Commitments and Contingencies	8. Commitments and Contingencies We are subject to litigation, claims and disputes in the ordinary course of business, some of which may not be covered by insurance. Management does not believe any of these matters will have a material adverse impact on the Company’s financial position or results of operations. There is an inherent risk in any litigation or dispute and no assurance can be given as to the outcome of any claims. In July 2015, we became aware that Hamylton Padilha, the Brazilian agent the Company used in the contracting of the Titanium Explorer drillship to Petrobras, had entered into a plea arrangement with the Brazilian authorities in connection with his role in facilitating the payment of bribes to former Petrobras executives. Among other things, Mr. Padilha provided information to the Brazilian authorities of an alleged bribery scheme between former Petrobras executives and Mr. Hsin-Chi Su who was, at the time of the alleged bribery scheme, a member of the Board of Directors and a significant shareholder of VDC. When we learned of Mr. Padilha’s plea agreement and the allegations, we voluntarily contacted the DOJ and the SEC to advise them of these recent developments, as well as the fact that we had engaged outside counsel to conduct an internal investigation of the allegations. Our internal investigation is ongoing and we are cooperating with the DOJ and SEC in their investigation of these allegations. In connection with our cooperation with the DOJ and SEC, we recently advised both agencies that in early 2010, we engaged outside counsel to investigate a report of allegations of improper payments to customs and immigration officials in Asia. That investigation was concluded in 2011, and we determined at that time that no disclosure was warranted; however, in the abundance of caution, we are reviewing the matter again in light of the allegations in the Petrobras matter. Although we cannot predict the outcome of this matter, if the DOJ or the SEC determine that violations of the FCPA have occurred, the Company could be subject to civil and criminal sanctions, including monetary penalties, as well as additional requirements or changes to our business practices and compliance programs, any or all of which could have a material adverse effect on our business and financial condition. Additionally, if we become subject to any judgment, decree, order, governmental penalty or fine, this may constitute an event of default under the terms of our secured debt agreements and result in our outstanding debt becoming immediately due and payable.

We enter into operating leases in the normal course of business for office space, housing, vehicles and specified operating equipment.
