Trang 5Abstract
The objective of this thesis is to investigate the corporate governance attributes of smaller listed Australian firms This study is motivated by evidence that these firms are associated with more regulatory concerns, the introduction of ASX Corporate Governance Recommendations in 2004, and
a paucity of research to guide regulators and stakeholders of smaller firms While there is an extensive body of literature examining the effectiveness of corporate governance, the literature principally focuses on larger companies, resulting in a deficiency in the understanding of the nature and effectiveness of corporate governance in smaller firms
Based on a review of agency theory literature, a theoretical model is developed that posits that agency costs are mitigated by internal governance mechanisms and transparency The model includes external governance factors but in many smaller firms these factors are potentially absent, increasing the reliance on the internal governance mechanisms of the firm Based on the model, the observed greater regulatory intervention in smaller companies may be due to sub-optimal internal governance practices Accordingly, this study addresses four broad research questions (RQs) First, what is the extent and nature of the ASX Recommendations that have been adopted by smaller firms (RQ1)? Second, what firm characteristics explain differences in the recommendations adopted by smaller listed firms (RQ2), and third, what firm characteristics explain changes in the governance of smaller firms over time (RQ3)? Fourth, how effective are the corporate governance attributes of smaller firms (RQ4)?
Six hypotheses are developed to address the RQs The first two hypotheses explore the extent and nature of corporate governance, while the remaining hypotheses evaluate its effectiveness A time-series, cross-sectional approach is used to evaluate the effectiveness of governance Three models, based on individual governance attributes, an index of six items derived from the literature, and an index based on the full list of ASX Recommendations, are developed and tested using a sample of 298 smaller firms with annual observations over a five-year period (2002-2006) before and after the introduction of the ASX Recommendations in 2004
With respect to (RQ1) the results reveal that the overall adoption of the recommendations increased from 66 per cent in 2004 to 74 per cent in 2006 Interestingly, the adoption rate for recommendations regarding the structure of the board and formation of committees is significantly lower than the rates for other categories of recommendations With respect to (RQ2) the results reveal that variations in rates of adoption are explained by key firm differences including, firm size, profitability, board size, audit quality, and ownership dispersion, while the results for (RQ3) were inconclusive With respect to (RQ4), the results provide support for the association between better governance and superior accounting-based performance In particular, the results highlight the importance of the independence of both the board and audit committee chairs, and of greater accounting-based expertise on the audit committee In contrast, while there is little evidence that a majority independent board is associated with superior outcomes, there is evidence linking board independence with adverse audit opinion outcomes These results suggest that board and chair independence are substitutes; in the presence of an independent chair a majority independent board may be an unnecessary and costly investment for smaller firms

Chapter One Introduction
1.1 Introduction
There has been considerable public, investor and regulatory interest in corporate governance issues over the past 20 years This interest has been created by a number of stimuli, including increased fluidity of global capital, corporate failures, the need to improve investor confidence, and recent poor public perception of corporate accountability In response to these stimuli, market regulators across the globe have undertaken reforms of corporate governance requirements, usually taking the form of development of codes of conduct or best practice guidelines
A spate of corporate failures in 2001, both in Australia and overseas, led the Australian Stock Exchange1 (ASX) to form the ASX Corporate Governance Council (ASXCGC) develop and deliver an industry-wide, supportable and supported framework for corporate

Good Corporate Governance and Best Practice Recomme
which became effective for listed companies from reporting dates after 1 January 2004
The ASX first required companies to disclose their corporate governance practices when Listing Rule 3C(3)(j) became effective for reporting periods ending on or after 30 June 1996 This rule required listed companies to disclose their main corporate governance practices in place during the reporting period The ASX opted for a non-prescriptive approach with the subsequent introduction of recommendations owing to concerns that smaller companies might be overwhelmed by the burden of compliance (Ramsay and Hoad, 1997) Concerns about the cost of compliance with corporate governance codes for smaller companies have been a feature of debates in other jurisdictions In the context of the UK market, Peter (2005,
Trang 242
