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 statement of the Company’s interim financial position and results of operations have been included and all intercompany balances and transactions have been eliminated. In the first quarter of 2018, the Company changed its Consolidated Financial Statement presentation to present non-classified Consolidated Statements of Income and Consolidated Condensed Balance Sheets. These changes, along with other reclassifications, have 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, 2017 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. | Accounting Standards and Policies

Recently Adopted Accounting Standards
The Company adopted several new Accounting Standard Updates (“ASUs”) in the nine months ended September 30, 2018. While none of these ASUs had a significant impact on the Company’s Consolidated Financial Statements, the Company was required to update certain of its significant accounting policies. For a complete list of significant accounting policies, see the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017.
Revenue Recognition
On January 1, 2018, the Company adopted ASU 2014-09, Revenue from Contracts with Customers (as amended), using a modified retrospective method and, as a result, updated its revenue recognition accounting policy as follows.
Revenue primarily represents asset and performance based fees earned by the Company and its Affiliates for managing the assets of clients. Substantially all of the Company’s and its Affiliates’ contracts contain a single performance obligation, which is the provision of investment management services. Investment management services are performed and consumed simultaneously and, therefore, the Company recognizes asset based fees ratably over time. Broker-dealer and administrative fees for services that are provided and consumed over time, and which are related to Affiliate sponsored investment products, are also included ratably in revenue. Revenue recognized by the Company is adjusted for any expense reimbursement arrangements.
Performance based fees, including carried interests, are recognized only upon the satisfaction of performance obligations, the resolution of any constraints (which may extend over one or more reporting periods) and when it is improbable that there will be a significant reversal in the amount of revenue recognized. As a result, any performance based fees or carried interest recognized in the current reporting period may relate to performance obligations satisfied in a previous reporting period.
Revenue from investment management, broker-dealer and administrative services is typically based on the value of client assets over time, which is typically determined using observable market data. Services may be invoiced in advance or in arrears and are payable upon receipt. Any fees collected in advance are deferred and recognized as the services are performed and consumed.
The Company and its Affiliates have contractual arrangements with third parties to provide distribution-related services. Fees received and expenses incurred under these arrangements are primarily based on the value of client assets over time.
8

AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
Distribution-related fees are presented in revenue gross of any related expenses when the Company and its Affiliates are the principal in its role as primary obligor under their distribution-related services arrangements. Distribution-related expenses are presented within Selling, general and administrative expenses in the Consolidated Statements of Income.
The Company and its Affiliates may enter into contracts for which the costs to obtain or fulfill the contract are based upon a percentage of the value of a client’s future assets under management. The Company records these variable costs when incurred because they are subject to market volatility and are not estimable upon the inception of a contract with a client. Any expenses paid in advance are capitalized and amortized on a systematic basis, consistent with the transfer of services, which is the equivalent of recognizing the costs as incurred.
Investments in Marketable Securities
On January 1, 2018, the Company also adopted ASU 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities, using a modified retrospective method and, as a result, updated its investments in marketable securities accounting policy as follows.
Upon the adoption of ASU 2016-01, the Company no longer classifies these securities as either trading or available-for-sale securities. Realized and unrealized gains or losses on investments in marketable securities are reported within Investment and other income in the Consolidated Statements of Income. Realized gains and losses are recorded on the trade date on a specific identified basis.
Derivative Financial Instruments
On July 1, 2018, the Company early adopted ASU 2017-12, Derivatives and Hedging, using a modified retrospective method and, as a result, updated its derivative financial instruments accounting policy as follows.
The Company and its Affiliates may utilize derivative financial instruments to offset exposure to changes in interest rates, foreign currency exchange rates and markets. The Company records derivatives in the Consolidated Condensed Balance Sheets at fair value. If the Company’s or its Affiliates’ derivative financial instruments do not qualify as cash flow, net investment or fair value hedges, changes in the fair value of the derivatives are recognized as a gain or loss in Investment and other income in the Consolidated Statements of Income.
If the Company’s or its Affiliates’ derivative financial instruments qualify as cash flow or net investment hedges, the effective portion of the unrealized gain or loss is recorded in Other comprehensive income (loss) as a separate component of stockholders’ equity and reclassified to earnings with the hedged item. For cash flow hedges, hedge effectiveness is generally measured by comparing the present value of the cumulative change in the expected future cash flows of the hedged contract with the present value of the cumulative change in the expected future cash flows of the hedged item. For net investment hedges, hedge effectiveness is measured using the spot rate method. For fair value hedges, the entire change in the fair value of the hedging instrument is presented in earnings with the hedged item, unless the changes in fair value are not equal, which would result in hedge ineffectiveness. The Company assesses hedge ineffectiveness on a quarterly basis.
Changes in fair value of a hedging instrument that are excluded from the assessment of hedge effectiveness, also known as excluded components, are amortized over the period of the designated hedge.
Goodwill
On July 1, 2018, the Company also early adopted ASU 2017-04, Goodwill and Other: Simplifying the Accounting for Goodwill Impairment, and, as a result, updated its goodwill accounting policy as follows.
Goodwill represents the future economic benefits arising from assets acquired in a business combination that are not
separately recognized. The Company performs a qualitative impairment test at least annually to determine if the carrying value
of the reporting unit is in excess of its fair value. If a potential impairment is more likely than not, then the Company will
perform a single step quantitative test with any excess of carrying value over fair value recorded as an impairment charge in Intangible amortization and impairments in the Consolidated Statements of Income.
Fair Value Measurements

AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
In August 2018, the Financial Accounting Standards Board (the “FASB”) issued ASU 2018-13, Fair Value Measurements: Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, resulting in various disclosures related to fair value measurements being eliminated, modified or supplemented. ASU 2018-13 is effective for interim and annual periods beginning after December 15, 2019, with an option to early adopt any eliminated or modified disclosures, and to delay adoption of the additional disclosures, until the effective date. On September 1, 2018, the Company early adopted the eliminated and modified disclosures of ASU 2018-13 and, as a result, updated its financial statement disclosures accordingly. A modified narrative description of measurement uncertainty for level 3 fair value measurements was applied prospectively, with all other amendments applied retrospectively.
Recent Accounting Developments
In February 2016, the FASB issued ASU 2016-02, Leases, and subsequently issued several related amendments. The standard requires lessees to record right-of-use assets and lease liabilities arising from most operating leases on their 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 Company plans to adopt the standard using a modified retrospective method. The Company anticipates an increase in assets and liabilities on its Consolidated Condensed Balance Sheets for all lease obligations that are currently classified as operating leases, which consist primarily of real estate leases for office space, as well as additional disclosure related to its lease obligations. The Company does not expect the adoption to significantly impacted its Consolidated Statements of Income. The Company is finalizing its lease population and evaluating the discount rates used in determining the net present value of each of its lease liabilities to determine the impact of this standard on its Consolidated Condensed Balance Sheets.

