Abstract:
The paper identifies which failures of corporate governance allowed non-financial companies
around the world to develop hedging strategies that led to hefty losses in the aftermath of the
financial crisis. The sample is comprised of 346 companies from 10 international markets, of
which 49 companies (and a subsample of 13 distressed companies) lost a combined U$18.9
billion. An event study shows that most companies that presented losses in derivatives
experienced negative abnormal returns, including a number of companies in which the effect
was persistent after a year. The results of a probit model indicate that the lack of a formal
hedging policy, no monitoring to the CFOs, and considerations of hubris and remuneration
contributed to the mismanagement of hedging policies. For heavily distressed companies,
there is evidence that higher ownership concentration implies in a lower probability of
designing speculative hedging positions.

Introduction
The purpose of this paper is to relate risk management and corporate governance by
analyzing the case of non-financial companies that posted hefty losses in derivatives trading
during the financial crisis that started in 2007. Dodd (2009) estimates that for 12 countries
that include Poland and economies of Asia and Latin America derivatives trading affected
possibly 50,000 firms, with losses totaling roughly $530 billion. Kamil, Sutton and Walker
(2009) present a small subsample of companies in Mexico (6 companies) with total losses of
U$4.7 billion (with an average loss of 23% of total assets) and 3 companies in Brazil with
total losses of U$5.5 billion - and an average loss of 46% of total assets.
There is one simple explanation for these losses: non-financial companies were hedging
financial positions – mainly currency exposures – and hence posted only book losses, with a
counterpart gain in revenue from the positions being hedged. However, this simple
explanation is insufficient to explain some relevant consequences from the disclosure of these
losses: many companies filed for bankruptcy; stocks plunged; some companies sued or were
sued by the banks that sold the derivatives contracts; accounting rules were changed (in
Brazil, India and China); and even the Chinese government's State-owned Assets Supervision
and Administration Commission (SASAC) got involved in trying to allow Chinese state-
owned companies involved in derivatives losses to walk away from contracts with
international banks (Reuters, 2009). The more plausible explanations are that companies
purposefully engaged in speculative positions and/or made mistakes in designing hedging
strategies involving derivatives to offset foreign-exchange exposure. Irrespective of which

explanation addresses the question of why companies committed mistakes in derivatives
trading, there remains the question of which corporate governance mechanisms failed in
allowing shareholders to monitor the behavior of executives who were able to design
destroying value strategies involving derivatives.
In this paper I evaluate the failures of corporate governance in monitoring risk management
strategies in a sample of non-financial companies that posted derivatives losses resulting from
the financial crisis. First, I show that the disclosure of losses stemming from derivatives
contracts by non-financial companies resulted in negative abnormal results which are a clear
indicator that the companies were either speculating with derivatives or made mistakes in
their risk management strategies. Then I use a probit cross-sectional model to compare the
corporate governance structure of companies that posted derivatives losses with companies
that did not by establishing a dependent binary variable in which for the companies that
posted hefty losses it assumes value 1 and for the control group zero. Since we have a clearly
defined event – the losses – the probit model is suitable to analyze which corporate
governance mechanisms failed in preventing executives from implementing value-destroying
financial strategies involving derivatives.
There is precious little empirical work done in the relationship between corporate governance
and risk management for cross-country companies. Disclosure issues and the difficulty of
arriving at usable data are partially responsible, but the lack of a comprehensive theoretical
framework also hinders empirical analysis. The present paper contributes to the literature in
many ways. First, it presents a comprehensive theoretical framework that explains why
4
international companies hedge. It then presents an analysis of a sample of companies that
posted heavy losses in derivatives trading on the wake of the recent financial crisis. Finally, it
relates these losses to failures in the corporate governance mechanisms of the selected
companies.
The structure of the paper is as follows: the first section describes in the research question
and main goal. The second section presents a theoretical discussion on the link between
corporate governance and risk management with the goal of developing a theoretical
framework that feed the next section, in which I develop the variables of the econometric
model and describe the data. The fourth section brings the results and analysis, while the last
section has some final comments.
