Item No. 10a supp Meeting Date: March 24, 2026 Subordinate Lien Revenue Debt Refresh March 24, 2026 1 Commission Actions • Adoption of the Subordinate Lien Master Resolution No. 3845 - Establishes key credit provisions that will apply to all Subordinate Lien Revenue Bonds • Amendment of the two Series Resolutions for currently outstanding Subordinate Lien bonds - Incorporates changes in the Master Resolution Note: Actions today do not include any new bond issue authorization - Likely Commission request for new bond(s) later this year 2 Background • Subordinate Lien was established in 1992 - Debt service obligations on Subordinate Lien bonds are paid from the Port's net revenues after payment of First Lien and Intermediate Lien obligations • Beginning in 1997, the Subordinate Lien has been used primarily for variable rate debt backed by bank credit • Only ~4% of the Port's total debt portfolio is variable rate (all on the Subordinate Lien): - Commercial Paper Notes - total authorized, $400 million ($120 million outstanding) - 2008 Variable Rate Demand Bonds - $110 million outstanding 3 Purpose • Staff is proposing updates that will make the subordinate lien more usable and easier to manage - Certain provisions are now out of date or inconsistent with other liens • Refresh will help pave the way for future issuance of Subordinate Lien variable rate debt - The Port can improve its overall debt management by issuing more variable rate debt - see appendix for additional details on variable rate 4 Key Updates Topic Legal Structure Current New Purpose Each series of bonds is governed by its own bond resolution Similar to the First and Intermediate Liens, a Master Resolution will govern material provisions, and a series resolution will govern the mechanics of each series of bonds Clear consistency of primary credit provisions Debt Service Coverage 1.0x based on the subordinate lien alone (income after First and Intermediate Lien bonds are paid) divided by the subordinate lien debt service 1.0x based on aggregate coverage - net income of the Port divided by the debt service of all liens Aggregate coverage provides a clearer and more meaningful calculation Debt Service Offsets PFCs and CFCs did not exist when lien was formed The Port may use off sets such as PFCs and CFCs to reduce debt service in the coverage calculation Flexibility to use off sets Additional Bonds Test 1.5x coverage based on the subordinate Lien only 1.05x aggregate coverage or 1.10x if debt service off sets are pledged More flexibility to issue new debt 5 Process Step Status Input from Port's investment banking team on recommended changes to the subordinate lien Consent by Bank of America and Sumitomo - Letter of Credit providers on the Port's outstanding Subordinate Lien bonds and notes Commission Authorization Confirmation from Rating Agencies Extension of Letter of Credit on Series 2008 Bonds Completed In Progress March/April April April 6 Commission Action • Request Introduction on March 24, 2026 • Request Adoption on April 14, 2026 1.

Adopt Series Resolution No. 3847 - 2008 Variable Rate bonds • Amends Subordinate Lien Series Resolution No. 3598 7 Appendix - Variable Rate Debt 8 Variable Rate Debt Can Lower the Port's Cost of Capital • Variable interest rates reset frequently, e.g. each week • Short-term municipal rates on average are lower than longterm rates Average Rates 2000-2025 SIFMA MMD 1.48% 3.54% - SIFMA: Securities Industry and Financial Market Association Index of municipal short-term rates - MMD: Municipal Market Data index of long-term rates 9 Other Benefits Asset-Liability Management • Reduce interest rate risk by hedging interest expense and interest earnings Flexible Structure • Some variable rate products provide for flexible principal payments 10 Rate Volatility is a Risk • The Port retains interest rate risk, but manages that by off-setting variable rates on its investment portfolio 11 The Port Retains Credit and Liquidity Risk Risk Mitigation • The Port's variable rate is backed by a bank letter of credit • Problems with the market or problems with the bank's credit can result in higher rates or in a lack of investors • The Port negotiates agreements with the bank(s) to minimize the increase in rates and to provide time to cure the underlying problem • Diversify bank exposure - The Port experienced this during the credit crisis in 2008 12
