ADC TELECOMMUNICATIONS, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Note 1 ACCOUNTING POLICIES: The information furnished in this report is
unaudited but reflects all adjustments which are, in the opinion
of management, necessary to a fair statement of the results for
the interim periods. The operating results for the six months
ended April 30, 1994 are not necessarily indicative of the
operating results to be expected for the full fiscal year. These
statements should be read in conjunction with the Company's most
recent Annual Report on Form 10-K.
Note 2 STOCK DIVIDEND: On May 26, 1993 the Company declared a two-for-
one stock split in the form of a 100% stock dividend, payable
June 28, 1993 to shareholders of record June 15, 1993. The
share and per share information in this report have been adjusted
to reflect the effect of the dividend.
Note 3 ACCOUNTING FOR INCOME TAXES: Effective November 1, 1993, the
Company adopted Statement of Financial Accounting Standards
(SFAS) No. 109, "Accounting for Income Taxes." Under SFAS No.
109, deferred tax assets and liabilities relating to differences
between the financial statement and tax basis of assets and
liabilities are determined using tax rates currently in effect
for the periods in which the differences are expected to reverse.
The adoption of SFAS No. 109 had no effect on net income for the
six months ended April 30, 1994, and there was no material
cumulative effect of the accounting change on years prior to
November 1, 1993.
Note 4 EXTRAORDINARY ITEM: The building that serves as headquarters for
Fibermux Corporation, a wholly owned subsidiary of the Company,
suffered damage as a result of the earthquake that struck Los
Angeles on January 17, 1994. The Company recorded estimated
damages of $1,450,000 (net of the related $850,000 tax benefit).
The facility repairs were completed and all operations resumed by
February 8, 1994.

-------- ----- -------- ----- -------- ----- -------- -----
-------- ----- -------- ----- -------- ----- -------- -----
</TABLE>
The three-month and six-month increases in net sales reflect increased
sales volume in all product groups and all ADC entities. Second quarter 1994
net sales of networking products include approximately $4 million of Fibermux
Corporation (Fibermux) shipments that the Company was not able to ship in first
quarter 1994 after the Fibermux facility sustained earthquake damage in
mid-January.
Net sales of fiber optic products represented 34.5% and 33.2% of total net
sales for the quarters ended April 30, 1994 and 1993, respectively. For the six
months ended April 30, 1994 and 1993, net sales of fiber optic products
represented 33.5% and 33.6% of total net sales, respectively.
GROSS PROFIT: The second quarter 1994 gross profit percentage of 50.6% of
net sales was slightly lower than the 50.9% gross profit percentage for second
quarter 1993 primarily due to a less favorable product sales mix. For the
six-month periods ended April 30, 1994 and 1993, the gross profit percentages
were 50.5% of net sales and 51.0% of net sales, respectively. The 1994
year-to-date decrease primarily reflects a less favorable product sales mix.
OPERATING EXPENSES: Although selling expense was down as a percentage of
net sales in the quarter and six months ended April 30, 1994, marketing and
selling activities associated with new product introductions continued at a
higher level, resulting in a 14.2% increase in selling expenses during the
quarter and a 12.5% increase during the six months ended April 30, 1994.
Development and product engineering expenses, also reflecting new product
development efforts, increased 19.1% during the quarter and 17.3% during the six
months ended April 30, 1994, but decreased slightly as a percentage of net
sales.
8
<PAGE>
Company management continues its efforts to balance the cost of product
development with expense control and remains committed to minimizing the rate of
increase of such expenses, while addressing the major technological changes
underway in the telecommunications industry.
General and administrative expenses increased 44.5% during the quarter
ended and 28.5% during the six months ended April 30, 1994 primarily as a result
of increased compensation expenses, including increased incentive-based and
stock-based compensation. Company management anticipates that general and
administrative expenses as a percentage of net sales will decrease slightly
during the second half of the year.
OTHER INCOME (EXPENSE), NET: In the quarter and six months ended April 30,
1994, the net interest income (expense) category represented net interest income
on cash balances. (See Liquidity and Capital Resources below for a discussion of
borrowings.)
Other expense primarily represents amortization of the goodwill portions of
the Fibermux, Kentrox Industries, Inc. and American Lightwave Systems, Inc.
acquisition prices.
INCOME TAXES: The effective income tax rate was 37.0% for the quarters and
six months ended April 30, 1994 and 1993. In addition to the non-deductible
goodwill amortization amounts discussed above, the 37.0% rate reflects the
beneficial impact of tax credits.
Effective November 1, 1993, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes." Under SFAS
No. 109, deferred tax assets and liabilities relating to differences between the
financial statement and tax basis of assets and liabilities are determined using
tax rates currently in effect for the periods in which the differences are
expected to reverse.
The adoption of SFAS No. 109 had no effect on net income for the six months
ended April 30, 1994, and there was no material cumulative effect of the
accounting change on years prior to November 1, 1993.
EXTRAORDINARY ITEM: The extraordinary charge of $1,450,000, net of income
taxes, or $.05 per share, recorded in the quarter ended January 31, 1994,
represents the charge to clean up and repair the damage from the earthquake at
the Fibermux facility.
NET INCOME: For the quarter ended April 30, 1994, net income was
$10,085,000 or $.36 per share, 42.8% higher than the $7,064,000, or $.26 per
share net income for the quarter ended April 30, 1993. Net income of
$15,330,000, or $.55 per share for the six months ended
9
<PAGE>
April 30, 1994 reflected the extraordinary charge discussed above and compared
to net income of $12,324,000, or $.45 per share, for the six months ended April
30, 1993, reflecting a 24.4% increase over the comparable prior year period.
LIQUIDITY AND CAPITAL RESOURCES
Cash and cash equivalents, primarily short-term investments in commercial
paper with maturities of less than 90 days, increased $5,440,000 during the six
months ended April 30, 1994 and decreased $10,256,000 during the six months
ended April 30, 1993, respectively. The 1994 increase primarily reflects
increased cash provided from operating activities and the absence of debt
repayments, offset by the $7,087,000 contingent acquisition payment for ALS
which was accrued at October 31, 1993 and paid during the quarter ended January
31, 1994. ADC currently has no contingent acquisition purchase price
arrangements outstanding.
The Company may borrow up to $40 million under revolving credit agreements.
Borrowings under these agreements bear interest at floating short-term market
rates, can be repaid any time without penalty and can be converted to term loans
bearing interest principally at the prime rate, payable in annual installments
through December 2000. In May 1991, the Company's acquisition of Fibermux was
partially financed by borrowing the total $40 million. The full $40 million was
outstanding until April 1992, when the Company began repaying the debt. All
debt had been repaid by April 30, 1993. At April 30, 1994, $40 million of
borrowings under these agreements remained available to the Company, and its
long-term debt to total capitalization ratio was .2%. The Company's long-term
debt to total capitalization ratio was .4% at October 31, 1993.
Management expects that cash generated from operating activities plus
borrowings available under revolving credit agreements will be adequate to fund
operating requirements and property and equipment expenditures for the remainder
of 1994. However, management recognizes the dynamic nature of the
telecommunications industry, and the possibility that one or more of the
Company's product initiatives may achieve strong market acceptance during the
year. In such event, the Company would consider appropriate financing
alternatives. Total property and equipment additions for 1994 are expected to
be approximately $25 million.