I. RISK MANAGEMENT AND CORPORATE GOVERNANCE.
Tufano (1996) remarks (p.1097) that academics know remarkably little about corporate risk
management practices. Even though academia has catched up in the last 15 years [recent
models include Purnanandam (2008) and Fehle and Tsyplakov (2005)], we are still ignorant
on many risk management practices. Because risk strategies are not completely disclosed in
financial statements it is difficult to properly assess the extent of hedging policies and other
measures of risk management. In the present paper there is a clear event in which risk
management strategies are unveiled as a consequence of the financial crisis. The losses
posted by public companies and the effects on stock prices reveal a case of risk management
5
gone wrong and I exploit it by relating it to the corporate governance structures of the
affected companies in different markets around the world.
As for why companies use risk management strategies in the case of foreign-exchange
exposure, the main driver for a value-enhancing hedging policy is that in efficient markets
diversification transfer risks from the companies to the market. However, as Stulz (1996) and
Bartram (2000) show, to really generate value hedging policies have to deal with one of the
following possible gains: reductions in bankruptcy and distress costs, reductions in expected
tax payments, reductions in expected payments to stakeholders and/or reductions in costs of
raising funds. Moreover, when we add the perspective of management, canonical agency
theory models assume that egotistical agents maximize utility and thus corporate governance
should align this utility maximizing behavior with the interest of shareholders. Tufano (1996)
shows that two variables related to executives matter in determining if companies hedge or
not: the amount of shares owned by managers and the nature of the managerial compensation
contract. The author shows empirically that managers maximize their utilities through risk
management in two ways: if managerial wealth is affected by share prices companies hedge
substantially, with the converse being true – if management owns a small stake companies
hedge little; and if executive compensation involve options or similar features then managers
are more risk-prone and thus hedge less. More recent models, like Purnanandam (2008) and
Fehle and Tsyplakov (2005), expand the risk management theoretical literature by including
more sophisticated hypotheses, but the main results remain the same – risk management
should enhance value by dealing with one of the four characteristics present in Stulz (1996),
6
but is constrained by managers’ incentives given by executives’ ownership of shares and the
structure of managerial compensation.
Even though the combination of corporate finance theory and agency theory explains most
patterns in risk management practices, some recent literature has also been investigating the
impact of the institutional context on the behavior of management in designing hedging
policies. The main idea from behavioral finance is that managers are also affected by the
institutional environment in which executives are embedded (Wiseman et al, 2012, is an
example of a theoretical contribution that highlights the institutional impact on risk
management theory). This means that legal issues, stakeholders’ proactivity, corporate
governance and even managers’ innate characteristics also influence risk management
practices. For instance, Zhang (2009) argues that new transparency regulation in the
American market (SFAS 133) may have discouraged firms' speculative use of derivative
instruments; Bremer et al (2009) show that the provision of job security as a proxy for
employee interests has a significant effect on the likelihood of CFO dismissal and affect the
risk-taking behavior of CFOs, thus affecting possible hedging strategies; Indjejikian and
Matějka (2008) argue that firms mitigate earnings management or other misreporting
practices in part by deemphasizing CFO incentive compensation; Magnan et al (2008) find
that hubris (characterized by exaggerated self-confidence, arrogance and oblivion to reality
by executives) may be a critical factor to understand corporate financial frauds; and Dionne
and Triki (2005) find that better educated directors relate positively to better risk
management strategies and enhance corporate value. Regarding overconfidence as a possible
explanation for the miscalculation of risks by executives, Ben-David et al (2006) show how
7
CFOs build overconfidence by, among other factors, a focus on a recent series of past
successes. They also show that CFOs draw their “worst case scenario” from recent
realizations of the market and the firm, but upper confidence bounds are affected only by the
past 3-month stock market movement. The theoretical framework that I follow is the one
present in figure 1 below. On it, risk management and hedging policies are the outcome of a
combination of mechanisms based on finance theory, management incentives and the broader
institutional framework.
PLEASE INSERT FIGURE 1 HERE
In the present framework corporate governance is one of the main features of the institutional
framework that help shape companies’ hedging strategies. There are two ways in which the
corporate governance structure of a company reflects on hedging: monitoring and efficiency.
The monitoring aspect is clear because an effective corporate governance structure is
designed to prevent strategies that are against the interest of shareholders, usually preventing
speculative positions with financial instruments that are supposed to be used to hedge.
