How "never voted on" is worked out

Normally a person's votes count towards a score which is used to work out a simple phrase to summarise their position on a policy. However in this case Ron Boswell was absent during all divisions for this policy. So, it's impossible to say anything concrete other than that they have "never voted" on this policy.
