The OECD and the G20 have decided to encourage the automatic exchange of information (AEI) to combat tax evasion worldwide. On 19 November 2014, Switzerland became the 52nd nation to sign the Multilateral Competent Authority Agreement (MCAA), which defines the principles of AEI. Consultation regarding the ratification of the agreement and the draft federal law for implementation ends on 21 April 2015. The central question for Swiss private banks is: to whom will Switzerland grant AEI?