While the major principles of good corporate governance are of relevance to all companies, it would be a mistake to believe that every aspect of the detail of what is promulgated for large listed companies is relevant across the spectrum In order to achieve acceptance and eventually enthusiasm for corporate governance the principle must be relevant to the size, structure and nature of the business entity
number of smaller companies (Ramsay and Hoad, 1997), and the debate regarding how corporate governance requirements should apply to these companies has been robust The objective of this thesis is to investigate the nature and effectiveness of corporate governance
in smaller listed Australian companies
1.2 Motivation
This thesis is motivated by several factors First, despite the debate over how corporate governance codes should apply to smaller companies, there is comparatively little empirical evidence related to the corporate governance environment of smaller companies, and the efficacy of governance mechanisms in these firms Reasons for the lack of empirical evidence include the economic significance of the largest companies and the availability of data for these firms This thesis addresses this gap by examining the governance structures of smaller Australian firms
Second, despite the lack of research focus on smaller companies, there is evidence that smaller companies create more regulatory concerns Smaller listed Australian companies receive a disproportionately high number of ASX queries regarding large, unexplained share price movements (Neagle and Tsykin, 2001) Smaller companies in the US are also associated with a higher number of regulatory interventions for breaches of accounting standards (Dechow, Sloan and Sweeney, 1996) This evidence of adverse outcomes for smaller firms provides the second motivation for exploring the governance environment of smaller firms
Third, the introduction of the ASX Recommendations in 2004 provides an opportunity to examine how smaller companies have approached the commencement of a new governance code and to determine if the new code has caused smaller firms to review and amend their corporate governance policies and mechanisms More specifically, this thesis investigates the extent of adoption of individual recommendations and examines the principal factors associated with the governance choices of smaller firms Where changes in corporate
Trang 251.3 Corporate governance in smaller firms
Effective corporate governance measures act to reduce the agency costs that arise from the information asymmetries caused by the separation of ownership and management The agency conflict is central to Shleifer and Vishny (1997) description of corporate governance
C governance is a broad term given to the disparate forces and mechanisms that direct and influence the operations and management of a company A commonly cited definition is
originating in the Cadbury Committee report (1992: para 2.5) Yet, these definitions and others seemingly overlook the complexity of corporate governance and its influences and mechanisms The Organisation for Economic Co-operation and Development (OECD) takes a more holistic approach and describes corporate governance as a set of relationships between
I structure through which the objectives of the company are set, and the means of attaining
OECD T OECD definition takes a broader view of governance, in contrast to the narrower definitions focused
on control or suppliers of finance
The ASXCGC (2003, p 3) also uses a broad approach that incorporates the notion of accountability by defining corporate governance as:
objectives of the company are set and achieved, how risk is monitored and assessed, and how performance is optimised Good corporate governance structures encourage
Trang 264
commensurate with the risks involved
From these definitions corporate governance is viewed not merely as the internal policies and procedures of organisations, but as a broader concept including the legal and social
that incorporates relationships with stakeholders who may or may not interact directly with the business entity Expanding on this point, it is evident that governance mechanisms and influences separate into two broad categories: those imposed from the external environment
in which the firm operates, and those that are established within the firm to provide guidance
on how the board and managers conduct the business of the firm
1.3.1 The external governance environment
All companies are subject to the scrutiny and influence of a range of stakeholders These include regulatory bodies such as the Australian Securities and Investments Commission (ASIC) and the Australian Securities Exchange (ASX), and information intermediaries such as analysts,
substantially more scrutiny by information intermediaries than their smaller counterparts Analysts mainly focus their resources on larger companies as the stocks of these companies comprise the majority of market indices Institutional investors also focus their resources on stocks in the major market indices While debtholders can influence the behaviour of companies and their boards through contracting arrangements, many smaller companies are unable to obtain debt finance Although the media plays an important role in disseminating information and reducing information asymmetries (Bushee, Core, Guay and Wee, 2006), smaller firms receive much less coverage Smaller companies are also less likely to retain the services of a Big 4 audit firm, a common proxy for audit quality Table 1 summarises key factors influencing the external governance of firms, considers their impact, and illustrates how the influence of external stakeholders varies with company size

