What does "it is recommended that the directors' other business interests be reviewed" mean?

This comment denotes that the company has been scored down as a result of negative director data. However, because there are a number of elements in the scorecard relating to the directors' database it is not always possible to be specific.

We would recommend you to look for the negative information such as have any or a number of directors been involved with failed businesses in the past or have any of the companies in which the directors have an interest had County Court Judgments recorded against them?
