    Recently Issued Accounting Pronouncements
 
    Effective January 1, 2011, the Company adopted new accounting guidance which addresses how to determine whether a sales arrangement involves multiple deliverables or contains more than one unit of accounting, and how the sales arrangement consideration should be allocated among the separate units of accounting. The Company evaluated this new guidance and the adoption did not have an impact on the Company’s financial position or its results of operations.
