Explanatory Note

In this Quarterly Report on Form 10-Q (“Form 10-Q”), we are restating our condensed consolidated statement of operations for the three and six months ended June 30, 2006 and our condensed consolidated statement of cash flows for the six months ended June 30, 2006.   In our Annual Report on Form 10-K for the year ended December 31, 2006, we restated our consolidated financial statements as of December 31, 2005 and for each of the years ended December 31, 2005 and 2004, and quarterly data for 2005 and the first two quarters of 2006.  Our previously filed Quarterly Report on Form 10-Q for the quarter ended June 30, 2006 affected by the restatement disclosed herein has not been amended and no reliance should be placed upon it.

The restatement of our consolidated financial statements reflects:

i)stock-based compensation expense not previously recorded for certain stock option grants for which we used an incorrect measurement date for accounting purposes;

ii)tax-related adjustments resulting from the above errors in stock option accounting; and

iii)the recording of previously unrecorded adjustments not related to accounting for stock options that were previously deemed to be immaterial to our historical consolidated financial statements.

During the quarter ended September 30, 2006 our Board of Directors formed a Special Committee of independent directors to commence a voluntary investigation of our historical stock option grants and practices. The Special Committee concluded that the appropriate measurement dates for determining the accounting treatment of certain historical stock option grants differed from the measurement dates we used in preparing our consolidated financial statements. Because the exercise prices at the originally stated grant dates, in certain cases, were lower than the prices on the revised measurement dates, we determined we should have recognized material amounts of stock-based compensation expense which were not accounted for in our previously issued consolidated financial statements. The Special Committee also found that in a number of instances the date and exercise price of option grants had been determined with hindsight to provide a more favorable price for such grants.

As a result, we have determined revised measurement dates for certain stock option grants and have recorded total additional stock-based compensation expense of $10.0 million for the years ended December 31, 2000 through 2005, and $0.1 million for the first two quarters of 2006.  A summary of additional stock-based compensation expense, by period, with the most significant stock option grants shown separately, is as follows:            

(000’s)	Year Ended December 31,														Three Months Ended June 30,		Six Months Ended June 30,
Grant Date	2000		2001		2002		2003		2004		2005		Total		2006		2006
May 25, 2000	$	1,540	$	2,699	$	3,028	$	281	$	135	$	—	$	7,683	$	—	$	—
Nov. 15, 2001					554		391		39		39		1,023
Aug. 11, 2003							47		185		162		394		20		40
All other grants	118		186		196		92		144		136		872		37		52
Total	$	1,658	$	2,885	$	3,778	$	811	$	503	$	337	$	9,972	$	57	$	92

As a result of determining revised measurement dates, we have also recorded payroll withholding tax related adjustments for certain options previously classified as Incentive Stock Option (“ISO”) grants under the Internal Revenue Service Code of 1986, as amended (“the Code”).  Such options were determined to have been granted with an exercise price below the fair market value of our common stock on the revised measurement date. As a result, such options do not qualify for ISO tax treatment. The disqualification of ISO classification and the resulting conversion to non-qualified stock option status results in additional withholding taxes on exercise of such options.  We have accordingly recorded a tax liability of $0.3 million and $0.5 million as of June 30, 2007 and December 31, 2006, respectively, in connection with the disqualification of such ISO tax treatment.

In addition, as a result of the change in the measurement dates of certain stock option grants, certain options vesting subsequent to December 2004 result in non-qualified deferred compensation for purposes of Section 409A of the Code, and holders are subject to an excise tax on the value of the options in the year in which they vest.  In July 2007, we initiated a stock option amendment program for employees, through a tender offer, to eliminate the adverse effect of Section 409A on certain employee stock options.  Employees can elect to replace stock options that were granted at less than fair market value and vest after December 2004 with new option grants with an exercise price equal to the fair market value on the revised measurement date of the option grant.  Employees will be compensated in cash in January 2008 for the increase in the exercise price for the option grants they elect to replace.  The tender offer expires on August 10, 2007 and we expect the charge to our results of operations in the three months ending September 30, 2007 will be approximately $0.3 million related to these stock option amendments.  In addition, we and our executive officers and directors agreed to amend certain outstanding stock options vesting after December 2004 which were determined to have been granted with

2

exercise prices below the fair market value of our common stock on the legal grant date.  In December 2006, we and our executive officers and directors agreed to amend each of these options to increase the option exercise price to the fair market value on the revised measurement date.  As these amendments involved no consideration to our executive officers and directors, we did not recognize any expense associated with these modifications.

In those instances where the approval date of the stock option grant could not be determined with certainty, or the terms of the option grant, including exercise price and number of shares were not final on the determined date of approval, we used a consistent methodology to determine the most likely measurement date of the option grant.  In determining a measurement date, we considered the date on which both approval of the stock option grant had been obtained and the terms of the option grant, including exercise price and number of shares, were final.  For each of our past stock option grants, we determined a measurement date using the following criteria:

1)For stock option grants approved at a meeting of either our Board of Directors or our Compensation Committee and evidenced by meeting minutes, the date of the meeting was determined to be the measurement date, provided the terms of the option grant, including exercise price and number of shares, were final on the date of the meeting.

2)For stock option grants approved by the members of our Compensation Committee through the process of signing unanimous written consents (“UWCs”), the following criteria were used to determine the measurement date of the grant:

a)If there was evidence of the date of signature for all of our Compensation Committee members, the date that the last Compensation Committee member signed the UWC was determined to be the measurement date, provided the terms of the option grant, including exercise price and number of shares, were final on that date;

b)If there was evidence of the date of signature for all of our Compensation Committee members, other than our Chief Executive Officer when he was a member of the Compensation Committee, the date that the last Compensation Committee member signed the UWC was determined to be the measurement date, provided the terms of the option grant, including exercise price and number of shares, were final on that date.

3)If there was no evidence that grants were approved through the process of signing UWCs, or there was no evidence as to the date of the signatures on the UWCs by our Compensation Committee members we considered email evidence to support the approval date.

We determined the measurement date based on the date of statements made in email correspondence that indicated that the stock option grant had been approved by all of the members of our Compensation Committee, provided the terms of the option grant, including exercise price and number of shares, were final on that date. We considered emails from our Compensation Committee members indicating the date of approval of the option grant and/or emails from our legal or human resources personnel indicating the date of approval of the option grant.

4)If there was a Form 3 or Form 4 filing associated with the option grant, we used the following criteria to determine the measurement date of the grant:

a)If an officer or director required to file reports under Section 16 of the Securities Exchange Act of 1934, as amended, filed a Form 3 or Form 4, we determined the measurement date to be the date that the Form 3 or Form 4 was filed;

b)If employees who were not Section 16 officers were included in the grant with Section 16 officers who filed a Form 3 or Form 4 and the number of shares attributable to employees who were not Section 16 officers were determined with finality at the time of the filing, we determined the measurement date to be the filing date of the Form 3 or Form 4 as it provided finality as to the exercise price.

5)If we did not have any corroborating evidence to indicate the date the stock option grant had been approved by all of the members of the Compensation Committee, and the filing of a Form 3 or Form 4 was not applicable, we looked for evidence that indicated the date on which the UWC was sent for signature, via email or fax, from us to our Compensation Committee members.  If this evidence existed, we analyzed the number of days it took for our Compensation Committee members to return the signed UWCs. A range of response time was determined by individual Compensation Committee member and used to develop a response time range for our Compensation Committee, as a group, during specific periods, as the composition of our Compensation Committee members changed over time.  Based on this analysis, four different ranges were determined. The range of response times from Compensation Committee members varied from a minimum of 1 to 2 days, for which there was one instance, to a maximum of 0 to 91 days, for which there were two instances. Based on the range of response time, we determined the measurement date to be the last day of the response time period, provided the option terms were final on this date, as this is the date we have determined is the date by which approval is most likely to have been obtained.

3

6)In instances where there was no evidence of the approval of the grant and/or finality of the option                  recipients and grant terms, we determined the measurement date based on the last date of entry for these stock options into our stock option tracking system. This date was deemed to be the most likely approval date as our policy and historical practice was to enter stock option grants into its stock option tracking system only after we believed that the option grants had been approved.

The restatement of prior year financial statements also includes adjustments for other errors that were not previously recorded because we believed the amount of any such errors, both individually and in the aggregate, were not material to our historical consolidated financial statements. Such errors primarily related to the recording of deferred income, classification of reserves for customer disputes, adjustments to accruals, and fixed asset depreciation.

The following is a summary of the effects on net income of the adjustments related to the above errors (in thousands):

Business

We are a leading provider of international communications services and a provider of retail prepaid calling services.  Our operations consist of our Voice-Over-Internet-Protocol (“VoIP”) trading business (“Trading”), in which we connect buyers and sellers of international telecommunications services, and our retail services business (“Retail”).  In the Trading business we receive voice traffic from buyers—originating carriers who are interconnected to our network via VoIP or traditional time division multiplexing (“TDM”) connections, and we route the traffic over the Internet to sellers—local carriers in the destination countries with whom we have established agreements to manage the completion or termination of the call.  We use proprietary, patent-pending technology to automate the selection of routes and termination partners based on a variety of performance, quality, and business metrics.  We offer this Trading service on a wholesale basis to carriers, telephony resellers and other service providers worldwide.  We have call termination agreements with local service providers in North America, Europe, Asia, the Middle East, Latin America, Africa and Australia.  Our Retail business was launched in late 2003, with the introduction of our retail prepaid calling cards which are marketed through distributors primarily to ethnic communities within major metropolitan markets in the U.S.  In late 2004, we launched a prepaid calling service, Pingo®, offered directly to consumers through an eCommerce web interface, which we have included in our Retail business segment.  Revenues from our Pingo® services have not been material in any period to date.

Presentation

The unaudited condensed consolidated financial statements presented herein have been prepared by us and, in the opinion of management, reflect all adjustments of a normal recurring nature necessary for a fair presentation. Interim results are not necessarily indicative of results for a full year.

The unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with generally accepted accounting principles have been omitted pursuant to those rules and regulations, but we believe that the disclosures are adequate to make the information presented not misleading.

Proposed Transaction with KPN B.V., a subsidiary of Royal KPN N.V.

On June 21, 2006, we entered into a Share Purchase and Sale Agreement with KPN B.V., formerly KPN Telecom B.V., (“KPN”), a subsidiary of Royal KPN N.V. and a private limited liability company organized under the laws of The Netherlands. Pursuant to the Share Purchase Agreement, we will acquire the shares of two subsidiaries of KPN (“KPN GCS”) and receive $55 million in cash from KPN in return for issuing to KPN that number of shares, of our common stock which, on a post issuance basis, represents 51% of the issued and outstanding shares of our common stock and outstanding in-the money stock options, as adjusted, and warrants.  KPN GCS encompasses KPN’s international wholesale voice business.

Upon the completion of the foregoing transactions, we will pay a dividend in the aggregate amount of $113 million, on a pro rata basis to those persons who are our shareholders of record on the date immediately prior to the date of the closing of the transactions contemplated by the Share Purchase Agreement. In addition, holders of outstanding warrants to purchase our common stock will be entitled to receive an amount in cash equal to the amount such holder would have received in connection with the dividend if such warrants had been exercised immediately prior to the closing of the transactions upon the future exercise of these warrants.  As of June 30, 2007, we had warrants to purchase 1.1 million shares of common stock outstanding.  In connection with our payment of the dividend, we will adjust the exercise price and number of shares to be issued upon exercise of our outstanding common stock options to preserve their value. The proposed transaction, which is subject to customary closing conditions, including regulatory approvals and the approval of our shareholders, is expected to be completed before the end of October 2007. On April 27, 2007, we announced that we and KPN had amended the Share Purchase Agreement to extend the outside date for completion of the transactions to October 31, 2007.  On August 2, 2007, we filed a preliminary proxy statement with the Securities and Exchange Commission to seek shareholder approval of these transactions.

Although we will be issuing shares of our common stock in acquiring KPN GCS, after the merger is completed, KPN will hold a majority of our outstanding common stock. Accordingly, for accounting and financial reporting purposes, we will be treated as the accounting acquiree. Under the purchase method of accounting, our tangible and identifiable intangible assets and liabilities will be, as of the date of the transaction, recorded at their fair value, including an amount for goodwill representing the difference between the deemed purchase price of iBasis and the fair value of our tangible and identifiable intangible net assets, and will be added to the historical assets and liabilities of KPN GCS.

We incurred merger related expenses of $1.5 million in the three and six months ended June 30, 2006, consisting primarily of investment banking advisory services, legal and accounting fees.  Merger related expenses in the first six months of 2007 were insignificant.    Such amounts have been expensed because we are the accounting acquiree.  Our revenues from our customer KPN for the three and six months ended June 30, 2007 and 2006 were not material.

(2)  Restatement of Condensed Consolidated Financial Statements

During the quarter ended September 30, 2006, subsequent to the issuance of the unaudited condensed consolidated financial statements for the three months ended June 30, 2006, our Board of Directors formed a Special Committee of independent directors to commence a voluntary investigation of our historical stock option grants and practices. Based upon the Special Committee’s review, the Audit Committee and our management determined that certain option grants during the periods from 1999 through 2006 were accounted for improperly, and, as such, stock-based compensation associated with certain grants was misstated for the years ended December 31, 2000 through 2005 and for each of the quarters in the six months ended June 30, 2006. The Special Committee identified errors and concluded that the measurement dates for determining the accounting treatment of certain historical stock option grants differed from the measurement dates used by us in preparing our financial statements.  In certain instances, the approval date of an option grant could not be determined with certainty.  In addition, the terms of an option grant, including exercise price and number of shares, may not have been final on the date of approval.  In those instances, we used other relevant available evidence to determine the measurement date of an option grant, based on the date by which option terms were final and approval of the option grant had most likely been obtained. The Special Committee also found that in a number of instances the date and exercise price of option grants had been determined with hindsight to provide a more favorable price for such grants.

For each of our past stock option grants, we have determined a measurement date using the following criteria:

1)For stock option grants approved at a meeting of either our Board of Directors or our Compensation Committee and evidenced by meeting minutes, the date of the meeting was determined to be the measurement date, provided the terms of the option grant, including exercise price and number of shares, were final on the date of the meeting.

2)For stock option grants approved by the members of our Compensation Committee through the process of signing Unanimous Written Consents (“UWCs”), the following criteria were used to determine the measurement date of the grant:

a)If there was evidence of the date of signature for all of our Compensation Committee members, the date that the last Compensation Committee member signed the UWC was determined to be the measurement date, provided the terms of the option grant, including exercise price and number of shares, were final on that date;

b)If there was evidence of the date of signature for all of our Compensation Committee members, other than our Chief Executive Officer when he was a member of our Compensation Committee, the date that the last Compensation Committee member signed the UWC was determined to be the measurement date, provided the terms of the option grant, including exercise price and number of shares, were final on that date.

3)If there was no evidence that grants were approved through the process of signing UWCs, or there was no evidence as to the date of the signatures on the UWCs by Compensation Committee members, we considered email evidence to support the approval date.

We determined the measurement date based on the date of statements made in email correspondence that indicated that the stock option grant had been approved by all of the members of our Compensation Committee, provided the terms of the option grant, including exercise price and number of shares, were final on that date. We considered emails from Compensation Committee members indicating the date of approval of the option grant and/or emails from our legal or human resources personnel indicating the date of approval of the option grant.

4)If there was a Form 3 or Form 4 filing associated with the option grant, we used the following criteria to determine the measurement date of the grant:

a)If an officer or director required to file reports under Section 16 of the Securities Exchange Act of 1934, as amended, filed a Form 3 or Form 4, we determined the measurement date to be the date that the Form 3 or Form 4 as filed;

b)If employees who were not Section 16 officers were included in the grant with Section 16 officers who filed a Form 3 or Form 4 and the number of shares attributable to employees who were not Section 16 officers were determined with finality at the time of the filing, we determined the measurement date to be the filing date of the Form 3 or Form 4 as it provided finality as to the exercise price

11

5)If we did not have any corroborating evidence to indicate the date the stock option grant had been approved by all of the members of our Compensation Committee, and the filing of a Form 3 or Form 4 was not applicable, we looked for evidence that indicated the date on which the UWC was sent for signature, via email or fax, from us to the Compensation Committee members. If this evidence existed, we analyzed the number of days it took for Compensation Committee members to return the signed UWCs. A range of response time was determined by individual Compensation Committee member and used to develop a response time range for the Compensation Committee, as a group, during specific periods, as the composition of the Compensation Committee members changed over time.  Based on this analysis, four different ranges were determined. The range of response times from Compensation Committee members varied from a minimum of 1 to 2 days, for which there was one instance, to a maximum of 0 to 91 days, for which there were two instances. Based on the range of response time, we determined the measurement date to be the last day of the response time period, provided the option terms were final on this date, as this is the date we have determined is the date by which approval is most likely to have been obtained.

6)In instances where there was no evidence of the approval of the grant and/or finality of the option recipients and grant terms, we determined the measurement date based on the last date of entry for these stock options into our stock option tracking system. This date was deemed to be the most likely approval date as our policy and historical practice was to enter stock option grants into our stock option tracking system only after we believed that the option grants had been approved.

As a result of the errors in determining measurement dates, we have also recorded payroll withholding tax related adjustments for certain options previously classified as Incentive Stock Option (ISO) grants under the Internal Revenue Service Code.  Such options were determined to have been granted with an exercise price below the fair market value of our common stock on the grant date determined. As a result, such options do not qualify for ISO tax treatment. The disqualification of ISO classification and the resulting conversion to a non-qualified option results in additional withholding taxes on exercise of such options.

In addition, as a result of the change in the measurement dates of certain stock option grants, certain options vesting subsequent to December 2004 result in non-qualified deferred compensation for purposes of Section 409A of the Code, and holders are subject to an excise tax on the value of the options in the year in which they vest.  In July 2007, we initiated a stock option amendment program for employees, through a tender offer, to eliminate the adverse effect of Section 409A on certain employee stock options.  Employees can elect to replace stock options that were granted at less than fair market value and vest after December 2004 with new option grants with an exercise price equal to the fair market value on the revised measurement date of the option grant.  Employees will be compensated in cash in January 2008 for the increase in the exercise price for the option grants they elect to replace.  The tender offer expires on August 10, 2007 and we expect the charge to our results of operations in the three months ended September 30, 2007 will be approximately $0.3 million related to these stock option amendments.  In addition, we and our executive officers and directors agreed to amend certain outstanding stock options vesting after December 2004 that were determined to have been granted with exercise prices below the fair market value of our common stock on the legal grant date.  In December, 2006, we and our executive officers and directors agreed to amend each of these options to increase the option exercise price to the fair market value on the revised measurement date.  As these amendments involved no consideration to our executive officers and directors, we did not recognize any expense associated with these modifications.

The restatement of prior year financial statements also includes adjustments for other errors that were not previously recorded because we believed the amount of any such errors, both individually and in the aggregate, were not material to our historical consolidated financial statements.  Such errors related to the recording of deferred income, classification of reserves for customer disputes, adjustments to accruals, and fixed asset depreciation

As a result of the above, we restated our consolidated financial statements as of December 31, 2005 and for the years ended December 31, 2005 and 2004 in our Annual Report on Form 10-K for the year ended December 31, 2006.   The restatement also affected years prior to 2004. We have restated our condensed consolidated statements of operations for the three and six months ended June 30, 2006 and our condensed consolidated statement of cash flows for the six months ended June 30, 2006 in this Quarterly Report on Form 10-Q. The stock-based compensation charges, including the aforementioned payroll withholding tax related adjustments, decreased our net income by $100,000 and $163,000 for the three and six months ended June 30, 2006, respectively.

The following tables set forth the effects of the restatement on our condensed consolidated statements of operations for the three and six months ended June 30, 2006 and our condensed consolidated statement of cash flows for the six months ended June 30, 2006

(3)  Net income (loss) per share

Basic net income per common share is determined by dividing net income by the weighted average common shares outstanding during the period.  Diluted net income per share is determined by dividing net income by weighted average common and dilutive common equivalent shares outstanding during the period.  Dilutive common shares consist of common stock issuable upon the exercise of stock options and warrants using the treasury method of Statement of Financial Accounting Standards No. 128, “Earnings Per Share”.  Basic and diluted net loss per share is determined by dividing net loss by the weighted average common shares outstanding during the period.

The following table summarizes common shares that have been excluded from the computation of diluted weighted average common shares for the periods presented:

(4)  Stock-Based Compensation

We issue stock options as an equity incentive to employees, non-employee directors and non-employee contractors under our 1997 Stock Incentive Plan (the “1997 Plan”).   The stock options we issue are typically for a fixed number of shares with an exercise price equal to the fair market value of our stock on the date of grant.  The employee stock option grants typically vest quarterly in equal installments over four years, provided that no options shall vest during the employees’ first year of employment, and have a term of ten years.   The 1997 Plan expires in August 2007, after which no additional stock options may be granted under this option plan.  On August 2, 2007 we filed a preliminary proxy statement with the Securities and Exchange Commission to seek shareholder approval of, among other things, the adoption of a new stock plan later this year.

Effective January 1, 2006, we adopted the provisions of Statement of Financial Accounting Standards 123R, “Share-Based Payment” (“SFAS 123R”), which require us to record compensation expense related to the fair value of our stock-based compensation awards.  We elected to use the modified prospective transition method as permitted under SFAS 123R.  Prior to January 1, 2006, we accounted for our stock-based compensation in accordance with Accounting Principles Board (“APB”) Opinion 25, “Accounting for Stock Issued to Employees,” and related interpretations.

The following table presents the employee stock-based compensation expense included in our unaudited condensed consolidated statements of operations.

	Three Months Ended June 30,				Six Months Ended June 30,

Provision for income taxes	—		—		—		—
Net stock-based compensation expense	$	508	$	683	$	1,342	$	963

The fair value of our stock option awards was estimated using the Black-Scholes model with the following weighted-average assumptions:

	Three Months Ended June 30,						Six Months Ended June 30,
	2007			2006			2007			2006
Risk free interest rate	4.75		%	4.88		%	4.69		%	4.69		%
Dividend yield	0.00		%	0.00		%	0.00		%	0.00		%
Expected life	6.25 years			6.25 years			6.25 years			6.25 years
Volatility	104		%	113		%	104		%	114		%
Fair value of options granted	$	8.26		$	5.32		$	8.21		$	5.54

The risk-free interest rate was based on the U.S. Treasury yield curve in effect at the time of grant.  The expected dividend yield of zero is based on the fact that we have never paid cash dividends and we have no current intention to pay cash dividends, other than the special dividend expected to be paid upon closing of the KPN transaction.  Our estimate of the expected life was determined using the simplified method allowed under SFAS 123R as our stock options qualify as “plain vanilla” options.  Our estimate of expected volatility is based on the historical volatility of our common stock over the period which approximates the expected life of the options.

No income tax benefit was realized from stock option exercises during the three and six months ended June 30, 2007 and 2006.

During the three months ended June 30, 2006, we issued a warrant to purchase 66,667 shares of our common stock to an investment banking firm with a fair value of $162,000 as partial payment for advisory services.

