Accounting Policies [Abstract] | |||||||||||||||||||||||||
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block] | Note 1 - Summary of significant accounting policies | ||||||||||||||||||||||||
Nature of business | |||||||||||||||||||||||||
Enzo Biochem, Inc. (the “Company”) is an integrated life science and biotechnology company engaged in research, development, manufacturing and marketing of diagnostic and research products based on genetic engineering, biotechnology and molecular biology. These products are designed for the diagnosis of and/or screening for infectious diseases, cancers, genetic defects and other medically pertinent diagnostic information and are distributed in the United States and internationally. The Company is conducting research and development activities in the development of therapeutic products based on the Company’s technology platform of genetic modulation and immune modulation. The Company also operates a clinical laboratory that offers and provides diagnostic medical testing services in the New York, New Jersey and Eastern Pennsylvania medical communities. The Company operates in three segments (see Note 15). | |||||||||||||||||||||||||
Principles of consolidation | |||||||||||||||||||||||||
The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) and include the accounts of the Company and its wholly-owned subsidiaries, Enzo Clinical Labs, Inc., Enzo Life Sciences, Inc. (and its wholly-owned foreign subsidiaries), Enzo Therapeutics, Inc. and Enzo Realty LLC (“Realty”). All intercompany transactions and balances have been eliminated. The results of operations for companies acquired are included in the consolidated financial statements from the effective date of the acquisition. | |||||||||||||||||||||||||
Use of Estimates | |||||||||||||||||||||||||
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying footnotes. Actual results could differ from those estimates. | |||||||||||||||||||||||||
Foreign Currency Translation/Transactions | |||||||||||||||||||||||||
The Company has determined that the functional currency for its foreign subsidiaries is the local currency. For financial reporting purposes, assets and liabilities denominated in foreign currencies are translated at current exchange rates and profit and loss accounts are translated at weighted average exchange rates. Resulting translation gains and losses are included as a separate component of stockholders’ equity as accumulated other comprehensive income or loss. Gains or losses resulting from transactions entered into in other than the functional currency are recorded as foreign exchange gains and losses in the consolidated statements of operations. | |||||||||||||||||||||||||
Cash and cash equivalents | |||||||||||||||||||||||||
Cash and cash equivalents consist of demand deposits with banks, highly liquid money market funds, and highly liquid U.S. Government instruments acquired with maturities of less than ninety days. At July 31, 2013 and 2012, the Company had cash and cash equivalents in foreign bank accounts of $1.5 million and $2.5 million, respectively. | |||||||||||||||||||||||||
Fair Values of Financial Instruments | |||||||||||||||||||||||||
The recorded amounts of the Company’s cash and equivalents, receivables, loan payable, accounts payable and accrued liabilities approximate their fair values principally because of the short-term nature of these items. | |||||||||||||||||||||||||
Concentration of credit risk | |||||||||||||||||||||||||
Financial instruments that potentially subject the Company to concentrations of credit risk primarily consist of cash and cash equivalents and accounts receivable. | |||||||||||||||||||||||||
The Company believes the fair value of the aforementioned financial instruments approximates the cost due to the immediate or short-term nature of these items. | |||||||||||||||||||||||||
Concentration of credit risk with respect to the Company’s Life Sciences segment is mitigated by the diversity of the Company’s clients and their dispersion across many different geographic regions. To reduce risk, the Company routinely assesses the financial strength of these customers and, consequently, believes that its accounts receivable credit exposure with respect to these customers is limited. | |||||||||||||||||||||||||
The Company believes that the concentration of credit risk with respect to the Clinical Labs accounts receivable is mitigated by the diversity of its third party payers that insure individuals. To reduce risk, the Company routinely assesses the financial strength of these payers and, consequently, believes that its accounts receivable credit risk exposure, with respect to these payers, is limited. While the Company also has receivables due from the Federal Medicare program, the Company does not believe that these receivables represent a credit risk since the Medicare program is funded by the federal government and payment is primarily dependent on our submitting the appropriate documentation. | |||||||||||||||||||||||||
Accrual for Self-Funded Medical | |||||||||||||||||||||||||
Accruals for self-funded medical insurance are determined based on a number of assumptions and factors, including historical payment trends, claims history and current estimates. These estimated liabilities are not discounted. If actual trends differ from these estimates, the financial results could be impacted. | |||||||||||||||||||||||||
Revenue Recognition - Product revenues | |||||||||||||||||||||||||
Revenues from product sales are recognized when the products are shipped and title transfers, the sales price is fixed or determinable and collectability is reasonably assured. | |||||||||||||||||||||||||
Royalties | |||||||||||||||||||||||||
Royalty revenues are recorded in the period earned. Royalties received in advance of being earned are recorded as deferred revenues in the accompanying balance sheet. | |||||||||||||||||||||||||
Clinical laboratory services | |||||||||||||||||||||||||
Revenues from the Clinical Labs segment are recognized upon completion of the testing process for a specific patient and reported to the ordering physician. These revenues and the associated accounts receivable are based on gross amounts billed or billable for services rendered, net of a contractual adjustment, which is the difference between amounts billed to payers and the expected reimbursable settlements from such payers. | |||||||||||||||||||||||||
The following table summarizes the Clinical Lab segment’s net revenues and revenue percentages by revenue category: | |||||||||||||||||||||||||
Years ended July 31, | |||||||||||||||||||||||||
2013 | 2012 | 2011 | |||||||||||||||||||||||
Revenue category | (in %) | (in %) | (in %) | ||||||||||||||||||||||

Third-party payers | 26,014 | 47 | 29,616 | 50 | 24,335 | 46 | |||||||||||||||||||
Patient self-pay | 12,172 | 22 | 11,895 | 20 | 11,554 | 22 | |||||||||||||||||||
