ARTISAN PARTNERS ASSET MANAGEMENT INC.

Notes to Unaudited Consolidated Financial Statements

(U.S. currencies in thousands, except share and per share amounts and as otherwise indicated)

Note 1. Nature of Business and Organization

Nature of Business

Artisan Partners Asset Management Inc. (“APAM”), through its subsidiaries, is an investment management firm focused on providing high-value added, active investment strategies to sophisticated clients globally. APAM and its subsidiaries are hereafter referred to collectively as “Artisan” or the “Company”.

Artisan’s autonomous investment teams manage a broad range of U.S., non-U.S. and global investment strategies that are diversified by asset class, market cap and investment style. Strategies are offered through multiple investment vehicles to accommodate a broad range of client mandates. Artisan offers its investment management services primarily to institutions and through intermediaries that operate with institutional-like decision-making processes and have long-term investment horizons.

Organization

On March 12, 2013, APAM completed its initial public offering (the “IPO”). APAM was formed for the purpose of becoming the general partner of Artisan Partners Holdings LP (“Artisan Partners Holdings” or “Holdings”) in connection with the IPO. Holdings is a holding company for the investment management business conducted under the name “Artisan Partners”. The reorganization (“IPO Reorganization”) established the necessary corporate structure to complete the IPO while at the same time preserving the ability of the firm to conduct operations through Holdings and its subsidiaries.

As the sole general partner, APAM controls the business and affairs of Holdings. As a result, APAM consolidates Holdings’ financial statements and records a noncontrolling interest for the equity interests in Holdings held by the limited partners of Holdings. At September 30, 2020, APAM held approximately 78% of the equity ownership interest in Holdings.

Holdings, together with its wholly owned subsidiary, Artisan Investments GP LLC, controls a 100% interest in Artisan Partners Limited Partnership (“APLP”), a multi-product investment management firm that is the principal operating subsidiary of Artisan Partners Holdings. APLP is registered as an investment adviser with the U.S. Securities and Exchange Commission under the Investment Advisers Act of 1940. APLP provides investment advisory services to traditional separate accounts and pooled investment vehicles, including Artisan Partners Funds, Inc. (“Artisan Funds”), Artisan Partners Global Funds plc (“Artisan Global Funds”), and Artisan sponsored private funds (“Artisan Private Funds”). Artisan Funds are a series of open-end, diversified mutual funds registered under the Investment Company Act of 1940, as amended. Artisan Global Funds is a family of Ireland-domiciled UCITS.

Note 2. Summary of Significant Accounting Policies

Basis of presentation

The accompanying financial statements are unaudited. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of such consolidated financial statements have been included. Such interim results are not necessarily indicative of full year results.

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting and accordingly they do not include all of the information and footnotes required in the annual consolidated financial statements and accompanying footnotes.

The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. As a result, the interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in APAM’s latest annual report on Form 10-K.

The accompanying financial statements were prepared in accordance with U.S. GAAP and related rules and regulations of the SEC. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates or assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from these estimates or assumptions.

Principles of consolidation

Artisan’s policy is to consolidate all subsidiaries or other entities in which it has a controlling financial interest. The consolidation guidance requires an analysis to determine if an entity should be evaluated for consolidation using the voting interest entity (“VOE”) model or the variable interest entity (“VIE”) model. Under the VOE model, controlling financial interest is generally defined as a majority ownership of voting interests. Under the VIE model, controlling financial interest is defined as (i) the power to direct activities that most significantly impact the economic performance of the entity and (ii) the right to receive potentially significant benefits or the obligation to absorb potentially significant losses.

7

Artisan generally consolidates VIEs in which it meets the power criteria and holds an equity ownership interest of greater than 10%. The consolidated financial statements include the accounts of APAM and all subsidiaries or other entities in which APAM has a direct or indirect controlling financial interest. All material intercompany balances have been eliminated in consolidation.

Artisan serves as the investment adviser to Artisan Funds, Artisan Global Funds and Artisan Private Funds. Artisan Funds and Artisan Global Funds are corporate entities the business and affairs of which are managed by their respective boards of directors. The shareholders of the funds retain voting rights, including rights to elect and reelect members of their respective boards of directors. Each series of Artisan Funds is a VOE and is separately evaluated for consolidation under the VOE model. The shareholders of Artisan Global Funds lack simple majority liquidation rights, and as a result, each sub-fund of Artisan Global Funds is evaluated for consolidation under the VIE model. Artisan Private Funds are also evaluated for consolidation under the VIE model because third-party equity holders of the funds generally lack the ability to divest Artisan of its control of the funds.

From time to time, the Company makes investments in Artisan Funds, Artisan Global Funds, and Artisan Private Funds. If the investment results in a controlling financial interest, APAM consolidates the fund, and the underlying activity of the entire fund is included in Artisan’s Unaudited Consolidated Financial Statements. As of September 30, 2020, Artisan had a controlling financial interest in three sub-funds of Artisan Global Funds and three Artisan Private Funds and, as a result, these funds are included in Artisan’s Unaudited Consolidated Financial Statements. Because these consolidated investment products meet the definition of investment companies under U.S. GAAP, Artisan has retained the specialized industry accounting principles for investment companies in the consolidated financial statements. See Note 6, “Variable Interest Entities and Consolidated Investment Products” for additional details.

Recent accounting pronouncements

Accounting standards adopted as of January 1, 2020

In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The capitalized implementation costs will be expensed over the term of the hosting arrangement. The Company adopted the new guidance on January 1, 2020. The Company capitalized $868 thousand of software implementation costs and recorded $40 thousand of related amortization expense during the nine months ended September 30, 2020.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses, which requires entities to measure credit losses on financial assets based on expected losses rather than incurred losses. The guidance was effective on January 1, 2020 and requires a modified retrospective approach to adoption. The adoption of this guidance did not have an impact on the consolidated financial statements.

Note 3. Investment Securities

The disclosures below include details of Artisan’s investments, excluding money market funds and consolidated investment products. Investments held by consolidated investment products are described in Note 6, “Variable Interest Entities and Consolidated Investment Products”.

	As of September 30, 2020		As of December 31, 2019
Investments in equity securities	$	4,197	$	7,543
Investments in equity securities accounted for under the equity method	2,540		16,335
Total investment securities	$	6,737	$	23,878

Artisan’s investments in equity securities consist of investments in shares of Artisan Funds, Artisan Global Funds and Artisan Private Funds. The table below presents the net investment income activity related to these investment securities:

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

Note 4. Fair Value Measurements

The table below presents information about Artisan’s assets and liabilities that are measured at fair value and the valuation techniques Artisan utilized to determine such fair value. The financial instruments held by consolidated investment products are excluded from the table below and are presented in Note 6, “Variable Interest Entities and Consolidated Investment Products”.

In accordance with ASC 820, fair value is defined as the price that Artisan would receive upon selling an investment in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. The following three-tier fair value hierarchy prioritizes the inputs used in measuring fair value:

•Level 1 – Observable inputs such as quoted (unadjusted) market prices in active markets for identical securities.

•Level 2 – Other significant observable inputs (including but not limited to quoted prices for similar instruments, interest rates, prepayment speeds, credit risk, etc.).

•Level 3 – Significant unobservable inputs (including Artisan’s own assumptions in determining fair value).

The following provides the hierarchy of inputs used to derive fair value of Artisan’s assets and liabilities that are financial instruments as of September 30, 2020 and December 31, 2019:

	Assets and Liabilities at Fair Value
	Total		NAV Practical Expedient (No Fair Value Level)		Level 1		Level 2		Level 3
September 30, 2020
Assets
Money market funds	$	70,854	$	—	$	70,854	$	—	$	—
Equity securities	6,737		50		6,687		—		—
December 31, 2019
Assets
Money market funds	$	30,673	$	—	$	30,673	$	—	$	—
Equity securities	23,878		15,068		8,810		—		—

Fair values determined based on Level 1 inputs utilize quoted market prices for identical assets. Level 1 assets generally consist of money market funds, open-end mutual funds and UCITS funds. Equity securities without a fair value level consist of the Company’s investments in Artisan Private Funds, which are measured at the underlying fund’s net asset value (“NAV”), using the ASC 820 practical expedient. The NAV is provided by the fund and is derived from the fair values of the underlying investments as of the reporting date. Cash maintained in demand deposit accounts is excluded from the table above.

Note 5. Borrowings

Artisan’s borrowings consist of the following as of September 30, 2020 and December 31, 2019:

	Maturity	Outstanding Balance		Interest Rate Per Annum
Revolving credit agreement	August 2022	$	—	NA
Senior notes
Series C	August 2022	90,000		5.82	%
Series D	August 2025	60,000		4.29	%
Series E	August 2027	50,000		4.53	%
Total borrowings		$	200,000

The fair value of borrowings was approximately $205.3 million as of September 30, 2020. Fair value was determined based on future cash flows, discounted to present value using current market interest rates. The inputs are categorized as Level 2 in the fair value hierarchy, as defined in Note 4, “Fair Value Measurements”.

Interest expense incurred on the unsecured notes and revolving credit agreement was $2.6 million for the three months ended September 30, 2020 and 2019, and $7.7 million and $7.9 million for the nine months ended September 30, 2020 and 2019, respectively.

As of September 30, 2020, the aggregate maturities of debt obligations, based on their contractual terms, are as follows:

2020	$	—
2021	—
2022	90,000
2023	—
2024	—
Thereafter	110,000
Total	$	200,000

Note 6. Variable Interest Entities and Consolidated Investment Products

Artisan serves as the investment adviser for various types of investment products, consisting of both VIEs and VOEs. Artisan consolidates an investment product if it has a controlling financial interest in the entity. Any such entities are collectively referred to herein as consolidated investment products or CIPs.

As of September 30, 2020, Artisan is considered to have a controlling financial interest in three sub-funds of Artisan Global Funds and three Artisan Private Funds, with an aggregate direct equity investment in the consolidated investment products of $51.2 million.

Artisan’s maximum exposure to loss in connection with the assets and liabilities of CIPs is limited to its direct equity investment, while the potential benefit is limited to the management and performance fees received and the return on its equity investment. With the exception of Artisan’s direct equity investment, the assets of CIPs are not available to Artisan’s creditors, nor are they available to Artisan for general corporate purposes. In addition, third-party investors in the CIPs have no recourse to the general credit of the Company.

Management and performance fees earned from CIPs are eliminated from revenue upon consolidation. See Note 14, “Related Party Transactions” for additional information on management and performance fees earned from CIPs.

Third-party investors’ ownership interest in CIPs is presented as redeemable noncontrolling interest in the Unaudited Condensed Consolidated Statements of Financial Condition as third-party investors have the right to withdraw their capital, subject to certain conditions. Net income attributable to third-party investors is reported as net income attributable to noncontrolling interests - consolidated investment products in the Unaudited Consolidated Statements of Operations.

During the nine months ended September 30, 2020, the Company determined that it no longer had a controlling financial interest in one sub-fund of Artisan Global Funds as a result of third party capital contributions. Upon loss of control, the VIE was deconsolidated and the related assets, liabilities, and equity of the fund were derecognized from the Company’s Unaudited Condensed Consolidated Statements of Financial Condition. There was no net impact to the Unaudited Consolidated Statements of Operations for the nine months ended September 30, 2020. Artisan generally does not recognize a gain or loss upon deconsolidation of investment products because the assets and liabilities of CIPs are carried at fair value. Upon deconsolidation, Artisan’s $1.5 million direct equity investment was reclassified from investment assets of consolidated investment products to investment securities in the Company’s Unaudited Condensed Consolidated Statements of Financial Condition.

As of September 30, 2020, Artisan held direct equity investments of $2.5 million in VIEs for which the Company does not hold a controlling financial interest. These direct equity investments consisted of seed investments in sub-funds of Artisan Global Funds and Artisan Private Funds, both of which are accounted for under the equity method of accounting because Artisan has significant influence over the funds.

Fair Value Measurements - Consolidated Investment Products

The carrying value of CIPs’ investments is also their fair value. Short and long positions on equity securities are valued based upon closing prices of the security on the exchange or market designated by the accounting agent or pricing vendor as the principal exchange. The closing price may represent last sale price, official closing price, a closing auction or other information depending on market convention. Short and long positions on fixed income instruments are valued at market value. Market values are generally evaluations based on the judgment of pricing vendors, which may consider, among other factors, the prices at which securities actually trade, broker-dealer quotations, pricing formulas, estimates of market values obtained from yield data relating to investments or securities with similar characteristics and/or discounted cash flow models that might be applicable.

10

The following tables present the fair value hierarchy levels of assets and liabilities held by CIPs measured at fair value as of September 30, 2020 and December 31, 2019:

	Assets and Liabilities at Fair Value
	Total		Level 1		Level 2		Level 3

Note 7. Noncontrolling interests - Holdings

Net income attributable to noncontrolling interests - Artisan Partners Holdings in the Unaudited Consolidated Statements of Operations represents the portion of earnings or loss attributable to the equity ownership interests in Holdings held by the limited partners of Holdings. As of September 30, 2020, APAM held approximately 78% of the equity ownership interests in Holdings.

Limited partners of Artisan Partners Holdings are entitled to exchange partnership units (along with a corresponding number of shares of Class B or C common stock of APAM) for shares of Class A common stock from time to time (the “Holdings Common Unit Exchanges”). The Holdings Common Unit Exchanges increase APAM’s equity ownership interest in Holdings and result in an increase to deferred tax assets and amounts payable under the tax receivable agreements. See Note 11, “Income Taxes and Related Payments”.