3. | Investments in Marketable Securities

Investments in marketable securities at December 31, 2017 and September 30, 2018 were $77.8 million and $144.1 million, respectively. The following is a summary of the cost, gross unrealized gains and losses and fair value of Investments in marketable securities:

| December 31, 2017 |  | September 30, 2018
Cost | $ | 67.1 |  |  | $ | 128.3 |
Unrealized gains | 13.0 |  |  | 15.8 |
Unrealized losses | (2.3 | ) |  | (0.0 | )
Fair value | $ | 77.8 |  |  | $ | 144.1 |

In the three and nine months ended September 30, 2017, the Company received proceeds of $23.6 million and $81.9 million, respectively, from the sale of investments in marketable securities, and recorded net gains of $9.1 million and $24.2 million, respectively. In the three and nine months ended September 30, 2018, the Company received proceeds of $16.6 million and $42.6 million, respectively, from the sale of investments in marketable securities, and recorded net losses of $0.0 million and net gains of $4.0 million, respectively.

4. | Investments in Affiliates and Affiliate Sponsored Investment Products

In evaluating whether an investment must be consolidated, the Company evaluates the risk, rewards and significant terms of each of its Affiliates and other investments to determine if an investment is considered a voting rights entity (“VRE”) or a variable interest entity (“VIE”). An entity is a VRE when the total equity investment at risk is sufficient to enable the entity to finance its activities independently and when the equity holders have the obligation to absorb losses, the right to receive residual returns and the right to direct the activities of the entity that most significantly impact its economic performance. An entity is a VIE when it lacks one or more of the characteristics of a VRE, which, for the Company, are Affiliate investments structured as partnerships (or similar entities) where the limited partners lack substantive kick-out or substantive participation rights over the general partner. Assessing whether an entity is a VRE or VIE involves judgment. Upon the occurrence of certain events, management reviews and reconsiders its previous conclusion regarding the status of an entity as a VRE or a VIE.
The Company consolidates VREs when it has control over significant operating, financial and investment decisions of the entity. When the Company lacks such control, but is deemed to have significant influence, the Company accounts for the entity
10

AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
under the equity method. Other investments in which the Company does not have rights to exercise significant influence are recorded at fair value, with changes in fair value reflected within Investment and other income.
The Company consolidates VIEs 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 obligation to absorb losses of or the right to receive benefits from the entity that could potentially be significant to the VIE. The Company applies the equity method of accounting to VIEs where the Company is not the primary beneficiary, but has the ability to exercise significant influence over operating and financial matters of the VIE.
Investments in Affiliates
Substantially all of the Company’s Affiliates are considered VIEs and are either consolidated or accounted for under the equity method. A limited number of the Company’s Affiliates are considered VREs and most of these are accounted for under the equity method.
When an Affiliate is consolidated, the portion of the Affiliate’s management equity owners’ earnings attributable to Owners’ Allocation is included in Net income (non-controlling interests) in the Consolidated Statements of Income. Undistributed Operating and Owners’ Allocation attributable to Affiliate management equity owners, along with their share of any tangible or intangible net assets, are presented within Non-controlling interests on the Consolidated Condensed Balance Sheets. Affiliate equity interests where the holder has certain rights to demand settlement are presented, at their current redemption values, as Redeemable non-controlling interests on the Consolidated Condensed Balance Sheets. The Company periodically issues, sells and repurchases the equity of its consolidated Affiliates. Because these transactions take place between entities that are under common control, any gains or losses attributable to these transactions are required to be included within Additional paid-in capital in the Consolidated Condensed Balance Sheets, net of any related income tax effects, in the period the transactions occur.
When an Affiliate is accounted for under the equity method, the Company’s share of an Affiliate’s earnings or losses, net of amortization and impairments, is included in Equity method income (net) in the Consolidated Statements of Income and the Company’s interest in the Affiliate is reported in Equity method investments in Affiliates (net) in the Consolidated Condensed Balance Sheets. The Company’s share of income taxes incurred directly by Affiliates accounted for under the equity method is recorded within Income tax expense in the Consolidated Statements of Income.
The Company periodically evaluates its equity method Affiliates for impairment. In such impairment evaluations, the Company assesses whether or not the fair value of the investment has declined below its carrying value for a period considered to be other-than-temporary. If the Company determines that a decline in fair value below the carrying value of the investment is other-than-temporary, then the carrying value of the investment is reduced to its fair value and the reduction is recorded in Equity method income (net).
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, 2017 |  | September 30, 2018
| 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 | $ | 1,594.4 |  |  | $ | 2,765.7 |  |  | $ | 1,169.8 |  |  | $ | 2,530.8 |

The carrying value and maximum exposure to loss of equity method Affiliates considered VREs were $539.0 million and $524.5 million as of December 31, 2017 and September 30, 2018, respectively.
Affiliate Sponsored Investment Products
The Company’s Affiliates sponsor various investment products where they also act as the investment advisor. These investment products are typically owned primarily by third-party investors; however, certain products are funded with general partner and seed capital investments from the Company and its Affiliates.
11

AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
Third-party investors in Affiliate sponsored investment products are generally entitled to substantially all of the economics of these products, except for the management and performance fees earned by the Company’s consolidated Affiliates or any gains or losses attributable to the Company’s or its consolidated Affiliates’ investments in these products. As a result, the Company does not generally consolidate these products unless the Company’s or its Affiliate’s interest in the product is considered substantial. When the Company’s or its Affiliate’s interest is considered substantial and the products are consolidated, the Company retains the specialized investment company accounting principles of the underlying products, and all of the underlying investments are carried at fair value in Investments in marketable securities, with corresponding changes in the investments’ fair values reflected in Investment and other income. Purchases and sales of securities are presented within purchases and sales by Affiliate sponsored consolidated products in the Consolidated Statements of Cash Flows. When the Company or its Affiliates no longer control these products, due to a reduction in ownership or other reasons, the products are deconsolidated with only the Company’s or its consolidated Affiliate’s investment in the product reported from the date of deconsolidation.
The Company’s carrying value, and maximum exposure to loss from unconsolidated Affiliate sponsored investment products, is its or its consolidated Affiliate’s interest in the unconsolidated net assets of the respective products. The net assets of unconsolidated VIEs attributable to Affiliate sponsored investment products, and the Company’s carrying value and maximum risk of loss, were as follows:

| December 31, 2017 |  | September 30, 2018
| 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 | $ | 2,154.6 |  |  | $ | 10.2 |  |  | $ | 2,227.3 |  |  | $ | 1.0 |

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.
The Company has committed to co-invest in certain Affiliate sponsored investment products. As of September 30, 2018, these unfunded commitments were $130.4 million and may be called in future periods.
As of September 30, 2018, the Company was contingently liable, upon the achievement by certain Affiliates of specified financial targets, to make payments through 2020 related to the Company’s investments in these Affiliates. For its consolidated Affiliates, the Company was contingently liable for up to $12.7 million, and expected to make total payments of $4.5 million (of which $2.5 million are expected to be made in 2018). The present value of the total expected payments was $4.3 million. For its equity method Affiliates, the Company was contingently liable to make payments up to $150.0 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 15. In addition, in connection with an investment in an equity method Affiliate, 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 of its consolidated Affiliates operate under regulatory authorities that require the maintenance of minimum financial or capital requirements. Management is not aware of any significant violations of such requirements.

