The Impact of Taxes and Ownership on the Performance and Capital
Structure of S Corporation Banks
A popular criticism of U.S. federal income tax policy is that owners of corporations are
taxed twice, first at the corporate level under the corporate income tax and again at the
shareholder level as individuals pay personal income tax on any dividends and capital gains.
Such criticism, however, applies only to C Corporations. S Corporations avoid this double
taxation, with certain limitations, because the underlying entity does not pay corporate federal
income taxes. Instead, individual shareholders pay tax at personal tax rates on any income
allocated to them. To the extent that S Corporations are able to avoid double taxation they
provide a natural experiment to examine the impact of taxes on the firms choice of capital
structure. Furthermore, because S Corporations are closely held due to restrictions on the number
of shareholders, their owner-managers may exhibit different perspectives on risk and profitability
objectives.
Researchers, such as Modigliani and Miller (1958 and 1963), Scott (1976), and Miller
(1977), have long debated the influence of taxes on the capital structure decisions of
corporations. Many argue that corporations find it optimal to hold at least some debt because
interest payments are tax deductible for the corporation, while dividend payments on equity are
not similarly treated. In a survey of firm managers, Graham and Harvey (2001) verify that firm
managerstrade-off the benefits versus distress and tax costs of debt via target debt ratios.

Adherents of this trade-off theory implicitly argue that S Corporations, which pay no federal
income tax and thus have no advantages from debt, would hold proportionately less interest-
bearing debt and more capital.
Whether a firm operates as an S or C Corporation also likely affects operating
performance and managements risk tolerance. Clearly, the avoidance of corporate income taxes
should improve a firms bottom line. Equally important, however, is the prospect that
concentrated ownership may reduce agency problems and subsequently improve risk
management practices. When Congress initiated legislation allowing certain corporations to elect
S Corporation structure, it imposed limits on the maximum number of shareholders allowed. The
current maximum is 100 shareholders with broad definitions that, in some instances, allow
family members to constitute one shareholder. The possibility of improved risk management
practices is linked to the types of firms that select S Corporation status and the tendency of
owner-managers to lead the firms.
With constraints on the number of shareholders, S Corporations are generally smaller in
terms of asset size and market value than their C Corporation counterparts. Limiting the number
of shareholders concentrates ownership, especially among the Board of Directors and
management. According to Berle and Means (1932), Jensen and Meckling (1976) and
subsequent researchers, concentrated ownership mitigates negative consequences of the
separation of ownership from control of the corporation. As such, S Corporations could have
smaller agency problems and stronger operating profits, ceteris paribus.
While S Corporations outnumber C Corporations in recent years, little research has
examined the structure and performance of S Corporations likely due to data limitations. Because
S Corporations are generally small in size and non-public, comprehensive financial data are not

as readily available as for publicly-traded corporations. However, detailed balance sheet and
income statement data are available for S Corporation commercial banks. The Small Business
Job Protection Act of 1996 authorized qualifying insured commercial banks to be taxed as S
Corporations (S Corp. banks) effective in 1997.1 Not surprisingly, the ability to avoid federal
corporate income taxes (and in some cases, state taxes) has been quite attractive and the number
of banks that selected S Corporation status has increased sharply. Figure 1 highlights changes in
the number of S Corp. banks from 1999 to 2009 when almost one-third of U.S. commercial
banks operated as S Corporations.
This research empirically examines the operating performance and capital structure of S
Corporation commercial banks relative to that of C Corporation commercial banks. In doing so, we
examine a tradeoff hypothesis associated with managementschoice of financial leverage and an
agency hypothesis associated with firm operating performance. First, because interest expense on
debt is not tax deductible for S Corp. banks, the tradeoff hypothesisimplies that S Corp. banks
operate with less interest-bearing debt relative to comparable C Corp. banks. Second, because
ownership and managerial control of S Corp. banks are highly concentrated relative to that for C
Corp. banks, the agency hypothesisstipulates that S Corp. banks exhibit greater operating profits
after controlling for risk. This latter hypothesis reflects, in part, reduced agency problems
associated with managers and owners who are closely aligned when making managerial decisions.
In conducting the empirical analysis, we address potentially serious endogeneity problems.
For example, while we could easily compare key performance ratios between banks representing
the two groups, differences might be driven by the types of banks that choose to be taxed as S
1 Prior to 1997, commercial banks and savings associations were prohibited from electing to be organized as S
Corporations regardless of the number of stockholders.

