Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On August 26, 2015 (the “Merger Date”), Accenture SCA, a Luxembourg partnership limited by shares and direct subsidiary of Accenture plc, and Accenture Holdings plc, an Irish company and direct subsidiary of Accenture plc (“Accenture Holdings”), completed the previously announced merger (the “Merger”) pursuant to the common draft terms of merger dated May 18, 2015, in which Accenture SCA was merged with and into Accenture Holdings, with Accenture Holdings as the surviving entity and Accenture SCA was dissolved without going into liquidation. In connection with the Merger, by operation of law, contracts, agreements and instruments to which Accenture SCA was a party are construed and have effect as if Accenture Holdings had been a party thereto instead of Accenture SCA, and Accenture Holdings has the same rights and is subject to the same obligations to which Accenture SCA was subject under such contracts, agreements and instruments.

The information included under Item 8.01 is incorporated by reference herein.

The description of the Merger under Item 8.01 is incorporated by reference herein.

On the Merger Date, the mandate of Accenture plc as the general partner and manager of Accenture SCA expired and the discharge (quitus) of Accenture plc as the general partner and manager of Accenture SCA in respect of the performance of its duties occurred. Accenture Holdings is governed by a board of directors.

The Merger

In connection with the Merger, by operation of law, (i) all of the assets and liabilities of Accenture SCA were transferred to Accenture Holdings, (ii) each holder of Accenture SCA’s Class I common shares (other than Accenture SCA itself) received one ordinary share of Accenture Holdings in exchange for every Class I common share held by such holder immediately before the Merger, (iii) all legal proceedings pending by or against Accenture SCA are continued with the substitution, for Accenture SCA, of Accenture Holdings as a party, and (iv) contracts, agreements and instruments to which Accenture SCA was a party are construed and have effect as if Accenture Holdings had been a party thereto instead of Accenture SCA, and Accenture Holdings has the same rights and is subject to the same obligations to which Accenture SCA was subject under such contracts, agreements and instruments. Therefore, as a result of the Merger, holders of Class I common shares of Accenture SCA became holders of ordinary shares of Accenture Holdings, and Accenture SCA ceased to exist.

Prior to the Merger, the Class I common shares of Accenture SCA were registered pursuant to Section 12(g) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). As a result of the Merger, all of the Class I common shares were cancelled and holders thereof (other than Accenture SCA itself) received ordinary shares of Accenture Holdings on a one-for-one basis. Accordingly, Accenture SCA intends to file a Form 15 with the Securities and Exchange Commission to terminate the registration of the Class I common shares of Accenture SCA and suspend its reporting obligations under Sections 13 and 15(d) of the Exchange Act.
