Summary of Bond Underwriting Process – Series 2019 Refunding Bonds  Prior to entering the market with NISD’s Series 2019 Refunding Bonds, 3 Texas school districts (Katy ISD, Lubbock ISD and Barbers Hill ISD) had already priced over $300 million of “taxable” PSF-guaranteed bonds that week, providing a “road map” for the District’s bond sale. With a Federal Reserve rate cut announcement looming, the District’s underwriting syndicate elected to pursue an aggressive pricing strategy to achieve interest rates that were commensurate or below these comparable bond sales.  The “aggressive” pricing strategy, coupled with skepticism surrounding the U.S. and China reaching a trade deal which sent “taxable” yields sharply lower, ultimately served the District well, as NISD achieved the lowest interest rates of all comparable Texas school districts that sold “taxable” bonds during the week.  The District’s Series 2019 Refunding Bonds were initially sold to 14 diverse institutional investors.
