SCHEDULE 13D


CUSIP No. 04316A-108		Page 6 of 7

This Amendment No. 4 to Schedule 13D (this “Amendment No. 4”) amends or amends and restates, where indicated, the statement on Schedule 13D relating to the Class A common stock of the Company filed by the Reporting Persons with the Securities and Exchange Commission on March 20, 2013, as amended on July 22, 2013, November 12, 2013 and March 13, 2014. Capitalized terms used in this Amendment No. 4 but not otherwise defined herein have the meanings given to them in the initial Schedule 13D.

Amendment No. 4 is being made to reflect reductions in the amount and percentage deemed to be beneficially owned by the Reporting Persons as a result of a sale by the Reporting Persons.

Except as otherwise set forth herein, this Amendment No. 4 does not modify any of the information previously reported by the Reporting Persons in the Schedule 13D as amended to date.

5. Interest in Securities of the Issuer

(a) – (b) The Reporting Persons share investment power over 6,955,973 Class D Common Units which have economic rights but no voting power and share voting power over an equal number of shares of Class C Common Stock which have voting power but no economic rights. The Class D Common Units are exchangeable for the same number of shares of Class A Common Stock. The Class C Common Stock would be cancelled in the event that the Class D Common Units were exchanged. Accordingly, the securities beneficially owned by the Reporting Persons represent the right to acquire 6,955,973 shares of Class A Common Stock. The securities beneficially owned by the Reporting Persons represent 15.1% of the shares of Class A Common Stock that would be outstanding if the Class D Units were exchanged. As of March 9, 2015, there were 39,135,133 shares of Class A common stock outstanding according to information provided by the Company.

(c) On March 9, 2015, AIC sold 1,227,525 Class D Common Units to the Company for $46.08 per Unit and an equal number of shares of Class C Common Stock were cancelled for no consideration.
