Target Wording of Scope 3 Portfolio Target Coverage

We are a financial group, and we own asset managers as our subsidiaries.
And we are preparing an SBTi target submission at the group level, including subsidiaries.

We have a question regarding the SBTi Submission Form - ‘3.1 Proposed Target(s) Wording’, Headline Target template of Scope 3 Portfolio Targets (below)

When calculating the coverage(%) of our group portfolio target, must we count both our own investment and AUM?
i.e. coverage(%)= (our own investment + AUM) included in our target / Our Total own investment + AUM

Many thanks,
