                      DOCUMENTS INCORPORATED BY REFERENCE



The following documents have been incorporated by reference:

FORM 10-K DOCUMENT PART NUMBER - -------- ----------- (1) Annual Report to Shareholders for the year ended December 31, 1997 I, II, IV (2) Proxy Statement filed pursuant to Regulation 14A in connection with the registrant's Annual Meeting of Shareholders to be held on May 5, 1998 III
2 PART I Item 1. Business - ----------------- Products and Markets: -------------------- The primary business of the registrant and its affiliated companies is the manufacture and sale of products designed to protect the safety and health of workers throughout the world. Principal products include respiratory protective equipment that is air- purifying, air-supplied and self-contained in design. The registrant also produces instruments that monitor and analyze workplace environments and control industrial processes. Personal protective products include head, eye and face, body and hearing protectors. Many of these products are sold under the registered trademark "MSA", and have wide application for workers in industries that include manufacturing, fire service, power generation, telecommunications, mining, chemicals, petroleum, construction, pulp and paper processing, transportation, government, automotive, aerospace, asbestos abatement, and hazardous materials clean-up. Other products manufactured and sold, which do not fall within the category of safety and health equipment, include boron-based and other specialty chemicals. The registrant and its affiliated companies are in competition with many large and small enterprises. In the opinion of management, the registrant is a leader in the manufacture of safety and health equipment. Orders, except under contracts with U.S. government agencies and with international governments, are generally filled promptly after receipt and the production period for special items is usually less than one year. The backlog of orders under contracts with U.S. government agencies and certain international governments is summarized as follows: December 31 --------------------------------- 1997 1996 1995 ---- ---- ---- (In thousands) --------------------------------- U.S. Government Agencies $19,600 $14,400 $30,400 International Governments 0 900 7,900 Approximately $300,000 under contracts with U.S. government agencies is expected to be shipped after December 31, 1998. 3 Sales of products to U.S. government agencies continued to decrease in 1997; however, incoming orders were slightly higher than shipments in 1997, and about the same as 1996 incoming orders. The company's business is not dependent upon a single customer or group of related customers, the loss of which would have a material adverse effect on the registrant's results. Further information with respect to the registrant's products, operations in different geographic areas, equity in earnings and assets of international affiliated companies is reported at Note 5 of Notes to Consolidated Financial Statements contained in the registrant's Annual Report to Shareholders for the year ended December 31, 1997, incorporated herein by reference. Research: -------- The registrant and its affiliated companies engage in applied research with a view to developing new products and new applications for existing products. Most of its products are designed and manufactured to meet currently applicable performance and test standards published by groups such as ANSI (American National Standards Institute), MSHA (Mine Safety & Health Administration), NIOSH (National Institute for Occupational Safety and Health), UL (Underwriters' Laboratories), SEI (Safety Equipment Institute) and FM (Factory Mutual). The registrant also from time to time engages in research projects for others such as the Bureau of Mines and the Department of Defense or its prime contractors. Registrant-sponsored research and development costs were $16,668,000 in 1997, $19,122,000 in 1996, and $20,366,000 in 1995. In the aggregate, patents have represented an important element in building up the business of the registrant and its affiliates, but in the opinion of management no one patent or group of patents is of material significance to the business as presently conducted. General: ------- The company was founded in 1914 and is headquartered in Pittsburgh, Pennsylvania. As of December 31, 1997, the registrant and its affiliated companies had approximately 4,200 employees, of which 2,100 were employed by international affiliates. None of the U.S. employees is subject to the provisions of a collective bargaining agreement. In the United States and in those countries in which the registrant has affiliates, its products are sold by its own salespersons, independent distributors 4 and/or manufacturers' representatives. In international countries where the registrant has no affiliate, products are sold primarily through independent distributors located in those countries. The registrant is cognizant of environmental responsibilities and has taken affirmative action regarding this responsibility. There are no current or expected legal proceedings or expenditures with respect to environmental matters which would materially affect the operations of the registrant and its affiliates. Generally speaking, the operations of the registrant and its affiliates are such that it is possible to maintain sufficient inventories of raw materials and component parts on the manufacturing premises. Equipment and machinery for processing chemicals and rubber, plastic injection molding equipment, molds, metal cutting, stamping and working equipment, assembly fixtures and similar items are regularly acquired, repaired or replaced in the ordinary course of business at prevailing market prices as necessary. In January 1998, the company announced that it had initiated action to sell its domestic affiliate, HAZCO Services, Inc. (due to its incompatibility with MSA's newly-established network of distributors). Further information about the registrant's business is included in Management's Discussion and Analysis at pages 10 to 12 of the Annual Report to Shareholders, incorporated herein by reference. 5 Executive Officers: ------------------