Corporations versus C Corporations. Given the limitations on the maximum number of
shareholders, S Corporations are likely to be smaller, more frequently located in rural settings, and
more likely to be regulated by state banking departments rather than the OCC or Federal Reserve
System. Differences in performance or capital structure may simply reflect these structural
differences.
We focus our attention on banks in large part because of data availability. S corporations,
by their very nature, are small entities and thus generally dont have publicly-traded securities.
However, all U.S. commercial banks are heavily regulated and are required to publicly provide
basic financial information on a quarterly basis. Regulation, in turn, encompasses allowable
balance sheet mix, minimum capital standards, and other elements that make commercial banks
unique. We discuss some of these unique features in our development of hypotheses. Finally, our
research does not allow us to explore market prices for securities which are not available for
virtually all S Corp. banks. As such, we are forced to consider non-traditional measures of risk and
return (i.e. those not directly related to modern portfolio theory) in our analysis. The remainder of
the paper describes the nature of the empirical analysis and presents estimates of differences in
performance and capital structure.
1. RELATED BANKING LITERATUREGiven that S Corporation banks have only been in existence in the U.S. following 1996
Congressional legislation, little empirical research exists regarding their performance. Hodder,
McAnally and Weaver (2003, HMW) were among the first to examine S Corp. banks and
identified tax and nontax factors likely to influence the choice to incorporate as an S
Corporation. They find that banks are more likely to convert to S Corporation status when the

conversion lowers dividend taxes and minimizes state income taxes. They also find that banks
are less likely to convert when conversion would lead to capital constraints or create penalty
taxes on unrealized gains.
Hein, Koch and MacDonald (2005, HKM) build on the importance of relationship
banking to smaller, community banks in the U.S. They note that a growing proportion of smaller
banks organize as S Corporation banks each subsequent year. These smaller banks, in turn, are
shown to be more profitable than larger banks. HKM (2005) emphasize that part of this increased
profitability is simply attributable to the fact that S Corporations pay no federal income tax such
that after-tax comparisons between S Corporation banks and C Corporation banks are not
appropriate. Gilbert and Wheelock (2007, GW) go one step further and show that S Corporation
banks have higher earnings than their peer C Corporation banks even after the formersearnings
are reduced by estimated federal income taxes. The better profitability is largely attributed to
higher net interest margins and greater operating efficiency. GW does warn, however, that there
is no perfect way to compare S Corporation and C Corporation bank earnings to one another.
Thus, there is some evidence suggesting that S Corporation banks are more profitable
than their C Corporation counterparts, even after controlling for tax differences. There are two
limitations to this evidence, however, that this paper attempts to rectify. First, no theory has
been offered to explain why these differences exist. We argue that because S Corporation banks
are likely to be smaller and more closely-held, they will engage in more relationship banking
activities, which have been shown to be more profitable, and they are likely to be better able to
mitigate the agency costs of equity. Second, the earlier evidence has not controlled for problems
with self-selection bias. For example, it might be the case that more profitable banks have an
-

incentive to convert to S Corporations and the evidence of greater profitability may be
attributable to this fact rather than S Corporation status.
The hypothesis linking S Corporation status to increased bank profitability is related to
literature on smaller organizations ability tobetter exploit soft information and to literature on
mitigating the agency costs of equity. Brickley, Linck and Smith (2003), for example, provide
evidence showing that locally-owned bank offices in Texas grant more decision-making
authority to local managers, allowing for better exploitation of soft information. They find that
small locally-owned banks have a comparative advantage over larger banks. While they do not
examine the corporate status of the banks in their study, S Corporation banks are more likely to
be locally-owned. Berger, Miller, Petersen, Rajan, and Stein (2005) also find evidence
consistent with the observation that small banks are better equipped to collect and act on soft
information than are large banks.
Mehran and Suher (2009) also give explicit consideration to S Corporation banks. They
focus primarily on dividend payouts and bank acquisitions and find evidence that S Corporation
banks dividend payouts increase following conversions from C Corporations. They also find
evidence that S Corporation banks are significantly less likely to be sold relative to C
Corporation banks. Finally, they find that S Corporation banks operate less efficiently on a
pretax basis in contrast with the results of GW (2007).

2. A PRELIMINARY COMPARISON OF C CORPORATION AND S CORPORATIONBANK PERFORMANCE
To conduct our preliminary analysis, we use year-end balance sheet and income
statement data from Federal Financial Institutions Examination Council (FFIEC) bank reports of
income and condition (Call Reports) for 1999-2008.2We initially report key bank performance
and balance sheet ratios for S Corp. banks in the year of conversion versus the same measures for
C Corp. banks. Generally, S Corporations cannot own other S Corporations.3
We conduct our analysis at the bank level as opposed to the holding company level.4
Figure 1 shows recent trends in the number and proportion of S Corporation banks. As indicated,
the proportion of S Corporation banks increased dramatically over time from 16 percent in 1999
to 30 percent in 2008 and higher thereafter. Summing the number of banks across all years gives
a final sample of 15,637 S-Corporation and 44,360 C-Corporation bank-years.
S Corporation banks differ from their C Corporation counterparts in many ways.
Consider the summary univariate data in Table 1 which document size, location, and capital
differences for all banks separated according to S or C Corp. status. For comparative purposes, C
Corp. banks are those operating in each year with total assets no greater than that of the largest S
Corp. bank that year. At year-end 2008, 48percent of S-Corp. banks had less than $100 million
in assets and only 160 had more than $500 million in assets. The largest S Corp. bank in our
sample at the end of 2008 had $3.5 billion in assets. Not surprisingly, almost 70 percent of S
2
While banks were first allowed to choose S Corporation status in 1997, we omit data for 1997 and 1998 because
the FFEIC reports do not explicitly identify which banks are S Corp. banks.
3An S Corporation that owns 100 percent of the stock of another corporation, however, can elect to treat the
subsidiary as a qualified subchapter S subsidiary.
4We have also conducted the analysis at the holding company level with similar results. These results are availableupon request.

Corp. banks were headquartered in rural areas. The number of S Corp. banks increases
systematically over time as does the relative size of the average bank. Generally, the reported
data for capital ratios, equity-to-total assets and the adjusted capital ratio (stockholders equity
divided by the difference between total assets and non-interest bearing deposits) are
systematically lower for S Corp. banks, but sufficiently close to the ratios for C Corp. banks to
necessitate further investigation.
We compare key performance measures for S Corporation banks to the same measures
for C Corporation banks matched by total asset size. Variables are separated into three
categories: 1) profitability, 2) balance sheet mix and risk, and 3) capital measures. The measures
are widely used in the banking literature, but some might be new to those not familiar with
banks. Table 2 presents means of key ratios for S Corporation banks versus means for a size-
constrained, matched sample of C Corporation banks. Specifically, the matched sample for each
year includes all C Corporation banks that reported total assets no greater than the amount of
total assets for the largest S Corporation bank in that year. The table provides t-statistics, testing
for differences in the means between S Corporation and C Corporation banks. Because these
results are simple partial comparisons and we have not controlled for potential endogeneity
problems, we view these findings as primarily descriptive. Still, the results described here are
broadly consistent with the more sophisticated two-stage estimation provided in Section 5.
2.1 Profitability
Our findings regarding bank profitability comparisons are broadly consistent with those
of GW (2007) as S Corporation banks have, on average, much higher after-tax aggregate profits
measured by both ROE and ROA. They also report net interest margins (NIMs) that are 17 basis
-

