to keep enough highly liquid assets to cover its net liabilities for the next 10 days to guard against severe liquidity stress

to keep enough highly liquid assets to cover its net liabilities for the next 30 days to guard against severe liquidity stress

to keep enough highly liquid assets to cover its net liabilities for the next 60 days to guard against severe liquidity stress

to retain enough liquidity to cover its assets against severe default risk
