A Group purchasing a new Co during the year

I was doing a question where it was asking for me to identify & expelling the implications of the acquisition of the new company. The areas that I focused on were its year end, its location (incase it was a foreign co), whether the auditor was familiar with its manufacturing process, how its goodwill was calculated (as no DCF was used). I noticed that in the answer there was loads more. Is there a standard answer that could be used for questions like this for they seem to come up quite frequently but I cannot understand how they can go to the lengths to get such an answer!
