Environmental liabilities and stock price responses to FASB Interpretation No. 47.
Hunsader, Kenneth J. ; Dickens, Ross N.
INTRODUCTION
The Financial Accounting Standards Board (FASB) announced Financial
Interpretation Number 47, Accounting for Conditional Asset Retirement
Obligations, on March 30, 2005. The interpretation (FIN47) seeks more
consistent recognition of liabilities relating to asset retirement
obligations (AROs) and a standardization of information concerning
carrying amounts of assets based on additional estimable retirement
costs. Although FIN47 could affect all companies with future conditional
obligations, it requires firms with environmental liabilities to alter
the companies' reporting of such issues. We use this opportunity to
judge the impact on stock prices for companies with likely environmental
concerns.
Prior to 2005, companies with environmentally contaminated properties could sidestep accounting for potential liabilities through
"mothballing" the property. Mothballing occurs by letting the
property sit idle and not offering it for sale and/or avoiding
investigating possible remediation needs. This strategy would delay any
cleanup costs and also keep investors unaware of the scope of potential
liabilities. FIN47 requires reporting such potential liabilities and,
thus, leads companies toward greater transparency.
Managers might opt for less transparency to hide negative
information and, thus, increase their ability to beat earnings
benchmarks and/or deliver smoother earnings (Degeorge & Zeckhauser,
2000) while improved transparency should allow a reduction in asymmetric
information, increased liquidity, and a lower cost of capital (Botosan,
1997). Thus, FIN47 could lead to negative stock price reactions if
managers have been hiding negative information which now must be
reported or the announcement could have a positive impact on share
prices if added transparency provides the benefits Botosan (1997) notes.
Given transparency failures (such as Enron and WorldCom), regulators
have acted to increase corporate disclosure--with the 2002
Sarbanes-Oxley Act's being the most far-reaching example, but FIN47
is also a part.
The purpose of FIN47 is to create a fair market for all
participants by providing stakeholders--such as community members,
taxpayers, various government entities, and investors--with as much ARO
information as possible. Community members may be most concerned about
possible health implications of "toxic" sites. Taxpayers and
governments worry that companies may discharge their liabilities via
bankruptcy filings; leaving the public to bear the costs and risks of
reclamation (Habegger, 2005). (Note that in a 2003 Accountability Office
(GAO) report, the Environmental Protection Agency (EPA) is partially or
wholly funding 60 of the largest 142 Superfund (toxic) sites with each
site having an estimated cost of $140 million or more. A specific
example of firms not bearing full cleanup costs is Asarco which filed
bankruptcy in 2005 with $500 million to $1 billion in environmental
liabilities for which its parent company, Grupo Mexico, set up an
environmental trust fund with only $100 million to help pay cleanup
costs.) Investors would want the ARO information accurately reflected in
the companies' market prices.
The purpose of this study is to examine the stock market response
to FASB's FIN47 announcement for companies in industries which are
the most likely to have potential environmental liability possibilities:
mining and manufacturing (especially the subset of chemical firms). In
general, we find significant negative wealth effects for manufacturing
firms. Variations in abnormal returns appear related to company-specific
factors evaluated under the Environmental Protection Agency's (EPA)
measures of financial distress. We also find that companies identified
as top corporate polluters have significant shifts in systematic risk
after the announcement.
The remainder of the paper is as follows: we provide historical
background of environmental liability reporting, review related
literature review, discusses our data set and methodology, and then
presents the results. Finally, we provide a summary and concluding
remarks.
HISTORICAL BACKGROUND
Prior to 2001, FASB Statement No. 5 "Accounting for
Contingencies" (Statement 5), FASB Interpretation No. 14 (FIN14),
and Statement of Position (SOP) 96-1 issued by the American Institute of
Certified Public Accountants (AICPA) guided companies' handling of
possible environmental liabilities. Statement 5 set forth a
"two-prong" approach in which a company should recognize a
liability when: 1) it is probable that the company has incurred a
liability and 2) the company can reasonably estimate the amount. In
response, companies addressed the first prong by following a defining
approach as if the event were "more likely than not to occur".
FIN14 is FASB's effort to provide an estimation approach for the
second prong. Under FIN14, loss contingencies could be stated at their
"most likely value". If a firm could not determine this value,
the company could provide a range for a loss contingency and use the
lowest amount. Finally, SOP 96-1 provided added guidance relating to
environmental cleanup obligations. Rogers (2008) states that since these
three items "tended to favor certainty over projections, they have
been criticized for delaying recognition of contingent liabilities,
understating recognized liabilities, and failing to provide users of
financial statements with useful, transparent, and timely
information".
