Adjusted Book Value
  
First see Book Value. And yeah, we have a very fine video on said subject.
So that's book value. What's the "adjusted" thing there? Well, yes, in fact, it is kind of like going to the chiropractor and having Helga twist your spine around. Adjustments to book value are tweaks both up and down that reflect things that weren't part of the normal course of business in you balancing your sheet.
The potential losses from that lawsuit when you sold Bag O' Glass as Garbage Bin O' Glass to elementary schools around the country? Yeah. That's a number that needs adjustment. You owe; you just don't know how much you owe, so you adjust each quarter as more information comes in.
Oh and you also invested in that acreage on which to break glass...the one right next to the prison. Turned out it had oil under it. Off balance sheet asset, that land. And every quarter they find more and more oil down there, so you adjust your book value.
