Yellow was cash poor and had negative cash flow. You guys are over complicating it. They became “cash poor” from always having negative cash flow and look what happened.Dokman, you're over complicating a simple concept. Cash flow is either cash or equivalents coming in or cash or equivalents going out. Net cash flow is cash in minus cash out, period. It has nothing to do with assets behind the scenes. As EX396 has stated it, you can be quite wealthy with assets but have negative net cash flow, or your can be asset light with positive net cash flow. Yellow was cash poor, i.e., they lacked sufficient cash on hand (liquidity) to pay their current obligations. They did however have sizeable wealth tied up in real estate, equipment, etc. as we're seeing in the BK.
Don’t care if you are starting out or in retirement if you don’t have enough money coming in to put back for later, you will always be paycheck to paycheck and eventually in over your head. I think I have a very good grasp on cash flow thanks for trying I plan to stick with the motto, “spend less than you have and you will have more than you need someday.”