In order to maintain the one-to-one correspondence of the number of Holdings partnership units and APAM common shares, Holdings will issue one general partner (“GP”) unit to APAM for each share of Class A common stock issued by APAM. For the nine months ended September 30, 2020, APAM’s equity ownership interest in Holdings increased as a result of the following transactions:

	Holdings GP Units	Limited Partnership Units	Total	APAM Ownership %
Balance at December 31, 2019	56,429,825	21,372,029	77,801,854	73	%
2020 Follow-On Offering	1,802,326	(1,802,326)	—	2	%
Holdings Common Unit Exchanges	2,420,124	(2,420,124)	—	3	%
Issuance of APAM Restricted Shares(1)	916,085	—	916,085	—	%
Delivery of Shares Underlying RSUs (1)	24,233	—	24,233	—	%
Restricted Share Award Net Share Settlement (1)	(126,971)	—	(126,971)	—	%
Forfeitures of Holdings GP Units from Employee Terminations (1)	(40,101)	—	(40,101)	—	%
Balance at September 30, 2020	61,425,521	17,149,579	78,575,100	78	%

(1) The impact of the transaction on APAM’s ownership percentage was less than 1%.

Changes in ownership of Holdings are accounted for as equity transactions because APAM continues to have a controlling interest in Holdings. Additional paid-in capital and noncontrolling interests - Artisan Partners Holdings in the Unaudited Condensed Consolidated Statements of Financial Condition are adjusted to reallocate Holdings’ historical equity to reflect the change in APAM’s ownership of Holdings.

The reallocation of equity had the following impact on the Unaudited Condensed Consolidated Statements of Financial Condition:

Statement of Financial Condition	For the Nine Months Ended September 30,
	2020		2019
Additional paid-in capital	$	(740)	$	(2,455)
Noncontrolling interests - Artisan Partners Holdings	742		2,501
Accumulated other comprehensive income (loss)	(2)		(46)
Net impact to financial condition	$	—	$	—

In addition to the reallocation of historical equity, the change in ownership resulted in an increase to deferred tax assets and additional paid-in capital of $2.0 million and $0.6 million for the nine months ended September 30, 2020 and 2019, respectively.

Note 8. Stockholders’ Equity

APAM - Stockholders’ Equity

APAM had the following authorized and outstanding equity as of September 30, 2020 and December 31, 2019, respectively:

		Outstanding
	Authorized	As of September 30, 2020	As of December 31, 2019	Voting Rights (1)	Economic Rights

Class C, par value $0.01 per share	400,000,000	11,630,164	13,568,665	1 vote per share	None
(1) The Company’s employees to whom Artisan has granted equity have entered into a stockholders agreement with respect to all shares of APAM common stock they have acquired from the Company and any shares they may acquire from the Company in the future, pursuant to which they granted an irrevocable voting proxy to a Stockholders Committee. As of September 30, 2020, Artisan’s employees held 5,186,737 restricted shares of Class A common stock and all 5,519,415 outstanding shares of Class B common stock, all of which were subject to the agreement.

APAM is dependent on cash generated by Holdings to fund any dividends. Generally, Holdings will make distributions to all of its partners, including APAM, based on the proportionate ownership each holds in Holdings. APAM will fund dividends to its stockholders from its proportionate share of those distributions after provision for its taxes and other obligations. APAM declared and paid the following dividends per share during the three and nine months ended September 30, 2020 and 2019:

Type of Dividend	Class of Stock	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
		2020		2019		2020		2019
Quarterly	Class A Common	$	0.67	$	0.60	$	1.96	$	1.71
Special Annual	Class A Common	$	—	$	—	$	0.60	$	1.03

The following table summarizes APAM’s stock transactions for the nine months ended September 30, 2020:

	Total Stock Outstanding	Class A Common Stock(1)	Class B Common Stock	Class C Common Stock

Balance at September 30, 2020	78,575,100	61,425,521	5,519,415	11,630,164
(1) There were 304,570 and 297,891 restricted stock units outstanding at September 30, 2020 and December 31, 2019, respectively. In addition, there were 60,000 performance share units outstanding at September 30, 2020. Based on the current status of the market and performance conditions, the 60,000 unvested performance share units would ultimately result in the issuance of 90,000 shares of Class A common stock if all other vesting conditions were met. Restricted stock units and performance share units are not reflected in the table because they are not considered outstanding or issued stock.

Each Class A, Class B, Class D and Class E common unit of Holdings (together with the corresponding share of Class B or Class C common stock) is exchangeable for one share of Class A common stock. The corresponding shares of Class B and Class C common stock are immediately canceled upon any such exchange.

13

Upon termination of employment with Artisan, an employee-partner’s Class B common units are exchanged for Class E common units and the corresponding shares of Class B common stock are canceled. APAM issues the former employee-partner a number of shares of Class C common stock equal to the former employee-partner’s number of Class E common units. Class E common units are exchangeable for Class A common stock subject to the same restrictions and limitations on exchange applicable to the other common units of Holdings.

Artisan Partners Holdings - Partners’ Equity

Holdings makes distributions of its net income to the holders of its partnership units for income taxes as required under the terms of the partnership agreement and also makes additional distributions under the terms of the partnership agreement. The distributions are recorded in the financial statements on the declaration date, or on the payment date in lieu of a declaration date. Holdings’ partnership distributions for the three and nine months ended September 30, 2020 and 2019, were as follows:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2020		2019		2020		2019
Holdings Partnership Distributions to Limited Partners	$	20,923	$	21,828	$	60,245	$	70,152
Holdings Partnership Distributions to APAM	70,024		53,423		181,379		166,307
Total Holdings Partnership Distributions	$	90,947	$	75,251	$	241,624	$	236,459

The distributions are recorded as a reduction to consolidated stockholders’ equity, with the exception of distributions made to APAM, which are eliminated upon consolidation.

(1) Separate account revenue consists of management fees and performance fees earned from vehicles other than Artisan Funds or Artisan Global Funds, which includes traditional separate accounts, Artisan-branded collective investment trusts and funds (both public and private) that Artisan advises, including Artisan Private Funds.
(2) All management fees and performance fees from consolidated investment products are eliminated upon consolidation and therefore are omitted from this table.

Performance fees are subject to the uncertainty of market volatility, and as a result, the entire amount of the variable consideration related to performance fees is constrained until the end of each measurement period. At the end of the quarterly or annual measurement period, revenue is recorded for the actual amount of performance fees earned during that period because the uncertainty has been resolved. For performance fees with annual measurement periods, revenue recognized in the current quarter relates to performance obligations that were partially satisfied in prior periods.

The following table presents the balances of receivables related to contracts with customers:

	As of September 30, 2020		As of December 31, 2019
Customer
Artisan Funds	$	7,289	$	6,703
Artisan Global Funds	3,524		3,588
Separate accounts	80,930		69,413
Total receivables from contracts with customers	$	91,743	$	79,704
Non-customer receivables	6,677		2,164
Accounts receivable	$	98,420	$	81,868

Artisan Funds and Artisan Global Funds are billed on the last day of each month. Artisan Funds and Artisan Global Funds make payments on the same day the invoice is received for the majority of the invoiced amount. The remainder of the invoice is generally paid in the month following receipt of the invoice. Separate account clients are generally billed on a monthly or quarterly basis, with payments due within 30 days of billing. Artisan had no other contract assets or liabilities from contracts with customers as of September 30, 2020 or December 31, 2019.

Note 10. Compensation and Benefits

Total compensation and benefits consists of the following:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2020		2019		2020		2019
Salaries, incentive compensation and benefits (1)	$	99,517	$	89,969	$	288,186	$	267,198

Total compensation and benefits	$	108,657	$	99,847	$	315,578	$	300,615
(1) Excluding restricted share-based award compensation expense

Incentive compensation

Cash incentive compensation paid to members of Artisan’s investment teams and members of its distribution teams is generally based on formulas that are tied directly to revenues. These payments are made in the quarter following the quarter in which the incentive was earned with the exception of fourth quarter payments which are paid in the fourth quarter of the year. Cash incentive compensation paid to most other employees is discretionary and subjectively determined based on individual performance and Artisan’s overall results during the applicable year and is generally paid on an annual basis.

Restricted share-based awards

Artisan has registered 14,000,000 shares of Class A common stock for issuance under the 2013 Omnibus Incentive Compensation Plan (the “Plan”). Pursuant to the Plan, APAM has granted a combination of restricted stock awards, restricted stock units, and performance share units (collectively referred to as “restricted share-based awards” or "awards") of Class A common stock to employees.

Standard Restricted Shares. Standard restricted shares are generally subject to a pro rata five-year service vesting condition.

Career Shares. Career shares are generally subject to both (i) a pro rata five-year service vesting condition and (ii) a qualifying retirement (as defined in the award agreement).

Franchise Shares. Like career shares, franchise shares are generally subject to both (i) a pro rata five-year service vesting condition and (ii) a qualifying retirement condition. In addition, franchise shares, which are only granted to investment team members, are subject to a Franchise Protection Clause, which provides that the number of shares that ultimately vest depends on whether certain conditions relating to client cash flows are met. If such conditions are not met, compensation cost will be reversed for any shares that do not vest.

15

Performance Share Units (PSUs). PSUs are generally subject to (i) a three-year service vesting condition, (ii) certain performance conditions related to the Company's operating margin and total shareholder return compared to a peer group during a three-year performance period, and (iii) for one-half of the PSUs eligible to vest at the end of the performance period, a qualifying retirement condition. The number of shares of Class A common stock that are ultimately issued in connection with each PSU award will depend upon the outcome of the performance, market and qualified retirement conditions. For the portion of a PSU award with a "performance condition" under ASC 718, expense is recognized over the service period if it is probable that the performance condition will be achieved.

Compensation expense is recognized based on the estimated grant date fair value on a straight-line basis over the requisite service period of the award. The initial requisite service period is generally five years for restricted stock awards and restricted stock units, and three years for performance share units. The fair value of each award is equal to the market price of the Company's common stock on the grant date, except for performance share units with a "market condition" performance metric under ASC 718, which have a grant-date fair value based on a Monte Carlo valuation model.

Unvested restricted share-based awards are subject to forfeiture. The Company’s accounting policy is to record the impact of forfeitures when they occur. Grantees are generally entitled to dividends or dividend equivalents on unvested and vested awards. 4,631,934 shares of Class A common stock were reserved and available for issuance under the Plan as of September 30, 2020.

During the nine months ended September 30, 2020, Artisan granted 916,085 restricted stock awards, 3,370 restricted stock units, and 60,000 performance share units of Class A common stock to employees of the Company. Total compensation expense associated with the 2020 grant is expected to be approximately $34.1 million.

The following tables summarize the restricted share-based award activity for the nine months ended September 30, 2020:

	Weighted-Average Grant Date Fair Value		Restricted Stock Awards and Restricted Stock Units
Unvested at January 1, 2020	$	35.00	5,005,422
Granted	33.80		919,455
Forfeited	30.71		(40,101)
Vested	32.59		(588,144)
Unvested at September 30, 2020	$	35.09	5,296,632

	Weighted-Average Grant Date Fair Value		Performance Share Units
Unvested at January 1, 2020	$	—	—
Granted	52.45		60,000
Forfeited	—		—
Vested	—		—
Unvested at September 30, 2020	$	52.45	60,000

Based on the current status of the market and performance conditions, the 60,000 unvested performance share units would ultimately result in the issuance of 90,000 shares of Class A common stock if all other vesting conditions were met.

The unrecognized compensation expense for all unvested awards as of September 30, 2020 was $88.0 million with a weighted average recognition period of 3.3 years remaining.

During the nine months ended September 30, 2020, the Company withheld a total of 126,971 restricted shares and paid $4.5 million as a result of net share settlements to satisfy employee tax withholding obligations. These net share settlements had the effect of shares repurchased and retired by the Company, as they reduced the number of shares outstanding.

Note 11. Income Taxes and Related Payments

APAM is subject to U.S. federal, state and local income taxation on APAM’s allocable portion of Holdings’ income as well as foreign income taxes payable by Holdings’ subsidiaries. APAM’s effective income tax rate was lower than the U.S. federal statutory rate of 21% primarily due to a rate benefit attributable to the fact that, for the nine months ended September 30, 2020, approximately 25% of Artisan Partners Holdings’ full year projected taxable earnings were attributable to other partners and not subject to corporate-level taxes. The effective tax rate was also lower than the statutory rate due to dividends paid on unvested share-based awards.

APAM’s effective tax rate was 18.1% and 7.3% for the nine months ended September 30, 2020 and 2019, respectively.

Components of the provision for income taxes consist of the following:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2020		2019		2020		2019
Current:
Federal	$	8,539	$	4,401	$	15,685	$	8,787
State and local	1,992		3,348		4,511		4,663
Foreign	97		111		261		339
Total	10,628		7,860		20,457		13,789
Deferred:
Federal	6,703		2,315		20,313		15,717
State and local	1,117		(17,530)		3,385		(15,935)
Total	7,820		(15,215)		23,698		(218)
Income tax expense (benefit)	$	18,448	$	(7,355)	$	44,155	$	13,571

In connection with the IPO, APAM entered into two tax receivable agreements (“TRAs”). The first TRA generally provides for the payment by APAM to a private equity fund (the “Pre-H&F Corp Merger Shareholder”) or its assignees of 85% of the applicable cash savings, if any, of U.S. federal, state and local income taxes that APAM actually realizes (or is deemed to realize in certain circumstances) as a result of (i) the tax attributes of the preferred units APAM acquired in the merger of a wholly-owned subsidiary of the Pre-H&F Corp Merger Shareholder into APAM in March 2013, (ii) net operating losses available as a result of the merger and (iii) tax benefits related to imputed interest.