11/38
11
points higher, on average, while our estimate is 24 basis points. In order to neutralize the tax
advantage of S Corp. status, we also construct pre-tax profit ratios. Importantly, S Corp. banks
report significantly higher average ratios for pre-tax ROE and pre-tax ROA. This finding is
similar to that of GW (2007), but the opposite finding of MS (2009). The difference in the pre-
tax and after-tax ROA for S Corporation banks is small and largely reflects differential state
taxes. This preliminary evidence supports the view that S Corp. banks earn higher returns, even
ignoring their tax advantages, with the differences in pre-tax ROE and ROA between the two
groups at 1.84 percent and 0.16 percent, respectively. After subtracting taxes, average ROE and
ROA are approximately 60 percent greater at S Corporation banks. This latter comparison clearly
demonstrates the error in treating these two corporate structures equally when evaluating
performance based on traditional benchmarks like ROE and ROA. Not surprisingly, S Corp.
banks pay a higher fraction of income as dividends as most S Corp. shareholders are subject to
income taxes on their share of bank profits. This finding is consistent with the evidence provided
in MS (2009). Finally, profit growth is significantly higher for S Corporation banks over the
prior three years.
2.2 Balance Sheet Mix and Risk
Data for the balance sheet mix variables reveal that S Corp. banks fund their operations
differently. First, they operate with proportionately more demand deposits but fewer other core
deposits, such as small time deposits, MMDAs, and savings accounts. Second, they have fewer
purchased liabilities, such as repurchase agreements and FHLB advances, compared with their C
Corp. bank peers. Demand deposits are unique to commercial banks as they represent non-
interest bearing liabilities. Historically, individuals viewed their primary bank relationship to be
-
8/13/2019 Impact of Taxes and Ownership OnCapital Structure S Corp Banks May2010 to JFI
12/38
12
with the firm that provides these checking account services. Demand deposits held by individuals
are highly interest inelastic and represent a stable, low cost source of funds. Thus, most banks
view demand deposits as a core driver of firm value. Banks pay market rates on purchased
liabilities which are generally higher than rates paid on core deposits. The overall funding
characteristics suggest that S Corp. banks have a lower average cost of funds and less liquidity
risk. The fact that other core deposits is lower at S Corp. banks may mitigate this claim, but may
also reflect the widespread acquisition of time deposits and MMDAs via internet CDs and rate
boards during this time frame by C Corp. banks. Finally, as noted below, S Corp. banks have
lower equity-to-asset ratios and thus greater financial leverage. This raises interest expense,
ceteris paribus.
On the asset side, S Corp. banks hold proportionally fewer total loans, but more
agriculture and commercial loans. With the different loan mix and loan levels, S Corp. banks
report higher past-due loan ratios, but there is no difference in net charge-offs suggesting that
their credit risk management experience has been comparable to that of C Corp. banks, on
average. Interestingly, S Corp. banks have lower asset growth than their C Corp. counterparts.
Given that we havent controlled for whether S Corp. banks compete in more restricted
geographic markets, the differential asset growth may simply reflect that more C Corp. banks
operate in faster-growing metropolitan areas. Additionally, S Corp. banks are more likely to be
de novo banks and thus might purposely limit asset growth, something we control for in the
following analysis. It may also reflect the fact that S Corp. banks pay more in cash dividends.
Finally, S Corp. banks hold more liquid assets possibly reflecting a greater need to pledge
securities against public deposits and greater reliance on unpledged securities for liquidity given
their more limited access to purchased liabilities.

2.3 Capital
Finally, the various capital ratios indicate that S Corp. banks operate with less
stockholders equity to assets, both before and after adjusting for non-interest bearing demand
deposits, and lower Tier 1 risk-based capital ratios.5A banks equity-to-asset ratio is a traditional
measure of financial leverage. The adjusted capital ratio subtracts demand deposits from total
assets in the denominator in recognition that most banks will accept all the demand deposits that
they can attract. They can effectively spread the deposit servicing cost over a larger base and
easily invest the funds earning a positive spread. The adjusted capital ratio attempts to control for
financial leverage not associated with interest expense.
Given likely constraints on the amount of common stock that a limited number of
individual shareholders can often acquire, even if tax considerations dont matter, S Corp. banks
likely obtain proportionately more capital in the form of trust preferred stock that is sold to
external constituents. The data, however, indicate that S Corp. banks operate with relatively less
preferred stock and subordinated debt financing.
5The Tier 1 risk-based capital ratio is a measure of capital adequacy that was developed with the Basel I capital
standards. The ratio is simply Tier 1 capital to risk weighted assets. Tier 1 capital is the regulatory definition of
capital that is most closely aligned with common stock holders equity. The risk-weighted assets of a bank are found
by classifying all assets into one of four categories, each with weights between 0% and 100%. The measure of risk-
weighted assets also includes certain off balance sheet items to capture non-balance sheet financial risks. S Corp.
banks similarly have greater demand deposit financing which is quite stable. They may choose to operate with
relatively less equity given the lower risk sources of debt utilized.

