The accounting statistics for the financial institutions is based on current accounting regulations for financial institutions.
Breaches may therefore occur in connection with changes in accounting legislation and in the regulations applicable to the
financial institutions. Structural changes like new companies, mergers and spin-offs, with portfolio movements as one consequence,
may also lead to breaches in the time series.
International Financial Reporting Standard (IFRS)
The new accounting standard IFRS is an example of a change that will cause breaches in the time series in the periods to come.
In 2009/2010 all reporting companies must, in one way or another, report according to the IFRS standard, and data may then
be fully comparable again. However, the IFRS standard will lead to larger fluctuations in the data because of the more extensive
use of fair value in the accounting. The comparison of the reported data with the companies' official accounts is also challenging
because the IFRS standard does not require a specific presentation of the accounts, as the traditional Norwegian accounting
standard does.
Regulation on loans
The IFRS-adapted regulation on loans was introduced 1. January 2005. It lead to a small change in the measuring of the value of loans and guaranties in the accounting
data and thereby to a small breach in the time series for loans and loan loss provisions. There were also a breach in the
time series on loans in 1992 due to changed accounting rules.
Changes in the presentation of the statistics
Credit lines secured on dwellings became a new specification from January 2006. As a consequence the numbers for repayment
loans secured on dwellings and credit lines, working capital facility and consumer credit were reduced.
Structural changes
There are several mergers, spin-offs and new companies being started every year. Many of these structural changes have no
significant impact on the statistics, while others leads to major breaches in the time series. When the latter is the case,
it will be commented upon in this section.
Portfolio movements
The introduction of IFRS, the regulation on loans and the structural changes mentioned, has lead to portfolio movements especially
between banks and mortgage companies. This gives breaches in the time series and needs to be taken into consideration when
interpreting the data.
New institutional sector classification
The Norwegian institutional sector classification was revised on 1 January 2012 in line with the international classification.
This change entails a break in the statistics for the accounting statistics for financial corporations from March 2012.
As a result of the new classification, some enterprises that were previously classified as non-financial enterprises are now
classified as financial enterprises. These enterprises are therefore no longer a part of the statistics of industry loans.
The industry of professional and financial services is most affected, since many of the enterprises, which were previously
classified as non-financial enterprises were also likely to be a part of the industry of professional and financial services.
New industry classification
The industry classification in the financial statistics changed in May 2009 when Statistics Norway introduced a new version
of the Norwegian industry classification, SIC2009 . This leads to a more detailed classification and enables us to better
analyse the development in important industries. However, the change also made comparisons of industrial loans before and
after May 2009 difficult for some of the industries.
