This Schedule 13G relates to the Issuer’s common shares, nominal value $0.01 per share.

L5140P 101

All ownership percentages assume that there are 117,800,000 common shares outstanding, based on the Issuer’s Report on Form 6-K filed with the Securities and Exchange Commission on October 27, 2016, prior to giving effect to the conversion of equity awards held by Mr. McGlade.

The information set forth in Item 2 above is incorporated by reference.

As a result of the Governance Agreement described in Item 8 below, the other Governance Shareholders (as defined below) may be deemed to beneficially own and share voting power over certain common shares of the Issuer owned by the Reporting Person.

The information set forth in Item 2 above is incorporated by reference.

On April 23, 2013, in connection with the initial public offering of the Issuer, SLP III Investment Holding S.á r.l. (the “Silver Lake Shareholder”), Serafina S.A. (the “BC Shareholder”), Mr. McGlade (collectively with the Silver Lake Shareholder and the BC Shareholder, the “Governance Shareholders”) and the Issuer entered into a governance agreement (as amended from time to time, the “Governance Agreement”).  Under the Governance Agreement, the Silver Lake Shareholder currently has the right to nominate one director for election to the Issuer’s board of directors and the BC Shareholder currently has the right to nominate four directors for election to the Issuer’s board of directors.  The Governance Agreement also provides that a majority of the directors then in office (or, if the board has delegated such authority, the nomination or similar committee of the board) shall nominate the remaining directors for election to the board, one of whom shall be the Issuer’s executive chairman, who is currently Mr. McGlade, or if there is no executive chairman, the Issuer’s chief executive officer.  Under the Governance Agreement, each of the Governance Shareholders has agreed to vote all shares held by it in favor of the directors nominated under the terms of the Governance Agreement and in furtherance of the removal of any directors by the BC Shareholder or the Silver Lake Shareholder under the terms of the Governance Agreement.  The Governance Agreement is filed as an exhibit hereto and the foregoing summary is qualified in its entirety by the terms thereof.

Given the terms of the Governance Agreement, the Reporting Person, collectively with the Silver Lake Shareholder and certain related parties (collectively, the “SLP Parties”) and Serafina S.A. and certain related parties (collectively, the “Serafina Parties”), may be deemed to constitute a “group” that, as of the date hereof, collectively beneficially owns approximately 81,090,825 common shares, or approximately 67.6%, of the Issuer’s outstanding common shares for purposes of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Act”), assuming the conversion of all outstanding equity awards held by Mr. McGlade that are vested or that will vest within the next 60 days.  The Reporting Person disclaims beneficial ownership of the common shares of the Issuer other than the shares reported on the cover page included herein.  Pursuant to Rule 13d-1(k)(2) under the Act, the SLP Parties and the Serafina Parties are each filing separate Schedule 13Gs with respect to the common shares of the Issuer.
