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 molecular and esoteric diagnostic medical testing services in the New York and New Jersey 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.

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 and highly liquid money market funds. At July 31, 2017 and 2016, the Company had cash and cash equivalents in foreign bank accounts of $0.5 million.

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 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]


Royalty revenues are recorded in the period earned. Royalties received in advance of being earned are recorded as deferred revenues.

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,
    2017     2016     2015  
Revenue category   Amount     %     Amount     %     Amount     %  
Third-party payers   $ 43,059       56     $ 34,454       49     $ 30,685       49  
Patient self-pay     11,380       15       14,744       21       11,028       17  
Medicare     12,705       16       11,392       16       11,981       19  
HMO’s     10,263       13       10,325       14       9,720       15  
Total   $ 77,407       100 %   $ 70,915       100 %   $ 63,414       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 39%, 30% and 28% of the Clinical Labs segment net revenue for the years ended July 31, 2017, 2016 and 2015 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, 2017, 2016 and 2015, the contractual adjustment percentages, determined using current and historical reimbursement statistics, were approximately 84%, 84% and 85%, 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 reduces the allowance in future accounting periods based on write-offs during those periods. It bases the estimate for the allowance on the evaluation of historical experience of accounts going to collections and the net amounts not received. Accounts going to collection include the balances, after receipt of the approved settlements from third party payers, for the insufficient diagnosis information received from the ordering physician which results in denials of payment, and our estimate of the uncollected portion of receivables from self-payers, including deductibles and copayments, which are subject to credit risk and patients’ ability to pay. The Company fully reserves through its contractual allowances amounts that 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 on-going 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 allowance for doubtful accounts as a percentage of total accounts receivable at July 31, 2017 and 2016 was 19.1% and 19.4% respectively.

The Clinical Labs segment’s net receivables are detailed by billing category and as a percent to its total net receivables. At July 31, 2017 and 2016, approximately 75% and 71%, respectively, of the Company’s net accounts receivable relates to its Clinical Labs business, which operates in the New York and New Jersey medical communities.

The Life Sciences segment’s accounts receivable includes royalties receivable of $0.4 million and $0.5 million, as of July 31, 2017 and 2016, respectively, due from QIAGEN Gaithersburg Inc. (“Qiagen”) (see Note 12).

The following is a table of the Company’s net accounts receivable by segment.

    July 31, 2017     July 31, 2016  
Net accounts receivable by segment   Amount     %     Amount     %  
Clinical Labs (by billing category)                                
Third party payers   $ 7,256       64     $ 5,861       57  
Patient self-pay     1,591       14       1,676       16  
Medicare     1,385       12       1,486       14  
HMO’s     1,169       10       1,341       13  
Total Clinical Labs     11,401       100 %     10,364       100 %
Total Life Sciences     3,779               4,228          
Total accounts receivable – net   $ 15,180             $ 14,592          

Changes in the Company’s allowance for doubtful accounts are as follows:

     July 31, 2017     July 31, 2016  
Beginning balance   $ 3,517     $ 1,786  
Provision for doubtful accounts     2,775       2,336  
Write-offs     (2,716 )     (605 )
Ending balance   $ 3,576     $ 3,517  
Inventory, Policy [Policy Text Block]


The Company values inventory at the lower of cost (first-in, first-out) or net realizable value, which approximates 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.

Goodwill and Intangible Assets, Policy [Policy Text Block]

Goodwill and Intangible Assets

Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired.

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. Indefinite-lived intangibles are not amortized and are evaluated each reporting period to determine whether events and circumstances continue to support their having an indefinite life. Indefinite-lived intangibles found to no longer have an indefinite life are evaluated for impairment and are then amortized over their remaining useful life as finite-lived intangible assets. Patents represent capitalized legal costs incurred in pursuing patent applications. When such applications result in an issued patent, the related capitalized 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.

Impairment or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [Policy Text Block]

Impairment testing for Goodwill and Long-Lived Assets

The Company tests goodwill annually as of the first day of the fourth quarter, or more frequently if indicators of potential impairment exist. In assessing goodwill for impairment, the Company has the option to first perform a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company is not required to perform any additional tests in assessing goodwill for impairment. However, if the Company concludes otherwise or elects not to perform the qualitative assessment, then it is required to perform the first step of a two-step quantitative impairment review process. The first step of the quantitative 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 amount. If the carrying amount of the reporting unit is less than its fair value, no impairment exists and the second step is not performed. If the carrying amount of the reporting unit is higher than its fair value, the second step must be performed to compute the amount of the goodwill impairment. In the second step, the impairment charge is the amount by which the carrying amount exceeds the reporting unit’s fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The Company performed a quantitative assessment in 2017 and a qualitative assessment in 2016 and 2015, and concluded there were no goodwill impairments.

The Company reviews the recoverability of the carrying value of long-lived assets (including intangible assets with finite lives) for impairment annually as of the first day of the fourth quarter, or more frequently if indicators of potential impairment exist. 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. There were no long-lived asset impairments in 2017, 2016 or 2015.

Comprehensive Loss [Policy Text Block]

Comprehensive income (loss)

Comprehensive income (loss) consists of the Company’s consolidated net income (loss) and foreign currency translation adjustments. Foreign currency translation adjustments included in comprehensive income (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 the cumulative 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]


All costs associated with advertising are expensed as incurred. Advertising expense, included in selling, general and administrative expense, approximated $649, $601 and $556 for the years ended July 31, 2017, 2016 and 2015, 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, 2017, 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 separately reports 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 2017 and 2015 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 for 2017 and 2015. For fiscal 2016, approximately 449,000 weighted average stock options were included in the calculation of diluted weighted average shares outstanding. The number of potential common shares (“in the money options”) and unvested restricted stock excluded from the calculation of diluted weighted average shares outstanding for the years ended July 31, 2017, and 2015 was 961,000, and 403,000, respectively.

