OPTIONS VALUATION
MODELS
I read with interest How to Excel at
Options Valuation (JofA, Dec.
05, page 57). It appears that the strength of the
binomial model presented is inversely related to
the number of assumptions made. In the example
given in the article, for four years of stock
options granted, there are 16
assumptionsperhaps not very persuasive. For
n years, there would be an exponential
number of assumptions, or 2^n.
In general, one can create various simulations
of stock option valuations, all based on
statistically valid models. For example, a
simulation based on a model whereby mean and
standard deviation represent the basis for
underlying assumptions can provide similar
results to the binomial results but on a normal
distribution scale. The latter has the added
benefit of allowing the model to report a level
of confidence for the simulated results.
The crux of the matter is in research that can
show such a simulation is not only statistically
valid but also realistic. For example, showing
the value of stock options before and after an
IPO vs. the simulated costing of such options may
prove or disprove the validity of the valuation.
A successful model that has bearing on reality
can be put in the same class as the Black-Scholes
method and be an acceptable alternative.

MODIFIED STATEMENTS
FOR NPEs
I fully agree with the sentiments expressed in
the letter Different
Standards for Nonpublic Companies? (JofA,
Jan.06, page 11). I have been financing nonpublic
businesses for banks and finance companies and
rely on financial statements to make credit
decisions.
In particular I agree that the idea of
different standards for different sizes or types
of companies is extremely dangerous. Where will
it end? What all users want is an accurate
financial statement, and the same principles
apply to all of them.
If the cost of compliance with a particular
disclosure rule is out of proportion to the
benefit, then the accountant preparing a
statement for a credit grantor should leave it
out and qualify his opinion accordingly,
preferably with the prior approval of the user.
My experience is that very few nonpublic
companies have the items, such as stock options
or pension funds, that give rise to additional
disclosures and costs. It would be up to the
credit grantor to accept or not accept a modified
statement. I believe this approach would be
preferable to tinkering with GAAP.

ANOTHER SOCIAL
SECURITY FIX
In addition to the proposals offered in the
letter A
Social Security Solution (JofA,
Jan.06, page 12) and the article Promises to Keep
(JofA, Jul 05, page 41), I have one that
brings the income tax system and Social Security
together in a unique way.
One of the arguments offered for the creation
of private accounts is that when a retiree dies
the money can be passed on to his or her heirs.
But most recipients of Social Security depend on
their payments almost exclusively for their
income. One of the last things on their minds is
to pass money on to heirs. They need every dollar
to pay basic needs such as housing and medicines.
If private accounts were in place, guaranteed
regular payments would have to be reduced.
The exception to this majority would be
high-income individuals whose Social Security
payments are extra income. The
payments would simply be added to their savings.
A possible solution would be to offer high
income individuals, at some time during their
working career, the choice to receive a tax
deduction for the amount of their yearly payments
into Social Security. The deduction could be in
the form of a schedule A deduction from their
personal income tax return or an adjustment to
total gross income before computing adjusted
gross income. In exchange they would forfeit the
right to receive Social Security payments when
they become eligible. The total amount paid into
the Social Security reserve fund would not
changethe employer would match the employee
deduction as usual. The employee would benefit
annually with tax savings as well as with the
compound interest savings and investment effect
of the savings.
The IRS would have to compute the loss in
income tax revenues from such a proposal and
compare it to the savings in the Social Security
reserve fund as a result of not having to pay
future benefits. I believe there could be a net
savings to the overall federal budget.
The implementation of such a system could be
complex, but it would not require as radical a
change in the Social Security payment system as
some other proposals would.
