Is overseas income from previous job considered in HDB income ceiling calculation?

My partner and I are both Singapore citizens. I live and work in Singapore, my partner has been living and working in the US for the past 5 years. We wish to BTO, and she is planning to return permanently to Singapore.

Is her income while overseas considered in HDB income ceiling calculations? Or will her income be considered $0 since 1) she has no cpf contributions or taxes paid in the last 5 years and 2) she will be quitting the job overseas and moving back to Singapore.

Please help!! I cannot find any information on this specific topic.