6. | Senior Debt

The Company has a $1.45 billion senior unsecured multicurrency revolving credit facility (the “revolver”). Subject to certain conditions, the Company may further increase the commitments under the revolver by up to $350.0 million. As of September 30, 2018, outstanding borrowings under the revolver were $415.0 million.
The Company also has a senior unsecured term loan facility (the “term loan” and, together with the revolver, the “credit facilities”). During the nine months ended September 30, 2018, the Company amended and refinanced the term loan to adjust
12

AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
the interest rates and maturity date, and to convert its denomination to pound sterling. The commercial terms of the loan otherwise remained the same. As discussed further in Note 8, the Company designated the term loan as a net investment hedge. As of September 30, 2018, the term loan totaled £290.0 million, and, subject to certain conditions, could be increased by an additional £50.0 million.
The revolver matures on September 30, 2020 and the term loan matures on May 31, 2021.
In October 2018, the Company further amended the term loan to convert its denomination from pound sterling to U.S. dollars, which is further described in Note 19.

7. | Convertible Securities

As of September 30, 2018, the Company had 5.15% junior convertible trust preferred securities outstanding (the “junior convertible securities”). Effective August 10, 2018 and in accordance with the convertible securities indenture, the Company adjusted the conversion rate of the junior convertible securities from 0.2500 shares of common stock to 0.2525 shares of common stock per $50.00 junior convertible security, equivalent to an adjusted conversion price of $198.02 per share of common stock. The adjustment was the result of the Company’s cumulative declared dividends on its common stock since the initiation of its dividend through August 2018.
8. Derivative Financial Instruments
The Company and its Affiliates may use derivative financial instruments to offset exposure to changes in interest rates, foreign currency exchange rates and markets.
On August 28, 2018, the Company entered into a pound sterling-denominated forward foreign currency contract (the “forward contract”) with a large financial institution (the “counterparty”) to deliver £285.8 million for $400.0 million in 2024. Concurrent with entering into the forward contract, the Company entered into a collar contract (the “collar contract”) with the same counterparty, for the same notional amounts and expiration date as the forward contract, through the sale of a put option with a lower strike price of 1.288 U.S. dollars per one pound sterling and the purchase of a call option with an upper strike price of 1.535 U.S. dollars per one pound sterling.
The forward contract and the collar contract were designated as net investment hedges against fluctuations in exchange rates on certain of the Company’s investments in Affiliates with the pound sterling as their functional currency.
The forward contract’s excluded component is recognized in earnings on a straight-line basis over the respective period of the forward contract as a reduction to Interest expense in the Consolidated Statements of Income. All other changes in the fair values of the forward contract and the collar contract are reported in Foreign currency translation gain (loss) in the Consolidated Statements of Comprehensive Income. The Company assesses hedge ineffectiveness on a quarterly basis. Any hedge ineffectiveness is recorded in Investment and other income in the Consolidated Statements of Income. For the three and nine months ended September 30, 2018, there was no ineffectiveness recorded.
The Company’s Affiliates use forward foreign currency contracts to hedge the risk of foreign exchange rate movements, none of which were significant.
The following table summarizes the Company’s and its Affiliates’ derivative financial instruments measured at fair value on a recurring basis. As of December 31, 2017, the Company and its Affiliates did not have any significant derivative financial instruments.

(1) | The excluded components are recorded as a reduction in Interest expense.

In the three and nine months ended September 30, 2018, the Company and its Affiliates did not have any significant gains (losses) reclassified from Accumulated other comprehensive income into earnings.
The terms of the Company’s forward contract and collar contract require the Company and the counterparty to post cash collateral in certain circumstances throughout the duration of the contracts. As of September 30, 2018, the Company held $3.1 million of cash collateral from the counterpary.
The counterparty to the Company’s derivative contracts is a large financial institution. The derivative contracts are governed by an International Swaps and Derivative Association (“ISDA”) Master Agreement with the counterparty, which provides for settlement netting and close-out netting between the Company and the counterparty, which are legally enforceable rights to setoff. The Company also actively monitors its counterparty credit risk related to derivative financial instruments. The Company’s derivative contracts include provisions to protect against counterparty rating downgrades, which in certain cases may result in the counterparty posting additional collateral to the Company, or give rise to a termination right. The Company considers set-off rights and counterparty credit risk in the valuation of its positions, and recognizes a credit valuation adjustment as appropriate.
In October 2018, the Company entered into an additional pound sterling-denominated forward foreign currency contract and an additional collar contract, which are further described in Note 19.

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. As of September 30, 2018, there were no changes to growth rates or discount rates that had a significant impact to contingent payment arrangements.
Affiliate equity repurchase obligations include agreements to repurchase Affiliate equity. As of September 30, 2018, there were no changes to growth or discount rates that had a significant impact to Affiliate equity repurchase obligations recorded in prior periods.
Investments Measured at NAV as a Practical Expedient
The Company’s Affiliates sponsor investment products in which the Company and its Affiliates may make general partner and seed capital investments. The Company uses the net asset value (“NAV”) of these investments as a practical expedient for their fair value and reports these products within Other investments and assets. 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:

| December 31, 2017 |  | September 30, 2018
Category of Investment | Fair Value |  | Unfunded Commitments |  | Fair Value |  | Unfunded Commitments
Private equity funds(1) | $ | 156.1 |  |  | $ | 98.8 |  |  | $ | 185.4 |  |  | $ | 130.4 |

Other investments(3) | $ | 165.0 |  |  | $ | 98.8 |  |  | $ | 192.8 |  |  | $ | 130.4 |

___________________________

(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 $80.1 million and $115.0 million as of December 31, 2017 and September 30, 2018, respectively.

Other Financial Assets and Liabilities Not Carried at Fair Value
The carrying amount of Receivables and Payables and accrued liabilities, which is reported in the Consolidated Condensed Balance Sheets, approximates fair value because of the short-term nature of these instruments. The carrying value of notes

receivable, which is reported in Other investments and 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 debt in the Consolidated Condensed Balance Sheets, approximates fair value because the credit facilities have variable interest based on selected short-term rates. The following table summarizes the Company’s other financial liabilities not carried at fair value:

Exercisable at September 30, 2018 | 0.1 |  |  | 136.33 |  |  | 2.7

For the nine months ended September 30, 2017 and 2018, the Company granted stock options with fair values of $0.8 million and $1.0 million, respectively. Stock options generally vest over a period of three to four years and expire seven years after the grant date. All options have been granted with exercise prices equal to the closing price of the Company’s common stock on the grant date. In certain circumstances, option awards also require certain performance conditions to be satisfied in order for the options to be exercised.
The fair value of options granted was estimated using the Black-Scholes option pricing model and were $48.05 and $48.64, per option, for the nine months ended September 30, 2017 and 2018, respectively. The weighted average grant date assumptions used to estimate the fair value of options granted were as follows:

|  | For the Nine Months Ended September 30,
|  | 2017 |  | 2018
Dividend yield |  | 0.5 | % |  | 0.8 | %
Expected volatility |  | 28.0 | % |  | 25.5 | %

Restricted Stock
The following table summarizes transactions in the Company’s restricted stock units:

| Restricted Stock Units |  | Weighted Average Grant Date Value
Unvested units - December 31, 2017 | 0.4 |  |  | $ | 162.32 |

Units forfeited | (0.0) |  |  | 152.09 |
Unvested units - September 30, 2018 | 0.6 |  |  | 172.58 |

