Limited time
The most knowledgeable and effective non-executive directors are likely to have other significant demands on their time. As directors they have to fulfil certain legal requirements. Apart from their contributions to the main board, they will also probably spend time at meetings of board committees such as the audit and remuneration committees. The limited involvement resulting from the lack of time may limit their ability to contribute to board meetings since they are unable to obtain a broad enough picture of what is happening throughout the organization.
