This
treatment takes changes in net deferred tax liabilities (or assets) and
adds them back to income (or subtracts them from taxes---same effect)
and adds the net deferred tax liability to net assets (or the reverse
treatment for deferred tax assets). If there is a valuation allowance
reducing the deferred tax assets, that allowance would also be added to
capital and any increase (decrease) in that allowance added (subtracted)
to income. The effect of this adjustment is to reflect taxes in EP on a
cash basis. Only taxes actually paid would affect EBIT while taxes that
are deferred, i.e., the cash not paid to the government and still in the
business, remain in Capital. For example:
Income before
interest* and taxes $800
Tax provision*
$300
+ Change in deferred tax liability $100
Cash taxes
$200
EP
$600
* Interest is assumed to have been added back to income after-tax;
or, if interest has been added back pre-tax, then the tax provision is
presumed to have been adjusted by the add-back of the tax benefit of
interest.
If a company grows its deferred tax
liabilities, EBIT would be higher than it would be absent this
adjustment, but so would be Capital---and the requirement to earn
returns on that additional Capital. However, as deferred taxes
"unwind," i.e., come due because the asset is aging or has
been sold, EBIT will be lower than it would have been absent the
adjustment while Capital appears to decline.
The rationale for cash taxes is that
management will pay much closer attention to taxes if the cash impact
of tax payment is reflected in the period-to-period accounting of
Income. While that is certainly true, there are some distinct
drawbacks to this treatment. The first is that management may be
making value added expenditures that are being appropriately
capitalized for a while, then decide that the investment opportunity
has temporarily dried up. The moment management holds back on further
such expenditures, the tax benefits disappear and EP will
automatically drop. Thus, managers would be penalized for making the
value-driven decision of withholding spending on poor investments. The
second drawback is that management may have grown a line of business
for a while until it reaches a mature stage where further growth
becomes difficult. By then, the deferred tax liabilities of that
business have also grown to a substantial amount and the shareholders
have benefited from the deferral of tax payments. However, a new
management is faced with the value-added disposition of the line of
business and, if they sell it, the tax deferrals unwind. Despite
significant value creation from the sale, EP would inevitably take a
large hit.
Thus, while cash operating taxes provides
the highest degree of sensitivity to tax consequences of business
activities, it can only provide reasonable matching of revenues,
expenses, and capital charges in a business environment unlikely to
see any slowdown in its growth or sale of assets.
Finally, if we truly revert to cash
taxes, this would imply undoing the prior treatment (Option 1) as it
pertains to capitalized charges and expenses. Recall from the examples
in Option 1 that if we capitalize an expense that has a current period
tax benefit, then treating that tax benefit on a cash basis will make
almost any such expense "EP positive" in the year it is
incurred. We would be automatically rewarding spending, per se. While
management may be penalized in later years for such expenses, the day
of reckoning can be delayed for many years as long as the expense
keeps growing. Thus, even when choosing cash operating taxes, it is
advisable to capitalize (and, if appropriate, amortize) the tax
benefit of capitalized charges.
