NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

As of January 31, 2011
and for the three and six months ended
January 31, 2011 and 2010
(Unaudited)
(in thousands, except share data)

Note 1 – Basis of Presentation

The accompanying consolidated financial statements include the accounts of Enzo Biochem, Inc. and its wholly-owned subsidiaries, Enzo Life Sciences, Enzo Clinical Labs, Enzo Therapeutics and Enzo Realty LLC, collectively referred to as the “Company” or “Companies”. The consolidated balance sheet as of January 31, 2011, the consolidated statement of stockholders’ equity and comprehensive (loss) income for the six months ended January 31, 2011, the consolidated statements of cash flows for the six months ended January 31, 2011 and 2010, and the consolidated statements of operations for the three and six months ended January 31, 2011 and 2010, are unaudited. In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position and operating results for the interim periods have been made. Certain information and footnote disclosure, normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States, have been condensed or omitted. The consolidated financial statements should be read in conjunction with the consolidated financial statements for the year ended July 31, 2010 and notes thereto contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission. The consolidated balance sheet at July 31, 2010 has been derived from the audited financial statements at that date. The results of operations for the three and six months ended January 31, 2011 are not necessarily indicative of the results that may be expected for the fiscal year ending July 31, 2011.

Recent Accounting Pronouncements

In October 2009, the FASB issued a Consensus of the FASB Emerging Issues Task Force relating to Multiple Deliverable Revenue Arrangements. This standard provides application guidance on whether multiple deliverables exist, how the deliverables should be separated and how the consideration should be allocated to one or more units of accounting. This update establishes a selling price hierarchy for determining the selling price of a deliverable. The selling price used for each deliverable will be based on vendor-specific objective evidence, if available, third-party evidence if vendor-specific objective evidence is not available, or estimated selling price if neither vendor-specific or third-party evidence is available. This guidance is effective for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. The Company adopted this guidance effective August 1, 2010 which did not have an effect on its consolidated results of operations and financial condition.

Note 2 – Short-term Investments

At January 31, 2011 and July 31, 2010, the Company’s short-term investments, whose fair value approximates cost, are in U.S. Treasury bills, which are purchased at discounts with remaining maturities of under ninety days.

The authoritative guidance for fair value measurements establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under the guidance are described below:


	Level 1:	Valuations based on quoted market prices in active markets for identical assets or liabilities.

	Level 2:	Valuations based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.

	Level 3:	Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

At January 31, 2011 and July 31, 2010 the Company’s short-term investments are classified as Level 1 assets.

Note 3 – Net 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 the three and six months ended January 31, 2011 and 2010 do not include the potential common shares from stock options and unvested restricted stock because to do so would have been antidilutive. Accordingly, basic and diluted net loss per share is the same during these periods.

The following table summarizes the potential number of shares issued from exercise of “in the money” stock options, net of shares repurchased with the option exercise proceeds and potential shares from restricted stock awards, which are excluded from the computation of diluted net loss per share.

A summary of the activity relating to the Company’s stock option plans for the six month period ended January 31, 2011 is as follows:


	Options			Weighted Average Exercise Price		Aggregate Intrinsic Value

Outstanding at August 1, 2010		1,132,450		$	14.30	$	—

Exercised		—			—
Cancelled		(57,077	)	$	15.35

Outstanding and exercisable at end of period		1,075,373		$	14.25	$	—

As of January 31, 2011, there was no unrecognized compensation cost related to unvested stock option-based compensation.

Restricted Stock Awards

A summary of the activity pursuant to the Company’s restricted stock awards for the six months ended January 31, 2011 is as follows:


	Awards			Weighted Average Award Price

Unvested at August 1, 2010		417,578		$	5.50
Awarded		3,000		$	3.96
Vested		(102,323	)	$	5.14
Forfeited		(5,450	)	$	7.55

Unvested at end of period		312,805		$	5.57

The fair value of a restricted stock award is determined based on the closing stock price on the award date. As of January 31, 2011, there was approximately $0.9 million of unrecognized compensation cost related to unvested restricted stock-based compensation to be recognized over a weighted average remaining period of one year.

On January 14, 2011, the Company’s stockholders approved the adoption of the 2011 Incentive Plan (the “2011 Plan”) which provides for the issuance of equity awards, including among others, options, restricted stock and restricted stock units for up to 3,000,000 Common Shares. No additional awards may be granted under the 1999 or 2005 Plans. The exercise price of options granted under the 2011 Plan, and consistent with other Plans, is equal to or greater than fair market value of the Common Stock on the date of grant. Unless terminated earlier by the Board of Directors the 2011 Plan will terminate at the earliest of; (a) such time as no shares of Common Stock remain available for issuance under the 2011 Plan or (b) tenth anniversary of the effective date of the 2011 Plan. Awards outstanding upon expiration of the 2011 Plan shall remain in effect until they have been exercised, terminated, or have expired.

The total number of shares available for grant as equity awards is 3,000,000 as of January 31, 2011.

Note 10 - Income taxes

At the end of each interim reporting period, the Company estimates its effective income tax rate expected to be applicable for the full year. This estimate is used to determine the income tax provision or benefit on a year-to-date basis and may change in subsequent interim periods.

The Company’s effective tax rate for the three months ended January 31, 2011 was 2.6% compared to 1.2% during the three months ended January 31, 2010. The tax provision for the periods were based on state and local taxes, domestic and foreign tax for tax deductible goodwill and indefinite lived intangibles, and book to tax differences for inventory. The Company’s effective tax rate for the six months ended January 31, 2011 was 3.2% compared to 0.3% during the six months ended January 31, 2010. The tax provision for the periods were based on state and local taxes, domestic and foreign tax for tax deductible goodwill and indefinite lived intangibles, and book to tax differences for inventory.

