SCHEDULE 13D

CUSIP No. 04316A-108 Page 7 of 10

Item 3. Source and Amount of Funds or Other Consideration

AIC acquired its shares of Class C common stock and its Class D common units in connection with the reorganization of Holdings and the initial public offering of the Class A common stock, which closed on March 12, 2013. As part of the reorganization, the Company replaced AIC as the general partner of Holdings, AIC’s GP units were reclassified as Class D common units, and the Company issued AIC one share of Class C common stock corresponding to each Class D common unit. Each share of Class C common stock is entitled to one vote, but no economic rights. Pursuant to an exchange agreement (the “Exchange Agreement”) among the limited partners of Holdings and the Company, on March 12, 2014, AIC will have the right, subject to the limitations and restrictions set forth in the Exchange Agreement, to exchange each Class D common unit (along with the corresponding share of Class C common stock, which will be cancelled) for a share of Class A common stock. The Exchange Agreement is filed as Exhibit 99.2 hereto. AIC did not pay any cash consideration for its shares of Class C common stock or its Class D common units.

Also in connection with the reorganization transactions, certain limited partners of Holdings entered into a stockholders agreement (the “Stockholders Agreement”) pursuant to which the employee-partners of Holdings (each of whom owns Class B common stock) and AIC granted an irrevocable voting proxy to a stockholders committee consisting of Andrew A. Ziegler, Eric R. Colson and Daniel J. O’Keefe. Under the terms of the Stockholders Agreement, Mr. Ziegler has the sole right to determine how to vote all shares of the Class B common stock and all of AIC’s shares of Class C common stock, but in so doing he must consult with the other two members of the stockholders committee. See “Item 6”. The Stockholders Agreement is filed as Exhibit 99.3 hereto. As a result of the Stockholders Agreement, Mr. Ziegler may be deemed to have acquired beneficial ownership of all shares subject to the Stockholders Agreement. Mr. Ziegler disclaims beneficial ownership of all shares subject to the Stockholders Agreement except for those shares owned by AIC.

Item 4. Purpose of Transaction

The information set forth under Items 3 and 6 is hereby incorporated by reference.

The reorganization transactions were designed to create a capital structure that preserves the ability of Holdings to conduct its business through a partnership, while permitting it to raise additional capital and provide access to liquidity through a public company (the Company). The Stockholders Agreement consolidates control of a majority of the voting stock of the Company in, initially, Mr. Ziegler, by enabling him to elect all of the members of the Company’s board of directors (subject to the obligation under the terms of the Stockholders Agreement to vote in support of certain nominees), provided that in voting the shares subject to the Stockholders Agreement he must consult in good faith with the other two members of the committee.

(a) Mr. Ziegler may from time to time be deemed to have acquired additional shares of Class A common stock or Class B common stock that subsequently become subject to the Stockholders Agreement. Any shares of Class A common stock or Class B common stock that are issued by the Company to employee-partners or other employees of the Company will be subject to the Stockholders Agreement so long as the agreement has not been terminated. Pursuant to the Company’s 2013 Omnibus Incentive Compensation Plan (the “Omnibus Plan”), in the future, the Company expects to grant equity awards of or with respect to shares of Class A common stock or Class B common units. To the extent Holdings issues additional Class B common units to employees, those employees would be entitled to receive a corresponding number of shares of Class B common stock. Shares of Class A common stock or Class B common stock held by an employee-partner or other employee will cease to be subject to the Stockholders Agreement upon termination of employment.

(d) Mr. Ziegler’s employment as the Company’s Executive Chairman is expected to terminate on March 12, 2014, in accordance with the terms of his employment agreement. At such time, he will cease to serve on the stockholders committee and will no longer have the right to vote the shares of Class B common stock and Class C common stock subject to the Stockholders Agreement. See “Item 6”.

Except as described in this Item 4, the Reporting Persons currently have no plans or proposals that relate to or would result in any transaction, event or action set forth in subsections (a) through (j) of Item 4 of Schedule 13D. The Reporting Persons reserve the right to formulate plans or make proposals, and take such action with respect thereto, including any or all of the items set forth in subsections (a) through (j) of Item 4 of Schedule 13D and any other actions, as they may determine.

Item 5. Interest in Securities of the Issuer

(a) – (b)

Name	Aggregate Number of Shares of Class A  Common Stock Beneficially Owned		Percentage of Outstanding Class A Common Stock			Sole Voting Power		Shared Voting Power		Sole Power to Dispose		Shared Power to Dispose

Carlene M. Ziegler		9,627,644		43	%		0		0		0		9,627,644

The percentages in the column titled Percentage of Outstanding Class A Common Stock are calculated in accordance with Rule 13d-3(d)(1)(i) and thereby represent each Reporting Person’s aggregate number of shares of Class A common stock beneficially owned, divided by the sum of the total number of outstanding shares of Class A common stock and the Reporting Person’s aggregate number of shares of Class A common stock beneficially owned.

(c) The information set forth under Item 3 is hereby incorporated by reference.