As an attempt to address the above issues and provide uniformity in
evaluation processes, the FASB developed FAS 143, "Accounting for
Asset Retirement Obligations (AROs)" in 2001. FAS 143 requires that
the liabilities for existing legal obligations be recognized when
incurred-which is typically when the asset is acquired or developed
through construction. This recognition assumes the company can assess
the liability's fair value where the best definition for "fair
value" is the "transfer" price between market
participants although fair value may be set by using the best
information available at the time. Soon, the FASB became concerned about
accounting practice differences for recognizing conditional asset
retirement obligations (CAROs)--AROs which are conditioned on a future
event such as selling a currently operating production facility. In some
cases, companies claimed they could not estimate the fair value given
uncertainty while others claimed no legal liability since the obligation
could be indefinitely deferred (mothballed).
The FASB issued FIN47 on March 30, 2005 to clarify how companies
should apply FAS 143 regarding CAROs. The new interpretation states that
a firm should recognize the CARO when incurred which includes
acquisition, construction, or development of the asset. Also, the firm
should incorporate any uncertainty regarding the timing or structure of
the settlement of an obligation into the calculation of the
liability's value. With regards to environmental liabilities, a
company must report future environmental cleanup obligations on its
balance sheet even if there are no plans to end production or sell the
asset. If an ARO is not reasonably estimable through an active market
for transferring the asset, applying a present value technique, or
through an acquisition price to determine the value, FIN47 requires a
company to disclose that the liability has not been recognized along
with an explanation supporting the reasons why.
LITERATURE REVIEW
The passage of the Sarbanes-Oxley Act (SOX) of 2002 brought
attention to the impact that environmental liabilities may have on firms
given that CEO's of public companies must certify that the
financial statements fairly represent the firm's financial
position. Schnapf (2006) states that some firms hired environmental
consultants to get actual cleanup cost data. The passage of FIN47 will
likely accelerate this trend.
Regulation requiring increased disclosure and its effect on firm
value has drawn attention in recent years. Recent examples in the
literature concern the Sarbanes-Oxley Act (SOX) of 2002. Zhang (2007)
finds that U.S. firms experience a negative wealth effect around key SOX
event dates. Wintoki (2007) reports that negative wealth effects are
more pervasive for firms with higher growth opportunities and greater
operating environment uncertainty. Thus, the passage of increased
reporting requirements seems a greater cost to growth firms (which tend
to be younger, smaller in size, and have more fluid operating
environments) relative to low-growth firms (which are usually older and
operate in a more stable environment).
In a separate study not directly related to SOX, Cox & Douthett
(2009) find that confirmatory environmental disclosures reduce negative
wealth effects relative to non-confirmatory disclosures. A confirmatory
disclosure is one which indicates a firm's joint strategy to act
environmentally responsibly while pursuing higher financial performance.
A non-confirmatory disclosure does not indicate a simultaneous pursuit
of both goals. Thus, the authors conclude that investors'
perception of a combined strategy affects market valuation.
Lee & Hutchison (2005) provide a survey of research regarding
company characteristics related to the decision to disclose
environmental information. Firm size is a significant factor. Hackston
& Milne (1996), Cormier & Magnan (2003), Patten (1991), Adams,
Hill, & Roberts (1998) all find a significant positive relationship
between firm size and environmental reporting. However, Cowen &
Parker (1987) provide conflicting evidence as they report a negative
relationship in the U.S. based on size.
Industry affiliation is influential as well. Trotman & Bradley
(1981), Cowen & Parker (1987), and Patten (1991) note that the more
sensitive an industry is to the environment; the greater the level of
disclosures. Thus, firms in an industry segment such as chemicals, would
have more disclosures relative to a general manufacturing firm.
Firm systematic risk is an added explanatory variable. Trotman
& Bradley (1981) find that the higher a firm's systematic risk
(as measured by beta), the greater the likelihood of social
transparency. Similarly, Cormier & Magnan (2003) find risk
positively associated with transparency while leverage is inversely
related with environmental disclosures in annual reports. The
relationship between profitability and environmental disclosure is
uncertain. Buhr (2002) finds that profitability is an important variable
in reporting environmental issues for pulp and paper industry firms. In
addition, Cox & Douthett (2009) find the level of environmental GAAP disclosure is related to firm profitability in terms of return on
assets. However, Patten (1991) and Hackston & Milne (1996) find no
relationship with regard to profitability.