The Company’s effective tax rate for both periods differed from the expected net operating loss carryforward benefit at the U.S. federal statutory rate of 34% primarily due to the inability to recognize such benefit. The carryforward benefit cannot be recognized 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 federal carryforward benefit.

The Company files a consolidated Federal income tax return. The Company files combined returns with California and New York State and City for certain subsidiaries. Other subsidiaries file separate state and foreign tax returns. With few exceptions, the periods that remain subject to examination are fiscal years ended July 31, 2007 through fiscal 2009.

The Company’s policy is to recognize interest and penalties accrued on any uncertain tax positions as a component of income tax expense. As of January 31, 2011, there is no liability related to unrecognized tax benefits.

Note 11 – Royalty and licensing income

The Company has a license agreement with QIAGEN Gaithersburg Inc. (“Qiagen”) that began in 2005, whereby the Company earns quarterly running royalties on the net sales of Qiagen products subject to the license until the expiration of the patent on April 24, 2018. During the three months ended January 31, 2011 and 2010, the Company recorded royalty income under the Agreement of approximately $1.2 million and $1.1 million, respectively. During each of the six months ended January 31, 2011 and 2010, the Company recorded royalty income under the Agreement of approximately $3.7 million.

In April 2007 Enzo Life Sciences, Inc. (“Life Sciences”) and Abbott Molecular Inc. (“Abbott”) entered into an agreement, which is still in effect, covering the supply of certain of Enzo Life Sciences products to Abbott for use in their product line. The parties also entered into a limited non-exclusive royalty bearing cross-licensing agreement (“Licensing Agreement”) for various patents. The Licensing Agreement requires each party to pay royalties, as defined through the lives of related non-expired patents. In connection with a component of the Licensing Agreement, Abbott paid a one-time fee of $1.5 million relating to a fully paid-up license and sublicense, as defined. The one-time fee was recognized as revenue through August 31, 2010 representing the longest expected patent life of the related patents. Abbott has notified Enzo that they have made a final royalty payment because they are unaware of any non-expired patents. Enzo is presently reviewing its patent portfolio and Abbott’s position. The Licensing Agreement between the parties remains in full force and effect and Enzo continues its commercialization efforts under the contract terms.

During the three months ended January 31, 2011, the Company recorded no royalties or license fees under the Licensing Agreement. During the three months ended January 31, 2010, the Company recorded approximately $0.7 million in royalties and license fee income under the Licensing Agreement. During the six months ended January 31, 2011 and 2010, the Company recorded $0.5 and $1.4 million, respectively in royalties and license fees from the Licensing Agreement. Royalty and licensing income is included in the Life Sciences segment.

Note 12 – Segment reporting

During the three months ended January 31, 2011, the Company recorded a $0.7 million out of period adjustment to increase cost of product revenues to correct for immaterial errors in the computation of the intercompany inventory profit elimination related to the three months ended October 31, 2010. The adjustment increased the three months ended January 31, 2011 net loss and net loss per share by $0.7 million and $0.02 per share, respectively. As a result of recording this adjustment during the three months ended January 31, 2011, the financial statements as of and for the six months ended January 31, 2011 are correctly stated.

The Company has three reportable segments: Life Sciences, Clinical Labs and Therapeutics. The Company’s Life Sciences segment develops, manufactures, and markets products to research and pharmaceutical customers. The Clinical Labs segment provides diagnostic services to the health care community. The Company’s Therapeutic segment conducts research and development activities for therapeutic drug candidates. The Company evaluates segment performance based on segment income (loss) before taxes. Costs excluded from segment income (loss) before taxes and reported as “Other”, consist of corporate general and administrative costs which are not allocable to the three reportable segments.

Management of the Company assesses assets on a consolidated basis only and, therefore, assets by reportable segment have not been included in the reportable segments below. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies.

The following financial information represents the operating results of the reportable segments of the Company:

Note 13 - Contingencies

On or about September 22, 2010, Mayflower Partners, L.P. f/k/a Biomol International, L.P. (“Mayflower”) filed an action against Enzo Biochem, Inc. and Enzo Life Sciences, Inc. (together “Enzo”) in the United States District Court for the Southern District of New York, alleging breach of the stock and asset purchase agreement dated as of May 8, 2008 between Enzo and Mayflower (the “Agreement”). Pursuant to the Agreement, the Company acquired the assets of Mayflower, and agreed, among other things, to make certain contingent earn-out payments to Mayflower, accounted for as additional purchase price consideration, if certain performance thresholds were met for each of the two annual periods following the closing. Mayflower alleges that Enzo breached the Agreement by allegedly failing to operate the acquired business in good faith during the second earn-out period and engaging in conduct the primary purpose of which was to avoid making a second earn-out period payment under the Agreement. In addition, Mayflower claims that Enzo breached the Agreement by allegedly failing to provide the documentation appropriate to support the calculation of defined financial criteria for the second earn-out period as required under the Agreement. As part of the litigation, Mayflower moved by Order to Show cause to enjoin the accounting procedure specified under the Agreement. Mayflower’s motion was heard by a U.S. District Court Judge on September 27, 2010, who directed that the parties first go forward with the accounting procedure, as provided under the Agreement, before moving further with the litigation. The parties were unable to resolve the dispute through the accounting procedure. On January 27, 2011, Mayflower filed an amended complaint. On February 25, 2011, Enzo filed an answer to the amended complaint and on March 4, 2011 filed an amended counterclaim seeking fees and expense of the suit as provided under the Agreement. As provided under the Agreement, Mayflower’s maximum recovery in the event that it is successful on either the accounting or in litigation is settlement of the $2.5 million contingent earn-out in either Enzo common stock or cash, as set forth in the Agreement, plus attorney’s fees. Enzo denies that it is in breach of the Agreement and will vigorously defend the suit.

