Jimbo,
This is from the RES website about director buying. Basically they can't due to these conditions at the moment.

The only appropriate time for a director or employee to acquire or sell the Company’s shares is when he or she is not in possession of price sensitive information which is not generally available to the market.

In addition, to avoid any adverse inference being drawn of unfair dealing, directors and employees should not deal in the Company’s shares during the month immediately before the release of the Company’s half-yearly or yearly results or in the month immediately before the Annual General Meeting when it is customary for the Chairman to provide further information about the Company’s current performance.
