 Once the XBRL file has passed the above four validations, it will be queued for validation
against the EBA Taxonomy. The length of time it will be queued will depend on the
number of institutions uploading and validating XBRL files on the ONR system at the same
time.

 Once the XBRL file has begun the validation against the EBA Taxonomy, the status of the
file will display as ‘Processing’ on the screen below.
Note: The average time to load a file may vary on the live system depending on the number
of Institutions using the system at the same time.

Variance Analysis Functionality
The Online Reporting System now contains a ‘Variance Analysis’ solution which will compare CRD IV
returns period on period and require institutions to explain variances that exceed a certain
percentage and threshold.
The following are the COREP templates which are covered by Variance Analysis:
COREP




CA01.00 OWN FUNDS
CA02.00 OWN FUNDS REQUIREMENTS
CA03.00 CAPITAL RATIOS
CA04.00 MEMORANDUM ITEMS
An explanation is required for the following:



Where there is a positive or negative variance of greater than or equal to 20%, then an
explanation must be provided. The 20% variance applies to all of the above templates.
An explanation is required for any variance from Zero (increase or decrease).
Variances in Percentages will be treated the same as amounts and will follow the same rules
as above.
The Variance Analysis functionality is going live on the 29th July 2014. The first period to which it will
relate will be the June 2014 quarter-end which will be compared to the previous March 2014
quarter-end for the above COREP templates.
The returns for the previous reporting period must be signed-off before the returns for the
subsequent reporting period and the variance analysis explanations template can be finalised and
signed-off.
The following are the procedures for accessing these screens on the Online Reporting System.