The second TRA generally provides for the payment by APAM to current or former limited partners of Holdings or their assignees of 85% of the applicable cash savings, if any, of U.S. federal, state and local income taxes that APAM actually realizes (or is deemed to realize in certain circumstances) as a result of (i) certain tax attributes of their partnership units sold to APAM or exchanged (for shares of Class A common stock, convertible preferred stock or other consideration) and that are created as a result of such sales or exchanges and payments under the TRAs and (ii) tax benefits related to imputed interest. Under both agreements, APAM generally will retain the benefit of the remaining 15% of the applicable tax savings.

For purposes of the TRAs, cash savings of income taxes are calculated by comparing APAM’s actual income tax liability to the amount it would have been required to pay had it not been able to utilize any of the tax benefits subject to the TRAs, unless certain assumptions apply. The TRAs will continue in effect until all such tax benefits have been utilized or expired, unless APAM exercises its right to terminate the agreements or payments under the agreements are accelerated in the event that APAM materially breaches any of its material obligations under the agreements.

The actual increase in tax basis, as well as the amount and timing of any payments under these agreements, will vary depending upon a number of factors, including the timing of sales or exchanges by the holders of limited partnership units, the price of the Class A common stock at the time of such sales or exchanges, whether such sales or exchanges are taxable, the amount and timing of the taxable income APAM generates in the future and the tax rate then applicable and the portion of APAM’s payments under the TRAs constituting imputed interest or depreciable basis or amortizable basis.

Payments under the TRAs, if any, will be made pro rata among all TRA counterparties entitled to payments on an annual basis to the extent APAM has sufficient taxable income to utilize the increased depreciation and amortization charges and imputed interest deductions. Artisan expects to make one or more payments under the TRAs, to the extent they are required, prior to or within 125 days after APAM’s U.S. federal income tax return is filed for each fiscal year. Interest on the TRA payments will accrue at a rate equal to one-year LIBOR plus 100 basis points from the due date (without extension) of such tax return until such payments are made.

17

Amounts payable under tax receivable agreements are estimates which may be impacted by factors, including but not limited to, expected tax rates, projected taxable income, and projected ownership levels and are subject to change. Changes in the estimates of amounts payable under tax receivable agreements are recorded as non-operating income (loss) in the Unaudited Consolidated Statements of Operations.

The change in the Company’s deferred tax assets related to the tax benefits described above and the change in corresponding amounts payable under the TRAs for the nine months ended September 30, 2020 is summarized as follows:

	Deferred Tax Asset - Amortizable basis		Amounts payable under tax receivable agreements
December 31, 2019	$	408,140	$	375,324
2020 Follow-On Offering	21,424		18,211
2020 Holdings Common Unit Exchanges	23,094		19,630
Amortization	(26,504)		—
Payments under TRA	—		(26,943)
Change in estimate	(61)		(238)
September 30, 2020	$	426,093	$	385,984

Net deferred tax assets comprise the following:

	As of September 30, 2020		As of December 31, 2019
Deferred tax assets:
Amortizable basis (1)	$	426,093	$	408,140
Other (2)	32,605		27,757
Total deferred tax assets	458,698		435,897
Less: valuation allowance (3)	—		—
Net deferred tax assets	$	458,698	$	435,897
(1) Represents the unamortized step-up of tax basis and other tax attributes from the merger and partnership unit sales and exchanges described above. These future tax benefits are subject to the TRA agreements.
(2) Represents the net deferred tax assets associated with the merger described above and other miscellaneous deferred tax assets. These future tax benefits are not subject to the TRA agreements.
(3) Artisan assessed whether the deferred tax assets would be realizable and determined based on its history of taxable income that the benefits would more likely than not be realized. Accordingly, no valuation allowance is required.

Accounting standards establish a minimum threshold for recognizing, and a process for measuring, the benefits of income tax return positions in financial statements. The Company's gross liability for unrecognized tax benefits was $1.5 million and $2.0 million as of September 30, 2020 and December 31, 2019, respectively. The total amount of unrecognized tax benefits is not expected to significantly increase or decrease within the next twelve months.

The Company recognizes interest and penalties related to unrecognized tax benefits as a component of the income tax provision. Accrued interest on uncertain tax positions was $0.3 million as of September 30, 2020 and December 31, 2019. The gross unrecognized tax benefit is recorded within accounts payable, accrued expenses, and other in the Company’s Unaudited Condensed Consolidated Statements of Financial Condition.

In the normal course of business, Artisan is subject to examination by federal and certain state, local and foreign tax regulators. As of September 30, 2020, U.S. federal income tax returns filed for the years 2017 through 2019 are open and therefore subject to examination. State, local, and foreign income tax returns filed are generally subject to examination from 2016 to 2019.

Note 12. Earnings Per Share

Basic earnings per share is computed under the two-class method by dividing income available to Class A common stockholders by the weighted average number of Class A common shares outstanding during the period. Unvested restricted share-based awards are excluded from the number of Class A common shares outstanding for the basic earnings per share calculation because the shares have not yet been earned by employees. Income available to Class A common stockholders is computed by reducing net income attributable to APAM by earnings (both distributed and undistributed) allocated to participating securities, according to their respective rights to participate in those earnings. Except for certain performance share units, unvested share-based awards are participating securities because the awards include non-forfeitable dividend rights during the vesting period. Class B and Class C common shares do not share in profits of APAM and therefore are not reflected in the calculations.

Diluted earnings per share is computed under the more dilutive of the treasury stock method or the two-class method. The weighted average number of Class A common shares outstanding during the period is increased by the assumed conversion of nonparticipating unvested share-based awards into Class A common stock using the treasury stock method.

The computation of basic and diluted earnings per share for the three and nine months ended September 30, 2020 and 2019 were as follows:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
Basic and Diluted Earnings Per Share	2020		2019		2020		2019
Numerator:
Net income attributable to APAM	$	58,527	$	41,256	$	139,503	$	111,983
Less: Allocation to participating securities	6,006		4,494		16,944		16,521
Net income available to common stockholders	$	52,521	$	36,762	$	122,559	$	95,462
Denominator:
Basic weighted average shares outstanding	56,402,503		51,448,938		55,188,563		50,950,618
Dilutive effect of nonparticipating equity awards	5,769		—		1,923		—
Diluted weighted average shares outstanding	56,408,272		51,448,938		55,190,486		50,950,618
Earnings per share - Basic	$	0.93	$	0.71	$	2.22	$	1.87
Earnings per share - Diluted	$	0.93	$	0.71	$	2.22	$	1.87

Allocation to participating securities in the table above primarily represents dividends paid to holders of unvested restricted share-based awards, which reduces net income available to common stockholders.

The Holdings limited partnership units are anti-dilutive primarily due to the impact of public company expenses. Unvested restricted share-based awards with non-forfeitable dividend rights during the vesting period are considered participating securities and are therefore anti-dilutive. The following table summarizes the weighted-average shares outstanding that are excluded from the calculation of diluted earnings per share because their effect would have been anti-dilutive:

	For the Three Months Ended September 30,		For the Nine Months Ended September 30,
Anti-Dilutive Weighted Average Shares Outstanding	2020	2019	2020	2019
Holdings limited partnership units	17,177,313	21,594,086	18,308,766	21,958,470
Unvested restricted share-based awards	5,389,854	5,060,127	5,323,596	5,033,331
Total	22,567,167	26,654,213	23,632,362	26,991,801

Note 13. Indemnifications

In the normal course of business, APAM enters into agreements that include indemnities in favor of third parties. Holdings has also agreed to indemnify APAM as its general partner, Artisan Investment Corporation (“AIC”) as its former general partner, the directors and officers of APAM, the directors and officers of AIC as its former general partner, the members of its former Advisory Committee, and its partners, directors, officers, employees and agents. Holdings’ subsidiaries may also have similar agreements to indemnify their respective general partner(s), directors, officers, directors and officers of their general partner(s), partners, members, employees, and agents. The Company’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against us that have not yet occurred. APAM maintains insurance policies that may provide coverage against certain claims under these indemnities.

19

Note 14. Related Party Transactions

Several of the current executive officers and directors of APAM or entities associated with those individuals, are limited partners of Holdings. As a result, certain transactions (such as TRA payments) between Artisan and the limited partners of Holdings are considered to be related party transactions with respect to these persons.

Affiliate transactions—Artisan Funds

Artisan has an agreement to serve as the investment adviser to Artisan Funds, with which certain Artisan employees are affiliated. Under the terms of the agreement, which generally is reviewed and continued by the board of directors of Artisan Funds annually, a fee is paid to Artisan based on an annual percentage of the average daily net assets of each Artisan Fund ranging from 0.625% to 1.05%. Artisan has contractually agreed to waive its management fees or reimburse for expenses incurred to the extent necessary to limit annualized ordinary operating expenses incurred by certain of the Artisan Funds to not more than a fixed percentage (ranging from 0.88% to 1.50%) of a fund’s average daily net assets. In addition, Artisan may voluntarily waive fees or reimburse any of the Artisan Funds for other expenses. The officers and directors of Artisan Funds who are affiliated with Artisan receive no compensation from the funds.

Investment advisory fees for managing Artisan Funds and amounts waived or reimbursed by Artisan for fees and expenses (including management fees) are as follows:

Artisan reimburses each sub-fund of Artisan Global Funds to the extent that sub-fund’s annual expenses, not including Artisan’s fee, exceed certain levels, which range from 0.10% to 0.20%. In addition, Artisan may voluntarily waive fees or reimburse any of the Artisan Global Funds for other expenses. The directors of Artisan Global Funds who are also employees of Artisan receive no compensation from the funds.

Investment advisory fees for managing Artisan Global Funds and amounts reimbursed to Artisan Global Funds by Artisan are as follows:

Affiliate transactions—Artisan Private Funds

Pursuant to written agreements, Artisan serves as the investment manager, and acts as the general partner, for certain Artisan Private Funds. Under the terms of these agreements, Artisan earns a management fee and for certain funds is entitled to receive either an allocation of profits or a performance-based fee. In addition, for a period of time following the formation of each private fund, Artisan has agreed to reimburse the fund to the extent that expenses, excluding Artisan’s management fee, performance fee and transaction related costs, exceed certain levels, which range from 0.10% to 1.00% per annum of the net assets of the fund. Artisan may also voluntarily waive fees or reimburse the funds for other expenses.

Artisan and certain related parties, including employees, officers and members of the Company’s board have invested in one or more of the funds and currently do not pay a management fee, performance fee or incentive allocation.

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

Overview

We are an investment management firm focused on providing high-value added, active investment strategies to sophisticated clients globally. As of September 30, 2020, our nine autonomous investment teams managed a total of 18 investment strategies across multiple asset classes and investment styles. Over our firm’s history, we have created new investment strategies that can use a broad array of securities, instruments, and techniques (which we call degrees of freedom) to differentiate returns and manage risk. On October 1, 2020, we launched our 19th strategy, the International Small Cap Value strategy.

We focus our distribution efforts on sophisticated investors and asset allocators, including institutions and intermediaries that operate with institutional-like decision-making processes. We offer our investment strategies to clients and investors through multiple investment vehicles, including separate accounts and different types of pooled vehicles. As of September 30, 2020, approximately 79% of our assets under management were managed for clients and investors domiciled in the U.S. and 21% of our assets under management were managed for clients and investors domiciled outside of the U.S.

As a high-value added investment manager we expect that long-term investment performance will be the primary driver of our long-term business and financial results. If we maintain and evolve existing investment strategies and launch new investment strategies that meet the needs of and generate attractive outcomes for sophisticated asset allocators, we believe that we will continue to generate strong business and financial results.

Over shorter time periods, changes in our business and financial results are largely driven by market conditions and fluctuations in our assets under management that may not necessarily be the result of our long-term investment performance or the long-term demand for our strategies. For this reason, we expect that our business and financial results will be lumpy over time.

We strive to maintain a financial model that is transparent and predictable. Currently, we derive nearly all of our revenues from investment management fees, most of which are based on a specified percentage of clients’ average assets under management. A majority of our expenses, including most of our compensation expense, vary directly with changes in our revenues. We invest thoughtfully to support our investment teams and future growth, while also paying out to shareholders and partners a majority of the cash that we generate from operations through distributions and dividends.

Business and financial highlights for the quarter included:

•Beini Zhou and Anand Vasagiri joined the Artisan International Value team to launch a new International Small Cap Value strategy. Separately, Tiffany Hsiao and Yuanyuan Ji joined the Artisan Global Equity team to design and launch a new strategy focused on post-venture firms in greater China.

•During the three months ended September 30, 2020, our assets under management increased to $134.3 billion, an increase of $13.7 billion, or 11%, compared to $120.6 billion at June 30, 2020, as a result of $11.6 billion in positive investment returns and $2.1 billion of net client cash inflows.

•Average assets under management for the three months ended September 30, 2020 were $131.0 billion, an increase of 16% from the average of $113.0 billion for the three months ended September 30, 2019, and an increase of 20% from the average of $109.3 billion for the three months ended June 30, 2020.

•We earned $232.7 million in revenue for the three months ended September 30, 2020, an increase of 15% from revenues of $202.9 million for the three months ended September 30, 2019.

•Our operating margin was 41.8% for the three months ended September 30, 2020, compared to 37.2% for the three months ended September 30, 2019.

