Overhead… Who Cares?

IMG_6295-002

You probably couldn’t stop your accountants from allocating overhead to your operating profit centers, even if you tried. I’m not a business historian, but somewhere along the line, accountants everywhere became convinced that allocating overhead to operating unit P&Ls results in a better understanding of profitability. That may or may not be true, but let’s not use an accounting concept for making business decisions.

What is Overhead?

Overhead has a different meaning in every company, and its calculation varies widely. Generally speaking, though, it is considered to be the cost of running a head office, including centralized costs such as executive salaries, office rent, computer systems, etc. When the accountants allocate overhead, it is often in the form of a percentage of gross revenue. If a company has a division that contributes 10% profit, and another that contributes 8%, a 4% overhead allocation would reduce these results to 6% and 4%.

In this example, it would appear that the first division is 50% more profitable than the second, and management might be tempted to allocate resources accordingly. But its contribution margin is only 25% higher, so the result could be misleading.

If you can’t tell if your operations generate enough profit to cover overhead, you might consider looking for a different occupation. For the record, I’m sure many intelligent people disagree with me.

Don’t include Overhead in your business decisions

In my experience, many accountants don’t really appreciate that accounting conventions have no place in business decision-making, and operating executives often don’t feel confident enough to challenge the accountants on their own turf. Some things to remember:

Overhead is just an accounting concept
Overhead does not affect cash flow
Overhead allocations do not affect total company profitability
Overhead is calculated differently in every company

I have seen some dysfunctional results arise from trying to shoe-horn an accounting concept into business decisions.

A Retailer

A retailer had several stores that were not only losing money, but had a negative cash flow. That is, their operating loss was greater than their depreciation and amortization. The stores clearly needed to be closed to stop the damage.

The CEO, however, had done his math. If he closed the failing stores, the overhead allocated to those stores would have to be redistributed to the remaining stores, reducing their accounting profit after overhead. The CEO could not be persuaded that closing the losing stores would improve the company’s total profitability.

The failing stores continued to lose cash flow, and the overhead was allocated to all stores… until the CEO was replaced.

A Homebuilder

A homebuilder had a target IRR for new community construction projects. IRR is a measure of cash flow that calculates the return realized on a cash investment. The CFO, an accountant by training, insisted that all cash flow projections include a 3% charge for overhead, despite the fact that overhead has nothing to do with the incremental cash flow generated by a new construction project. He argued that when the project was under way, overhead would be allocated for accounting purposes, so the pro formas should reflect that. The pro formas then became just a forecast of the accounting records, and IRR, the real reason for making the investment, was calculated incorrectly.

At least the pro formas were conservative as a result of this allocation, but the company probably missed out on some good opportunities whose IRR projections fell below the hurdle rate. As it happened, the company’s actual overhead was not even 3% at all.

Another Retailer

Some retailers charge the cost of their distribution centers directly to expense, in the manner of unallocated overhead, while others include it in the cost of their merchandise, charging it directly to operations.

In a year when earnings were tight, I was encouraged as division CFO to find ways to increase reported profit, so I capitalized the distribution center costs. This resulted in a large transfer of costs from expense to inventory, substantially increasing reported earnings. The parent company paid senior management large bonuses that year, regardless of the fact that nearly all our profit came from an accounting change.

Although we reported more profit, the actual economic impact on the company was a negative cash flow in the amount of the bonuses that were paid. Was the accounting technically correct? Yes. Was it the most appropriate accounting under the circumstances? Maybe not. Would I do it again? … Well, I did like that bonus.

A Land Developer

When a land developer sold finished and partially finished lots to homebuilders, they did a land residual calculation to arrive at the asking price. That is, they estimated all the builder’s costs and revenues, and priced the lots so the builder could achieve a specified percentage profit margin. But one of the costs included in the analysis was 3% – again 3% – for overhead. If they didn’t include the overhead, they could have started with a higher asking price, and maybe sold the lots for a higher price.

