Note 1 – Basis of Presentation

The accompanying consolidated financial statements include the accounts of Enzo Biochem, Inc. and its wholly-owned subsidiaries, Enzo Life Sciences, Enzo Clinical Labs, Enzo Therapeutics and Enzo Realty LLC, collectively referred to as the “Company” or “Companies”. The consolidated balance sheet as of January 31, 2013, the consolidated statements of operations and the consolidated statements of comprehensive income (loss) for the three and six months ended January 31, 2013 and 2012, the consolidated statements of cash flows for the six months ended January 31, 2013 and 2012, and the consolidated statement of stockholders’ equity for the six months ended January 31, 2013 are unaudited. In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position and operating results for the interim periods have been made. Certain information and footnote disclosure, normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States, have been condensed or omitted. The consolidated financial statements should be read in conjunction with the consolidated financial statements for the year ended July 31, 2012 and notes thereto contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission. The consolidated balance sheet at July 31, 2012 has been derived from the audited financial statements at that date. The results of operations for the three and six months ended January 31, 2013 are not necessarily indicative of the results that may be expected for the fiscal year ending July 31, 2013.

Recent Accounting Pronouncements Adopted

In June 2011, the FASB issued Accounting Standards Update No. 2011-05, “Comprehensive Income” (Topic 220) – Presentation of Comprehensive Income” (ASU No. 2011-05), which requires an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminated the option to present the components of other comprehensive income as part of the statement of stockholders’ equity. The Company adopted ASU 2011-05 in its first quarter of fiscal year 2013 by including the required disclosures in two separate but consecutive statements.

In September 2011, the FASB issued Accounting Standards Update No. 2011-08 “Testing Goodwill for Impairment” (ASU No. 2011-08) which is intended to reduce the complexity and costs to test goodwill for impairment. The amendment allows an entity the option to make a qualitative evaluation about the likelihood of goodwill impairment to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. An entity will no longer be required to calculate the fair value of a reporting unit unless the entity determines, based on its qualitative assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying amount. The ASU also expands upon the examples of events and circumstances that an entity should consider between annual impairment tests in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The amendment became effective for annual and interim goodwill impairment tests performed for the Company’s fiscal year beginning August 1, 2012. The Company does not expect the adoption of ASU 2011-08 to have a material impact on its consolidated financial statements.

In July 2011, the FASB issued ASU No. 2011-07 “Health Care Entities (Topic 954) - Presentation and Disclosure of Patient Service Revenue, Provision for Bad Debts, and the Allowance for Doubtful Accounts for Certain Health Care Entities”. This update was issued to provide greater transparency relating to accounting practices used for net patient service revenue and related bad debt allowances by health care entities. Some health care entities recognize patient service revenue at the time the services are rendered regardless of whether the entity expects to collect that amount or has assessed the patient’s ability to pay. These prior accounting practices used by some health care entities resulted in a gross-up of patient service revenue and the provision for bad debts, causing difficulty for users of financial statements to make accurate comparisons and analyses of financial statements among entities. ASU No. 2011-07 requires certain healthcare entities to change the presentation of the statement of operations, reclassifying the provision for bad debts associated with patient service revenue from an operating expense to a deduction from patient service revenue and also requires enhanced quantitative and qualitative disclosures relevant to the entity’s policies for recognizing revenue and assessing bad debts.

This update is not designed to change and will not change the net income reported by healthcare entities. The Company adopted this update in its first quarter of fiscal year 2013 with no impact on its consolidated financial position or results of operations.
