Pr00ne is correct. However, part of the "surplus" is also due to another aspect of Lean.
Think about it, You lean out a station to save money, but then you're left with 150 people (or however many) who you can't just sack but, having them as surplus is still costing you money!
Solution - put them on someone elses inventory!! "Lease" them to DARA, give them to the Navy get rid of them anyway you can! Look at how much money I've saved at my station!!
