Why has BPF tanked over past year?

I very foolishly followed a bit of investment advice that if you know an industry well then invest in companies you trust. Following that advice in Feb 2014 I invested in BPF at 0.399 and now over a year later I've lost 50%, at this point I'm only holding on because I'd like the capital losses to show up in the next tax year.

For a company that seems to be doing so well why has the share price tanked so badly?
