The maximum number of trustees is ten.

With the resignations of Chris Walters, David Smart and John Wood (see Companies House website) the number of trustees is seven leaving three vacancies.

One third of the trustees must stand down each year. The nearest whole number to one third of seven is two. So this year two trustees must stand down (and may stand again for election at the AGM)

Which means the number of vacancies in 2015 up for grabs is five.

We understand there are five candidates so far this year, not including the two “stand down” trustees, so we could have seven candidates in total.

All this is assuming no further resignations between now and the closing of trustee nominations for 2015.

Johnny Ball would be proud of us…or not, if we got our sums wrong.
