Subsequent Events [Abstract]
Subsequent Event	Subsequent Event On January 27, 2021, we issued an announcement (the “Rule 2.7 Announcement”) pursuant to Rule 2.7 of the United Kingdom City Code on Takeovers and Mergers (the “Code”) disclosing the terms of a recommended cash offer to acquire the entire issued and to be issued ordinary share capital of Scapa Group plc, a company incorporated in England and Wales (“Scapa”) and listed on the AIM market of the London Stock Exchange (the “Offer”). Under the terms of the Offer, Scapa shareholders will receive £2.10 in cash for each ordinary share of Scapa (together, the “Scapa Shares”), which values the entire issued and to be issued ordinary share capital of Scapa at approximately £402.9 million (or approximately $551.9 based on an exchange rate of US$1.37:£1). The Offer is intended to be effected by means of a scheme of arrangement (the “Scheme”) under Part 26 of the United Kingdom Companies Act 2006, as amended (the “Companies Act”). SWM Bidco reserves the right to elect (with the consent of the U.K. Panel on Takeovers and Mergers (the “Panel”) and subject to the terms of the Co-operation Agreement described below) to implement the Offer by way of a Takeover Offer (as such term is defined in Part 28 of the Companies Act) as an alternative to the Scheme. The Offer will be subject to conditions and certain further terms, including, among others, (i) the Scheme becoming effective no later than 11:59 p.m. (London time) on July 27, 2021 or such later date as agreed by the parties (the “Long Stop Date”), (ii) the approval of the Scheme by a majority in number of Scapa shareholders present and voting (and entitled to vote), either in person or by proxy, at a general meeting of Scapa shareholders (including any adjournment, postponement or reconvention thereof) (the “General Meeting”) representing at least 75% in value of the Scapa Shares voted by such shareholders; (iii) the passing of the special resolution or resolutions to be proposed by Scapa at the General Meeting in connection with, among other things, the amendment of the articles of association of Scapa and such other matters as may be necessary to implement the Scheme; (iv) the sanction of the Scheme by the High Court of Justice in England and Wales; and (v) the receipt of certain merger control and regulatory approvals or the lapse of relevant periods or notifications thereunder. The conditions to the Offer are set out in full in the Rule 2.7 Announcement. Subject to the satisfaction or waiver of all relevant conditions, it is expected that the Scheme will become effective during the second quarter of 2021. On January 26, 2021, in anticipation of our announcement of our offer to acquire Scapa Group we entered into a currency forward contract with a major financial institution. The terms of the contract provide for an exchange of a notional amount of GBP 439 million for USD, calculated using the contract rate as applicable at the settlement date, which will be on or before the “Long Stop Date” as it relates to the scheme. The currency forward contract will be recognized at fair value in our consolidated financial statements with subsequent changes in the fair value of the instrument recognized in earnings. On February 10, 2021 we amended our existing Credit Agreement to provide for, among other things an additional Term Loan Facility “Term Loan B” in the amount of $350 million and a temporary increase in our Maximum Net Debt/EBITDA ratio to 5.5x. This ratio will decrease over the course of 24 months, returning to 4.50x effective as of June 30, 2023.
