Since the working capital ratio measures current assets as a percentage of current liabilities, it would only make sense that a higher ratio is more favorable. A WCR of 1 indicates the current assets equal current liabilities. A ratio of 1 is usually considered the middle ground. It's not risky, but it is also not very safe. This means that the firm would have to sell all of its current assets in order to pay off its current liabilities.
A ratio less than 1 is considered risky by creditors and investors because it shows the company isn't running efficiently and can't cover its current debt properly. A ratio less than 1 is always a bad thing and is often referred to as negative working capital.
On the other hand, a ratio above 1 shows outsiders that the company can pay all of its current liabilities and still have current assets left over or positive working capital.