A final potential area related to financial disclosure in regards
to environmental liabilities is financial tests. Habegger (2005) reports
that any firm applying for a permit for an environmentally hazardous project must demonstrate financial assurance to the issuing state's
agency. This assurance that the company has the ability to fund all
costs associated with environmental liabilities is to protect taxpayers
as well as the environment. To obtain a state permit, firms must pass
one of two alternative EPA financial tests or obtain external assurance
such as insurance or letters of credit.
The EPA's first test requires a firm to meet four conditions.
1) The firm's finances must meet at least two of three ratio tests:
a) total liabilities to net worth less than 2.0, b) the sum of net
income plus depreciation, depletion, and amortization to total
liabilities greater than 0.10, and/or c) current assets to current
liabilities greater than 1.5. 2) The firm must have tangible net worth of at least S10 million. 3) Tangible net worth and net working capital
must each be at least six times the current closure cost estimate for
all the company's facilities. 4) Assets located in the U.S. must
amount to at least 90 percent of the firm's total assets or at
least six times the current closure cost estimate for the total of all
facilities.
The EPA's second test requires the company to meet the second,
third, and fourth requirements as the first test, but with a current
bond rating of BBB (Baa) or greater by Standard and Poor's
(Moody's). These firm-specific financial conditions may affect the
stock market response to the passage of FIN47. (The mining industry is
subjected to somewhat different financial assurance standards given
alternative regulatory agencies. For example, coal mining reclamation is
assured by the Department of Interior's Office of Surface Mining
Reclamation. Coal mining companies must have a current ratio of greater
than 1.2 times and ratio of liabilities to net worth of 2.5 times or
less. Oil companies with offshore facilities guaranteeing the ability to
clean spills are assured through the Department of Interior's
Mineral Management Service. Corporate guarantees of financial assurance
are not accepted for onshore oil and gas reclamation. We use EPA
guidelines for all data screening processes.) On the one hand, firms
with values that currently fail EPA standards could be considered to be
in even worse positions if forced to report added CAROs. However, firms
which currently pass EPA tests could arguably be in for a more negative
reaction. If reporting CAROs would make a firm which currently meets
requirements to no longer pass, then that newly failing firm would
either lose the EPA's imprimatur or have to utilize some other
assurance mechanism such as insurance. Such impacts would be, at best,
costly and likely lead to negative stock price reactions.
DATA AND METHODOLOGY
The sample focuses on the mining and manufacturing industries given
their likely environmental challenges and includes 1,716 firms with
stock price data available from the Center of Research in Security
Prices (CRSP) and accounting data for the year 2004 on Research Insight
(Compustat). Of the firms included, 121 are in the mining industry
(two-digit SIC codes from 10 to 14), and 1,595 firms are from the
manufacturing industry (two-digit SIC codes from 20 to 39). Table 1
reports the summary statistics of the sample. (Appendix I provides a
breakdown of the number of companies by industry.)
The median total debt-to-equity ratio (DE) is 0.65 while the mean
is 1.37 which both meet the EPA's guideline of less than 2.0. (We
emphasize median values as that informs us as to the 50th percentile
company's ability to meet EPA standards.) The median value for net
income plus depreciation divided by total liabilities (NIDEP/TL) is 0.16
which is above the EPA's minimum guideline of 0.10. The median
current ratio (CR) is 2.57--well above the minimum EPA level of 1.5. The
median market value (MV) is S345 million which is well over the S10
million floor set by the EPA. Thus, the median value comparisons show
that more than 50% of all sample companies for each variable meet the
EPA requirements.
As our measure of tangible net worth (TNW), we use total assets
minus total liabilities minus intangibles from Research Insight.
(Research Insight's intangibles variable includes 21 items such as
copyrights, goodwill, and patents.) The median value is $69.74 million.
The median value of net working capital (NWC) is $65.79 million. The
third EPA condition requires these two values to be six or more times
the current closure cost estimate. As in Habegger (2005), we estimate
total current closure cost to be 1% of the net plant, property and
equipment (PPE) account. The median value of PPE is $37.47 million, thus
1% of that amount is $0.37 million. Dividing the median values for TNW
or PPE by the median closure cost estimates yields values of 175 times
or more (which are well over the six times requirements of the EPA).