HMO’s | 5,206 | 9 | 5,234 | 9 | 5,017 | 10 | |||||||||||||||||||
Total | $ | 55,889 | 100 | % | $ | 59,403 | 100 | % | $ | 52,762 | 100 | % | |||||||||||||
The Company provides services to certain patients covered by various third-party payers, including the Federal Medicare program. Laws and regulations governing Medicare are complex and subject to interpretation for which action for noncompliance includes fines, penalties and exclusion from the Medicare programs (See Note 14). | |||||||||||||||||||||||||
Other than the Medicare program, one provider whose programs are included in the “Third-party payers” and “Health Maintenance Organizations” (“HMO’s”) categories represent approximately 22%, 21% and 22% of the Clinical Labs segment net revenue for the years ended July 31, 2013, 2012 and 2011 respectively. Another third party provider represents 9%,13% and 11% of the Clinical Labs segment’s net revenue for the years ended July 31, 2013, 2012 and 2011, respectively. | |||||||||||||||||||||||||
Contractual Adjustment | |||||||||||||||||||||||||
The Company’s estimate of contractual adjustment is based on significant assumptions and judgments, such as its interpretation of payer reimbursement policies, and bears the risk of change. The estimation process is based on the experience of amounts approved as reimbursable and ultimately settled by payers, versus the corresponding gross amount billed to the respective payers. The contractual adjustment is an estimate that reduces gross revenue based on gross billing rates, to amounts expected to be approved and reimbursed. Gross billings are based on a standard fee schedule the Company sets for all third-party payers, including Medicare, HMO’s and managed care providers. The Company adjusts the contractual adjustment estimate quarterly, based on its evaluation of current and historical settlement experience with payers, industry reimbursement trends, and other relevant factors which include the monthly and quarterly review of: 1) current gross billings and receivables and reimbursement by payer, 2) current changes in third party arrangements and 3) the growth of in-network provider arrangements and managed care plans specific to our Company. | |||||||||||||||||||||||||
During the years ended July 31, 2013, 2012 and 2011, the contractual adjustment percentages, determined using current and historical reimbursement statistics, were approximately 85%, 85% and 84%, respectively, of gross billings. | |||||||||||||||||||||||||
Accounts Receivable and Allowance for Doubtful Accounts | |||||||||||||||||||||||||
Accounts receivable are reported at realizable value, net of allowances for doubtful accounts, which is estimated and recorded in the period of the related revenue. | |||||||||||||||||||||||||
For the Clinical Labs segment, the allowance for doubtful accounts represents amounts that the Company does not expect to collect after the Company has exhausted its collection procedures. The Company estimates its allowance for doubtful accounts in the period the related services are billed and adjusts the estimate in future accounting periods as necessary. It bases the estimate for the allowance on the evaluation of historical collection experience, the aging profile of accounts receivable, payer mix and other relevant factors. | |||||||||||||||||||||||||
During the years ended July 31, 2013 and 2012, the Company determined an allowance for doubtful accounts for customers whose accounts receivable have been outstanding less than 210 days and either fully reserved or wrote off 100% of accounts receivable over 210 days, as it determined based on historical trends that those accounts were uncollectible, except for certain fully reserved balances, principally related to Medicare. These accounts have not been written off because the payer’s filing date deadline has not occurred or the collection process has not been exhausted. The Company adjusts the historical collection analysis for recoveries, if any, on an ongoing basis. | |||||||||||||||||||||||||
The Company’s ability to collect outstanding receivables from third-party payers is critical to its operating performance and cash flows. The primary collection risk lies with uninsured patients or patients for whom primary insurance has paid but a patient portion remains outstanding. The Company also assesses the current state of its billing functions in order to identify any known collection issues and to assess the impact, if any, on the allowance estimates which involves judgment. The Company believes that the collectability of its receivables is directly linked to the quality of its billing processes, most notably, those related to obtaining the correct information in order to bill effectively for the services provided. Should circumstances change (e.g. shift in payer mix, decline in economic conditions or deterioration in aging of receivables), our estimates of net realizable value of receivables could be reduced by a material amount. | |||||||||||||||||||||||||
The Clinical Labs segment’s net receivables are detailed by billing category and as a percent to its total net receivables. At July 31, 2013 and 2012, approximately 60% and 55%, respectively, of the Company’s net accounts receivable relates to its Clinical Labs business, which operates in the New York, New Jersey, and Eastern Pennsylvania medical communities. | |||||||||||||||||||||||||
The Life Sciences segment’s accounts receivable includes royalties receivable of $1.2 million and $1.7 million, as of July 31, 2013 and 2012, respectively, due from QIAGEN Gaithersburg Inc. (“Qiagen”) (see Note 12). | |||||||||||||||||||||||||

Ending balance | $ | 2,707 | $ | 3,273 | |||||||||||||||||||||
Inventories | |||||||||||||||||||||||||
The Company values inventory at the lower of cost (first-in, first-out) or market. Work-in-process and finished goods inventories consist of material, labor, and manufacturing overhead. Write downs of inventories to market value are based on a review of inventory quantities on hand and estimated sales forecasts based on sales history and anticipated future demand. Unanticipated changes in demand could have a significant impact on the value of our inventory and require additional write downs of inventory which would impact our results of operations. | |||||||||||||||||||||||||
Property, plant and equipment | |||||||||||||||||||||||||
Property, plant and equipment is stated at cost, and depreciated on the straight-line basis over the estimated useful lives of the various asset classes as follows: building and building improvements: 15-30 years, and laboratory machinery and equipment and office furniture and computer equipment which range from 3-10 years. Leasehold improvements are amortized over the term of the related leases or estimated useful lives of the assets, whichever is shorter. | |||||||||||||||||||||||||
Impairment of Long-Lived Assets | |||||||||||||||||||||||||
