The 'Trasnsfer Agent' maintains a list of every registered owner of MSRM shares, whether in street name at a brokerage account, or under someone's bed. Any shares being traded now are registered to the new owners each time a sale is made.
On the day of conversion, all outstanding MSRM shares will be exchanged for 1 share of GBRC for each 7.143 shares of MSRM and issued to each registered owner (regardless of whether they were purchased two years ago or two days ago). Trading in MSRM shares will then stop.
The transfer agent does all the paperwork and if you still have possession of your certificates, you will have to submit them to the Transfer Agent for exchange. If they are in your brokerage account (street name), it will be done electronically.
The company (GBRC) is not involved and has no responsibility as all the new GBRC shares being exchanged are already issued and being held in the liquidating trust at the Transfer Agent.
