(1)Basis of Presentation

We prepared the accompanying condensed consolidated financial statements following the requirements of the Securities and Exchange Commission (“SEC”) and accounting principles generally accepted in the United States, or GAAP, for interim reporting.  As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP can be condensed or omitted for interim periods.  Balance sheet amounts are as of June 30, 2013 and December 31, 2012 and operating result amounts are for the three and six months ended June 30, 2013 and 2012, and include all normal and recurring adjustments that we considered necessary for the fair summarized presentation of our financial position and operating results.  As these are condensed financial statements, one should also read the financial statements and notes included in our latest Form 10-K for the year ended December 31, 2012.  Revenues, expenses, assets and liabilities can vary during each quarter of the year.  Therefore, the results and trends in these interim financial statements may not be the same as those for the full year.

Royalty revenue is recognized when the fees are fixed or determinable, which is known when we receive notice of the amounts earned pursuant to our third party royalty arrangements.  Typically, we receive notice of royalty revenues earned on a quarterly basis 30 to 60 days after the end of the reporting period.

Certain amounts for the previous periods presented have been reclassified to conform to the current period presentation.