3. EMPIRICAL DESIGNThe previous findings are consistent with those of GW (2007) indicating that S
Corporations are generally more profitable, even allowing for their tax advantage, than their C
Corporation counterparts. Our univariate findings are also generally contrary to the tradeoff
theory, as S Corporation banks have less equity than their counterparts, on average. Finally, the
findings are consistent with the agency view that S Corporations have higher risk-adjusted
returns. However, this investigation suffers from potential endogeneity problems, as we have not
controlled for factors that might shape the decision to elect S Corporation status. The univariate
analysis may simply indicate that banks which elect to become S Corporations may themselves
be more profitable and hold less capital. We attempt to mitigate the endogenous variables
problem by using the Heckman (1979) correction procedure which requires the empirical
analysis of factors that are likely to lead a commercial bank to elect the S Corporation structure.
Fortunately, HMW (2003) suggest factors that appear to influence this choice. We begin by
outlining their analysis, which is used to develop the first step in our Heckman estimation. The
empirical results follow.
3.1 Factors Influencing the S Corporation Election
HMW focus on tax matters that shape a banks decision to elect the S Corporation
structure. The comparison of tax benefits between S and C Corporations, in turn, requires an
analysis of expected taxable income and dividend payouts and the relationship between marginal
corporate and personal income tax rates. HMW represent the tax benefit of conversion to an S
corporation as the sum of two terms; the savings from avoiding individual taxation of dividends
and an offset reflecting incremental taxes due because marginal corporate income tax rates are
-
8/13/2019 Impact of Taxes and Ownership OnCapital Structure S Corp Banks May2010 to JFI
15/38
15
less than marginal personal income tax rates (at least for the maximum income tax rate
schedules):
Tax benefit = [dividends x ti] + [taxable income ( tc - ti) ] , (1)
where dividends and taxable income represent cash dividend payments and earnings subject to
taxes as a C Corporation, respectively, and tcand tirefer to the banks marginal corporate and
shareholder marginal personal income tax rates, respectively. Equation (1) indicates that higher
dividends should produce a greater tax benefit from S Corporation conversion, ceteris paribus,
and that an increase in taxable income, holding dividends constant, may result in a lower net
benefit because income may be taxed at the higher individual shareholder tax rate. The special
circumstances of individual stockholders and the amount of taxable income determine the
magnitude of the overall tax benefit. For example, consider a bank owned by one stockholder
who is a dairy farmer with an effective personal tax rate of zero (ti= 0). Operating as a C Corp.
bank generates a dead weight cost by reducing the amount of income available for payment as
dividends. In contrast, S Corp. taxation avoids this cost and increases the after-tax value of cash
dividend payments to the stockholder. Similarly, a C Corporation with substantial built-in gains
will be required to pay taxes on the unrealized built-in gains over time at the maximum corporate
tax rate if it converts to an S Corporation. Thus, conversion to an S Corp. bank would sharply
increase taxable income. Not converting defers any recognition of the gain which may induce
management to not seek S Corporation status until the built-in gains are minimal.
The role of dividends is likely to be even more important than that suggested by this
framework. Suppose a commercial bank makes a positive profit, retains all earnings, and pays no
dividends. As a C Corporation, it would pay corporate taxes on all earnings but the double
taxation is minimal as shareholders pay no income taxes because they receive no dividends. In
-
8/13/2019 Impact of Taxes and Ownership OnCapital Structure S Corp Banks May2010 to JFI
16/38
16
this scenario, shareholders can effectively postpone individual tax obligations indefinitely. A tax
event at the individual level occurs only when the shareholder sells stock with the tax impact
determined by whether the sale is at a gain or loss and whether the marginal personal income tax
rate is greater (lower) than the capital gains tax rate. As an S Corporation, the bank would pay no
corporate income tax, but taxable income would be allocated to shareholders regardless of
whether cash dividends were paid, so shareholders would pay income tax at a (presumably)
higher tax rate with tc- ti< 0.
HMW generally argue that banks are more likely to convert from a C to an S Corporation
when conversion reduces stockholder dividend taxes and state income taxes and helps
stockholders avoid the alternative minimum tax.6They also argue that smaller banks are more
likely to make the S Corporation election. On the other hand, banks in growth markets with
limited access to the capital markets and those with significant corporate tax loss carry-forwards
are less likely to convert.
HMW estimate a logistic regression model where the choice of S Corporation status is
related to a banks cash dividend payments, taxable and tax-exempt income, growth rate in total
assets and purchased liabilities during the three prior years, unrealized gains on investment
securities, the existence of tax loss carry-forwards, age of the bank since incorporation, and the
natural log of total assets. They also include a series of dummy variables to capture favorable tax
and regulatory factors, labeled tax variables, non-tax variables and control variables. Tax

When a C Corp. elects to operate as an S Corp., it must treat any unused AMT credit as a carry-forward item and
can use it to offset built-in-gains taxes over the 10-year recognition period. Many banks buy municipal bonds that
pay interest exempt from federal income taxes and this interest increases the banks alternative minimum taxable
income under the AMT. The key issue is how to determine how many municipals to own and the amount of the
AMT credit.

