Looks like your concerns were warranted. I sold my majority of TBGVX in September. They made it a chore (need actual signatures no photo copies, miss-filing, etc.). I think they knew the handwriting was on the wall.
I am a long term holder and have been concerned about the dollar hedge ever since it became very apparent the US was headed for long-term decline with the resultant loss of its reserve currency status. I held nonetheless as a diversification move since the vast majority of my other investments were either directly overseas or in unhedged funds. While I still beileve in the long-term dollar decline, I hold TB just in case I am wrong about the dollar. They are as good a place as any for a solid dollar-denominated investment. Peter