For the nine months ended September 30, 2017 and 2018, the Company granted restricted stock unit awards with fair values of $36.7 million and $37.7 million, respectively. These awards were valued based on the closing price of the Company’s common stock on the grant date and the number of awards expected to be delivered. Awards containing vesting conditions generally require service over a period of three to four years and may also require the satisfaction of certain performance conditions.
14. Redeemable Non-Controlling Interests
19

AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
Affiliate equity interests provide holders with an equity interest in one of the Company’s 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. When the Company has an unconditional obligation to repurchase Affiliate equity interests, they are reclassified to Other liabilities. The following table presents the changes in Redeemable non-controlling interests:

|  | Redeemable Non-controlling interests
Balance, as of December 31, 2017 |  | $ | 811.9 |
Changes attributable to consolidated products |  | 64.9 |
Transfers to Other liabilities |  | (86.0 | )
Transfers from Non-controlling interests |  | 30.0 |
Changes in redemption value |  | 148.1 |
Balance, as of September 30, 2018 |  | $ | 968.9 |

15. 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, 2017 and 2018, distributions paid to Affiliate equity holders (non-controlling interests) were $266.8 million and $293.6 million, respectively.
The Company periodically repurchases Affiliate equity interests from and issues Affiliate equity interests to its Affiliate partners, its employees and its officers. For the nine months ended September 30, 2017 and 2018, the amount of cash paid for repurchases was $121.3 million and $104.3 million, respectively. For the nine months ended September 30, 2017 and 2018, the total amount of cash received for issuances was $8.8 million and $6.3 million, respectively.
Sales and repurchases of Affiliate equity generally occur at fair value; however, the Company also grants Affiliate equity to its Affiliate partners, its employees and its 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, the difference is recorded as compensation expense in Compensation and related expenses in the Consolidated Statements of Income over the requisite service period.
The following table presents Affiliate equity expense:

| For the Three Months Ended September 30, |  | For the Nine Months Ended September 30,
| 2017 |  | 2018 |  | 2017 |  | 2018
Controlling interest | $ | 2.3 |  |  | $ | 6.1 |  |  | $ | 9.4 |  |  | $ | 10.9 |
Non-controlling interests | 7.7 |  |  | 9.9 |  |  | 29.2 |  |  | 32.8 |
Total | $ | 10.0 |  |  | $ | 16.0 |  |  | $ | 38.6 |  |  | $ | 43.7 |

The following table presents unrecognized Affiliate equity expense:

| Controlling Interest |  | Remaining Life |  | Non-controlling Interests |  | Remaining Life
December 31, 2017 | $ | 33.3 |  |  | 5 years |  | $ | 95.9 |  |  | 6 years
September 30, 2018 | 36.8 |  |  | 5 years |  | 120.0 |  |  | 6 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 receivable was $12.4 million and $17.8 million at December 31, 2017 and September 30, 2018, respectively, and was included in Other investments and assets. The total

payable was $49.2 million and $28.7 million as of December 31, 2017 and September 30, 2018, 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 the Consolidated Statements of 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 presents the cumulative effect that ownership changes had on the controlling interest’s equity related only to Affiliate equity transactions that settled during the applicable periods:

| For the Three Months Ended September 30, |  | For the Nine Months Ended September 30,
| 2017 |  | 2018 |  | 2017 |  | 2018
Net income (controlling interest) | $ | 125.4 |  |  | $ | 124.9 |  |  | $ | 374.2 |  |  | $ | 394.9 |
Decrease in controlling interest paid-in capital from Affiliate equity issuances | (0.3 | ) |  | (0.5 | ) |  | (0.6 | ) |  | (3.8 | )
Decrease in controlling interest paid-in capital from Affiliate equity repurchases | (12.7 | ) |  | (31.7 | ) |  | (81.8 | ) |  | (63.8 | )
Net income (controlling interest) including the net impact of Affiliate equity transactions | $ | 112.4 |  |  | $ | 92.7 |  |  | $ | 291.8 |  |  | $ | 327.3 |

16. Income Taxes
On December 22, 2017, changes in U.S. tax laws were enacted which significantly revised U.S. corporate income tax by, among other things, lowering the corporate income tax rate, implementing a modified territorial tax system, and imposing a one-time transition tax on deemed repatriated foreign earnings and profits.
In 2017, the Company recorded a provisional one-time net benefit of $194.1 million as a reasonable estimate of the impact of the changes in U.S. tax laws. For the nine months ended September 30, 2018, the Company did not record any significant changes to its provisional amount. The impact of the changes in U.S. tax laws may be refined as further guidance, interpretations or information becomes available, upon completion by the Company of its evaluation of the impact of the changes in U.S. tax laws or upon the Company’s election of a policy with respect to the deferred tax effects of the Global Intangible Low Tax Income provisions of U.S. tax laws. The Company will finalize its accounting for the impact of changes in the U.S. tax laws in the fourth quarter of 2018.
The Company’s consolidated income tax provision includes taxes attributable to the controlling interest and, to a lesser extent, taxes attributable to the non-controlling interests.
The following table presents the consolidated provision for income taxes:

17. | Earnings Per Share

The calculation of Earnings per share (basic) is based on the weighted average number of shares of the Company’s common stock outstanding during the period. Earnings per share (diluted) is similar to Earnings per share (basic), 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:

| For the Three Months Ended September 30, |  | For the Nine Months Ended September 30,
| 2017 |  | 2018 |  | 2017 |  | 2018
Numerator |  |  |  |  |  |  |
Net income (controlling interest) | $ | 125.4 |  |  | $ | 124.9 |  |  | $ | 374.2 |  |  | $ | 394.9 |
Interest expense on convertible securities, net of taxes | 3.9 |  |  | 4.7 |  |  | 11.6 |  |  | 14.2 |
Net income (controlling interest), as adjusted | $ | 129.3 |  |  | $ | 129.6 |  |  | $ | 385.8 |  |  | $ | 409.1 |
Denominator |  |  |  |  |  |  |
Average shares outstanding (basic) | 55.8 |  |  | 53.1 |  |  | 56.3 |  |  | 53.9 |
Effect of dilutive instruments: |  |  |  |  |  |  |
Stock options and restricted stock units | 0.3 |  |  | 0.1 |  |  | 0.3 |  |  | 0.2 |
Convertible securities | 2.2 |  |  | 2.2 |  |  | 2.2 |  |  | 2.2 |
Average shares outstanding (diluted) | 58.3 |  |  | 55.4 |  |  | 58.8 |  |  | 56.3 |

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

| For the Three Months Ended September 30, |  | For the Nine Months Ended September 30,
| 2017 |  | 2018 |  | 2017 |  | 2018
Stock options and restricted stock units | 0.0 |  |  | 0.2 |  |  | 0.1 |  |  | 0.2 |

The Company may settle portions of its Affiliate equity purchases in shares of its common stock. Because it is the Company’s intention to settle these potential purchases in cash, the calculation of Average shares outstanding (diluted) excludes any potential dilutive effect from possible share settlements of Affiliate equity purchases.

19. | Subsequent Events

In October 2018, the Company amended its senior unsecured term loan facility to convert its denomination from pound sterling to U.S. dollars and to increase the borrowings to $450.0 million, with the ability to borrow an additional $75.0 million, subject to certain conditions. The Company pays interest on any outstanding obligations under the term loan at specified rates, based either on the U.S. dollar LIBOR rate or the prime rate as in effect from time to time. The other commercial terms of the term loan, including maturity date, remained the same. In connection with the conversion, the Company de-designated the term loan as a net investment hedge.