16

In the first quarter of 2007, the Compensation Committee of our Board of Directors approved a resolution that allowed us to modify the terms of stock option grants for certain individuals, covering an aggregate of approximately 100,000 shares, with exercise prices between $1.11 and $8.07 per share.  These modifications allowed employees, terminated on or after October 17, 2006, to exercise their vested stock options beyond the normal 90-day post-termination period provided under our 1997 Plan and their individual option agreements. We extended the exercise period of these options because we were unable, during our financial statement restatement process, to deliver registered shares of our common stock to such individuals in compliance with the applicable registration requirements of the Securities Act of 1933, as amended.  Absent the extension, these options would have expired prior to the employee having the opportunity to exercise, since the 90 day post-termination exercise period would have expired prior to our completion of the financial statement restatement process.

As a result of these modifications, we have recorded non-cash stock-based compensation charges, included in general and administrative expenses, totaling $0.1 million and $0.6 million in the three and six months ended June 30, 2007, respectively.  The charges relate primarily to modifications to option agreements that we subsequently classified as liabilities under EITF 00-19, “Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock” (“EITF 00-19”).   Under EITF 00-19, we are also required to report these option awards at their fair value as of each balance sheet date.  Any increase or decrease in this fair value is recorded in other expenses in our results of operations.   We recorded an additional charge of $0.1 million in the first quarter of 2007 related to the increase in the fair value of these option awards through March 31, 2007.   In the second quarter of 2007, the fair value of these option awards declined, primarily as a result of the market price of our common stock being lower at June 30, 2007 compared to March 31, 2007, which resulted in a reversal of $0.1 million in expense.

(5)  Short-term marketable investments

Our investments are classified as available-for-sale, carried at fair value and consist of securities that are readily convertible into cash, including government securities and commercial paper, with original maturities at the date of acquisition ranging from 90 days to one year.

Short-term marketable investments consist of:

	June 30, 2007					December 31, 2006
	(In thousands)
	Fair Value		Unrealized Gain (loss)			Fair Value		Unrealized Gain (Loss)
Government securities	$	—	$	—		$	1,986	$	—
Commercial paper, corporate bonds and certificates of deposit	9,990		(5		)	16,560		2
Total	$	9,990	$	(5	)	$	18,546	$	2

The net unrealized loss of $5,000 as of June 30, 2007 on our short-term marketable investments in government securities, commercial paper, corporate bonds and certificates of deposit was caused by interest rate increases.  Because we have the ability and intent to hold these investments until a recovery of fair value, which may be maturity, we do not consider these investments to be other-than-temporarily impaired at June 30, 2007 due to the short-term duration and the lack of severity of the impairment.  As of June 30, 2007 and December 31, 2006, the unrealized gain (loss) on our short-term marketable securities is a component of accumulated other comprehensive income (loss).

(6)  Business Segment Information

Our Trading business consists of international long distance services we provide using VoIP.  We offer these services on a wholesale basis through our worldwide network to carriers, telephony resellers and others around the world by operating through various service agreements with local service providers in North America, Europe, Asia, the Middle East, Latin America, Africa and Australia.

Our Retail business consists of our retail prepaid calling card services, and Pingo®, a prepaid calling service sold to consumers through an eCommerce interface.  To date, we have marketed our retail prepaid calling card services primarily to ethnic communities within major domestic markets through distributors.  Launched in the third quarter of 2004, revenue from our Pingo® services have not been material to date.

We use net revenue and gross profit, which is net revenue less data communications and telecommunications costs, as the basis for measuring profit or loss and making decisions on our Trading and Retail businesses.  We do not allocate our research and development expenses, selling and marketing expenses, general and administrative expenses, and depreciation and amortization between Trading and Retail.

Operating results, excluding interest income and expense, other income and expense, foreign exchange gains or losses, and income tax expense for our two business segments are as follows:

(7)  Accrued Restructuring Costs and Lease Termination Costs

In 2006, we negotiated the early termination of leased space for one of our locations in New York City which we no longer needed   and took a charge of $1.1 million for future monthly payment obligations through February 2011 under the lease termination agreement.

At June 30, 2007, accrued restructuring costs of $2.1 million consisted of $0.9 million remaining in future payment obligations relating to the terminated New York City facility lease and costs accrued for future lease obligations for certain vacant leased facilities, net of future sublease assumptions.  Payments of these restructuring costs will be made through February 2011.  During the three and six months ended June 30, 2007, we took an additional charge of $0.1 million and $0.2 million, respectively, as a result of a change in estimate relating to our future sublease assumptions on vacant leased facilities.

A summary of the accrued restructuring costs for the six months ended June 30, 2007 is as follows:

(In thousands)	Future Payment Obligation on Lease Termination			Contractual Lease Obligations Relating to Vacant Facilities			Total

(8)  Income Taxes

We adopted the provisions of Financial Accounting Standards Board (“FASB”) Interpretation No. 48, “Accounting for Uncertainty in Income Taxes-an interpretation of FASB Statement No. 109” (“FIN 48”), on January 1, 2007. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with FASB Statement 109, “Accounting for Income Taxes”, and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.

As a result of the adoption of FIN 48, we recognized a $409,000 liability for uncertain tax positions, which was accounted for as an increase to the accumulated deficit as of January 1, 2007 and an increase to other long-term liabilities. If this liability is ultimately not required, the reversal of this reserve would reduce the effective tax rate in the future. This liability relates to potential tax issues related to our international operations and included $307,000 for unrecognized tax liabilities and $102,000 for estimated accrued penalties and interest. We also increased the liability by $8,000 and $16,000 for interest expense incurred during the three and six months ended June 30, 2007, respectively.  There were no other changes in the liability during the three and six months ended June 30, 2007. We do not expect this liability to change significantly during the next 12 months. Our policy is to report penalties and tax-related interest expense as a component of income tax expense.

We are subject to U.S. federal income tax, as well as income tax in multiple state and foreign jurisdictions. As of June 30, 2007 and January 1, 2007, we were subject to examination in the U.S. federal tax jurisdiction for the 1997 to 2006 tax years and we were also subject to examination in most state and foreign jurisdictions for the 2000 to 2006 tax years.

As discussed in Note 10 to our consolidated financial statements in our 2006 Form 10-K, we have a valuation allowance against the full amount of our net deferred tax assets. We currently provide a valuation allowance against our deferred tax assets as it is more likely than not that some portion, or all of our deferred tax assets, will not be realized.

(9)  Line of Credit and Long-Term Debt

Long-term debt consists of the following:

	June 30, 2007		December 31, 2006
	(In thousands)
Capital lease obligations	$	1,478	$	2,217
Less-current portion	1,262		1,462
Long term debt, net of current portion	$	216	$	755

In May 2007, we amended certain financial covenants and extended the maturity date of our revolving line of credit with our bank from May 31, 2007 until July 30, 2007, and in July 2007, we further extended the maturity date of our revolving line of credit to October 31, 2007.  We also received a waiver of non-compliance of certain financial covenants from our bank for the period ending June 30, 2007.  We had issued outstanding letters of credit of $2.7 million at June 30, 2007 and December 31, 2006.  We had no other borrowings outstanding under our bank line of credit at June 30, 2007 and December 31, 2006.

(10)  Contingencies

Litigation

In addition to litigation that we have initiated or responded to in the ordinary course of business, we are currently party to the following potentially material legal proceedings:

Class Action Pursuant to 1999 Initial Public Offering

In 2001, we were served with several class action complaints that were filed in the United States District Court for the Southern District of New York against us and several of our officers, directors, and former officers and directors, as well as against the investment banking firms that underwrote our November 10, 1999 initial public offering of common stock and our March 9, 2000 secondary offering of common stock. The complaints were filed on behalf of a class of persons who purchased our common stock

20

between November 10, 1999 and December 6, 2000.

The complaints are similar to each other and to hundreds of other complaints filed against other issuers and their underwriters, and allege violations of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, primarily based on the assertion that there was undisclosed compensation received by our underwriters in connection with our public offerings and that there were understandings with customers to make purchases in the aftermarket. In September, 2001, the complaints were consolidated and allege that our prospectuses failed to disclose these arrangements. The consolidated complaint seeks an unspecified amount of monetary damages and other relief. In October 2002, the individual defendants were dismissed from the litigation by stipulation and without prejudice and subject to an agreement to toll the running of time-based defenses. In February 2003, the district court denied our motion to dismiss.

In June 2004, we and the individual defendants, as well as many other issuers named as defendants in the class action proceeding, entered into an agreement-in-principle to settle this matter, and this settlement was presented to the court. The district court granted a preliminary approval of the settlement in February 2005, subject to certain modifications to the proposed bar order, to which plaintiffs and issuers agreed. In August 2005, the district court issued a preliminary order further approving the modifications to the settlement, certifying the settlement classes and scheduled a fairness hearing, after notice to the class. The fairness hearing was held on April 24, 2006 and the motion for approval of the settlement is pending. Plaintiffs have continued to pursue their claims against the underwriters. The district court has established a procedure whereby six “focus” cases are being pursued initially and has certified a class of purchasers in those cases. The underwriters appealed the certification order in each of the six cases and in December 2006, the United States Court of Appeals for the Second Circuit reversed the certification orders. Since the pending settlement with the issuers involves parallel classes to those in the six focus cases, it is not expected that the district court will act favorably on the issuer settlement in its current form.

We anticipate additional settlement negotiations will occur, but there can be no assurance that those negotiations will result in a revised settlement. We believe that if this matter is not settled, we have meritorious defenses which we intend to vigorously defend.

We have received a letter, dated July 30, 2007, directed to our board of directors on behalf of an individual asserted to be a shareholder, demanding that the board of directors prosecute a claim against the Company’s IPO underwriters and certain of its officers, directors and principal shareholders, as identified in the IPO prospectus, for violations of Section 16(b) of the Securities Exchange Act of 1934.  The letter does not identify specific purchases and sales alleged to constitute violations of short-swing trading prohibitions of Section 16(b) and we expect to seek additional information sufficient to allow us to investigate the asserted violation.

We cannot estimate potential losses, if any, from these matters or whether, in light of our insurance coverage, any loss would be material to our financial condition, results of operations or cash flows.  As such, no amounts have been accrued as of June 30, 2007.

Class Action Regarding Prepaid Calling Card Claims

We have been named in a class action complaint, filed in the California State Court for the Western Division of Los Angeles on June 12, 2007, alleging violations of the California Consumers Legal Remedies Act: Nora Monday v. iBasis Inc. 6/12/2007 2:07-cv-03802 MMM  (Western Division - Los Angeles).  The putative class action plaintiff asserts that prepaid phone cards that we sell often expire without notice and without the consumer’s knowledge, charge rates that are frequently higher than stated in the uniform representations of the cards and include hidden charges.  We have not yet completed our review of the claims alleged and, at, this time, we are unable to estimate potential losses, if any, from this matter, or whether any loss would be material to our financial condition, results of operations or cash flows.  As such, no amounts have been accrued as of  June 30, 2007.