Specifically, non-executive directors are supposed to control risk-taking behavior or at least
align it to the interest of shareholders. This point relates to efficiency seeking by allocating
company resources to create value. However, in the case of risk management, speculative
positions create value by exploiting private information in the hands of the company, but
there are two conditions for this to be carried out: internal transparency and private
information.

The empirical evidence on derivatives usage, however, shows unequivocally the relevance of
such instruments for non-financial companies. Earlier studies [e.g. Bodnar et al. (1995);
Phillips (1995); Berkman and Bradbury (1996); Berkman et al. (1997); Howton and Perfect
(1998); Bodnar et al. (1998); De Ceuster et al. (2000); Mallin et al. (2001)] analyze the
patterns of derivatives usage and its determinants, showing widespread usage of derivatives
by non-financial companies and its relevance to corporate risk management. More recently,
Bartram et al. (2009) show that, in their sample of 7,292 non-financial companies from 48
countries, 59.8% of the companies use derivatives in general, while of those mostly use
currency derivatives, followed by interest rate derivatives and commodity price derivatives.
Also, other than the size of the local derivatives market no other country-specific factor is
significant, while the companies hedge for risk management purposes and not speculation.
Regarding the risk management theory based on corporate finance, Bartram et al (2009) find
that companies are in line with the financial distress hypotheses, and tests indicate that
derivatives users have significantly higher leverage and income tax credits as well as lower
liquidity (as measured by quick ratios and coverage ratios). However, the authors also arrive
at some evidence that runs counter to corporate finance theory - specifically, more profitable
firms and firms with fewer growth opportunities (market-to-book ratios) tend to hedge more.
There is no explicit theory that relates corporate governance and risk management since the
theoretical background uses theories from corporate finance and agency theory, as previously
observed, but Dionne and Triki (2005) present some interesting empirical results regarding
CFOs personal characteristics. They establish a relationship between corporate hedging and
9
the background and education of the board and the audit committee members. The authors
find that financially educated directors seem to encourage corporate hedging while
financially active directors and those with an accounting background play no active role in
hedging strategies. Dionne and Triki (2005) also find a positive relation between hedging and
firm performance, suggesting that shareholders are better off with financially educated
directors on their boards and audit committees.
II. HYPOTHESES, DATA AND METHODOLOGY.
II.A - Data Description.
Hundreds of companies posted losses with derivatives during the financial crises. However,
in most countries there is no duty to report risk management strategies, and most companies
with losses are not listed companies. Also, many losses were rolled over a number of periods,
were negotiated with banks or information was never made public. Because of such
constraints, data for the present paper were hand collected following three criteria: losses
should have been public, thus posted in the media through newspapers, websites, magazines
etc; financial statements should reveal those losses; finally, data on the corporate governance
structure of the companies (described in section 3.2) should have been able to be constructed.
The idea behind using news media as a source of information has a long tradition in empirical
research, leading to the development of the methodology of event studies, which is used to
analyze abnormal stock returns given some new publicly available information.
10
The final sample has 49 companies in 10 financial markets (Australia, Brazil, China, Hong
Kong, India, Indonesia, Japan, South Korea, Mexico and Poland). Companies did not post
losses in the same period due to different accounting systems and the timing of the financial
crisis, hence I use for each company and the other companies in the same market the financial
year in which losses are revealed. The earliest period in the sample is June of 2008 for Indian
companies and the latest March of 2009 for some Chinese companies. I treat this window as a
single event for the purpose of relating it to the corporate governance structure of the
companies at this and earlier periods and for the event study. The 49 companies in the sample
lost a combined U$18.9 billion. Table I below presents figures for the absolute losses and the
ratio between the losses and revenues, as well as market capitalization. We can see that losses
affected small and large companies and it did not discriminate by developing or developed
markets or by regions – the sample include companies from five continents and the range of
revenue is U$26 million (C-Motech from Korea) to U$33.7 billion (China Railway Group).
Even though the sample is heavily skewed towards industrial and exporting companies that
present foreign exchange exposure, it also presents companies that were hedging other risks,
such as oil prices.
