Companies create reserves in anticipation of probable future costs or losses whose amounts can be reasonably estimated, as happens with inventory reserves and loan-loss provisions, or, in order to ensure comparability across accounting methods as happens with LIFO reserves.

While operational excellence should be the lodestar guiding managers, there is a great temptation to use reserves to manage earnings. In order to ward off the effects of earnings management, ensure comparability across business, and reveal timing of recurring cash flows from operations, the change in LIFO reserves, other inventory reserves and loan loss reserves year-over-year are added to my calculation of net operating profit after tax (NOPAT).

“Change in Reserves”, Joseph Noko

The worries expressed in my short note on the change in reserves, pertain to the balance sheet as well, with managers well capable of adulterating asset values through the innocent exercise of the discretion that the rules allow. Reserves are added back to assets as part of my invested capital calculation.

Taxes incorporate operating, non-operating and financing items. One wants to assess the core operations of a business, free of any financing effects, in order to estimate net operating profits after tax (NOPAT), and so, one must break off operating taxes, from taxes on non-operating accounts, and other non-operating taxes. This gives us the taxes the firm would pay if it only engaged in its core activities and was wholly equity financed.

I start with reported provision for income taxes or income tax expense, and then subtract the change in the deferred tax account in order to convert taxes from an accrual to cash basis. When a company pays less in cash taxes than it reports in book taxes, it earns a deferred tax liability, a source of cash, and when it pays more in cash taxes than it reports in book taxes, it earns a deferred tax asset, a use of cash. The deferred tax account can be found on the balance sheet, but when they are not separately detailed, the relevant information can be found in the cash flow statement under the “Cash flows from the operating activities” section, as part of the adjustments to reconcile net income to net cash provided by operating activities; or, it can be found in the footnotes.

Then, I unlever cash taxes by adding back the debt tax shield from from net interest expense and operating, variable and not-yet commenced leases. This is done by multiplying the debt expense by the marginal tax rate, and adding the sum to cash taxes. Finally, I reverse the impact other non-operating accounts. Where there is information on tax benefit of non-operating items, with pre and post-tax values given, I reverse the impact of that as well. This process gives us an estimate of cash operating taxes.

This whole process can be seen in the example below in which I calculate Diamond Hill’s cash operating taxes.

These are the result of currency revaluations or devaluations and do not appear on the face of the income statement. These currency fluctuations force firms to assume non-recurring charges or gains. An example is the $12 million Tesla gained in 2013 when the Yen’s plunge reduced Tesla’s Yen-denominated liabilities. David Trainer, the CEO and founder of New Constructs, notes that,

The Bolivar Fuerte was adopted as the national currency of Venezuela in 2008. Companies operating in Venezuela must obtain government approval to exchange Bolivars to US Dollars at the official exchange rate. Effective January 1, 2011, the Venezuelan government established a fixed rate of 4.30 per dollar. Again, effective February 13, 2013 the currency was further devalued to a rate of 6.30 per dollar. This change caused many companies to take large charges on the remeasurement of their Venezuelan operations for their 2013 fiscal years. Such a charge is a one-time, non-operating expense and is not indicative of the operations of the company.

“NOPAT Adjustment: Foreign Exchange Loss“, David Trainer

These non-recurring charges are added back to net income in order to arrive at a truer reflection of NOPAT.

Reported net non-operating charges and gains are those non-operating items reported on the face of the income statement. According to the paper, “Core Earnings: New Data and Evidence” by Ethan Rouen, Eric So, and Charles C.Y. Wang, they are “similar in magnitude… to those reported off the face of the income statement”. Examples of such items are interest expense/income, minority interest income, preferred dividends, asset impairments, and losses on debt extinguishment, as this except from the Commercial Metals Company’s 2023 10-K shows: 

These items are added back to net income in order to arrive at a measure of net operating profit after tax (NOPAT).

The Financial Accounting Standards Board (FASB) eliminated goodwill amortisation from 2002 and the International Accounting Standards Board (IASB) followed in 2005. Before that, goodwill, the capitalised value of the excess of purchase price over fair value of identifiable assets, required an annual charge to earnings for up to 40 years until the value of goodwill was eliminated. (Warren Buffett’s essay, “Goodwill and its Amortisation: The Rules and The Realities” in the appendix to his 1983 chairman’s letter, is an excellent discussion of goodwill amortisation). Since those accounting changes, goodwill is now subjected to impairment testing, which, unlike goodwill amortisation, is a real economic cost to the firm. Following “Core Earnings: New Data and Evidence” by Ethan Rouen, Eric So, and Charles C.Y. Wang, for years before the rule change, I add the goodwill amortisation charge to net income and for years after the rule change, the goodwill impairment charge, so as to arrive at a better measure of net operating profit after tax (NOPAT). 

Effective 2005, the IASB required employee stock options (ESO) to be expensed in the income statement, with the FASB following a year later. Until then, firms could treat ESO compensation as if it was not a cost, inflating their reported earnings. Consequently, for the era before this accounting change, one must dig up data from the footnotes in order to calculate the cost of ESO issuances and ensure that results are comparable across periods and add the charge to net income so as to arrive at a better measure of NOPAT.

Under both IFRS and US GAAP, assets and liabilities held for sale are reported separately on the balance sheet and their income and loss from them, or the result of their sale, are reported as discontinued operations separate from continuing operations. This forms part of the business’ net income, adulterating the firm’s earnings. 

In my pursuit of core profitability, I strip away the impact of income and losses from discontinued operations. For example, in its 2023 10-K, the Commercial Metals Company reported a $2.3 million gain on the sale of assets, and net earnings of $859.76 million. In order to properly estimate the recurring, and repeatable profitability of the business, it is necessary to remove this $2.3 million gain. 

Because real estate investment trusts (REITs), by their nature, dispose of property, I do not perform the same exercise for REITs, choosing instead to incorporate such income and losses into my calculation of NOPAT.
