In addition, cash generated from the sale of used gaming equipment classified as leased gaming equipment is also included in cash provided by operating activities in the consolidated statement of cash flows. The Company has one process to procure raw materials for the assembly of both inventory and leased gaming equipment. The materials requisition planning process considers the number of devices the Company expects to build for sale and for use in its gaming operations division during a particular period, but it does not separately earmark purchases for leased gaming equipment. Without such an earmarking process, the Company is unable to determine whether the parts used to construct leased gaming equipment during a particular period came from inventory on hand at the beginning of the period or was constructed from inventory procured during the period of deployment, thus requiring the expenditure of cash.28CONDENSED CONSOLIDATED SUPPLEMENTAL CASH FLOW INFORMATION (USD $)ThousandsUnKnownUnKnownUnKnownfalsetrue