Actions Pursuant to Option Investigation

On December 21, 2006, two derivative actions naming us as a nominal defendant were filed in the United States District Court for the District of Massachusetts: David Shutvet, Derivatively on Behalf of iBasis, Inc., v. Ofer Gneezy et al., U.S.D.C. Civil Action No. 06-12276-DPW; and Victor Malozi, Derivatively on Behalf of iBasis, Inc., v. Ofer Gneezy et al., U.S.D.C. Civil Action No. 06-12277-DPW. The complaints in these two actions each name the same defendants: Ofer Gneezy, our President, Chief Executive Officer, Treasurer and Director; Gordon J. VanderBrug, our Executive Vice President, Assistant Secretary and Director; Richard G. Tennant, our Senior Vice President of Finance and Administration and Chief Financial Officer; Paul H. Floyd, our Senior Vice President of R&D, Engineering and Operations; Charles Corfield, Charles M. Skibo, W. Frank King, David Lee, and Robert H. Brumley, our Directors; Daniel Price, former Senior Vice President of Speech Solutions and our former Director; John G. Henson, Jr., our former Vice President, Engineering and Operations; Michael J. Hughes, our former Chief Financial Officer and former Vice President of Finance and Administration; Charles Giambalvo, our former Senior Vice President of Worldwide Sales; Jonathan D. Draluck, our former Vice President, Business Affairs, and former General Counsel and former Secretary; and John Jarve, Charles Houser, and Carl Redfield, our former Directors. The complaints allege that the defendants caused or allowed our “insiders” to backdate their stock-option grants, and caused or allowed us (i) to file materially false and misleading financial statements that materially understated our compensation expenses and materially overstated our quarterly and annual net income and earnings per share,and (ii) to make disclosures in our periodic filings and proxy statements that falsely portrayed our options as having been granted at exercise prices equal to the fair market value of our common stock on the date of the grant. The complaints also allege that certain defendants engaged in illegal insider selling of our common stock while in possession of undisclosed material adverse information. Based on these and other allegations, the complaints assert claims for: violation of Section 14(a) of the Exchange Act; disgorgement under the Sarbanes-Oxley Act of 2002; unjust enrichment; breach of fiduciary duty for approving improperly dated stock option grants to our executive officers; breach of fiduciary duties for insider selling and misappropriation of information; abuse of control; gross mismanagement; waste of corporate assets; an accounting; rescission of certain stock option contracts; and

21

constructive trust. The complaints seek the following relief: damages in favor of us for the individual defendants’ alleged wrongdoing; disgorgement of all bonuses or other incentive-based or equity-based compensation received by Mr. Gneezy and Mr. Tennant during any period for which we restated our financial results; a declaration that the Director defendants caused us to violate Section 14(a) of the Exchange Act; certain corporate governance reforms; an accounting of all undisclosed backdated stock option grants, cancellation of all unexercised grants, and revision of our financial statements; disgorgement of all profits obtained by the defendants from the allegedly backdated stock option grants and related equitable relief; and an award to the plaintiffs of their costs and disbursements for the action, including reasonable attorney’s fees and accountants’ and experts’ fees, costs and expenses.

On May 10, 2007, the United States District Court for the District of Massachusetts entered orders consolidating the above derivative actions under Civil Action No. 06-12276-DPW. On June 15, 2007, the Plaintiffs filed a consolidated complaint. Our response to the consolidated complaint is due on August 24, 2007, and we anticipate filing a motion to dismiss the consolidated complaint at that time.

We also announced on October 20, 2006 that we were contacted by the SEC as part of an informal inquiry and we further disclosed on March 29, 2007, on our Current Report on Form 8-K, that the SEC had notified us that we would be receiving a formal order of investigation relating to our stock option practices. On April 13, 2007, we received the formal order of investigation. The SEC investigation seeks documents and information from us relating to the grant of our options from 1999 to the present. We expect that the SEC will seek the testimony of individuals including certain of our executive officers and directors during the fourth quarter of 2007. We are cooperating fully with the SEC investigation that is ongoing. There is no assurance that other regulatory inquiries will not be commenced by other U.S. federal, state or other regulatory agencies.

We can not estimate the amount of losses, if any, from these matters, or whether any loss would be material to our financial condition, results of operations or cash flows.  As such, no amounts have been accrued as of June 30, 2007.

Regulatory Proceedings

On June 30, 2006, the Federal Communications Commission (“FCC”) issued an order requiring providers of prepaid calling cards that utilize Internet Protocol to contribute to the Universal Service Fund (“USF”) and pay access charges and other regulatory fees both in the future and for some prior period of time. In connection with our Retail business, we plan to absorb or pass along such future fees, to the extent permitted by law, which, based on current traffic mix, equal approximately 1.8% of revenue. We have filed an appeal of the retroactive aspect of the FCC Order with the United States Court of Appeals in Washington, D.C. In October 2006, we filed a motion to stay that aspect of the FCC Order pending the outcome of the appeal. On November 1, 2006, the Court deferred ruling on the stay request pending the FCC’s ruling on a similar stay motion pending before the agency. The agency denied the stay request on March 29, 2007. As of June 30, 2007, we estimate that the maximum potential retroactive USF charge relating to our Retail business prior to the third quarter of the year ended December 31, 2006 would be approximately $2.6 million.  If we are not successful with our appeal of the retroactive aspect of the FCC Order and are required to pay USF and other fees on a retroactive basis, we do not believe we would be able to recover these fees from our customers. As such, we would have to fund these fees up to the estimated maximum retroactive amount of $2.6 million.  As the amount of retroactive fees are not probable of being incurred, no amounts have been accrued as of June 30, 2007.

Other Matters

We are also party to suits for collection, related commercial disputes, claims by former employees, claims related to certain taxes, claims from carriers and foreign service partners over reconciliation of payments for circuits, Internet bandwidth and/or access to the public switched telephone network, and claims from estates of bankrupt companies alleging that we received preferential payments from such companies prior to their bankruptcy filings. Our employees have also been named in proceedings arising out of business activities in foreign countries. We intend to prosecute vigorously claims that we have brought and employ all available defenses in contesting claims against us, or our employees. Nevertheless, in deciding whether to pursue settlement, we will consider, among other factors, the substantial costs and the diversion of management’s attention and resources that would be required in litigation. In light of such costs, we have settled various and in some cases similar matters on what we believe have been favorable terms which did not have a material impact our financial position, results of operations, or cash flows. The results or failure of any suit may have a material adverse affect on our business.

We cannot estimate the amount of losses, if any, from these matters, or whether any loss would be material to our financial condition, results of operations or cash flows.  As such, no amounts have been accrued as of June 30, 2007.

Restatement of Consolidated Financial Statements, Summary of Historical Granting Process and Determination of Measurement Date and Related Proceedings

Restatement of Consolidated Financial Statements

In conjunction with the preparation and filing of our Form 10-Q for the three months ended June 30, 2006, we performed an internal review of our historical option grants from January 1, 2004 through May 2006 to discern any patterns relating to the timing and pricing of option grants. This internal review indicated that certain stock options grants were made at a relatively low price, compared to the price of our common stock in the days around the date of the stock option grant. In reviewing this information, our management did not believe that there would be a potential change in the measurement dates for these grants. On August 9, 2006, we filed our Form 10-Q for the quarter ended June 30, 2006.

At a meeting of our Board of Directors held on August 10, 2006, the status of the internal review was discussed. Subsequent to this meeting, our Executive Management and Board of Directors became aware, based on information provided to them by our former Vice President of Business Affairs and General Counsel, of email messages that he had written or received indicating that the date and exercise price of certain option grants may have been determined with hindsight.

On August 20, 2006, following review of the email messages and internal review, our Board of Directors formed a Special Committee of independent directors to commence a voluntary investigation of our historical stock option grants and practices. The Special Committee’s investigation considered evidence of all stock options grants for the period December 1999 through May 2006. The Special Committee was given broad authority to investigate and address our historical stock option grants and practices. The Special Committee was composed of two independent members of our Board of Directors, W. Frank King and Robert H. Brumley. The Special Committee retained the law firm of Goodwin Procter LLP as its independent outside counsel and Goodwin Procter LLP hired Law and Economics Consulting Group as independent accounting experts to aid in its investigation.

On October 17, 2006, the Special Committee concluded that the measurement dates for determining the accounting treatment of certain historical stock option grants differed from the measurement dates used by us in preparing our financial statements. Because the prices at the originally stated grant dates were, in certain cases, lower than the prices on the actual dates of the determination, we determined we should have recognized material amounts of stock-based compensation expense which were not accounted for in our previously issued financial statements. In certain instances, the approval date of an option grant could not be determined with certainty. In addition, the terms of an option grant, including exercise price and number of shares, may not have been final on the date of approval. In those instances, we used other relevant available evidence to determine the most likely measurement date for the option grant. The Special Committee also found that in a number of instances the date and exercise price of option grants had been determined with hindsight to provide a more favorable price for such grants.

In those instances where the approval date of the stock option grant could not be determined with certainty, or the terms of the option grant, including exercise price and number of shares were not final on the determined date of approval, we used a consistent methodology to determine the most likely measurement date of the option grant. In determining a measurement date, we considered the date by which both approval of the stock option grant had been obtained and the terms of the option grant, including exercise price and number of shares, were final.

Summary of Historical Granting Process and Determination of Measurement Dates

Pre IPO Approval Process

Since the Company’s inception in 1997 through November 1999, the month in which we went public, the majority of the stock option grants were approved in meetings of our Compensation Committee or Board of Directors.

Post IPO Approval Process

From December 1999, the month in which the first post IPO stock option grant was made, to February 2002, we obtained approval for the majority of option grants through the practice of sending a unanimous written consent (“UWC”) to our Compensation Committee that contained an “as of” grant date and exercise price, and a list of option recipients and shares awarded by recipient attached to the UWC. Beginning in May 2002, our former General Counsel’s practice changed to sending a UWC, with a blank grant date and blank exercise price, to our Compensation Committee members for approval, with a list of option recipients and shares to be awarded by recipient attached.

December 1999 to February 2002

Between December 1999 and February 2002, we had a total of twenty-three stock option grants. Of the twenty-three, we have evidence of seven option grants that were approved by UWCs that contained grant dates and exercise prices when the UWCs were sent to the Compensation Committee for approval. For eight other option grants approved by a UWC during this period, we do not have evidence of what the UWC contained when it was sent to the Compensation Committee for approval. Compensation Committee members generally returned their signed UWC signature pages to our former General Counsel. The final UWC was then completed by our former General Counsel, including attaching the previously obtained signature pages of the Compensation Committee members.

Of the remaining eight grants which occurred during the period from December 1999 to February 2002, one employee option grant was approved in a meeting of our Compensation Committee and one Director grant was approved in a meeting of our Board of Directors. The documentation of these meetings included the grant date, exercise price, option recipients, shares awarded and vesting terms. The remaining six option grants had no evidence or documentation supporting approval of the option grant, other than certain employee stock option agreements and the date of entry into our stock option tracking system.

During this period, the approved list of stock option grants, including the stock option grant date and exercise price, was then communicated by our former General Counsel to our Human Resources personnel for entry into our stock option tracking system. With respect to the grants in which the exercise price of the option was initially set forth in the UWC circulated to the Compensation Committee (provided the list of option recipients and shares awarded were final), we believe that on the date the Compensation Committee approved the option grant all of the terms of the option grant, including exercise price, were known with finality, as such terms were included in the UWC approved by the Compensation Committee and such terms were also consistent with the information that was ultimately entered into our stock option tracking system and communicated to employees.

May 2002 to May 2006

Between May 2002 and May 2006, we had a total of thirty-one stock option grants. Of the thirty one grants, we have evidence of seventeen option grants for which the UWC, when sent to our Compensation Committee, or Board of Directors for approval, did not contain a grant date and exercise price. Sometime after sending the UWCs out to Compensation Committee members for signatures, the date of the stock option grant and the stock option exercise price (equal to the closing price of our common stock on the stated grant date) were inserted into the final UWC by our former General Counsel. We have evidence for one grant in which the UWC, when sent to the Compensation Committee, contains a grant date and an exercise price. Compensation Committee members generally returned their signed UWC signature pages to our former General Counsel. For eight other option grants during this period, we did not have evidence of what the UWC contained when it was sent to the Compensation Committee for approval. Once signed UWCs were obtained the approved list of stock option grants, including the stock option grant date and exercise price, was then communicated by our former General Counsel to our Human Resources personnel for entry into our stock option tracking system.