For the years ended July 31, 2017, 2016 and 2015, the effect of approximately zero, 282,000 and 977,000 respectively, of outstanding “out of the money” options to purchase common shares were excluded from the calculation of diluted weighted average shares outstanding because their effect would be anti-dilutive. The following table sets forth the computation of basic and diluted net loss per share for the years ended July 31:

    2017     2016     2015  
Net (loss) income   $ (2,504 )   $ 45,286     $ (2,285 )
Weighted-average common shares outstanding - basic     46,350       46,153       45,355  
Add: effect of dilutive stock options and restricted stock           449        
Weighted-average common shares outstanding - diluted     46,350       46,602       45,355  
Net (loss) income per share – basic   $ (0.05 )   $ 0.98     $ (0.05 )
Net (loss) income per share – diluted   $ (0.05 )   $ 0.97     $ (0.05 )
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 Company determines the award values of stock options using the Black Scholes option pricing model.

The expense is recorded by amortizing the fair values on a straight-line basis over the vesting period, adjusted for forfeitures.

For the years ended July 31, 2017, 2016 and 2015, share-based compensation expense relating to the fair value of stock options, restricted shares and restricted stock units was approximately $831, $525, and $429, respectively (see Note 10). No excess tax benefits were recognized for the year ended July 31, 2016, 2015 and 2014.

The following table sets forth the amount of expense related to share-based payment arrangements included in specific line items in the accompanying statement of operations for the years ended July 31:

    2017     2016     2015  
Cost of clinical laboratory services   $ 6     $ 6     $ 5  
Research and development                 2  
Selling, general and administrative     825       519       422  
    $ 831     $ 525     $ 429  

As of July 31, 2017, there was $1,187 of total unrecognized compensation cost related to non-vested share-based payment arrangements granted under the Company’s incentive stock plans, which will be recognized over a weighted average remaining life of approximately seventeen months.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Adopted Accounting Pronouncements

In November 2015, the FASB issued ASU 2015-17, Income Taxes – Balance Sheet Classification of Deferred Taxes to simplify the presentation of deferred income taxes, the amendments in this ASU require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments in this update apply to all entities that present a classified statement of financial position. We adopted this standard in our fiscal year ending July 31, 2017. The adoption of this update had no impact on our consolidation financial statements.

In April 2015, the FASB issued ASU No. 2015-03 Interest – Imputation of Interest. The ASU was issued as part of the Simplification Initiatives, to simplify presentation of debt issuance costs. The amendments in the update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. We adopted this standard at the start of our fiscal year ending July 31, 2017. The adoption of this update had no material impact on our consolidated financial statements.

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory (Topic 330). ASU 2015-11 changes the measurement principle for inventory from the lower of cost or market to lower of cost or net realizable value. We adopted this standard in our fiscal year ending in July 31, 2017. The adoption of this update had no impact on our consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other – Simplifying the Test for Goodwill Impairment. The ASU eliminates step two in the current two-step process so that any goodwill impairment is measured as the amount by which the reporting unit’s carrying amount exceeds its fair value. We early adopted this standard in our fiscal year ending July 31, 2017. The adoption of this update had no material impact on our consolidated financial statements.

Pronouncements Issued But Not Yet Adopted Policy

Pronouncements Issued but Not Yet Adopted

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers: Topic 606. ASU 2014-09 and its amendments supersede the current revenue recognition guidance, including industry-specific guidance. The new standard introduces a five-step model to achieve its core principle of the entity recognizing revenue to depict the transfer of goods or services to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services, and on transfer of control, as opposed to transfer of risk and rewards. The standard also expands the required financial statement disclosures regarding revenue recognition. ASU 2014-09 will be effective for our interim periods and the fiscal year beginning August 1, 2018, and we do not expect to early adopt for reporting periods beginning after December 15, 2016. We expect to use retrospective application upon adoption. Based on our preliminary assessment, we expect the adoption of this ASU will result in the majority of the amounts that have historically been classified as bad debt expense, primarily related to patient responsibility, will be reflected as a reduction of the transaction price and therefore as a reduction in revenue; and increased disclosure, including qualitative and quantitative disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts from customers. However, the adoption of this ASU is not expected to have a material impact on our financial position or cash flows.

In February 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-02 – Leases (Topic 842). The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for our fiscal year beginning August 1, 2019 including interim periods within that fiscal year. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. We believe the adoption of this standard will materially impact our consolidated financial statements by significantly increasing our non-current assets and non-current liabilities on our consolidated balance sheets in order to record the right of use assets and related lease liabilities for our existing operating leases.

In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting,” which requires all excess tax benefits or deficiencies to be recognized as income tax expense or benefit in the income statement. In addition, excess tax benefits should be classified along with other income tax cash flows as an operating activity in the statement of cash flows. Application of the standard is required for our annual and interim periods beginning August 1, 2017. We do not expect the adoption of this new standard to have a material impact on our consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, “Compensation – Stock Compensation (Topic 708) Scope of Modification Accounting” which provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. Adoption of the Standard is required for our annual and interim periods beginning August 1, 2018 with the amendments in the update applied prospectively to an award modified on or after the adoption date. Early adoption is permitted. We are currently evaluating the impact this new standard will have on the consolidated financial statements.
