Note 1--Basis of Presentation

   The accompanying unaudited condensed consolidated financial statements of
IDT Corporation and subsidiaries (collectively "the Company") have been
prepared in accordance with generally accepted accounting principles for
interim financial information and with the instructions to Form 10-Q and
Article 10 of Regulation S-X. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all
adjustments (consisting of normal recurring accruals) considered necessary for
a fair presentation have been included. Operating results for the three and six
month periods ended January 31, 2000 are not necessarily indicative of the
results that may be expected for the year ending July 31, 2000. The balance
sheet at July 31, 1999 has been derived from the audited financial statements
at that date but does not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
For further information, please refer to the consolidated financial statements
and footnotes thereto included in the Company's Annual Report on Form 10-K as
amended for the year ended July 31, 1999, as filed with the Securities and
Exchange Commission.

   The Company has restated its financial statements for the three and six
month periods ended January 31, 1999 and 2000. The restatement resulted from
adjusting i) the timing of a gain recognized on the sale of stock by Net2Phone,
Inc., a majority owned subsidiary, and ii) the allocation of the purchase price
relating to the Company's acquisition of Interexchange, Inc.

   The aggregate effect of the aforementioned adjustments on the Company's
financial statements for the three months ended January 31, 1999 and January
31, 2000 is as follows:

Note 2--Recently Issued Accounting Standards

   In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities," which is required to be adopted in fiscal years
beginning after June 15, 2000. The Company believes that the adoption of this
standard will not have a material effect on the Company's consolidated results
of operations or financial position due to their limited use of derivative
instruments.

Note 5--Gain on Sale of Stock by Subsidiary

   On August 3, 1999, Net2Phone, Inc., a majority owned subsidiary, completed
an initial public offering of 6,210,000 shares of its common stock at a price
of $15 per share, resulting in net proceeds of approximately $85.3 million.

                                IDT CORPORATION

       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

completion of the initial public offering, 3,140,000 shares of Net2Phone Series
A Preferred Stock were converted into 9,420,000 shares of Net2Phone Class A
Stock. As a result of the initial public offering and concurrent conversion of
Series A Stock to Class A Stock, IDT's ownership percentage in Net2Phone
decreased from 90.0% to approximately 56.2%. This resulted in the Company
recording a gain on the sale of stock by a subsidiary of approximately $65.6
million. Such gain is included in other income, net for the six-months ended
January 31, 2000. Deferred taxes of $26.2 million have been provided on the
gain.

   In December 1999 (second quarter of fiscal 2000), the Company recorded a
$76.8 million pre-tax gain in connection with Net2Phone's secondary offering of
6.3 million shares of its common stock, at a price of $55.00 per share for net
proceeds to Net2Phone of approximately $177.4 million. Deferred taxes of
approximately $30.7 million have been provided for this gain.

   In addition, a $105.8 million pre-tax gain was recognized in December 1999
(second quarter of fiscal 2000) in connection with IDT's sale of 2,200,000
shares of common stock of Net2Phone in Net2Phone's secondary offering, at a
price of $55.00 per share for net proceeds of approximately $115.4 million.
IDT's ownership interest before and after this transaction and the secondary
(which occurred at the same time) was 56.24% and 47.97%, respectively.

Note 6--Legal Proceedings and Contingencies

   In January 1997, six former employees alleging employment discrimination
commenced a suit in New Jersey Superior Court, Bergen County. Howard S. Jonas,
the Chairman and Chief Executive Officer of the Company, has also been named as
a defendant in the action. The action claims that the Company has made hiring
and promotion decisions based upon the religious backgrounds of the relevant
individuals, in violation of federal and state law. The complaint seeks
compensatory and punitive damages in an unspecified amount and also seeks
statutory multiples of damages. All of the claims arising under federal law
were dismissed by the Court in New Jersey Superior Court, Bergen County,
leaving the plaintiffs with only the remedies available under state law.
Further, the Court granted the Company permission to file counterclaims against
all plaintiffs for the alleged unlawful taking of business records. The Company
filed such counterclaims in October 1998. Discovery is continuing and a trial
date has not been scheduled.