benefits are determined by the amount of dividends paid along with aggregate bank taxable
income. Importantly, dividends will have a positive impact on the election of S Corporation
status as long as the respective marginal corporate tax rate is less than the relevant marginal
individual income tax rate. In general, any factor that creates less benefit of conversion to S
Corp. status, such as having large built-in-gains that would offset the tax benefit, should decrease
the likelihood of conversion.
In order to assess performance differences, we need to control for selection bias. Our first
stage analysis is based largely on the framework proposed by HMW that models managements
decision to elect the S Corporation organization form. We estimate a probit regression of the
form:
S Corporation = f (BUILTIN, LOSSCF, AMT, DIVPAY, Yearly Dummies,
STATEDUM, RURAL, AGE, LNASSETS) (2)
with S Corporationequal to one if the bank chooses to be an S Corporation for the first time in
that year, and zero otherwise;BUILTINequals unrealized capital gains on investment securities
scaled by total assets if positive, and zero if a capital loss exists;LOSSCFis a zero-one indicator
that takes a value of one if the prior three years losses are greater than the current years profit;
AMTis HMWs proxy for the alternative minimum tax, defined as tax-exempt interest divided
by assets;DIVPAYis the banks total cash dividends for the year divided by operating profits;
Yearly Dummies, YR00-YR08, are indicator variables that equal one if in the year suffix, and
zero otherwise with 1999 the excluded set; STATEDUMis an indicator for the state in which the
bank is located and zero otherwise, omitting Washington, DC7;RURALis one if the bank is not
7While for sake of space we do not report the coefficients on the state dummy variables, we should note these
coefficients are generally highly significant. This reflects the fact that the treatment of S Corp. banks varies greatly

18
in an MSA, and zero otherwise;AGEis the number of years from charter date; andLNASSETSis
the log of total assets.
The Heckman (1979) correction uses the inverse Mills ratio from the first stage probit
regression that estimates the probability of selecting S Corporation status. The correction helps
account for possible selection bias because banks that elect to become S corporations may also
have better profit performance, differential capital ratios, and balance sheet mix. We are
particularly concerned whether banks that choose to be S corporations generate higher profits or
may operate with differential financial leverage independent of the choice.
3.2 Comparative Bank Tax Treatment, Operating Performance and Capital Structure
The different tax treatment of S Corp. versus C Corp. banks potentially leads to
different balance sheet structures and operating performance which may be compounded by
differences in ownership structure of the two types of banks. We are first interested in bank
performance and agency effects on risk management practices. We hypothesize that the close
alignment of ownership and control of many S Corp. banks mitigates potential agency conflicts
between owners and managers. One implication is that S Corp. banks may, on average, better
manage banking risks and subsequently produce higher risk-adjusted profits. For example,
managers of S Corporations are likely less willing to engage in perquisite consumption due to
their (generally) larger pro-rata share of ownership than most C Corporation managers. They are
also likely to be better incentivized to find profitable, risk-adjusted investment opportunities.
This discussion leads to the agency hypothesis:
from state to state which is reflected in the fact that some states have very few S Corp. banks while other states have
large numbers of S Corp. banks.

Agency Hypothesis: S Corp. banks exhibit greater profits than comparable C Corp. banks.
This should be obvious in the case of after-tax returns, as S Corp. banks avoid the federal income
tax burden of their C Corp. brethren. However, we also argue that S Corp. banks will be more
profitable than their C Corp. peers on a before-tax basis.
Next, we consider two competing theories and their capital structure implications. First,
we consider the tradeoff hypothesis, which emphasizes the lack of tax deductibility of debt for
S Corp. banks. In particular, the avoidance of federal corporate income taxes eliminates the tax
advantages of interest-bearing debt for S Corp. banks, suggesting a tradeoff hypothesis:
Tradeoff Hypothesis: S Corp. banks operate with less interest-bearing debt and more
equity capital than C Corp. banks.
To the extent that S Corp. banks do not directly derive tax benefits from the interest expense on
debt, they may hold relatively less of this debt relative to their C Corp. counterparts. Importantly,
S Corp. banks may rely proportionately more on trust preferred stock. Banks with a limited
number of shareholders and strong growth prospects historically found such stock attractive due
to its low cost and ready availability without diluting the ownership of existing shareholders.
Trust preferred stock and subordinated debt qualify, with limitations, as Tier 1 capital which
helps meet regulatory capital requirements. Trust preferred stock has the distinct advantage over
common equity because dividend payments are effectively tax deductible. Thus, the use of
preferred stock and subordinated debt lowers a banks cost of capital and we include bothin our
capital structure equations.8
In contrast to the tradeoff hypothesis, we build on the agency benefits of the S Corp.
structure and develop an alternative hypothesis. Traditional theories of capital structure start with
a presumed target level for the capital stock that is achieved by flow changes over time. The
8The use of trust preferred stock by community banks largely disappeared with the credit crisis that began in 2007.

