overnment r egulation o f business organizations is based on the assumption that the government’s objective is to maximize social welfare Such activities are justified in order to overcome the apparent failure of free markets to deal with problems of consumer detriment arising externally, economies of scale, imperfect i nformation, a nd i nadequate ma rkets f or r isky o utcomes, a nd a lso because of the problem of the maldistribution of wealth However, an alternative “public choice” view of the government regulation of business organizations questions the assumption that business organizations regulation is inherently different from other markets It suggests instead that politicians and regulators seek to maximize and secure their own welfare through imposing taxes and conferring subsidies Under this view, the © 2010 by Taylor and Francis Group, LLC Determination of U.K Pension Fund Accounting Rules ◾ 391 government regulation is only justified to the extent that it reduces or eliminates costs associated with observed market failure and the delivery of these services This view leads to claims that the financial regulation incurs costs that are primarily borne by consumers and taxpayers, which probably exceed the benefits they receive and that regulation favors the politically powerful In common with other types of not-for-profit organizations, pension funds hold monies in trust that are relevant to various constituencies, whose values and interests may conflict with one another (Hofstede, 1981) An important issue in this political process is the role of pressure groups in exerting control over t he flow o f financial i nformation about t he c urrent pension f und management’s performance in order to secure the accountability of a pension fund t o it

accounting rule-making bodies can translate their expenditures into political influence over government-sanctioned, and thus legally enforceable, accounting regulation It applies a m odel of competition a mong multiple pressure groups originally developed by Becker (1983) to analyze the sources of political pressures A primary source of these pressures is the economic and political accountability processes by which these groups attempt to develop competing accounting standards in an attempt to secure their political credibility These standards in turn codified different interpretations over the nature and ownership of the pension fund surplus among the various pressure groups.* We predict that auditors, pension management, and accounting rule-making bodies all had incentives to influence both the adoption and the retention of the U.K pension fund disclosure regulations Consistent with a private interest perspective, t he audit profession a nd t he pension ma

17.2.1 Prior Research Two apparently contradictory research paradigms have sought to explain the political processes underlying the development of accounting regulation These i n t urn m otivated em pirical r esearchers t o de velop a nd te st competing explanations for the determination of accounting rules Each of these paradigms assumes that the process of accounting standard setting is subject to a single, dominating pressure group For ex ample, Watts a nd Z immerman (1978) (WZ h ereafter) assume that corporate managers are self-interested and that their own lobbying behavior i s primarily motivated by sel f-interest Their st udy st imulated a large body o f literature t hat examined t he factors a ffecting t he choice of accounting methods in corporations (e.g., Hagerman and Zmijewski, 1979; Bowen et al., 1981), municipalities (Zimmerman, 1977), and public sector pension funds (Stone et al., 1987) Accounting is viewed by WZ as a product of r ational dec ision ma kers a nd a s a m echanism for controlling potential conflicts of interest between principals (e.g., pension plan participants) a nd t heir agents (i.e., pension scheme ma nagers) WZ r ely on an underlying economic theory of regulation, which assumes that politicians a nd r egulators a ttempt t o ma ximize t heir o wn sel f-interest This assumption provides both a theoretical basis for analyzing corporate

(PAT) researchers to adopt an agency theory of the firm to develop theories of accounting practice (WZ, 1986) The economic theory of regulation upon which WZ based their analysis had been developed by an earlier generation of economists (Stigler, 1971; Pelzman, 19 76) This theory depicted corporate managers as essentially driving r egulatory p rocesses; t he po tential i nfluence o f o ther p

seeking to secure political influence over attempts to regulate their accounting practices However, WZ (1986, p 112) acknowledge that this assumption is limited and that there is a need for further theory to model explicitly competition among interest groups for political influence An a lternative soc ial sc ience a pproach t o u nderstanding t he po litics surrounding acco unting r ule-making p

