Financial Statements, Cash Flows, and Working Capital

A business can make all the sales in the world and still run out of cash. That is why simply knowing a firm’s profit is not enough — you need to understand where the money comes from, where it is tied up, and where it actually flows. This chapter teaches you to read the three main financial statements and find the cash story hidden inside them.

The Big Picture#

Every company, whether a neighbourhood bakery or a multinational corporation, tells its financial story through three main reports: the balance sheet, the income statement, and the statement of cash flows. Together they answer one simple question: Is the business creating value that can be turned into cash for those who funded it? By the end of this chapter you will not only understand what each statement says — you will know how to link them together and calculate the free cash flow that is the true reward for investors.

The Balance Sheet: A Snapshot of What We Own and Owe#

A balance sheet is exactly what it sounds like — it balances. On one side you list everything the firm owns (its assets), and on the other side you show who paid for those things: either creditors (liabilities) or the owners (shareholders’ equity). This gives us the basic rule that must always hold:

Think of it as a photo taken at a single moment — usually the last day of the reporting period. It is not a movie; it shows a single moment in time. Every transaction the firm makes changes at least two items so that the equation always holds.

Asset: Anything the firm owns that has value and can generate future economic benefits — cash, inventory, buildings, patents, money owed by customers.

Liability: An obligation to pay someone else. It could be a bank loan, a bond, or an unpaid supplier invoice.

Shareholders’ Equity: The owners’ leftover claim after all liabilities are paid. It is the book value of what shareholders have invested plus all profits kept in the business.

Liquidity — How Fast Can It Become Cash?#

Not all assets are created equal. A delivery van sitting in the parking lot is valuable, but if you urgently need to pay wages, that van won’t help you today. Liquidity is the speed and ease with which an asset can be converted to cash without losing much value.

• Cash is perfectly liquid.
• Accounts receivable (money customers owe you) will become cash soon, so it is quite liquid.
• Inventory is less liquid — you have to sell it first.
• Buildings and machinery are highly illiquid.

Why does liquidity matter? Because firms with high liquidity can pay bills on time and survive unexpected hard times. However, liquid assets usually earn very low returns (cash earns almost nothing), so managers face a trade‑off between safety and profitability.

Debt vs. Equity — Two Very Different Partners#

When a firm raises money, it can either borrow it (debt) or sell pieces of ownership (equity). The difference is important:

• Debt gives the lender a legal right to fixed payments — interest and principal — regardless of whether the firm is booming or struggling. If the firm fails, debt holders stand first in line to get paid from the sale of assets.
• Equity holders are owners. They get whatever is left after everyone else has been paid. That “leftover” can be enormous if the company thrives or zero if it fails. In exchange for that risk, equity holders control the company through voting rights.

This is why we say debt is cheaper for the firm (interest is tax‑deductible and the required return is lower because it is safer) but riskier — too much debt can drag a company into bankruptcy.

Book Value vs. Market Value — The Numbers vs. Reality#

The balance sheet records assets at their historical cost minus depreciation — this is the book value. But what could you actually sell that asset for today? That’s the market value.

Imagine a factory purchased twenty years ago for $10 million, now fully depreciated to a book value of zero. That factory might still be worth $15 million if someone would buy it. Conversely, a brand‑new piece of equipment might be on the books at $1 million but be worth far less if the technology is already obsolete.

For shareholders’ equity, the gap can be enormous. The balance sheet shows only what came in from share sales plus retained profits — it says nothing about the value the market places on future growth. So a company’s market capitalisation (share price × number of shares) often bears little resemblance to its book equity. When we talk about the value of a firm, we almost always mean its market value.

📝 Section Recap: The balance sheet balances assets against the claims of creditors and owners. Liquidity, the mix of debt and equity, and the difference between book and market values are all important for checking the financial health and true worth of a firm.

