Our business could be negatively affected if we incur legal liability in connection with providing our solutions and services.
If we fail to meet our contractual obligations, fail to disclose our financial or other arrangements with our alliance partners or otherwise breach obligations to clients, or if our subcontractors breach or dispute the terms of our agreements with them, we could be subject to legal liability. We may enter into non-standard agreements because we perceive an important economic opportunity or because our personnel did not adequately adhere to our guidelines. In addition, the contracting practices of our competitors may cause contract terms and conditions that are unfavorable to us to become new standards in the marketplace. We may find ourselves committed to providing services that we are unable to deliver or whose delivery will cause us financial loss. If we cannot or do not perform our obligations, we could face legal liability and our contracts might not always protect us adequately through limitations on the scope of our potential liability. If we cannot or do not meet our contractual obligations to provide solutions and services, and if our exposure is not adequately limited through the terms of our agreements, we might face significant legal liability and our business could be adversely affected.