•We generated $0.93 of earnings per basic and diluted share and $0.90 of adjusted EPS.

•We declared and distributed dividends of $0.67 per share of Class A common stock during the three months ended September 30, 2020.

•We declared, effective October 27, 2020, a quarterly dividend of $0.83 per share of Class A common stock.

COVID-19 Pandemic

The COVID-19 pandemic contributed to significant volatility in global markets and corresponding fluctuations in the valuation of our assets under management. Because most of the revenue we earn is based on the market value of our assets under management, fluctuations in global markets impact our revenues and earnings. Our assets under management declined from $125.4 billion on February 19, 2020 to $95.2 billion on March 31, 2020, and have subsequently rebounded to $134.3 billion as of September 30, 2020.

The COVID-19 pandemic continues to impact the manner in which we operate. As of the date of this filing, the majority of our employees are working from home and our employees have significantly reduced business travel. Additionally, many third-party vendors on whom we rely for certain critical functions are also operating in remote environments. Given the continued uncertainty surrounding the COVID-19 pandemic, it is difficult to predict how long such remote working conditions and travel restrictions will last. We expect most operating costs to return to pre-COVID-19 levels when employees return to the office and resume business travel.

We believe we are operating well under these circumstances, benefiting from the flexible and highly mobile operating environment we have built over 25 years. However, market volatility, as well as changes in our operations and those of our key vendors, may result in increased client redemptions; inefficiencies, delays and decreased communication; and an increase in the number and significance of operational and trade errors. In addition, we do not know what, if any, longer-term impact the current operating circumstances (and/or the extension of them) will have on our business and results.

Given the fluidity of the COVID-19 pandemic situation, our executive team is meeting regularly to ensure Artisan is well-positioned to quickly adjust and react as circumstances warrant, and is providing frequent communications internally with and among our associates and our board of directors—and externally with clients, prospects, consultants and shareholders.

Organizational Structure

Organizational Structure

Our operations are conducted through Artisan Partners Holdings (“Holdings”) and its subsidiaries. On March 12, 2013, Artisan Partners Asset Management Inc. (“APAM”) and Artisan Partners Holdings LP completed a series of transactions (“the IPO Reorganization”) to reorganize their capital structures in connection with the initial public offering (“IPO”) of APAM’s Class A common stock. The IPO Reorganization and IPO were completed on March 12, 2013. The IPO Reorganization was designed to create a capital structure that preserves our ability to conduct our business through Holdings, while permitting us to raise additional capital and provide access to liquidity through a public company.

Our employees and other limited partners of Holdings held approximately 22% of the equity interests in Holdings as of September 30, 2020. As a result, our results reflect that significant noncontrolling interest.

We operate our business in a single segment.

2020 Follow-On Offering and Holdings Unit Exchanges

On February 24, 2020, APAM completed an offering of 1,802,326 shares of Class A common stock and utilized all of the proceeds to purchase an aggregate of 1,802,326 common units from certain limited partners of Holdings. In connection with the offering, APAM received 1,802,326 GP units of Holdings.

During the nine months ended September 30, 2020, certain limited partners of Holdings exchanged 2,420,124 common units (along with a corresponding number of shares of Class B or Class C common stock of APAM) for 2,420,124 shares of Class A common stock. In connection with the exchanges, APAM received 2,420,124 GP units of Holdings.

APAM’s equity ownership interest in Holdings increased from 73% at December 31, 2019 to 78% at September 30, 2020, as a result of these transactions and other equity transactions during the period.

Key Performance Indicators

When we review our business and financial performance we consider, among other things, the following:

	For the Three Months Ended September 30,						For the Nine Months Ended September 30,
	2020			2019			2020			2019

Operating margin	41.8		%	37.2		%	38.3		%	34.6		%
(1) We compute average assets under management by averaging day-end assets under management for the applicable period.
(2) We compute our weighted average management fee by dividing annualized investment management fees (which excludes performance fees) by average assets under management for the applicable period. The weighted average management fee for prior periods have been recast to exclude performance fee revenue.

Investment advisory fees and assets under management within our consolidated investment products are excluded from the weighted average fee calculations and from total revenues, since any such revenues are eliminated upon consolidation. Assets under management within Artisan Private Funds are included in the reported firm-wide, separate account, and institutional assets under management figures reported below.

Assets Under Management and Investment Performance

Changes to our operating results from one period to another are primarily caused by changes in the amount of our assets under management. Changes in the relative composition of our assets under management among our investment strategies and vehicles and the effective fee rates on our products also impact our operating results.

The amount and composition of our assets under management are, and will continue to be, influenced by a variety of factors including, among others:

•investment performance, including fluctuations in both the financial markets and foreign currency exchange rates and the quality of our investment decisions;

•flows of client assets into and out of our various strategies and investment vehicles;

•our decision to close strategies or limit the growth of assets in a strategy or a vehicle when we believe it is in the best interest of our clients; as well as our decision to re-open strategies, in part or entirely;

•our ability to attract and retain qualified investment, management, and marketing and client service professionals;

•industry trends towards products, strategies, vehicles, or services that we do not offer;

•competitive conditions in the investment management and broader financial services sectors; and

•investor sentiment and confidence.

(1) Includes the impact of translating the value of assets under management denominated in non-USD currencies into U.S. dollars. The impact was immaterial for the periods presented.

During the quarter, our AUM increased by $13.7 billion due to $11.6 billion in positive investment returns and $2.1 billion of net client cash inflows. 10 of our 18 investment strategies had net inflows, totaling $3.6 billion. Our eight strategies with inception dates beginning in 2014 or later had $2.5 billion in net inflows. We expect those strategies as a group to continue to experience net inflows.

Our Non-US Growth, International Value and US Mid-Cap Value strategies had a total of $1.3 billion of net outflows during the quarter, which partially offset the net inflows described above.

Over the long-term, we expect to generate the majority of our AUM growth through investment returns, which has been our historical experience.

We monitor the availability of attractive investment opportunities relative to the amount of assets we manage in each of our investment strategies. When appropriate, we will close a strategy to new investors or otherwise take action to slow or restrict its growth, even though our aggregate assets under management may be negatively impacted in the short term. We may also re-open a strategy, widely or selectively, to fill available capacity or manage the diversification of our client base in that strategy. We believe that management of our investment capacity protects our ability to manage assets successfully, which protects the interests of our clients and, in the long term, protects our ability to retain client assets and maintain our profit margins.

As of the date of this filing, all our strategies are open to new investors and client relationships. Our US Small-Cap Growth and Global Opportunities strategies have limited availability to most new client relationships.

When we close or otherwise restrict the growth of a strategy, we typically continue to allow additional investments in the strategy by existing clients and certain related entities. We may also permit new investments by other eligible investors in our discretion. As a result, during a given period we may have net client cash inflows in a closed strategy. However, when a strategy is closed or its growth is restricted we expect there to be periods of net client cash outflows.

25

In November 2020 we expect the Artisan Funds will make their annual income and capital gain distributions. Based on our current estimates and assumptions, we expect this year's distributions to result in approximately $450 million of net client cash outflows from investors who choose not to reinvest their dividends. In November 2019 those distributions resulted in approximately $470 million of net client cash outflows. The November 2020 distribution (estimates of which we expect Artisan funds will disclose in advance of the record date) may cause increased mutual fund redemptions.

The table on the following page sets forth the average annual total returns for each composite (gross of fees) and its respective broad-based benchmark (and style benchmark, if applicable) over a multi-horizon time period as of September 30, 2020. Returns for periods less than one year are not annualized.

We measure investment performance based upon the results of our “composites”, which represent the aggregate performance of all discretionary client accounts, including pooled investment vehicles, invested in the same strategy except those accounts with respect to which we believe client-imposed investment restrictions may have a material impact on portfolio construction and those accounts managed in a currency other than U.S. dollars. The results of these excluded accounts, which represented approximately 10% of our assets under management at September 30, 2020, are maintained in separate composites the results of which are not included below.

(1) Value-added is the amount in basis points by which the average annual gross composite return of each of our strategies has outperformed or underperformed the benchmark most commonly used by our separate account clients to compare the performance of the relevant strategy. The benchmark most commonly used by clients in the U.S. Mid-Cap Growth, U.S. Small Cap Growth, Value Equity, and U.S. Mid-Cap Value strategies is the style benchmark and for all other strategies is the broad market benchmark. Reporting on this metric prior to September 30, 2020, compared all composite performance to the broad benchmark. Value-added for periods less than one year is not annualized. The Artisan High Income Strategy may hold loans and other security types that may not be included in the ICE BofA U.S. High Yield Master II Total Return Index. At times, this causes material differences in relative performance. The Antero Peak Strategy's investments in initial public offerings (IPOs) made a material contribution to performance. IPO investments may contribute significantly to a small portfolio’s return, an effect that will generally decrease as assets grow. IPO investments may be unavailable in the future.

(2) Other Assets Under Management includes AUM managed by the Credit Team in the Credit Opportunities strategy and by the Antero Peak Group in the Antero Peak Hedge strategy, respectively. Strategy specific information has been omitted.

(3) Effective October 1, 2020, the Thematic investment team was renamed Antero Peak Group. The team's investment strategies and investment products were also renamed effective October 1, 2020.

The goal of our marketing, distribution and client services efforts is to establish and maintain a client base that is diversified by investment strategy, investment vehicle and distribution channel.

Investment Advisory Revenues

Essentially all of our revenues consist of fees earned from managing clients’ assets. Our investment advisory fees, which are comprised of management fees and performance fees, fluctuate based on a number of factors, including the total value of our assets under management, the composition of assets under management among investment vehicles and our investment strategies, changes in the investment management fee rates on our products, the extent to which we enter into fee arrangements that differ from our standard fee schedules, which can be affected by custom and the competitive landscape in the relevant market, and, for the accounts on which we earn performance-based fees, the investment performance of those accounts.

Approximately 3% of our $134.3 billion of assets under management as of September 30, 2020 have performance fee billing arrangements. While performance fees may be earned and recognized in each quarter of the year, we expect the majority of our performance fees in 2020 to be recognized during the June quarter. Performance fees of $0.3 million were recognized in the three months ended September 30, 2020, compared to $0.2 million in the three months ended September 30, 2019.

The increase in revenues of $29.8 million, or 15%, for the three months ended September 30, 2020, compared to the three months ended September 30, 2019, was driven primarily by a $17.9 billion, or 16%, increase in our average assets under management. The weighted average management fee, which excludes performance fees, was 70.7 basis points for the three months ended September 30, 2020 compared to 71.2 basis points for the three months ended September 30, 2019.

The following table sets forth the investment advisory fees and weighted average management fee earned by investment vehicle. The weighted average management fee for Artisan Funds and Artisan Global Funds reflects the additional services we provide to these pooled vehicles.

(1) We compute our weighted average management fee by dividing annualized management fees (which excludes performance fees) by average assets under management for the applicable period. The weighted average management fee for prior periods have been recast to exclude performance fee revenue.

Separate account assets under management consist of the assets we manage in or through vehicles other than Artisan Funds or Artisan Global Funds, including assets we manage in traditional separate accounts, as well as assets we manage in Artisan-branded collective investment trusts, in funds (both public and private) that we sub-advise, and in our own privately offered funds.

Operating Expenses

Operating expenses increased $8.1 million for the three months ended September 30, 2020 compared to the three months ended September 30, 2019, primarily as a result of higher incentive compensation expense related to increased revenues, partially offset by a decrease in travel expenses in response to the COVID-19 pandemic.

Compensation and Benefits

	For the Three Months Ended September 30,				Period-to-Period
	2020		2019		$		%
	(unaudited; in millions)
Salaries, incentive compensation and benefits(1)	$	99.6	$	89.9	$	9.7	11	%

Total compensation and benefits	$	108.7	$	99.8	$	8.9	9	%
(1) Excluding restricted share-based award compensation expense

The increase in salaries, incentive compensation, and benefits was driven primarily by a $8.8 million increase in incentive compensation paid to our investment and marketing professionals as a result of the increase in revenue.

Restricted share-based award compensation expense decreased $0.8 million, as the awards that became fully amortized during 2019 and 2020 had a higher value than the awards granted in 2019 and 2020. Restricted share-based award compensation expense for all outstanding awards is expected to be approximately $9 million per quarter in 2020.

Total salaries, incentive compensation and benefits was 47% and 49% of our revenues for the three months ended September 30, 2020, and 2019, respectively.

Other operating expenses

Other operating expenses decreased $0.8 million for the three months ended September 30, 2020 compared to the three months ended September 30, 2019, primarily due to a $2.1 million decrease in travel and entertainment expenses resulting from the COVID-19 pandemic, partially offset by an occupancy charge related to unused office space.

Non-Operating Income (Expense)

Non-operating income (expense) consisted of the following:

	For the Three Months Ended September 30,				Period-to-Period
	2020		2019		$		%
	(unaudited; in millions)
Interest expense	$	(2.7)	$	(2.7)	$	—	—	%
Net investment gain (loss) of consolidated investment products	7.8		0.7		7.1		1,014	%
Net gain (loss) on the tax receivable agreements	0.2		(19.6)		19.8		(101)	%
Other investment gain (loss)	0.6		1.0		(0.4)		(40)	%
Total non-operating income (expense)	$	5.9	$	(20.6)	$	26.5	(129)	%

Non-operating income (expense) for the three months ended September 30, 2020 includes a $0.2 million gain relating to a change in estimate of the payment obligation under the tax receivable agreements, compared to a $19.6 million loss for the three months ended September 30, 2019. The effect of changes in that estimate after the date of an exchange or sale is included in net income. The change in estimate in 2019 was due to the remeasurement of deferred tax assets relating to an increase in estimated state income tax expense.

