ESCO ELECTRONICS CORPORATION AND SUBSIDIARIES Notes to Condensed Consolidated Financial Statements (Unaudited) 1. Basis of Presentation The accompanying condensed consolidated financial statements, in the opinion of management, include all adjustments, consisting only of normal recurring accruals, necessary for a fair presentation of the results for the interim periods presented. The condensed consolidated financial statements are presented in accordance with the requirements of Form 10-Q and consequently do not include all the disclosures required by generally accepted accounting principles. For further information refer to the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended September 30, 1997. Certain prior year amounts have been reclassified to conform with the fiscal 1998 presentation. The results for the three and nine month periods ended June 30, 1998 are not necessarily indicative of the results for the entire 1998 fiscal year. 2. Earnings Per Share Basic earnings per share is calculated using the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated using the weighted average number of common shares outstanding during the period plus shares issuable upon the assumed exercise of dilutive common share options and performance shares by using the treasury stock method. The number of shares used in the calculation of earnings per share for each period presented is as follows (in thousands): Three Months Ended Nine Months ended June 30, June 30, -------- -------- 1998 1997 1998 1997 ---- ---- ---- ---- Weighted Average Shares Outstanding - Basic 11,965 11,804 11,880 11,810 Dilutive Options and Performance Shares 534 415 535 424 ------ ------ ------ ------ Adjusted Shares - Diluted 12,499 12,219 12,415 12,234 ====== ====== ====== ======
Options to purchase 77,500 shares of common stock at approximately $18.00 - $19.22 per share and options to purchase 163,750 shares of common stock at $12.38 were outstanding during the nine month periods ended June 30, 1998 and June 30, 1997, respectively, but were not included in the respective computations of diluted EPS because the options exercise price was greater than the average market price of the common shares. These options expire in 2007 and 2008. Approximately 113,000 and 334,000 performance shares were outstanding but unearned at June 30, 1998, and 1997, respectively, and therefore, were not included in the respective computations of diluted EPS. The unearned performance shares expire in 2001. 3. Inventories Inventories consist of the following (dollars in thousands): June 30, September 30, 1998 1997 ---- ---- Finished Goods $ 8,670 8,542 Work in process, including long-term contracts 64,177 22,971 Raw materials 15,703 13,597 ------ ------ Total inventories $88,550 45,110 ====== ======
Under the contractual arrangements by which progress payments are received, the U.S. Government has a security interest in the inventories associated with specific contracts. Inventories are net of progress payment receipts of $3.1 million and $3.2 million at June 30, 1998 and September 30, 1997, respectively. The increase in inventories (work-in-process) is primarily related to the TUNNER program at SEI, as well as a normal inventory build-up at the other operating units necessary to satisfy the increased sales requirements for the remaining three months of fiscal 1998. Item 2. Management's Discussion and Analysis of Results of Operations and Financial Condition Results of Operations - Three months ended June 30, 1998 compared with three months ended June 30, 1997. Net sales of $98.2 million for the third quarter of fiscal 1998 decreased $11.1 million (10.2%) from net sales of $109.3 million for the third quarter of fiscal 1997. The sales decrease in the current quarter reflects lower defense sales at Systems & Electronics Inc. (SEI) resulting from the timing of the receipt of defense orders. This decrease was partially offset by additional commercial sales at PTI and Filtertek. Commercial sales were $55.1 million (56.1%) and defense sales were $43.1 million (43.9%) for the third quarter of fiscal 1998, compared with commercial and defense sales of $56.5 million (51.7%) and $52.8 million (48.3%), respectively, in the third quarter of fiscal 1997. Commercial sales decreased ($1.4 million, net) in the third quarter of fiscal 1998 compared with the third quarter of fiscal 1997 due to lower U.S. Postal Service sales at SEI, partially offset by an increase in filtration/fluid flow products at PTI and Filtertek. Order backlog at June 30, 1998 was $285.3 million, compared with $253.4 million at March 31, 1998. During the fiscal 1998 third quarter, new orders aggregating $130.1 million were received, compared with $88.0 million (48% increase) in the third quarter of fiscal 1997. The most significant orders in the current period were for electric utility communication and automatic meter reading systems, filtration/fluid flow products, long-lead funding for the 60K/TUNNER aircraft loader program, U.S. Postal Service equipment, and electronic test equipment. The gross profit percentage was 26.1% in the third quarter of fiscal 1998 and 23.3% in the third quarter of fiscal 1997. The gross margin increased in the third quarter of fiscal 1998 due to an improved sales mix throughout the Company. Selling, general and administrative (SG&A) expenses for the third quarter of fiscal 1998 were $17.0 million, or 17.3% of net sales, compared with $17.1 million, or 15.6% of net sales, for the same period a year ago. The percentage increase is the result of the lower sales level in fiscal 1998. Interest expense increased to $2.0 million in fiscal 1998 from $1.9 million in fiscal 1997 as a result of higher average outstanding borrowings in the current period. A significant amount of the outstanding borrowings in both periods presented were incurred in conjunction with the 1997 acquisition of Filtertek. Other costs and expenses, net, were $1.1 million in the third quarter of fiscal 1998, consistent with the $1.1 million in the same period of fiscal 1997. The effective income tax rate in the third quarter of fiscal 1998 was 31.3% compared to 38.5% in the third quarter of fiscal 1997. The lower effective tax rate is primarily attributable to the earnings contributed from the Company's foreign operations. Results of Operations - Nine months ended June 30, 1998 compared with nine months ended June 30, 1997 Net sales of $262.3 million for the first nine months of fiscal 1998 decreased $4.8 million (1.8%) from net sales of $267.1 million for the first nine months of fiscal 1997. The decrease primarily reflects lower defense sales at SEI. This decrease was partially offset by additional commercial sales resulting from the Filtertek acquisition ($26.4 million net increase) and higher volume at EMC Test Systems