PLEASE INSERT TABLE I HERE
Losses as a percentage of revenue range from 0.6% to 88.1%, while as a share of market
capitalization from 0.9% to 651%, which shows that companies are impacted in different
ways. Because of this I create a subsample composed of companies that experienced major
distress. Major distress is defined as bankruptcy, acquisition by another company, major asset
11
sales (Win4Net had to sell its headquarters building) or a restructuring of derivative contracts
with banks to avoid a default on the contracts. This subsample includes 14 companies (APN
Property, Aracruz, Sadia, Citic Pacific, Win4Net, C-Motech, Taesan, Baiksan, Kalbe Farma,
Controladora Mexicana, Gruma, Vitro, Ropczyce and Odlewnie Polskie).
II.B - Event Study.
The idea behind the event study is to verify if the losses by the sample companies can be
regarded as value destroying. If the risk management strategies were sound companies should
only suffer accounting losses and there should be no effect on stock prices. Here I follow the
standard methodology summarized in MacKinlay (1997). The main caveat is that there is no
precise way to define the exact period for the analysis since it is based on the date in which
the media reported the event. For each company the event starts at time 0. As usual I present
results for 7, 60 and 360-day windows. The abnormal rate of return (ARit) is the difference
between the actual return (ri,t+e) and the forecast rate of return (^
r i,t+e):
The average and variation equations are based on Corhay and Tournai (1996), a GARCH
model that accounts for time-varying volatility effects. Variables t and 1ith are
respectively the information set at time t for firm i and the conditional variance. Equations
are:

Results are in table II. The patterns we can see are: for distressed companies 11 of 14
companies show significant negative abnormal returns in the first day, an effect that is
persistent for 10 companies one year later. For the non-distressed companies 21 of 35
companies present abnormal negative returns in the first day, but only 7 companies still
present negative returns after one year. The sample companies use value-destroying hedging
strategies, a result that was persistent over a period of time.

II.C - Hypotheses.
The hypotheses for the econometric testing follow the theoretical framework presented in
figure 1. Since the main objective is to relate corporate governance and risk management I
build hypotheses regarding how the governance structure of a company can impact the design
of hedging strategies. Relating the theoretical framework to workable hypotheses is
conditional on building variables that are constructible from financial statements and public
information on the corporate governance structure. I use previous research and focus on the
role of the CFO and the underlying structure that allow the design of misplaced hedging
strategies. Unfortunately, unlike Dionne and Triki (2005), I have no data on the background
of executives, but a comprehensive study of the companies’ governance structure yields other
)2(, ithtihmtiit rrCr
)3(),.,0(~ ,,2
1 jtiijktiikiititit hhdhN
13
qualitative indicators of the relationship between governance, agency theory and risk
management. The following hypotheses are tested in the econometric model:
H1: No monitoring (MON): Lack of proper CFO monitoring increases the probability of
leveraged positions in derivatives.
In many companies the CFO is directly responsible for designing and monitoring the risk
management strategy, presenting the results to the board. No good monitoring of the CFO’s
strategies can have a real impact, as exemplified by the Brazilian company Sadia. The
company redesigned its governance structure right after disclosing its losses in 2008. Figure 2
shows the old and the redesigned governance structure regarding its risk management
strategies. As we can see, the old structure gave too much discretionary power to the CFO,
because he was responsible to monitor the strategy and present the no compliance report to
the rest of the Board. Data for MON is binary and come from the financial statements of the
companies. It assumes value 1 for companies in which the CFO is responsible for managing
and answering for the risk management strategy and 0 otherwise.
PLEASE INSERT FIGURE 2 HERE.
H2: Disclosure (DIS): Disclosure leads to better monitoring by shareholders and less
probability of leveraged positions in derivatives.
14
Financial disclosure rules are different worldwide. In the United States the standard for
financial reporting of derivatives, SFAS 133 Accounting for Derivative Instruments and
Hedging Activities, went into effect in 2001 and presents a series of compulsory financial
disclosures such as differentiating between hedging and speculation and requiring derivative
contracts to be marked-to-market and recorded as assets or liabilities on the balance sheet.