Provision for Income Taxes

The provision for income taxes primarily represents APAM’s U.S. federal, state and local income taxes on its allocable portion of Holdings’ income, as well as foreign income taxes payable by Holdings’ subsidiaries. APAM’s effective income tax rate for the three months ended September 30, 2020 and 2019 was 17.9% and (13.4)%, respectively. Several factors contribute to the effective tax rate, including a rate benefit attributable to the fact that approximately 25% and 31% of Holdings’ full year projected taxable earnings were not subject to corporate-level taxes for the three months ended September 30, 2020 and 2019, respectively. Thus, income before income taxes includes amounts that are attributable to noncontrolling interests and not taxable to APAM and its subsidiaries, which reduces the effective tax rate. As APAM’s equity ownership in Holdings increases, the effective tax rate will likewise increase as more income will be subject to corporate-level taxes. The effective tax rate was favorably impacted in both periods due to tax deductible dividends paid on unvested restricted share-based awards.

During the three months ended September 30, 2019, the tax rate used to measure APAM’s deferred tax assets increased, which resulted in an increase to our deferred tax assets of $23.0 million with a corresponding decrease to the provision for income taxes.

Earnings Per Share

Weighted average basic and diluted shares of Class A common stock outstanding were higher for the three months ended September 30, 2020, compared to the three months ended September 30, 2019, as a result of stock offerings, unit exchanges, and equity award grants. See Note 12, “Earnings Per Share” in the Notes to the Unaudited Consolidated Financial Statements for further discussion of earnings per share.

Investment Advisory Revenues

The increase in revenues of $47.9 million, or 8%, for the nine months ended September 30, 2020, compared to the nine months ended September 30, 2019, was driven primarily by an $8.7 billion, or 8%, increase in our average assets under management and an increase in performance fee revenue. The weighted average management fee, which excludes performance fees, was 71.0 basis points for the nine months ended September 30, 2020 compared to 71.7 basis points for the nine months ended September 30, 2019. Performance fee revenue was $11.2 million and $4.6 million for the nine months ended September 30, 2020 and 2019, respectively.

The following table sets forth the investment advisory fees and weighted average management fee earned by investment vehicle. The weighted average management fee for Artisan Funds and Artisan Global Funds reflects the additional services we provide to these pooled vehicles.

Operating Expenses

Operating expenses increased $7.2 million for the nine months ended September 30, 2020, compared to the nine months ended September 30, 2019, primarily as a result of higher incentive compensation expense related to increased revenues and higher salary and benefits expenses on an increased number of employees. The increases were partially offset by lower equity based compensation expense and a decrease in travel expenses.

Compensation and Benefits

	For the Nine Months Ended September 30,				Period-to-Period
	2020		2019		$		%

Total compensation and benefits	$	315.6	$	300.6	$	15.0	5	%
(1) Excluding share-based compensation

The increase in salaries, incentive compensation, and benefits was driven primarily by a $16.7 million increase in incentive compensation paid to our investment and marketing professionals as a result of the increase in revenue, as well as compensation expense related to additional full-time employees in 2020.

Restricted share-based award compensation expense decreased $6.0 million as the awards that became fully amortized during 2019 and 2020 had a higher value than the awards granted in 2019 and 2020.

Total salaries, incentive compensation and benefits was 49% and 51% of our revenues for the nine months ended September 30, 2020, and 2019, respectively.

Other operating expenses

Other operating expenses decreased $7.8 million for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019, primarily due to a $5.3 million decrease in travel and entertainment expenses resulting from the COVID-19 pandemic. Occupancy expense decreased $1.4 million primarily due to higher charges recorded in 2019 related to unused office space.

Non-Operating Income (Expense)

Non-operating income (expense) consisted of the following:

	For the Nine Months Ended September 30,				Period-to-Period
	2020		2019		$		%
	(unaudited; in millions)
Interest expense	$	(8.1)	$	(8.3)	$	0.2	(2)	%

Total non-operating income (expense)	$	(0.6)	$	(18.5)	$	17.9	(97)	%

Non-operating income (expense) for the nine months ended September 30, 2020 includes a $0.2 million gain relating to a change in estimate of the payment obligation under the tax receivable agreements, compared to a $19.6 million loss for the nine months ended September 30, 2019. The effect of changes in that estimate after the date of an exchange or sale is included in net income. The change in estimate in 2019 was due to the remeasurement of deferred tax assets relating to an increase in estimated state income tax expense.

Provision for Income Taxes

The provision for income taxes primarily represents APAM’s U.S. federal, state and local income taxes on its allocable portion of Holdings’ income, as well as foreign income taxes payable by Holdings’ subsidiaries. APAM’s effective income tax rate for the nine months ended September 30, 2020 and 2019 was 18.1% and 7.3%, respectively.

35

Several factors contribute to the effective tax rate, including a rate benefit attributable to the fact that approximately 25% and 31% of Holdings’ full year projected taxable earnings were not subject to corporate-level taxes for the nine months ended September 30, 2020 and 2019, respectively. Thus, income before income taxes includes amounts that are attributable to noncontrolling interests and not taxable to APAM and its subsidiaries, which reduces the effective tax rate. As APAM’s equity ownership in Holdings increases, the effective tax rate will likewise increase as more income will be subject to corporate-level taxes. The effective tax rate was favorably impacted in both periods due to tax deductible dividends paid on unvested restricted share-based awards.

During the nine months ended September 30, 2019, the tax rate used to measure APAM’s deferred tax assets increased which resulted in an increase to our deferred tax assets of $23.0 million with a corresponding decrease to the provision for income taxes.

Earnings Per Share

Weighted average basic and diluted shares of Class A common stock outstanding were higher for the nine months ended September 30, 2020, compared to the nine months ended September 30, 2019, as a result of stock offerings, unit exchanges, and equity award grants. See Note 12, “Earnings Per Share” in the Notes to the Unaudited Consolidated Financial Statements for further discussion of earnings per share.

Supplemental Non-GAAP Financial Information

Our management uses non-GAAP measures (referred to as “adjusted” measures) of net income to evaluate the profitability and efficiency of the underlying operations of our business and as a factor when considering net income available for distributions and dividends. These adjusted measures remove the impact of (1) net gain (loss) on the tax receivable agreements (if any) and (2) net investment gain (loss) of investment products. These adjustments also remove the non-operational complexities of our structure by adding back noncontrolling interests and assuming all income of Artisan Partners Holdings is allocated to APAM. Management believes these non-GAAP measures provide more meaningful information to analyze our profitability and efficiency between periods and over time. We have included these non-GAAP measures to provide investors with the same financial metrics used by management to manage the company.

Non-GAAP measures should be considered in addition to, and not as a substitute for, financial measures prepared in accordance with GAAP. Our non-GAAP measures may differ from similar measures used by other companies, even if similar terms are used to identify such measures. Our non-GAAP measures are as follows:

•Adjusted net income represents net income excluding the impact of (1) net gain (loss) on the tax receivable agreements (if any) and (2) net investment gain (loss) of investment products. Adjusted net income also reflects income taxes assuming the vesting of all unvested Class A share-based awards and as if all outstanding limited partnership units of Artisan Partners Holdings had been exchanged for Class A common stock of APAM on a one-for-one basis. Assuming full vesting and exchange, all income of Artisan Partners Holdings is treated as if it were allocated to APAM, and the adjusted provision for income taxes represents an estimate of income tax expense at an effective rate reflecting APAM's current federal, state, and local income statutory tax rates. The adjusted tax rate was 24.5% and 24.1% for the 2020 and 2019 periods presented, respectively. The year-to-date impact of the change in the 2019 adjusted tax rate during the three months ended September 30, 2019 from 23.5% to 24.1% is reflected in adjusted net income for the three months ended September 30, 2019 (which results in an adjusted effective tax rate of 25.1% for that quarter).

•Adjusted net income per adjusted share is calculated by dividing adjusted net income by adjusted shares. The number of adjusted shares is derived by assuming the vesting of all unvested Class A share-based awards and the exchange of all outstanding limited partnership units of Artisan Partners Holdings for Class A common stock of APAM on a one-for-one basis.

•Adjusted EBITDA represents adjusted net income before interest expense, income taxes, depreciation and amortization expense.

Net gain (loss) on the tax receivable agreements represents the income (expense) associated with the change in estimate of amounts payable under the tax receivable agreements entered into in connection with APAM’s initial public offering and related reorganization.

Net investment gain (loss) of investment products represents the non-operating income (expense) related to the Company’s seed investments, in both consolidated investment products and nonconsolidated investment products. Excluding these non-operating market gains or losses on seed investments provides greater transparency to evaluate the profitability and efficiency of the underlying operations of the business.

Liquidity and Capital Resources

Our working capital needs, including accrued incentive compensation payments, have been and are expected to be met primarily through cash generated by our operations. The assets and liabilities of consolidated investment products attributable to third-party investors do not impact our liquidity and capital resources. We have no right to the benefits from, nor do we bear the risks associated with, the assets and liabilities of consolidated investment products, beyond our direct equity investment and any management fees and performance fees earned. Accordingly, assets and liabilities of consolidated investment products attributable to third party investors are excluded from the amounts and discussions below. The following table shows our liquidity position as of September 30, 2020, and December 31, 2019:

	September 30, 2020		December 31, 2019
	(unaudited; in millions)
Cash and cash equivalents	$	200.4	$	134.6
Accounts receivable	$	98.4	$	81.9
Seed investments(1)	$	58.0	$	57.8
Undrawn commitment on revolving credit facility	$	100.0	$	100.0
(1) Seed investments include Artisan's direct equity investments in consolidated and nonconsolidated Artisan-sponsored investment products.

We manage our cash balances in order to fund our day-to-day operations. Accounts receivable primarily represent investment advisory fees that have been earned, but not yet received from our clients. We perform a review of our receivables on a monthly basis to assess collectability. As of September 30, 2020, none of our receivables were considered uncollectable.

We utilize capital to make seed investments in Artisan-sponsored investment products to support the development of new investment strategies and vehicles. As of September 30, 2020, the balance of all seed investments, including investments in consolidated investment products, was $58.0 million. The seed investments are generally redeemable at our discretion.

We have $200 million in unsecured notes outstanding and a $100 million revolving credit facility with a five-year term ending August 2022. The notes are comprised of three series, Series C, Series D, and Series E, each with a balloon payment at maturity. The $100 million revolving credit facility was unused as of and for the nine months ended September 30, 2020.

The fixed interest rate on each series of unsecured notes is subject to a 100 basis point increase in the event Holdings receives a below-investment grade rating and any such increase will continue to apply until an investment grade rating is received.

These borrowings contain various covenants. Our failure to comply with any of the covenants could result in an event of default under the agreements, giving our lenders the ability to accelerate repayment of our obligations. We were in compliance with all debt covenants as of September 30, 2020.

Distributions and Dividends

Artisan Partners Holdings’ distributions, including distributions to APAM for the three and nine months ended September 30, 2020 and 2019, were as follows:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2020		2019		2020		2019
	(unaudited, in millions)
Holdings Partnership Distributions to Limited Partners	$	20.9	$	21.9	$	60.2	$	70.2
Holdings Partnership Distributions to APAM	70.0		53.4		181.4		166.3
Total Holdings Partnership Distributions	$	90.9	$	75.3	$	241.6	$	236.5

On October 27, 2020, we, acting as the general partner of Artisan Partners Holdings, declared a distribution of $40.6 million, payable by Artisan Partners Holdings to holders of its partnership units, including us.

APAM declared and paid the following dividends per share during the three and nine months ended September 30, 2020 and 2019:

Type of Dividend	Class of Stock	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
		2020		2019		2020		2019
Quarterly	Class A Common	$	0.67	$	0.60	$	1.96	$	1.71
Special Annual	Class A Common	$	—	$	—	$	0.60	$	1.03

Our board of directors declared, effective October 27, 2020, a variable quarterly dividend of $0.83 per share of Class A common stock with respect to the September quarter of 2020, payable on November 30, 2020 to shareholders of record as of the close of business on November 16, 2020. The variable quarterly dividend represents approximately 80% of the cash generated in the September quarter of 2020 and a pro-rata portion of 2020 tax savings related to our tax receivable agreements.

Subject to board approval each quarter, we currently expect to pay a quarterly dividend of approximately 80% of the cash the Company generates each quarter. After the end of the year, our board will consider paying a special dividend after determining the amount of cash needed for general corporate purposes and investments in growth and strategic initiatives. Although we expect to pay dividends according to our dividend policy, we may not pay dividends according to our policy or at all.

Tax Receivable Agreements (“TRAs”)

In addition to funding our normal operations, we will be required to fund amounts payable under the TRAs that we entered into in connection with the IPO, which resulted in the recognition of a $386.0 million liability as of September 30, 2020. The liability generally represents 85% of the tax benefits APAM expects to realize as a result of the merger of an entity into APAM as part of the IPO Reorganization, our purchase of partnership units from limited partners of Holdings and the exchange of partnership units (for shares of Class A common stock or other consideration). The estimated liability assumes no material changes in the relevant tax law and that APAM earns sufficient taxable income to realize all tax benefits subject to the TRAs. An increase or decrease in future tax rates will increase or decrease, respectively, the expected tax benefits APAM would realize and the amounts payable under the TRAs. Changes in the estimate of expected tax benefits APAM would realize and the amounts payable under the TRAs as a result of change in tax rates have been and will be recorded in net income.

