They sold some of their holding to have money available to convert options they had. When you convert an option, you pay money at a certain strike price and you gain a share (usually 1 option to 1 share). The money you pay goes to the company, hence the cash inflow in to DW8.
If we take PE for example, he would have sold x amount of shares, probably in the realm of $200k+ worth at least at market prices ( more if he takes CGT into consideration). Then used $211,538 of what he sold to convert options he had. This money goes straight into DW8 bank.
The reason that this is a positive sign is that 1) support for the company from the directors; they have sold down some of their holding to convert options, risk/pay capital gains tax, but in return they are giving a substantial amount of working money to the company. 2) they are increasing their holding of actual shares (except DT, but net change less than -1% so that is minimal). Remember, they had the choice to let options expire and then there would be nothing for the company.
The negative is that there is somewhat realised dilution yet again (albeit small). I don't know the figures would have to read the annual report.
Most people do not have that amount of cash lying around to convert that amount of options without selling down other investments so it is very acceptable and announcement worthy.
Hope that makes sense! Read up on options if you are confused.
Cheers
