known as Single Malt). The Irish media picked up the article, but when an Irish MEP notified the then Finance Minister, Michael Noonan, he was told to "Put on the green jersey". A November 2017 report by Christian Aid, titled Impossible Structures, showed how quickly the Single Malt BEPS tool was replacing the Double Irish. The report detailed Microsoft's and Allergen's schemes and extracts from advisers to their clients. In September 2018, The Irish Times revealed that U.S. medical device manufacturer Teleflex, had created a Single Malt scheme in July 2018, and reduced their corporate tax rate to circa 3%; and that the Irish State were keeping the matter, "under consideration". In November 2018, the Irish Government amended the Ireland–Malta tax treaty to prevent the Single Malt BEPS tool being used between Ireland and Malta (it can still be used with the UAE for example). On the same day the closure was announced, LinkedIn in Ireland, identified as a user of the Single Malt tool in 2017, announced in filings that it had sold a major IP asset to its parent, Microsoft (Ireland). In July 2018, it was disclosed in the Irish financial media that Microsoft (Ireland) were preparing a restructure of their Irish BEPS tools into a CAIA (or Green Jersey) Irish tax structure.

In September 2009, the Commission recommended that the Irish State provide capital allowances for the acquisition of intangible assets, creating the Capital Allowances for Intangible Assets (CAIA) BEPS tool. Whereas the Double Irish and Single Malt BEPS tools enable Ireland to act as a confidential "Conduit OFC" for rerouting untaxed profits to places like Bermuda (i.e. it must be confidential as higher-tax locations would not sign full tax treaties with locations like Bermuda), the CAIA BEPS tool, enables Ireland to act as the "Sink OFC" (i.e. the terminus for untaxed profits, like Bermuda). CAIA uses the accepted tax concept of providing capital allowances for the purchase of physical assets. However, Ireland turns it into a BEPS tool by providing the allowances for the purchase of intangible assets, and particularly intellectual property assets; and critically, where the owner of the intangible assets is a "connected party" (e.g. a Group subsidiary, often located in a
