I've attached the most recent copy of the budget (and also uploaded this to the admin team dropbox).
This includes the confirmed Insurance amount and an additional $30,000 for tree work.
Due to the tree work we are now eating into our cash reserves (by about $10,500 of the $40,000 that we had in the bank at the lowest point over the past year). Cashflow might also be a problem depending on the timing of payments. Hopefully some of the tree work can be invoiced and paid after the festival (once we receive our final draw-down from Cosmic).
Despite the cash deficite, we're still turning a profit because of the spending on capital items. This means that we'll still have income tax bills to pay next year. As this isn't due until after the event it shouldn't be a problem.