The Company reviews the recoverability of the carrying value of long-lived assets (including intangible assets with finite lives) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. Should indicators of impairment exist, the carrying values of the assets are evaluated in relation to the operating performance and future undiscounted cash flows of the underlying business. The net book value of an asset is adjusted to fair value if its expected future undiscounted cash flow is less than its book value. The Company reviewed long-lived assets for impairment at July 31, 2013. This test did not result in any impairment of long-lived assets. There were 0 impairments in 2012 or 2011, exclusive of Goodwill and Indefinite-lived intangibles in 2012. | |||||||||||||||||||||||||
Goodwill and Indefinite-Lived Intangibles | |||||||||||||||||||||||||
Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. The Company tests goodwill and had tested other indefinite lived intangibles for impairment annually as of the first day of the fourth quarter, or more frequently if indicators of potential impairment exist. Goodwill is reviewed for impairment utilizing a two-step process. The first step of the impairment test requires the identification of the reporting units and comparison of the fair value of each of these reporting units to their respective carrying value. If the carrying value of the reporting unit is less than its fair value, no impairment exists and the second step is not performed. If the carrying value of the reporting unit is higher than its fair value, the second step must be performed to compute the amount of the goodwill impairment, if any. In the second step, the impairment is computed by comparing the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized for the excess. | |||||||||||||||||||||||||
Intangible Assets | |||||||||||||||||||||||||
Intangible assets (exclusive of patents), arose primarily from acquisitions, and primarily consist of customer relationships, trademarks, licenses, and website and database content. Finite-lived intangible assets are amortized according to their estimated useful lives, which range from 4 to 15 years. | |||||||||||||||||||||||||
The Company has capitalized certain legal costs directly incurred in pursuing patent applications as patent costs. When such applications result in an issued patent, the related costs are amortized over a ten year period or the life of the patent, whichever is shorter, using the straight-line method. The Company reviews its issued patents and pending patent applications, and if it determines to abandon a patent application or that an issued patent no longer has economic value, the unamortized balance in deferred patent costs relating to that patent is immediately expensed. | |||||||||||||||||||||||||
Comprehensive loss | |||||||||||||||||||||||||
Comprehensive loss consists of net loss and foreign currency translation adjustments. Foreign currency translation adjustments included in comprehensive loss were not tax effected as investments in international affiliates are deemed to be permanent. Accumulated other comprehensive income is a separate component of stockholders’ equity and consists of foreign currency translation adjustments. | |||||||||||||||||||||||||
Shipping and Handling Costs | |||||||||||||||||||||||||
Shipping and handling costs associated with the distribution of finished goods to customers are recorded in cost of goods sold. | |||||||||||||||||||||||||
Research and Development | |||||||||||||||||||||||||
Research and development costs are charged to expense as incurred. | |||||||||||||||||||||||||
Advertising | |||||||||||||||||||||||||
All costs associated with advertising are expensed as incurred. Advertising expense, included in Selling, general and administrative expense, approximated $302, $237 and $235 for the years ended July 31, 2013, 2012 and 2011, respectively. | |||||||||||||||||||||||||
Income Taxes | |||||||||||||||||||||||||
The Company accounts for income taxes under the liability method of accounting for income taxes. Under the liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. The liability method requires that any tax benefits recognized for net operating loss carry forwards and other items be reduced by a valuation allowance when it is more likely than not that the benefits may not be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under the liability method, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. | |||||||||||||||||||||||||
It is the Company’s policy to provide for uncertain tax positions and the related interest and penalties based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. At July 31, 2013, the Company believes it has appropriately accounted for any unrecognized tax benefits. To the extent the Company prevails in matters for which a liability for an unrecognized tax benefit is established or is required to pay amounts in excess of the liability, the Company’s effective tax rate in a given financial statement period may be affected. | |||||||||||||||||||||||||
Segment Reporting | |||||||||||||||||||||||||
The Company follows accounting pronouncements which establish standards for reporting information on operating segments in interim and annual financial statements. An enterprise is required to separately report information about each operating segment that engages in business activities from which the segment may earn revenues and incur expenses, whose separate operating results are regularly reviewed by the chief operating decision maker regarding allocation of resources and performance assessment and which exceed specific quantitative thresholds related to revenue and profit or loss. The Company’s operating activities are reported in three segments (see Note 15). | |||||||||||||||||||||||||
Net income (loss) per share | |||||||||||||||||||||||||
Basic net income (loss) per share represents net income (loss) divided by the weighted average number of common shares outstanding during the period. The dilutive effect of potential common shares, consisting of outstanding stock options and unvested restricted stock, is determined using the treasury stock method. Diluted weighted average shares outstanding for fiscal 2013, 2012 and 2011 do not include the potential common shares from stock options and unvested restricted stock because to do so would have been antidilutive and as such is the same as basic weighted average shares outstanding. The number of potential common shares (“in the money options”) and unvested restricted stock excluded from the calculation of diluted earnings per share for the years ended July 31, 2013, 2012, and 2011 was 32,000, 0, and 27,000, respectively. | |||||||||||||||||||||||||
For the years ended July 31, 2013, 2012 and 2011, the effect of approximately 727,000, 736,000 and 785,000 respectively, of outstanding “out of the money” options to purchase common shares were excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive.