   In October 1999, Union Telecard Alliance, LLC ("Union"), a subsidiary of the
Company, commenced an action against DigiTEC 2000, Inc. ("DigiTEC") and TecNet,
Inc. ("TecNet") in the Supreme Court of the State of New York, County of New
York, alleging damages of approximately $725,000.00 based upon, among other
things, non-payment for prepaid calling cards. DigiTEC and TecNet have answered
the complaint, and DigiTEC has asserted a third party claim against the Company
seeking damages of $2.5 million dollars based upon the Company's alleged breach
of a settlement agreement between the Company and DigiTEC which had resolved a
prior litigation between those parties.

   In February 2000, IDT Europe B.V.B.A., a subsidiary of the Company, filed a
complaint against Tyco Group S.A.R.L. ("Tyco") and Tyco Submarine Systems, Ltd.
("TSSL") in the United States District Court in Newark, New Jersey, alleging
breach of implied covenant of good faith and fair dealing and breach of
contract for breaching a Memorandum of Understanding and Instruction to Proceed
entered into on November 9, 1999. The Company is seeking to enjoin and restrain
Tyco and TSSL from undertaking contrary business activity inconsistent with the
Memorandum of Understanding and Instruction to Proceed and is seeking
compensatory, consequential and punitive damages. The court has set March 24,
2000 as the date in which both Tyco and TSSL must file an answer.

       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


   In February 2000, Multi-Tech Systems, Inc. ("Multi-Tech") filed suit against
Net2Phone, Inc. ("Net2Phone"), a subsidiary of the Company, and other companies
in the United States Federal District Court in Minneapolis, Minnesota. In its
press release, Multi-Tech stated that "the defendant companies are infringing
because they are providing the end users with the software necessary to
simultaneously transmit voice and data on their computers in the form of making
a phone call over the Internet." Net2Phone intends to defend the lawsuit
vigorously. Net2Phone believes that the Multi-Tech claims are without merit.
However, should a judge issue an injunction against Net2Phone requiring that
Net2Phone cease distributing its software or providing its software-based
services, such an injunction could have an adverse effect on Net2Phone's
business.

   The Company is subject to other legal proceedings and claims, which have
arisen in the ordinary course of its business and have not been finally
adjudicated. Although there can be no assurances in this regard, in the opinion
of the Company's management, such proceedings, as well as the aforementioned
actions, will not have a material adverse effect on results of operations or
the financial condition of the Company.

Internet telephony services.

Six Months Ended January 31, 2000 Compared to Six Months Ended January 31, 1999

Results of Operations

   Revenue. Revenue increased 90.1%, from approximately $294.0 million for the
six months ended January 31, 1999 to approximately $558.9 million for the six
months ended January 31, 2000. Telecommunications revenues increased 93.8%,
from approximately $272.9 million for the six months ended January 31, 1999 to
approximately $529.1 million for the six months ended January 31, 2000.
Internet access revenues decreased 23.7%, from approximately $8.6 million for
the six months ended January 31, 1999 to approximately $6.5 million for the six
months ended January 31, 2000. Internet telephony revenues increased 86.7%,
from approximately $12.5 million for the six months ended January 31, 1999 to
approximately $23.3 million for the six months ended January 31, 2000.

   Telecommunications revenue increased primarily as a result of an 84.0%
increase in minutes of use from approximately 1.11 billion for the six months
ended January 31, 1999 to approximately 2.04 billion for the six months ended
January 31, 2000. The increase in minutes was primarily due to the addition of
wholesale carrier service clients, increased usage by existing clients, and
increased marketing of the Company's prepaid calling cards. The addition of
wholesale carrier services clients, increased use by existing clients and the
inclusion of $20 million in revenue for the quarter ended October 31, 1999
related to a one-time tariff opportunity resulted in an increase in wholesale
telecommunications revenues of 157.1%, from approximately $103.3 million for
the six months ended January 31, 1999 to approximately $265.5 million for the
six months ended January 31, 2000. As a percentage of telecommunications
revenue, wholesale telecommunications revenue increased from approximately
37.8% to approximately 50.2% period to period. Revenue from retail
telecommunications services increased 55.3%, from approximately $169.7 million
for the six months ended January 31, 1999 to approximately $263.6 million for
the six months ended January 31, 2000 as a result of increased marketing
efforts for the Company's prepaid calling cards. Prepaid calling card sales as
a percentage of retail telecommunication services revenue increased from 90.4%
for the six months ended January 31, 1999 to 94.2% for the six months ended
January 31, 2000. As a percentage of overall telecommunications revenue, retail
telecommunications revenue decreased from approximately 62.2% to approximately
49.8% period to period.

