Okay. I think I've remembered the questions.
First of all, with respect to the number of people we've hired, we directly employ about 100 people in Colombia—96% of them are Colombians, the other 4% are ex-pats.
As far as the number of people we employ in our operations in the field, a huge majority of our operations are conducted through third-party contractors. We currently have three drilling rigs working for us and a typical drilling rig would employ about 100 to 150 people through all the different subcontract groups, so it's in the range of another 300 to 500 employed in that. We also have a full-time seismic crew running, which probably has a contingent of about 100 to 120 people involved, again primarily third-party contractors.
The working conditions for everyone I think are very good. Certainly the local staff in our office command salaries that are very commensurate with Canadian salaries. The professionals are well paid and in huge demand. They're very capable people.
None of our direct employees is unionized. Very few of the people in the contracting industry are unionized. Not unlike Canada, the preponderance of unionization is in the public sector in Colombia.
Finally, with respect to the question about more social responsibility, oversight associated with a free trade agreement, I don't think we would have any problem with a normalization of corporate social responsibility in setting some minimum standards and so forth. I think one of the greatest things Canada has to export is our ability to actually deal in a multicultural sense and to deal with the competing parties in any type of a business negotiation and to find a win-win solution. I think that's really what corporate social responsibility is ultimately going to be about.
If I could take 30 seconds, I just want to clarify that the amount of money we're investing in the social responsibility part of our business during the investment phase will actually change over time. As we reduce the level of investment after a field has been developed, we then will shift our investment to a non-profit foundation we've set up called Fundación Vichituni, which will continue with some of the initiatives we've begun, but which, ultimately, we hope, will become self-sustaining and will not require over the long term the support of Petrominerales to be a success.
