Description of Certain Indebtedness " for more information. Furthermore, the terms of any future debt we may incur could have further additional restrictive covenants. We may not be able to maintain compliance with these covenants in the future, and in the event that we are not able to maintain compliance, we cannot assure you that we will be able to obtain waivers from the lenders or amend the covenants.
Our credit ratings are periodically reviewed by rating agencies. These ratings, and any downgrades or any written notice of any intended downgrading or of any possible change, have and may affect our ability to borrow and may increase our costs of borrowings. Any failure to raise additional funds on favorable terms could have a material adverse effect on our liquidity and financial condition.
If we are unable to maintain existing, and establish new, arrangements with travel suppliers, or if our travel suppliers and partners reduce or eliminate the commission and other compensation they pay us or affect surcharges on TMCs, our business and results of operations would be negatively impacted.
Our business is dependent on our ability to maintain our relationships and arrangements with existing travel suppliers, such as airlines, hotels, car rentals, hotel consolidators, destination services companies and GDSs, as well as our ability to establish and maintain relationships with new travel suppliers. Adverse changes in key arrangements with our travel suppliers, including an inability of any key travel supplier to fulfill its payment obligation to us in a timely manner, increasing industry consolidation, changes in travel suppliers’ booking practices regarding groups, or our inability to enter into or renew arrangements with these parties on favorable terms, if at all, could reduce the amount, quality, pricing and breadth of the travel services and products that we are able to offer, which could adversely affect our business, financial condition and results of operations. In addition, decisions by airlines to surcharge the channel represented by TMCs, for example, by surcharging fares booked through or passing on charges to TMCs, or introduction of such surcharges to fares booked through the GDSs through which a material share of our content is sourced, could have an adverse impact on our business, particularly in regions in which our GDS is a significant source of bookings for an airline choosing to impose such surcharges. To compete effectively, we may need to increase incentives, pre-pay incentives, discount or waive product or service fees or increase spending on marketing or product development, which could adversely affect our business, financial condition and results of operations.