4. EMPIRICAL EVIDENCETable 3 contains the probit results for S Corp. selection by banks. The first two columns
present the probit regression estimates and p-values for the raw data, while the last two columns
contain standardized coefficient estimates (each variable is standardized by dividing the value by
the full sample standard deviation for that variable) and the rank of each variables impactbased
on the standardized data. The standardized data estimates indicate which variables have the

greatest influence on the probability of becoming an S corporation for banks in this sample. The
last column contains the ranking (1 indicates the highest and 17 the least impact) based on the
absolute value of the effect.9
Our first stage findings are similar to those of HMW except for investment capital gains
as a fraction of assets (BUILTIN) where the coefficient estimate is not statistically different from
zero andLOSSCFwhere we find that a higher loss of tax benefits is associated with a higher
probability of S Corporation election. Regarding the LOSSCF variable, we follow HMW and
have an indicating variable that take on a value of one if the prior three years losses are bigger
than this years profit.These differences may be due to our longer sample period or the different
empirical specification. However, we confirm HMWs finding forAMT, where higher
proportions of tax-exempt securities owned are associated with lower probabilities of S
Corporation election. Similarly, the coefficient on the dividend payout rate variable has the
anticipated positive sign and is significantly different from zero indicating that banks electing to
become S Corporations generally have higher dividend payout rates. Dividends better enable S
Corp. shareholders to satisfy their personal income tax obligations which have been passed on to
them at the personal income level. The dividend payout variable is the most significant variable
in shaping the decision to adopt S Corporation status as indicated by the highest rank for the
standardized estimates (aside from the yearly dummy variables and intercept). Surprisingly,
rural banks are not more likely to elect S Corp. status, on average.
Table 4 presents the results from the second stage regressions which represent our tests of
the trade-off and its alternative, as well as the agency hypotheses.First, consider the results for
9 Note that for consistency with the raw data results, we do not report the standardized state indicator estimates even

CAPRATIO and the capital structure implications. While the control variables exhibit the
anticipated signs, S Corp banks appear to operate with less equity-to-assets, ceteris paribus, and
thus greater financial leverage in contrast to the predictions of the tradeoff hypothesis.
Importantly, the more banks rely on preferred stock the lower are overall capital ratios such that
this other form of regulatory capital appears to contribute to lower traditional equity ratios.
While the evidence is broadly inconsistent with the tradeoff hypothesis as outlined above with S
Corporations having less equity than C Corporations, it is supportive of the alternative view that
managers of S Corp. banks feel that they dont need as large of a capital stock to begin with since
they are better equipped to add to it by retaining earnings from their higher profits.
The significant LAMBDA coefficient estimate suggests that the sample bias correction is
necessary in all three models. The interpretation is that the higher the probability of choosing S
corporation status, the lower is pre-tax and after-tax ROA, but the higher is the capital ratio.
These effects offset the higher performance and lower capital of actual S Corp. election as shown
by the indicator variable, hence the differences in the model accounting for selection bias and the
one that does not.
Consider next the agency hypothesis. The results for pre-tax ROA demonstrate that S
Corp. banks have higher pre-tax ROAs than their C Corp. counterparts, ceteris paribus,
suggesting that S Corp. banks perform better even after accounting for possible selection bias.
The estimates indicate a 42 basis point increase in pre-tax ROA, a 76 basis point increase in
after-tax ROA, and an approximate 86 basis point decline in the capital ratio.10The estimates are
10The derivative of the inverse Mills ratio is not linear so that including the LAMBDA variable as an independent
regressor in a second stage OLS model does not give a true derivative. These results are thus not true partial
derivatives for S Corporation status.

