Audit Committees Oversight of Information Technology Risk

This exploratory study examines the role of the audit committee in overseeing information technology (IT) risk. We address the degree of audit committee oversight of specific IT risks, as well as factors associated with variations in audit committee IT oversight. Based on responses from 39 audit committee members, we found (1) little audit committee emphasis on oversight of IT risks, (2) audit committees involved with IT oversight focus on more traditional risks (e.g., monitoring), while very little attention is devoted to IT acquisition and implementation, and (3) the amount of IT oversight is positively associated with the responding members auditing experience and prior familiarity with the COBIT model for assessing IT risks. Audit committee independence, diligence, and expertise, company size, and industry were not significantly associated with IT oversight

Audit Committee Effectiveness: A Synthesis of the Empirical Audit Committee Literature

The article describes the factors that contribute to audit committee effectiveness. An effective audit committee has qualified members with the authority and resources to protect stakeholder interests by ensuring reliable financial reporting, internal controls, and risk management through its diligent oversight efforts. The determinants of audit committee effectiveness includes the audit committee composition, authority, resources and diligence. The major U.S. stock exchanges require that audit committees be composed of at least three independent, financially literate directors. Team issues also are relevant when considering audit committee composition. The audit committee derives its authority from the full board of directors, federal law and exchange listing requirements. Authority is viewed as a function of the audit committees responsibilities and influence. Audit committee authority also depends on the audit committees relationships with management, external and internal auditors and the board as a whole. The resource component of audit committee effectiveness highlights that effective oversight is contingent upon the audit committee having adequate resources to do its job. Diligence is the process factor that is needed to achieve audit committee effectiveness

Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV

The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8  TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum
