This has to do with Nevada corp, if it matters...
First of all, it's my understanding that in accounting practice, a share that is bought back and "retired" is removed from circulation forever. It does not even go back to the treasury. If that is correct, then here is my question: Say the corporation has 1000 shared authorized. All 1000 are in circulation. They buy back 500 and retired them. Can the corp issue a new set of 500?
