Rate regulated activities: a problemática do relato financeiro e da sua auditoria: o caso da navegação aérea no contexto europeu

A navegação aérea, enquanto atividade regulada, está sujeita a legislação específica, dependendo o seu exercício de autorização própria atribuída por uma entidade supervisora, que também verifica as tarifas a aplicar. O regulamento (CE) N.º 550/2004 identifica os requisitos comuns para a prestação de serviços de navegação aérea na Europa, dando particular importância à transparência do relato financeiro ao exigir a sua elaboração segundo as normas internacionais de contabilidade e a verificação por uma auditoria independente. Adicionalmente, o Regulamento (EU) N.º 1191/2010, que alterou o Regulamento (CE) N.º 1794/2006, estabelece o regime comum de tarifação de tais serviços, nomeadamente a recuperabilidade de desvios relativos ao volume de tráfego e aos gastos controláveis e não controláveis. Ao nível do enquadramento contabilístico, as atividades reguladas não têm uma norma específica. Existem dois projetos do IASB – um de 2009, que foi suspenso, e um de 2013, relativo à implementação de uma norma transitória que incentive a adoção das normas internacionais por entidades que exerçam atividades reguladas. Existe, ainda, uma norma do FASB não aplicável no espaço europeu. Os R&C de várias entidades evidenciam a existência de diferentes referenciais contabilísticos e que a generalidade dos relatórios de auditoria não tem reservas ou ênfases. Enquanto algumas entidades apenas divulgam os montantes dos desvios, outras entidades consideram que tais montantes se qualificam, reconhecendo-os. Tal facto decorre da inexistência de uma norma internacional que põe em causa a comparabilidade da informação financeira e dificulta o julgamento do auditor quanto à adequação ou não dos procedimentos adotados pela entidade.

Sustainability reporting and financial reporting: the relevance of an integrated reporting approach

In the business world, there are issues such as globalisation, environmental awareness, and the rising expectations of public opinion which have a specific role in what is required from companies as providers of information to the market. This chapter refers to the current state of corporate reporting (financial reporting and sustainability reporting) and demonstrates the need for evolution to a more integrated method of reporting which meets the stakeholders’ needs. This research offers a reflection on how this development can be achieved, which notes the ongoing efforts by international organisations in implementing the diffusion and adoption, as well as looking at the characteristics which are needed for this type of reporting. It also makes the link between an actual case of a company that is one of the world references in sustainable development and integrated reporting. Whether or not the integrated reporting is the natural evolution of the history of financial and sustainability reporting, it still cannot yet claim to be infallible. However, it may definitely be concluded that a new approach is necessary to meet the needs which are continuously developing for a network of stakeholders.

Stressful working conditions and poor self-rated health among financial services employees

OBJECTIVE: To assess the association between exposure to adverse psychosocial working conditions and poor self-rated health among bank employees. METHODS: A cross-sectional study including a sample of 2,054 employees of a government bank was conducted in 2008. Self-rated health was assessed by a single question: "In general, would you say your health is (...)." Exposure to adverse psychosocial working conditions was evaluated by the effort-reward imbalance model and the demand-control model. Information on other independent variables was obtained through a self-administered semi-structured questionnaire. A multiple logistic regression analysis was performed and odds ratio calculated to assess independent associations between adverse psychosocial working conditions and poor self-rated health. RESULTS: The overall prevalence of poor self-rated health was 9%, with no significant gender difference. Exposure to high demand and low control environment at work was associated with poor self-rated health. Employees with high effort-reward imbalance and overcommitment also reported poor self-rated health, with a dose-response relationship. Social support at work was inversely related to poor self-rated health, with a dose-response relationship. CONCLUSIONS: Exposure to adverse psychosocial work factors assessed based on the effort-reward imbalance model and the demand-control model is independently associated with poor self-rated health among the workers studied.

Power law analysis of financial index dynamics

Power law PL and fractional calculus are two faces of phenomena with long memory behavior. This paper applies PL description to analyze different periods of the business cycle. With such purpose the evolution of ten important stock market indices DAX, Dow Jones, NASDAQ, Nikkei, NYSE, S&P500, SSEC, HSI, TWII, and BSE over time is studied. An evolutionary algorithm is used for the fitting of the PL parameters. It is observed that the PL curve fitting constitutes a good tool for revealing the signal main characteristics leading to the emergence of the global financial dynamic evolution.

Relativistic time effects in financial dynamics

Financial time series have a complex dynamic nature. Many techniques were adopted having in mind standard paradigms of time flow. This paper explores an alternative route involving relativistic effects. It is observed that the measuring perspective influences the results and that we can have different time textures.

Complex dynamics of financial indices

This paper presents a novel method for the analysis of nonlinear financial and economic systems. The modeling approach integrates the classical concepts of state space representation and time series regression. The analytical and numerical scheme leads to a parameter space representation that constitutes a valid alternative to represent the dynamical behavior. The results reveal that business cycles can be clearly revealed, while the noise effects common in financial indices can elegantly be filtered out of the results.