The Company records compensation expense associated with stock options and restricted stock based upon the fair value of stock based awards as measured at the grant date. The expense is recorded by amortizing the fair values on a straight line basis over the vesting period, adjusted for estimated forfeitures. | |||||||||||||||||||||||||
For the years ended July 31, 2013, 2012 and 2011, share-based compensation expense relating to the fair value of stock options, restricted shares and restricted stock units was approximately $545, $719, and $1,049, respectively (see Note 10). 0 excess tax benefits were recognized for the year ended July 31, 2013, 2012 and 2011. | |||||||||||||||||||||||||

Effect of new accounting pronouncements | |||||||||||||||||||||||||
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 adopted ASU 2011-08 in the first quarter of fiscal year 2013 and the adoption did not 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. | |||||||||||||||||||||||||
In July 2012, the FASB issued ASU 2012-02, “Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment” (ASU 2012-02), which permits an entity to make a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit’s indefinite-lived intangible asset is less than the asset’s carrying value before applying the two-step goodwill impairment model that is currently in place. If it is determined through the qualitative assessment that the fair value of a reporting unit’s indefinite-lived intangible asset is more likely than not greater than the asset’s carrying value, the remaining impairment steps would be unnecessary. The qualitative assessment is optional, allowing companies to go directly to the quantitative assessment. ASU 2012-02 is effective for the Company for annual and interim indefinite-lived intangible asset impairment tests performed beginning August 1, 2013, however early adoption is permitted. As the Company has 0 indefinite-lived intangibles, ASU 2012-02 is expected to have no impact on its consolidated financial statements. |

Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. The Company tests goodwill and had tested other indefinite-lived intangibles for impairment annually as of the first day of the fourth quarter, or more frequently if indicators of potential impairment exist. Goodwill is reviewed for impairment utilizing a two-step process. The first step of the impairment test requires the identification of the reporting units and comparison of the fair value of each of these reporting units to their respective carrying value. If the carrying value of the reporting unit is less than its fair value, no impairment exists and the second step is not performed. If the carrying value of the reporting unit is higher than its fair value, the second step must be performed to compute the amount of the goodwill impairment, if any. In the second step, the impairment is computed by comparing the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized for the excess. | |||||||||||||||||||||||||
The Company estimates the fair value of a reporting unit using a forward-looking discounted cash flow methodology. The assumptions included in the discounted cash flow methodology included among others; forecasted revenues based on historical and recent revenue trends, gross profit margins, operating income margins, working capital cash flow, perpetual growth rates, and long-term discount rates, all of which require significant judgments by management. As of the first day of the fourth quarter of 2013, the annual assessment date, the Company’s test did not indicate impairment at the Clinical Lab’s reporting unit. | |||||||||||||||||||||||||
As a result of decline in the Company’s market capitalization, relating to the decline in the Company’s stock price of 44% from May 1 to July 31, 2012, declining results in the fiscal 2012 fourth quarter and results from the completion of the refocusing of the Enzo Life Sciences reporting unit, the Company determined that these impairment factors required the completion of an interim impairment test as of July 31, 2012. Based upon the results of the interim impairment test as of July 31, 2012, the carrying value of the Enzo Life Sciences reporting unit was determined to be higher than its fair value and, accordingly, the Company performed a step two impairment analysis. The results of the step-two impairment analysis for the Enzo life Sciences reporting unit indicated that goodwill was fully impaired. As a result of the analysis the Company recognized a total non-cash impairment charge of $18.8 million ($18.0 net of related taxes) as of July 31, 2012. The impairment charge did not impact the Company’s consolidated cash flows, liquidity, and capital resources. The fair value of the Enzo Clinical Lab reporting unit was higher than its carrying value and therefore a step-two analysis was not required. | |||||||||||||||||||||||||

In connection with the annual assessment of indefinite-lived intangibles as of May 1, 2012, the Company determined the estimated fair value of trademarks, relating to the Enzo Life Science reporting unit, were less than their carrying values by $5.7 million primarily due to declines in projected revenues and in connection with future plans resulting from a strategic review. As a result of this impairment, which included a change in the future branding strategy, the useful life of the trademarks were reassessed and determined to have an estimated economic life of 5 years. A non-cash impairment charge of $5.7 million, ($4.4 million net of related taxes) was recorded for the trademark impairment in the fourth quarter of fiscal 2012. As a result of the reclassification of trademarks from indefinite lived to a 5 year life, annual amortization of trademarks is estimated to be $0.6 million per year. 0 impairment was determined to exist at May 1, 2013. | |||||||||||||||||||||||||
The aggregate goodwill and indefinite lived-intangible impairment charge recorded in the fiscal 2012 fourth quarter was $24.5 million, ($22.4 million net of related taxes). These charges did not affect consolidated cash flows, current liquidity or capital resources. |

The Company recorded a valuation allowance during the year ended July 31, 2013 and 2012 equal to domestic and certain foreign net deferred tax assets. The Company believes that the valuation allowance is necessary as it is not more likely than not that the deferred tax assets will be realized in the foreseeable future based on positive and negative evidence available at this time. This conclusion was reached because of uncertainties relating to future taxable income, in terms of both its timing and its sufficiency, which would enable the Company to realize the deferred tax assets. | |||||||||||||
As of July 31, 2013, the Company had U.S. federal net operating loss carryforwards of approximately $102.5 million. The U.S. federal tax loss carryforwards, if not fully utilized, expire between 2018 and 2033. Utilization is dependent on generating sufficient taxable income prior to expiration of the tax loss carryforwards. In addition, the Company has research and development tax credit carryforwards of approximately $0.9 million which expire between 2025 and 2033. As of July 31, 2013, the Company had foreign loss carryforwards of approximately $3.7 million. | |||||||||||||
As a result of certain acquisitions approximately $0.7 million of the Company’s U.S. federal net operating loss carryforwards are subject to an annual limitation under Internal Revenue Code Section 382 due to the ownership change. However, management does not believe that such a change would have a significant impact on the Company’s ability to utilize its tax loss carryforwards.