As most firms do not have actively traded bonds, we employ
Altman's bankruptcy prediction test (Z-score) as a proxy for
default risk ratings. We take Z-score values from Research Insight and
find a median score of 3.72. However, 328 firms fall below a score of
1.81 which indicates a high probability of bankruptcy. Overall, based on
median values, the average firm in the sample would seem to have little
trouble meeting the minimum guidelines of the EPA's tests for
financial assurance, but some firms would not meet requirements in all
areas.
Table 1 also reports the summary statistics for the manufacturing
(Panel B) and mining (Panel C) industries separately. No test for
statistically different mean values between the two subsamples is
significant (mostly due to the relatively large values for standard
deviations).
Given the common event period (the date of FIN47's enactment),
we employ a multivariate regression model (MVRM) as suggested by Binder (1985a and 1985b) and Schipper & Thompson (1983) to correct for
possible heteroskedasticity biases. (Under standard event study
methodology, a common event period means individual asset returns will
be contemporaneously correlated such that residuals across the various
firm type portfolios would not be identically and independently
distributed.) Following Bhargava & Fraser (1998), we employ a system
of Seemingly Unrelated Regressions (SUR) and include a time lag variable
to control for non-synchronous trading. The event date, [t.sub.0], is
the announcement date of the passage of FIN47 (March 30, 2005), and the
model specification is:
[r.sub.it] = [[alpha].sub.i] + [[alpha]'.sub.i][D.sub.t] +
[[beta].sub.li][r.sub.m(t-1)] + [[gamma].sub.i][D.sub.o] +
[[beta]'.sub.i][D.sub.t][r.sub.mt] +
[[beta]'.sub.li][D.sub.t][r.sub.m(t-1)] + [[epsilon].sub.it]
where [r.sub.it] = the return for portfolio i on day t,
[[alpha].sub.i] = intercept coefficient for portfolio i,
[D.sub.t] = dummy which is 1.0 after the last event date; else 0.0
(= 1.0 for day +2 to day +120),
[[alpha]'.sub.i] = shift intercept coefficient for portfolio
i,
[[beta].sub.i] = systematic risk coefficient on market return for
portfolio i,
[r.sub.mt] = the return on the equally weighted market portfolio on
day t,
[[beta].sub.li] = systematic risk coefficient on the lagged market
return for portfolio i,
[[gamma].sub.i] = the wealth effect of the announcement on
portfolio i for the event,
[D.sub.o] = dummy which is 1.0 in the event window; else 0.0 (= 1.0
for day -1 to day +1),
[[beta]'.sub.i] = shift in systematic risk for portfolio i,
[[beta]'.sub.li] = shift in systematic risk for portfolio i on
the lagged return, and
[[epsilon].sub.it] = error term.
To compute abnormal returns, we estimate the model parameters using
120 trading days before and after the event date in the fashion of
Saunders & Smirlock (1987). We calculate cumulative abnormal returns
(CARs) by adding the abnormal returns for a given portfolio, across the
event window (days -1 through day +1). Next, we separate the portfolios
based on whether a firm meets a given EPA standard and examine CARs for
firms which pass the criterion as opposed to those which fail. For each
of these seven model estimation groupings, we utilize the full sample as
well as subsets based on whether companies are in the mining,
manufacturing (including chemical), or just chemical industries.
We predict a negative sign for debt to equity (DE) since firms with
higher DE values will likely be closer to financial distress. Higher DE
firms would likely be harmed more by a requirement to disclose
environmental liabilities. Even firms with DE below, but near, 2.0 could
have a negative reaction to FIN47 as a new disclosure could lead to
failing test values. Negative reactions to FIN47 based on DE values
could also come via debt covenants. Firms near debt covenant limits
would have less financial flexibility and could face costly
restructuring. (We would like to thank an anonymous referee for pointing
out the possible affect on debt covenants.)
However, the relationship is not entirely clear. The higher DE, the
more often a firm will likely need to tap the banking sector or capital
market. Each round of financing brings scrutiny by analysts such that DE
can be used as a proxy for firm transparency (Almazan, Suarez, &
Titman, 2004). If so, higher DE firms may not see an impact from FIN47
as it is possible no new financial information will be forthcoming given
prior scrutiny (Jensen, 1986). In all, a negative relationship between
DE and CARs seems likely, but there may be no significant difference
between firms under or over the EPA's 2.0 guideline given the
transparency impact.