                                       11


   As a percentage of total revenue, Internet access revenue decreased from
approximately 2.9% for the six months ended January 31, 1999 to approximately
1.2% for the six months ended January 31, 2000. This was due primarily to
decreased revenue caused by the contribution of the majority of the Company's
dial-up subscribers to the joint venture formed with Terra Networks, S.A.
during the quarter ended October 31, 1999 as well as the substantial increase
in telecommunications revenue during the same period.

   Internet telephony revenue as a percentage of total revenue was 4.2% for
the six months ended January 31, 2000, representing a slight decrease from
4.3% for the six months ended January 31, 1999. The increase in Internet
telephony revenue, in dollar terms, was primarily due to an increase in billed
minutes of use resulting from increased marketing of the Company's Internet
telephony products and services.

   Direct Cost of Revenue. The Company's direct cost of revenue increased by
98.1%, from approximately $227.7 million for the six months ended January 31,
1999 to approximately $451.0 million for the six months ended January 31,
2000. As a percentage of total revenue, these costs increased from 77.4% for
the six months ended January 31, 1999 to 80.7% for the six months ended
January 31, 2000. The dollar increase is due primarily to increases in
underlying carrier and connectivity costs, as the Company's telecommunications
minutes of use, and associated revenues, grew substantially. As a percentage
of total revenue, the increase in direct costs reflects lower gross margins
associated with wholesale telecommunications services as compared to retail
telecommunications services as well as the lower gross margins related to
telecommunications revenue as compared with Internet access services.

   Selling, General and Administrative. Selling, general and administrative
costs increased 158.1%, from approximately $40.8 million for the six months
ended January 31, 1999 to approximately $105.3 million for the six months
ended January 31, 2000. As a percentage of total revenue, these costs
increased from 13.9% for the six months ended January 31, 1999 to 18.9% for
the six months ended January 31, 2000. This increase is due primarily to
increased international debit card distribution costs, increased sales and
marketing efforts for retail services, including prepaid calling cards and
domestic and international long distance and for Net2Phone, as well as
increased salaries, facilities costs and professional fees related to the
expansion of the Company's infrastructure to facilitate its rapid sales
growth. Also included in selling, general and administrative costs for the six
months ended January 31, 2000 is approximately $3.0 million in costs
associated with the Company's IDT Ventures division, which has several
innovative telecommunications and Internet related businesses under various
stages of development, and approximately $5.2 million of non-cash compensation
as a result of option grants made by our Net2Phone subsidiary.

   Depreciation and Amortization. Depreciation and amortization increased 22%,
from approximately $16.8 million for the six months ended January 31, 1999 to
approximately $20.4 million for the six months ended January 31, 2000. As a
percentage of revenue, these costs decreased from 5.7% for the six months
ended January 31, 1999 to 3.7% for the six months ended January 31, 2000.
These costs increased, in dollar terms, primarily as a result of amortization
of goodwill and other intangible assets that resulted from the Company's
acquisition of InterExchange Inc. in the fourth quarter of Fiscal 1998 and the
Company's higher fixed asset base during the six months ended January 31, 2000
as compared with the six months ended January 31, 1999, reflecting the
Company's efforts to expand its telecommunications network infrastructure and
other facilities. The Company anticipates that depreciation and amortization
costs will continue to increase as the Company continues to add to its asset
base, allowing it to implement its growth strategy.

   Income from Operations. The Company recorded a loss from operations of
approximately $17.8 million for the six months ended January 31, 2000, compared
to income from operations of approximately $8.8 million for the six months
ended January 31, 1999. Income from operations for the Company's
telecommunications business (after the effect of minority interests) declined
to approximately $5.7 million for the six months ended January 31, 2000 from
approximately $14.3 million for the six months ended January 31, 1999. As a
percentage of telecommunication revenue, income from operations for the
telecommunications business decreased to 2.8% for the six months ended January
31, 2000 from 5.9% for the six months ended January 31, 1999 due primarily

                                      12


to decreased margins in the carrier wholesale and retail telecommunications
businesses, and an increase in sales and marketing costs for retail
telecommunications services.