The liability will increase upon future purchases or exchanges of limited partnership units with the increase representing amounts payable under the TRAs equal to 85% of the estimated future tax benefits, if any, resulting from such purchases or exchanges. We intend to fund the payment of amounts due under the TRAs out of the reduced tax payments that APAM realizes in respect of the tax attributes to which the TRAs relate.

The actual increase in tax basis, as well as the amount and timing of any payments under these agreements, will vary depending upon a number of factors, including the timing of sales or exchanges by the holders of limited partnership units, the price of the Class A common stock at the time of such sales or exchanges, whether such sales or exchanges are taxable, the amount and timing of the taxable income APAM generates in the future and the tax rate then applicable and the portion of APAM’s payments under the TRAs constituting imputed interest or depreciable basis or amortizable basis. In certain cases, payments under the TRAs may be accelerated and/or significantly exceed the actual benefits we realize in respect of the tax attributes subject to the TRAs. In such cases, we intend to fund those payments with cash on hand, although we may have to borrow funds depending on the amount and timing of the payments. During the nine months ended September 30, 2020, we made payments of $26.9 million related to the TRAs. We do not intend to make any additional TRA payments in 2020. In 2021, we expect to make payments of approximately $30 million related to the TRAs.

Cash Flows

	For the Nine Months Ended September 30,
	2020		2019
	(unaudited; in millions)
Cash, cash equivalents and restricted cash as of January 1	$	144.3	$	175.5
Net cash provided by operating activities	298.7		261.6
Net cash provided by (used in) investing activities	16.2		(16.7)
Net cash used in financing activities	(228.3)		(246.5)
Cash, cash equivalents and restricted cash as of September 30	$	230.9	$	173.9

Net cash provided by operating activities increased $37.1 million for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019, primarily due to an increase in operating income resulting from higher AUM and revenues. For the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019, our operating income, excluding share-based related compensation expense, increased $34.7 million.

Investing activities consist primarily of acquiring and selling property and equipment, leasehold improvements and the purchase and sale of investment securities. Net cash provided by investment activities increased $32.9 million for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019, primarily due to a $18.0 million increase in net proceeds from the sale of investment securities and a $14.9 million decrease in the acquisition of property and equipment and leasehold improvements.

Financing activities consist primarily of partnership distributions to noncontrolling interests, dividend payments to holders of our Class A common stock, proceeds from the issuance of Class A common stock in follow-on offerings, payments to purchase Holdings partnership units, and payments of amounts owed under the tax receivable agreements. Net cash used by financing activities decreased $18.2 million for the nine months ended September 30, 2020 compared to the nine months ended September 30, 2019, primarily due to a $9.9 million decrease in distributions to limited partners and a $12.4 million increase in contributions from noncontrolling interests in our consolidated investment products, partially offset by a $2.5 million increase in taxes paid related to employee net share settlement and a $1.9 million increase in payments of amounts owed under the TRAs.

Certain Contractual Obligations

As of September 30, 2020, there have been no material changes to our contractual obligations outside the ordinary course of business from those listed in the “Certain Contractual Obligations” table and related notes to the table in our Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on February 18, 2020, except for the changes in the TRA liability during the year.

As previously discussed in this report, the TRA liability increased from $375.3 million at December 31, 2019 to $386.0 million at September 30, 2020. Amounts payable under the TRAs will increase upon exchanges of Holdings units for our Class A common stock or sales of Holdings units to us, with the increase representing 85% of the estimated future tax benefits, if any, resulting from such exchanges or sales and decrease when payments are made. The actual amount and timing of payments associated with our existing payable under the TRAs or future exchanges or sales, and associated tax benefits, will vary depending upon a number of factors as described under “Liquidity and Capital Resources.” As a result, the timing of payments by period is currently unknown. During the nine months ended September 30, 2020, we made payments of $26.9 million related to the TRAs. We do not intend to make any additional TRA payments in 2020. In 2021, we expect to make payments of approximately $30 million related to the TRAs.

Off-Balance Sheet Arrangements

As of September 30, 2020, we did not have any off-balance sheet arrangements that have, or are reasonably likely to have, a material current or future effect on our financial condition, results of operations, liquidity or capital resources.

40

Critical Accounting Policies and Estimates

There have been no updates to our critical accounting policies from those disclosed in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Form 10-K for the year ended December 31, 2019.

New or Revised Accounting Standards

See Part I, Item 1, Unaudited Consolidated Financial Statements - Note 2, “Summary of Significant Accounting Policies.”

Item 3. Qualitative and Quantitative Disclosures Regarding Market Risk

There have been no material changes in our Quantitative and Qualitative Disclosures Regarding Market Risk from those previously reported in our Form 10-K for the year ended December 31, 2019.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act, that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive and principal financial officers, as appropriate, to allow for timely decisions regarding required disclosure.

Our management, including our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) at September 30, 2020. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting

There have been no changes in internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended September 30, 2020, that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

41

Part II — Other Information

Item 1. Legal Proceedings

In the normal course of business, we may be subject to various legal and administrative proceedings. Currently, there are no legal or administrative proceedings that management believes may have a material effect on our consolidated financial position, cash flows or results of operations.

Item 1A. Risk Factors

The outbreak of COVID-19, and the reaction thereto, has negatively affected the global economy and has disrupted our normal business operations.

The COVID-19 pandemic, together with resulting voluntary and government-imposed actions, has disrupted the global economy, increased market volatility, and resulted in significant fluctuations in the valuation of investment securities.

Market fluctuations and volatility may cause clients to choose to redeem their investments in our strategies (upon short or no notice), as well as increase the likelihood and consequences of trading, valuation, or other operational errors.

The COVID-19 pandemic has also impacted the manner in which we operate. As of the date of this filing, the majority of our employees are working from home and we have significantly reduced business travel. Additionally, many third-party vendors on whom we rely for certain critical functions are also operating in remote environments.

We believe we are operating well under these circumstances. We are benefiting from the flexible and highly mobile operating environment we have built over 25 years. However, we do not know what, if any, longer-term impact the current circumstances (and/or the extension of them) will have on our business and results. Most of our associates have never operated remotely for extended periods of time. And many of our associates typically travel extensively to conduct investment research; interact with clients, prospects and intermediaries; and/or manage our global business.

In addition, despite the precautions we have taken to protect the safety and well-being of our associates, no assurance can be given that our associates will not contract COVID-19. The loss of any of our key professionals (including portfolio managers and other senior leaders at our firm) for an extended period may prevent us from sustaining the historically strong investment performance we have achieved; adversely affect our ability to retain existing and attract new clients; and/or negatively impact our ability to operate our business and execute our long-term strategy.

For a discussion of related and other potential risks and uncertainties, see the information under the heading “Risk Factors” in our latest annual report on Form 10-K, which is accessible on the SEC’s website at www.sec.gov.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Unregistered Sales of Equity Securities

As described in Note 8, “Stockholders’ Equity”, to the Unaudited Consolidated Financial Statements included in Part I of this report, upon termination of employment with Artisan, an employee-partner’s Class B common units are exchanged for Class E common units and the corresponding shares of APAM Class B common stock are canceled. APAM issues the former employee-partner a number of shares of APAM Class C common stock equal to the former employee-partner’s number of Class E common units. Class E common units are exchangeable for Class A common stock subject to the same restrictions and limitations on exchange applicable to the other common units of Holdings. There were no such issuances during the three months ended September 30, 2020.

Item 3. Defaults Upon Senior Securities

None

Item 4. Mine Safety Disclosures

Not applicable

Item 5. Other Information

None.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Nature of Business and Organization

Note 1. Nature of Business and Organization

Nature of Business

Artisan Partners Asset Management Inc. (“APAM”), through its subsidiaries, is an investment management firm focused on providing high-value added, active investment strategies to sophisticated clients globally. APAM and its subsidiaries are hereafter referred to collectively as “Artisan” or the “Company”.

Artisan’s autonomous investment teams manage a broad range of U.S., non-U.S. and global investment strategies that are diversified by asset class, market cap and investment style. Strategies are offered through multiple investment vehicles to accommodate a broad range of client mandates. Artisan offers its investment management services primarily to institutions and through intermediaries that operate with institutional-like decision-making processes and have long-term investment horizons.

Organization

On March 12, 2013, APAM completed its initial public offering (the “IPO”). APAM was formed for the purpose of becoming the general partner of Artisan Partners Holdings LP (“Artisan Partners Holdings” or “Holdings”) in connection with the IPO. Holdings is a holding company for the investment management business conducted under the name “Artisan Partners”. The reorganization (“IPO Reorganization”) established the necessary corporate structure to complete the IPO while at the same time preserving the ability of the firm to conduct operations through Holdings and its subsidiaries.

As the sole general partner, APAM controls the business and affairs of Holdings. As a result, APAM consolidates Holdings’ financial statements and records a noncontrolling interest for the equity interests in Holdings held by the limited partners of Holdings. At September 30, 2020, APAM held approximately 78% of the equity ownership interest in Holdings.

Holdings, together with its wholly owned subsidiary, Artisan Investments GP LLC, controls a 100% interest in Artisan Partners Limited Partnership (“APLP”), a multi-product investment management firm that is the principal operating subsidiary of Artisan Partners Holdings. APLP is registered as an investment adviser with the U.S. Securities and Exchange Commission under the Investment Advisers Act of 1940. APLP provides investment advisory services to traditional separate accounts and pooled investment vehicles, including Artisan Partners Funds, Inc. (“Artisan Funds”), Artisan Partners Global Funds plc (“Artisan Global Funds”), and Artisan sponsored private funds (“Artisan Private Funds”). Artisan Funds are a series of open-end, diversified mutual funds registered under the Investment Company Act of 1940, as amended. Artisan Global Funds is a family of Ireland-domiciled UCITS.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 2. Summary of Significant Accounting Policies

Basis of presentation

The accompanying financial statements are unaudited. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of such consolidated financial statements have been included. Such interim results are not necessarily indicative of full year results.

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting and accordingly they do not include all of the information and footnotes required in the annual consolidated financial statements and accompanying footnotes.

The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. As a result, the interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in APAM’s latest annual report on Form 10-K.

The accompanying financial statements were prepared in accordance with U.S. GAAP and related rules and regulations of the SEC. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates or assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from these estimates or assumptions.

Principles of consolidation

Artisan’s policy is to consolidate all subsidiaries or other entities in which it has a controlling financial interest. The consolidation guidance requires an analysis to determine if an entity should be evaluated for consolidation using the voting interest entity (“VOE”) model or the variable interest entity (“VIE”) model. Under the VOE model, controlling financial interest is generally defined as a majority ownership of voting interests. Under the VIE model, controlling financial interest is defined as (i) the power to direct activities that most significantly impact the economic performance of the entity and (ii) the right to receive potentially significant benefits or the obligation to absorb potentially significant losses.

Artisan generally consolidates VIEs in which it meets the power criteria and holds an equity ownership interest of greater than 10%. The consolidated financial statements include the accounts of APAM and all subsidiaries or other entities in which APAM has a direct or indirect controlling financial interest. All material intercompany balances have been eliminated in consolidation.

Artisan serves as the investment adviser to Artisan Funds, Artisan Global Funds and Artisan Private Funds. Artisan Funds and Artisan Global Funds are corporate entities the business and affairs of which are managed by their respective boards of directors. The shareholders of the funds retain voting rights, including rights to elect and reelect members of their respective boards of directors. Each series of Artisan Funds is a VOE and is separately evaluated for consolidation under the VOE model. The shareholders of Artisan Global Funds lack simple majority liquidation rights, and as a result, each sub-fund of Artisan Global Funds is evaluated for consolidation under the VIE model. Artisan Private Funds are also evaluated for consolidation under the VIE model because third-party equity holders of the funds generally lack the ability to divest Artisan of its control of the funds.

From time to time, the Company makes investments in Artisan Funds, Artisan Global Funds, and Artisan Private Funds. If the investment results in a controlling financial interest, APAM consolidates the fund, and the underlying activity of the entire fund is included in Artisan’s Unaudited Consolidated Financial Statements. As of September 30, 2020, Artisan had a controlling financial interest in three sub-funds of Artisan Global Funds and three Artisan Private Funds and, as a result, these funds are included in Artisan’s Unaudited Consolidated Financial Statements. Because these consolidated investment products meet the definition of investment companies under U.S. GAAP, Artisan has retained the specialized industry accounting principles for investment companies in the consolidated financial statements. See Note 6, “Variable Interest Entities and Consolidated Investment Products” for additional details.

Recent accounting pronouncements

Accounting standards adopted as of January 1, 2020

In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The capitalized implementation costs will be expensed over the term of the hosting arrangement. The Company adopted the new guidance on January 1, 2020. The Company capitalized $868 thousand of software implementation costs and recorded $40 thousand of related amortization expense during the nine months ended September 30, 2020.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses, which requires entities to measure credit losses on financial assets based on expected losses rather than incurred losses. The guidance was effective on January 1, 2020 and requires a modified retrospective approach to adoption. The adoption of this guidance did not have an impact on the consolidated financial statements.

In accordance with ASC 820, fair value is defined as the price that Artisan would receive upon selling an investment in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. The following three-tier fair value hierarchy prioritizes the inputs used in measuring fair value:

•Level 1 – Observable inputs such as quoted (unadjusted) market prices in active markets for identical securities.

•Level 2 – Other significant observable inputs (including but not limited to quoted prices for similar instruments, interest rates, prepayment speeds, credit risk, etc.).

•Level 3 – Significant unobservable inputs (including Artisan’s own assumptions in determining fair value).

