Check that the percentages can be added
Assume three fictional investors report direct, non-overlapping holdings measured against the same outstanding share base at the same date. Their stakes are 1.5%, 2.2% and 1.6%. The matching base matters: adding an economic-interest percentage to a voting-rights percentage would not automatically produce a valid aggregate voting stake.
Add the three stakes
The sum is 1.5 + 2.2 + 1.6 = 5.3 percentage points of the stated share base. Suppose this fictional collaboration platform sets a 5% participation condition. The group meets that stipulated condition by 0.3 percentage points. The condition is part of the exercise, not a securities-law filing threshold.
| Member | Stake | Cumulative stake |
|---|---|---|
| A | 1.5% | 1.5% |
| B | 2.2% | 3.7% |
| C | 1.6% | 5.3% |
Check the effect of one member leaving
Without A, the total is 3.8%; without B, it is 3.1%; without C, it is 3.7%. Every two-member group falls below this exercise’s 5% condition. Those subtotals provide an arithmetic check and show why the membership assumptions matter.
Separate ownership from the engagement result
An aggregate stake does not establish that the group has agreed on an objective, can vote together or will achieve an issuer change. Coordination arrangements and applicable restrictions need their own assessment. This calculation answers only the stated aggregation question.
