La conclusión fundamental es que las variables rentabilidad económica, valor contable y ratio PER son consideradas estadísticamente significativas en la explicación del precio de mercado de las acciones del Ibex 35.

Evidência empírica dos factores explicativos dos dividendos distribuídos pelas empresas cotadas na EURONEXT Lisboa

Companies’ decision to pay dividends to its shareholders is a topic that has received increasing attention in business finance. This paper provides an additional contribution to the development of this topic focusing on the analysis of the determinants of dividend policy by issuing companies in the Portuguese capital market. For this purpose, we use a set of financial and economic information specific to each firm to explain its dividend per share. The sample used in the empirical study contains 54 firms and it refers to the 2005-2009 period. Results suggest that net income, dividends per share paid in the previous financial year and return on assets all present a positive and statistically significant effect on dividends per share paid in a given financial year. Moreover, results show that Lintner’s (1956) model appears to be valid in explaining dividend policy by issuing companies in Euronext Lisbon.

Factores determinantes do nível de divulgação sobre instrumentos derivados de acordo com as recomendações do Basel Committee on Banking Supervision e da Organisation of Securities Commissions - evidência empírica no sector bancário português

Este estudo analisa o nível de divulgação sobre instrumentos derivados e seus factores determinantes nas entidades bancárias portuguesas. Para o efeito, foi utilizado um índice de divulgação, baseado nas recomendações emitidas pelo Basel Committee on Banking Supervision e pela Organisation of Securities Commissions, e analisados os Relatórios & Contas anuais, individuais, relativos a 2009. Conclui-se que o número de empresas que apresenta informação sobre a utilização de instrumentos derivados é bastante elevado, mas o valor médio de divulgação apresentado é bastante reduzido. Identificam-se, como factores determinantes do nível de divulgação, o tamanho da empresa, a qualidade do auditor externo e o facto de a empresa ter procedido a um aumento de capital durante o exercício económico em análise.

Grau de cumprimento com as recomendações do Basel Committee on Banking Supervision e da Organisation of Securities Commissions, sobre divulgação de informação relacionada com instrumentos derivados - evidência empírica no sector bancário português

This study analyzes the level of disclosure on derivatives, in accordance with the recommendations issued by the Basel Committee on Banking Supervision and the Organization of Securities Commission, by Portuguese banks. We have analyzed individual annual reports related to 2009, using a disclosure index based on those recommendations. We concluded that the number of companies that provides information about derivative instruments is quite high, but the average value of disclosure is very low. The information disclosed more frequently is that related to general aspects, followed by information related to accounting and valuation methods.

Estudo do grau de cumprimento com as recomendações do Basel Committee on Banking Supervision e da Organisation of Securities Commissions, sobre divulgação de informação relacionada com instrumentos derivados, pelas entidades portuguesas pertencentes ao sector bancário

Este estudo analisa o nível de divulgação sobre instrumentos derivados, de acordo com as recomendações emitidas pelo Basel Committee on Banking Supervision e pela Organisation of Securities Commissions, pelas entidades bancárias portuguesas. Para o efeito, foi utilizado um índice de divulgação e analisados os Relatórios & Contas anuais, individuais, relativos a 2009. Conclui-se que o número de empresas que apresenta informação sobre a utilização de instrumentos derivados é bastante elevado, mas o valor médio de divulgação apresentado é bastante reduzido. A informação mais divulgada é a relativa a informações gerais, seguida da informação relacionada com contabilidade e métodos de avaliação.

Factores explicativos da divulgação de informação sobre instrumentos derivados: evidência empírica no mercado de capitais português, em 2008

This study analyses the determinants of the derivative instruments disclosure level by Portuguese listed companies. It is built a disclosure index to measure the disclosure level using the Consolidated Annual Reports for 2008. The hypotheses have been tested through a linear regression model using the disclosure index as the dependent variable and companies’ characteristics as independent variables. Multivariate results suggest that firm size, quality of the external auditor, belonging to PSI 20, the market to book value ratio and the percentage of capital hold by the board of directors are associated with the disclosure level.

Bioactive albumin functionalized polylactic acid membranes for improved biocompatibility

Biocompatibility is a major challenge for successful application of many biomaterials. In this study the ability to coat chemically and enzymatically activated poly(L-lactic acid) (PLA) membranes with heat denatured human serum albumin to improve biocompatibility was investigated. PLA membranes hydrolyzed with NaOH or cutinase and then treated with 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, hydrochloride (EDAC) as a heterobifunctional cross-linker promoted the coupling single bondCOOH groups on PLA membranes and single bondNH2 groups of heat denatured human serum albumin. This resulted in increased hydrophilicity (lowest water contact angles of 43° and 35°) and highest antioxidant activity (quenching of 79 μM and 115 μM tetramethylazobisquinone (TMAMQ) for NaOH and cutinase pretreated membranes, respectively). FTIR analysis of modified PLA membranes showed new peaks attributed to human serum albumin (amide bond, NH2 and side chain stretching) appearing within 3600–3000 cm−1 and 1700–1500 cm−1 (Fig. 3). MTT studies also showed that osteoblasts-like and MC-3T3-E1 cells viability increased 2.4 times as compared to untreated PLA membranes. The study therefore shows that this strategy of modifying the surfaces of PLA polymers could significantly improve biocompatibility.

Stability, sustainability and viability of the Portuguese Football Federation

Purpose: to evaluate and study the viability, stability and the ability of the Portuguese Football Federation (PFF) to generate sustained profits. Methodology: Data were collected based on the Audit Reports of the institution during 2012-2014 and a financial and economic analysis was performed in order to establish some indicators of solvability, profitability and financial balance. Findings: It exists a lack of consistency in managing the profits obtained. We can also suggest that should be given a greater interest to the management of their own intangible assets, as brand management, for example. Practical implications: By making known to leaders and managers of this type of institutions that exists a link between participation in international championships and increase of their profitability may encourage them to better managing these cash inputs in order to decrease the dependence of Governmental financing. We also found that the management of their own intangible assets, as brand management, for example, could probably add more positive financial results.

La creación de valor del integrated reporting

El lanzamiento por parte del IIRC del International Integrated Reporting Framework en 2013, supone un nuevo Marco Internacional para la elaboración de informes financieros y puede marcar un cambio importante en la evolución de la información empresarial. Se trata de conseguir una información confiable, clara y comparable, dirigida a una amplia gama de partes interesadas. Además de información económica-financiera clásica, el Integrated Reporting (IR) abarca cuestiones sobre la estrategia de la organización, la gobernanza, los resultados y las perspectivas, elementos que conducen a la creación de valor a corto, medio y largo plazo. Nos planteamos conocer si la información integrada aumenta la creación de valor para las empresas. Para ello, se analiza la evolución de la Q de Tobin de las empresas españolas que desde 2011 están en el programa piloto sobre información integrada del IIRC en relación con el resto de empresas pertenecientes al IBEX 35. Los resultados muestran que el comportamiento de estas empresas es más positivo que la media del sector aunque los datos están muy influenciados por la situación de crisis.
