Accounting Interview Questions

The three primary financial statements are the Income Statement, the Balance Sheet, and the Cash Flow Statement. The Income Statement measures a company's financial performance and profitability over a defined period, such as a quarter or a fiscal year. It begins with Revenue, subtracts the cost of goods sold to reach Gross Profit, and then deducts operating expenses, depreciation, amortisation, interest, and taxes to arrive at Net Income, which represents the bottom-line earnings available to shareholders. The Balance Sheet provides a structural snapshot of a company's financial position at a single point in time. It is governed by the accounting equation where Assets must equal Liabilities plus Shareholders' Equity. Assets reflect the economic resources owned or controlled by the company, such as cash, inventory, accounts receivable, and property, plant, and equipment. Liabilities represent obligations to third parties, including accounts payable and debt obligations. Shareholders' Equity represents the residual value belonging to the owners, comprising share capital and retained earnings. The Cash Flow Statement tracks the actual cash generated and consumed by the company over a period, eliminating the non-cash distortions introduced by accrual accounting. It begins with Net Income from the Income Statement, adds back non-cash expenses like depreciation, and adjusts for changes in working capital to calculate Cash Flow from Operating Activities. It then incorporates Cash Flow from Investing Activities, which includes capital expenditures or asset sales, and Cash Flow from Financing Activities, which captures equity raises, debt issuances, dividends, and debt repayments. The final net change in cash modifies the cash balance on the Balance Sheet.

If I could only choose a single financial statement to evaluate a company, I would select the Cash Flow Statement. The primary reason is that cash flow provides an objective, unvarnished look at a company's actual liquidity and operational health, whereas the Income Statement can be heavily distorted by non-cash revenue recognition policies, aggressive depreciation assumptions, and management judgements under accrual accounting rules. A business can report highly profitable Net Income on paper while simultaneously burning through its cash reserves and sliding toward operational insolvency due to poor working capital management or excessive capital expenditure requirements. The Cash Flow Statement immediately strips away these non-cash distortions. By looking at the operational section, I can verify if the core business activities are genuinely self-sustaining and generating cash. Furthermore, corporate valuation in investment banking and private equity is fundamentally rooted in the present value of a company's future free cash flows. The Cash Flow Statement directly reveals the capital expenditures required to maintain the business and the net cash left over to service debt obligations or distribute to equity holders. If I need to assess credit risk or investment viability in a limited window, tracking actual cash inflows and outflows provides the most reliable foundation.

On the Income Statement, an incremental depreciation charge of 10 increases operating expenses, which reduces operating income and pre-tax income by 10. With a 20 per cent tax rate, the corporate tax expense falls by 2, meaning that Net Income decreases by 8. Next, we move to the Cash Flow Statement. We start at the top of the operating section with Net Income, which is down by 8. Because depreciation is a non-cash expense, we add back the full 10 of depreciation. This means Net Cash from Operating Activities increases by 2. There are no changes in Cash Flow from Investing Activities or Cash Flow from Financing Activities, so the net change in cash at the bottom of the statement is an increase of 2. Finally, we link this to the Balance Sheet. On the Assets side, Cash is up by 2 because of the net cash generated from the tax shield. However, Property, Plant, and Equipment decreases by 10 due to the incremental depreciation. Therefore, net total Assets decrease by 8. On the Liabilities and Shareholders' Equity side, there are no changes to Liabilities or Share Capital, but Retained Earnings decreases by 8 because the Net Income drop of 8 flows directly into equity. As a result, total Assets are down by 8, Liabilities and Equity are down by 8, and the Balance Sheet balances perfectly.

When a company purchases GBP 100 (USD 130) of inventory on credit, there is no immediate impact on the Income Statement. This is because under accrual accounting rules, inventory costs are not recognised as an expense until the corresponding revenue is generated through a sale. The transaction has not triggered a Cost of Goods Sold charge yet. On the Cash Flow Statement, there is also no net impact on cash. In the operating cash flow section, the increase in inventory represents a working capital outflow of GBP 100 (USD 130). However, because the inventory was purchased on credit, Accounts Payable increases by GBP 100 (USD 130), which represents a working capital inflow. These two adjustments directly cancel each other out, leaving Net Cash from Operating Activities and the net change in cash completely unchanged at zero. On the Balance Sheet, the adjustments occur entirely within asset and liability accounts. Under Assets, Inventory increases by GBP 100 (USD 130). Under Liabilities, Accounts Payable increases by GBP 100 (USD 130) because the company owes this amount to its suppliers. Shareholders' Equity remains completely unchanged because Net Income did not move. Total Assets are up by GBP 100 (USD 130), Liabilities are up by GBP 100 (USD 130), and the Balance Sheet balances.