Derivatives used in speculation are marked-to-market with gains or losses realized in the
current period's income. For many countries, such as Brazil, India, and China, disclosure on
derivatives dealings was optional before the crisis, with most companies choosing to share
minimal or no information. In Brazil, the regulatory agency requested, in October 17th
2008
and weeks after the first news regarding the hefty losses of companies such as Sadia and
Aracruz, that public companies disclose more information on derivatives. Since then further
regulations have been enacted to tighten the disclosure of such information, with CVM
(Comissão de Valores Mobiliários) requesting account restatements of some companies
regarding derivatives trading in 2010. I build a qualitative binary variable regarding the
quality of disclosure of derivatives information. Data come from the notes of the financial
statements of the companies.
H3: Shares in the American Market (USA): Compliance with SEC rules leads to better
monitoring by shareholders and less probability of leveraged positions in derivatives.
If a company has shares in the American market it has to disclose its derivatives dealings,
which provides even more opportunities for shareholders’ monitoring. USA is a binary
15
variable, assuming value 1 when the company does not have shares in the American market.
Data come from the companies’ websites.
H4: Concentration (CON): Higher ownership concentration enhances monitoring and
decreases the probability of leveraged positions in derivatives.
Ownership concentration is a standard variable in empirical corporate governance studies.
Even though dispersed capital enhances value, it creates monitoring problems in relation to
risk management strategies. CON is here defined as the proportion of shares in the hands of
the three major shareholders, hence it is a continuous variable in the (0,1) interval. Data come
from Datastream and Compustat Global.
H5: Institutional Investors (IIN): Institutional investors in the Board enhance monitoring
and decrease the probability of leveraged positions in derivatives.
Participation of institutional investors on the board should help monitoring of financial
management. Data for the binary variable come from the financial statements or companies’
websites.
H6: Formal Hedging Policy (FHP): lack of a formal hedging policy increase the probability
of leveraged positions in derivatives.
16
Many companies specify a formal hedging policy – Air China, for instance, hedge at most
50% of its oil costs. Such policies should be a determent for speculative positions in
derivatives. Data for the binary variable come from the financial statements or companies’
websites. Variable assumes value 1 when the company has a policy in place and 0 otherwise.
H7: Trend of Major Source of Risk (TRE): a clear trend on the risk being hedged increase
the probability of a leveraged position in derivatives.
Hubris is the most difficult proposition to test for regarding agency theory, since it is almost
impossible to prove intent. I provide two indirect measures that account for the possibility of
hubris through the creation of an environment conductive to overconfidence, following Ben-
David et al (2006). The first is a medium-term trend in the risk being hedged. Years of
currency appreciation, for instance, may build confidence in leveraged positions in
derivatives to exploit the continuation of the trend. The variable is designed as the linear
trend of the underlying risk in the last 3 years, which means that for Brazilian companies it is
the linear trend of the Real, for Korean companies the Won, and for companies that were
hedging oil prices it is the trend of oil (Brent) prices.
H8: Recent Financial Results (FIN): recent financial gains increase the probability of a
leveraged position in derivatives.
The second variable pertaining to an indirect indication of hubris is a qualitative binary
variable that represents the last three quarter of financial results. It indicates if the company
17
posted better than market-average financial results, and assumes value 1 only if the result of
the company beat the market in all three previous quarters. The idea is that, following Ben-
David et al (2006), positive reinforcement breeds overconfidence. Data come from financial
statements.
H9: Remuneration (REM): a remuneration package for the CFO that is based on short-
term incentives increase the probability of a leveraged position in derivatives.
The variable relate to the design of the remuneration of the CFO. If remuneration is tied to
medium-term performance, it assumes value 0, otherwise it assumes value 1. The rationale is
that short-term incentives are tied to excessive risk-taking. Data come from companies’
websites and corporate governance reports.
H10: Management Stake (MAN): Higher management stake increase the probability of a
leveraged position in derivatives.
Following Tufano (1996), MAN is a continuous variable that is the average of the
management stake in the previous three years.
