the 'Main Applicant' section in Tier 1 Investor Visa Child

In the online application for Tier 1 Investor Visa Child there is the 'Main Applicant' section where there are the following questions:
- What job/course of study is the main applicant doing in the UK?
- What is the address where the main applicant works or studies?
However, the main applicant, who is an investor, does not work. What would you advise to fill in the form?
Thank you in advance,

Just choose the closest one and explain in the additional information section at the end of the form, silly form :-S
