$XMET 8-k math example if exact 93% voting rights contained in Preferred Shares
1PS=100 voting rights
1CS=1 voting right
100M PS = 10B voting rights
100M PS = 93% voting rights
10B(PS voting rights) / .93 = 10752688172 total voting rights
10752688172-10B(voting rights PS) = 752688172 voting rights/common shares in float.
However if you base the math to include the difference of valid / invalid shares
9B valid -- 8,197,627,462 invalid = 802372538 shares. That still gives Wei Tian an approximate 93% voting rights with 100M preferred shares... 100M * 100 = 10B + 802372538 = 10802372538.
10000000000 / 10802372538 = roughly 92.57% or an approximate 93% voting rights.
Clearly approximately 8.2B common shares are still not counted in the voting rights and it's possible the float only consists of these shares.
