On July 12, 2016, pursuant to the terms of an Agreement and Plan of Merger, dated as of March 20, 2016 (the “Merger Agreement”), by and among IHS, Markit Ltd., a Bermuda company (“Markit”), and Marvel Merger Sub, Inc., a Delaware corporation and an indirect wholly-owned subsidiary of Markit (“Merger Sub”), Merger Sub merged with and into IHS, with IHS surviving such merger as an indirect wholly-owned subsidiary of Markit (the “Merger”). In connection with the closing of the Merger, “Markit Ltd.” changed its name to “IHS Markit Ltd.”

At the effective time of the Merger (the “Effective Time”), each share of Class A common stock, par value $0.01 per share, of IHS (the “Common Stock”) (other than shares of Common Stock held in treasury) was converted into the right to receive 3.5566 (the “Exchange Ratio”) fully paid and nonassessable common shares of the Combined Company (the “Markit Common Shares”).

In addition, at the Effective Time, each equity award of IHS outstanding immediately prior to the Effective Time was converted into equity awards of the Combined Company in accordance with the Merger Agreement.

The foregoing description of the effects of the Merger and the Merger Agreement, and the transactions contemplated thereby, does not purport to be complete and is subject to, and qualified in its entirety by reference to, the full text of the Merger Agreement attached as Exhibit 2.1 to IHS’s Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) on March 21, 2016, and is incorporated herein by reference.

Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

In connection with the closing of the Merger, on July 12, 2016, IHS notified The New York Stock Exchange (“NYSE”) that the Merger had been completed, and requested that NYSE suspend trading of the Common Stock on NYSE and remove the Common Stock from listing on the NYSE, in each case, prior to market open on July 13, 2016. The Markit Common Shares have been approved for listing on The NASDAQ Global Select Market (“NASDAQ”) under the ticker symbol “INFO” and will begin trading on July 13, 2016. IHS has also requested that NYSE file a notification of removal from listing of the Common Stock on Form 25 with the SEC pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Additionally, IHS intends to file a Form 15 with the SEC to terminate the registration of the Common Stock under the Exchange Act and suspend its reporting obligations under Sections 13 and 15(d) of the Exchange Act.