This literature employs case studies to explore the regulatory space occupied by pressure groups in influencing the standard setting process (Hancher and Moran, 1980; Young, 1994) It emphasizes the role of public policy in “correcting” market failures This public interest perspective recognizes the complexity of the formation of agendas and of standard setting, particularly by examining the situation of the standard setting body and its social and historical contexts (Burchell et al., 1980; Hopwood, 1983) Viewing accounting standard setting as a political process, with its sensitivity to environmental pressures and the pursuit of legitimacy affords important insights into the behavior of such pressure groups (Fogarty, 1998) This characterization of accounting regulation a lso places st andard se tting ac tivities w ithin t he broader political arena (Hope and Gray, 1982; Cooper and Sherer, 1984; Hussein and Ketz, 1991; Fogarty et al., 1994) The setting of agendas for standard

accounting standard setting process can be reconciled by recognizing that each perspective assumes that a single powerful pressure group effectively determines the political processes that underlie the development of accounting r ules A n a lternative, more sophisticated perspective instead views legally enforceable accounting rules as being ultimately determined © 2010 by Taylor and Francis

interests of a wide and diff use range of pressure groups analyzed by Becker (1983); for example, pensioners, corporate sponsors, corporate accounting rulemaking bodies, and employees.† Analyzing

that regulation (e.g., accounting standard setting) activities correct market failures with the alternative view that they favor the politically powerful: both are produced by the competition for political influence ‡ Becker’s (1983) model has been applied to model political game plays between various pressure groups that seek to exert political influence over the outcome of congressional

the positions of the two pressure groups on U.K pension plan financial reporting, which are briefly explained in more detail in the rest of this section The ownership of pension f unds i n t he United K ingdom is governed by the unique agency relationships between trustees and delegated professional ma nagement t hat a re r esponsible f or e ssential ad ministration and investment functions Consistent with prior research, it is assumed that sponsoring firm shareholders own both pension assets and liabilities (e.g., Landsman, 1986), and hence their interests are also assumed to be compatible with those of pension management.* * The role of t he employer sponsor i n U.K pension f und accounting standards is somewhat ambiguous, since firm cash flows are not directly affected by pension fund financial reporting For DBPPs, employer sponsors face incentives that are both compatible (i.e., provide retirement income insurance) and incompatible (i.e., confl ict over the ownership of surplus/ deficit) with that of their employees © 2010 by Taylor and Francis Group, LLC Determination of U.K Pension Fund Accounting Rules ◾ 397 These relationships are economically significant since pension funds in aggregate hold more equities than individual investors in many international financial markets (Davis, 1995) and involve a number of participants For example, pension fund trustees pay managerial expenses and fees for the delegated administration and investment services provided to pension funds by pension professionals, such a s ac tuaries a nd auditors (Klumpes and McCrae, 1999) Another important interested party is pension management whose main concern is managing the vast assets under their control and wh om a re a ssumed t o be sel f-interested a gents wh ose a im i s va luemaximizing their fee income derived from operating the pension fund This institutional setting bears on the analysis of the determination of pension f und financial reporting rules because auditors, pension management, and PRAG may significantly influence a del egated pension f und manager’s attitude toward the political visibility in adopting or retaining certain pension fund financial d isclosures P ension ma nagement first d eveloped i ndustryrecommended guidelines (IRG) for annual reporting to participants in 1986 (Klumpes, 1994b) Unlike the SORP subsequently developed by PRAG, IRG constituted “best practice” reporting standards and were not enforceable However, a fter t he Ma xwell pens ion sch eme f raud wa s d iscovered in 991, t he adeq uacy o f t he ex isting, sel f-regulated r eporting a rrangements affecting U.K pension funds was criticized in public enquiries into the financial accountability of pension fund managers to participants (Klumpes, 1994a) These i nquiries p roposed t hat f ully a udited financial statements be included in annual participant reports (Klumpes, 1993) In the United Kingdom, the original SORP (pension scheme accounts), issued in 1986, asserted that pension fund assets and liabilities are subjective actuarial estimates that were beyond the scope of the scheme’s accounts Subsequently, PRAG sought to update the SORP to improve the usefulness and intelligibility of the annual report by incorporating robust, externally credible market valuations of pension fund assets (but not their liabilities) An exposure draft (ED) of the revised SORP was published by PRAG in September 1995 Following an invitation for further comment on a range of issues, the final version of the revised SORP was published in September 1996 The revised SORP was subsequently mandated by U.K government legislation u nder t he Pension Di sclosure Reg ulations of 1997 W hile t he SORP was further amended to include reference to ongoing developments in the U.K GAAP during 2002, long-term pension liabilities were still not incorporated into t he financial st atements o f pens ion p lans; de spite t he U.K GAAP requiring this for employer sponsors’ financial statements © 2010 by Taylor and Francis Group, LLC 398 ◾ Pension Fund Risk Management: Financial and Actuarial Modeling U.K pensions legislation now requires that the board of trustees responsible for managing pension funds comprises equal representation by both their employee (to whom auditors, who must comply with accounting standards, are ultimately accountable) and employer pressure groups (to whom pension management, who may seek to voluntarily comply with IRG, are accountable) These institutional features are important for a number of reasons First, the form a nd t he content of financial statements can have a ma terial a nd noncosmetic effect on how these interests are represented, that is, how the pension fund net surplus or deficit is measured Second, differing views can also critically affect the employer sponsors’ funding and asset allocation policy Thir d, there was a o ne-time, nonreversible voluntary switch available to adopt t he competing accounting standards during an extended transitional period.* 17.2.3 Theoretical Antecedents The a nalytical f ramework em ployed i n t his cha pter r elies o n B ecker’s (1983) t heory o f

