Bank of Ireland is to change its fiscal year end from 31 March to 31 December, bringing the bank's financial calendar into line with other banks.
This means the next Annual Report and Accounts to be published by the Bank shall cover a period of nine months from 1 April 2009 to 31 December 2009.
The bank had been due to issue an Interim Management Statement today, but the change in date means that the bank is now technically in a closed period.
Changing its business year-end will mean Ireland's biggest bank by market value won't have a so-called 'closed period' in April and May pending its full-year results, which could give it more flexibility to approach the markets for extra capital.
Bank of Ireland is due to announce its preliminary results for the nine months ended 31 December 2009 at the end of March.
