These are definitely TWO different issues.
1. The Exchange rate for the GXII merger is 11.1829212 NIOBF shares for every 1 GXII share.
2. The Reverse Splitting of stock rate for whatever, 3 to 1, 5 to 1, or 10 to 1 has yet to be determined, and will be decided AFTER the transaction. This reverse split is needed to make sure the stock dollar value is high enough to be listed on the NASDAQ without the fear of being delisted (dropping under $4.00 a share). I would think this would require at least a 10 to 1 reverse split to get the price then to around $10.00 a share.
