Current Ratio

Both inputs come straight from the classified balance sheet. Current assets typically comprise cash and equivalents, short-term marketable securities, trade receivables, inventory and prepaid expenses. Current liabilities gather accounts payable, accrued expenses, short-term borrowings, the current portion of long-term debt, unearned revenue and taxes payable. The classification test is time-based: an item is current if it is expected to be realised, sold, consumed or settled within one year or within the company's normal operating cycle, whichever is longer. That second clause matters for shipbuilders, distillers and construction firms, where inventory legitimately sits current despite a multi-year cycle.

The arithmetic is simply total current assets divided by total current liabilities, expressed as a multiple rather than a percentage. A result of 1.4 means the firm holds 1.40 of short-dated assets for every 1.00 of short-dated obligations.

The ratio treats every current asset as equally liquid, which they are not. Analysts therefore read it alongside the quick ratio, which strips inventory and prepaid expenses out of the numerator, and the cash ratio, which retains only cash, equivalents and short-term marketable securities. A wide gap between the current and quick ratios signals that the apparent cushion is inventory-dependent, and inventory converts to cash only after a sale and then a collection period.

The cash conversion cycle supplies the missing dynamic dimension. A firm with days of inventory on hand plus days of sales outstanding well below its days of payables outstanding generates cash before it must pay suppliers, and can operate safely with a low or even sub-1.0 static ratio. Conversely, a high ratio built on slow-moving stock and ageing receivables can mask a genuine funding problem.

Because the ratio is a point-in-time snapshot, it is sensitive to both policy and calendar. Inventory costing is the classic case: under US GAAP, a firm using LIFO in a rising-price environment reports lower inventory than an economically comparable FIFO firm, depressing the numerator. Adding the LIFO reserve back to inventory places the company on a FIFO basis and raises the ratio, a standard comparability adjustment.

Classification decisions matter equally. Reclassifying a maturing bond into the current portion of long-term debt, drawing on a revolver at year-end, or the treatment of a refinancing arranged after the reporting date can swing the ratio without any change in economics. Retailers and other seasonal businesses often set fiscal year-ends at the trough of the working capital cycle, when inventory has been sold down and payables settled, flattering the balance sheet relative to a mid-year reading.

Candidates should be able to compute the ratio from a classified balance sheet, decompose an unexpected movement into its inventory, receivable and payable drivers, and rank a company against peers and its own trailing history. A frequently tested skill is directional: settling an account payable with cash reduces the numerator and denominator by the same amount, which raises the ratio if it began above 1.0 and lowers it if it began below 1.0. Buying inventory on credit does the reverse, pulling the ratio toward 1.0 from either direction.

The ratio also carries contractual weight. Loan agreements commonly impose a minimum current ratio covenant, so a breach can accelerate debt and convert long-term obligations into current ones, compounding the deterioration. Recognising that feedback loop, rather than reciting a target multiple, is what distinguishes competent analysis.