Lawrence F. Glaser and Maureen Glaser, individually and on behalf of Kimberly, Erin, Hannah, and Benjamin Glaser v. Hyman Gross, Barry Weiner, Enzo Biochemical Inc., Elazar Rabbani, Shahram Rabbani, John Delucca, Dean Engelhardt, Richard Keating, Doug Yates, and Does 1-50, Case No. CA-02-1242-A, U.S. District Court for the Eastern District of Virginia. This action was commenced on or about March 6, 2002 by an investor in the Company who had filed for bankruptcy protection and for his family. The complaint alleged securities and common law fraud and breach of fiduciary duty and sought in excess of $150 million in damages. On August 22, 2002, the complaint was voluntarily dismissed; however a new substantially similar complaint was filed at the same time. On October 21, 2002, the Company and the other defendants filed a motion to dismiss the complaint, and the plaintiffs responded by amending the complaint and dropping their claims against defendants Keating and Yates. On November 18, 2002, the Company and the other defendants again moved to dismiss the Amended Complaint. On July 16, 2003, the Court issued a Memorandum Opinion dismissing the Amended Complaint in its entirety with prejudice. Plaintiffs thereafter moved for reconsideration but the Court denied the motion on September 8, 2003. Plaintiffs thereafter appealed the decision to the United States Court of Appeals for the Fourth Circuit. On March 21, 2005, the Fourth Circuit affirmed the lower Court’s prior dismissal of all claims asserted in the action with the sole exception of a portion of the claim for common law fraud and remanded that remaining portion of the action to the U.S. District Court for the Eastern District of Virginia. On May 20, 2005, defendants again moved the District Court to dismiss the sole remaining claim before it. On July 14, 2005, the District Court granted defendants’ renewed motion to dismiss. On July 29, 2005, Plaintiffs moved to amend their Complaint and for reconsideration. On August 19, 2005, the Court denied Plaintiffs’ motion to amend and entered final judgment dismissing the Complaint. Plaintiffs then appealed the order and judgment to the Fourth Circuit. On September 21, 2006, the United States Court of Appeals for the Fourth Circuit affirmed the dismissal of the Complaint. Thereafter, in March 2007, the United States Supreme Court denied the Glazers’ Petition for Certiorari. Nevertheless, on January 14, 2011, many years after it was finally dismissed, Glaser filed a motion for reconsideration of the dismissal of his case with the United States District Court for the Eastern District of Virginia, along with a motion for sanctions, claiming in pertinent part that the Court was defrauded. The Company has filed papers in opposition to the motion which is currently pending before the Court. The Company believes that the Glazers’ latest filing is frivolous and that it will be rejected by the Court, and intends in all events to defend vigorously any effort to re-open this long ago dismissed action.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes and other information included elsewhere in this Quarterly Report on Form 10-Q.

In particular, these include statements relating to future actions, prospective products or product approvals, future performance or results of current and anticipated products, sales efforts, expenses, interest rates, foreign exchange rates, intellectual property matters, the outcome of contingencies, such as legal proceedings, and financial results.

We cannot guarantee that any forward-looking statement will be realized, although we believe we have been prudent in our plans and assumptions. Achievement of future results is subject to risks, uncertainties and inaccurate assumptions. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could vary materially from past results and those anticipated, estimated or projected. As a result, investors are cautioned not to place undue reliance on any of our forward-looking statements. Investors should bear this in mind as they consider forward-looking statements.

We do not assume any obligation to update or revise any forward-looking statement that we make, even if new information becomes available or other events occur in the future. We are also affected by other factors that may be identified from time to time in our filings with the Securities and Exchange Commission, some of which are set forth in Item 1A - Risk Factors in our Form 10-K filing for the 2010 fiscal year. You are advised to consult any further disclosures we make on related subjects in our Forms 10-Q, 8-K and 10-K reports to the Securities and Exchange Commission. Although we have attempted to provide a list of important factors which may affect our business, investors are cautioned that other factors may prove to be important in the future and could affect our operating results. You should understand that it is not possible to predict or identify all such factors or to assess the impact of each factor or combination of factors on our business.

Consolidated Results:

The “2011 period” and the “2010 period” refer to the three months ended January 31, 2011 and 2010, respectively.

Product revenues during the 2011 period was $10.2 million as compared to $10.7 million in the 2010 period, a decrease of $0.5 million or 5%, primarily due to the termination of certain supply agreements by the suppliers. The Company continuously analyzes the market to identify and enter into agreements with new suppliers.

Royalty and license fee income during the 2011 period was $1.2 million compared to $1.8 million in the 2010 period, a decrease of $0.6 million or 34%. The 2011 period royalties were earned from the reported net sales of Qiagen products subject to a license agreement and represent an increase of $0.1 million as compared to Qiagen royalties of $1.1 million in the 2010 period. During the 2011 period, the Company recognized no royalties or license fees from the Abbott licensing agreement. Abbott has notified Enzo that they have made a final royalty payment because they are unaware of any non-expired patents. Enzo is presently reviewing its patent portfolio and Abbott’s position. The licensing agreement between the parties remains in full force and effect and Enzo continues its commercialization efforts under the contract terms. In the 2010 period, royalties and license fees from the Abbott licensing agreement were $0.7 million. There are no direct expenses relating to royalty and license fee income.