Management's Discussion and Analysis
 
Results of Operations

     1997 versus 1996 -- Sales for 1997 were $494.3 million, a decrease of $6.7
million, or 1%, from $501.0 million in 1996. The slight decline in sales
reflects the absence of U.S. military gas mask business and the negative
currency translation effect of the strong U.S. dollar, particularly in relation
to continental European currencies. These decreases were offset by improved
sales in U.S. commercial markets and modest growth in local currency sales in
international markets.

     Sales by U.S. operations decreased 3% in 1997. Sales for 1996 included some
military gas mask business on contracts which were expiring and several large
special instrument orders. Sales of specialty chemicals continued to grow in
1997, although at a more modest pace than in recent years. Personal protective
equipment sales in commercial markets improved during 1997 and also benefited
from the inclusion of a full year's sales from the fall protection and
disposable respirator acquisitions which were made in 1996.

     Sales by European operations, stated in U.S. dollars, decreased 11% in
1997. Although local currency sales in Europe improved slightly in 1997,
negative currency translation effects, particularly in Germany, resulted in the
decrease when stated in U.S. dollars. Sales by MSA's operations outside the U.S.
and Europe increased 22% in 1997. The inclusion of MSA Africa, which became
wholly owned at the beginning of 1997, was a major factor in this improvement.
Latin American and Asian operations reported strong sales growth.

     Gross profit for 1997 was $192.1 million, a decrease of $1.8 million, or
1%, from $193.9 million in 1996. The 1997 ratio of gross profit to sales
improved slightly to 38.9% from 38.7%. While the gross profit percentage has
been relatively stable over the past three years, the current levels represent
an overall improvement from the roughly 36% gross profit level in 1992 through
1994. The improved gross profit percentage in 1997 is the result of cost
reductions from improved manufacturing processes and the continuing sales mix
shift away from lower-margin military sales to higher-margin commercial sales.
Gross profit in 1996 also benefited from liquidations of lower-cost LIFO
inventories which were not repeated in 1997. Excluding this effect, gross margin
percentages improved in 1997 in the U.S., while those in Europe slipped.

     Research and development expenses in 1997 were $16.7 million, compared to
$19.1 million in 1996. The decrease reflects an emphasis on core-product
research, more limited external research purchases, and higher reimbursements
for research performed under contracts with customers in 1997. Research expenses
incurred in Germany were also lower, when stated in U.S. dollars, due to
currency translation effects.

     Depreciation, selling and administrative expenses increased $516,000 to
$156.0 million in 1997, and increased as a percent of sales to 31.6% from 31.0%
in 1996. The modest increase reflects expenses incurred in conjunction with the
Enterprise Wide System and Global New Product Development initiatives, partially
offset by favorable currency translation effects associated with the strong U.S.
dollar. Ongoing depreciation, and selling and administrative expenses were
generally lower than in 1996.

     Currency exchange losses charged to income in 1997 were $40,000, compared
to $735,000 in 1996. The most significant losses from currency valuation changes
in both years occurred in Brazil.

     The effective income tax rate, for which further information is included in
note 8, was 39.7% in 1997 and 37.1% in 1996. The higher effective rate in 1997
reflects additional tax expenses at international companies.

     Net income in 1997 decreased $1.2 million to $21.9 million from $23.1
million in 1996. Basic earnings per share of common stock improved in 1997 to
$4.81, compared to $4.74 in 1996. Earnings per share benefited from share
repurchases that reduced average shares outstanding by 7% in 1997.

