Net Operating Assets

Net operating assets, or NOA, are a business’s operating assets minus its operating liabilities. The figure comes from sorting every line on the balance sheet into an operating item or a financing item, then netting the two operating totals, so what is left is the investment tied up in running the business, with the funding question held separately. Nothing reports it. No caption on a filed balance sheet carries it and no ledger account holds it, which makes it a reformulation an analyst performs rather than a figure the accounting produces.

The Formula, Term by Term

net operating assets   =  operating assets - operating liabilities

operating assets       =  total assets - financial assets
operating liabilities  =  total liabilities and preferred stock - financial obligations

The first line is not usable until the other two are settled. A reformulation assigns every balance sheet item to a category and maintains the balance sheet totals, so that total assets equal operating assets plus financial assets, and total liabilities and preferred stock equal operating liabilities plus financial obligations (Nissim and Penman, Ratio Analysis and Equity Valuation, March 1999). Rearranged, those two identities are how each operating total gets computed. Whatever is not financial is operating.

Which side a line falls on turns on why the item exists. Operating liabilities are those generated by operations, such as accounts payable, wages payable, pension liabilities and deferred tax liabilities, while financial liabilities are those from raising funds to finance operations, and financial assets such as bonds held are available to finance operations and effectively reduce the debt raised for them (Nissim and Penman, Ratio Analysis and Equity Valuation, March 1999).

The reformulation draws the same operating and financing division on the income statement, and the operating income it pairs with net operating assets is measured after tax (Nissim and Penman, Ratio Analysis and Equity Valuation, March 1999). That is not the pre-tax subtotal, operating income before interest and income tax, that the equation for operating income works through.

A second convention starts from the other end and computes each operating total as a residual. Net operating assets are the difference on the balance sheet between all operating assets and all operating liabilities, with operating assets taken as total assets less cash and short-term investments, and operating liabilities taken as total assets less short-term debt, long-term debt, minority interest (the stake in a consolidated subsidiary the parent does not own), preferred stock and common equity (Hirshleifer, Hou, Teoh and Zhang, Do Investors Overvalue Firms With Bloated Balance Sheets?, March 2004). Both routes describe the same subtraction. Neither one is a rule, and they do not have to land on the same number for the same balance sheet.

Why No Balance Sheet Carries It

Regulation S-X indicates the line items which, if applicable, should appear on the face of the balance sheets or related notes filed with the Commission, closing the asset side at total assets and the statement at total liabilities and equity (17 CFR 210.5-02). Those captions divide assets from liabilities and equity, and current from non-current, the presentation set out in classified balance sheet, and the walk down the liability captions themselves is in asset to liabilities ratio. Not one of them separates operating from financing, and not one of them is net operating assets.

No account holds it either, so it does not appear on a trial balance, and no combination of ledger balances produces it until someone has classified each account as operating or financing. Someone has to build it outside the accounting system, from statements the accounting system produced. A figure labeled net operating assets therefore means what its preparer’s classification made it mean, and nothing more.

Why One Balance Sheet Supports Two Answers

Because the number is built rather than posted, the work is the classification, and the classification is not always determinate. Some items are inherently difficult to classify as either operating or financing, and a residual method can inadvertently omit operating items or include financing ones (Hirshleifer, Hou, Teoh and Zhang, Do Investors Overvalue Firms With Bloated Balance Sheets?, March 2004).

The clearest case is cash. Operating cash is often lumped together with short-term investments, so a residual measure that strips the whole caption drops the operating part of it too. Long-term marketable securities cut the other way, since they can be sold in the short term if a cash need arises and can therefore behave like a financing item rather than an operating one (Hirshleifer, Hou, Teoh and Zhang, Do Investors Overvalue Firms With Bloated Balance Sheets?, March 2004).

Two people working from different conventions hand you two defensible answers from the same balance sheet, so a figure under this name is only usable beside a statement of how it was built. The same holds across periods, and there it is quieter, because a change in the split moves no reported line and leaves no entry behind to mark it.

A Worked Example

Say a client’s balance sheet closes on the amounts below.

Total assets                                          1,850,000
Cash and short-term investments                         240,000
Short-term debt                                         150,000
Long-term debt                                          400,000
Total liabilities and preferred stock                   930,000

operating assets           1,850,000 - 240,000        1,610,000
financial obligations        150,000 + 400,000          550,000
operating liabilities        930,000 - 550,000          380,000
net operating assets       1,610,000 - 380,000        1,230,000

net financial obligations    550,000 - 240,000          310,000
common equity              1,230,000 - 310,000          920,000
check: 1,850,000 - 930,000                              920,000

Net financial obligations is the financing side netted the same way, the financial obligations less the financial assets (Nissim and Penman, Ratio Analysis and Equity Valuation, March 1999). Nothing was added or taken away. The same lines were sorted into two piles and each pile was netted, which is why the last two rows agree. That agreement is worth checking, but it only proves every line was assigned once and none was assigned twice. It says nothing about whether a line landed on the right side, and that judgment is where the figure is made or lost.

Net Operating Assets Against Net Assets

Net assets are total assets minus total liabilities, the whole residual in one subtraction. Net operating assets are one side of a different subtraction: common shareholders’ equity equals net operating assets less net financial obligations, and less any minority interests a consolidated balance sheet carries (Nissim and Penman, Ratio Analysis and Equity Valuation, March 1999).

Net assets nets everything and stops. Net operating assets nets only the operating half, and the financing half stands beside it as its own figure, so the two coincide only where the financing side nets to nothing. Both are book figures, which is what separates them from enterprise value, the market-priced view of the same operating side.