Clinical laboratory revenues during the 2011 period were $12.3 million compared to $10.6 million in the 2010 period, an increase of $1.7 million or 16%. During the 2011 period, revenue increased due to net organic growth of 10% and an incremental increase of 6% in revenue related to a new payer contract with Empire Blue Cross of New York, effective August 1, 2010.

The cost of product revenues during the 2011 period was $5.9 million compared to $5.3 million in the 2010 period, an increase of $0.6 million or 11%. During the 2011 period, the Company recorded a $0.7 million out of period adjustment to increase cost of product revenues to correct for immaterial errors in the computation of the intercompany inventory profit elimination related to the three months ended October 31, 2010. The adjustment increased the three months ended January 31, 2011 net loss and net loss per share by $0.7 million and $0.02 per share, respectively. As a result of recording this adjustment during the three months ended January 31, 2011, the financial statements as of and for the six months ended January 31, 2011 are correctly stated. The 2011 period was also negatively impacted by higher salaries and other costs of production and the effect of volume and mix. The above increases were offset by lower costs attributed to the decline in product revenues.

The cost of clinical laboratory services during the 2011 period was $7.5 million as compared to $7.0 million in the 2010 period, an increase of $0.5 million or 7%. The Company incurred increased costs due to higher reagent costs and supplies of $0.5 million attributed to increased service volume, and higher personnel related costs of $0.2 million offset by a decrease in outside reference lab costs of $0.2 million. Reagent costs increased due to higher service volume and for certain tests that were previously sent to outside reference labs.

Research and development expenses were approximately $2.0 million during the 2011 period, compared to $2.3 million in the 2010 period, a decrease of $0.3 million or 14%. The decrease was attributed to lower costs of $0.2 million at Enzo Life Sciences primarily due to the realignment of the research and development workforce that occurred in July 2010 and a $0.1 million decline in clinical trial and related activities at the Therapeutics segment.

Selling, general and administrative expenses were approximately $11.5 million during the 2011 period as compared to $13.5 million in the 2010 period, a decrease of $2.0 million or 15%. The Enzo Life Sciences segment experienced a decrease of $0.7 million in the 2011 period primarily attributed to a decline of $0.2 million of marketing costs due to refocused spending, a $0.2 million decline in payroll related costs, $0.1 million decline related to changes in expense allocation, and the balance due to general decreases. At the Clinical Labs segment selling, general and administrative expenses decreased by $0.5 million primarily due to a decline in payroll of $0.1 million, a decrease in group medical benefit costs of $0.3 million, and a $0.2 million decrease in the 401(k) employer match which has been accrued quarterly as compared to the annual discretionary employer match in the 2010 period offset by a $0.1 million increase in sales commissions directly attributed to the increase in service revenues.. The Other segment’s general and administrative expenses decreased by $0.8 million during the 2011 period primarily due to decreases in outside consulting costs of $0.3 million, professional fees of $0.2 million and payroll and payroll related costs of $0.3 million due to quarterly bonus accruals in the 2011 period, as compared to annual discretionary bonus in the 2010 period.

The provision for uncollectible accounts receivable, primarily relating to the Clinical Labs segment was $0.9 million for the 2011 period as compared to $0.5 million in the 2010 period, an increase of $0.4 million or 88%. As a percentage of Clinical Labs revenues the provision for uncollectible accounts increased to 7.8% in the 2011 period as compared to 4.8% in the 2010 period. The increase is attributed to the additional provision required due to increased service volume and changes in payer mix.

Legal expense was $1.4 million during the 2011 period compared to $0.8 million in the 2010 period, an increase of $0.6 million or 67% due to overall increases in legal services in the 2011 period relating to general legal and proxy matters.

During the 2010 period, in connection with the litigation settlement with Mr. Shahram K. Rabbani to settle all of his claims against the Company and certain of its executive officers, the Company agreed to pay a lump sum payment of $2.7 million. The Company recorded a settlement expense of approximately $3.7 million, consisting of the lump sum payment of $2.7 million and approximately $1.0 million of legal expenses incurred in connection with the claims.

Segment Results

The Life Sciences segment’s loss before taxes was $0.4 million for the 2011 period as compared to income before taxes of $0.4 million for the 2010 period. Product revenues decreased by $0.5 million in the 2011 period primarily due to termination of certain supply agreements by the suppliers. The Company continuously analyzes the market to identify and enter into agreements with new suppliers. Royalty and license fee income decreased by $0.6 million in the 2011 period due to the decrease in royalties from the Abbott license agreement. The segment’s 2011 period gross profit of $5.5 million was negatively impacted by the previously discussed changes in revenues and cost of product revenues. The segment’s other operating expenses, including selling, general and administrative, legal and research and development, decreased by approximately $0.8 million during the 2011 period due to the lower marketing and selling expenses attributed to refocused and lower planned spending, lower payroll related costs, reduced research and development expenses principally due to the realignment of research and development workforce that occurred in July 2010, and the balance attributed to a decline in other general costs also part of the effort to reduce and refocus spending.

The Clinical Labs segment’s loss before taxes was $0.8 million for the 2011 period as compared to a loss of $2.0 million in the 2010 period. The revenue from laboratory services increased in the 2011 period by $1.7 million or 16% due to increased service volume due to net organic growth and the increased revenue due to the new payer contract with Empire Blue Cross of New York, effective August 2010. The 2011 period gross profit of $4.8 million increased due to the previously discussed changes in revenues and cost of clinical laboratory services volume. In the 2011 period, selling, general and administrative expense decreased by approximately $0.5 million primarily due to decreases in payroll, group medical benefit related costs, and 401(k) employer match costs, partially offset by increases in sales commissions. As a percentage of revenues, selling, general and administrative decreased to 37% from 48%. The provision for uncollectible accounts receivables increased by $0.4 million as compared to the 2010 period due the increased revenues and changes in payer mix.

