How do Vistana proposed budgets add up?

[abdibile]

I got the proposed budgets for Vistana Resort Falls and Springs but do not get how they add up and what the total payment will be.

e.g. Falls, right colum (Unit Week Annual):

First box has revenues and expenses of $580.69

Then a small box with refurbishment project $640.42

The next box adds them up to "Total Operating Expenses & Refurbishment Project Fee" of $1,221

Until here I get it.

Then the box "Proposed budget of reserves for replacement" has revenues of $81.55 and expenses of $81.55.

Below it is a box saying "Total maintenance, Refurbishment & Reserve Fee" says $1,281.98

I have no clue where this sum is derived from.

Shouldn't it be $1,221 + $81.55 = 1,302.55 ?

Similar difference with SPrings section:

$1,225.11 (Operating & Refurbishment) + $95.48 (Reserve funding) = Total of $1,297.18 ????

Does not sound right.

Or what am I missing?

Thanks!