   Loss from operations for the Company's Internet access business increased to
approximately $7.2 million for the six months ended January 31, 2000 from
approximately $4.1 million for the six months ended January 31, 1999. The
increased loss is primarily due to the decrease in revenue caused by the
contribution of the majority of the Company's dial up subscribers to the joint
venture formed with Terra Networks, S.A. during the quarter ended October 31,
1999, lower gross margins and an increase in marketing expenses.

   Loss from operations of the Net2Phone subsidiary increased to approximately
$23.4 million for the six months ended January 31, 2000, compared to a loss of
approximately $3.7 million for the six months ended January 31, 1999. This
increase is due primarily to a substantial increase in selling, general and
administrative expenses incurred as Net2Phone expanded distribution
relationships, corporate infrastructure and human resources as well as the non-
cash compensation charge of $5.2 million described above.

   Other income. Included in other income for the six months ended January 31,
2000 is $142.3 million in gains recognized by the Company under Staff
Accounting Bulletin No. 51 in conjunction with Net2Phone's sale of shares in
its Initial Public Offering and concurrent conversion of Net2Phone's series A
stock to class A stock in August 1999 and its secondary offering in December
1999, and a realized gain of $105.8 million on the Company's sale of 2.2
million Net2Phone shares as part of Net2Phone's Secondary Offering.

   Income Taxes. The Company recorded income tax expense of approximately
$101.6 million for the six months ended January 31, 2000, compared to
approximately $3.1 million for the six months ended January 31, 1999. Income
tax benefit of approximately $1.3 million for the six months ended January 31,
2000, and approximately $0.5 million for the six months ended January 31, 1999
related to the tax deduction upon the exercise of stock options was recorded
directly into additional paid-in capital.

Three Months Ended January 31, 2000 Compared to Three Months Ended January 31,
1999

Results of Operations

   Revenue. Revenue increased 71.4%, from approximately $160.7 million for the
three months ended January 31, 1999 to approximately $275.5 million for the
three months ended January 31, 2000. Telecommunications revenue increased
74.6%, from approximately $149.2 million for the three months ended January 31,
1999 to approximately $260.6 million for the three months ended January 31,
2000. Internet access revenue decreased 30.4%, from approximately $4.3 million
for the three months ended January 31, 1999 to approximately $3.0 million for
the three months ended January 31, 2000. Internet telephony revenue increased
66.0%, from approximately $7.2 million for the three months ended January 31,
1999 to approximately $11.9 million for the three months ended January 31,
2000.

   Telecommunications revenue increased primarily as a result of a 57.8%
increase in minutes of use from approximately 638.2 million for the three
months ended January 31, 1999 to approximately 1.01 billion for the three
months ended January 31, 2000. The increase in minutes was primarily due to the
addition of wholesale carrier service clients, increased usage by existing
clients, and increased marketing of the Company's prepaid calling cards. The
addition of wholesale carrier services clients and increased use by existing
clients resulted in an increase in wholesale telecommunications revenues of
133.0%, from approximately $54.8 million for the three months ended January 31,
1999 to approximately $127.7 million for the three months ended January 31,
2000. As a percentage of telecommunications revenue, wholesale
telecommunications revenue increased from approximately 36.7% to approximately
49.0% period to period. Revenue from retail telecommunications services
increased 40.7%, from approximately $94.4 million for the three months ended
January 31, 1999 to approximately $132.9 million for the three months ended
January 31, 2000 as a result of increased marketing efforts for the Company's
prepaid calling cards. Prepaid calling card sales as a percentage of retail
telecommunication services revenue increased from 91.2% for the three months
ended January 31, 1999 to

                                       13


95.4% for the three months ended January 31, 2000. As a percentage of overall
telecommunications revenue, retail telecommunications revenue decreased from
approximately 63.3% for the three months ended January 31, 1999 to
approximately 51.0% for the three months ended January 31, 2000.