Does your CFO take a practical view of Overhead?

ROI versus IRR … In a Nutshell

IMG_7243-002

Both the CEO and the CFO of a large company told me that ROI and IRR are the same thing.  They’re not. Interestingly, both executives’ annual bonus was determined by how their ROI compared with other companies in the industry.

I worked for a big company that required a 16% after-tax IRR on new investments. As it happened, the company’s ROI was typically in the 16% range. The Director of Financial Planning told the operating teams that achieving a 16% IRR automatically resulted in a 16% ROI… But he was wrong. It was just a coincidence.

Another company required an 18% pre-tax IRR on new investments, and for several years reported an ROI of about 18%. That was also a coincidence.

ROI and IRR are very different calculations, and are used for very different purposes.

Return on Investment (ROI)

ROI is a measure of how effectively a company is utilizing its capital investment.  It measures the company’s profit during a fixed period of time, usually one year, divided by its average assets.

Calculating ROI

Pretax Profit Before Interest  /  Average Total Assets, excluding Capitalized Interest  (-)  Average Non- Interest Bearing Liabilities

Taxes and interest are excluded from the calculation in order to compare the performance of different companies more effectively. A company with a low tax rate, or a highly leveraged company will have very different result from those of a company that has higher taxes or operates with low debt levels, so this calculation removes those variables. Other calculations, such as Return on Equity (ROE) evaluate performance on a more comprehensive basis.

Non-interest bearing liabilities include items like accounts payable and accrued liabilities, which are effectively free financing, so the corresponding assets aren’t really considered to be an investment.

How Useful is ROI?

ROI is a widely used calculation, but we must remember that it measures only one year’s performance, so it can swing widely from year to year if earnings are volatile. This may not be a bad thing in cyclical businesses, in which all companies experience the same environment.

In my opinion, ROI is most useful in established companies that are not growing or contracting at a rapid rate. The book value of a young company or a growing company’s assets is likely to be relatively high, as they invest in future earnings, and haven’t charged off extensive depreciation and amortization.

Conversely, there is an old joke that the best way to increase your ROI is to go out of business, because your investment is declining as you sell off assets, while you still report income from the sale of those assets.

Similar Calculations

There are plenty of slightly different calculations such as Return on Net Assets (RONA), Return on Capital (ROC) and Return on Invested Capital (ROIC) that can be argued to be more representative of a particular company’s performance, but they all have the same basic objective.

Internal Rate of Return (IRR)

IRR calculates the compound rate of interest earned over the life of a specific investment, using not only the dollar amounts, but also the timing of cash expenditures and cash receipts.  Because it uses the concept of the “time value of money,” IRR is used to compare investment opportunities that have very different cash flows.

Calculating IRR

IRR is based on the concept of Net Present Value (NPV). NPV says that one dollar today is worth exactly one dollar. A promise to receive one dollar a year from now, however, is worth less than a dollar, because you’ve missed the opportunity to earn income on that dollar for a year. If you could earn 10% (the Discount Rate) on your investment, next year’s dollar would be worth only 90.9 cents today ($1.00 divided by 110%).  On the bright side, a future expense is also worth less today.

IRR is the Discount Rate at which the NPV of a series of cash flows is zero. That is, the interest rate earned over the life of an investment after the initial investment has been repaid.

Typically, interest and taxes are also excluded from the IRR calculation for comparison purposes, but of course, you will want to see the net leveraged IRR too.

How Useful is IRR?

If you have $1 million cash to invest, should you invest in the project that requires the entire investment up front, then pays nothing for 3 years, when it returns $1.5 million? Or should you go for the one that requires a $500,000 investment in each of the first two years, and then pays $350,000 a year for the next 5 years? There are obviously a lot of other factors to consider, but IRR will tell you which one pays a higher return.

Similarities Between ROI and IRR

None… ROI and IRR are entirely different calculations.