and PTI. Commercial sales were $145.9 million (55.6%) and defense sales were $116.4 million (44.4%) for the first nine months of fiscal 1998, compared with commercial and defense sales of $122.1 million (45.7%) and $145 million, (54.3%) respectively, in the first nine months of fiscal 1997. The order backlog at June 30, 1998 was $285.3 million, compared with $228.2 million at September 30, 1997. During the first nine months of fiscal 1998, new orders aggregating $319.4 million were received, compared with $240.6 million (32.8% increase) in the first nine months of fiscal 1997. The most significant orders in the current period were for filtration/fluid flow products, electric utility communication and automatic meter reading systems, long-lead funding for the 60K/TUNNER aircraft loader program, M1000 tank transporters, airborne radar systems, and fire support mission equipment. The gross profit percentage was 27.5% in the first nine months of fiscal 1998 and 24.3% in the first nine months of fiscal 1997. The fiscal 1998 gross profit percentage increased from fiscal 1997 due to an improved sales mix throughout the Company. Selling, general and administrative expenses for the first nine months of fiscal 1998 were $49.8 million, or 19.0% of net sales, compared with $45.8 million or 17.1% of net sales, for the same period a year ago. The increase in fiscal 1998 SG&A expenses is primarily due to the inclusion of Filtertek for the entire period of fiscal 1998 as compared to a partial period of fiscal 1997 as the acquisition was completed February 7, 1997. Interest expense increased to $5.7 million from $3.4 million as a result of higher average outstanding borrowings in fiscal 1998 compared to fiscal 1997. A significant amount of the outstanding borrowings in 1998 were incurred in conjunction with the February 1997 acquisition of Filtertek. Other costs and expenses, net, were $2.8 million in the first nine months of fiscal 1998, consistent with the $2.9 million in the same period of fiscal 1997. The effective income tax rate in the first nine months of fiscal 1998 was 31.0% compared with 35.3% for the first nine months of fiscal 1997. The lower effective tax rate for the first nine months of fiscal 1998 is attributable to the earnings contributed from the Company's Puerto Rican and other foreign operations, and refunds received relating to the resolutions of state and local tax matters. Management estimates the annual effective tax rate for fiscal 1998 to be approximately 31%. Financial Condition Working capital increased to $67.4 million at June 30, 1998 from $62.3 million at September 30, 1997. During the first nine months of fiscal 1998: accounts receivable increased by $3.8 million as a result of the timing of sales and deliveries throughout the period; costs and estimated earnings on long-term contracts and inventories increased in the aggregate by $25.7 million in support of near-term production requirements (primarily 60K/TUNNER); and accounts payable and accrued expenses decreased by $1.0 million due to the timing of payments. Net cash used by operating activities was $4.4 million in the first nine months of fiscal 1998. Net cash generated by operating activities was $6.5 million in the same period of fiscal 1997. The 1998 cash usage was primarily due to the inventory requirements discussed in the previous paragraph. Capital expenditures were $9.8 million in the first nine months of fiscal 1998 compared with $7.5 million in the comparable period of fiscal 1997. Major expenditures in the current period included manufacturing equipment at Filtertek and PTI. On December 31, 1997, the Company completed the purchase of Euroshield OY for consideration which included $3.5 million in cash. Euroshield, based in Eura, Finland, designs and manufactures high quality shielding products used in the electromagnetic compatibility (EMC) industry. The Year 2000 Issue The Year 2000 (Y2K) issue refers to the inability of a date-sensitive computer program to recognize a two-digit date field designated as "00" as the year 2000. Mistaking "00" for 1900 could result in a system failure or miscalculations causing disruptions to operations, including manufacturing, a temporary inability to process transactions, send invoices, or engage in other normal business activities. This is a significant issue for most, if not all, companies with far reaching implications, some of which cannot be anticipated or predicted with any degree of certainty. The Company is currently assessing the magnitude of its Y2K issue and has already determined that it may be required to modify or replace certain portions of its software so that its computer systems will be able to function properly beyond December 31, 1999. This may require software replacement, reprogramming or other remedial action. The Company is also communicating with its suppliers and customers to determine the extent of the Company s vulnerability to the failure of third parties to remediate their own Y2K issue. In conjunction with this assessment, the Company is finalizing its action plans to address the Y2K issue, including contingencies to address unforeseen problems. The Company plans to use both internal and external resources to complete Y2K reprogramming, software replacement and testing. Preliminary plans anticipate completion of the Y2K remedial work by September 30, 1999. To date, the company has incurred approximately $1.25 million related to the Y2K remedial work. The total cost of the Y2K remedial work is estimated to be less than $5 million and will be expensed as incurred over the next 15 months. The expected costs of the project and the date on which the Company plans to complete the Y2K remediation work are based on management s best estimates, which were derived from numerous assumptions about future events, including the availability of certain resources, third-party modification plans, and other factors. However, there can be no guarantee that these estimates will be achieved and actual results could differ materially from those plans. Specific factors that might cause material differences include, but are not limited to, the availability and cost of personnel trained in this area and the ability to identify and correct all relevant computer codes. Forward Looking Statements Statements in this report that are not strictly historical are "forward looking" statements within the meaning of the safe harbor provisions of the federal securities laws. Investors are cautioned that such statements are only predictions, and speak only as of the date of this report. Actual results may differ due to risks and uncertainties which are described in the Company's Form 10-K for fiscal year 1997, on page 37 of the 1997 Annual Report to Shareholders and in The Year 2000 Issue section above.