   As a percentage of total revenue, Internet access revenue decreased from
approximately 2.7% for the three months ended January 31, 1999 to approximately
1.1% for the three months ended January 31, 2000. This was due primarily to
decreased revenue caused by the contribution of the majority of the Company's
dial-up subscribers to the joint venture formed with Terra Networks, S.A.
during the quarter ended October 31, 1999 as well as the substantial increase
in telecommunications revenues during the same period.

   Internet telephony revenue as a percentage of total revenue amounted to 4.3%
for the three months ended January 31, 2000, a slight decrease from 4.5% for
the three months ended January 31, 1999. The increase in Internet telephony
revenue, in dollar terms, was primarily due to an increase in billed minutes of
use resulting from increased marketing of the Company's Internet telephony
products and services.

   Direct Cost of Revenue. The Company's direct cost of revenue increased by
74.4% from approximately $126.6 million for the three months ended January 31,
1999 to approximately $220.8 million for the three months ended January 31,
2000. As a percentage of total revenue, these costs increased from 78.8% for
the three months ended January 31, 1999 to 80.1% for the three months ended
January 31, 2000. The dollar increase is due primarily to increases in
underlying carrier and connectivity costs, as the Company's telecommunications
minutes of use, and associated revenues, grew substantially. As a percentage of
total revenue, the increase in direct costs reflects lower gross margins
associated with wholesale telecommunications services as compared to retail
telecommunications services as well as the lower gross margins related to
telecommunications revenue as compared with Internet access services.

   Selling, General and Administrative. Selling, general and administrative
costs increased 138.8%, from approximately $23.8 million for the three months
ended January 31, 1999 to approximately $56.7 million for the three months
ended January 31, 2000. As a percentage of total revenue, these costs increased
from 14.8% for the three months ended January 31, 1999 to 20.6% for the three
months ended January 31, 2000. This increase is due primarily to increased
international debit card distribution costs, increased sales and marketing
efforts for retail services, including prepaid calling cards and domestic and
international long distance and for Net2Phone, as well as increased salaries,
facilities costs and professional fees related to the expansion of the
Company's infrastructure to facilitate its rapid sales growth. Also included in
selling, general and administrative costs for the three months ended January
31, 2000 is approximately $3.0 million in costs associated with the Company's
IDT Ventures division, which has several innovative telecommunications and
internet related businesses under various stages of development, and
approximately $2.3 million of non-cash compensation as a result of option
grants made by our Net2Phone subsidiary.

   Depreciation and Amortization. Depreciation and amortization increased
18.4%, from approximately $8.8 million for the three months ended January 31,
1999 to approximately $10.5 million for the three months ended January 31,
2000. As a percentage of revenue, these costs decreased from 5.5% for the three
months ended January 31, 1999 to 3.8% for the three months ended January 31,
2000. These costs increased, in dollar terms, primarily as a result of
amortization of goodwill and other intangible assets that resulted from the
Company's acquisition of InterExchange Inc. in the fourth quarter of Fiscal
1998 and the Company's higher fixed asset base during the three months ended
January 31, 2000 as compared with the three months ended January 31, 1999,
reflecting the Company's efforts to expand its telecommunications network
infrastructure and other facilities. The Company anticipates that depreciation
and amortization costs will continue to increase as the Company continues to
add to its asset base, allowing it to implement its growth strategy.

   Income from Operations. The Company recorded a loss from operations of
approximately $12.4 million for the three months ended January 31, 2000,
compared to income from operations of approximately $1.6 million for the three
months ended January 31, 1999. Income from operations for the Company's
telecommunications business (after the effect of minority interests) increased
from approximately $5.2 million for the three months ended January 31, 1999 to
approximately $6.8 million for the three months ended

                                       14



January 31, 2000. As a percentage of telecommunication revenue, income from
operations for the telecommunications business decreased to 2.2% for the three
months ended January 31, 2000 from 5.3% for the three months ended January 31,
1999, due primarily to decreased margins in the carrier wholesale business, and
an increase in sales and marketing costs for retail telecommunications
services.

   Loss from operations for the Company's Internet access business increased to
approximately $3.6 million for the three months ended January 31, 2000 from
approximately $2.4 million for the three months ended January 31, 1999. The
increased loss is primarily due to the decrease in revenue caused by the
contribution of the majority of the Company's dial up subscribers to the joint
venture formed with Terra Networks, S.A. during the quarter ended October 31,
1999 coupled with lower gross margins.

