On October 1, 2019, Winter acquired Autumn, a small company that specializes in pharmaceutical drug research and development. The purchase consideration was by way of a share exchange and valued at P52.5 million. The fair value of Autumn s net assets was P22.5 million (excluding any items referred to below).

Autumn owns a patent for an established successful drug that has a remaining life of 8 years. A firm of specialist advisors, Summer, has estimated the current value of this patent to be P15 million; however, the company is awaiting the outcome of clinical trials where the drug has been tested to treat a different illness. If the trials are successful, the value of the drug is then estimated to be P22.5 million. Also included in the companys balance sheet is P3 million for medical related cost that has been conducted on behalf of a client.

Compute the amount of goodwill from this acquisition.