The Therapeutics segment’s loss before income taxes was approximately $0.5 million for the 2011 period as compared to $0.6 million for the 2010 period. The decrease of $0.1 million in the 2011 period was primarily due to decreases in clinical trial activities due to the timing of such expenses being incurred and decreases in payroll related expenses.

The Other segment’s loss before taxes for the 2011 period was approximately $3.8 million as compared to $7.9 million in the 2010 period, a decrease of $4.1 million. For the 2011 period overall general and administrative expenses decreased by $0.8 million, including professional fees and payroll and benefit costs, partially attributed to the quarterly recording of bonuses as compared to the annual recording of discretionary bonuses in the 2010 period. Legal costs increased by $0.4 million over the 2010 period due increased general legal matters and proxy related costs. The 2010 period loss includes the litigation settlement and related legal costs of $3.7 million.

Consolidated Results:

The “2011 period” and the “2010 period” refer to the six months ended January 31, 2011 and 2010, respectively.

Product revenues in the 2011 period was $20.4 million as compared to $21.5 million in the 2010 period, a decrease of $1.1 million or 5% primarily due to the termination of certain supply agreements by the suppliers. The Company continuously analyzes the market to identify and enter into agreements with new suppliers. The negative impact of foreign exchange was $0.1 million.

Royalty and license fee income during the 2011 period was $4.3 million compared to $5.1 million in the 2010 period, a decrease of $0.8 million or 17%. Royalties are primarily earned from the reported net sales of Qiagen products subject to a license agreement. During both the 2011 and 2010 periods, the Company recognized royalties of approximately $3.7 million from Qiagen. During the 2011 period, the Company recognized royalties and license fees from the Abbott license agreement of $0.5 million, a decrease of $0.9 million compared to the 2010 period. Abbott has notified Enzo that they have made a final royalty payment because they are unaware of any non-expired patents. Enzo is presently reviewing its patent portfolio and Abbott’s position. The Licensing Agreement between the parties remains in full force and effect and Enzo continues its commercialization efforts under the contract terms. The Company earned other royalties of $0.1 million during the 2011 period. There are no direct expenses relating to royalty and license fee income.

Clinical laboratory revenues during the 2011 period were $24.7 million compared to $21.7 million in the 2010 period, an increase of $3.0 million or 14%. During the 2011 period, revenue increased due to increased service volume from net organic growth of 9% and an incremental increase of 5% in revenue related to a new payer contract with Empire Blue Cross of New York, effective August 1, 2010.

The cost of product revenues during the 2011 period was $10.5 million compared to $10.4 million in the 2010 period, an increase of $0.1 million or 1%. Although product sales declined during the 2011 period, cost of product revenues was negatively impacted by higher salaries, other costs of production and product mix aggregating $0.6 million.

The cost of clinical laboratory services during the 2011 period was $15.1 million as compared to $13.8 million in the 2010 period, an increase of $1.3 million or 9%. The Company incurred increased costs attributed to increased service volume such as higher reagent costs and supplies of $1.0 million, and higher laboratory personnel and related costs of $0.5 million offset by a decrease in outside reference lab costs of $0.2 million. Reagent costs increased due to higher service volume and for certain tests that were previously sent to outside reference labs. Laboratory personnel and related costs increased primarily from the expansion of the patient service centers and incremental costs for a senior management individual hired during the second half of fiscal year 2010 offset by the realignment of personnel in July 2010 and other personnel related costs.

Research and development expenses were approximately $3.8 million during the 2011 period, compared to $4.8 million in the 2010 period, a decrease of $1.0 million or 21%. The decrease was attributed to lower costs of $0.7 million at Enzo Life Sciences primarily due to the realignment of the research and development workforce that occurred in July 2010 and a $0.3 million decline in clinical trial and related activities and payroll costs at the Therapeutics segment.

Selling, general and administrative expenses were approximately $22.6 million during the 2011 period as compared to $25.1 million in the 2010 period, a decrease of $2.5 million or 10%. The Enzo Life Sciences segment’s selling, general and administrative expenses declined by $1.6 million in the 2011 period, comprised of a decline of $0.8 million of marketing costs due to refocused and lower planned spending, a $0.5 million decline in payroll related costs, a $0.1 million decline related to changes in expense allocation, and the balance to a decline in other general costs. The Clinical Labs segment’s selling, general and administrative costs decreased by $0.1 million due to decreased group medical benefit costs of $0.3 million and $0.1 million in 401(k) employer match as compared to the annual discretionary match in the 2010 period, offset by increases in payroll costs of $0.1 million due to quarterly bonus accruals in the 2011 period as compared to the annual discretionary bonus in the 2010 period, and an increase of $0.2 million in sales commissions attributed to the increase in service volume. The Other segment’s general and administrative expenses decreased by $0.8 million primarily due to the decreases in outside consulting costs of $0.5 million and professional fees of $0.3 million.

The provision for uncollectible accounts receivable, primarily relating to the Clinical Labs segment was $2.0 million for the 2011 period as compared to $1.4 million in the 2010 period, an increase of $0.6 million. As a percentage of revenues the provision for uncollectible accounts increased to 8.2% in the 2011 period as compared to 6.6% in the 2010 period. The increase is attributed the additional provision required due to increased service volume and changes in payer mix.

Legal expense was $2.1 million during the 2011 period compared to $1.1 million in the 2010 period. After giving effect to the non-recurring reimbursement in the 2010 period of $0.5 million in legal costs under our insurance policy, the overall increase in legal services in the 2011 period relates to general legal and proxy related matters.