   Loss from operations of the Net2Phone subsidiary increased to approximately
$14.1 million for the three months ended January 31, 2000, compared to a loss
of approximately $1.8 million for the three months ended January 31, 1999. This
increase is due primarily to a substantial increase in selling, general and
administrative expenses incurred as Net2Phone expanded distribution
relationships, corporate infrastructure and human resources as well as the non-
cash compensation charge of $2.3 million described above.

   Other income. Included in other income for the three months ended January
31, 2000 is $76.8 million in gains recognized by the Company under Staff
Accounting Bulletin No. 51 in conjunction with Net2Phone's sale of shares in
its Secondary Offering in December 1999, and a realized gain of $105.8 million
on the Company's sale of 2.2 million Net2Phone shares as part of Net2Phone's
Secondary Offering.

   Income Taxes. The Company recorded income tax expense of approximately $74.9
million for the three months ended January 31, 2000, compared to approximately
$0.6 million for the three months ended January 31, 1999. Income tax benefit of
approximately $0.5 million for the three months ended January 31, 2000, and
approximately $0.2 million for the three months ended January 31, 1999 related
to the tax deduction upon the exercise of stock options was recorded directly
into additional paid-in capital.

   Extraordinary Item. The Company recorded an after-tax extraordinary loss of
approximately $3.0 million related to the extinguishment of debt during the
three months ended January 31, 2000.

Liquidity and Capital Resources

 General

   Historically, the Company has satisfied its cash requirements through a
combination of cash flow from operating activities, sales of equity and debt
securities and borrowings from third parties. Additionally, the Company,
including Net2Phone, received approximately $6.2 million upon the exercise of
stock options in the six months ended January 31, 2000.

   In May 1999, the Company entered into a credit agreement with a syndicate of
lenders whereby these institutions committed to provide a $160 million credit
facility that included term loans in an aggregate amount of up to $135 million
and revolving loans in an amount of up to $25 million and an additional
uncommitted amount of up to $100 million. The Company used the proceeds from
the initial borrowings under the credit facility of $108.1 million to purchase
more than 99% of its outstanding 8.75% Senior Notes due 2006, together with
accrued and unpaid interest, in connection with its tender offer for these
securities. During the quarter ended January 31, 2000, the Company paid off the
outstanding indebtedness under the facility of $108.1 million, plus fees and
accrued and unpaid interest.

   As of January 31, 2000, the Company had cash, cash equivalents and
marketable securities of approximately $316.5 million and working capital of
approximately $353.7 million. The Company generated negative cash flow from
operating activities of approximately $41.1 million during the six months ended
January 31, 2000, compared with cash flow from operating activities of
approximately $4.6 million during the

                                       15


six months ended January 31, 1999. The Company's cash flow from operations
varies significantly from quarter to quarter, depending upon the timing of
operating cash receipts and payments, especially accounts receivable and
accounts payable. Accounts receivable, accounts payable and accrued expenses
have increased from period to period as the Company's businesses have grown.

   The Company's capital expenditures were approximately $34.6 million for the
six months ended January 31, 2000, compared to approximately $22.2 million for
the six months ended January 31, 1999, as the Company expanded its
international and domestic telecommunications network infrastructure. The
Company financed a portion of its capital expenditures through capital leases
and notes payable.

   The Company experiences intense competition in its telecommunications
business. The long distance telecommunications industry has been characterized
by declines in both per-minute revenues and per-minute costs. In the past,
these factors have tended to generally offset each other. However, as per-
minute pricing continues to erode, gross margins could come under increasing
pressure. The Company's long term strategy involves terminating a larger
proportion of minutes on the Company's own network, thereby lowering costs and
preserving margins even in a weaker price environment. However, in the short
term, the demand for usage might outpace the rate of deployment of additional
network capacity. As such, there can be no assurance that the Company will be
able to maintain its gross margins at the current level, in the face of lower
per-minute revenues.

   IDT's European telecommunications operations continue to account for an
increasing proportion of overall telecommunications revenue. Recognizing the
significant opportunities offered by the rapidly evolving European
telecommunications market, the Company intends to expand its network in Europe
to further develop its operations in that region. Such expansion may initially
have a negative impact on the Company's gross margins over the next two to
three quarters.