AFFILIATED MANAGERS GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
In October 2018, the Company entered into a pound sterling-denominated forward foreign currency contract to deliver £325.3 million for $450.0 million in 2021 and a collar contract with the same counterparty, for the same notional amounts and expiration date as the forward contract, through the sale of a put option with a lower strike price of 1.318 U.S. dollars per one pound sterling and the purchase of a call option with an upper strike price of 1.448 U.S. dollars per one pound sterling. The forward contracts and the collar contracts provide net settlement rights. The forward contract and the collar contract were designated as net investment hedges against fluctuations in exchange rates on certain of the Company’s investments in Affiliates with the pound sterling as their functional currency.

In addition, we provide centralized assistance to our Affiliates in strategic matters, marketing, distribution, product development and operations. As of September 30, 2018, our assets under management were $829.6 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 and maintain the same partnership approach, provide support and assistance in substantially the same manner, and our operating model is generally the same for all Affiliates. Furthermore, our Affiliates are all impacted by similar marketplace factors and operational trends. Therefore, our aggregate operating performance measures of assets under management, average assets under management and aggregate fees, which incorporate the assets under management and fees of all of our Affiliates, are important in providing management with a more comprehensive view of the operating performance and material trends across our entire business.
The following table presents our key operating performance measures:

|  | As of and for the Three Months Ended September 30, |  |  |  | As of and for the Nine Months Ended September 30, |  |

__________________________

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

25

inclusion of an Affiliate's financial results in our Consolidated Financial Statements. For certain of our equity method Affiliates, aggregate fees and financial results are reported one quarter in arrears.

(2) | Aggregate fees consists of the total asset and performance based fees earned by all of our Affiliates. Aggregate fees is an operating measure used by management to evaluate the operating performance and material trends across our entire business. Aggregate fees is provided in addition to, but not as a substitute for, our financial performance measures.

Assets Under Management
Through our Affiliates, we manage active return-oriented strategies, rather than passively-managed products, which typically carry lower fee rates. We continue to see demand for active return-oriented strategies, particularly in alternatives and multi-asset strategies, reflecting continued investor demand for returns that are less correlated to traditional equity and fixed income markets. In addition, we see both U.S. and non-U.S. investors increasing their allocations to global equities strategies. Investor demand for passively-managed products has continued, particularly for the large cap U.S. equity portions of client portfolios, and we have experienced outflows in U.S. equity strategies consistent with this industry-wide trend. We expect client demand for alternatives 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 present information regarding the composition of our assets under management by active return-oriented strategy and client type as of September 30, 2018:
_______________

(1) | Alternatives primarily include assets under management in fixed income/equity relative value, systematic diversified, private equity and real assets, and other alternatives strategies. Alternatives strategies generate earnings from (i) asset based fees from products subject to lock-ups or similar restrictions, (ii) asset based 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 8% of our assets under management as of September 30, 2018.

The following tables present changes in our assets under management by active return-oriented strategy and client type for the three and nine months ended September 30, 2018:

_________________________

(1) | Foreign exchange reflects the impact of translating into U.S. dollars the assets under management of Affiliates whose functional currency is not the U.S. dollar.

(2) Other primarily includes the assets under management attributable to Affiliate product transitions and transfers of our
interests in Affiliates.
In addition to assets under management, we also report average assets under management. This measure provides a more meaningful relationship to aggregate fees 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 were $834.1 billion and $834.5 billion for the three and nine months ended September 30, 2018, respectively, an increase of $43.5 billion or 6% and $68.0 billion or 9%, compared to the three and nine months ended September 30, 2017, respectively.
Aggregate Fees
Aggregate fees consists of the total asset and performance based fees earned by all of our Affiliates. Asset based fees include 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 based on investment performance, typically on an absolute basis or relative to a benchmark. Our ratio of asset based fees to average assets under management (“asset based fee ratio”) is calculated as asset based fees divided by average assets under management. Our asset based fee ratios may change as a result of new investments, client cash flows, market changes, foreign exchange, realizations and distributions or changes in contractual fees.
Our aggregate fees are generally determined by the level of our average assets under management, the composition of these assets across our active return-oriented strategies that realize different asset based fee ratios, and performance fees. Aggregate fees were $1,278.0 million in the three months ended September 30, 2018, an increase of $5.7 million or less than 1% compared to the three months ended September 30, 2017. The increase in our aggregate fees was the result of an increase in asset based fees of $24.0 million or 2%, partially offset by a decrease in performance fees of $18.3 million or 1%. The change in asset based fees was due to a 6% increase in our average assets under management, primarily in alternatives and U.S. equities strategies, partially offset by a 3% decline in our asset based fee ratio due to a change in the composition of our average assets under management and fee rate reductions at certain Affiliate products.
Aggregate fees were $4,210.7 million in the nine months ended September 30, 2018, an increase of $350.0 million or 9% compared to the nine months ended September 30, 2017. The increase in our aggregate fees was the result of an increase in asset based fees of $177.8 million or 5% and an increase in performance fees of $172.2 million or 4%. The change in asset based fees was due to a 9% increase in our average assets under management primarily in alternatives and global equities strategies, partially offset by a 3% decline in our asset based fee ratio due to a change in the composition of our average assets under management and fee rate reductions at certain Affiliate products.
Financial and Supplemental Financial Performance Measures
28

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) |  | 2017 |  | 2018 |  | % Change |  | 2017 |  | 2018 |  | % Change
Net income (controlling interest) |  | $ | 125.4 |  |  | $ | 124.9 |  |  | (0 | )% |  | $ | 374.2 |  |  | $ | 394.9 |  |  | 6 | %
Adjusted EBITDA (controlling interest)(1) |  | 256.3 |  |  | 237.8 |  |  | (7 | )% |  | 754.8 |  |  | 770.5 |  |  | 2 | %
Economic net income (controlling interest)(1) |  | 191.3 |  |  | 184.0 |  |  | (4 | )% |  | 563.2 |  |  | 594.8 |  |  | 6 | %