During the 2010 period, in connection with the litigation settlement with Mr. Shahram K. Rabbani to settle all of his claims against the Company, and certain of its executive officers, the Company agreed to pay a lump sum payment of $2.7 million. The Company recorded a settlement expense of approximately $3.7 million, consisting of the lump sum payment of $2.7 million and approximately $1.0 million of legal expenses incurred in connection with the claims.

During the 2011 and 2010 periods, the loss on foreign currency transactions was $0.1 million and $0.2 million respectively. The 2011 period loss was due to the impact European currency fluctuations had on settled transactions. The 2010 period loss was primarily due to a non-cash loss on an intercompany term loan denominated in British pounds sterling.

Segment Results

The Life Sciences segment’s income before taxes was $2.6 million for the 2011 period as compared to $2.3 million for the 2010 period. Product revenues decreased by $1.1 million in the 2011 period primarily due to termination of certain supply agreements by the suppliers. The Company continuously analyzes the market to identify and enter into agreements with new suppliers. The decrease in royalty and license fee income of $0.8 million in the 2011 period was attributed to decreases in royalty and fee income from the Abbott license agreement after the first quarter of the 2011 period. The segment’s gross profit of $14.2 million in the 2011 period was negatively impacted by the previously discussed changes in revenues and cost of product revenues. The segment’s other operating expenses, including selling, general and administrative, legal and research and development, decreased by approximately $2.2 million during the 2011 period primarily due to the lower marketing and selling expenses attributed to refocused and lower planned spending, a decline in payroll related costs, reduced research and development expenses principally due to the realignment of research and development workforce that occurred in July 2010, and the balance to a decline in other general costs, also part of the effort to reduce and refocus spending.

The Clinical Labs segment’s loss before taxes was $1.7 million for the 2011 period as compared to a loss of $2.8 million in the 2010 period. The revenue from laboratory services increased in the 2011 period by $3.0 million due to increased service volume from net organic growth of 9% and the 5% increase in revenue due to the new payer contract with Empire Blue Cross of New York effective August 2010. The 2011 period gross profit of $9.6 million improved over the 2010 period due to the previously discussed changes in service revenues and cost of laboratory services. Selling, general and administrative expense decreased by approximately $0.1 million primarily due to decreases in group medical benefit costs and 401(k) employer match, partially offset by increases in payroll and sales commissions costs. The provision for uncollectible accounts receivables increased by $0.6 million as compared to the 2010 period due to the increase in service volume and changes in payer mix.

The Therapeutics segment’s loss before income taxes was approximately $1.0 million for the 2011 period as compared to a loss of $1.3 million for the 2010 period. The decrease in the segment loss of $0.3 million was primarily due to decreases in clinical trial activities due to timing of such expenses being incurred and a decrease in payroll related expenses.

The Other segment’s loss before taxes for the 2011 period was approximately $6.6 million as compared to $10.4 million in the 2010 period, a decrease of $3.8 million. During the 2011 period, there was an increase in other income of $0.1 million and a decrease of $0.8 million in selling, general and administrative due to lower consulting costs and professional fees, partially attributed to the July 2010 planned cost reductions offset by an increase of $0.8 million in legal fees for general legal and proxy related costs. Further, the 2010 period loss included a litigation settlement and related legal costs of $3.7 million.

Liquidity and Capital Resources

At January 31, 2011, the Company had cash and cash equivalents of $9.0 million and short-term investments of $21.8 million, or $30.8 million in aggregate as compared to $33.6 million at July 31, 2010. Short term investments are in U.S. Government Treasury bills. The Company had working capital of $37.5 million at January 31, 2011 compared to $42.2 million at July 31, 2010. The decrease in working capital of $4.7 million was primarily the result of the net loss and funding capital expenditures during the 2011 period.

Net cash used in operating activities for the six months ended January 31, 2011 was approximately $2.2 million as compared to $3.7 million for the six months ended January 31, 2010. The decrease in net cash used in operating activities in the 2011 period over the 2010 period of approximately $1.6 million was primarily attributed to the decrease in the net loss of $5.3 million, and an increase in non-cash adjustments in the 2011 period over the 2010 period of $0.6 million offset by a net decrease in the changes in operating assets and liabilities of $4.3 million from the 2010 to 2011 period, primarily relating to accounts receivable, inventories and accrued liabilities.

Net cash provided by investing activities was approximately $2.3 million compared to $4.9 million in the year ago period, a decrease of $2.7 million. The decrease is primarily due to the net maturities of short term investments in US Government instruments of $3.0 million in the 2011 period as compared to $7.0 million in the 2010 period offset by capital expenditures of $0.6 million in 2011 period as compared to $2.0 million in the 2010 period.

Biomol International L.P.

The Company believes that its current cash position is sufficient for its foreseeable liquidity and capital resource needs over the next 12 months, although there can be no assurance that future events will not alter such view.

Contractual Obligations

There have been no material changes to our Contractual Obligations as reported in our Form 10-K for the fiscal year ended July 31, 2010.

Management is not aware of any material claims, disputes or settled matters concerning third party reimbursement that would have a material effect on our financial statements.

Off Balance Sheet Arrangements

The Company does not have any “off balance sheet arrangements” as such term is defined in Item 303(a)(4) of Regulation S-K.

Critical Accounting Policies

The Company’s discussion and analysis of its financial condition and results of operations are based upon Enzo Biochem, Inc.’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses; these estimates and judgments also affect related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to contractual adjustments, allowance for uncollectible accounts, inventory, intangible assets and income taxes. The Company bases its estimates on experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Product revenues

Revenues from product sales are recognized when the products are shipped and title transfers, the sales price is fixed or determinable and collectibility is reasonably assured.

Royalties

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

License fees and multiple element arrangements

When evaluating multiple element arrangements, the Company considers whether the components of the arrangement represent separate units of accounting, which requires subjective determinations and requires management to make judgments about the fair value of the individual elements and whether such elements are separable from the other aspects of the contractual relationship.

Revenues – Clinical laboratory services

Revenues from Clinical Labs 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 approved reimbursable settlements from such payers.

The following are tables of the Clinical Labs segment’s net revenues and percentages by revenue category for the three and six months ended January 31, 2011 and 2010:

Net revenues


	Three months ended January 31, 2011				Three months ended January 31, 2010

Revenue category
Medicare	$	2,845	23	%	$	2,716	26	%
Third-party payer		5,703	46			4,681	44
Patient self-pay		2,512	21			2,020	19
HMO’s		1,218	10			1,163	11

Total	$	12,278	100	%	$	10,580	100	%

Net revenues


	Six months ended January 31, 2011				Six months ended January 31, 2010

Revenue category
Medicare	$	5,624	23	%	$	5,570	26	%
Third-party payer		11,327	46			9,551	44
Patient self-pay		5,201	21			4,157	19
HMO’s		2,516	10			2,412	11

Total	$	24,668	100	%	$	21,690	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. The Company believes that it is in compliance with all applicable laws and regulations and is not aware of any pending or threatened investigations involving allegations of potential wrongdoing.

Other than the Medicare program, one provider whose programs are included in the Third-party payer and Health Maintenance Organizations (“HMO’s”) categories represented 22% and 25% of the Clinical Labs net revenues for the three months ended January 31, 2011 and 2010, respectively, and 22% and 26% for the six months ended January 31, 2011 and 2010, 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 we set for all third party payers, including Medicare, HMO’s and managed care. 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.

The other relevant factors that affect our contractual adjustment include the monthly and quarterly review of: 1) current gross billings and receivables and reimbursement by payer, 2) current changes in third party arrangements, 3) the growth of in-network provider arrangements and managed care plans specific to our Company.

Our clinical laboratory business is primarily dependent upon reimbursement from third-party payers, such as Medicare (which principally serves patients 65 and older) and insurers. We are subject to variances in reimbursement rates among different third-party payers, as well as constant changes of reimbursement rates. Changes that decrease reimbursement rates or coverage would negatively impact our revenues. The number of individuals covered under managed care contracts or other similar arrangements has grown over the past several years and may continue to grow in the future. In addition, Medicare and other government healthcare programs continue to shift to managed care. These trends will continue to reduce our revenues.

During the three months ended January 31, 2011 and 2010, the contractual adjustment percentages, determined using current and historical reimbursement statistics, were 84.1% and 83.1, respectively, of gross billings. During the six months ended January 31, 2011 and 2010, the contractual adjustment percentages, determined using current and historical reimbursement statistics, were 83.9% and 82.8%, respectively, of gross billings. The Company believes the negative impact on revenues from the decline in reimbursement rates or the shift to managed care, other primary third party payers, or similar arrangements may be offset by the positive impact of the number of tests we perform. However, there can be no assurance that we can increase the number of tests we perform or that if we do increase the number of tests we perform, that we can maintain that higher number of tests performed, or that an increase in the number of tests we perform would result in increased revenue.

The Company estimates (by using a sensitivity analysis) that each 1% point change in the contractual adjustment percentage could result in a change in clinical laboratory services revenues of approximately $1,523,000 and $1,260,000 for the six months ended January 31, 2011 and 2010, respectively, and a change in the net accounts receivable of approximately $369,000 as of January 31, 2011.

Our clinical laboratory financial billing system records gross billings using a standard fee schedule for all payers and does not record contractual adjustment by payer at the time of billing. Adjustments to our standard fee schedule will impact the contractual adjustment recorded. Therefore, we are unable to quantify the effect of contractual adjustment recorded during the current period that relates to revenue recorded in a previous period. However, we can reasonably estimate our contractual adjustment to revenue on a timely basis based on our quarterly review process, which includes:


	•	an analysis of industry reimbursement trends;

	•	an evaluation of third-party reimbursement rates changes and changes in reimbursement arrangements with third-party payers;

	•	a variance reimbursement analysis of current and historical claim settlement and reimbursement experience with payers;

	•	an analysis of current gross billings, receivables, and collections by payer.

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.

The following is a table of the Company’s net accounts receivable by segment. The Clinical Labs segment’s net receivables are detailed by billing category and as a percent to its total net receivables. At January 31, 2011 and July 31, 2010, approximately 49% and 45%, 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, of which approximately $2.3 million or 36% and $2.0 million or 28% represents foreign receivables as of January 31, 2011 and July 31, 2010 respectively, includes royalty receivables of $1.2 million and $3.2 million, as of January 31, 2011 and July 31, 2010, respectively, of which approximately $1.2 million and $2.6 million, respectively is from Qiagen Corporation (Note 11).

Net accounts receivable


Billing category	As of January 31, 2011				As of July 31, 2010

Clinical Labs
Medicare	$	942	15	%	$	849	14	%
Third party payers		2,372	39			2,664	46
Patient self-pay		2,544	41			2,024	35
HMO’s		285	5			296	5

Total Clinical Labs		6,143	100	%		5,833	100	%

Total Life Sciences		6,410				7,173

Total accounts receivable	$	12,553			$	13,006

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


	Six months ended January 31, 2011			Twelve months ended July 31, 2010

Beginning balance	$	2,839		$	4,786
Provision for doubtful accounts		2,032			3,480
Write-offs, net		(1,504	)		(5,427	)

Ending balance	$	3,367		$	2,839

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, the historical doubtful account write-off percentages, payer mix, and other relevant factors.

