II. Functional Classification: This classification reflects the functional need and the purpose of calculating ratio. The basic rationale to compute ratio is to ascertain liquidity, solvency, financial performance and profitability of a business. Consequently, the Functional Classification classifies various accounting ratios as:

a. Liquidity Ratio: These ratios are calculated to determine short term solvency.

b. Solvency Ratio: These ratios are calculated to determine long term solvency.

c. Activity Ratio: These ratios are calculated for measuring the operational efficiency and efficacy of the operations. These ratios relate to sales or cost of goods sold.

d. Profitability Ratio: These ratios are calculated to assess the financial performance and the financial viability of the business.