The Company, as plaintiff, is currently engaged in litigation in the United States District Court for the Southern District of New York against six parties (and certain of their related companies): Amersham plc, Perkin Elmer, Inc., Molecular Probes, Inc., Orchid Biosciences, Inc., Affymetrix, Inc., and Roche Diagnostic GmbH (“Roche”). These cases were commenced at various times from October 2002 to June 2004. In each of the six cases, the Company asserts similar (with some differences) causes of action against the defendants which can be generally described as contract, tort, fraud, and patent claims, except that no patent claims are asserted against Affymetrix. In the Roche case, Roche seeks a declaratory judgment of non-breach and patent invalidity against the Company. The cases were consolidated for pre-trial purposes in 2004 and there has been extensive discovery among the parties. In 2011, the defendants moved for summary judgment of non-infringement regarding the Company’s patent claims. In 2012, those motions were granted in part and denied in part. In December 2012, all six defendants moved for summary judgment on the Company’s non-patent claims. Additional discovery was taken and the Company responded to the motions in May 2013. Those motions are now fully briefed, but have not yet been decided. The Company expects that the pending motions will be decided by October 31, 2013. | |
On June 7, 2004, the Company and Enzo Life Sciences, Inc., filed suit in the United States District Court for the District of Connecticut against Applera Corporation and its wholly-owned subsidiary Tropix, Inc., now Life Technologies, Inc. (NASDAQ:LIFE). The complaint alleged infringement of six patents relating to DNA sequencing systems, labeled nucleotide products, and other technology. Yale University is the owner of four of the patents and the Company is the exclusive licensee. These four patents are commonly referred to as the “Ward” patents. On November 12, 2012, a jury in New Haven found that one of these patents (United States Patent No. 5,449,667) was infringed and not proven invalid. The jury awarded $48.5 million for this infringement. Prejudgment interest should provide for additional recovery in the tens of millions of dollars. | |
Life Technologies will likely appeal and there can be no assurance that the Company will be successful in this litigation. Even if the Company is not successful, management does not believe that there will be a significant adverse monetary impact on the Company. | |
In 2012, the Company received a Subpoena Duces Tecum (the “Subpoena”) from the federal Department of Health and Human Services, Office of Inspector General (“OIG”). The Subpoena was issued as part of an investigation being conducted by the US Attorney’s Office for the Eastern District of New York in conjunction with the OIG. While a number of potential issues were raised initially by the government, the investigation has come to focus primarily on certain practices relating to an alleged failure to collect diagnosis codes from physicians who ordered tests through Enzo Clinical Labs. The time period covered by the investigation is from 2004 through 2011. In response to the Subpoena, the Company is cooperating with the government and has provided documents as requested and no claim has yet been asserted by the OIG. The Company continues to review the methodologies around the matters raised as well as the facts that impact them. Due to the on-going review, various questions of fact and the continuing discussions with the government the Company is unable at this time to predict the outcome or estimate the potential impact that could result from the final resolution of the investigation. | |
The Company is party to other claims, legal actions, complaints, and contractual disputes that arise in the ordinary course of business. The Company believes that any liability that may ultimately result from the resolution of these matters will not, individually or in the aggregate, have a material adverse effect on its financial position or results of operations. |

Accounting Policies [Abstract] | |||||||||||||||||||||||||
Nature of Business [Policy Text Block] | Nature of business | ||||||||||||||||||||||||
Enzo Biochem, Inc. (the “Company”) is an integrated life science and biotechnology company engaged in research, development, manufacturing and marketing of diagnostic and research products based on genetic engineering, biotechnology and molecular biology. These products are designed for the diagnosis of and/or screening for infectious diseases, cancers, genetic defects and other medically pertinent diagnostic information and are distributed in the United States and internationally. The Company is conducting research and development activities in the development of therapeutic products based on the Company’s technology platform of genetic modulation and immune modulation. The Company also operates a clinical laboratory that offers and provides diagnostic medical testing services in the New York, New Jersey and Eastern Pennsylvania medical communities. The Company operates in three segments (see Note 15). | |||||||||||||||||||||||||
Consolidation, Policy [Policy Text Block] | Principles of consolidation | ||||||||||||||||||||||||
The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) and include the accounts of the Company and its wholly-owned subsidiaries, Enzo Clinical Labs, Inc., Enzo Life Sciences, Inc. (and its wholly-owned foreign subsidiaries), Enzo Therapeutics, Inc. and Enzo Realty LLC (“Realty”). All intercompany transactions and balances have been eliminated. The results of operations for companies acquired are included in the consolidated financial statements from the effective date of the acquisition. | |||||||||||||||||||||||||
Use of Estimates, Policy [Policy Text Block] | Use of Estimates | ||||||||||||||||||||||||
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying footnotes. Actual results could differ from those estimates. | |||||||||||||||||||||||||
Foreign Currency Transactions and Translations Policy [Policy Text Block] | Foreign Currency Translation/Transactions | ||||||||||||||||||||||||
The Company has determined that the functional currency for its foreign subsidiaries is the local currency. For financial reporting purposes, assets and liabilities denominated in foreign currencies are translated at current exchange rates and profit and loss accounts are translated at weighted average exchange rates. Resulting translation gains and losses are included as a separate component of stockholders’ equity as accumulated other comprehensive income or loss. Gains or losses resulting from transactions entered into in other than the functional currency are recorded as foreign exchange gains and losses in the consolidated statements of operations. | |||||||||||||||||||||||||
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash and cash equivalents | ||||||||||||||||||||||||
Cash and cash equivalents consist of demand deposits with banks, highly liquid money market funds, and highly liquid U.S. Government instruments acquired with maturities of less than ninety days. At July 31, 2013 and 2012, the Company had cash and cash equivalents in foreign bank accounts of $1.5 million and $2.5 million, respectively. | |||||||||||||||||||||||||