The following provides the hierarchy of inputs used to derive fair value of Artisan’s assets and liabilities that are financial instruments as of September 30, 2020 and December 31, 2019:

	Assets and Liabilities at Fair Value
	Total		NAV Practical Expedient (No Fair Value Level)		Level 1		Level 2		Level 3
September 30, 2020
Assets
Money market funds	$	70,854	$	—	$	70,854	$	—	$	—

Money market funds	$	30,673	$	—	$	30,673	$	—	$	—
Equity securities	23,878		15,068		8,810		—		—

Fair values determined based on Level 1 inputs utilize quoted market prices for identical assets. Level 1 assets generally consist of money market funds, open-end mutual funds and UCITS funds. Equity securities without a fair value level consist of the Company’s investments in Artisan Private Funds, which are measured at the underlying fund’s net asset value (“NAV”), using the ASC 820 practical expedient. The NAV is provided by the fund and is derived from the fair values of the underlying investments as of the reporting date. Cash maintained in demand deposit accounts is excluded from the table above.

Variable Interest Entities and Consolidated Investment Products

Note 6. Variable Interest Entities and Consolidated Investment Products

Artisan serves as the investment adviser for various types of investment products, consisting of both VIEs and VOEs. Artisan consolidates an investment product if it has a controlling financial interest in the entity. Any such entities are collectively referred to herein as consolidated investment products or CIPs.

As of September 30, 2020, Artisan is considered to have a controlling financial interest in three sub-funds of Artisan Global Funds and three Artisan Private Funds, with an aggregate direct equity investment in the consolidated investment products of $51.2 million.

Artisan’s maximum exposure to loss in connection with the assets and liabilities of CIPs is limited to its direct equity investment, while the potential benefit is limited to the management and performance fees received and the return on its equity investment. With the exception of Artisan’s direct equity investment, the assets of CIPs are not available to Artisan’s creditors, nor are they available to Artisan for general corporate purposes. In addition, third-party investors in the CIPs have no recourse to the general credit of the Company.

Management and performance fees earned from CIPs are eliminated from revenue upon consolidation. See Note 14, “Related Party Transactions” for additional information on management and performance fees earned from CIPs.

Third-party investors’ ownership interest in CIPs is presented as redeemable noncontrolling interest in the Unaudited Condensed Consolidated Statements of Financial Condition as third-party investors have the right to withdraw their capital, subject to certain conditions. Net income attributable to third-party investors is reported as net income attributable to noncontrolling interests - consolidated investment products in the Unaudited Consolidated Statements of Operations.

During the nine months ended September 30, 2020, the Company determined that it no longer had a controlling financial interest in one sub-fund of Artisan Global Funds as a result of third party capital contributions. Upon loss of control, the VIE was deconsolidated and the related assets, liabilities, and equity of the fund were derecognized from the Company’s Unaudited Condensed Consolidated Statements of Financial Condition. There was no net impact to the Unaudited Consolidated Statements of Operations for the nine months ended September 30, 2020. Artisan generally does not recognize a gain or loss upon deconsolidation of investment products because the assets and liabilities of CIPs are carried at fair value. Upon deconsolidation, Artisan’s $1.5 million direct equity investment was reclassified from investment assets of consolidated investment products to investment securities in the Company’s Unaudited Condensed Consolidated Statements of Financial Condition.

As of September 30, 2020, Artisan held direct equity investments of $2.5 million in VIEs for which the Company does not hold a controlling financial interest. These direct equity investments consisted of seed investments in sub-funds of Artisan Global Funds and Artisan Private Funds, both of which are accounted for under the equity method of accounting because Artisan has significant influence over the funds.

Fair Value Measurements - Consolidated Investment Products

The carrying value of CIPs’ investments is also their fair value. Short and long positions on equity securities are valued based upon closing prices of the security on the exchange or market designated by the accounting agent or pricing vendor as the principal exchange. The closing price may represent last sale price, official closing price, a closing auction or other information depending on market convention. Short and long positions on fixed income instruments are valued at market value. Market values are generally evaluations based on the judgment of pricing vendors, which may consider, among other factors, the prices at which securities actually trade, broker-dealer quotations, pricing formulas, estimates of market values obtained from yield data relating to investments or securities with similar characteristics and/or discounted cash flow models that might be applicable.

The following tables present the fair value hierarchy levels of assets and liabilities held by CIPs measured at fair value as of September 30, 2020 and December 31, 2019:

Noncontrolling interest - Holdings

Noncontrolling Interest [Abstract]

Noncontrolling interest - Holdings

Note 7. Noncontrolling interests - Holdings

Net income attributable to noncontrolling interests - Artisan Partners Holdings in the Unaudited Consolidated Statements of Operations represents the portion of earnings or loss attributable to the equity ownership interests in Holdings held by the limited partners of Holdings. As of September 30, 2020, APAM held approximately 78% of the equity ownership interests in Holdings.

Limited partners of Artisan Partners Holdings are entitled to exchange partnership units (along with a corresponding number of shares of Class B or C common stock of APAM) for shares of Class A common stock from time to time (the “Holdings Common Unit Exchanges”). The Holdings Common Unit Exchanges increase APAM’s equity ownership interest in Holdings and result in an increase to deferred tax assets and amounts payable under the tax receivable agreements. See Note 11, “Income Taxes and Related Payments”.

In order to maintain the one-to-one correspondence of the number of Holdings partnership units and APAM common shares, Holdings will issue one general partner (“GP”) unit to APAM for each share of Class A common stock issued by APAM. For the nine months ended September 30, 2020, APAM’s equity ownership interest in Holdings increased as a result of the following transactions:

	Holdings GP Units	Limited Partnership Units	Total	APAM Ownership %
Balance at December 31, 2019	56,429,825	21,372,029	77,801,854	73	%
2020 Follow-On Offering	1,802,326	(1,802,326)	—	2	%

Balance at September 30, 2020	61,425,521	17,149,579	78,575,100	78	%

(1) The impact of the transaction on APAM’s ownership percentage was less than 1%.

Changes in ownership of Holdings are accounted for as equity transactions because APAM continues to have a controlling interest in Holdings. Additional paid-in capital and noncontrolling interests - Artisan Partners Holdings in the Unaudited Condensed Consolidated Statements of Financial Condition are adjusted to reallocate Holdings’ historical equity to reflect the change in APAM’s ownership of Holdings.

The reallocation of equity had the following impact on the Unaudited Condensed Consolidated Statements of Financial Condition:

Statement of Financial Condition	For the Nine Months Ended September 30,
	2020		2019
Additional paid-in capital	$	(740)	$	(2,455)
Noncontrolling interests - Artisan Partners Holdings	742		2,501
Accumulated other comprehensive income (loss)	(2)		(46)
Net impact to financial condition	$	—	$	—

In addition to the reallocation of historical equity, the change in ownership resulted in an increase to deferred tax assets and additional paid-in capital of $2.0 million and $0.6 million for the nine months ended September 30, 2020 and 2019, respectively.

(1) The Company’s employees to whom Artisan has granted equity have entered into a stockholders agreement with respect to all shares of APAM common stock they have acquired from the Company and any shares they may acquire from the Company in the future, pursuant to which they granted an irrevocable voting proxy to a Stockholders Committee. As of September 30, 2020, Artisan’s employees held 5,186,737 restricted shares of Class A common stock and all 5,519,415 outstanding shares of Class B common stock, all of which were subject to the agreement.

APAM is dependent on cash generated by Holdings to fund any dividends. Generally, Holdings will make distributions to all of its partners, including APAM, based on the proportionate ownership each holds in Holdings. APAM will fund dividends to its stockholders from its proportionate share of those distributions after provision for its taxes and other obligations. APAM declared and paid the following dividends per share during the three and nine months ended September 30, 2020 and 2019:

Type of Dividend	Class of Stock	For the Three Months Ended September 30,				For the Nine Months Ended September 30,

(1) There were 304,570 and 297,891 restricted stock units outstanding at September 30, 2020 and December 31, 2019, respectively. In addition, there were 60,000 performance share units outstanding at September 30, 2020. Based on the current status of the market and performance conditions, the 60,000 unvested performance share units would ultimately result in the issuance of 90,000 shares of Class A common stock if all other vesting conditions were met. Restricted stock units and performance share units are not reflected in the table because they are not considered outstanding or issued stock.

Each Class A, Class B, Class D and Class E common unit of Holdings (together with the corresponding share of Class B or Class C common stock) is exchangeable for one share of Class A common stock. The corresponding shares of Class B and Class C common stock are immediately canceled upon any such exchange.

Upon termination of employment with Artisan, an employee-partner’s Class B common units are exchanged for Class E common units and the corresponding shares of Class B common stock are canceled. APAM issues the former employee-partner a number of shares of Class C common stock equal to the former employee-partner’s number of Class E common units. Class E common units are exchangeable for Class A common stock subject to the same restrictions and limitations on exchange applicable to the other common units of Holdings.

Artisan Partners Holdings - Partners’ Equity

Holdings makes distributions of its net income to the holders of its partnership units for income taxes as required under the terms of the partnership agreement and also makes additional distributions under the terms of the partnership agreement. The distributions are recorded in the financial statements on the declaration date, or on the payment date in lieu of a declaration date. Holdings’ partnership distributions for the three and nine months ended September 30, 2020 and 2019, were as follows:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2020		2019		2020		2019

Total Holdings Partnership Distributions	$	90,947	$	75,251	$	241,624	$	236,459

The distributions are recorded as a reduction to consolidated stockholders’ equity, with the exception of distributions made to APAM, which are eliminated upon consolidation.

(1) Separate account revenue consists of management fees and performance fees earned from vehicles other than Artisan Funds or Artisan Global Funds, which includes traditional separate accounts, Artisan-branded collective investment trusts and funds (both public and private) that Artisan advises, including Artisan Private Funds.
(2) All management fees and performance fees from consolidated investment products are eliminated upon consolidation and therefore are omitted from this table.

Performance fees are subject to the uncertainty of market volatility, and as a result, the entire amount of the variable consideration related to performance fees is constrained until the end of each measurement period. At the end of the quarterly or annual measurement period, revenue is recorded for the actual amount of performance fees earned during that period because the uncertainty has been resolved. For performance fees with annual measurement periods, revenue recognized in the current quarter relates to performance obligations that were partially satisfied in prior periods.

The following table presents the balances of receivables related to contracts with customers:

	As of September 30, 2020		As of December 31, 2019

Non-customer receivables	6,677		2,164
Accounts receivable	$	98,420	$	81,868

Artisan Funds and Artisan Global Funds are billed on the last day of each month. Artisan Funds and Artisan Global Funds make payments on the same day the invoice is received for the majority of the invoiced amount. The remainder of the invoice is generally paid in the month following receipt of the invoice. Separate account clients are generally billed on a monthly or quarterly basis, with payments due within 30 days of billing. Artisan had no other contract assets or liabilities from contracts with customers as of September 30, 2020 or December 31, 2019.

Total compensation and benefits	$	108,657	$	99,847	$	315,578	$	300,615
(1) Excluding restricted share-based award compensation expense

Incentive compensation

Cash incentive compensation paid to members of Artisan’s investment teams and members of its distribution teams is generally based on formulas that are tied directly to revenues. These payments are made in the quarter following the quarter in which the incentive was earned with the exception of fourth quarter payments which are paid in the fourth quarter of the year. Cash incentive compensation paid to most other employees is discretionary and subjectively determined based on individual performance and Artisan’s overall results during the applicable year and is generally paid on an annual basis.

Restricted share-based awards

Artisan has registered 14,000,000 shares of Class A common stock for issuance under the 2013 Omnibus Incentive Compensation Plan (the “Plan”). Pursuant to the Plan, APAM has granted a combination of restricted stock awards, restricted stock units, and performance share units (collectively referred to as “restricted share-based awards” or "awards") of Class A common stock to employees.

Standard Restricted Shares. Standard restricted shares are generally subject to a pro rata five-year service vesting condition.

Career Shares. Career shares are generally subject to both (i) a pro rata five-year service vesting condition and (ii) a qualifying retirement (as defined in the award agreement).

Franchise Shares. Like career shares, franchise shares are generally subject to both (i) a pro rata five-year service vesting condition and (ii) a qualifying retirement condition. In addition, franchise shares, which are only granted to investment team members, are subject to a Franchise Protection Clause, which provides that the number of shares that ultimately vest depends on whether certain conditions relating to client cash flows are met. If such conditions are not met, compensation cost will be reversed for any shares that do not vest.

Performance Share Units (PSUs). PSUs are generally subject to (i) a three-year service vesting condition, (ii) certain performance conditions related to the Company's operating margin and total shareholder return compared to a peer group during a three-year performance period, and (iii) for one-half of the PSUs eligible to vest at the end of the performance period, a qualifying retirement condition. The number of shares of Class A common stock that are ultimately issued in connection with each PSU award will depend upon the outcome of the performance, market and qualified retirement conditions. For the portion of a PSU award with a "performance condition" under ASC 718, expense is recognized over the service period if it is probable that the performance condition will be achieved.

Compensation expense is recognized based on the estimated grant date fair value on a straight-line basis over the requisite service period of the award. The initial requisite service period is generally five years for restricted stock awards and restricted stock units, and three years for performance share units. The fair value of each award is equal to the market price of the Company's common stock on the grant date, except for performance share units with a "market condition" performance metric under ASC 718, which have a grant-date fair value based on a Monte Carlo valuation model.