                   A.  Capitalized terms used and not otherwise defined
     herein shall have the meanings assigned to them in the Credit
     Agreement, as amended hereby.
     
                   B.  ESCO and the Borrower have requested that certain
     provisions of the Credit Agreement be amended as set forth herein. 
     The Banks are willing to so amend the Credit Agreement subject to 
     the terms and conditions set forth herein.
     
                   Accordingly, in consideration of the mutual agreements 
     herein contained and other good and valuable consideration, the
     sufficiency and receipt of which are hereby acknowledged, the
     parties hereto hereby agree as follows:
     
     
                   SECTION 1.  Amendments.  (a) Section 1.01 of the Credit
     Agreement is hereby amended to add the following definitions:
     
                   "AMT" means Advanced Membrane Technology, Inc., a
             California corporation.
     
                   "AMT Investment" means the acquisition by a Wholly-
             Owned Consolidated Subsidiary of all of the outstanding
             common stock of AMT in exchange for consideration of
             approximately $15,000,000 (adjusted upward to reflect AMT's
             cash at closing and downward to reflect AMT's debt at
             closing) payable approximately 45% in cash and 55% in shares 
             of common stock of ESCO.
     
                   (b)  Article II of the Credit Agreement is hereby
     amended and restated by adding the following Section 2.17 at the
     end of such Article:
     
             SECTION 2.17.  Conversion.  Effective upon the
             consummation of the AMT Investment, (a) Working Capital
             Borrowings in an aggregate principal amount of $7,000,000
             shall be automatically converted into Term Borrowings and (b)
             the Working Capital Commitments shall be ratably reduced by
             $7,000,000.  Prior to the date of such conversion, the
             Borrower shall notify the Agent in writing of the Working
             Capital Borrowing or Borrowings (or portions thereof) that
             are to be converted pursuant to the preceding sentence.  The 
             conversion of each such Borrowing (or portion thereof) shall 
             be allocated ratably to the Loans included in such Borrowing. 
             If the aggregate principal amount of outstanding Working
             Capital Loans would be less than $7,000,000 on the date that
             such conversion is to be made pursuant to the first sentence
             of this Section, then the Borrower shall borrow additional
             Working Capital Loans so that there are not less than
             $7,000,000 in aggregate principal amount of Working Capital
             Loans outstanding at the time of such conversion. 
             Notwithstanding the foregoing, no such conversion shall
             become effective until receipt by the Security Agent of an
             amendment to each mortgage, deed of trust, assignment of
             leases or similar instrument or document required by law or

             substance reasonably satisfactory to the Required Banks) to
             be filed, registered or recorded in order to maintain in
             favor of the Security Agent (or a trustee on its behalf) for
             the benefit of the Banks a valid, legal and perfected first
             priority security interest in or lien on the real property
             (and improvements thereon) owned by the Borrower or any
             Specified Subsidiary and identified on Schedule 3.01(j) to
             the Credit Agreement, in each case duly executed and
             delivered by each mortgagor, grantor or pledgor thereunder.
     
             (c)  Section 5.09 of the Credit Agreement is hereby
     amended by deleting the words "clause (f), (l) or (n)" from the
     second sentence thereof and substituting the words "clause (f),
     (l), (n) or (o)".

     with a semicolon and by adding the following clauses (xv) and (xvi)
     at the end of such Section:

             DCS at any time outstanding under this clause (xvi) shall not
             exceed $2,500,000.
     
             (e)  Section 5.16 of the Credit Agreement is hereby

             pursuant to this clause (o) and any Debt of AMT remaining
             outstanding after the AMT Acquisition shall be treated as an 
             Investment made pursuant to clause (f) of this Section for
             purposes of determining compliance with the limitations of
             such clause (f).

     amended by replacing the period at the end of clause (n) thereof
     with "; and" and adding the following clause (o) at the end of such
     Section:
