Regen BioPharma Inc (RGBP)

[Cooway]

I finally got the Filings up on my phone. Was reading through the filing from 4-19 and saw that RGBP hired a firm to do an audit. (See below)

"Regen executed an engagement letter with BF Borgers CPA PC ( “Borgers”), the Company’s independent registered public accounting firm, the purpose of which was to retain Borgers to perform an audit of the Company’s balance sheet"
Is that really necessary on the OTC? I thought using a firm for an "audit" was really expensive and NOT necessary to get Pink Current on the OTC. Why would a broke company like RGBP do that just to get Pink Current? Seems like an unecessary expense for a company with no real value. What am i missing here?
