By law to be tax exempt bonds, issuance costs can not exceed 2%. Therefore the 1% estimate could happen. Althought what could be interesting is to request that the Treas. require this to be a competitive bond underwriter selection as opposed to a "sole source" or negotiated bond underwriter deal.
Finally, I suspect that the warrants are toast for this fiscal year, which out to make for some interesting cashflow issues at the state.
Why do you suspect the Warrants are dead? That seemed like their way to delay the cash-flow problem until after the election.
