Financial Ratios

Current Ratio – current assets divided by current liabilities, which indicates the company’s ability to repay its short-term liabilities with short-term assets. The current ratio in all periods was adversely affected by the fact that Chevron’s inventories are valued on a last-in, first-out basis. At year-end 2014, the book value of inventory was lower than replacement costs, based on average acquisition costs during the year, by approximately $8.1 billion.

Interest Coverage Ratio – income before income tax expense, plus interest and debt expense and amortization of capitalized interest, less net income attributable to noncontrolling interests, divided by before-tax interest costs. This ratio indicates the company’s ability to pay interest on outstanding debt. The company’s interest coverage ratio in 2014 was lower than 2013 and 2012 due to lower income.

Debt Ratio – total debt as a percentage of total debt plus Chevron Corporation Stockholders' Equity, which indicates the company’s leverage. The company's debt ratio in 2014 was higher than 2013 and 2012 as the company took on more debt to finance its ongoing investment program, partially offset by a higher stockholders' equity balance.