iffers subst antially f rom t hat o f p rior researchers Furthermore, this view ignores the extrinsic or intrinsic benefits of regulation a nd t he endogeneity of a r ange of soc ially i nfluenced costs and benefits that can significantly vary among groups Consistent with the U.K government’s notion of a stakeholder society, this chapter assumes instead that relevant costs and benefits are not objectively determined but are subject to influence by multiple pressure groups that compete for taxes and subsidies that arise from any politically determined regulatory system Thus, understanding the nature and dynamics of this political equilibrium is necessary in order to approximate the magnitude and the incidence of a wider range of socially influenced costs and benefits associated with any regulatory change This insight is based on the economic theory of regulation (Becker, 1983), which recognizes that any regulatory change is subject to a po litical process in which some groups (e.g., intermediaries) receive benefits that are effectively paid for by costs imposed on other groups (e.g., investors) Politicians and rule-makers are * Standards for pension fund financial reporting were subsequently mandated by government regulation (Pension Act, 1995) pension laws © 2010 by Taylor and Francis Group, LLC 404 ◾ Pension Fund Risk Management: Financial and Actuarial

pension funds (DISCLi) Finally, political visibility proxied by fund size must be controlled for in disclosure policies (SIZEi) Combining t hese factors into equation form, the following generalized political influence function is hypothesized: POLICYi = f ii (SIZEi , FEEi , COSTi , PASi , DISCLi ) (17.7) In summary, Equation 17.7 predicts that direct sources of pressure in the form of pressure by PRAG over accounting standards for reporting (via DISCL and PAS), together with fees paid directly to auditors (Equation 17.5), as well as costs incurred by delegated pension management in securing this accountability relationship (Equation 17.6), are credible sources of political pressure functions produced by special interest pressure groups These pressure functions in turn then combine with both pension funds’ accounting policy choices and the disclosure of financial information to members to determine a regulatory agency’s discretion over the form and the co ntent o f g

statement of changes in financial position, an investment per formance report, a nd a su mmary of t he actuarial report In addition to disclosure and accounting practices, another predicted economic source of pressure for costs incurred by pension plans is MATRISK, which is a proxy for the pension plan’s financial condition The older the age profile of pension plan members, the greater is the cash flow needed to fund benefits, which must be generated from investments It is measured as the flow funding relationship of total contributions received, plus gross investment returns, less total benefit pa yments U nlike t he t raditional stock funding ratio, the flow funding ratio is not subject to actuarial discretion over assumption rates used to discount pension liabilities During the study period, there was considerable political pressure placed on U.K pension f unds to maintain a n et surplus by using conservative actuarial assumptions for the estimation of pension liabilities

limitation mentioned earlier because of the lack of recognized alternatives in this study, LNSIZE is a proxy for political visibility It is measured by the net market value of assets of a pension fund For statistical testing purposes (see discussion in the following text), these were converted to natural log scale Finally, a proxy is needed to measure political influence However, prior research has not successfully identified a measurable proxy for this variable I n t his chapter, a d isclosure i ndex POLICY is u sed to measure t he extent of political influence This variable is comprised of 144