   The Company will need to make significant capital expenditures in order to
expand its network capacity. If the Company is unable to raise sufficient
capital to meet its spending requirements, the Company's network expansion, and
the associated margin improvement, would be delayed.

Changes in Other Assets, Accounts Receivable, Allowance for Doubtful Accounts
and Deferred Revenue

   Other current assets increased from $36 million at July 31, 1999 to $66
million at January 31, 2000, due primarily to increases in contract deposits
and prepaid expenses at Net2Phone. The average age of the Company's accounts
receivable, as measured by number of days sales outstanding has been increasing
due to a significant increase in sales to more credit worthy customers.

   Due to the wide range of collection terms, future trends with respect to
days sales outstanding are generally dependent upon the proportion of total
sales made to carriers, who are often offered extended payment terms of up to
90 days, and prepaid calling distributors, who generally receive terms of up to
30 days. Therefore, the trends in days sales outstanding will depend, in large
part, on the mix of (wholesale) carrier versus retail (debit card distributor)
customers. In addition, as the Company is willing to extend longer payments
terms to credit-worthy customers, an increase in customers belonging to the
highest credit class, as a percentage to total customers, could also lead to an
increase in days sales outstanding. However, as the foregoing is difficult to
predict, it is not possible at this time to determine whether or not the recent
trend in days sales outstanding will continue.

   The allowance for doubtful accounts as a percentage of accounts receivable
decreased/increased, from 6.7% at July 31, 1999, to 6.1% at January 31, 2000.

   Deferred revenue as a percentage of total revenue varies from period to
period dependent upon the mix and the timing of revenue.

                                       16


Net2Phone Financings

   In May 1999, a group of strategic investors purchased from Net2Phone, in the
aggregate, 3,140,000 shares of Net2Phone Series A Preferred Stock convertible
into 9,420,000 shares of common stock and warrants to purchase up to 180,000
shares of Net2Phone common stock, for a net aggregate purchase price of
$29.9 million. Additionally, Net2Phone issued a warrant to purchase 92,400
shares of its common stock to Hambrecht & Quist as part of its fee as placement
agent with respect to this transaction.

   In August 1999, Net2Phone completed its Initial Public Offering of 6.2
million shares, receiving approximately $85.3 million in net proceeds. At that
time, the Series A Preferred Stock was converted into Class A Common Stock. The
Company recognized pre-tax gains of approximately $65.6 million as a result of
these transactions.

   In December 1999, Net2Phone completed a Secondary Offering of 6.3 million
shares, receiving approximately $177.9 million in net proceeds. As part of the
Secondary Offering, the Company sold 2.2 million Net2Phone shares, yielding
approximately $115.4 million in net proceeds. Subsequent to the sale of these
shares, the Company used approximately $108.1 million of the proceeds to pay
off the outstanding balance of its bank credit facility.

   In connection with Net2Phone's distribution and marketing agreement with
ICQ, a subsidiary of America Online, Net2Phone issued to America Online a
warrant to purchase up to 3% of Net2Phone's outstanding capital stock on a
fully-diluted basis. This warrant will vest in 1% increments upon the
achievement of each of three incremental thresholds of revenue generated under
the agreement during the first four years that the warrant is outstanding. The
exercise price under the terms of the warrant will be equal to the lesser of
$12.00 per share or $450 million divided by the number of Net2Phone's fully-
diluted shares on the initial exercise date.

   The warrants are accounted for in accordance with the provisions of EITF 96-
18, "Accounting for Equity Investments that are Issued to Other than Employees
for Acquiring or in Conjunction with Selling Goods or Services." Due to the
uncertainty of reaching performance measures stipulated in the warrant
agreement, the Company has not recorded any expense relating to the issuance of
the warrant. Upon determination that the achievement of the revenue thresholds
is probable, the Company will value the warrant and expense it over the
remaining period until the performance criteria is met. The three revenue
thresholds are $10 million, $50 million and $75 million and the term of the
distribution and marketing agreement is four years. If the three incremental
thresholds had been met on January 31, 2000, the Company would have expensed
approximately $75.8 million.

