If a reporting institution uses a book quarter that differs from a calendar quarter in which the three-month periods do not coincide with calendar quarters, then the book quarters may be used for this reporting unless there are significant transactions in a month that fall outside the reference calendar quarter.
DNB nevertheless stresses the importance to report on the basis of calendar quarters. If this is not possible, different quarters may be reported, with the last month of the book quarter leading for the calendar quarter. For example, if the book quarter ends in April, DNB considers this to be the second quarter. Significant transactions must be reported in the correct calendar quarter.
Examples of application:
- Nov, Dec, Jan is Quarter 1
- Dec, Jan, Feb is Quarter 1
- Jan, Feb, Mar is Quarter 1 (regular calendar quarter)