Institutional Investors Higher ownership and
related to measures of its size In addition, analysts and media can effectively act as de facto
sources of regulation for larger companies by directing the attention of regulators to individual companies3 In contrast, regulation of smaller listed companies in Australia is generally limited
to the formal scrutiny of the ASX and ASIC In the absence of many of these external governance influences, the flow of information to shareholders of smaller companies will be restricted, as demonstrated in Figure 1.2 The absence of these formal and informal external factors may also lead to weaker internal governance if substitute mechanisms are not available The differences in the information and governance environments for smaller companies and their impact on performance, though evident in the literature, are rarely explicitly examined
3 For example, on 6 June 2006 The Australian published an article regarding the potential liability faced
by a subsidiary of Lend Leas A allegedly caused by toxic fumes and dust released during its clean-up of Ground Zero after the September 2001 terror (West, 2006) The company subsequently made a market disclosure, to avoid possible action for breach of continuous disclosure For small companies, not subject to media scrutiny, such publicity is less likely

1.3.2 The internal governance environment
The internal governance of firms consists of the mechanisms, processes and procedures established to oversee and influence the a T
governance is to ensure compliance with corporate law and stock exchange listing rules relating to disclosure and financial reporting, and to safeguard against behaviour such as earnings management or excessive consumption of perquisites (Davidson, Goodwin-Stewart and Kent, 2005; Dechow, Sloan and Sweeney, 1996) An effective internal governance structure will ensure that markets are informed through the timely disclosure of firm specific information, and will also minimise agency costs, potentially leading to better performance
The weaker information environment for smaller firms, together with the potential absence of external governance actors, raises concerns about the overall governance environment of these firms Where the internal governance structures and attributes do not adequately substitute for the deficiency in external monitoring, then there may be adverse consequences for these smaller firms
1.4 Research objectives and research questions
There is a vast body of research literature exploring corporate governance and its associations with a range of firm outcomes However, much of the literature centres on larger companies, with relatively little attention paid to smaller firms The broad objective of this study is to extend the governance literature to smaller firms, and more specifically, to smaller listed Australian firms Owing to differences between firms of different size, the findings of earlier corporate governance studies may not be generalisable to smaller firms
When the ASX Recommendations were introduced, the ASXCGC noted that the range in size and diversity of companies is significant and that companies should determine if each recommendation is appropriate to its particular circumstances (2003, p 5) In addition, they noted that smaller companies may not derive efficiencies from the formation of board committees (2003, pp 22, 30, 43, 54) Given the diversity of listed companies, the non-prescriptive nature of the recommendations, and the guidance on committee formation, it is expected that variations in the rate of adoption of the recommendations will be observed Hence, the first research question asks:
Trang 308
RQ1 What is the extent and nature of the ASX recommendations that have been adopted
by smaller listed firms?
There is an expectation in the first research question that considerable differences will be found in the rates of adoption of the various ASX recommendations An extension of this question is to consider the factors that may explain the governance choices of these firms As discussed above, guidance from the ASXCGC suggests that board committees may be less common in smaller firms However, firm size may only be one factor associated with differences in the adoption of the recommendations Therefore, the second research question asks:
RQ2 What firm characteristics explain differences in the ASX Recommendations adopted by
smaller listed firms?
While the second research question considers the level of ASX Recommendations that are adopted in each year, it will be informative to identify factors associated with changes in governance over time Hence the third research question asks:
RQ3 What firm characteristics explain changes in the governance environment of smaller
firms over time?
As discussed in section 1.2, while there is a considerable body of literature on corporate governance, there is comparatively little empirical evidence related to the efficacy of corporate governance in smaller firms To addresses the deficiency in the literature, the fourth research question asks:
RQ4 How effective are the corporate governance attributes of smaller listed firms?
