Overview -- Autopista Monterrey Cadereyta's traffic volume has shown a recovery trend after repairs of hurricane-related damages were finished during the first half of 2012. -- We are revising our rating outlook on AMC's MXN2.25 billion senior secured notes to stable from negative. At the same time, we are affirming our 'BBB-' global scale and 'mxAA' national scale ratings on the notes. -- The stable outlook reflects AMC's adequate financial flexibility and positive trend in traffic volume, which will strengthen its operating performance during the next two to three years. Rating Action On Nov. 26, 2012, Standard & Poor's Ratings Services revised its rating outlook on Mexican toll road Autopista Monterrey-Cadereyta's (AMC) Mexican peso (MXN) 2.25 billion senior secured notes, issued by trust 80425, to stable from negative. At the same time, we affirmed our 'BBB-' global scale and 'mxAA' national scale ratings on the notes. The outlook revision reflects the positive trend of the toll road's traffic volume after all hurricane-related repairs were completed in the first half of 2012. In addition, the local and federal governments have been actively participating in several programs to reinforce the security in the Mexican state of Nuevo Leon, which has positively affected the toll road's traffic volume. Furthermore, the major maintenance reserve is again fully funded, increasing AMC's financial flexibility to face unexpected contingencies. MBIA Insurance Corp. (B/Negative/--) provides an unconditional and irrevocable guarantee of the full payment of principal and interest on the senior secured notes. Given that the Standard & Poor's underlying rating (SPUR) on AMC's senior secured notes is higher than the issuer credit rating on MBIA, the ratings on the notes reflect the SPUR. Rationale The ratings on the senior secured notes reflect the toll road's zero-cash-flow structure, in which excess cash after scheduled obligations is used to prepay principal; a projected average debt service coverage ratio (DSCR) of 1.61x; the trust's bankruptcy-remote structure; and the inelasticity that characterizes most of the toll road's users, given its status as a commuter road. The factors that constrain the ratings are the toll road's vulnerability to economic cycles and exposure to security issues in the region; the higher-than-average tariff per kilometer, which limits the toll road's ability to capture additional market share; and significant competition from the alternative free road to Monterrey's airport. AMC is a 30-kilometer toll road located in the state of Nuevo Leon and connects the cities of Monterrey and Cadereyta. Red Estatal de Autopistas de Nuevo Leon (REA; not rated) owns and maintains the road. REA is a decentralized public entity with more than 20 years of experience operating toll roads and other public infrastructure. Traffic volume on the toll road has shown a positive trend after all hurricane-related reconstruction works were completed. The positive trend also reflect, in our view, the security programs that the local and federal governments have established to reduce the security issues that began to hurt traffic volume at the start of the second half of 2011. For the 12 months ended Oct. 31, 2012, AMC's traffic volume increased 4.0%, and revenues increased 10.3%, benefiting from the tariff adjustments made on Feb. 15, 2012. We believe that AMC's traffic volume will continue to post a positive trend, supported by the region's economic growth and the improvement in security issues. Our base case scenario considers an average increase in traffic volume of 3.7% throughout the remaining life of the notes. This includes a moderate recovery in traffic volume related to security and tariff adjustments at the beginning of each year based on inflation. The senior notes are denominated in inflation-protected units (UDIs), creating a currency mismatch with revenues generated in pesos. We believe that this risk is partly mitigated as the sponsor, REA, has the right to adjust tariffs every year in line with annual inflation levels until the project repays the full amount of the debt. If inflation increases by more than 5% during a 12-month period, the tariffs can be adjusted again. However, we believe that, under a high-inflation scenario, REA wouldn't be able to increase tariffs by the full amount of inflation increase. Following the recovery operating performance, the trust was able to again fully fund the major maintenance reserve, increasing its ability to face another unexpected hurricane-related contingency or any security-related events. The next significant major maintenance is schedule for 2016, with an investment of MXN$62 million, according to independent engineer. Therefore, we expect that the trust will use available cash flow after debt service to prepay debt. The trust paid its 15th coupon on June 18, 2012, totaling MXN$91 million, including interest and principal, and it has not made any prepayments since June 2010. Considering the trust's legal waterfall, the last coupon payment DSCR was 1.41x, which compares adequately with its peers in the same rating category. The next coupon payment is scheduled for Dec. 16, 2012, and we estimate an average DSCR of 1.61x with a minimum of 1.26x, for the remaining life of the issuance. Under our base case scenario, we expect the trust to make a prepayment on the next coupon of about MXN20 million and to continue doing so in order to fully amortize the debt in June 2024--5.5 years before its programmed schedule maturity. Liquidity We consider AMC's liquidity to be sound. We believe that AMC's cash flow remains adequate and will allow expected average DSCR's of 1.61x throughout the remaining life of the notes. The toll road's financial structure includes a debt service reserve for any liquidity pressure that was funded upfront with issuance proceeds, and it amounts 12 months of debt service payments (interest and capital). As of Sept. 30, 2012, the balance of the debt service reserve account was MXN196.7 million plus an additional MXN8.4 million in a separate account funded with the issuance proceeds. Outlook The stable outlook reflects AMC's adequate financial flexibility and positive trend in traffic volume, which will strengthen its operating performance during the next two to three years. We could raise the ratings if higher-than-expected traffic volume and, therefore, toll revenues result in DSCRs above our average of 1.61x. We could lower the ratings if the toll road's traffic volume doesn't totally recover according to our expectations, leading to DSCRs consistently below our base case average, which would diminished AMC's financial flexibility.
