Our participation in joint ventures exposes us to liability and/or harm to our reputation for failures of our partners.
As part of our business, we have recently entered into joint venture arrangements and may enter into additional joint venture arrangements in the future. The purpose of these joint ventures is typically to combine skills and resources to allow for the performance of particular projects. Success on these jointly performed projects depends in large part on whether our joint venture partners satisfy their contractual obligations. We and our joint venture partners are generally jointly and severally liable for all liabilities and obligations of our joint ventures. If a joint venture partner fails to perform or is financially unable to bear its portion of required capital contributions or other obligations, including liabilities stemming from claims or lawsuits, we could be required to make additional investments, provide additional services or pay more than our proportionate share of a liability to make up for our partners shortfall. Further, if we are unable to adequately address our partners performance issues, the customer may terminate the project, which could result in legal liability to us, harm our reputation and reduce our profit on a project.