Variables relating to independent directors and CEO duality, which are usually a mainstay of
corporate governance studies, were dropped because of poor predictability in the model. It is
safe to argue that those variable show a poor relation to risk management strategies, since
neither independent directors nor CEOs as Chairman of the Board would, in principle, be able
18
to curtail or give incentives of excesses in risk management strategies just by being
independent or by acquiring a dual role in a company. Even though independent directors and
CEOs who are not Chairmen of the Board are usually figures that result in better governance
in the literature, in the present case we cannot see how they impact in a better risk
management monitoring role. The failures in risk management seem to be institutional in
nature in the present case. If incompetence plays a role, it is not one borne out of the role of
independent directors and CEOs as Chairmen, but it is the result of Directors, including the
CFOs, who weren’t able to curtail excesses in risk management strategies regardless of their
inherent role in the companies.
II.D - Probit cross-sectional model.
The dependent variable of the model that tests the relationship between corporate governance
and risk management is a binary variable which assumes value 1 for the companies that
posted derivatives losses and value 0 for companies that did not. The selection process of
companies for the test is very simple: public companies from the same market and industry as
the companies that posted losses, restricted by data availability. As an example, for the
Brazilian market the selection comprises 30 companies from petrochemical, steel, food, pulp,
and textile industries. For the 10 international markets the total of selected companies,
including the sample, is 346. Since the dependent variable is binary, the resulting model is a
probit cross-sectional model. The general model is given by equation 1, in which C is the
vector of controls and D the vector of sector dummies:
19
0''

7654321
i
iDCMANREMFIN
TREFHPIINCONUSADISMONY
(1)
The resulting control vector (after iterations of the model with other financial variables) is
composed of:
Family-Owned: binary variable, resulted from hand-collected data;
Age: continuous variable with data coming from the companies’ websites;
Leverage: continuous variable based on the average financial debt ratio for the last three
years. Data came from financial statements.
As for dummies, I used market dummies in the first round of estimation, one for each
international market, but none improved the models. I dropped it in presenting the final
results.
The error term should capture all variation that is not explained by the selected variables. It is
impossible to perfectly model risk management decisions. In the present context we cannot
expect that the constructed variables can capture all the decision making process regarding
the losses in derivatives. The cognitive process that leads to decision making is truly multi-
dimensional and the present variables can at most capture the incentives that may lead to the
decision to overhedge or speculate with derivatives. Ideally one should have very descriptive
data on the risk management department and the CFO characteristics, plus its relationship
with the Board. Since such data do not exist or is unavailable, we should not expect an
20
overtly fit model to the available data, even though the theoretical framework presently
developed should be appealing.
III – RESULTS AND ANALYSIS.
I divide the results in two, one for the whole sample of 49 companies and one for the
distressed sample composed of 13 companies. For both samples the dependent variable
assumes value 1 for affected companies that lost in derivatives and value 0 for the other
companies in the sample. The main diagnostic test is the cross-dependence (CD) test based
on Pesaran (2004) and Hsiao et al (2007) that indicates independence across the sample (it is
based on the Lagrange Multiplier, and the null hypothesis is for cross-section independence -
H0 : R = IN).
The probit econometric model is run using STATA 10.0 and is based on equation 1. Some
sensitivity analyses are also performed. In particular, many other controls are used in first
trials of the model, such as liquidity, price/earnings ratio and other financial variables. All
financial variables other than leverage result in poorer modeling performance and are
dropped. Market dummies are also dropped due to poor performance. Table II presents the
econometric results and table III the marginal effects of the probit model. Controls are
omitted for brevity, but no control other than financial leverage (and only for distressed
companies and even so, marginally) is significant.
21
PLEASE INSERT TABLE III HERE.
PLEASE INSERT TABLE IV HERE.
Results for the whole sample show that corporate governance plays an important role in the
design of risk management strategies (in the present case, the dependent variable when it
assumes values 1 represents mismanagement of derivatives), as does the trend of the source
of risk and the remuneration incentives of the CFO. For the whole sample three hypotheses
relating to corporate governance are statiscally significant: lack of formal monitoring
structures (MON); shares in the American market (USA); and formal hedging policy (FHP).
All post the expected sign, with lax monitoring resulting in higher probability of leverage
with derivatives, and shares in the American market and formal hedging policy acting as
deterrents to mismanagement of such instruments. The marginal probabilities are not
particularly high, but are significant nevertheless. No monitoring structure enhances the
probability of mismanagement of derivatives, in the present model, in 2.3%, while shares in
the American market and a formal hedging policy decrease the probability by 1.9% and
1.2%, respectively. Hypothesis 2 - disclosure does not present a significant impact, and its
explanation is that most companies in a single market usually follow the same disclosure
rules and thus we can conclude that voluntary disclosure is lacking in the markets analyzed.
