N.Y. Private Activity Bond Law § 10
On or before October first of each year, each state agency shall report to the director and each local agency and each other issuer shall report to the commissioner the amount of bonds subject to allocation under this act that will be issued prior to the end of the then current calendar year, and the amount of the issuer's then total allocation that will remain unused. As of October fifteenth of each year, the unused portion of each local agency's and other issuer's then total allocation as reported and the unallocated portion of the set-aside for state agencies shall be recaptured and added to the statewide bond reserve and shall no longer be available to covered bond issuers except as otherwise provided herein. From October fifteenth through the end of the year, each local agency or other issuer having an allocation shall immediately report to the commissioner and each state agency having an allocation shall immediately report to the director any changes to the status of its allocation or the status of projects for which allocations have been made which should affect the timing or likelihood of the issuance of covered bonds therefor. If the commissioner determines that a local agency or other issuer has overestimated the amount of covered bonds subject to allocation that will be issued prior to the end of the calendar year, the commissioner may recapture the amount of the allocation to such local agency or other issuer represented by such overestimation by notice to the local agency or other issuer, and add such allocation to the statewide bond reserve. The director may likewise make such determination and recapture with respect to state agency allocations.