__________________________

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

Adjusted EBITDA (controlling interest) is an important supplemental financial performance measure for management as it provides a comprehensive view of our share of the financial performance of our business before interest, taxes, depreciation, amortization, impairments and adjustments to our contingent payment arrangements.
While our aggregate fees increased $5.7 million or less than 1% in the three months ended September 30, 2018, our Adjusted EBITDA (controlling interest) decreased $18.5 million or 7%, primarily due to a decrease in earnings at certain equity method Affiliates at which our share of earnings is contractually calculated using a formula based on a percentage of the Affiliate’s revenue less certain agreed-upon expenses. This change was also due to an increase in certain non-reoccurring Affiliate equity and compensation expenses, and a decrease in Investment and other income.
While our aggregate fees increased $350.0 million or 9% in the nine months ended September 30, 2018, our Adjusted EBITDA (controlling interest) increased $15.7 million or 2%, primarily due to a decrease in earnings at certain equity method Affiliates at which our share of earnings is contractually calculated using a formula based on a percentage of the Affiliate’s revenue less certain agreed-upon expenses. This change was also due to greater growth, proportionally, in aggregate fees at our equity method Affiliates in which we own less of an economic interest and a decrease in Investment in other income.
While Adjusted EBITDA (controlling interest) decreased $18.5 million or 7% in the three months ended September 30, 2018, our Net income (controlling interest) decreased $0.5 million or less than 1% due to decreases in our Interest expense and effective tax rate. In the nine months ended September 30, 2018, Adjusted EBITDA (controlling interest) increased $15.7 million or 2%, and our Net income (controlling interest) increased $20.7 million or 6%, primarily from decreases in our Interest expense and effective tax rate, partially offset by a $33.3 million expense ($25.0 million net of tax) to reduce the remaining carrying value of one of our equity method Affiliates to zero in the second quarter of 2018.
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. While Adjusted EBITDA (controlling interest) decreased $18.5 million or 7% in the three months ended September 30, 2018, our Economic net income controlling interest decreased $7.3 million or 4%, due to decreases in our Interest expense and effective tax rate. While Adjusted EBITDA (controlling interest) increased $15.7 million or 2% in the nine months ended September 30, 2018, our Economic net income (controlling interest) increased $31.6 million or 6%, primarily due to a decrease in our Interest expense and effective tax rate.
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 consolidated revenue, consolidated expenses, and Investment and other income, and our share of our equity method Affiliates’ financial results is reported (net of intangible amortization and impairments) in Equity method income (net).
Consolidated Revenue
The following table presents our consolidated Affiliate average assets under management and consolidated revenue:
29

| For the Three Months Ended September 30, |  |  |  | For the Nine Months Ended September 30, |  |
(in millions, except as noted) | 2017 |  | 2018 |  | % Change |  | 2017 |  | 2018 |  | % Change
Consolidated Affiliate average assets under management (in billions) | $ | 414.5 |  |  | $ | 425.3 |  |  | 3 | % |  | $ | 400.9 |  |  | $ | 427.6 |  |  | 7 | %
Consolidated revenue | $ | 585.7 |  |  | $ | 601.3 |  |  | 3 | % |  | $ | 1,700.9 |  |  | $ | 1,813.9 |  |  | 7 | %

Our consolidated revenue increased $15.6 million or 3% in the three months ended September 30, 2018, due to a $17.8 million or 3% increase from asset based revenue, partially offset by a $2.2 million or less than 1% decrease from performance fees. The increase in asset based revenue was primarily due to a 3% increase in consolidated Affiliate average assets under management primarily in alternatives and multi-asset and other strategies.
Our consolidated revenue increased $113.0 million or 7% in the nine months ended September 30, 2018, due to a $109.6 million or 6% increase from asset based revenue and a $3.4 million or less than 1% increase from performance fees. The increase in asset based revenue was primarily due to a 7% increase in consolidated Affiliate average assets under management, primarily in alternatives and global equities strategies.
Consolidated Expenses
The following table presents our consolidated expenses:

| For the Three Months Ended September 30, |  |  |  | For the Nine Months Ended September 30, |  |
| % Change |  | % Change
(in millions) | 2017 |  | 2018 |  |  | 2017 |  | 2018 |
Compensation and related expenses | $ | 238.7 |  |  | $ | 253.6 |  |  | 6 | % |  | $ | 722.9 |  |  | $ | 761.3 |  |  | 5 | %
Selling, general and administrative | 91.9 |  |  | 102.8 |  |  | 12 | % |  | 269.7 |  |  | 314.4 |  |  | 17 | %
Intangible amortization and impairments | 21.2 |  |  | 30.1 |  |  | 42 | % |  | 65.1 |  |  | 76.5 |  |  | 18 | %
Interest expense | 22.1 |  |  | 19.6 |  |  | (11 | )% |  | 67.6 |  |  | 62.6 |  |  | (7 | )%
Depreciation and other amortization | 4.8 |  |  | 5.3 |  |  | 10 | % |  | 14.9 |  |  | 16.5 |  |  | 11 | %
Other expenses (net) | 10.9 |  |  | 10.2 |  |  | (6 | )% |  | 35.9 |  |  | 33.4 |  |  | (7 | )%
Total consolidated expenses | $ | 389.6 |  |  | $ | 421.6 |  |  | 8 | % |  | $ | 1,176.1 |  |  | $ | 1,264.7 |  |  | 8 | %

Our consolidated expenses are primarily attributable to the non-controlling interests of our consolidated Affiliates in which we share in revenue without regard to expenses. For these Affiliates, the amount of their expenses attributable to the non-controlling interests, including compensation, is generally determined by the percentage of revenue allocated to expenses as part of the structured partnership interests in place at the respective Affiliate. Accordingly, increases in revenue generally will increase a consolidated Affiliate’s expenses attributable to the non-controlling interest and decreases in revenue will generally decrease a consolidated Affiliate’s expenses attributable to the non-controlling interest.
Compensation and related expenses increased $14.9 million or 6% in the three months ended September 30, 2018, due to a $10.9 million or 5% increase in compensation expenses attributable to the controlling interest, and a $4.0 million or 2% increase in compensation expenses attributable to the non-controlling interests. The increase in compensation expenses attributable to the controlling interest was primarily due to a non-reoccurring $3.7 million increase in Affiliate equity expense, a non-reoccurring $1.8 million increase in compensation expense, and a $1.6 million increase in share-based compensation expense.
Compensation and related expenses increased $38.4 million or 5% in the nine months ended September 30, 2018, primarily due to a $32.8 million or 5% increase from compensation expenses attributable to the non-controlling interests due to an increase in consolidated revenue, and a $6.4 million or 1% increase from compensation expenses attributable to the controlling interest, primarily due to a $4.0 million increase in share-based compensation expense.
Selling, general and administrative expenses increased $10.9 million or 12% in the three months ended September 30, 2018, primarily due to a $6.4 million or 7% increase in Affiliate-related expenses and a $4.8 million or 5% increase in distribution-related expenses from our adoption of ASU 2014-09, which were offset by an increase in consolidated revenue.
Selling, general and administrative expenses increased $44.7 million or 17% in the nine months ended September 30, 2018, primarily due to a $30.0 million or 11% increase in Affiliate-related expenses and a $15.5 million or 6% increase in distribution-related expenses from our adoption of ASU 2014-09, which were offset by an increase in consolidated revenue.
30

Intangible amortization and impairments increased $8.9 million or 42% and $11.4 million or 18% in the three and nine months ended September 30, 2018, respectively, due to a reduction in the expected period of economic benefit for certain assets. In the nine months ended September 30, 2018, this increase was partially offset by certain assets being fully amortized.
Interest expense decreased $2.5 million or 11% and $5.0 million or 7% in the three and nine months ended September 30, 2018, respectively, principally due to the redemption of our 6.375% senior unsecured notes due 2042, which decreased Interest expense $1.7 million or 8% and $8.7 million or 13%, respectively. In the nine months ended September 30, 2018, this decrease was partially offset by a $3.4 million or 5% increase in revolver and term loan interest expense due to increased interest rates.
There were no significant changes in Depreciation and other amortization in the three months ended September 30, 2018.
Depreciation and other amortization increased $1.6 million or 11% in the nine months ended September 30, 2018, primarily due to a $2.6 million or 48% increase attributable to the controlling interest, partially offset by a $1.0 million or 12% decrease at Affiliates attributable to the non-controlling interests.
There were no significant changes in Other expenses (net) in the three months ended September 30, 2018.
Other expenses (net) decreased $2.5 million or 7% in the nine months ended September 30, 2018, primarily due to an increase in gains resulting from the changes in the value of Affiliate equity repurchase obligations and contingent payment arrangements attributable to the controlling interest.
Equity Method Income (Net)
For equity method Affiliates, we use structured partnership interests in which our share of the Affiliate’s earnings or losses is contractually calculated, allocated and distributed using a formula based on a percentage of the Affiliate’s revenue less certain agreed-upon expenses. We also use structured partnership interests in which our share of the Affiliate’s earnings or losses is contractually calculated, allocated and distributed using a formula based on a percentage of the Affiliate’s revenue without regard to expenses. Our share of earnings from equity method Affiliates, net of amortization and impairments, is included in Equity method income (net).
The following table presents equity method Affiliate average assets under management and equity method revenue, as well as equity method earnings and equity method intangible amortization and impairments, which together form Equity method income (net):

