(10)Whilst many countries have adopted IFRS directly into their national GAAP, other countries are converging national GAAP to IFRS over a period of time. In the light of this, it is appropriate, for a maximum two year transitional period, also to exempt such third country issuers from restating historical financial information or (as the case may be) from providing a narrative description of differences, provided that the national authority responsible has made a public commitment to this effect and established a work programme. In order to ensure that the exemption is available only in cases where these conditions are satisfied, the third country issuer should be required to provide evidence that satisfies the competent authority that the national authority has made a public statement and established a work programme. To ensure consistency within the Community, CESR should coordinate the competent authorities' assessment as to whether those conditions are satisfied in respect of individual third country GAAPs.
