The paper aims to investigate the influence of corporate governance of the banks that operate in the cooperative credit system on performance and quality of loans, over the years 2010-2011-2012. In order to achieve this aim, the following research hypotheses have been formulated： There is a statistically significant relationship between the size and the structure of the board and banks Performance operating in the cooperative credit system; there is a statistically significant relationship between the size and structure of the board and the credit quality of banks operating in the cooperative credit system. The analysis is conducted on a sample composed of 48 Italian banks, divided into 24 cooperative banks and 24 popular banks. The sample is made up of banks from all over Italy and very different in terms of dimension. For the sample construction, data relative to governance of banks were collected from the balance sheets in the period from June to August 2014. Financial-economic data were collected from the Financial Statements and from Bankscope database. The methodology of analysis is based on multivariate OLS （ordinary least squares） regression models. The main results refer to the presence of significant relationships between board dimension and the quality of loans and among the number of committees and performance and the quality of loans. The presence of a significant and negative relationship between the board dimension and the ratio of impaired loans to gross loans indicates the possibility that enlargement of board dimension allows a better quality of loans. The presence of a positive relationship between the number of committees and the ratio of impaired loans to gross loans signals the possibility that a greater number of committees can produce a worse quality of loans. The presence of a negative relationship between the number of committees and bank performance suggests to limit and manage the complexity of governance in banks operating in the cooperative credit system.展开更多

As a strategy of choice for many firms around the world, downsizing produces far-reaching financial, organizational, and social consequences. Despite the large body of literature, there is inconclusive evidence as to whether downsizing is effective and whether it generates the widely anticipated financial benefits. An in-depth review of the literature suggests that most downsized organizations have failed to yield economic benefits. This case study examined whether Portugal＇s eight largest banks realized their financial objectives upon the execution of downsizing activities during their recent 2008-2010 endeavors. Financial performance was measured through employee efficiency, profitability, and asset quality. Six hypotheses were defined using six different financial ratios which were deemed as integral tools for measuring financial performance of deposit-accepting banks. The secondary data were analyzed within a defined framework of two distinct phases： pre- and post-downsizing phases. A key statistical tool, the paired sample t-test, was applied to determine whether there were statistically significant differences in the ratios between the two timeframes. The analysis demonstrated that there were statistically significant differences between the pre- and post-downsizing ratios of loans per employee and deposits per employee. In contrast, no statistically significant difference was found in return on assets （ROA）, return on equity （ROE）, loans to assets, and non-performing loans to loans ratios. On the basis of this analysis, the study has concluded that downsized large Portuguese banks have largely failed to achieve their projected financial objectives.展开更多
