Reasons that the fee code would be reassigned to N by CDCB¶

1. No fee code was assigned, so the value becomes the default N
2. The animal has a sex conflict, so the value changes to N to prevent incorrect fee assignments
3. The animal has an abnormal/unreliable genotype, so the value changes to N and Usability of genotype is set to U
4. The animal has a duplicate conflict with another genotype and their genotype is Use=N, to prevent double billing when animals have been tested under different IDs
5. The animal had a low call rate - historical genotypes only , low call genotypes are now no longer uploaded to the database