1.5 Theoretical framework
In addressing the research questions, this study draws on agency theory and prior literature to develop a research framework The separation of ownership and control gives rise to the agency problem In the framework, agency costs are mitigated through three principal means: external monitoring, transparency in disclosure, and an effective internal corporate environment As a formal part of the framework, an effective internal governance

environment is expected to contribute to the reduction of agency costs This is consistent with the rationale for the introduction of the recommendations, as the ASXCGC describes the recommendations as providing a reference point for structures to minimise problems and optimise performance and accountability (2003, p 3)
Within this framework, six testable research hypotheses are developed to address the research questions The first two hypotheses explore the extent and nature of corporate governance in smaller listed Australian firms, and investigate the factors associated with differences in adoption rates of the recommendations The four remaining hypotheses address the effectiveness of corporate governance by assessing its associations with four measurable outcomes drawn from the literature The four outcomes are firm performance (Cremers and Nair, 2005), disclosure (Beekes and Brown, 2006), receipt of an ASX query (Neagle and Tsykin, 2001) and the probability of receiving a modified audit opinion (Farinha and Viana, 2009)
1.6 Research design
This thesis examines the corporate governance practices and outcomes of a sample of 298 smaller firms for the years 2002 to 2006 A five-year period is chosen for several reasons First, the ASX Recommendations became effective for financial years ending in 2004 and a three-year period following the commencement of the recommendations is selected to allow changes in governance structures to be observed This is consistent with the guidance from the ASXCGC, who counselled against rapid and wholesale changes (2003, p 5) Second, to facilitate analysis of the changes engendered by the introduction of the recommendations, data is also collected for the two years prior to the commencement of the new code While a full comparison of the pre- and post-introduction periods is not possible, a limited comparison can be made using a number of governance items that can be assessed in both phases, aiding the analysis of changes induced by the introduction of the recommendations Assessing the nature and extent of corporate governance in smaller firms requires extensive manual collection of data from company annual reports, which has also constrained the analysis to a five-year period
The principal aim of this thesis is to explore the corporate governance environment of smaller listed Australian firms Achieving this aim requires the largest companies to be omitted and accordingly, firms in the top 300 by market capitalisation are excluded In addition, Australia
Trang 3210
has a large number of very small listed companies, and these firms are also excluded to avoid
dissimilar to smaller or mid-tier firms4 Accordingly, this thesis defines smaller firms as mid-tier firms outside of the top 300 and with a 2006 year-end market capitalisation greater than
$30M
The research methods used to examine the nature and extent of governance in smaller companies include both univariate and multivariate procedures Governance indices are constructed to assess the factors associated with differences in the rates of adoption of the ASX Recommendations The effectiveness of corporate governance is investigated by utilising three research models based on individual internal corporate governance mechanisms derived from the literature, an index derived from selected individual internal corporate governance mechanisms, and an index constructed from conformance with the ASX recommendations The model using the index derived from the ASX recommendations uses a subset of the data for the years 2004 to 2006 Regression analysis methods are used to assess the effectiveness
of governance through its association with four measurable outcomes drawn from the literature
1.7 Summary of major findings
The analysis of the nature and extent of the adoption of the ASX recommendations reveals that the overall mean level of adoption of the ASX recommendations rose from 66 per cent in
2004 to 74 per cent in 2006 However, there is substantial variance in the rates of adoption of individual recommendations: in 2004 only 26 per cent of firms disclosed the existence of a nomination committee, while 91 per cent provided disclosure of remuneration policies Structural recommendations, related to board characteristics and committee formation, have consistently lower rates of adoption than recommendations that refer to policies and procedures related to behaviour and disclosure Regression analysis indicates that larger firms, more profitable firms, firms with larger boards, firms using BIG 4 audit firms, and firms with greater ownership dispersion have internal governance environments that are more reflective of the ASX recommendations

In 2006 there were approximately 900 companies with a market capitalisation below $30M listed on the ASX

The results of models using governance indices to test the effectiveness of corporate governance find consistent evidence of a positive association between accounting-based performance and internal corporate governance attributes While indices of structural
associations between better governance and market performance, market-sensitive disclosure, or ASX queries Conformance with disclosure-based recommendations is associated with a lower probability of receiving a modified audit opinion
-Results on the effectiveness of individual corporate governance attributes provide a number of key insights First, the results highlight the importance of an independent board chair for smaller companies In contrast, there is little evidence that a majority independent board is associated with superior outcomes Together, these results indicate that board independence and chair independence may be substitutes; in the presence of an independent chair, a majority independent board may be an unnecessary and costly investment for smaller companies Second, analysis of specific audit committee characteristics demonstrates that the independence of the committee chair and accounting-based expertise of the committee members are the most important characteristics for smaller firm audit committees While majority independent committees are viewed as desirable, there was little evidence to support this recommendation