Our equity method revenue decreased $9.9 million or 1% in the three months ended September 30, 2018, due to a $16.1 million or 2% decrease from performance fees, partially offset by a $6.2 million or 1% increase from asset based fees. The increase in asset based fees was due to a 9% increase in equity method Affiliate average assets under management, partially offset by a 7% decline in our asset based fee ratio due to a change in the composition of our average assets under management, including the recognition of assets under management prior to the recognition of revenue, and fee rate reductions at certain Affiliate products.
While equity method revenue decreased $9.9 million or 1% in the three months ended September 30, 2018, equity method earnings decreased $14.7 million or 15%, due to a decrease in earnings at certain Affiliates at which our share of earnings is contractually calculated using a formula based on a percentage of the Affiliate’s revenue less certain agreed-upon expenses.
31

Equity method intangible amortization and impairments decreased $3.7 million or 14% in the three months ended September 30, 2018, primarily due to changes in the expected period of the economic benefit, partially offset by certain assets being fully amortized.
Our equity method revenue increased $237.0 million or 11% in the nine months ended September 30, 2018, due to a $168.8 million or 8% increase from performance fees and a $68.2 million or 3% increase from asset based fees. The increase in asset based fees was due to an 11% increase in equity method Affiliate average assets under management, partially offset by a 7% decline in our asset based fee ratio due to a change in the composition of our average assets under management, including the recognition of assets under management prior to the recognition of revenue, and fee rate reductions at certain Affiliate products.
While equity method revenue increased $237.0 million or 11% in the nine months ended September 30, 2018, equity method earnings decreased $3.0 million or 1%, due to a decrease in earnings at certain Affiliates at which our share of earnings is contractually calculated using a formula based on a percentage of the Affiliate’s revenue less certain agreed-upon expenses.
Equity method intangible amortization and impairments increased $37.3 million or 52% in the nine months ended September 30, 2018, primarily due to a $33.3 million expense to reduce the remaining carrying value of one of our Affiliates to zero, and a $4.0 million increase in amortization due to a reduction in the expected period of economic benefit for certain assets.
Investment and other income
The following table presents our Investment and other income:

| For the Three Months Ended September 30, |  |  |  | For the Nine Months Ended September 30, |  |
(in millions) | 2017 |  | 2018 |  | % Change |  | 2017 |  | 2018 |  | % Change

Investment and other income decreased $5.1 million or 32% in the three months ended September 30, 2018, primarily due to a decrease in realized gains on the sale of marketable securities, partially offset by an increase in the fair value of other investments, primarily attributable to the controlling interest.
Investment and other income decreased $10.0 million or 21% in the nine months ended September 30, 2018, primarily due to a decrease in realized gains on the sale of marketable securities, partially offset by an increase in the fair value of other investments, primarily attributable to the controlling interest.
Income Tax Expense
The following table presents our Income tax expense:

| For the Three Months Ended September 30, |  |  |  | For the Nine Months Ended September 30, |  |
(in millions) | 2017 |  | 2018 |  | % Change |  | 2017 |  | 2018 |  | % Change

Income tax expense decreased $17.6 million or 27% in the three months ended September 30, 2018, primarily due to a decrease in Income before taxes (controlling interest) and a lower effective tax rate in 2018 due to the changes in U.S. tax laws enacted at the end of 2017.
Income tax expense decreased $42.1 million or 22% in the nine months ended September 30, 2018, primarily due to a decrease in Income before taxes (controlling interest) and a lower effective tax rate in 2018 due to the changes in U.S. tax laws enacted at the end of 2017.
Net Income
The previously discussed changes in revenue and expenses had the following effect on Net income:

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) is an important supplemental financial performance measure for management as it provides a comprehensive view of our share of the financial performance of our business before interest, taxes, depreciation, amortization, impairments and adjustments to our contingent payment arrangements. This non-GAAP performance measure is provided in addition to, but not as a substitute for, Net income (controlling interest) or other GAAP performance measures.
The following table presents 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,
(in millions) | 2017 |  | 2018 |  | 2017 |  | 2018
Net income (controlling interest) | $ | 125.4 |  |  | $ | 124.9 |  |  | $ | 374.2 |  |  | $ | 394.9 |

___________________________

(1) | Our consolidated Intangible amortization and impairments includes amortization attributable to our non-controlling interests. For our equity method Affiliates, we do not separately report intangible amortization and impairments in our Consolidated Statements of Income. Our share of these Affiliates’ amortization is reported in Equity method income (net).

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

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

Total | $ | 42.2 |  |  | $ | 44.9 |  |  | $ | 121.5 |  |  | $ | 166.9 |

Equity method intangible amortization and impairments includes a $33.3 million expense in the second quarter of 2018 to reduce the remaining carrying value of one of our equity method Affiliates to zero.

(2) | Other items include depreciation and adjustments to contingent payment arrangements.

Economic Net Income (controlling interest) and Economic Earnings Per Share
As supplemental information, we also provide non-GAAP performance 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
33

earnings per share to be important measures of our financial performance, as we believe they best represent 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 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, Net income (controlling interest) and Earnings per share (diluted) or other GAAP performance measures.
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 investments in 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 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.

(1) | See note (1) to the table in “Adjusted EBITDA (controlling interest).”

(2) In the second quarter of 2018, we recorded a $33.3 million expense to reduce the remaining carrying value of one of our equity method Affiliates to zero, which reduced intangible-related deferred taxes by $8.3 million.

(3) | For the three months ended September 30, 2017 and 2018, Other economic items were net of income tax expense of $0.3 million and $0.1 million, respectively. For the nine months ended September 30, 2017 and 2018, Other economic items were net of income tax expense of $1.4 million and $0.0 million, respectively.

(4) | For the nine months ended September 30, 2017, we adjusted our estimate of a contingent payment arrangement and, accordingly, recorded a loss attributable to the controlling interest of $1.4 million ($0.9 million net of tax). For the nine months ended September 30, 2018, we adjusted our estimate of a contingent payment arrangement and, accordingly, recorded a gain attributable to the controlling interest of $1.0 million ($0.8 million net of tax), all of which occurred in the second quarter of 2018.

