Basis of Presentation [Abstract]

Basis of Presentation

1. Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S.”) (“GAAP”) and, in the opinion of management, reflect all adjustments, consisting solely of normal recurring adjustments, needed to fairly present the financial results of SurModics, Inc. and subsidiaries (“SurModics” or the “Company”) for the periods presented. These financial statements include some amounts that are based on management’s best estimates and judgments. These estimates may be adjusted as more information becomes available, and any adjustment could be significant. The impact of any change in estimates is included in the determination of earnings in the period in which the change in estimate is identified. The results of operations for the three months ended December 31, 2011 are not necessarily indicative of the results that may be expected for the entire 2012 fiscal year.

In accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”), the Company has omitted footnote disclosures that would substantially duplicate the disclosures contained in the audited financial statements of the Company. These unaudited condensed consolidated financial statements should be read together with the audited consolidated financial statements for the fiscal year ended September 30, 2011, and footnotes thereto included in the Company’s Form 10-K/A as filed with the SEC on February 14, 2012.

Certain items in the condensed consolidated financial statements for the first quarter of fiscal 2011, and assets and liabilities as of September 30, 2011, have been reclassified to conform to the current period presentation. As discussed in Note 3, the results of operations, assets and liabilities of SurModics Pharmaceuticals, Inc. (“SurModics Pharmaceuticals”) have been accounted for as discontinued operations for all periods presented. Accordingly, the results of operations, cash flows, assets and liabilities of SurModics Pharmaceuticals for prior periods have been reclassified to discontinued operations.

Changes to Condensed Consolidated Statements of Operations

Beginning with this Form 10-Q for the first quarter of fiscal 2012, the Company has changed the format of the condensed consolidated statements of operations for reporting cost of revenue associated with research and development revenue. The change in format combines customer research and development expenses with other research and development expenses into the research and development expense category. Previously the research and development revenue exceeded ten percent of total revenue and as such Regulation S-X Rule 5-03 required presentation of an associated cost of revenue. With the presentation of the Pharmaceuticals segment as discontinued operations, the research and development revenue no longer exceeds ten percent of total revenue and as such there is no requirement to disclose a corresponding cost. All prior periods have been reclassified to present results following this new format.