The overall results highlight the importance of an independent board chair, an independent audit committee chair, and the accounting-based expertise of both the board and audit committee members In contrast, there was no evidence that greater board independence or the existence of remuneration or nomination committees was associated with enhanced performance Together, these results provide support for the principles-based approach to corporate governance of the ASX Rather than being constricted by a mandatory rules-based system, the ASX approach enhances the ability of all listed firms to achieve an optimal corporate governance environment
1.8 Contribution of the study
The findings of this study contribute to the scarce corporate governance literature related to smaller listed companies, and more specifically to the literature related to the corporate governance of smaller Australian firms Despite the large number of smaller listed firms in the Australian market, previous research has not detailed the extent to which these firms have
Trang 3412
implemented the ASX recommendations This study provides an extensive assessment of the corporate governance practices of a sample of these firms over a five-year period The study demonstrates that, despite the increasing level of conformance with the recommendations, many smaller companies are utilising the flexibility inherent in the governance code by only adopting recommendations that are appropriate to their needs and providing an explanation for non-adoption of other recommendations
A number of findings may also have implications for future policy decisions Achieving a majority independent board is a potentially expensive exercise for many smaller companies, yet there was little evidence that a majority independent board conveyed extensive benefits
On the contrary, majority independent boards were associated with a higher probability of receipt of a modified audit opinion These findings and the positive findings regarding the independence of the board chair, suggest that in smaller companies where resources are limited, an independent board chair is more efficacious than a majority independent board, consistent with the existence of a substitution effect
The audit committee is a key corporate governance mechanism, and its importance is reflected
in the three recommendations related to committee formation, composition and charter The results of this study indicate that two committee characteristics, the independence of the chair, and greater accounting-based expertise on the committee, are associated with superior outcomes In the presence of an independent chair and relevant expertise, the independence
of the committee has little discernible effect on firm outcomes Future reviews of the corporate governance recommendations may consider providing improved guidance to smaller companies that are unable to form audit committees that are fully compliant with the recommendations Moreover, policy-makers may consider giving greater emphasis to the technical skills of the committee members, as at present this aspect merely forms part of the accompanying guidance and is not part of the recommendations
1.9 Organisation of the thesis
The remainder of this thesis is structured as follows Chapter Two explores the development
of corporate governance codes in Australia, and then reviews the codes of major international and regional markets, before comparing how the different markets cater for the needs of smaller firms Using agency theory as its basis, Chapter Three considers the relevance of corporate governance, and reviews the findings of prior literature while considering how the
Trang 3513
results apply to smaller companies In Chapter Four, a theoretical framework is proposed and
a series of testable research hypotheses are developed Chapter Five describes the research design, including the study period, sample selection, data collection, research models, and the definition of the variables Chapter Six presents the results of tests of Hypotheses 1 and 2 that consider the nature of the governance recommendations adopted by the sample firms, and the factors that explain the variation in the internal governance environment of smaller firms The effectiveness of corporate governance, tested by Hypotheses 3 to 6, is the focus of Chapter Seven which presents the results of tests of the association between governance attributes and firm performance and disclosure, and two adverse outcomes, receipt of an ASX query and the probability of receipt of a modified audit opinion Chapter Eight concludes the thesis with a discussion and summary of the findings, major contributions, limitations and potential implications for policy

Chapter Two Institutional setting
2.1 Introduction
Listed companies are characterised by the divergent interests of stakeholders Good corporate governance aims to balance and protect the interests of various stakeholders by ensuring that appropriate mechanisms to align these divergent interests are in place and to ensure adequate monitoring of management The disclosure of corporate governance practices enables market participants to assess the adequacy of such practices and mechanisms and where necessary, agitate for improvement (Ramsay and Hoad, 1997) Consistent with this and in the context of the Australian market, firms are able to adopt governance practices and mechanisms that best suit their size, structure or complexity The disclosure of such practices enables investors to make their own assessment of the risks associated with each firm
This chapter discusses the development of governance codes in Australia and reviews subsequent reforms that have led to the present model for governance and its disclosure A review of the various approaches to corporate governance across major global and regional markets is undertaken to identify similarities and differences in the operation of governance codes The chapter concludes with a comparison of how the various governance codes and recommendations apply to companies of different size
