Appendix B also incorporates results for this new competing dangers, together with activities projected across the subset out-of fund that have negative equity in addition to subset out-of money based in exploration-unsealed regions
As a whole, multicollinearity should not be handled by the excluding related variables (because of omitted variable bias).
