(69)As the restriction or the suspension of the distribution of dividends and other bonuses would affect, even on a temporary basis, the rights of shareholders and other subordinated creditors, supervisory authorities should duly take into account the principles of proportionality and necessity when taking such measures. Supervisory authorities should also ensure that none of the measures adopted entails disproportionate adverse effects on the whole or parts of the financial system in other Member States or in the Union as a whole. In particular, supervisory authorities should only restrict capital distributions within an insurance and reinsurance group in exceptional circumstances, and when duly justified to preserve the stability of the insurance and reinsurance market and of the financial system as a whole.
