New York, November 08, 2019 -- Moody's Investors Service has assigned an A1 rating to the City of San Antonio, TX Airport Enterprise's $85.2 million Airport System Revenue Refunding Bonds (GARBs), Series 2019A (AMT) and Taxable Series 2019B. We have also assigned an A2 rating to the $95.5 million Passenger Facility Charge and Subordinate Lien Airport System Revenue Refunding Bonds, Series 2019A (AMT) and Taxable Series 2019B. Concurrently, we have affirmed the A1 and A2 ratings on the $295 million of outstanding senior and PFC/subordinate lien debt, which includes the bonds being refunded, as well as the A3 rating on the City of San Antonio, TX - Airport Consolidated Rental Car Special Facilities Project's $123 million Customer Facility Charge (CFC) revenue bonds. The outlook is stable.
RATINGS RATIONALE
The assignment and affirmation of the A1 rating on the senior lien revenue bonds reflects the overall strength of the airport's service area with a large, stable and diverse economy; mixed set of air carriers with some concentration by Southwest Airlines; and improving financial metrics given the recent trend of strong enplanement growth. However, we expect longer term growth rates will be curbed by the low average wage of the region and leakage of passengers to Austin. The enterprise's leverage measured by debt plus Moody's adjusted net pension liability (ANPL) is a moderate $90 per O&D enplaned passenger, though not exceedingly high compared with the sector-wide trend of significant additional debt issuance to fund capital plans. The development of a long-range master plan is currently underway, which could entail a sizeable amount of new debt.
The assignment and affirmation of the A2 rating on the PFC and subordinate lien revenue bonds has a one-notch distinction from the senior bonds. This reflects the subordinate pledge and lack of rate raising ability on the PFC, although PFC collections currently provide strong coverage on subordinate lien debt service if considered on a standalone basis.
The affirmation of the A3 rating on the CFC bonds considers the fundamental strength of the airport's service area, limited collection history yet solid revenue trend after the ConRAC facility officially opened in January 2018. The rating additionally considers the strong bondholder protection features including the ability to charge contingent rent to car companies and the City in the event that CFC collections fall short, as well as performance guarantees from operators. The CFC rate ($5.50 per transaction day) is within the standard range with room for increase if necessary. The ConRAC system benefits from adequate liquidity in the form of rolling coverage, surplus and renewal and replacement funds. The long-dated structure of the CFC debt is exposed to long-term technological disruptions like widespread passenger use of autonomous vehicles and thus negatively weighs on the rating.
RATING OUTLOOK
The stable outlook on the senior and subordinate lien bonds reflects our expectation that continued economic expansion in the San Antonio region will drive enplanement growth. Moderate enplanement growth will support stable to improving financial metrics given the flat debt service profile on airport revenue bonds. The stable outlook on CFC bonds is based on the expectation that the current trend of CFC collections will remain stable over the near term.
FACTORS THAT COULD LEAD TO AN UPGRADE
- Enplanement growth well above the national average for all airports
- Total net revenue debt service coverage exceeds 2.0x on a consistent basis while maintaining current liquidity levels for both GARBs and CFC bonds
- Liquidity above 4x annual debt service requirements for CFC bonds
FACTORS THAT COULD LEAD TO A DOWNGRADE
- Decrease in enplanement growth rates or passenger declines that compromise debt service coverage and CFC collections in a sustained manner below the airport's anticipated levels
- Continued decrease in debt service coverage by net revenues that would result in debt service coverage below 1.25x on a sustained basis on GARB bonds, 1.5x on for the CFC bonds
- Significant debt-funded expansion without a long-term airline agreement
LEGAL SECURITY
The senior lien revenue bonds are secured by a pledge of gross operating revenues derived from the operation of the city's airport system secure the airport system revenue bonds, on parity with outstanding senior lien debt. The senior lien revenue bonds debt service reserve funds requirement is equal to average annual debt service requirements. The required reserve on the portion of the parity debt funded by CFC revenues is equal to maximum annual debt service.
The PFC/subordinate lien revenue bonds are secured by a first lien on all PFC revenues and a first lien on all subordinate revenues of the airport system. The debt service reserve requirement is equal to average annual debt service. The 2019 refundings will terminate the reserve fund surety policies acquired in connection with the Series 2005 and 2007 bonds.
Secured by the assets of the Trust Estate pledged by the City which encompasses: first lien and security interest on (i) CFC revenues, (ii) lease agreements, (iii) performance guarantee revenues (equivalent to 6 months of estimated CFC revenues and ground rent from rental car companies) and contingent fees (additional payment obligations required to be paid by the Operators and the City in the event of shortfalls) and (iv) the amounts in the construction, revenue, debt service, debt service reserve, coverage, renewal and replacement and surplus funds. One third of the performance guarantee revenues may be in the form of a letter of credit with the remainder in a surety bond.
The CFC bonds benefit from a MADS reserve fund, an initial $7.5 million CFC Renewal and replacement fund which if depleted may be replenished over a period of 60 months, a 25% of MADS rolling coverage ($2.4 million) and a CFC surplus fund.

PROFILE
Originally built in 1941 as a military base, San Antonio International Airport became a commercial airport in 1953. The airport occupies approximately 2,600 acres of land and is located eight miles north of the City of San Antonio's downtown business district. The city owns and operates the Airport System. The Airport System includes the City of San Antonio International Airport and Stinson Municipal Airport, which is primarily a general aviation airport, including all its land, buildings, structures, equipment, and facilities.
San Antonio International has three runways, the largest one measuring 8,500 feet in length and 150 feet wide, two passenger terminals with abutting apron areas for aircraft parking; two terminals with 24 gates and approximately 623 square feet including: hold rooms, operations, ticketing, and common areas; concessions; aviation offices, and pedestrian access to existing parking facilities. Stinson is located five miles outside of the city, and is a designated general aviation reliever airport for San Antonio International. The airport is classified as a medium-hub airport by the Federal Aviation Administration (FAA) and is the only commercial service airport serving the City and the San Antonio metropolitan area.
The San Antonio International ConRAC opened for business in January 2018. The 1.8 million square feet facility houses up to 14 rental car companies, a quick turnaround area for fueling, vacuuming, washing and light maintenance and approximately 2,600 ready/return parking spaces. ConRAC is within walking distance to the Airport terminals, eliminating the need for shuttles to take passengers to their rental car locations, thus enabling the Airport to initiate significant improvements to traffic flow in the arrivals area.