   In November 1999, the warrant was amended to include the right to purchase
an additional 0.5% of Net2Phone's outstanding capital stock on a fully-diluted
basis at an exercise price of $60.46 per share upon the achievement of $100
million in revenue.

Acquisitions of In-Process Research & Development

   The Company's purchase of InterExchange, Inc. in April 1998 involved the
acquisition of two significant in-process research and development projects
relating to switch technology. Neither one of these projects has been/has not
been successfully completed at this time, and both projects have been/have not
been terminated. Currently, the Company is/is not contemplating any additional
acquisitions of in-process research and development.

Other Sources and Uses of Resources

   The Company intends to, where appropriate, make strategic acquisitions to
increase its telecommunications customer base. The Company may also make
strategic acquisitions related to its Internet telephony business. From time to
time, the Company evaluates potential acquisitions of companies, technologies,
products and customer accounts that complement its businesses.

   The Company believes that, based upon its present business plan, the
Company's existing cash resources, expected cash flow from operating activities
and access to credit facilities will be sufficient to meet its currently
anticipated working capital and capital expenditure requirements for at least
the next twelve months. If the Company's growth exceeds current expectations or
if the Company acquires the business or assets of another company, or if the
Company's cash flow from operations after the end of such period is
insufficient to meet its working capital and capital expenditure requirements,
the Company will need to raise additional capital from equity or debt sources.
There can be no assurance that the Company will be able to raise such capital
on favorable terms or at all. If the Company is unable to obtain such
additional capital, the Company may be required to reduce the scope of its
anticipated expansion, which could have a material adverse effect on the
Company's business, financial condition or results of operations.

Year 2000

   Prior to January 1, 2000, the Company reviewed and evaluated the possible
effects of the Year 2000 issue upon its installed computer systems, network
systems and software applications. The Year 2000 issue involved the fact that
many computers and applications define dates by the last two digits of the year
and "00" would possibly not be properly recognized by such programs as the year
2000. The Company dedicated the time and resources it deemed appropriate to
address and correct potential Year 2000 problems.

   In response to the Year 2000 issue, the Company established a Year 2000
compliance committee (the "Committee") to eliminate any possible disruptions in
services and operations due to the date change in the Year 2000. The Committee
developed a plan to identify and repair any systems that may be affected by the
Year 2000. The plan consisted of (1) identifying and inventorying all systems;
(2) assessing and testing the systems for Year 2000 compliance; (3) modifying,
upgrading or replacing any non compliant systems; and (4) testing the corrected
systems to ensure compliance.

   The Committee implemented this plan throughout the company and, in addition
to reviewing its own systems, the Company initiated inquiries and submitted
requests to its third party vendors and service providers to obtain information
regarding their compliance with the Year 2000. Furthermore, as a result of the
Company's focus on the testing and remediation of its switching facilities, its
network operations through which it provides communications services to its
customers, were not disrupted by the Year 2000.

   Inventory, assessment, remediation and testing of software applications and
hardware systems, including network systems, was substantially completed. The
Company completed the modification, updating or replacement of any systems that
to its knowledge were not Year 2000 compliant in November 1999. Testing of the
corrected systems has been implemented and will continue on an ongoing basis
through October 2000 due to the date October 10, 2000, being the first
occurrence of a date requiring the use of eight digits to define the date.

   The Company is confident that its own network systems are Year 2000
compliant due to the nature and extent of the testing the Company conducted and
continues to implement on such systems.

European Currency Conversion

   In January 1999, a new currency called the "euro" was introduced in certain
Economic and Monetary Union ("EMU") countries. The EMU countries adopted the
euro as their common legal currency, and through January 1, 2002, both the
existing national currency of the respective EMU country and the euro will be
accepted as legal currency. Beginning in 2002, all EMU countries are expected
to operate with the euro as their single currency. Uncertainty exists as to the
effect the euro currency will have on the market for international
telecommunications services. Additionally, all of the final rules and
regulations have not yet been defined and finalized by the European Commission
with regard to the euro currency. IDT's management is still evaluating the
effect that the introduction of the euro will have on its business, but it does
not anticipate, based on information currently available, that the euro will
have a material adverse impact on the Company's operations and sales.