Three other employee option grants were approved in meetings of our Compensation Committee and one non-employee Director grant was approved in a meeting of our Board of Directors. The documentation of these meetings included the grant date, exercise price, option recipients, shares awarded and vesting terms. In addition, there was one option grant during this period for which no evidence or documentation supporting approval of the option grant could be found, other than certain employee stock option agreements and the date of entry into our stock option tracking system.

For each of our past stock option grants, we determined a measurement date using the following criteria:

1)For stock option grants approved at a meeting of either our Board of Directors or our Compensation Committee and evidenced by meeting minutes, the date of the meeting was determined to be the measurement date, provided the terms of the option grant, including exercise price and number of shares, were final on the date of the meeting.

24

2)For stock option grants approved by the members of our Compensation Committee through the process of signing UWCs, the following criteria were used to determine the measurement date of the grant:

a)If there was evidence of the date of signature for all of our Compensation Committee members, the date that the last Compensation Committee member signed the UWC was determined to be the measurement date, provided the terms of the option grant, including exercise price and number of shares, were final on that date;

b)If there was evidence of the date of signature for all of our Compensation Committee members, other than our Chief Executive Officer when he was a member of the Compensation Committee, the date that the last Compensation Committee member signed the UWC was determined to be the measurement date, provided the terms of the option grant, including exercise price and number of shares, were final on that date.

3)If there was no evidence that grants were approved through the process of signing UWCs, or there was no evidence as to the date of the signatures on the UWCs by Compensation Committee members we considered email evidence to support the approval date.

We determined the measurement date based on the date of statements made in email correspondence that indicated that the stock option grant had been approved by all of the members of our Compensation Committee, provided the terms of the option grant, including exercise price and number of shares, were final on that date. We considered emails from Compensation Committee members indicating the date of approval of the option grant and/or emails from our legal or human resources personnel indicating the date of approval of the option grant.

4)If there was a Form 3 or Form 4 filing associated with the option grant, we used the following criteria to determine the measurement date of the grant:

a)If an officer or director required to file reports under Section 16 of the Securities Exchange Act of 1934, as amended, filed a Form 3 or Form 4, we determined the measurement date to be the date that the Form 3 or Form 4 was filed;

b)If employees who were not Section 16 officers were included in the grant with Section 16 officers who filed a Form 3 or Form 4 and the number of shares attributable to employees who were not Section 16 officers were determined with finality at the time of the filing, we determined the measurement date to be the filing date of the Form 3 or Form 4 as it provided finality as to the exercise price.

5)If we did not have any corroborating evidence to indicate the date the stock option grant had been approved by all of the members of our Compensation Committee, and the filing of a Form 3 or Form 4 was not applicable, we looked for evidence that indicated the date on which the UWC was sent for signature, via email or fax, from us to the Compensation Committee members. If this evidence existed, we analyzed the number of days it took for Compensation Committee members to return the signed UWCs. A range of response time was determined by individual Compensation Committee member and used to develop a response time range for the Compensation Committee, as a group, during specific periods, as the composition of the Compensation Committee members changed over time. Based on this analysis, four different ranges were determined. The range of response times from Compensation Committee members varied from a minimum of 1 to 2 days, for which there was one instance, to a maximum of 0 to 91 days, for which there were two instances. Based on the range of response time, we determined the measurement date to be the last day of the response time period, provided the option terms were final on this date, as we have determined that this is the date by which approval is most likely to have been obtained.

6)In instances where there was no evidence of the approval of the grant and/or finality of the option recipients and grant terms, we determined the measurement date based on the last date of entry for these stock options into our stock option tracking system. This date was deemed to be the most likely approval date as our policy and historical practice was to enter stock option grants into its stock option tracking system only after we believed that the option grants had been approved.

The measurement dates we determined for past stock option grants, using the criteria as described above, resulted in additional stock-based compensation of approximately $10.0 million for the years ended December 31, 2000 through December 31, 2005 and $57,000 and $92,000 for the three and six months ended June 30, 2006, respectively. The measurement date that we determined for one stock option grant dated May 25, 2000 resulted in approximately $7.7 million of the $10.0 million of additional stock-based compensation for years ended December 31, 2000 through December 31, 2005. For this particular grant, we could not determine with certainty the date of approval of such option grant. As a result, we determined the measurement date for the May 25, 2000 stock option grant to be the last day of the response period for Compensation Committee members to return their signed UWCs under criteria #5 as described above.

A summary of the additional stock-based compensation, by year, with the most significant stock option grants shown separately, is as follows:

Many of our measurement date conclusions are dependent on the facts and circumstances of each stock option grant and involved the application of significant management judgment. We believe the revised measurement dates we determined for option grants under criteria #4, #5 and #6 of our methodology, as described above, required the most judgment. As the revised measurement date may not be the actual measurement date, we performed several analyses to compare the impact on compensation of selecting measurement dates based upon the above described methodology to what would have resulted under different criteria for option grants where we determined the revised measurement date using criteria #4, #5 and #6 of our methodology.

In the first analysis, we considered that the measurement dates for eight stock option grants, where we had used the last day of a Compensation Committee member response period as the approval date (criteria #5), to be the date using both the lowest and highest stock price associated with a Compensation Committee approval period. Had we applied these alternate approaches, the first alternate measurement dates would have resulted in $4,533,000 in additional cumulative stock-based compensation charges being recorded from 2000 through June 30, 2006 for the alternative approach of using the highest stock price within the response period. The May 25, 2000 stock option grant accounts for approximately $4,470,000 of the additional $4,533,000 of stock-based compensation charges that would be recorded using the alternate approach of the highest stock price within the response period. The second alternate measurement dates would have resulted in $24,000 less in additional cumulative stock-based compensation charges being recorded from 2000 through June 30, 2006 for the alternative approach of using the lowest stock price within the response period. In addition, we also considered the impact on four grants where the approval response time as determined was later than the date such grants were entered into our option tracking system. In such cases, if the last date of entry into our option tracking system was used instead, the compensation charge would have been $28,000 less for the period.

In the second analysis, we considered the measurement dates for the twenty-five stock option grants, where we had used the last date of entry into our stock option tracking system as the measurement date (criteria #6), to be the date using both the lowest and highest stock price between the earliest possible approval date of the grant and the last date of entry into our stock option tracking system. Had we used these alternative measurement dates, this would have resulted in approximately $0.9 million in additional cumulative stock-based compensation using the highest stock price, and approximately $0.9 million less in additional cumulative stock-based compensation using the lowest stock price, being recorded from 2000 through June 30, 2006.

In the third analysis we considered the measurement dates for the nine stock option grants, where we used the dates of Form 3 or Form 4 filings as the measurement date (criteria #4), to be the date using both the lowest and highest stock price between the earliest possible date of approval of the grant and the date of the Form 3 or Form 4 filings. Had we used these alternative measurement dates, this would have resulted in $33,000 of additional cumulative stock-based compensation using the highest stock price, and approximately $0.3 million less in additional cumulative stock-based compensation using the lowest stock price, being recorded from 2000 through June 30, 2006.

We believe our methodology results in the most likely measurement dates for our stock option grants.

As a result of determining revised measurement dates, we have also recorded payroll withholding tax related adjustments for certain options previously classified as Incentive Stock Option (“ISO”) grants under the Internal Revenue Service Code of 1986, as amended (“the Code”). Such options were determined to have been granted with an exercise price below the fair market value of the Company’s stock on the revised measurement date. As a result such options do not qualify for ISO tax treatment. The disqualification of ISO classification and the resulting conversion to non-qualified stock option status results in additional withholding taxes on exercise of such options. We accordingly have a tax liability of $0.3 million and $0.5 million, as of June 30, 2007 and December 31, 2006, respectively, in connection with the disqualification of such ISO tax treatment.

In addition, as a result of the change in the measurement dates of certain stock option grants, certain options vesting subsequent to December 2004 result in non-qualified deferred compensation for purposes of Section 409A of the Code, and holders are subject to an excise tax on the value of the options in the year in which they vest.  In July 2007, we initiated a stock option amendment program for employees, through a tender offer, to eliminate the adverse effect of Section 409A on certain employee stock options.  Employees can elect to replace stock options that were granted at less than fair market value and vest after December 2004 with new option grants with an exercise price equal to the fair market value on the revised measurement date of the option grant.  Employees will be compensated in cash in January 2008 for the increase in the exercise price for the option grants they elect to replace.  The tender offer expires on August 10, 2007 and we expect the charge to our results of operations in the three months ending September 30, 2007 will

26

be approximately $0.3 million related to these stock option amendments.  In addition, we and our executive officers and directors agreed to amend certain outstanding stock options vesting after December 2004 which were determined to have been granted with exercise prices below the fair market value of our common stock on the legal grant date.  In December 2006, we and our executive officers and directors agreed to amend each of these options to increase the option exercise price to the fair market value on the revised measurement date.  As these amendments involved no consideration to our executive officers and directors, we did not recognize any expense associated with these modifications.

The restatement of prior year financial statements also includes adjustments for other errors that were not previously recorded because we believed the amount of any such errors, both individually and in the aggregate, were not material to our historical consolidated financial statements. Such errors primarily related to the recording of deferred income, classification of reserves for customer disputes, adjustments to accruals, and fixed asset depreciation.

The following is a summary of the effects on net income of the adjustments related to the above errors (in thousands):

As a result of the above, we restated our consolidated financial statements as of December 31, 2005 and for the years ended December 31, 2005 and 2004 in our Annual Report on Form 10-K for the year ended December 31, 2006.   The restatement also affected years prior to 2004.   We have restated our condensed consolidated statement of operations for the three and six months ended June 30, 2006 and our condensed consolidated statement of cash flows for the six months ended June 30, 2006 in this Quarterly Report on Form 10-Q.   The stock-based compensation charges, including the aforementioned payroll withholding tax related adjustments, decreased our net income by $100,000 and $163,000 for the three and six months ended June 30, 2006, respectively.

In accordance with the determinations of the Special Committee’s investigation, our Board of Directors terminated the employment of our former Vice President, Business Affairs and General Counsel and directed our Compensation Committee to adjust downward the compensation for fiscal year 2006 for both our Chief Executive Officer, Ofer Gneezy, and our Executive Vice President, Gordon VanderBrug, because their oversight of our stock option granting practices was inadequate. Additionally, the Special Committee recommended, and we have implemented, changes to our stock-based compensation transaction procedures and approval policies that require additional and more systematic authorization to ensure that all stock option transactions adhere to our approval process and stated policies, and that all such transactions are properly recorded in our stock administration systems and have appropriate supporting documentation.

The discussion and analysis set forth below in this Item 2 has been amended to reflect the restatement as described herein and in Note 2, “Restatement of Condensed Consolidated Financial Statements,” to the Notes to Condensed Consolidated Financial Statements. For this reason, the data set forth in this section may not be comparable to discussions and data in our previously filed Quarterly Reports on Form 10-Q.

Related Proceedings

We announced on October 20, 2006 that we were contacted by the SEC as part of an informal inquiry and we further disclosed on March 29, 2007, on our Current Report on Form 8-K, that the SEC had notified us that we would be receiving a formal order of investigation relating to our stock option practices. On April 13, 2007, we received the formal order of investigation. The SEC investigation seeks documents and information from us relating to the grant of our options from 1999 to the present. We expect that the SEC will seek the testimony of individuals including certain of our executive officers and directors during the fourth quarter of 2007. We are cooperating fully with the SEC investigation that is ongoing. There is no assurance that other regulatory inquiries will not be commenced by other U.S. federal, state or other regulatory agencies. We have incurred substantial expenses for legal, accounting, tax and other professional services in

27

connection with the Special Committee investigation, our internal review of our historical financial statements, the preparation and audit of the restated financial statements, the SEC investigation and related civil derivative litigation. These expenses were approximately $0.6 million and $1.5 million for the three and six months ended June 30, 2007, respectively.

Overview

We are a leading provider of international communications services and a provider of retail prepaid calling services. Our operations consist of our Voice-Over-Internet-Protocol (“VoIP”) trading business (“Trading”), in which we connect buyers and sellers of international telecommunications services, and our retail services business (“Retail”). In the Trading business we receive voice traffic from buyers—originating carriers who are interconnected to our network via VoIP or traditional time division multiplexing (‘TDM”) connections, and we route that traffic over the Internet to sellers—local service providers and carriers in the destination countries with whom we have established agreements to manage the completion or termination of the call. We use proprietary, patent-pending technology to automate the selection of routes and termination partners based on a variety of performance, quality, and business metrics. We offer this Trading service on a wholesale basis to carriers, consumer VoIP companies, telephony resellers and other service providers worldwide. We have call termination agreements with local service providers in North America, Europe, Asia, the Middle East, Latin America, Africa and Australia.

We launched our Retail business in late 2003, with the introduction of our retail prepaid calling cards, which are marketed through distributors primarily to ethnic communities within major metropolitan markets in the United States. In September 2004, we expanded our Retail business segment with Pingo®, a prepaid calling service that we offer and sell directly to consumers and business customers through an Internet website on a prepaid basis. Both the prepaid calling card business and Pingo leverage our existing international VoIP network and have the potential to deliver higher margins than are typically achieved in the Trading business. In addition, the retail prepaid calling card business typically has a faster cash collection cycle than the Trading business. Pingo is sold directly to consumers and business customers. To date, revenues from our Pingo services have not been material.

We continue to expand our market share in our Trading business by expanding our customer base and by introducing cost-effective solutions for our customers to interconnect with our network. Our Trading products include iBasis Directs™, which features our direct routes to more than 100 countries, which are our most cost-efficient routes. Designed for carrier customers with sophisticated Least Cost Routing capabilities, Directs offers our most competitive rates. We also offer our PremiumCertified® international routing product which features routes to more than 700 destinations that are actively monitored and managed to deliver a level of quality that is equal to or exceeds the highest industry benchmarks for retail quality. PremiumCertified is designed to take advantage of third-party or off-net routes to provide thorough worldwide coverage for customers, and enhances our ability to compete for retail international traffic from existing customers as well as from mobile operators and consumer VoIP providers.

In targeting the emerging consumer VoIP providers, we have expanded our DirectVoIPTM IP interconnection offering with DirectVoIP Broadband, which addresses requirements that are specific to the growing consumer VoIP market. DirectVoIP Broadband includes our transcoding solution, which enables us to provide greater interoperability among devices and voice applications, as well as deliver high quality service even over sub-optimal network connections. We have approximately 60 customers in the consumer VoIP market, including leaders among the emerging independent providers and cable operators, and we believe this market offers significant growth potential for us.

NASDAQ Listing

On July 11, 2007, we were notified by the Nasdaq Listing and Hearing Review Council that we were in compliance with all Nasdaq Marketplace Rules for continued listing on the Nasdaq Global Market and that the matter of our prior non-compliance with these rules was now closed.   Our non-compliance with the Nasdaq Marketplace Rules had resulted from our late filings with the Securities and Exchange Commission of our third quarter 2006 Form 10-Q, 2006 Form 10-K and first quarter 2007 Form 10-Q.  These late filings, which were completed and filed with the Securities and Exchange Commission in June 2007, were a result of the restatement of our prior financial statements.

Proposed Transaction with KPN B.V., a subsidiary of Royal KPN N.V.

On June 21, 2006, we entered into a Share Purchase and Sale Agreement with KPN B.V., formerly KPN Telecom B.V., (“KPN”), a subsidiary of Royal KPN N.V. and a private limited liability company organized under the laws of The Netherlands. Pursuant to the Share Purchase Agreement, we will acquire the shares of two subsidiaries of KPN (“KPN GCS”) and receive $55 million in cash from KPN in return for issuing to KPN that number of shares, of our common stock which, on a post issuance basis, represents 51% of the issued and outstanding shares of our common stock and outstanding in-the money stock options, as adjusted, and warrants.  KPN GCS encompasses KPN’s international wholesale voice business.

Upon the completion of the foregoing transactions, we will pay a dividend in the aggregate amount of $113 million, on a pro rata basis to those persons who are our shareholders of record on the date immediately prior to the date of the closing of the transactions contemplated by the Share Purchase Agreement. In addition, holders of outstanding warrants to purchase our common stock

28

will be entitled to receive an amount in cash equal to the amount such holder would have received in connection with the dividend if such warrants has been exercised prior to the closing of the transactions upon the future exercise of these warrants.  As of June 30, 2007, we had warrants to purchase 1.1 million shares of common stock outstanding.  In connection with our payment of the dividend, we will adjust the exercise price and number of shares to be issued upon exercise of our outstanding common stock options to preserve their value. The proposed transaction, which is subject to customary closing conditions, including regulatory approvals and the approval of our shareholders, is expected to be completed before the end of October 2007. On April 27, 2007, we announced that we and KPN had amended the Share Purchase Agreement to extend the outside date for completion of the transactions to October 31, 2007.  On August 2, 2007, we filed a preliminary proxy statement with the Securities and Exchange Commission to seek shareholder approval of these transactions.

Although we will be issuing shares of our common stock in acquiring KPN GCS, after the merger is completed, KPN will hold a majority of our outstanding common stock. Accordingly, for accounting and financial reporting purposes, we will be treated as the accounting acquiree. Under the purchase method of accounting, our tangible and intangible assets and liabilities will be, as of the date of the transaction, recorded at their fair value, including an amount for goodwill representing the difference between the deemed purchase price of iBasis and the fair value of our identifiable tangible and intangible net assets, and will be added to the historical assets and liabilities of KPN GCS.

We incurred merger related expenses of $1.5 million in the three and six months ended June 30, 2006, consisting primarily of investment banking advisory services, legal and accounting fees.  Merger related expenses in the first six months of 2007 were insignificant.  Such amounts have been expensed because we are the accounting acquiree.  Our revenues from KPN for the three and six months ended June 30, 2007 and 2006 were not material.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements.  The preparation of these financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires us to (i) make judgments, assumptions and estimates that affect the reported amounts of assets, liabilities, revenue and expenses and (ii) disclose contingent assets and liabilities.  We base our accounting estimates on historical experience and other factors that we consider reasonable under the circumstances.  However, actual results may differ from these estimates.  To the extent there are material differences between our estimates and the actual results, our future financial condition and results of operations will be affected.  Our critical accounting policies and estimates are described in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2006.  On January 1, 2007, we adopted the provisions of FIN 48, which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with FASB Statement 109, “Accounting for Income Taxes”, and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return.  There have been no other changes to these critical accounting policies and estimates for the three and six months ended June 30, 2007.

Three Months Ended June 30, 2007 Compared to June 30, 2006

Net revenue.   Our primary source of revenue is the fees that we charge customers for completing voice and fax calls over our network. Revenue is dependent on the volume of voice and fax traffic carried over our network and revenue from the sale of our prepaid calling services.  Our VoIP Trading revenue is dependent on the volume of voice and fax traffic carried over our network, which is measured in minutes.  We charge our customers fees, per minute of traffic, that are dependent on the length and destination of the call and recognize this revenue in the period in which the call is completed.  Our average revenue per minute (“ARPM”) is based upon our total net revenue divided by the number of minutes of traffic over our network for the applicable period.  Average revenue per minute is a key telecommunications industry financial measurement.  We believe this measurement is useful in understanding our financial performance, as well as industry trends.  Although the long distance telecommunications industry has been experiencing declining prices for a number of years, due to the effects of deregulation and increased competition, our average revenue per minute can fluctuate from period to period as a result of shifts in traffic over our network to higher priced, or lower priced, destinations.

Our total net revenue increased by approximately $28.3 million, or 22%, to $155.6 million in the second quarter of 2007 from $127.3 million in the second quarter of 2006.  Traffic carried over our network increased 31% to approximately 3.5 billion minutes in the second quarter of 2007 from 2.7 billion minutes in the second quarter of 2006.  Our ARPM was 4.4 cents per minute in the second quarter of 2007 compared to 4.7 cents per minute in the second quarter of 2006.  Trading revenue increased $25.3 million, or 25%, to $127.8 million in the second quarter of 2007 from $102.5 million in the second quarter of 2006.  We have continued to add Trading customers, ending the second quarter of 2007 with 636 customers compared to 471 customers at the end of the second quarter of 2006.  We have also continued to increase revenue from consumer VoIP customers, many of which use our PremiumCertified™ service.  We currently have approximately 70 consumer VoIP customers and revenue from these customers was 9% of total Trading revenue in the second quarter of 2007 compared to 10% in the second 2006. Retail revenue increased $3.0 million, or 12%, to $27.8 million in the second quarter of 2007 from $24.8 million in the second quarter of 2006.  The increase in Retail revenue reflects the launch of new calling card brands and the continued expansion of our distribution network.  Revenue from our Pingo® calling services, which is part of our Retail revenue, have not been material to date.

Sequentially, total net revenue increased approximately $9.8 million, or 4%, to $155.6 million in the second quarter of 2007 over $145.8 million in the first quarter of 2007.  Trading revenue of $127.8 million in the second quarter of 2007 increased $7.5 million, or 6%, over $120.3 million the first quarter of 2007 and Retail revenue of $27.8 million in the second quarter of 2007 increased $2.3 million, or 9%, from $25.5 million in the first quarter of 2007.   The increase in Retail revenue reflects a recovery from the decline in revenue we experienced in the second half of 2006, when we disengaged from doing business with one of our largest Retail calling card distributors due to delinquent payments.  Since late 2006, we have introduced new iBasis-branded calling cards and have strengthened our distribution network in a number of important markets.

Data communications and telecommunications costs.   Data communications and telecommunications costs are composed primarily of termination and circuit costs. Termination costs are paid to local service providers to terminate voice and fax calls received from our network. Termination costs are negotiated with the local service provider. Should competition cause a decrease in the prices we charge our customers and, as a result, a decrease in our profit margins, our contracts, in some cases, provide us with the flexibility to renegotiate the per-minute termination fees. Circuit costs include charges for Internet access at our Internet Central Offices, fees for the connections between our Internet Central Offices and our customers and/or service provider partners, facilities charges for overseas Internet access and phone lines to the primary telecommunications carriers in particular countries, and charges for the limited number of dedicated international private line circuits we use.  For our Retail calling services, these costs also include the cost of local and toll free access charges.  Our average cost per minute (“ACPM”) is based upon our total data communications and telecommunications costs divided by the number of minutes of traffic over our network for the applicable period.  We believe this measurement is useful in understanding our financial performance and industry trends.

Data communications and telecommunications expenses increased by $26.8 million, or 24%, to $137.8 million in the second quarter of 2007 from $111.0 million in the second quarter of 2006.  Our ACPM was 3.9 cents per minute in the second quarter of 2007 compared to 4.1 cents per minute in the second quarter of 2006. Data communications and telecommunications expenses were $113.7 million and $24.1 million for our Trading and Retail business segments, respectively, in the second quarter of 2007, compared to $90.4 million and $20.6 million for our Trading and Retail business segments, respectively, in the second quarter of 2006.  As a percentage of total net revenue, data communications and telecommunications expenses were 88.6% in the second quarter of 2007 compared to 87.2% in the second quarter of 2006.

