Fitch Rates Miami-Dade County, Fla.'s Aviation Revs 'A'; Outlook Stable

February 28, 2014

Fitch Ratings assigns an 'A' rating to Miami-Dade County, Florida's approximately $158 million aviation revenue refunding bonds series 2014, issued on behalf of the Miami-Dade County Aviation Department (MDAD).

In a release on February 25, Fitch noted that it also affirms the county's $5.82 billion parity aviation revenue bonds at 'A'. The Rating Outlook is Stable.

Key Rating Drivers

Leading International Gateway Airport: MIA is a well-positioned, leading international gateway airport to serve the building Latin America market. Despite shifting trends in the aviation industry and the presence of competition from nearby Fort Lauderdale Airport, overall traffic activity remains robust with approximately 19.9 million enplanements. The passenger base is well balanced for both origination/destination (O&D) and connecting passengers as well as international and domestic operations. American Airlines maintains a sizable connecting hub at Miami serving nearly 70 percent of total passengers. American's recently completed merger with US Airways removes the near term uncertainty over the carrier's future service decisions. The Miami air travel market is well anchored and the airport has a solid franchise for significant traffic activity. Revenue Risk - Volume: Midrange

Residual Rate Setting: All of the airport's costs are adequately covered by the use agreement rate setting mechanisms. The current agreement extends until 2017. While airline costs have been relatively high, with the estimated cost per enplanement (CPE) of slightly above $20 for fiscal 2013, updated CPE forecasts indicate stability at current traffic levels based on a combination of improving non-airline revenues and lower post-construction operating costs. Revenue Risk - Volume: Stronger

Conservative Debt Structure: All of the airport's debt is fixed rate and amortizing with a mostly level debt service through final maturity in 2041. Debt Structure Risk: Stronger

High Leverage and Modest Coverage: Very high airport debt levels (approx. $305 per enplanement and 13x net debt/CFADS) in conjunction past financings for a terminal driven $6.5 billion capital program. Leverage should slowly moderate over the next five years but still remain elevated at 11x - 12x. Debt service coverage ratios (DSCR) on a historical basis are stable at close to 1.45x but are supported by fund balance transfers and debt service offsets from passenger facility charge deposits. Future DSCR levels are expected to level off at around the 1.20x - 1.25x range.

Capital Program Completion: Nearly the entire $6.5 billion capital program has been expended and the overall budget has remained intact over the past several years. MDAD expects future needs will be far smaller in scale with no additional borrowing anticipated in the near term. Infrastructure Development/Renewal Risk: Stronger

Rating Sensitivities

--Material losses or increased volatility in aviation activity considering the particular exposure to the operations of American Airlines and the Latin American economies;

--Operating costs that trend materially above current forecast parameters, leading to upward revisions to airline costs;

--Development of a new capital program that results in increased leverage metrics.


The bonds are secured by net revenues of the county's Port Authority Properties (PAP), the main asset of which is MIA.

Transaction Summary

The county intends to issue up to $158 million in parity aviation revenue refunding bonds for the purposes of generating debt service savings. The bonds are expected to be issued in fixed rate mode with a final maturity in 2030.

MIA's enplanement activity continues to demonstrate growth with a positive change of 1.0 percent in fiscal 2013 to 19.9 million enplanements. The overall passenger traffic growth rates appear to be slowing from those seen several years ago although Fitch notes that the overall traffic resiliency reflects the relative strength of international traffic, particularly to Latin American markets that have close economic and cultural ties to the Miami metropolitan area. Expanded services from American are also a result of increased gate availability at the airport's North Terminal facility. The airport is served by a diverse mix of airlines, including ten scheduled domestic carriers, 38 scheduled foreign flag airlines, and 23 all cargo carriers. Miami's leading role for international operations is not only relevant for passenger operations but as well for air cargo. Miami currently ranks in the top two positions for U.S. airports in terms of nonstop international destinations and international air cargo tonnage.

Still, Fitch expects future traffic stability to remain an ongoing risk consideration given the high concentration of traffic from American's operations. American and its affiliate American Eagle collectively represents 68 percent of MIA's total passenger traffic and support a key part of the airport's domestic and international traffic operations. American's market share of total passenger traffic has remained mostly stable over the past several years. Even during the two year American bankruptcy period ending in late 2013, system-wide service capacity at the carrier has remained positive with international service expansion to Latin American markets being most beneficial for the airport. Fitch does not expect the recent American merger with US Airways to have material changes to the operational activities at MIA as there is very little overlap in domestic or international routes. Miami should remain a primary hub with significant base of international aviation activity.

In addition to general economic conditions, both domestically as well as internationally across Latin American regions, MIA's base of service also faces ongoing competitive threats for its domestic O&D traffic from nearby Ft. Lauderdale International Airport (FLL). FLL currently has a much lower cost profile and is served by a broader diverse mix of domestic legacy and low cost carriers. FLL is also undergoing a substantial expansion and redevelopment of both its airfield and terminal facilities, which could create a more challenging environment for MIA with regards to sustaining the traffic growth off its existing passenger traffic base.

Taking into consideration the airport system's residual rate- setting methodology, financial operations have been largely stable over the past several years with coverage of debt service holding in the 1.45x to 1.55x range, taking into account Improvement Fund transfers. Airline revenues account for about 50 percent of total revenues and have increased measurably in recent years to support the airport's growing cost base. However, non-airline commercial revenues have also risen in conjunction with the rising traffic levels. Otherwise, coverage is typically at or near the 1.2x - 1.25x range net of the use of such reserves. Based on the enplanement forecast (approximately 1.7 percent compounded annual growth rate through 2018) and the financial structure of the airport, projected coverage from net revenues to remain in the range of 1.2x to 1.25x through 2018. MIA's approximately $5.8 billion in senior-lien debt translates to approximately $305 per enplanement based on the 2013 traffic base but no additional debt is planned over the next several years to complete the funding of the current capital program. Estimated net debt to CFADS for fiscal 2013 is high for large hub airports at 13x but will ultimately moderate to a still elevated 11x - 12x level as airline costs are increased to meet the rising expenses even though annual debt service requirements are leveling. Airport unrestricted fund balances at about $297 million in FY2013, or 282 days cash on hand, have been largely stable but somewhat constrained given the residual airline agreements.

Fitch notes that the airport's current $6.5 billion capital program is nearly complete and remains at about the budget estimates indicated over the past several years. Key projects tied to terminal redevelopment have been completed including the new in-line baggage system to service the newly rebuilt North Terminal (Concourse D). At this time Fitch views the capital program risk to be minimal to the credit profile.

Airport CPE was $20.39 in fiscal 2013, a modest increase from $19.72 in fiscal 2012. These levels are generally high even for international gateway airports. However, the most recent CPE forecast report indicates materially lower growth trends as seen from previous projections. The combination of rising passenger levels, growing non-airline revenues, and containment in operating costs results in CPE rising to less than $22 - $23 range by 2018. Earlier forecasts assumed CPE levels rising to $30 and higher over the same time period. Fitch notes the airport's forecasted CPE may become a barrier to bring in new carrier service for domestic based traffic but is partially mitigated by higher yields typically attained by the airlines for international travel