similar to the model without the Heckman correction (not shown), which indicates a statistically
significant 17 basis points pre-tax ROA, 49 basis points after-tax ROA, and 38 basis points lower
capital ratio. Regardless of the model used, these estimates are economically meaningful and
indicate higher performance and lower capital ratios for S Corp. banks that are not due to sample
bias. The implication is that S Corp. banks appear to manage risk comparably with C Corp.
banks while generating greater profitability. As such, we cannot reject the agency hypothesis
which suggests that S Corp. banks operate with higher risk-adjusted profits than C Corp. banks.
Other control variables provide additional insight into S Corp. bank performance and
risk. Rural banks have higher ROAs while de novo banks have lower ROAs as expected, and
correspondingly operate with less and higher capital, respectively. De novo banks must have
sufficient start-up capital to offset poor early performance. S Corp. banks that have grown assets
quickly have lower performance and capital ratios suggesting a tradeoff between asset growth
and accounting performance. Larger banks have higher profitability and lower capital ratios, all
else equal.11 Banks with higher loan losses have lower profitability and capital ratios while
banks with higher proportions of total loans and commercial lending have higher performance
and lower capital. Finally, the structure of funding greatly influences performance. Banks with
the greatest proportion of funding from demand deposits are more profitable and operate with
less equity, while those that rely proportionately more on other core deposits and purchased
liabilities are less profitable yet also operate with less equity.
4.1 A Comparison of Bank Performance after versus Before S Corp. Selection
In this section, we incorporate another method for analyzing performance differences
after controlling for conversion to S Corp. status. Specifically, we examine differences in means
11Note that the largest banks in the sample have total assets no greater than the largest S Corp. bank.

25
in key variables for S Corp. banks in the 3-year period prior to conversion versus the first three
years after conversion. The final two columns of Table 5 provide t-statistics and z-statistics,
respectively, for differences in means and medians when comparing post-conversion minus pre-
conversion performance variables. The results demonstrate that capital ratios did not change
significantly, except for the Tier 1 risk-weighted ratio, which fell, on average after conversion.
Again, the lower Tier I capital ratio finding is consistent with our alternative hypothesis to the
trade-off theory. Post-conversion, S Corp. banks also relied proportionately less on preferred
stock as a capital component.
In terms of profitability, after-tax ROA and ROE increased sharply, as expected, but both
pre-tax ROA and ROE declined, on average. This latter finding is not expected, but may reflect
the different timing of when banks converted to S Corp. status relative to the economic cycle or
alternatively a general decline in profitability at S Corp. banks over time. Or, it may reflect the
view that S Corp. banks follow expense preference behavior after conversion when there are
fewer owners and managers consuming greater perquisites. As expected, S Corp. banks pay
much higher dividends after conversion.
In terms of balance sheet mix, S Corp. banks increased loan-to-asset and loan-to-deposit
ratios, but also experienced greater past due loans and net charge-offs after conversion. These
results may similarly reflect timing differences between when banks converted across the
business cycle. Finally, S Corp. banks appear to have reduced their reliance on other core
deposits but increased their reliance on purchased liabilities after conversion. This change in mix
of liabilities would have contributed to lower profits, ceteris paribus.
In order to control for changes in the business cycle, we conduct the same tests pre- and
post-conversion after subtracting the yearly mean or median for all banks from each variable.

26
These results are presented in Table 6 and serve to confirm the previous analysis. Using adjusted
means, capital ratios generally fell post-conversion except for S Corp. banks use of preferred
stock. In terms of profitability, both pre-tax ROA and ROE increased after conversion, as did
post-tax ROA and ROE, net interest margin, profit growth and the dividend payout ratio when
accounting for industry performance. In other words, the results in Table 5 where pre-tax
performance fell after S Corp. conversion were due to yearly effects and performance did
increase for S Corp. banks after conversion when accounting for these annual industry effects.
Combined with the earlier results, the implication is that S Corp. banks reduce their capital, but
increase their aggregate profitability, both pretax and post-tax, following conversion.
5. SUMMARY AND CONCLUSIONS
S Corporations provide an interesting corporate structure to examine the influence of
taxes on financial decision making. Because these organizations generally avoid income taxes at
the corporate level, leverage and tradeoff theories appear to suggest that S Corporations would
employ more equity and less debt in their capital structures given that debt is not tax-advantaged
at the corporate level. Our examination of the behavior of S Corporation banks, however,
provides no evidence consistent with this hypothesis. Indeed, S Corporation banks are found to
operate with less equity, ceteris paribus, than their C Corporation counterparts. We view these
results as consistent with our alternative hypothesis to the trade-off theory that emphasizes the
strong profitability of S Corp. banks. Specifically, managers of these banks recognize their
greater ability to add to their capital by retaining earnings in the future, so they have a lower
capital stock target. Our results suggest that tax associated with interest expense on debt play a