The EPA requires NIDEP/TL (which is, simply stated, a cash flow to
liabilities measure) to be greater than 0.10. We expect NIDEP/TL to be
positively related to abnormal returns since firms with less cash flow
relative to their liabilities should be hurt more if the companies must
report new CAROs. However, it is quite possible that firms with high
NIDEP/TL may not be impacted greatly if CAROs are a relatively small
amount.
The EPA test requires CR to be greater than 1.5. We expect a
positive relationship between CR and FIN47's announcement based on
the same idea as above that a firm in a worse financial position is
likely to be harmed more by additional CARO reporting requirements as
such revelations would likely be less of an impact for firms on stronger
financial footing. This same general pattern should hold for TNW
(tangible net worth), TNWCC (tangible net worth divided by the estimate
of closing costs), and NWCCC (net working capital divided by the
estimate of closing costs). For Z-scores, we expect a negative
relationship to CARs given that a lower Z-score is a predictor of an
earlier bankruptcy (or more current problems given higher bankruptcy
risks). For each of the above variables, we divide the companies into
two groups based on if the firm passes or fails the given EPA
requirement.
To take advantage of the SUR specification, we estimate Equation
(1) several times based on changing characteristics. First, we estimate
the model using the whole sample by differentiating between mining and
manufacturing firms. Then, we estimate the model for the different
industries by separating the sample into whether each firm passes or
fails the individual EPA financial assurance standards. Finally, we
combine the six separate EPA-inspired measures into an all-in variable
which separates companies which pass or fail the EPA standards. (We
calculate the overall EPA pass/fail variable using the EPA's first
test with conditions 1, 2, and 3 as stated above. We do not use
condition 4 as it requires the percentage of each firm's assets
located in the U.S. which is beyond our data source.) Equation (1)
enables us to test if the independent variables are significantly
different than zero as well as to test across portfolios for differences
in the variables such as the wealth effect (Ho: [[gamma].sub.1i] =
[[gamma].sub.2i]), and differences in systematic risk (Ho:
[[beta]'.sub.1i] = [[beta]'.sub.2i]).
RESULTS
Table 2 reports the results from estimating Equation (1). Both
regressions are highly significant with the systematic risk coefficient
on market return, [[beta].sub.i], being the main contributing
explanatory variable. The estimated equation explains 37.7% (85.4%) of
the variation in stock returns for the mining (manufacturing) firms
based on adjusted [R.sup.2] values. The market beta for the mining
(manufacturing) firms is significantly positive, as expected, with an
estimated coefficient of 1.48 (1.18). Thus, mining firms have nominally
higher systematic risk. The results also show a significant shift in the
systematic risk for the mining subset.
Of most interest, however are the tests for wealth impacts. Tests
based on [[gamma].sub.i]s show no significant change in wealth based on
the FIN47 announcement. There also is no difference in the
[[gamma].sub.i] values for mining versus manufacturing firms. Given the
discussion above, we believe it is possible that separating firms based
on financial characteristics may reveal underlying issues.
Table 3 compares the CARs based on the pass/fail values for various
EPA test variables. Our general expectation is that firms with variable
values showing the firm less able to pass will have lower CARs. Using
the whole sample, we do find firms with DE > 2.0, NIDEP/TL < 0.10,
and Z < 1.81--which means the firms fail those tests--have CARs
significantly less than 0.0. However, we also find firms with TNW >
$10 million, TNWCC > 6.0, and NWCCC > 6.0--which means the firms
passed those tests--have CARs significantly less than 0.0. However, only
in the case of comparing the CARs for TNW < $10 million as compared
to firms in the TNW > $10 million categories do we find a significant
difference between the two groups. Still, the test-passing group has the
lower average CARs.
We believe a plausible explanation is that the test-failing
firms' known financial bad news is such that investors do not
believe the possibility of reporting CAROs will harm the firm
significantly more. However, having to report CAROs might harm the
test-passing firms. This condition would explain why better firms react
with lower CARs.
To examine the impact from industry type, we repeat the above tests
from the whole sample, but divide the companies into mining and
manufacturing subsets. We, then, segment chemical firms from the
manufacturing group given chemical firms greater potential environmental
issues. In general, the most striking result for the mining and
manufacturing subsets is that there are few statistically significant
test results. However, the three significant test results are all in
keeping with firms with the test-passing results having negative CARs
(for TNW > $10 million for manufacturing) or the test-passing group
having significantly lower CARs than the test-failing group (for NWCC for mining firms and TNW for manufacturing firms).