2.2 Development of corporate governance principles and disclosure in Australia
This section traces the introduction and evolution of corporate governance codes in Australia and the changes in the ASX listing rules pertaining to disclosure of governance in company annual reports There are three important dates in the evolution of corporate governance reporting in Australia: 1991, 1996, and 2004 The dates and changes are encapsulated in a flowchart in Figure 2.1
Trang 38of investor and public confidence The guide set out two objectives: to provide guidance for directors, officers and professional advisors as to what
is acceptable conduct and practice; and to spread and reinforce high standards of corporate conduct (Bosch, 1991, p 1)
The recommendations set out in the guide were voluntary The extent to which they were followed is open to speculation; not only was any form of compliance voluntary but so too was the disclosure of governance practices However, the guide proposed that the annual reports
of all public companies should include a statement that the company supports and has adhered to the principles espoused in the guide, and that any departures from the principles should be noted and the reason for the departures given Despite the widespread acceptance
of the guide and the input of business groups (including Business Council of Australia and The Australian Institute of Company Directors) and two professional accounting bodies, Australian Society of Certified Practising Accountants (now CPA Australia) and the Institute of Chartered Accountants in Australia (ICAA), the recommendations for disclosure do not appear to have won common acceptance Of the 299 annual reports in the Connect 4 database for the 1994 financial year, Collett and Hrasky (2005) identified only 30 companies that made voluntary corporate governance disclosures Furthermore, their findings indicated that the disclosures may have been motivated by a desire to subsequently raise debt or equity capital

In September 1994 the ASX released a discussion paper, canvassing options for the corporate governance requirements that would later be released as Listing Rule 3C(3)(j), requiring mandatory disclosure of governance practices from 1996 The new rule required companies to set out in their annual reports a statement of the main corporate governance practices that the company had in place during the reporting period Although the new rule was only to apply from 1996, the ASX had earlier indicated that compliance would be encouraged in the intervening period (Carson, 1996) Examining the voluntary disclosures in the 1995 reporting period, Carson reports that only two per cent of companies were fully compliant, only 11 per cent disclosed more than half of the required items, and 33 per cent did not comply with any aspect of the new rule other than that already required by existing rules Her findings also indicate that larger companies and companies with listings on overseas stock exchanges were more likely to voluntarily disclose more information The findings of Carson, and Collett and Hrasky (2005), indicate reluctance on the part of Australian listed companies to voluntarily disclose details of their corporate governance policies and procedures in the mid-199
2.2.2 Introduction of Listing Rule 3C(3)(j) (1996-2004)
The Australian Securities Exchange (ASX) introduced Listing Rule 3C(3)(j), to apply from reporting periods on or after 30 June 1996, requiring listed companies to include a statement
of their main corporate governance practices in place during the year To assist companies, the ASX published as an appendix to the rule an indicative list of nine governance matters for companies to take into account when completing the governance statement for inclusion in the annual report The rule was based on a similar rule of the London Stock Exchange that originated in the Cadbury report (Collett and Hrasky, 2005) and did not mandate any governance practices but merely required disclosure of the main practices that the company had in place during the reporting period
The effectiveness of Listing Rule 3C(3)(j) was subject to assessment soon after it took effect The ASX issued a media release in March 1997 which indicated that every one of the top 150 listed companies had complied with the new rule In contrast, the Australian Investment

with t box-ticking , or compliance with the spirit of the law can
be achieved by providing high quality disclosures
A shortcoming of the AIMA and ASX studies is that the sample companies were from the largest companies by market capitalisation and not representative of the entire market A more comprehensive assessment of compliance with the new listing rule was undertaken by Ramsay and Hoad (1997) Using a sample of 268 annual reports drawn from large, medium and small listed companies, they found substantial shortcomings in the governance disclosures Amongst the findings were that 25 per cent of companies did not discuss the criteria for board membership, 23 per cent did not discuss management remuneration, and 65 per cent did not discuss procedures for reviewing the performance of the management or directors The extent and quality of governance disclosure was typically better for large companies than for small and medium-sized firms Given that the AIMA study found
observe shortcomings in the disclosures of medium and smaller firms
2.2.3 Principles of Good Corporate Governance and Best Practice Recommendations
Following a spate of corporate collapses in 2001, both in Australia and internationally, there were renewed calls for improved corporate governance and increased regulation In response the ASX formed the ASX Corporate Governance Council (ASXCGC) comprising members from
21 business and professional organisations6 Their unanimous goal was to:
-wide, supportable and supported framework for corporate governance which could provide a practical guide for listed companies, their investors, the wider market and the Australian community (ASX, 2003, Foreword)
Although improving the stewardship of public companies was a major motivation for requiring enhanced corporate governance, it is not the sole rationale Other motivations for demonstrating good corporate governance, both on an
