Rating modifiers
Some letter ratings are further qualified by the addition of the symbols or letters below:

L Limited rating—Rating pertains to the principal amount of those bonds to the extent that the underlying deposit collateral is federally insured and interest is adequately collateralized.

PR Provisional rating—Assumes the successful completion of the project being financed by the debt being rated and indicates that payment or debt service requirements are largely or entirely dependent upon the successful and timely completion of the project. Upon receipt of the escrow agreement, a rating of AAA will be assigned.

*Continuance of rating is consistent with Standard & Poor's receipt of an executed copy of the escrow agreement of closing documentation confirming investments and cash flow.