(d) With respect to the 35,898,764 shares of Class A common stock beneficially owned by Mr. Ziegler, 9,627,644 of those shares are directly owned by AIC and the balance of the shares are owned by other limited partners of Holdings. Mr. Ziegler disclaims beneficial ownership of all 35,898,764 shares except for those shares owned by AIC.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

The following descriptions are qualified in their entirety by reference to the Stockholders Agreement, Exchange Agreement and Resale and Registration Rights Agreement (as defined below), all of which are incorporated by reference as Exhibits 99.3, 99.2 and 99.4 hereto, respectively, and incorporated by reference herein.

Stockholders Agreement

Concurrently with the consummation of the initial public offering of the Company, AIC and each employee-partner of Holdings entered into a Stockholders Agreement pursuant to which such persons granted an irrevocable voting proxy with respect to all shares of the Company’s common stock they held at such time or may acquire from the Company in the future to a stockholders committee consisting initially of a designee of AIC, who initially is Mr. Ziegler, Eric R. Colson (the Company’s Chief Executive Officer) and Daniel J. O’Keefe (an employee-partner of Holdings).

Mr. Ziegler, as the AIC designee, has the sole right, in consultation with the other members of the committee, to determine how to vote all shares subject to the Stockholders Agreement until the earliest to occur of: (i) Mr. Ziegler’s death or disability, (ii) the voluntary termination of Mr. Ziegler’s employment with the Company, including the scheduled expiration of his employment on March 12, 2014 and (iii) 180 days after the effective date of Mr. Ziegler’s involuntary termination of employment, at which time AIC will also lose its right to designate one member of the stockholders committee. Mr. Ziegler is required to consult in good faith, or participate in the activities of the stockholders committee so as to be available to consult in good faith, with the other members of the stockholders committee.

When the AIC designee ceases to have sole power to determine how the shares are voted, the shares will be voted in accordance with the majority decision of the three members of the stockholders committee. Although AIC may replace Mr. Ziegler as its stockholders committee designee, Mr. Ziegler controls 50% of the voting stock of AIC and could not be replaced without his consent. AIC may withdraw its shares of Class C common stock from the Stockholders Agreement when Mr. Ziegler is no longer a member of the stockholders committee. Upon such withdrawal AIC will have sole voting control over its shares.

-8-

SCHEDULE 13D

CUSIP No. 04316A-108 Page 9 of 10

The members of the stockholders committee other than the AIC designee must be employees of the Company (or one of its subsidiaries) and holders of shares subject to the Stockholders Agreement. If a member of the stockholders committee ceases to act as a member of the stockholders committee, the chief executive officer of the Company (if he or she is a holder of shares subject to the Stockholders Agreement and is not already a member of the stockholders committee) will become a member of the stockholders committee. Otherwise, the two remaining members of the stockholders committee will jointly select a third member of the stockholders committee. If the remaining members of the stockholders committee cannot agree on a third member of the stockholders committee or if there are fewer than two remaining members of the stockholders committee, then the member or members of the stockholders committee will be selected by the vote of the holders of the shares subject to the Stockholders Agreement from among candidates nominated by the five holders of shares subject to the Stockholders Agreement, other than AIC, that hold the largest number of shares of the Company’s common stock subject to the agreement.

At any time after the earlier of (i) the elimination of the Class B common stock’s supervoting rights and (ii) the fifth anniversary of the Company’s initial public offering, parties to the Stockholders Agreement holding at least two-thirds of the shares subject to the agreement may terminate it, provided that the stockholders committee is no longer obligated to vote in favor of a director nominee who is a holder of Class A common units of Holdings or a director nominee selected by the holders of a majority of the convertible preferred stock of the Company and preferred units of Holdings.

Exchange Agreement

Pursuant to the Exchange Agreement, each limited partner of Holdings will have the right, beginning on March 12, 2014, to exchange limited partnership units of Holdings for Class A common stock (or, in the case of holders of preferred units of Holdings, convertible preferred stock of the Company), subject to the restrictions and conditions set forth in the Exchange Agreement.

Resale and Registration Rights Agreement

AIC is party to a resale and registration rights agreement, dated as of March 12, 2013 (the “Resale and Registration Rights Agreement”), pursuant to which shares of Class A common stock issued upon exchange of limited partnership units of Holdings will be eligible for resale. Shares of Class A common stock received upon the exchange of limited partnership units may be transferred only in accordance with the terms and conditions of the agreement, which includes restrictions on the timing and manner of resale. In addition, AIC may exercise demand registration rights, subject to certain restrictions and conditions, under a shelf registration statement in (i) an unrestricted number of brokered transactions and (ii) during the one-year period beginning on March 12, 2014, two underwritten shelf takedowns (but only one of which may be a marketed underwritten shelf takedown), and, during each one-year period beginning on March 13, 2015, three underwritten shelf takedowns (but only one of which may be a marketed underwritten shelf takedown), subject to the limitation of two demands for marketed underwritten shelf takedowns in the aggregate. The Resale and Registration Rights Agreement is filed as Exhibit 99.4 hereto.
