Impact of shadow file 'lastchg' parameter NULL or 0?

I've encountered shadow files where the "lastchg" parameters are set to NULL and also zero (0) for some Solaris machines (one running v10, one running v8).

I was wondering what impact this has on password ageing, and therefore enforced password change.

Does the NULL mean the account has never been logged on, and therefore the parameter never set?

Does the NULL mean the account is effectively disabled?

Does the NULL mean the account's password will never age as the calculation of age cannot be performed using a NULL?

Same questions for the zero (0).

Thanks in advance.
