When it prepares the consolidated accounts the management team makes estimates, discretionary assessments and assumptions which influence the application of accounting principles. This accordingly affects recognised amounts for assets, liabilities, revenues and expenses. Last year’s annual accounts give a closer explanation of significant estimates and assumptions in Note 3 Critical estimates and assessments concerning the use of accounting principles. 

Pensions

Sparebank1 SMN Group has one pension arrangement; defined contribution plan. For a further description of the pension scheme, see note 22 in the 2019 annual report.

The group’s pension liabilities are accounted for under IAS 19R. Estimate variances are therefore directly reflected in equity capital and are presented under other comprehensive income.

It was decided to terminate the defined benefit scheme at a board meeting on 21 October 2016. Employees on this scheme transferred to the defined contribution scheme from 1 January 2017, and received a paid-up policy showing rights accumulated under the defined benefit scheme. Paid-up policies are managed by the pension fund, which has been a paid-up pension fund as from 1 January 2017. A framework agreement has been established between SpareBank 1 SMN and the pension fund which covers funding, asset management etc. In view of the responsibility still held by SpareBank 1 SMN, future liabilities will need to be incorporated in the accounts. The board of the pension fund is required to be composed of representatives from the Group and participants in the pension schemes in accordance with the articles of association of the pension fund. 

A new calculation of the Group’s pension liabilities has been carried out as per 31 December 2020: 

Investment held for sale

SpareBank 1 SMN's strategy is that ownership duse to defaulted exposures should at the outset be of brief duration, normally not longer than one year. Investments are recorded at fair value in the Parent Bank's accounts, and is classified as investment held for sale.

Losses on loans and guarantees

For a detailed description of the Bank's model for expected credit losses, refer to note 2 and 3 in the annual accounts for 2019. 

In the first quarter 2020 some changes were made in the input in the credit loss model as a result of changed expectations due to the corona situation. The crisis and the significant increase in macroeconomic uncertainty have made the assessments extra demanding. We are in the early stages of the crisis and the consequences for the bank's customers and the industries we are exposed to are difficult to estimate. The regulators have emphasized the importance of focusing on the expected long-term effects of the crisis and this has also been the bank's focus.  

In the first quarter 2020 the bank changed the assumptions for the base scenario in a negative direction. This has been continued for the rest of 2020. In the third quarter the bank's exposure to hotels and tourism, including commercial real estate with the income mainly towards this industry, is separated into a separate portfolio with its own assessments of PD and LGD courses as well as special scenarios and weighting of these to reflect this portfolio's exposure to the effects of corona. In addition, this entire portfolio is included in stage 2 or 3.

The development in the base scenario is prepared using adjustment factors where the development in the business cycle is projected by assumptions about how much the probability of default (PD) or loss of default (LGD) will increase or decrease compared to the base scenario in a five-year period. We expect increased losses related to debtors that have a demanding starting point before the crisis - typically debtors in stage 2. We have therefore chosen to increase the trajectories for PD and LGD as well as reduce expected repayments in the base scenario, especially from year 2 onwards, since this will affect expected losses mainly for debtors in stage 2. To adjust for migration into stage 2, PD and LGD estimates are also increased in the first year. No first year repayments are assumed for all portfolios in the downside scenario.

The applied scenario weighting was changed in the fourth quarter to reflect further increased uncertainty. For corporate market including offshore, as well as agriculture, the downside scenario was changed from a weighting with a 10 percent probability, to a weighting of a 20 percent probability. For retail market, the weighting of the downside scenario was changed from 10 to 15 per cent.

The effect of changes in input assumptions is shown as "Effect of changed assumptions in ECL model" in note 7. The effect is NOK 165 million for the Bank and 140 million for the Group.  

Sensitivities 

The first part of the table below show total calculated expected credit loss as of 31 December 2020 in each of the three scenarios, distributed in the portfolios retail market (RM) corporate market (CM), and offshore, travel and agriculture which adds up to parent bank. In addition the subsidiary SB 1 Finans Midt-norge is included. ECL for the parent bank and the subsidiary is summed up in th coloumn "Group".

The second part of the table show the ECL distributed by portfolio using the scenario weight applied, in addition to a alternative weighting where worst case have been doubled. If the downside scenario’s probability were doubled at the expense of the baseline scenario at the end of December 2020, this would have entailed an increase in loss provisions of NOK 207 million for the parent bank and NOK 215 million for the group.

The Tourism portfolio includes commercial real estate with more than 50% of the income from hotels and tourism companies.

In addition, an ECL provision has been included for the group for SpareBank 1 SMN Spire Finans of NOK 2 million, which is not specified in the table.

The table reflects that there are some significant differences in underlying PD and LGD estimates in the different scenarios and that there are differentiated levels and level differences between the portfolios. At group level, the ECL in the upside scenario, which largely reflects the loss and default picture in recent years, is about 80 per cent of the ECL in the expected scenario. The downside scenario gives about double the ECL than in the expected scenario. Applied scenario weighting gives about ten percent higher ECL than in the expected scenario.