Unvested restricted share-based awards are subject to forfeiture. The Company’s accounting policy is to record the impact of forfeitures when they occur. Grantees are generally entitled to dividends or dividend equivalents on unvested and vested awards. 4,631,934 shares of Class A common stock were reserved and available for issuance under the Plan as of September 30, 2020.

During the nine months ended September 30, 2020, Artisan granted 916,085 restricted stock awards, 3,370 restricted stock units, and 60,000 performance share units of Class A common stock to employees of the Company. Total compensation expense associated with the 2020 grant is expected to be approximately $34.1 million.

The following tables summarize the restricted share-based award activity for the nine months ended September 30, 2020:

	Weighted-Average Grant Date Fair Value		Restricted Stock Awards and Restricted Stock Units
Unvested at January 1, 2020	$	35.00	5,005,422
Granted	33.80		919,455
Forfeited	30.71		(40,101)
Vested	32.59		(588,144)
Unvested at September 30, 2020	$	35.09	5,296,632

	Weighted-Average Grant Date Fair Value		Performance Share Units
Unvested at January 1, 2020	$	—	—
Granted	52.45		60,000
Forfeited	—		—
Vested	—		—
Unvested at September 30, 2020	$	52.45	60,000

Based on the current status of the market and performance conditions, the 60,000 unvested performance share units would ultimately result in the issuance of 90,000 shares of Class A common stock if all other vesting conditions were met.

The unrecognized compensation expense for all unvested awards as of September 30, 2020 was $88.0 million with a weighted average recognition period of 3.3 years remaining.

During the nine months ended September 30, 2020, the Company withheld a total of 126,971 restricted shares and paid $4.5 million as a result of net share settlements to satisfy employee tax withholding obligations. These net share settlements had the effect of shares repurchased and retired by the Company, as they reduced the number of shares outstanding.

Income Taxes and Related Payments

Note 11. Income Taxes and Related Payments

APAM is subject to U.S. federal, state and local income taxation on APAM’s allocable portion of Holdings’ income as well as foreign income taxes payable by Holdings’ subsidiaries. APAM’s effective income tax rate was lower than the U.S. federal statutory rate of 21% primarily due to a rate benefit attributable to the fact that, for the nine months ended September 30, 2020, approximately 25% of Artisan Partners Holdings’ full year projected taxable earnings were attributable to other partners and not subject to corporate-level taxes. The effective tax rate was also lower than the statutory rate due to dividends paid on unvested share-based awards.

APAM’s effective tax rate was 18.1% and 7.3% for the nine months ended September 30, 2020 and 2019, respectively.

Components of the provision for income taxes consist of the following:

In connection with the IPO, APAM entered into two tax receivable agreements (“TRAs”). The first TRA generally provides for the payment by APAM to a private equity fund (the “Pre-H&F Corp Merger Shareholder”) or its assignees of 85% of the applicable cash savings, if any, of U.S. federal, state and local income taxes that APAM actually realizes (or is deemed to realize in certain circumstances) as a result of (i) the tax attributes of the preferred units APAM acquired in the merger of a wholly-owned subsidiary of the Pre-H&F Corp Merger Shareholder into APAM in March 2013, (ii) net operating losses available as a result of the merger and (iii) tax benefits related to imputed interest.

The second TRA generally provides for the payment by APAM to current or former limited partners of Holdings or their assignees of 85% of the applicable cash savings, if any, of U.S. federal, state and local income taxes that APAM actually realizes (or is deemed to realize in certain circumstances) as a result of (i) certain tax attributes of their partnership units sold to APAM or exchanged (for shares of Class A common stock, convertible preferred stock or other consideration) and that are created as a result of such sales or exchanges and payments under the TRAs and (ii) tax benefits related to imputed interest. Under both agreements, APAM generally will retain the benefit of the remaining 15% of the applicable tax savings.

For purposes of the TRAs, cash savings of income taxes are calculated by comparing APAM’s actual income tax liability to the amount it would have been required to pay had it not been able to utilize any of the tax benefits subject to the TRAs, unless certain assumptions apply. The TRAs will continue in effect until all such tax benefits have been utilized or expired, unless APAM exercises its right to terminate the agreements or payments under the agreements are accelerated in the event that APAM materially breaches any of its material obligations under the agreements.

The actual increase in tax basis, as well as the amount and timing of any payments under these agreements, will vary depending upon a number of factors, including the timing of sales or exchanges by the holders of limited partnership units, the price of the Class A common stock at the time of such sales or exchanges, whether such sales or exchanges are taxable, the amount and timing of the taxable income APAM generates in the future and the tax rate then applicable and the portion of APAM’s payments under the TRAs constituting imputed interest or depreciable basis or amortizable basis.

Payments under the TRAs, if any, will be made pro rata among all TRA counterparties entitled to payments on an annual basis to the extent APAM has sufficient taxable income to utilize the increased depreciation and amortization charges and imputed interest deductions. Artisan expects to make one or more payments under the TRAs, to the extent they are required, prior to or within 125 days after APAM’s U.S. federal income tax return is filed for each fiscal year. Interest on the TRA payments will accrue at a rate equal to one-year LIBOR plus 100 basis points from the due date (without extension) of such tax return until such payments are made.

Amounts payable under tax receivable agreements are estimates which may be impacted by factors, including but not limited to, expected tax rates, projected taxable income, and projected ownership levels and are subject to change. Changes in the estimates of amounts payable under tax receivable agreements are recorded as non-operating income (loss) in the Unaudited Consolidated Statements of Operations.

The change in the Company’s deferred tax assets related to the tax benefits described above and the change in corresponding amounts payable under the TRAs for the nine months ended September 30, 2020 is summarized as follows:

	Deferred Tax Asset - Amortizable basis		Amounts payable under tax receivable agreements
December 31, 2019	$	408,140	$	375,324
2020 Follow-On Offering	21,424		18,211

Payments under TRA	—		(26,943)
Change in estimate	(61)		(238)
September 30, 2020	$	426,093	$	385,984

Net deferred tax assets comprise the following:

	As of September 30, 2020		As of December 31, 2019
Deferred tax assets:
Amortizable basis (1)	$	426,093	$	408,140
Other (2)	32,605		27,757
Total deferred tax assets	458,698		435,897
Less: valuation allowance (3)	—		—
Net deferred tax assets	$	458,698	$	435,897
(1) Represents the unamortized step-up of tax basis and other tax attributes from the merger and partnership unit sales and exchanges described above. These future tax benefits are subject to the TRA agreements.
(2) Represents the net deferred tax assets associated with the merger described above and other miscellaneous deferred tax assets. These future tax benefits are not subject to the TRA agreements.
(3) Artisan assessed whether the deferred tax assets would be realizable and determined based on its history of taxable income that the benefits would more likely than not be realized. Accordingly, no valuation allowance is required.

Accounting standards establish a minimum threshold for recognizing, and a process for measuring, the benefits of income tax return positions in financial statements. The Company's gross liability for unrecognized tax benefits was $1.5 million and $2.0 million as of September 30, 2020 and December 31, 2019, respectively. The total amount of unrecognized tax benefits is not expected to significantly increase or decrease within the next twelve months.

The Company recognizes interest and penalties related to unrecognized tax benefits as a component of the income tax provision. Accrued interest on uncertain tax positions was $0.3 million as of September 30, 2020 and December 31, 2019. The gross unrecognized tax benefit is recorded within accounts payable, accrued expenses, and other in the Company’s Unaudited Condensed Consolidated Statements of Financial Condition.

In the normal course of business, Artisan is subject to examination by federal and certain state, local and foreign tax regulators. As of September 30, 2020, U.S. federal income tax returns filed for the years 2017 through 2019 are open and therefore subject to examination. State, local, and foreign income tax returns filed are generally subject to examination from 2016 to 2019.

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

Note 12. Earnings Per Share

Basic earnings per share is computed under the two-class method by dividing income available to Class A common stockholders by the weighted average number of Class A common shares outstanding during the period. Unvested restricted share-based awards are excluded from the number of Class A common shares outstanding for the basic earnings per share calculation because the shares have not yet been earned by employees. Income available to Class A common stockholders is computed by reducing net income attributable to APAM by earnings (both distributed and undistributed) allocated to participating securities, according to their respective rights to participate in those earnings. Except for certain performance share units, unvested share-based awards are participating securities because the awards include non-forfeitable dividend rights during the vesting period. Class B and Class C common shares do not share in profits of APAM and therefore are not reflected in the calculations.

Diluted earnings per share is computed under the more dilutive of the treasury stock method or the two-class method. The weighted average number of Class A common shares outstanding during the period is increased by the assumed conversion of nonparticipating unvested share-based awards into Class A common stock using the treasury stock method.

The computation of basic and diluted earnings per share for the three and nine months ended September 30, 2020 and 2019 were as follows:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
Basic and Diluted Earnings Per Share	2020		2019		2020		2019
Numerator:
Net income attributable to APAM	$	58,527	$	41,256	$	139,503	$	111,983
Less: Allocation to participating securities	6,006		4,494		16,944		16,521
Net income available to common stockholders	$	52,521	$	36,762	$	122,559	$	95,462
Denominator:
Basic weighted average shares outstanding	56,402,503		51,448,938		55,188,563		50,950,618
Dilutive effect of nonparticipating equity awards	5,769		—		1,923		—
Diluted weighted average shares outstanding	56,408,272		51,448,938		55,190,486		50,950,618
Earnings per share - Basic	$	0.93	$	0.71	$	2.22	$	1.87
Earnings per share - Diluted	$	0.93	$	0.71	$	2.22	$	1.87

Allocation to participating securities in the table above primarily represents dividends paid to holders of unvested restricted share-based awards, which reduces net income available to common stockholders.

The Holdings limited partnership units are anti-dilutive primarily due to the impact of public company expenses. Unvested restricted share-based awards with non-forfeitable dividend rights during the vesting period are considered participating securities and are therefore anti-dilutive. The following table summarizes the weighted-average shares outstanding that are excluded from the calculation of diluted earnings per share because their effect would have been anti-dilutive:

	For the Three Months Ended September 30,		For the Nine Months Ended September 30,
Anti-Dilutive Weighted Average Shares Outstanding	2020	2019	2020	2019
Holdings limited partnership units	17,177,313	21,594,086	18,308,766	21,958,470

Summary of Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of presentation

Basis of presentation

The accompanying financial statements are unaudited. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of such consolidated financial statements have been included. Such interim results are not necessarily indicative of full year results.

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting and accordingly they do not include all of the information and footnotes required in the annual consolidated financial statements and accompanying footnotes.

The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. As a result, the interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in APAM’s latest annual report on Form 10-K.

The accompanying financial statements were prepared in accordance with U.S. GAAP and related rules and regulations of the SEC. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates or assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from these estimates or assumptions.

Principles of consolidation

Principles of consolidation

Artisan’s policy is to consolidate all subsidiaries or other entities in which it has a controlling financial interest. The consolidation guidance requires an analysis to determine if an entity should be evaluated for consolidation using the voting interest entity (“VOE”) model or the variable interest entity (“VIE”) model. Under the VOE model, controlling financial interest is generally defined as a majority ownership of voting interests. Under the VIE model, controlling financial interest is defined as (i) the power to direct activities that most significantly impact the economic performance of the entity and (ii) the right to receive potentially significant benefits or the obligation to absorb potentially significant losses.

Artisan generally consolidates VIEs in which it meets the power criteria and holds an equity ownership interest of greater than 10%. The consolidated financial statements include the accounts of APAM and all subsidiaries or other entities in which APAM has a direct or indirect controlling financial interest. All material intercompany balances have been eliminated in consolidation.

Artisan serves as the investment adviser to Artisan Funds, Artisan Global Funds and Artisan Private Funds. Artisan Funds and Artisan Global Funds are corporate entities the business and affairs of which are managed by their respective boards of directors. The shareholders of the funds retain voting rights, including rights to elect and reelect members of their respective boards of directors. Each series of Artisan Funds is a VOE and is separately evaluated for consolidation under the VOE model. The shareholders of Artisan Global Funds lack simple majority liquidation rights, and as a result, each sub-fund of Artisan Global Funds is evaluated for consolidation under the VIE model. Artisan Private Funds are also evaluated for consolidation under the VIE model because third-party equity holders of the funds generally lack the ability to divest Artisan of its control of the funds.

From time to time, the Company makes investments in Artisan Funds, Artisan Global Funds, and Artisan Private Funds. If the investment results in a controlling financial interest, APAM consolidates the fund, and the underlying activity of the entire fund is included in Artisan’s Unaudited Consolidated Financial Statements. As of September 30, 2020, Artisan had a controlling financial interest in three sub-funds of Artisan Global Funds and three Artisan Private Funds and, as a result, these funds are included in Artisan’s Unaudited Consolidated Financial Statements. Because these consolidated investment products meet the definition of investment companies under U.S. GAAP, Artisan has retained the specialized industry accounting principles for investment companies in the consolidated financial statements. See Note 6, “Variable Interest Entities and Consolidated Investment Products” for additional details.

Recent accounting pronouncements

Recent accounting pronouncements

Accounting standards adopted as of January 1, 2020

In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The capitalized implementation costs will be expensed over the term of the hosting arrangement. The Company adopted the new guidance on January 1, 2020. The Company capitalized $868 thousand of software implementation costs and recorded $40 thousand of related amortization expense during the nine months ended September 30, 2020.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses, which requires entities to measure credit losses on financial assets based on expected losses rather than incurred losses. The guidance was effective on January 1, 2020 and requires a modified retrospective approach to adoption. The adoption of this guidance did not have an impact on the consolidated financial statements.
