4. Ownership structure Consider an ownership structure (involving two firms A and B) where Company A owns 50% of Company B's shares, and Company B owns 25% of Company A's shares. The controlling family owns 1\% of Company A's shares, 1% of Company B's shares, and manages Company A and B by holding the CEO position in these companies. If you need, the formula for infinite sum is: (1+x+x2+x3+x4+x5+x6+.)=1/(1x). 4.
