The financial ratios are important because they can tell you a really informative story for the performance and the position of the company. They basically offer a framework that you can use to assess whether the company has good margins, whether it is solvent, if it generates enough cash, if it will be able to meet its obligations as they fall due and whether the financial leverage of the firm is within an acceptable range.
The best part is that you can compare this image with other financial years (its own past) as well as use other companies in the same industry as a benchmark!
