I have just started to look at this stock. Wife owns a few gas wells (small percentages) in KS and the wells are serviced by them. In my review, I found that the Accounts Receivable are up over 3.3 Million. Unless they have been paid down and not yet reported. Is anyone concerned about repayment. That bump in sales will only mean something if the A/R can be collected. Doesn't look like it is being repaid, at least funds flow seems not to have gone up. Just trying to see if this will be good investment?
