Note 4 - Capital adequacy

SpareBank 1 SMN utilises the Internal Rating Based Approach (IRB) for credit risk. Use of IRB imposes wide-ranging requirements on the bank’s organisational set-up, competence, risk models and risk management systems. As from 31 March 2015 the bank has received permission to apply the Advanced IRB Approach to those corporate portfolios that were previously reported under the Basic Indicator Approach. 

As of 31 December 2017 the capital conservation buffer requirement is 2.5 per cent, the systemic risk requirement is 3.0 per cent and the Norwegian countercyclical buffer is 2.0 per cent. These requirements are additional to the requirement of 4.5 per cent CET1 capital, so that the overall minimum requirement on CET1 capital is 12.0 per cent. In addition the financial supervisory authority has set a Pillar 2 requirement of 2.1 per cent for SpareBank 1 SMN, effective as from the fourth quarter of 2016. The total minimum requirement on CET1 capital is accordingly 14.1 per cent.

The countercyclical buffer increased from 1.5 per cent to 2.0 per cent with effect from 31 December 2017.

SpareBank 1 SMN has in fourth quarter 2017 reclassified two additional Tier 1 capital bonds from liabilities to equity, and the comparable figures has been restated. For further details, see note 1.

As from the fourth quarter of 2016 differentiated rates came into force for the countercyclical buffer. For exposures in other countries the countercyclical buffer rate set by the authorities in the country concerned is applied. If that country has not set a rate, the same rate as for exposures in Norway is applied unless the Ministry of Finance sets another rate. For the  fourth quarter of 2017 the parent bank is below the capital deduction threshold such that the Norwegian rate is applied to all relevant exposures. For the group, the risk-weighted countercyclical capital buffer is 2.0 per cent.

Parts of the group’s hybrid capital and subordinated debt were issued under earlier rules. This will be subject to a write-down of 40 per cent in 2016 and 50 per cent in 2017. The write-down will increase by another 10 per cent per year thereafter. As at 31 Desember 2017 the bank held hybrid capital worth NOK 450 million subject to write-down. For subordinated debt the figure was NOK 659 million.