Hypothesis 7, relating to the trend of source of risk variable posts an interest result. It is an
indicative of an incentive to overconfidence by building strategies based on previous results.
It was certainly used as an explanation in the media by executives – in an interview the CFO
of Companhia Siderúrgica Nacional of Brazil dismissed the hefty losses by arguing that the
derivatives strategies have netted sufficient gains in the past to make it worthwhile, even if
22
shares dropped heavily after the company’s losses were announced. As for hypothesis 9,
remuneration, it clearly shows that there is an incentive for CFOs to hedge more if their
compensation is tied to short-term performance, as the probability of hedging increases with
this incentive.
Results change somewhat when we consider the sample with distressed companies.
Monitoring and shares in the American market are not significant anymore while
concentration and management stake play a role in the case of companies who suffered the
most with derivatives losses. Hypothesis 4, concentration, does not present the expected sign.
It is expected that market monitoring through dispersed shares enhances the probability of
giving the correct hedging incentives, but the results show that higher concentration
decreases the probability of major distress in derivatives dealings by 1.5%. In the markets
that comprise the sample there is a culture of ultimate owners with high levels of control,
which results in more incentives to monitor high leverage. In fact, the same reason that makes
academics argue that dispersed companies are in general more efficient may have resulted, in
the specific case of speculation with derivatives, in a more risk-taking position by managers,
in contrast with the usually more cautious and centralized approach when a company has a
single or a small group of owners. Also, the result corroborate Tufano (1996), since both
reasons raised by the author, represented in the present sample by remuneration and
management stake, are statistically significant.
23
III.A - Implications for the Regulation of Financial Markets.
The results are especially significant if we think in terms of regulation of stock markets.
Ultimately shareholders and stakeholders shared the burden in the losses by the companies.
The results of the two models show that skewed incentives for the managers coupled with
some lax governance structure (especially a formal hedging policy and no monitoring)
contributed to the companies’ mismanagement of the hedging policies. There are two
important implications: we can argue that it is the responsibility of shareholders to effectively
monitor the companies’ strategies and hence the issue was not one of a market failure or lack
of regulation; or we can argue that for incipient and developing markets the evolution of
regulation should embody rules and codes that prevent the possibility of the design of
possible deleterious strategies. Since we find no evidence of mismanagement, in the context
of the financial crisis, in the American or other developed markets, it may be assumed that
market failures in developing countries contributed somewhat to the effects experienced by
these companies. If we take the example of Brazil, in which the regulatory agency (CVM –
Comissão de Valores Mobiliários) requested ex-post that companies disclose their derivatives
position, we can see a reaction to an acknowledgement that transparency played a role. Even
though I found no evidence that transparency was statiscally an issue – after all, companies
that did not lose with derivatives were not compelled to disclose their position – we can go
beyond the simple transparency prescription to address issues of the design of corporate
governance structures. As figure 2 shows, the checks and balances of risk management
strategies were more important than simple disclosure issues. Not only investors can learn
from what happened with these companies, but the regulatory agencies now have subsidies to
24
request formal structures that comply with a situation in which companies should not be
allowed to unwittingly speculate with derivatives. In developing markets corporate
governance structures matter more than in mature markets – hence the development of
features like the New Market (Novo Mercado) in Brazil. It should be the purpose of the
regulator to help shareholders prevent hubris and incompetence from hurting not only
companies, but as we can see from the hefty losses, whole markets.