Fair Value of Financial Instruments, Policy [Policy Text Block] | Fair Values of Financial Instruments | ||||||||||||||||||||||||
The recorded amounts of the Company’s cash and equivalents, receivables, loan payable, accounts payable and accrued liabilities approximate their fair values principally because of the short-term nature of these items. | |||||||||||||||||||||||||
Concentration Risk, Credit Risk, Policy [Policy Text Block] | Concentration of credit risk | ||||||||||||||||||||||||
Financial instruments that potentially subject the Company to concentrations of credit risk primarily consist of cash and cash equivalents and accounts receivable. | |||||||||||||||||||||||||
The Company believes the fair value of the aforementioned financial instruments approximates the cost due to the immediate or short-term nature of these items. | |||||||||||||||||||||||||
Concentration of credit risk with respect to the Company’s Life Sciences segment is mitigated by the diversity of the Company’s clients and their dispersion across many different geographic regions. To reduce risk, the Company routinely assesses the financial strength of these customers and, consequently, believes that its accounts receivable credit exposure with respect to these customers is limited. | |||||||||||||||||||||||||
The Company believes that the concentration of credit risk with respect to the Clinical Labs accounts receivable is mitigated by the diversity of its third party payers that insure individuals. To reduce risk, the Company routinely assesses the financial strength of these payers and, consequently, believes that its accounts receivable credit risk exposure, with respect to these payers, is limited. While the Company also has receivables due from the Federal Medicare program, the Company does not believe that these receivables represent a credit risk since the Medicare program is funded by the federal government and payment is primarily dependent on our submitting the appropriate documentation. | |||||||||||||||||||||||||
Accrual For Self-Funded Medical [Policy Text Block] | Accrual for Self-Funded Medical | ||||||||||||||||||||||||
Accruals for self-funded medical insurance are determined based on a number of assumptions and factors, including historical payment trends, claims history and current estimates. These estimated liabilities are not discounted. If actual trends differ from these estimates, the financial results could be impacted. | |||||||||||||||||||||||||
Revenue Recognition, Policy [Policy Text Block] | Revenue Recognition - Product revenues | ||||||||||||||||||||||||
Revenues from product sales are recognized when the products are shipped and title transfers, the sales price is fixed or determinable and collectability is reasonably assured. | |||||||||||||||||||||||||
Revenue Recognition, Services, Royalty Fees [Policy Text Block] | Royalties | ||||||||||||||||||||||||
Royalty revenues are recorded in the period earned. Royalties received in advance of being earned are recorded as deferred revenues in the accompanying balance sheet. | |||||||||||||||||||||||||
Clinical Laboratory Services [Policy Text Block] | Clinical laboratory services | ||||||||||||||||||||||||
Revenues from the Clinical Labs segment are recognized upon completion of the testing process for a specific patient and reported to the ordering physician. These revenues and the associated accounts receivable are based on gross amounts billed or billable for services rendered, net of a contractual adjustment, which is the difference between amounts billed to payers and the expected reimbursable settlements from such payers. | |||||||||||||||||||||||||
The following table summarizes the Clinical Lab segment’s net revenues and revenue percentages by revenue category: | |||||||||||||||||||||||||
Years ended July 31, | |||||||||||||||||||||||||
2013 | 2012 | 2011 | |||||||||||||||||||||||
Revenue category | (in %) | (in %) | (in %) | ||||||||||||||||||||||

Third-party payers | 26,014 | 47 | 29,616 | 50 | 24,335 | 46 | |||||||||||||||||||
Patient self-pay | 12,172 | 22 | 11,895 | 20 | 11,554 | 22 | |||||||||||||||||||
HMO’s | 5,206 | 9 | 5,234 | 9 | 5,017 | 10 | |||||||||||||||||||
Total | $ | 55,889 | 100 | % | $ | 59,403 | 100 | % | $ | 52,762 | 100 | % | |||||||||||||
The Company provides services to certain patients covered by various third-party payers, including the Federal Medicare program. Laws and regulations governing Medicare are complex and subject to interpretation for which action for noncompliance includes fines, penalties and exclusion from the Medicare programs (See Note 14). | |||||||||||||||||||||||||
Other than the Medicare program, one provider whose programs are included in the “Third-party payers” and “Health Maintenance Organizations” (“HMO’s”) categories represent approximately 22%, 21% and 22% of the Clinical Labs segment net revenue for the years ended July 31, 2013, 2012 and 2011 respectively. Another third party provider represents 9%,13% and 11% of the Clinical Labs segment’s net revenue for the years ended July 31, 2013, 2012 and 2011, respectively. | |||||||||||||||||||||||||
Contractual Adjustments and Third Party Settlements, Policy [Policy Text Block] | Contractual Adjustment | ||||||||||||||||||||||||
The Company’s estimate of contractual adjustment is based on significant assumptions and judgments, such as its interpretation of payer reimbursement policies, and bears the risk of change. The estimation process is based on the experience of amounts approved as reimbursable and ultimately settled by payers, versus the corresponding gross amount billed to the respective payers. The contractual adjustment is an estimate that reduces gross revenue based on gross billing rates, to amounts expected to be approved and reimbursed. Gross billings are based on a standard fee schedule the Company sets for all third-party payers, including Medicare, HMO’s and managed care providers. The Company adjusts the contractual adjustment estimate quarterly, based on its evaluation of current and historical settlement experience with payers, industry reimbursement trends, and other relevant factors which include the monthly and quarterly review of: 1) current gross billings and receivables and reimbursement by payer, 2) current changes in third party arrangements and 3) the growth of in-network provider arrangements and managed care plans specific to our Company. | |||||||||||||||||||||||||
During the years ended July 31, 2013, 2012 and 2011, the contractual adjustment percentages, determined using current and historical reimbursement statistics, were approximately 85%, 85% and 84%, respectively, of gross billings. | |||||||||||||||||||||||||
Accounts Receivable And Allowance For Doubtful Accounts [Policy Text Block] | Accounts Receivable and Allowance for Doubtful Accounts | ||||||||||||||||||||||||
Accounts receivable are reported at realizable value, net of allowances for doubtful accounts, which is estimated and recorded in the period of the related revenue. | |||||||||||||||||||||||||
