Exhibit 99.1

Pro-Forma Financial Statements

The following unaudited pro forma financial statements give effect to the
disposition of Airshow, Inc. to be accounted for as a discontinued operation in
accordance with FAS 144, "Accounting for the Impairment or Disposal of
Long-Lived Assets". On August 9, 2002, the Company consummated the sale of its
Airshow business for $152 million in cash, net of disposition proceeds of
approximately $8 million.

The pro forma financial statements also give effect to the Company's repurchase
of a portion of its outstanding Senior Subordinated Notes and a portion of its
outstanding Senior Secured Credit Facility term loan borrowings. The unaudited
pro forma condensed balance sheet assumes the disposition of Airshow, Inc. and
the repurchase of the Senior Subordinated Notes and Senior Credit Facility term
loan borrowings on June 30, 2002. Such pro forma information is based upon the
historical balance sheet data of Acterna Corporation as of that date. The
unaudited condensed statements of operations give effects to the disposition of
Airshow, Inc. and the repurchase of the Senior Subordinated Notes and Senior
Credit Facility term loan borrowings as if the transactions occurred on April 1,
1999. At the close of business on August 12, 2002, approximately $150 million
principal amount of the Senior Subordinated Notes had been validly tendered.
Approximately $106 million of the Notes will be retired.

These unaudited pro forma financial statements should be read in conjunction
with the historical consolidated financial statements and notes thereto of
Acterna Corporation for the year ended March 31, 2002.

occurred on April 1, 1999. Total non-recurring after tax gains of $165 million
on the sale of Airshow Inc. and the retirement of the Senior Subordinated Notes

million of Senior Secured Credit Facility term loan borrowings, a reduction of
$2.6 million in quarterly interest expense on $106 million of Senior

issuance costs. Reduction in the quarterly interest expense on term loan
borrowings was calculated based on the annual weighted-average interest rate of
7.0%. The reduction in the annual interest expense on the Senior Notes was
calculated based on the actual interest rate of 9.75%.

(b) To reflect $1.8 million income tax expense adjustment relating to $5.1

Note 1. The pro forma statements of operations give effect to the disposition of
Airshow, Inc. and the retirement of a portion of Senior Secured Credit Facility
term loan borrowings and Senior Subordinated Notes as if the transactions
occurred on April 1, 1999.
Total non-recurring after tax gains of $165 million on the sale of Airshow Inc.
and the retirement of the Senior Subordinated Notes have not been included in
the pro forma statements of operations but will be reflected in the historical
statement of operations in the period when the transactions are consummated. The
results of operations of Airshow, Inc. have been removed from the pro forma
statements of operations. The above pro forma statements of operations give
effect to the following pro forma adjustments necessary to reflect the
disposition and the repayment of debt from the proceeds of the disposition:

(a) To reflect a reduction of $8.6 million in annual interest expense on $129
million of Senior Secured Credit Facility term loan borrowings, a reduction of
$10.4 million in annual interest expense on $106 million of Senior Subordinated
Notes, and a $.9 million reduction in amortization of deferred debt issuance
costs. Reduction in the annual interest expense on term loan borrowings was
calculated based on the annual weighted-average interest rate of 6.7%. The
reduction in the annual interest expense on the Senior Notes was calculated
based on the actual interest rate of 9.75%.

(b) No income tax adjustment is required.



                                                                    Exhibit 99.1

Note 1. The pro forma statements of operations give effect to the disposition of
Airshow, Inc. and the retirement of a portion of Senior Secured Credit Facility
term loan borrowings and Senior Subordinated Notes as if the transactions
occurred on April 1, 1999.
Total non-recurring after tax gains of $165 million on the sale of Airshow Inc.
and the retirement of the Senior Subordinated Notes have not been included in
the pro forma statements of operations but will be reflected in the historical
statement of operations in the period when the transactions are consummated. The
results of operations of Airshow, Inc. have been removed from the pro forma
statements of operations. The above pro forma statements of operations give
effect to the following pro forma adjustments necessary to reflect the
disposition and the repayment of debt from the proceeds of the disposition:

(a) To reflect a reduction of $10.1 million in annual interest expense on $129
million of Senior Secured Credit Facility term loan borrowings, a reduction of
$10.4 million in annual interest expense on $106 million of Senior Subordinated
Notes, and a $.9 million reduction in amortization of deferred debt issuance
costs. Reduction in the annual interest expense on term loan borrowings was
calculated based on the annual weighted-average interest rate of 7.85%. The
reduction in the annual interest expense on the Senior Subordinated Notes was
calculated based on the actual interest rate of 9.75%.

(b) To reflect $8.0 million income tax expense adjustment relating to $21.4
million interest expense reduction.