     1996 versus 1995 -- Sales for 1996 were $501.0 million, an increase of
$13.3 million, or 3%, from $487.7 million in 1995. The increase occurred
primarily in U.S. commercial markets. Sales by international operations improved
modestly in 1996, mainly in Europe.

     Sales by U.S. operations increased 4% in 1996. The 1996 U.S. sales increase
occurred primarily in commercial markets, while sales to U.S. government
agencies decreased significantly, continuing the trend of declining military gas
mask business. Commercial sales of instrument and specialty chemicals sustained
the growth pattern shown in 1995 and 1994. Conversely, lower government funding
and changing customer preferences continued to reduce commercial sales of
respiratory protection equipment.

     Sales by European operations, stated in U.S. dollars, increased 3% in 1996.
The modest growth reflected a stagnant European economic environment in 1996,
after noticeable growth in 1995. Other international markets were about the same
in 1996, after significant growth in 1995 occurred in Australia, Brazil, and
Chile.

     Gross profit for 1996 was $193.9 million, a $3.1 million, or 2% increase
over $190.8 million in 1995. The 1996 ratio of gross profit to sales declined
slightly to 38.7% from 39.1% in 1995. Gross margin percentages in both 1996 and
1995 improved as a result of manufacturing process improvements, the shift in
product mix away from military sales to commercial sales, and significant
credits resulting from liquidations of lower-cost LIFO inventories.

     Depreciation, selling and administrative expenses in 1996 decreased $2.8
million, or 2%, to $155.4 million, and decreased as a percent of sales to 31.0%
from 32.4% in 1995. The decrease reflects lower field sales and marketing
expenses, resulting from the rationalization of distribution channels in the
U.S.

     Currency exchange losses charged to income in 1996 were $735,000, compared
to $1.2 million in 1995. The most significant losses from currency valuation
changes in both years occurred in Brazil and Mexico.

     Results for 1996 also included a $2.5 million settlement with the U.S.
government regarding the partial termination of earlier gas mask contracts,
which resulted in the recovery of costs incurred in prior years.

     The effective income tax rate, for which further information is included in
note 8, was 37.1% in 1996 and 42.9% in 1995. The lower effective rate in 1996
reflects additional tax benefits from international operations.

     Net income in 1996 increased $4.2 million to $23.1 million from $18.9
million in 1995. Basic earnings per share of common stock improved in 1996 to
$4.74, compared to $3.32 in 1995. Earnings per share benefited from share
repurchases that reduced average shares outstanding 14% in 1996.

Restructuring

     During 1997 the company substantially completed the U.S. restructuring
activities which were initiated in late 1996 to reduce costs and better align
production capacities with demand. The most significant of these activities was
the closing of the Esmond, Rhode Island, plant, which was required primarily
because of low levels of U.S. military gas mask business. In 1997, Esmond's
commercial product activities were relocated to other manufacturing facilities,
all Esmond employees were relocated, released, or retired and the facility was
vacated. Provisions for separation pay and asset impairments that were
established in 1996 were adequate to complete these activities without
significant adjustment. The net effect of U.S. restructuring activities on 1997
results was minimal, considering both expenses incurred and related asset sale
and pension curtailment gains.

     The most significant costs included in the $2.2 million restructuring
charge in 1997 relate to workforce reductions at European operations, including
$1.7 million in accrued severance and phased retirement pay in Germany.

     Restructuring charges of $7.8 million in 1996 related primarily to
separation pay and asset impairment write-downs connected with the Esmond plant
closing. Charges of $730,000 in 1995 were for workforce reductions at
international locations.

Liquidity and Financial Condition

     Cash and cash equivalents decreased $5.2 million during 1997, compared to a
$6.9 million decrease in 1996. The company's principal source of financing
capital expenditures and internal growth is cash flow from operations.
Operations provided cash of $30.9 million in 1997, compared to $56.5 million in
1996. The decrease primarily reflects increased working capital needs in 1997
associated with the U.S. restructuring activities and the currency translation
effects of the strong U.S. dollar on the net current assets of international
affiliates. Cash provided by operations in 1996 benefited from significant
inventory reductions.

