There are the following reasons for which 2:1 is inadequate for some companies:
(a) 2:1 current ratio shows that the company invests twice in the current assets compared to current liabilities to avoid the risk of default of payment. This strategy of the business is the defensive strategy.
(b) Investing a high amount in the current assets reduce the level of investment in fixed assets which increases the capacity of the company to produce more and grow more.
(c) Investing twice the amount in current assets than current assets increases the burden on the shareholders to invest more, limiting their investment opportunity.