Gross profit.   Trading gross profit was $14.0 million, or 11.0% of Trading revenue in the second quarter of 2007, compared to $12.1 million, or 11.8% of Trading revenue, in the second quarter of 2006.  Retail gross profit was $3.8 million, or 13.6% of Retail revenue in the second quarter of 2007, compared to $4.2 million, or 17.1% of Retail revenue, in the second quarter of 2006.  The lower Trading gross profit, as a percentage of Trading revenue, is due to an increase in traffic to lower margin destinations.  The lower Retail gross profit in the second quarter 2007 primarily reflects the issuance of a significant number of new prepaid calling cards, which initially have lower margins than our more established brands during the past six months.    In the second half of 2006, we disengaged doing business with one of our largest calling card distributors due to their default on payments to us.  The revenue we generated in the second quarter of 2006 on calling cards we sold through this distributor were primarily established brands which carried margins that were higher than our overall prepaid calling card portfolio.

Research and development expenses.   Research and development expenses include the expenses associated with developing, operating, supporting and expanding our international and domestic network, expenses for improving and operating our global network operations centers, salaries, and payroll taxes and benefits paid for employees directly involved in the development and operation of our global network operations centers and the rest of our network. Also included in this category are research and development expenses that consist primarily of expenses incurred in enhancing, developing, updating and supporting our network and our proprietary software applications.

Research and development expenses increased $0.4 million to $3.9 million in the second quarter of 2007, from $3.5 million in the second quarter of 2006.  The increase primarily reflects personnel additions and an increase in network hardware and software maintenance costs of $0.3 million.  Stock-based compensation included in research and development expenses were $0.1 million in the second quarter of 2007 and 2006.  As a percentage of net revenue, research and development expenses decreased to 2.5% in second quarter of 2007 from 2.8% in the second quarter of 2006.

Selling and marketing expenses.   Selling and marketing expenses include expenses relating to the salaries, payroll taxes, benefits and commissions that we pay for sales personnel and the expenses associated with the development and implementation of our promotion and marketing campaigns.

Selling and marketing expenses increased by $0.5 million to $4.8 million in the second quarter of 2007, from $4.3 million in the second quarter of 2006.  The increase in expenses, primarily related to our Retail business, largely relates to personnel additions and marketing and promotional expenditures, which increased $0.2 million year-to-year.  Stock-based compensation included in sales and marketing was $0.1 million in the second quarter of 2007 and 2006.  As a percentage of net revenue, selling and marketing expenses were 3.1% in the second quarter of 2007 and 3.3% in the second quarter of 2006.

General and administrative expenses.   General and administrative expenses include salaries, payroll taxes and benefits, and related costs for general corporate functions, including executive management, finance and administration, legal and regulatory, facilities, information technology and human resources.

General and administrative expenses increased $1.9 million to $7.1 million in the second quarter of 2007, from $5.2 million in the second quarter of 2006.  In the second quarter of 2007 we incurred $0.6 million in legal and accounting fees relating to the investigation of our stock option granting practices.  In addition, payroll-related costs increased approximately $0.5 million and fees for professional services, largely legal and audit fees, increased $0.6 million.  Total stock-based compensation and services included in

31

general and administrative expenses in the second quarter of 2007 was $0.3 million compared to $0.6 million in the second quarter of 2006.  As a percentage of net revenue, general and administrative expenses were 4.5% in the second quarter of 2007 and 4.1% in the second quarter of 2006.

In the first quarter of 2007, the Compensation Committee of our Board of Directors approved a resolution that allowed us to modify the terms of stock option grants for certain individuals, covering an aggregate of approximately 100,000 shares, with exercise prices between $1.11 and $8.07 per share.  These modifications allowed employees, terminated on or after October 17, 2006, to exercise their vested stock options beyond the normal 90-day post-termination period provided under our 1997 Plan and their individual option agreements. We extended the exercise period of these options because we were unable, during our financial statement restatement process, to deliver registered shares of our common stock to such individuals in compliance with the applicable registration requirements of the Securities Act of 1933, as amended.  Absent the extension, these options would have expired prior to the employee having the opportunity to exercise, since the 90 day post-termination exercise period would have expired prior to our completion of the financial statement restatement process.

As a result of these modifications, we have recorded non-cash stock-based compensation charges, included in general and administrative expenses, of  $0.1 million and $0.6 million in the three and six months ended June 30, 2007, respectively.  The charge of $0.6 million for the six months ended June 30, 2007 relates primarily to modifications to option agreements that we subsequently classified as liabilities under EITF 00-19, “Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock” (“EITF 00-19”).   Under EITF 00-19, we are also required to report these option awards at their fair value as of each balance sheet date.  We recorded an additional charge of $0.1 million in the first quarter of 2007, which is classified in other expenses, related to the increase in the fair value of these option awards through March 31, 2007.   In the second quarter of 2007, the fair value of these option awards declined, as a result of the market price of our common stock being lower at June 30, 2007 compared to March 31, 2007, which resulted in a reversal of $0.1 million in other expenses.

Depreciation and amortization expenses.   Depreciation and amortization expenses increased by $0.4 million to $2.2 million in the second quarter of 2007, from $1.8 million in the second quarter of 2006.  This increase was primarily due to depreciation relating to the addition of new capital equipment deployed into our network over the past twelve months. As a percentage of net revenue, depreciation and amortization expenses was 1.4% in the second quarter of 2007 and 2006.

Restructuring costs.   Restructuring costs of $0.1 million in the second quarter of 2007 relate to a change in estimate relating to our sublease assumptions associated with prior restructuring charges.

Merger related expenses.   Merger related expenses were $29,000 in the second quarter of 2007 and $1.5 million in  the second quarter of 2006 and relate to transaction costs for the pending transaction with KPN.   These transaction costs consist primarily of investment banking advisory services, legal and accounting fees.  These costs have been expensed as iBasis is not considered the accounting acquirer in this pending transaction and the transaction is being treated as a reverse acquisition.

Interest income.   Interest income was $0.6 million in the second quarter of 2007 compared to $0.5 million in the second quarter of 2006.  The increase reflects the income earned on our higher average year-to-year cash and short-term investment balances as well as the effect of higher short-term interest rates.

Interest expense.   Interest expense of $33,000 in the second quarter of 2007 and $95,000 in the second quarter of 2006 relates to capital lease obligations.

Other expenses, net.   Other expenses, net were $1,000 and $43,000 in the second quarter of 2007 and 2006, respectively.  Other expenses in the second quarter of 2007 were reduced by $0.1 million for the decrease in the fair value of option awards that were modified during Q1 of 2007 and are classified as liabilities under EITF 00-19.

Foreign exchange loss, net.   Foreign exchange loss was $46,000 in the second quarter of 2007, compared to a gain of $148,000 in the second quarter of 2006.  The foreign exchange loss in the second quarter of 2007 was primarily due to the effect of a weaker Euro relative to the U.S. dollar on our Euro-denominated accounts receivable.

Provision for income taxes.   The provision for income taxes of $20,000 in the second quarter of 2007 represents foreign income taxes on the earnings of our foreign subsidiaries and interest accrued on the liability for uncertain tax positions we recognized upon adoption of FIN 48 as of January 1, 2007.

Net income.   Net income was $0.1 million in the second quarter of 2007, or $0.00 per share, compared to net income of $0.3 million, or $0.01 per share, in the second quarter of 2006.  Net income for the second quarter of 2007 included $0.6 million in expenses related to the investigation of our past stock option granting practices.

Six Months Ended June 30, 2007 Compared to June 30, 2006

Net revenue.   Our total net revenue increased by approximately $63.3 million, or 27%, to $301.4 million in 2007 from $238.1 million in 2006.  Trading revenue increased $56.6 million, or 30%, to $248.1 million in 2007 from $191.5 million in 2006.  We have continued to add Trading customers, ending the second quarter of 2007 with 636 customers compared to 471 customers at the end of the second quarter of 2006.  We have also continued to increase revenue from consumer VoIP customers, many of which use our PremiumCertified™ service.  We currently have approximately 70 consumer VoIP customers and revenue from these customers was 9% of total Trading revenue in 2007 compared to 10% in 2006. Retail revenue increased $6.7 million, or 14%, to $53.3 million in 2007 from $46.6 million in 2006.  The increase in Retail revenue reflects the launch of new calling card brands and the continued expansion of our distribution network.  Revenue from our Pingo® calling services, which is part of our Retail revenue, has not been material to date.

Data communications and telecommunications costs.   Data communications and telecommunications expenses increased by $60.9 million, or 29%, to $268.3 million in 2007 from $207.4 million in 2006.  Data communications and telecommunications expenses were $222.1 million and $46.2 million for our Trading and Retail business segments, respectively, in 2007, compared to $168.8 million and $38.6 million for our Trading and Retail business segments, respectively, in 2006.  As a percentage of total net revenue, data communications and telecommunications expenses were 89.0% in 2007 compared to 87.1% in 2006.

Gross profit.   Trading gross profit was $26.0 million, or 10.5% of Trading revenue in 2007, compared to $22.7 million, or 11.9% of Trading revenue, in 2006.  Retail gross profit was $7.1 million, or 13.3% of Retail revenue in 2007, compared to $7.9 million, or 17.1% of Retail revenue, in 2006.  The lower Trading gross profit, as a percentage of Trading revenue, is due to an increase in traffic to lower margin destinations. The lower Retail gross profit in 2007 primarily reflects the issuance of a significant number of new prepaid calling cards, which initially have lower margins than our more established brands, during the past six months.    In the second half of 2006, we disengaged doing business with one of our largest calling card distributors due to their default on payments to us.  The revenue we generated in 2006 on calling cards we sold through this distributor were primarily established brands which carried margins that were higher than our overall prepaid calling card portfolio.

Research and development expenses.   Research and development expenses increased $0.8 million to $7.6 million in 2007, from $6.8 million in 2006.  The increase primarily reflects personnel additions and an increase in network hardware and software maintenance costs of $0.5 million.  Stock-based compensation included in research and development expenses were $0.2 million in 2007 and 2006.  As a percentage of net revenue, research and development expenses decreased to 2.5% in 2007 from 2.9% in second 2006.

Selling and marketing expenses.   Selling and marketing expenses increased by $1.4 million to $9.3 million in 2007, from $7.9 million in 2006.  The increase in expenses, primarily related to our Retail business, largely relates to personnel additions and marketing and promotional expenditures, which increased $0.6 million year-to-year.  Stock-based compensation included in sales and marketing was $0.2 million in 2007 and 2006.  As a percentage of net revenue, selling and marketing expenses were 3.1% in 2007 and 3.3% in 2006.

General and administrative expenses.   General and administrative expenses increased $4.2 million to $13.9 million in 2007, from $9.7 million in 2006.  In 2007, we incurred $1.5 million in legal and accounting fees relating to the investigation of our past stock option granting practices and we took a non-cash stock-based compensation charge of $0.6 million relating to the modification of certain stock options.  In addition, payroll-related costs increased approximately $0.7 million and fees for professional services, largely legal and audit fees, increased $1.0 million.  Total stock-based compensation and services included in general and administrative expenses in 2007 was $1.0 million compared to $0.5 million in 2006.  As a percentage of net revenue, general and administrative expenses were 4.6% in 2007 and 4.1% in 2006.

