Think of it this way. Pink sheet tier stocks are the bottom of the barrel stocks. It's like a casino down here. The fact that ARNH went from limited reporting to current reporting really doesn't mean anything to the bottom line of the company. The reporting requirements for pink sheet stocks are minimal. So just the fact that they are current just means that their filings are up to date.
Remember, they are UNAUDITED filings.
That said, there are some pinks that are always behind in reporting so at least ARNH is current and you have an idea of what the company has been up to this year. Also, current reporting will help this stock get promoted when the time comes.
Good luck trading.