Can markets alone prevent developments like the positions in derivatives that bankrupted
some companies and yielded major losses to others? If markets are truly efficient the
leveraged position of companies is already part of the shareholders’ portfolio. However, we
know that earlier derivatives lessons, like the one from Metallgesellschaft (MG) - which
posted losses of over U$1 billion in the mid-90s, have not prevented companies around the
world to leverage their positions, intentionally or not, in these instruments. In developing
markets regulation is supposed to foster a better business environment, especially because
information asymmetry and lack of liquidity prevent full market efficiency. In the case of
non-financial companies, regulations like the one in Brazil which now requires better
disclosure of derivatives positions, is a step forward in that direction. However, regulators
should also recognize that disclosure alone is insufficient. As we can see from the results,
hubris may have played a role, as did skewed incentives to management through
remuneration and management stakes. Moreover, the simple lack of a formal hedging policy
(Air China had one in place which allowed management to hedge at most 50% of oil costs)
also contributed to these losses. In fact, not all the losses were derived from speculative
positions, but in all cases it caught management and investors unaware, and such failures
25
should be avoided in the future. Better governance regulation imply, for instance, changes in
the relationship between monitoring of risk management strategies, while leaving for
shareholders to devise correct incentives for CEOs in relation to risk-taking positions.
IV. FINAL COMMENTS.
The main goal of the paper was to establish a relationship between corporate governance and
risk management by focusing on the case of companies that posted heavy losses in
derivatives during the financial crisis. I built a sample of 49 companies from 10 international
markets, from Latin America, Europe, Asia and Oceania. The combined losses of these
companies were a combined U$18.9 billion. Moreover, 13 of these companies went into
bankruptcy or suffered heavy restructuring, being acquired by other companies and such.
For the purpose of relating corporate governance and risk management first I built a
theoretical framework that encompasses regular finance models with agency theory and
behavioral finance. To test hypotheses concerning this theoretical framework I hand-collected
data on many qualitative indicators of corporate governance, proxies for hubris and other
management characteristics such as the remuneration scheme and the stake of management in
the companies. The empirical testing through a probit cross-sectional model reveals that some
corporate governance characteristics, such as the inexistence of formal hedging policy, lax
monitoring of the risk management department and dispersed ownership concentration are
relevant to the mismanagement of derivatives instruments. Results also show that variables
26
relating to overconfidence and incentives to executives are also relevant. The main impact of
this study is related to the regulation of stock markets – it clearly shows that the failures in
risk management are due to reasons not only related to transparency. In fact, the first
response by market regulators to the distress of many companies was change disclosure
policies regarding derivatives instruments. While better disclosure policies is probably
effective in allowing shareholders better monitoring, we can clearly see from the results that
the losses experienced by the selected companies resulted from more complex issues than
that. Since the analyzed markets are mostly in developing countries, with relevant issues like
imperfect and asymmetric information being part of the environment, regulators should look
into designing policies that correct incentives for proper risk management by non-financial
companies.
Several avenues of research remain. This study only analyzed a sample of 49 companies in a
cross-sectional study. Future research should complement the present one by focusing on the
evolution of risk management strategies. Are companies devising better governance
structures to curb future losses? The finance literature is full of examples of companies that
posted hefty derivative losses, and still companies around the world lost an estimated U$500
billion during the financial crisis. As other markets develop, new companies enter and history
is forgotten there is no guarantee that a new cycle of derivatives losses will not happen.
Social welfare should not be affected by events like this, but in many developing markets
widespread losses lead to less liquidity and hamper the development of capital markets.

structure allowed too much discretion to the CFO, while the new structure reveals better governance for risk
management. Sadia was acquired by its main competitor, Perdigão, in May of 2009. The resulting company is
called Brasil Foods. In 2006 Sadia attempted a hostile takeover of Perdigão but was not successful.

Table II -Abnormal Daily Stock Market Performance after Announcement of Derivative Losses.
Table II reports cumulative abnormal return (CARt) up to the specified day t in event time. Column 1 has each
company, followed by the market, the date that the media announced the derivative loss of each company. Column 4
is the stock return on the day of announcement. Event time is days relative to the media announcement of derivative
losses. Abnormal returns are computed given the market model parameters which are estimated with the GARCH
model ithtihmtiit rrCr ,
through the period [-190; -10] in event time, where rit is the continuously
compounded local return on date t in country i and rmt is the continuously compounded daily market return on index
on day t. The sample period runs from 90 trading days before the date in the third column to the dates in columns 5 to
8. Values in bold are statistically significant at 5%. Table is divided in two categories: major distressed companies and
non-distressed companies. Major distress is defined as bankruptcy, acquisition by another company, major asset sales
or a restructuring of derivative contracts with banks to avoid a default on the contracts. Company Market Date Day 1 t=0 t=7 t=60 t=360
