Analysis and interpretation of financial statements

Hello All,

I was wandering if you have an accounts prepared on 18 month basis due to, say they changed year end from June to December, how do you look at the comparatives.

So the accounts are showing 18 months financial statement and the comparative given is for the 12 months prior years result. This is not a like for like comparative to interpret the accounts, what do you do in situations like this?

Thanks in advance for any reply!
