Checked score

Outside the general model

Model not applicable to financial institutions

The Checked score measures liquidity, leverage and margins against the norms for trading and manufacturing companies. A bank, insurer or financial holding has a very different balance sheet. Those ratios and the score mean nothing here. So there is no financial strength either.

Bankruptcy probability within 12 months

The company is a financial institution: a bank, insurer or financial holding. Its balance sheet works differently from that of a trading or manufacturing company. A bankruptcy probability from the general model would mislead here.
