A half-billion dollar settlement reached between Teva Pharmaceutical Industries Ltd. and the US government last week for the resolution of criminal charges in the bribery of officials in Russia, Ukraine and Mexico raises questions about the fate of other Teva bribery probes, in Argentina and Romania. Teva and the US Department of Justice said in separate statements on Thursday that they had reached a settlement over the charges relating to Russia, Ukraine and Mexico, and that Teva would pay a combined total of US criminal and regulatory penalties of almost $520 million.