For the Clinical Labs segment, the allowance for doubtful accounts represents amounts that the Company does not expect to collect after the Company has exhausted its collection procedures. The Company estimates its allowance for doubtful accounts in the period the related services are billed and adjusts the estimate in future accounting periods as necessary. It bases the estimate for the allowance on the evaluation of historical collection experience, the aging profile of accounts receivable, payer mix and other relevant factors. | |||||||||||||||||||||||||
During the years ended July 31, 2013 and 2012, the Company determined an allowance for doubtful accounts for customers whose accounts receivable have been outstanding less than 210 days and either fully reserved or wrote off 100% of accounts receivable over 210 days, as it determined based on historical trends that those accounts were uncollectible, except for certain fully reserved balances, principally related to Medicare. These accounts have not been written off because the payer’s filing date deadline has not occurred or the collection process has not been exhausted. The Company adjusts the historical collection analysis for recoveries, if any, on an ongoing basis. | |||||||||||||||||||||||||
The Company’s ability to collect outstanding receivables from third-party payers is critical to its operating performance and cash flows. The primary collection risk lies with uninsured patients or patients for whom primary insurance has paid but a patient portion remains outstanding. The Company also assesses the current state of its billing functions in order to identify any known collection issues and to assess the impact, if any, on the allowance estimates which involves judgment. The Company believes that the collectability of its receivables is directly linked to the quality of its billing processes, most notably, those related to obtaining the correct information in order to bill effectively for the services provided. Should circumstances change (e.g. shift in payer mix, decline in economic conditions or deterioration in aging of receivables), our estimates of net realizable value of receivables could be reduced by a material amount. | |||||||||||||||||||||||||
The Clinical Labs segment’s net receivables are detailed by billing category and as a percent to its total net receivables. At July 31, 2013 and 2012, approximately 60% and 55%, respectively, of the Company’s net accounts receivable relates to its Clinical Labs business, which operates in the New York, New Jersey, and Eastern Pennsylvania medical communities. | |||||||||||||||||||||||||
The Life Sciences segment’s accounts receivable includes royalties receivable of $1.2 million and $1.7 million, as of July 31, 2013 and 2012, respectively, due from QIAGEN Gaithersburg Inc. (“Qiagen”) (see Note 12). | |||||||||||||||||||||||||
The following is a table of the Company’s net accounts receivable by segment. | |||||||||||||||||||||||||

Inventory, Policy [Policy Text Block] | Inventories | ||||||||||||||||||||||||
The Company values inventory at the lower of cost (first-in, first-out) or market. Work-in-process and finished goods inventories consist of material, labor, and manufacturing overhead. Write downs of inventories to market value are based on a review of inventory quantities on hand and estimated sales forecasts based on sales history and anticipated future demand. Unanticipated changes in demand could have a significant impact on the value of our inventory and require additional write downs of inventory which would impact our results of operations. | |||||||||||||||||||||||||
Property, Plant and Equipment, Policy [Policy Text Block] | Property, plant and equipment | ||||||||||||||||||||||||
Property, plant and equipment is stated at cost, and depreciated on the straight-line basis over the estimated useful lives of the various asset classes as follows: building and building improvements: 15-30 years, and laboratory machinery and equipment and office furniture and computer equipment which range from 3-10 years. Leasehold improvements are amortized over the term of the related leases or estimated useful lives of the assets, whichever is shorter. | |||||||||||||||||||||||||
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | Impairment of Long-Lived Assets | ||||||||||||||||||||||||
The Company reviews the recoverability of the carrying value of long-lived assets (including intangible assets with finite lives) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. Should indicators of impairment exist, the carrying values of the assets are evaluated in relation to the operating performance and future undiscounted cash flows of the underlying business. The net book value of an asset is adjusted to fair value if its expected future undiscounted cash flow is less than its book value. The Company reviewed long-lived assets for impairment at July 31, 2013. This test did not result in any impairment of long-lived assets. There were 0 impairments in 2012 or 2011, exclusive of Goodwill and Indefinite-lived intangibles in 2012. | |||||||||||||||||||||||||
Goodwill and Intangible Assets, Intangible Assets, Indefinite-Lived, Policy [Policy Text Block] | Goodwill and Indefinite-Lived Intangibles | ||||||||||||||||||||||||
Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. The Company tests goodwill and had tested other indefinite lived intangibles for impairment annually as of the first day of the fourth quarter, or more frequently if indicators of potential impairment exist. Goodwill is reviewed for impairment utilizing a two-step process. The first step of the impairment test requires the identification of the reporting units and comparison of the fair value of each of these reporting units to their respective carrying value. If the carrying value of the reporting unit is less than its fair value, no impairment exists and the second step is not performed. If the carrying value of the reporting unit is higher than its fair value, the second step must be performed to compute the amount of the goodwill impairment, if any. In the second step, the impairment is computed by comparing the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized for the excess. | |||||||||||||||||||||||||
Intangible Assets, Finite-Lived, Policy [Policy Text Block] | Intangible Assets | ||||||||||||||||||||||||
Intangible assets (exclusive of patents), arose primarily from acquisitions, and primarily consist of customer relationships, trademarks, licenses, and website and database content. Finite-lived intangible assets are amortized according to their estimated useful lives, which range from 4 to 15 years. | |||||||||||||||||||||||||
The Company has capitalized certain legal costs directly incurred in pursuing patent applications as patent costs. When such applications result in an issued patent, the related costs are amortized over a ten year period or the life of the patent, whichever is shorter, using the straight-line method. The Company reviews its issued patents and pending patent applications, and if it determines to abandon a patent application or that an issued patent no longer has economic value, the unamortized balance in deferred patent costs relating to that patent is immediately expensed. | |||||||||||||||||||||||||