Liquidity and Capital Resources
In the nine months ended September 30, 2018, we met our cash requirements 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 repayments of senior debt, repurchases of common stock, distributions to Affiliate equity holders, repurchases of Affiliate equity interests, the payment of cash dividends on our common stock and general working capital purposes. We also expect that principal uses 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, 2017 and September 30, 2018 were $439.5 million and $448.1 million, respectively. The following table summarizes our operating, investing and financing cash flow activities:

| For the Nine Months Ended September 30,
(in millions) | 2017 |  | 2018
Operating cash flow | $ | 800.5 |  |  | $ | 876.2 |
Investing cash flow | 4.9 |  |  | (20.9 | )
Financing cash flow | (871.5 | ) |  | (841.7 | )

Operating Cash Flow
In the nine months ended September 30, 2018, operating cash flows increased $75.7 million, which was primarily attributable to the controlling interest, principally from cash distributions of our share of equity method earnings and an increase in net income. Cash flow from operating activities attributable to the non-controlling interest did not change significantly in the nine months ended September 30, 2018.
Investing Cash Flow
In the nine months ended September 30, 2018, investing cash flows decreased $25.8 million, primarily due to a change in investment securities activity from a net sale of investment securities in 2017 of $49.1 million to net purchases in 2018 of $0.1 million, partially offset by a decrease in investments in Affiliates of $23.0 million.
Financing Cash Flow
In the nine months ended September 30, 2018, financing cash flows increased $29.8 million, primarily due to an increase in net borrowings of senior debt of $188.5 million and a decrease in net Affiliate equity repurchases of $14.5 million. These increases were partially offset by increases in net repurchases of shares of our common stock of $175.3 million.
Senior Debt and Convertible Securities
The following table presents the carrying value of our outstanding indebtedness:

(in millions) | December 31, 2017 |  | September 30, 2018
Senior bank debt | $ | 810.0 |  |  | $ | 792.9 |
Senior notes | 745.7 |  |  | 746.1 |
Senior debt | $ | 1,555.7 |  |  | $ | 1,539.0 |
Convertible securities | $ | 309.9 |  |  | $ | 311.8 |

Senior Bank Debt
We have a $1.45 billion senior unsecured multicurrency revolving credit facility (the “revolver”). Subject to certain conditions, we may further increase the commitments under the revolver by up to $350.0 million. As of September 30, 2018, outstanding borrowings under the revolver were $415.0 million.
We also have a senior unsecured term loan facility (the “term loan” and, together with the revolver, the “credit facilities”). During the nine months ended September 30, 2018, we amended and refinanced the term loan to adjust the interest rates and the
35

maturity date, and to convert our denomination to pound sterling. The commercial terms of the loan otherwise remained the same. As discussed further in Note 8 to the Consolidated Financial Statements, we designated the term loan as a net investment hedge. As of September 30, 2018, the term loan borrowings totaled £290.0 million and, subject to certain conditions, could be increased by an additional £50.0 million.
The revolver matures on September 30, 2020 and the term loan matures on May 31, 2021.
In October 2018, we further amended our senior unsecured term loan facility to convert its denomination from pound sterling to U.S. dollars and to increase the borrowings to $450.0 million, with the ability to borrow an additional $75.0 million, subject to certain conditions. We pay interest on any outstanding obligations under the term loan at specified rates, based either on the U.S. dollar LIBOR rate or the prime rate as in effect from time to time. The other commercial terms of the term loan, including maturity date, remained the same. In connection with the conversion, we de-designated the term loan as a net investment hedge.
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, 2018, 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.
Our ability to draw funding from the debt and capital markets globally is a significant source of liquidity for us, and our credit ratings, among other factors, allow us to access these sources of funding on favorable terms. We are currently rated A3 by Moody’s Investors Service and A- by S&P Global Ratings.
Convertible Securities
As of September 30, 2018, we had 5.15% junior convertible trust preferred securities outstanding (the “junior convertible securities”). Effective August 10, 2018 and in accordance with the convertible securities indenture, we adjusted the conversion rate of the junior convertible securities from 0.2500 shares of common stock to 0.2525 shares of common stock per $50.00 junior convertible security, equivalent to an adjusted conversion price of $198.02 per share of common stock. The adjustment was the result of our cumulative declared dividends on our common stock since the initiation of our dividend through August 2018.
Equity Distribution Program
We have equity distribution and forward equity agreements with several major securities firms under which we may, from time to time, 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, 2018, no sales have occurred under the equity distribution program.
Derivatives
On August 28, 2018, we entered into a pound sterling-denominated forward foreign currency contract (the “forward contract”) with a large financial institution (the “counterparty”) to deliver £285.8 million for $400.0 million in 2024. Concurrent with entering into the forward contract, we entered into a collar contract (the “collar contract”) with the same counterparty, for the same notional amounts and expiration date as the forward contract, through the sale of a put option with a lower strike price of 1.288 U.S. dollars per one pound sterling and the purchase of a call option with an upper strike price of 1.535 U.S. dollars per one pound sterling.
In October 2018, we entered into an additional pound sterling-denominated forward foreign currency contract to deliver £325.3 million for $450.0 million in 2021, and an additional collar contract with the same counterparty, for the same notional amounts and expiration date as the forward contract through the sale of a put option with a lower strike price of 1.318 U.S. dollars per one pound sterling and the purchase of a call option with an upper strike price of 1.448 U.S. dollars per one pound sterling. The forward contracts and the collar contracts provide net settlement rights.
The forward contracts and the collar contracts were designated as net investment hedges against fluctuations in exchange rates on certain of our investments in Affiliates with the pound sterling as their functional currency. See Note 8 of the Consolidated Financial Statements.
36

Affiliate Equity
Many of our consolidated 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, 2018, our current redemption value of $968.9 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 paid $104.3 million for repurchases and received $6.3 million for issuances of Affiliate equity during the nine months ended September 30, 2018, and expect to repurchase a total of approximately $125 million in 2018. In the event of a repurchase, we become the owner of the cash flow associated with the repurchased equity.
Commitments
See Note 5 of the Consolidated Financial Statements.
Share Repurchases
During the three and nine months ended September 30, 2018, we repurchased 0.8 million and 2.5 million shares of our common stock, respectively, at an average price per share of $146.85 and $166.19, respectively. As of September 30, 2018, we had 2.5 million shares remaining under our authorized share repurchase program, which has no expiry.
Contractual Obligations
The following table summarizes our contractual obligations as of September 30, 2018. Contractual debt obligations include the cash payment of fixed interest.

Recent Accounting Developments
See Note 2 of the Consolidated Financial Statements.

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, 2018. Please refer to the below as well as the additional disclosures in Item 7A of our 2017 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 $4.7 million and $2.1 million, respectively, as of September 30, 2018, and annual changes to Income before income taxes (controlling interest) of $1.1 million and $0.3 million, respectively.
Derivative Risk
From time to time, we and our Affiliates seek to offset exposure to changes in interest rates, foreign currency exchange rates and markets by entering into derivative financial instruments. There can be no assurance that our or our Affiliates’ derivative financial instruments will meet their overall objective or that we or our Affiliates will be successful in entering into such instruments in the future. Further, if our or our Affiliates’ derivative counterparties fail to honor their obligations in a timely manner, including any obligations to return posted collateral, our liquidity and results of operations could be adversely impacted.
In the three months ended September 30, 2018, we entered into derivative financial instruments to mitigate the potential risk of changes in foreign currency exchange rates. See Note 8 of the Consolidated Financial Statements.

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 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.
