The Eurosystem central banks purchasing corporate bonds under the CSPP shall be specified in a list published on the ECB's website. The Eurosystem shall apply a specialisation scheme for the allocation of corporate bonds to be purchased under the CSPP based on the issuer's country of incorporation. The Governing Council shall allow ad hoc deviations from the specialisation scheme if there are objective considerations obstructing the scheme's implementation or if such deviations are advisable in order to achieve the CSPP's overall monetary policy objectives. In particular, each specified Eurosystem central bank shall only purchase eligible corporate bonds issued by issuers incorporated in specified Member States within the euro area. The geographical allocation of eligible corporate bond issuers' countries of incorporation in relation to the specified Eurosystem central banks shall be set out in a list published on the ECB's website.