The desirability of separating the chemical industry shows from the
eleven significant test results for that group. The DE and Z-score
values again have the expected negative relationship to CARs, although
there is no significant difference between the CARs for test-passing and
test-failing firms for either variable. In general, we also continue to
find results for NIDEP/TL, CR, TNW, TNWCC, and NWCCC that would support
the idea that passing firms in danger of becoming failing firms if they
must report CAROs, face likely higher costs. However, only for NIDEP/TL
are the test-failing firms' CARs significantly different from the
test-passing firms'. The possible explanation that the better firms
have more to lose, thus, gets further support.
Table 4 reports the results from estimating Equation (1) when we
sort the sample into firms which pass EPA standards as compared to those
which do not pass. The results for systematic risk ([[beta].sub.i]) and
the shift in the systematic risk for lagged returns for the mining
subset are the same as those reported in Table 2. Of greater interest
are the results for the tests on wealth impact ([[gamma].sub.i]) from
the FIN47 announcement. The [[gamma].sub.i] coefficient estimates for
firms passing EPA requirements are significantly negative both for the
"all firms" set and the manufacturing firms subset. Also,
F-test results show that the wealth effects are significantly worse for
firms which pass EPA requirements than for firms which do not. These
results are consistent with the explanation that passing firms are hurt
more by the possibility of having to report CAROs than non-passing
firms.
As a robustness check, we examine manufacturing firms known to have
environmental problems and included on the "Toxic 100" list
compiled by the University of Massachusetts Political Economy Research
Institute (PERI) for which we have the needed stock and financial
statement data. (The website for the PERI Toxic 100 list is:
http://www.peri.umass.edu/ToxicIndex.430.0.html.) We believe it is quite
likely that firms with known environmental issues will not suffer (or,
at least, not suffer as much) from FIN47's passage. Table 5 reports
the results from the 46 firms (21 passing and 25 not) in this data set.
We again estimate Equation (1) based on whether the firms pass the
EPA's test or not. We find no difference in the wealth effects
([[gamma].sub.i]) between those that pass or fail the EPA's test.
Thus, for those firms which already seem to have well-publicized
environmental problems, the FIN47 announcement does not have significant
wealth impacts. However, there is a shift in systematic risk for
EPA-pass firms and the increase in systematic risk is significantly
different than for non-EPA-pass firms. Taking this result along with
those in the earlier tables, we conclude that FIN47 is most likely to
impact firms which financial tests support as being in sound shape, but
for which investors fear unknown environmental issues as investors
appear to already have discounted the value of firms with known
environmental issues.
CONCLUSION
We examine the impact on mining and manufacturing firms' stock
returns from the announcement of the FASB's FIN47 March 30, 2005.
In general, we find marginally negative CARs, but with many returns
insignificantly different from 0.0%. When examining CARs relative to
financial variables utilized by the EPA, in general, we find firms with
better financial variables have lower stock returns. Separating firms
into mining and manufacturing firms shows little differences in wealth
impacts. It is possible that our generally insignificant findings for
mining firms could be related to the fact that their assurance process
differs from the average manufacturing firm. That issue is an avenue for
future research.
Comparing firms which passed EPA tests to firms which did not, we
find passing firms generally had lower stock returns than the
non-passing group. We interpret this result in regards to the financial
issue of transparency. Our results seem to indicate that investors
expect firms with known problems will not worsen in any significant way
while seemingly stronger firms may now have to report environmental
problems that had previously been undisclosed. Thus, the market's
reaction to FIN47 supports the idea that investors consider some
companies had not been fully disclosing potential environmental issues.
Comparing firms on a "Toxic 100" list provides added
support to the above argument. We find no difference between stock
returns for firms which do or do not pass the EPA's test
requirements. Thus, the specter of having to improve financial
transparency by reporting environment-related CAROs bring a wealth
impact to relatively stronger firms, but more so for those firms with
fewer existing environmental disclosures.

Table 1: Summary Statistics
The following table provides the summary statistics for the sample.
DE is the total debt to total equity ratio. NIDEP/TL is the (net
income + depreciation) divided by total liabilities. CR is the current
ratio (defined as total current assets divided by total current
liabilities) of the company. MV is the market value of the company in
millions of dollars. TNW is the tangible net worth (defined as total
assets minus total liabilities minus intangibles) in millions of
dollars. NWC is the net working capital (defined as total current
assets minus total current liabilities) in millions of dollars. PPE is
the net plant, property and equipment in millions of dollars. Finally,
Z-score is Altman's measure of bankruptcy prediction as computed by
Research Insight using Compustat data.
