluating and implementing possible controls and procedures. Our disclosure controls and procedures were designed to provide reasonable assurance of achieving their stated objectives, and our principal executive officer and principal financial officers concluded that our disclosure controls and procedures were effective at the reasonable assurance level. We review on an ongoing basis and document our disclosure controls and procedures, and our internal control over financial reporting, and we may from time to time make changes in an effort to enhance their effectiveness and ensure that our systems evolve with our business.
No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the quarter covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
