Accruals and Working Capital

The four kinds of accrual that separate profit from cash, how to measure the cash a company's daily operations tie up, and why the estimates inside accruals deserve attention.

The short version

An accrual is the gap between when something is recorded and when the cash moves. There are four kinds: sales not yet collected, costs not yet paid, cash paid before the cost is recorded, and cash collected before the sale is recorded. Together they make up working capital, the cash tied up in running the business day to day. Days of receivables, inventory, and payables turn those balances into something comparable across years and companies, and the cash conversion cycle adds them into one number. A growing company usually needs more working capital, which uses cash. Many accruals are estimates, so they're also where profit can be nudged up or down.

By the end of this lesson, you'll be able to

  • Name the four kinds of accrual and where each sits on the balance sheet
  • Calculate days of receivables, inventory, and payables, and the cash conversion cycle
  • Explain how accrual estimates can shift profit between years

Why this matters

Why Earnings and Cash Differ showed that timing is one of the main reasons profit and cash come apart. This lesson goes into that timing. It matters for two reasons. The balances involved decide how much cash a business needs just to operate, and they're built partly on estimates, which makes them the easiest place to adjust a profit figure.

Four kinds of accrual

Financial statements use : transactions are recorded in the period they happen, even if the cash is received or paid in a different one.1 Whenever the record and the cash fall in different periods, a balance appears on the balance sheet to hold the difference. There are four cases.

The four timing gaps
What happenedBalance sheet lineEffect
Sale recorded, cash not yet collected (asset)Profit ahead of cash
Cash paid, cost not yet recorded, prepaid expenses (assets)Profit ahead of cash
Cost recorded, cash not yet paid, accrued expenses (liabilities)Cash ahead of profit
Cash collected, sale not yet recorded (liability)Cash ahead of profit

The first two use cash: the company has earned or bought something it hasn't been paid for or hasn't sold. The last two provide cash: suppliers, employees, and customers are, in effect, lending to the company for a while.

Working capital

Add the first two and subtract the last two, and the result is operating : the net cash tied up in day-to-day operations. For STU Corp, the fictional company from Part 3:

STU Corp's operating working capital, $ millions
This yearLast yearChange
Accounts receivable5044+6
Inventory4540+5
Accounts payable(30)(27)(3)
Accrued expenses(10)(9)(1)
Deferred revenue(15)(12)(3)
Operating working capital4036+4

Working capital rose by $4 million, so operations absorbed $4 million of cash. That's exactly what the cash flow statement shows: the five working capital lines in STU Corp's operating section add up to a $4 million outflow. The cash flow statement reports the changes. The balance sheet shows the levels.

Working capital is 10% of STU Corp's $400 million of revenue. As a rough guide, that means each extra $100 of sales ties up about $10 of cash before any profit arrives. Fast growth can leave a profitable company short of cash for this reason alone.