Comprehensive Loss [Policy Text Block] | Comprehensive loss | ||||||||||||||||||||||||
Comprehensive loss consists of net loss and foreign currency translation adjustments. Foreign currency translation adjustments included in comprehensive loss were not tax effected as investments in international affiliates are deemed to be permanent. Accumulated other comprehensive income is a separate component of stockholders’ equity and consists of foreign currency translation adjustments. | |||||||||||||||||||||||||
Shipping and Handling Cost, Policy [Policy Text Block] | Shipping and Handling Costs | ||||||||||||||||||||||||
Shipping and handling costs associated with the distribution of finished goods to customers are recorded in cost of goods sold. | |||||||||||||||||||||||||
Research and Development Expense, Policy [Policy Text Block] | Research and Development | ||||||||||||||||||||||||
Research and development costs are charged to expense as incurred. | |||||||||||||||||||||||||
Advertising Costs, Policy [Policy Text Block] | Advertising | ||||||||||||||||||||||||
All costs associated with advertising are expensed as incurred. Advertising expense, included in Selling, general and administrative expense, approximated $302, $237 and $235 for the years ended July 31, 2013, 2012 and 2011, respectively. | |||||||||||||||||||||||||
Income Tax, Policy [Policy Text Block] | Income Taxes | ||||||||||||||||||||||||
The Company accounts for income taxes under the liability method of accounting for income taxes. Under the liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. The liability method requires that any tax benefits recognized for net operating loss carry forwards and other items be reduced by a valuation allowance when it is more likely than not that the benefits may not be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under the liability method, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. | |||||||||||||||||||||||||
It is the Company’s policy to provide for uncertain tax positions and the related interest and penalties based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. At July 31, 2013, the Company believes it has appropriately accounted for any unrecognized tax benefits. To the extent the Company prevails in matters for which a liability for an unrecognized tax benefit is established or is required to pay amounts in excess of the liability, the Company’s effective tax rate in a given financial statement period may be affected. | |||||||||||||||||||||||||
Segment Reporting, Policy [Policy Text Block] | Segment Reporting | ||||||||||||||||||||||||
The Company follows accounting pronouncements which establish standards for reporting information on operating segments in interim and annual financial statements. An enterprise is required to separately report information about each operating segment that engages in business activities from which the segment may earn revenues and incur expenses, whose separate operating results are regularly reviewed by the chief operating decision maker regarding allocation of resources and performance assessment and which exceed specific quantitative thresholds related to revenue and profit or loss. The Company’s operating activities are reported in three segments (see Note 15). | |||||||||||||||||||||||||
Earnings Per Share, Policy [Policy Text Block] | Net income (loss) per share | ||||||||||||||||||||||||
Basic net income (loss) per share represents net income (loss) divided by the weighted average number of common shares outstanding during the period. The dilutive effect of potential common shares, consisting of outstanding stock options and unvested restricted stock, is determined using the treasury stock method. Diluted weighted average shares outstanding for fiscal 2013, 2012 and 2011 do not include the potential common shares from stock options and unvested restricted stock because to do so would have been antidilutive and as such is the same as basic weighted average shares outstanding. The number of potential common shares (“in the money options”) and unvested restricted stock excluded from the calculation of diluted earnings per share for the years ended July 31, 2013, 2012, and 2011 was 32,000, 0, and 27,000, respectively. | |||||||||||||||||||||||||
For the years ended July 31, 2013, 2012 and 2011, the effect of approximately 727,000, 736,000 and 785,000 respectively, of outstanding “out of the money” options to purchase common shares were excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] | Share-Based Compensation | ||||||||||||||||||||||||
The Company records compensation expense associated with stock options and restricted stock based upon the fair value of stock based awards as measured at the grant date. The expense is recorded by amortizing the fair values on a straight line basis over the vesting period, adjusted for estimated forfeitures. | |||||||||||||||||||||||||
For the years ended July 31, 2013, 2012 and 2011, share-based compensation expense relating to the fair value of stock options, restricted shares and restricted stock units was approximately $545, $719, and $1,049, respectively (see Note 10). 0 excess tax benefits were recognized for the year ended July 31, 2013, 2012 and 2011. | |||||||||||||||||||||||||

As of July 31, 2013, there was $531 of total unrecognized compensation cost related to nonvested share-based payment arrangements granted under the Company’s incentive stock plans, which will be recognized over a weighted average remaining life of approximately fifteen months. | |||||||||||||||||||||||||
New Accounting Pronouncements, Policy [Policy Text Block] | Effect of new accounting pronouncements | ||||||||||||||||||||||||
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 adopted ASU 2011-08 in the first quarter of fiscal year 2013 and the adoption did not 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. | |||||||||||||||||||||||||
In July 2012, the FASB issued ASU 2012-02, “Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment” (ASU 2012-02), which permits an entity to make a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit’s indefinite-lived intangible asset is less than the asset’s carrying value before applying the two-step goodwill impairment model that is currently in place. If it is determined through the qualitative assessment that the fair value of a reporting unit’s indefinite-lived intangible asset is more likely than not greater than the asset’s carrying value, the remaining impairment steps would be unnecessary. The qualitative assessment is optional, allowing companies to go directly to the quantitative assessment. ASU 2012-02 is effective for the Company for annual and interim indefinite-lived intangible asset impairment tests performed beginning August 1, 2013, however early adoption is permitted. As the Company has 0 indefinite-lived intangibles, ASU 2012-02 is expected to have no impact on its consolidated financial statements. |
