According to the Northern Rock Case Study, what is Forced Insolvency?

The bank is insolvent in that the current value of its assets (measured at book value) is less than the value of its liabilities; thus even if the bank were to liquidate all of its assets it would not be able to repay all depositors and other creditors

The bank is legally solvent but if, because it cannot fund its operations, it is forced to liquidate assets it could do so only at less than nominal values (fire sale) and this would make it legally insolvent (value of assets falls below those of liabilities)

The bank is legally solvent but its current funding costs (which are likely to continue) exceed the average rate of return on its assets and hence it would soon become insolvent as it would be making losses and would eventually exhaust its equity capital
