in ASC 860, Transfers and Servicing , as we are considered to have surrendered control of these financing receivables.

In addition, we enter into arrangements with leasing companies for sale of our hardware systems products. These leasing companies, in turn, lease our products to end-users. The leasing companies generally have no recourse to us in the event of default by the end-user and we recognize revenue upon delivery, if all the other revenue recognition criteria have been met.

Our customers include several of our suppliers and occasionally, we have purchased goods or services for our operations from these vendors at or about the same time that we have sold our products to these same companies (Concurrent Transactions). Software license agreements or sales of hardware systems that occur within a three- month time period from the date we have purchased goods or services from that same customer are reviewed for appropriate accounting treatment and disclosure. When we acquire goods or services from a customer, we negotiate the purchase separately from any sales transaction, at terms we consider to be at arm’s length, and settle the purchase in cash. We recognize new software license revenues or hardware systems product revenues from Concurrent Transactions if all of our revenue recognition criteria are met and the goods and services acquired are necessary for our current operations.

Business Combinations

In fiscal 2010, we adopted ASC 805, Business Combinations , which revised the accounting guidance that we were required to apply for our acquisitions in comparison to prior fiscal years. The underlying principles are similar to the previous guidance and require that we recognize separately from goodwill the assets acquired and the liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions as a part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations.

Accounting for business combinations requires our management to make significant estimates and assumptions, especially at the acquisition date with respect to intangible assets, support obligations assumed, estimated restructuring liabilities and pre-acquisition contingencies. Although we believe the assumptions and estimates we have made in the past have been reasonable and appropriate, they are based in part on historical experience and information obtained from the management