The allowance for doubtful accounts includes the balances, after receipt of the approved settlements from third party payers for the insufficient diagnosis information received from the ordering physician, which result in denials of payment and the uncollectible portion of receivables from self payers, including deductibles and copayments, which are subject to credit risk and patients’ ability to pay. During the six months ended January 31, 2011 and 2010, the Company determined an allowance for doubtful accounts less than 210 days and wrote off 100% of accounts receivable over 210 days, as it assumed those accounts are 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’s collection experience on Medicare receivables beyond 210 days has been insignificant. 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 or reimbursement issues in order to assess the impact, if any, on the allowance estimates, which involves judgment.

The Company believes that the collectibility 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 following table indicates the Clinical Labs aged gross receivables by payer group which is prior to adjustment to gross receivables for: 1) contractual adjustment, 2) fully reserved balances not yet written off, and 3) other revenue adjustments.

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 where it is not more likely than not the benefits will be realized in the foreseeable future.

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. The Company adopted the accounting standard related to unrecognized tax benefits on August 1, 2007. The cumulative effect of adopting the standard did not have a material impact on the Company’s financial position or results of operations.

Inventory

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.

Goodwill and Indefinite-Lived Intangibles

Goodwill, representing the cost of acquired businesses in excess of the fair value of net assets acquired, and indefinite-lived intangibles are not amortized, but are evaluated annually for impairment. The Company performs its annual impairment test as of the first day of its fiscal fourth quarter or on an earlier date if indicators of potential impairment exist. Goodwill is considered impaired if the carrying amount of the reporting unit exceeds its estimated fair value. In assessing the recoverability of goodwill, the Company reviews both quantitative as well as qualitative factors to support its assumptions with regard to fair value. The fair value of a reporting unit, which is based on geographic region, is estimated using both a discounted cash flow model and weighted average multiple of revenues and earnings before interest, taxes, depreciation and amortization.

In determining fair value, the Company makes certain judgments, including the identification of reporting units and the selection of comparable companies. Trademarks are considered impaired if the carrying amount exceeds their estimated fair value. The fair value of the trademarks is estimated based on a discounted cash flow model. If these estimates or their related assumptions change in the future as a result of changes in strategy and/or market conditions, the Company may be required to record an impairment charge. To date, there has been no impairment charges recorded.

Intangible Assets

Intangible assets (exclusive of patents), arose primarily from acquisitions and primarily consist of customer relationships, trademarks, licenses, employment and non-compete agreements, 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 relating to that patent is immediately expensed.

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. As of January 31, 2011, the Company has established a reserve of $0.3 million, which is included in accrued liabilities, for claims that have been reported but not paid and for claims incurred but not reported.

Recent Accounting Pronouncements

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk from changes in foreign currency exchange rates and, to a much lesser extent, interest rates on investments in short-term instruments, which could impact our results of operations and financial position. We do not currently engage in any hedging or market risk management tools. There have been no material changes with respect to market risk previously disclosed in our Annual Report on Form 10-K for our 2010 fiscal year.

Foreign Currency Exchange Rate Risk

The financial reporting of our non-U.S. subsidiaries is denominated in currencies other than the U.S. dollar. Since the functional currency of our non-U.S. subsidiaries is the local currency, foreign currency translation adjustments are accumulated as a component of accumulated other comprehensive income in stockholders’ equity. Assuming a hypothetical aggregate change of 10% in the exchange rates of foreign currencies against the U.S. dollar at January 31, 2011, our assets and liabilities would increase or decrease by $2.0 million and $0.9 million, respectively, and our net sales and net (loss) or earnings would increase or decrease by $1.5 million and $0.1 million, respectively, on an annual basis.

We also maintain intercompany balances and loans receivable with subsidiaries with different local currencies. These amounts are at risk of foreign exchange losses if exchange rates fluctuate. Assuming a hypothetical aggregate change of 10% in the exchange rates of foreign currencies against the U.S. dollar at January 31, 2011, our pre-tax earnings would be favorably or unfavorably impacted by approximately $0.3 million, on an annual basis.

Interest Rate Risk

Our excess cash is invested in highly liquid short term money market funds and short term investments in U.S. Treasury bills. Changes in interest rates may affect the investment income we earn on money market funds and short term investments and therefore affect our cash flows and results of operations. As of January 31, 2011, we were exposed to interest rate change market risk with respect to our money market accounts and short term investments totaling $23.8 million. The money market accounts and short-term investments yield or bear interest rates ranging from 0% to 0.4%. As of January 31, 2011, based on the investments held, it is determined that we have no material interest rate risk.

As of January 31, 2011, we did not maintain any fixed or variable interest rate financing.

Item 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, the Company’s management conducted an evaluation (as required under Rules 13a-15(b) and 15d-15(b) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of the Company’s “disclosure controls and procedures” (as such term is defined under the Exchange Act), under the supervision and with the participation of the principal executive officer and the principal financial officer. Based on this evaluation, the principal executive officer and the principal financial officer concluded that the Company’s disclosure controls and procedures are effective as of the end of the period covered by this report. Notwithstanding the foregoing, a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that it will detect or uncover failures within the Company to disclose material information otherwise required to be set forth in the Company’s periodic reports.

(b) Changes in Internal Controls over Financial Reporting

There was no change in the Company’s internal controls over financial reporting during the fiscal quarter covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
