Small differences can still fall within approximately the same proportion, but the petition must show the numbers and explain the gap rather than smoothing it over. Larger divergences may need the structure fixed before filing.
Show the mismatch, then explain it
Hypothetical example: the Hampton siblings own the Canadian company fifty-fifty, but in the U.S. entity one holds fifty-five per cent and a former colleague holds five per cent as a founding stake. The instinct is to describe both as jointly owned and move on.
That is the description most likely to draw a request for further evidence, because an officer who obtains the registers will see the difference before any explanation is offered. The stronger approach is a table showing both companies, every holder and every percentage, followed by a short explanation of how the five per cent arose and why the two pictures remain substantially aligned. If the divergence is large enough to break the claim, buying back the minority stake before filing is a cleaner solution than an argument about the word approximately.