The Income Statement: Measuring Profit Over a Period#

If the balance sheet is a photograph, the income statement (also called the statement of comprehensive income) is a video — it records what happened over a period of time, such as a quarter or a year. Its purpose is to measure how much wealth the company created from its operations.

The basic structure is:

Revenue
– Cost of goods sold
= Gross profit
– Selling, general & administrative expenses
– Depreciation
= Operating profit, also called **Earnings Before Interest and Taxes (EBIT)**
– Interest expense
= Pretax profit
– Taxes
= Net income

Revenue: The total value of goods and services sold during the period, whether or not the cash has been received yet.

Net income: The “bottom line” — profit after all expenses, including depreciation, interest, and taxes.

Two things jump out immediately: not all expenses involve actual cash outflows, and profit is not the same as cash.

Non‑Cash Items — Depreciation and Deferred Taxes#

The most common non‑cash charge is depreciation. When a firm buys a long‑lived asset like a machine, it does not deduct the entire cost in one year. Instead, it spreads that cost over the asset’s useful life through depreciation expense. So each year the income statement shows a deduction for depreciation, but no cash leaves the building that year — the cash left when the asset was originally purchased.

Deferred taxes are another non‑cash item. Tax rules often allow firms to accelerate depreciation for tax purposes, which reduces taxes paid now compared to what the income statement reports. The difference creates a deferred tax liability on the balance sheet, and the adjustment flows through the income statement without involving immediate cash.

Why are these important? Because if you simply looked at net income, you would underestimate the actual cash the business generates. Later we will add back non‑cash charges to convert profit into cash flow.

📝 Section Recap: The income statement shows revenue minus expenses over a period to arrive at net income. Non‑cash items like depreciation mean that profit and cash flow are rarely the same number, so we must adjust net income to see real cash generation.

Net Working Capital: The Short-Term Fuel#

Running a business consumes cash even before a single sale is made. You need inventory on the shelves, and you often let customers pay later. At the same time, you get a little breathing room because you can delay paying your own suppliers. The difference between these short‑term assets and short‑term liabilities is called net working capital (NWC).

Net Working Capital (NWC): Current assets (cash, receivables, inventory) minus current liabilities (payables, short‑term debt). It represents the cash tied up in the day‑to‑day operations of the firm.

The equation:

When a firm grows, it typically needs more inventory and extends more credit to customers, so net working capital increases. That increase is an investment — it uses cash that could otherwise go to investors. Changes in NWC are an important piece of the cash flow puzzle.

Change in NWC: The difference between NWC at the end of a period and NWC at the beginning. A positive change means the firm invested more cash in its operations; a negative change frees up cash.

Tracking the change is simple: if NWC at the start of the year was $500,000 and at the end it is $600,000, the firm invested an additional $100,000 of its cash into working capital.

📝 Section Recap: Net working capital is the cash a business needs to keep operating day to day. When working capital grows, it absorbs cash; when it shrinks, it releases cash, directly affecting the amount available to creditors and shareholders.

Cash Flow: Where Does the Money Actually Go?#

Now we arrive at the heart of corporate finance: cash flow. While net income tells a story of profitability, cash flow tells the story of money moving in and out — and only cash can pay dividends, repay loans, or fund new investments. There is a simple rule that ties everything together.

The Financial Cash Flow Identity#

No matter how complex a firm is, every dollar of cash generated from its assets must end up in one of two pockets: either it goes to the people who lent the firm money (creditors) or to the people who own it (shareholders). This is the cash flow identity:

This identity is not a theory; it is an identity — it must always hold, in the same way that what you spend must equal where the money came from. Let us break down each piece.

Cash Flow from Assets — The Total Pot#

Cash flow from assets is the cash the firm’s operations throw off after paying for all necessary investments. It has three ingredients:

• Operating cash flow (OCF): The cash generated by making and selling the firm’s products. It is net income before interest, plus depreciation and other non‑cash items, minus taxes. Why before interest? Because we want to see the cash the whole firm (assets) produces, independent of how it is financed.