When a customer pays GBP 50 (USD 65) of an outstanding account receivable, there is no impact on the Income Statement. The revenue associated with this transaction was already recognised and taxed in a prior period when the sale actually occurred, in line with accrual accounting principles. On the Cash Flow Statement, Net Income at the top of the operating section is unchanged at zero. However, we must account for the change in working capital. A decrease in Accounts Receivable is treated as a source of cash, adding GBP 50 (USD 65) to Cash Flow from Operating Activities. Since there are no adjustments in the investing or financing sections, the net change in cash at the bottom of the statement is an increase of GBP 50 (USD 65). On the Balance Sheet, the transaction is an asset swap that leaves the total balances unchanged. Under Assets, Cash increases by GBP 50 (USD 65) due to the customer collection. Concurrently, Accounts Receivable decreases by GBP 50 (USD 65) because that specific customer invoice has been settled. Net total Assets remain unchanged. Because there was no movement in Net Income, Retained Earnings and total Liabilities remain unchanged as well. The statement balances cleanly because the positive and negative adjustments occurred entirely on the asset side.

Net Working Capital is structurally defined as operating current assets, such as Accounts Receivable and Inventory, minus operating current liabilities, such as Accounts Payable and Accrued Expenses. Cash and short-term debt are intentionally excluded from this calculation because they relate to the financing and capital structure of the business rather than its pure operations. For a financial analyst or private equity investor, working capital is a critical metric because it represents the hidden cash consumption of a business. A company can show strong revenue growth on its Income Statement, but if it has to offer generous payment terms to customers, its Accounts Receivable will spike. If it must store massive amounts of inventory to avoid stockouts, cash becomes trapped on the Balance Sheet. An increase in Net Working Capital represents a direct cash outflow on the Cash Flow Statement, which reduces the company's Free Cash Flow. Conversely, if a business can extend its payables to suppliers while collecting cash rapidly from customers, it operates with a highly efficient or even negative working capital structure, which unlocks cash that can be used to pay down debt or reinvest in expansion.

Depreciation is added back on the Cash Flow Statement because it represents a non-cash expense. When a company purchases a major capital asset, such as a factory or equipment, the actual cash outflow is recorded entirely within Cash Flow from Investing Activities under Capital Expenditures at the time of purchase. Rather than expensing that massive cash layout all at once on the Income Statement, accounting rules require the company to allocate that cost over the useful life of the asset via depreciation. As a result, the annual depreciation charge listed on the Income Statement reduces pre-tax income and Net Income, but no actual cash leaves the bank account during that specific year. Since the Cash Flow Statement begins with Net Income at the top of the operating section, we must add back the full depreciation charge to reverse the non-cash reduction. This ensure that the cash flow statement accurately reflects the actual cash generated by operations, leaving only the real cash benefit of the depreciation tax shield in place.

The fundamental difference between enterprise value and equity value lies in which group of investors the value belongs to. Enterprise Value represents the total economic value of the underlying operational business, independent of how it is financed. It is the value available to all capital providers, including secured debt holders, unsecured bondholders, preferred shareholders, and common equity holders. It is often described as the theoretical purchase price of the entire business before capital structure restructuring. Equity Value, by contrast, represents the residual value of the company available exclusively to common shareholders. It is the value that remains after all non-equity obligations, such as debt and preferred stock, have been fully satisfied. To bridge the two, Enterprise Value is calculated by taking Equity Value, adding total debt, preferred stock, and non-controlling interests, and then subtracting cash and cash equivalents. Cash is subtracted because it is a non-operating asset that could theoretically be used to pay down a portion of the debt immediately, reducing the net cost of acquiring the operational business core.

When a company issues GBP 100 (USD 130) of common equity to repay GBP 100 (USD 130) of financial debt, its Enterprise Value remains completely unchanged. We can prove this by looking at both the mathematical bridge and the underlying economic theory. Mathematically, the formula for Enterprise Value is Equity Value plus Debt minus Cash. By issuing GBP 100 (USD 130) of new stock, the company's Equity Value increases by exactly GBP 100 (USD 130). Simultaneously, the company uses that capital to pay off GBP 100 (USD 130) of debt, which reduces the Debt component of the formula by GBP 100 (USD 130). The cash balance is unchanged because the cash raised from equity was immediately deployed to extinguish the debt. Therefore, the positive adjustment to equity value and the negative adjustment to debt cancel each other out completely, leaving Enterprise Value unchanged. From an economic perspective, Enterprise Value measures the value of the company's core operating assets and cash-generative power. This transaction is a purely financial restructurings; it does not change the company's factories, its customer contracts, its pricing power, or its operational revenues. It simply alters how those operating assets are financed, shifting the capital mix away from debt and toward equity. Aside from minor secondary effects like a reduced tax shield from lower interest expenses, the baseline Enterprise Value remains constant.
