Here's the 2001 OKW breakout.
Operating Costs - $2.0649 per point
Capital - $.3466
Property Tax - $.7157
Dues Total -- $3.1272
When they are assessed the actual dues, if it is less, they will deduct that amount from the payment due for the 2002 dues. (I suppose they would also assess a difference if it went up but that hasn't happened to date.)