• Capital spending (CapEx): The net cash spent on long‑lived assets like property, plant, and equipment. It is the change in net fixed assets plus depreciation.

• Additions to net working capital: The cash tied up in growing the business, as we saw earlier.

Putting it all together:

Think of it this way: from all the cash the business brings in (OCF), we first pay for the new machinery and buildings we need (capital spending), and we set aside cash for the extra inventory and receivables (change in NWC). What remains is free to be distributed.

Cash Flow to Creditors and Shareholders#

• Cash flow to creditors: Interest paid to lenders minus any net new borrowing. If the firm borrows more than it repays, cash flows in from creditors, so this number can be positive or negative.

• Cash flow to shareholders: Dividends paid minus net new equity raised. Again, if the company issues new shares, cash comes in from shareholders.

Free Cash Flow — The Investor’s Prize#

When analysts speak of free cash flow (FCF), they are really talking about cash flow from assets — the cash that is available to distribute to all providers of capital after the firm has made the investments needed to sustain and grow its operations. It is the final scoreboard for value creation.

Free Cash Flow: The cash a firm generates from its assets that can be paid out to creditors and shareholders without harming the company’s ability to operate and grow.

Because free cash flow does not depend on how the firm is financed (that is captured on the right‑hand side of the identity), it is the clearest measure of a firm’s capacity to generate wealth. Investors value a company based on the present value of its expected future free cash flows.

📝 Section Recap: The cash flow identity shows that every dollar from assets flows either to creditors or to shareholders. By calculating operating cash flow, subtracting capital spending and changes in NWC, we arrive at free cash flow — the cash truly available for distribution.

The Statement of Cash Flows: Tying It All Together#

Public companies are required to present a statement of cash flows. This statement takes the balance sheet and income statement and reorganises all of the cash movements into three buckets, making it easy to see exactly where cash came from and where it went. The three buckets are:

• Operating activities: Cash flows directly related to producing and selling goods and services. This includes cash received from customers and cash paid to suppliers and employees. It also includes interest paid and taxes paid.

• Investing activities: Cash flows from buying or selling long‑term assets — property, plant, equipment, and investments in other companies. When a firm buys a new factory, it shows up here as a cash outflow.

• Financing activities: Cash flows to and from the firm’s owners and lenders — issuing or repaying debt, issuing or buying back shares, and paying dividends.

The statement of cash flows can be prepared using either the direct method (listing actual cash receipts and payments) or the indirect method (starting with net income and adjusting for non‑cash items and changes in working capital). Most firms use the indirect method because it is easier to construct from accrual‑based financial statements.

The indirect method reconciles net income to the cash flow from operating activities by:

1. Adding back non‑cash expenses like depreciation.
2. Adjusting for gains or losses on asset sales.
3. Adding or subtracting changes in current assets and liabilities (excluding cash and short‑term debt), because these represent timing differences between profit recognition and actual cash movement.

The sum of the three buckets — operating, investing, and financing — explains the total change in the firm’s cash balance from the beginning to the end of the period. If the statement of cash flows tells you anything, it’s this: a company can be profitable on paper and still burn through cash, which is why the statement of cash flows is the final reality check.

📝 Section Recap: The statement of cash flows classifies all cash movements into operating, investing, and financing activities. It bridges the gap between accrual accounting and the firm’s actual cash position, making it a key tool for understanding liquidity and financial flexibility.

Summary#

We began with three simple but powerful financial statements and discovered that they are not just dry compliance documents — they are the tools that reveal whether a firm is really creating cash value. The balance sheet gave us a snapshot of what the firm owns and who funded it. The income statement told us how much profit the operations generated, while reminding us that profit is not cash. By digging into net working capital and the cash flow identity, we learned to calculate free cash flow — the lifeblood that keeps a business alive and rewards its investors. Finally, the statement of cash flows knitted everything together, showing exactly how the cash balance changed over a period. With these concepts in hand, you can now look beyond accounting profits and see the real financial story of any company.
