Liquidity needs

When finalizing an IPS, What would be considered a threshold for time period to determine if the client has high liquidity needs?

A) 10 years

B) 5 years

C) None of the above

I was thinking that since 1 year is threshold for Current asset that might also be the case for Liquidity needs of PM’s client. Although realistically speaking even 2-3 years is a relatively short period for investment if liquidity is required after that