In the first quarter of 2007, the Compensation Committee of our Board of Directors approved a resolution that allowed us to modify the terms of stock option grants for certain individuals, covering an aggregate of approximately 100,000 shares, with exercise prices between $1.11 and $8.07 per share.  These modifications allowed employees, terminated on or after October 17, 2006, to exercise their vested stock options beyond the normal 90-day post-termination period provided under our 1997 Plan and their individual option agreements. We extended the exercise period of these options because we were unable, during our financial statement restatement process, to deliver registered shares of our common stock to such individuals in compliance with the applicable registration requirements of the Securities Act of 1933, as amended.  Absent the extension, these options would have expired prior to the employee having the opportunity to exercise, since the 90 day post-termination exercise period would have expired prior to our completion of the financial statement restatement process.

As a result of these modifications, we have recorded non-cash stock-based compensation charges, included in general and administrative expenses, totaling $0.6 million in 2007.  The charge of $0.6 million in 2007 relates primarily to modifications to option agreements that we subsequently classified as liabilities under EITF 00-19, “Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock” (“EITF 00-19”).   Under EITF 00-19, we are also required to report these option awards at their fair value as of each balance sheet date.  The increase to the fair value of these awards as of June 30, 2007 was $34,000.

33

Depreciation and amortization expenses.   Depreciation and amortization expenses increased by $0.8 million to $4.1 million in 2007, from $3.3 million in 2006.  This increase was primarily due to depreciation relating to the addition of new capital equipment deployed into our network over the past twelve months. As a percentage of net revenue, depreciation and amortization expenses was 1.4% in the second quarter of 2007 and 2006.

Restructuring costs.   Restructuring costs of $0.2 million in 2007 and 2006 relate to a change in estimate relating to our sublease assumptions associated with prior restructuring charges.

Merger related expenses.   Merger related expenses were $29,000 in 2007 and $1.5 million in 2006 and relate to transaction costs for the pending transaction with KPN.   These transaction costs consist primarily of investment banking advisory services, legal and accounting fees.  These costs have been expensed as iBasis is not considered the accounting acquirer in this pending transaction and the transaction is being treated as a reverse acquisition.

Interest income.   Interest income was $1.1 million in 2007 compared to $0.9 million in 2006.  The increase reflects the income earned on our higher average year-to-year cash and short-term investment balances as well as the effect of higher short-term interest rates.

Interest expense.   Interest expense of $0.1 million in 2007 and $0.2 million in 2006 relates to capital lease obligations.

Other expenses, net.   Other expenses, net were $0.2 million and $0.1 million in 2007 and 2006, respectively.  Other expenses in 2007 include $34,000 for the increase in the fair value of option awards, as of June 30, 2007, that were modified during the first quarter of 2007 and are classified as liabilities under EITF 00-19.

Foreign exchange loss, net.   Foreign exchange loss was $0.1 million in 2007, compared to a gain of $0.1 million in 2006.  The foreign exchange loss in 2007 was primarily due to the effect of a weaker Euro relative to the U.S. dollar on our Euro-denominated accounts receivable.

Provision for income taxes.   The provision for income taxes of $34,000 in 2007 represents foreign income taxes on the earnings of our foreign subsidiaries and interest accrued on the liability for uncertain tax positions we recognized upon adoption of FIN 48 as of January 1, 2007.  We did not have a U.S. federal or state tax provision in 2006, as we reversed approximately $0.7 million of our valuation allowance against our net deferred tax assets associated with significant net operating loss carry-forwards.

Net loss.   Net loss was $1.5 million in 2007, or $(0.04) per share, compared to net income of $1.9 million, or $0.06 per share, in 2006.  The 2007 net loss includes $1.5 million in expenses related to the investigation of our past stock option granting practices and $0.6 million in non-cash stock-based compensation expense related to the modification of certain stock options.

Liquidity and Capital Resources

Our principal capital and liquidity needs historically have related to the development of our network infrastructure, our sales and marketing activities, research and development expenses, and general capital needs. Our working capital needs have been met, in large part, from the net proceeds from our public and private offerings of common stock and issuances of convertible debt. In addition, we have also met our capital needs through capital equipment leases and other equipment financings.

Net cash provided by operating activities in 2007 was $6.5 million, compared to $13.0 million in 2006.  Net cash provided by operating activities in 2007 was largely a result of the net loss of $1.5 million, offset by non-cash charges for depreciation of $4.1 million, stock-based compensation of $1.3 million and a provision for doubtful accounts receivable of $0.7 million.  In addition, cash provided by changes in non-cash working capital was $1.6 million in 2007.  Net cash provided by operating activities in 2006 of $13.0 million was primarily the result of net income of $1.9 million and non-cash charges for depreciation of $3.4 million, stock-based compensation of $1.1 million, and a provision for doubtful accounts of $0.6 million.  In addition, cash provided by changes in non-cash working capital was $5.8 million in 2006.

Net cash provided by investing activities of $5.3 million in 2007 includes $3.2 million for capital expenditures, primarily for expansion of the iBasis Network.  In addition, we used $8.9 million for purchases of short-term marketable investments and received proceeds of $17.4 million from the maturities of short-term marketable investments.  Net cash used in investing activities in 2006 of $7.8 million consisted of $5.3 million for capital expenditures, $17.6 million for purchases of short-term marketable investments, partially offset by proceeds of $15.1 million from maturities of short-term marketable investments.

Net cash used in financing activities was $0.2 million in 2007 and relates to capital lease payments of $0.7 million, partially offset by proceeds of $0.5 million from the exercise of warrants into 0.1 million shares of common stock.  In addition, warrants for 0.6 million shares of common stock were exercised on a net share settlement basis.  Net cash used in financing activities in 2006 was $2.7 million and consisted of $2.3 million used for the repurchase of 0.4 million shares of our common stock, $0.8 million for capital lease

34

payments and proceeds from the exercise of employee stock options of $0.4 million.

In May 2007, we amended certain financial covenants and extended the maturity date of our revolving line of credit with our bank from May 31, 2007 until July 30, 2007.  We also received a waiver of non-compliance of certain financial covenants from our bank for the second quarter of 2007.  We had no borrowings under our $15.0 million bank line of credit at June 30, 2007 or December 31, 2006.  We had issued outstanding letters of credit of $2.7 million at June 30, 2007 and December 31, 2006, respectively.

On June 30, 2006, the Federal Communications Commission (“FCC”) issued an order requiring providers of prepaid calling cards that utilize Internet Protocol to contribute to the Universal Service Fund (“USF”) and pay access charges and other regulatory fees both in the future and for some prior period of time. In connection with our Retail business, we plan to absorb or pass along such future fees, to the extent permitted by law, which, based on current traffic mix, equal approximately 1.8% of revenue. We have filed an appeal of the retroactive aspect of the FCC Order with the United States Court of Appeals in Washington, D.C. In October 2006, we filed a motion to stay that aspect of the FCC Order pending the outcome of the appeal. On November 1, 2006, the Court deferred ruling on the stay request pending the FCC’s ruling on a similar stay motion pending before the agency. The agency denied the stay request on March 29, 2007. As of December 31, 2006, we estimate that the maximum potential retroactive USF charge relating to our Retail business prior to the third quarter of the year ended December 31, 2006 would be approximately $2.6 million. If we are not successful with our appeal of the retroactive aspect of the FCC Order and are required to pay USF and other fees on a retroactive basis, we do not believe we would be able to recover these fees from our customers. As such, we would have to fund these fees up to the estimated maximum retroactive amount of $2.6 million.  As the amount of retroactive fees are not probable of being incurred, no amounts have been accrued as of June 30, 2007.

We have incurred substantial expenses for legal, accounting, tax and other professional services in connection with the Special Committee investigation, our internal review of our historical financial statements, the preparation of the restated financial statements and the SEC investigation.  These expenses were approximately $1.5 million in the six months ended June 30, 2007.

We anticipate that the June 30, 2007 balance of $57.0 million in cash, cash equivalents and short-term marketable investments, together with cash flow generated from operations, will be sufficient to fund our operations and capital expenditures for at least the next twelve months.

Off-Balance Sheet Arrangements

Under accounting principles generally accepted in the U.S., certain obligations and commitments are not required to be included in the consolidated balance sheets and statements of operations. These obligations and commitments, while entered into in the normal course of business, may have a material impact on liquidity. We do not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.

Contractual Obligations

The following table summarizes our future contractual obligations as of June 30, 2007:

	Payment Due Dates
	Total		Less than 1 Year		1 to 2 Years		2 to 3 Years		3 to 5 Years		After 5 Years
	(In thousands)

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our primary market risk exposure is related to interest rates and foreign currency exchange rates. To date, we have not engaged in trading market risk sensitive instruments or purchasing hedging instruments, whether interest rate, foreign currency exchange, commodity price or equity price risk. We have not purchased options or entered into swaps or forward or futures contracts.

Our investments in commercial paper and debt instruments are subject to interest rate risk, but due to the short-term nature of these investments, changes in interest rates would not have a material impact on their value at June 30, 2007. Our primary interest rate risk is the risk on borrowings under our line of credit agreements, which are subject to interest rates based on the bank’s prime rate. A change in the applicable interest rates would also affect the rate at which we could borrow funds or finance equipment purchases.  Our capital lease obligations are fixed rate debt. A 10% change in interest rates would not have a material impact on interest expense associated with our line of credit agreement.

Although we conduct our business in various regions of the world, most of our revenues and costs are denominated in U.S. dollars with the remaining being primarily denominated in Euros or British pounds. Thus, we are exposed to foreign currency exchange rate fluctuations as the financial results and balances of our foreign subsidiaries are translated into U.S. dollars. As exchange rates vary, these results, when translated, may vary from expectations and may adversely impact our results of operations and financial condition. Accordingly, if the dollar weakens relative to foreign currencies, particularly the Euro or British Pound, our foreign currency denominated revenues and expenses would increase when stated in U.S. Dollars. Conversely, if the dollar strengthens, our foreign currency denominated revenues and expenses would decrease.  Based on our net revenue for the three months ended June 30, 2007, if the U.S. dollar had weakened against the Euro and British Pound by 10%, our net revenue would have increased approximately 3%.  Conversely, based on our net revenue for the three months ended June 30, 2007, if the U.S. dollar had strengthened against the Euro and British Pound by 10%, our net revenue would have decreased by approximately 3%.   The impact of a 10% change in the exchange rate between the U.S. dollar and the Euro or British Pound would not have a material effect on our foreign currency denominated operating expenses.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of June 30, 2007, we carried out an evaluation, under the supervision and with the participation of our management, including  our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a — 15(b) promulgated under the Exchange Act.  Based upon that evaluation, our management, including our Chief Executive Officer and our Chief Financial Officer, concluded that our disclosure controls and procedures are effective in ensuring that material information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, including ensuring that such material information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

Our management and Board of Directors continued the implementation of the following changes to our option granting process for the timing, approval and pricing of stock option grants in the quarter ended June 30, 2007 as detailed below:

·Our Commpensation Committee adopted a written charter in January 2007, taking into account similarly situated corporations and industry-wide best practices.

·Our Compensation Committee will arrange for counsel, in conjunction with outside third parties as deemed necessary, to provide training to management on stock option granting practices and accounting on at least a biannual basis, the initial training of our Board of Directors and executive management having been completed in the quarter ended June 30, 2007;

·Our Compensation Committee is required to do a self-assessment process and communicate the results to the full Board of Directors.

There have been no changes in our internal control over financial reporting during the quarter ended June 30, 2007 that have materially affected, or are reasonably like to materially affect, our internal control over financial reporting.

Additionally, management is investing in ongoing efforts to continuously improve the control environment and has committed considerable resources to the continuous improvement of the design, implementation, documentation, testing and monitoring of our internal controls.
