Approximately $8.8 million of rated debt affected
New York, January 17, 2020 -- Moody's Investors Service has upgraded Metropolitan Knoxville Airport Authority, TN's (authority) Local Government Public Improvement Bonds (Revenue Program V), Series V-A-1 to A3 from Baa1. The outlook is stable. The bonds were originally issued by the Sevier County Public Building Authority, TN.
RATINGS RATIONALE
The upgrade to A3 reflects the strong enplanement growth at McGhee Tyson Airport (TYS or airport) in recent periods, which has directly resulted in improved financial performance. Additionally, the authority successfully eliminated its exposure to variable interest rates by refunding the vast majority of the Series V-A-1 bonds with a $39.6 million fixed rate note with Branch Banking and Trust Company (BB&T, A1 (cr)) in the first half of 2019. The Series V-A-1 outstanding $8.8 million balance as of June 30, 2019 is fully hedged through its 2021 maturity via a swap with Raymond James Financial Products.
Enplanements reached a new record in fiscal 2019 at 1.2 million, as American Airlines Group, Inc. (LT Corporate Family Rating, Ba3 stable) and ultra-low cost carrier Allegiant Air have stimulated significant passenger growth at TYS by supplementing existing service (Miami and New York-LaGuardia), adding new routes to non-traditional markets (Pittsburgh and Denver) or upgrading to larger aircraft on existing routes. The local economy generates an adequate amount of demand for air travel originating in Knoxville but there also is a healthy amount of tourists coming to the region in order to visit the Great Smoky Mountain National Park, the most visited national park in the US according to the National Park Service. The Knoxville regional economy is anchored by a significant number of major employers in an array of industries ranging from healthcare, manufacturing, universities, and government institutions. The authority's master plan assumes an annual enplanement growth rate of 2.4% going forward, which we believe is reasonable. Enplanements have increased 18.8% through the first four months of fiscal 2020 through October.
Higher passenger throughout has resulted in increasing non-aeronautical revenues and stronger financial metrics such as the debt service coverage ratio (DSCR). The authority's net revenue DSCR reached 2.22x in fiscal 2019, up from 1.97x in fiscal 2018 and 1.74x in fiscal 2017. Given the expectation of continued enplanement growth at the airport, relatively level debt service schedule and no additional debt needed to fund capital improvements in the near term, we expect the authority's net revenue DSCR to remain at or exceed 2.0x going forward. Liquidity remains a key credit strength for the authority and reached 906 days at fiscal year-end 2019.
The A3 rating also considers the competition for passengers within the air service area from much larger airports like Nashville and Atlanta, both of which are within a reasonable driving distance between two and three hours. Additionally, the rating also factors in the lack of an indenture required 12-month cash-funded debt service reserve fund for all of the outstanding series of debt and fixed rate notes. However, Moody's acknowledges the fact that the authority strives to maintain a debt service reserve fund of around two times the current debt service balance, including interest.
RATING OUTLOOK
The stable outlook considers our expectation of conservative budgeting and management practices that results in strong financial performance with DSCRs above 2.0x and liquidity above 600 days cash on hand.
FACTORS THAT COULD LEAD TO AN UPGRADE
- Significant expansion in the regional economy that produces sustainable enplanement growth above the national average
- Meaningful expansion in air service offerings combined with increased competition and lower average airfares and airline costs
- Introduction of a debt service reserve fund for all outstanding series of debt
FACTORS THAT COULD LEAD TO A DOWNGRADE
- Net revenue DSCR below 1.75x on a sustained basis
- Liquidity below 600 days on a sustained basis
LEGAL SECURITY
The bonds are secured by the net revenues of the authority pursuant to loan agreements between the authority and the Public Building Authority of Sevier County (PBA). The PBA is a conduit issuer. The bonds are secured by a rate covenant that requires the authority to maintain rates and charges sufficient to provide for 1.2x of debt service requirements. There is also an additional bonds test in which net revenues must exceed 120% of debt service requirements, either prospectively or retrospectively. There is no indenture required debt service reserve fund for any of the outstanding bonds.