     The company has an ongoing program of plant and equipment modernization to
improve the efficiency of existing manufacturing facilities. Capital
expenditures were $35.3 million in 1997, compared to $21.6 million in 1996.
Increased capital expenditures in 1997 include costs for new enterprise wide
information systems, manufacturing facility improvements associated with the
U.S. restructuring activities, and a new headquarters building at HAZCO
Services, Inc. In the past five years, approximately $120 million has been spent
on new plants, equipment and distribution facilities, and information systems.


                                      11

 
     Dividends paid on the common stock during 1997 (the 80th consecutive year
of dividend payment) were $1.24 per share, up from the $1.10 per share in 1996
and $1.06 per share in 1995. Cash dividends are paid at a conservative
percentage of income, which is consistent with the company's practice of
financing growth internally. During 1997, the company repurchased 184,708 common
shares for $11.3 million. As of December 31, 1997, an additional 325,666 shares
may be repurchased under current authorizations.

     The average amount of short-term debt outstanding during 1997 and 1996 was
$21.6 million and $2.9 million, respectively. Borrowings during 1997 were
increased primarily to finance capital expenditures. Credit available at year-
end with banks was the U.S. dollar equivalent of $48.6 million, of which $25.8
million was unused. Short-term debt of international affiliates is payable in
local currencies, which is in keeping with the company's policy of reducing
currency exchange exposures by offsetting local currency assets with local
currency debt.

     Long-term debt and the current portion thereof decreased $2.2 million to
$13.7 million, a conservative 5.4% of total capital. Total capital is defined as
long-term debt plus the current portion of long-term debt and shareholders'
equity.

     Accounts receivable decreased $10.4 million to $91.4 million at December
31, 1997. Trade receivables expressed in number of days' sales outstanding were
65 days, compared to 71 days in 1996. Inventories increased $4.0 million to
$81.1 million at December 31, 1997. Inventory measured against sales turned 6.1
times in 1997 and 6.5 times in 1996. The working capital ratio was 2.1 and 2.5
to 1 at year's end 1997 and 1996, respectively.

     The company's financial position remains strong and should provide adequate
capital resources for growth.

Cumulative Currency Translation Adjustment

     The year-end position of the U.S. dollar relative to international
currencies resulted in translation losses of $7.2 million being charged to the
cumulative translation adjustments shareholders' equity account in 1997,
compared to a $747,000 loss in 1996 and a $2.9 million gain in 1995. Significant
1997 translation losses occurred in Europe, particularly Germany, and in
Australia. Losses in 1996 in Germany and Japan were partially offset by gains in
Australia and Britain.

Recent Developments and Outlook

     The company is currently replacing its existing information systems with an
Enterprise Wide System (EWS) of business software to integrate and better serve
global operating and information requirements. This software, which is already
in use at MSA Britain, is compatible with year 2000 processing requirements. The
planned implementation schedule for EWS at MSA companies throughout the world is
expected to avoid potential year 2000 problems with existing computer systems.

     As part of the ongoing initiatives to rationalize distribution channels and
improve operating performance, the company has initiated action to sell HAZCO
Services, Inc. (due to its incompatability with MSA's newly-established network
of distributors). This action, which is expected to be completed during 1998, is
not estimated to have a material impact on 1998 results. The 1997 operating
results of HAZCO Services, Inc. are not material to the consolidated financial
statements.

Common Stock

     At December 31, 1997, there were 4,455,915 shares of common stock
outstanding. There were approximately 400 identifiable common stockholders on
November 14, 1997, a recent date for dividends. The common stock last-sale price

See notes to consolidated financial statements. 16 Notes to Consolidated Financial Statements Note 1--Basis of Presentation SIGNIFICANT ACCOUNTING POLICIES ARE STATED IN ITALICS AT THE APPLICABLE NOTES TO CONSOLIDATED FINANCIAL STATEMENTS. THE PREPARATION OF FINANCIAL STATEMENTS IN CONFORMITY WITH GENERALLY ACCEPTED ACCOUNTING PRINCIPLES REQUIRES MANAGEMENT TO MAKE ESTIMATES AND ASSUMPTIONS THAT AFFECT THE REPORTED AMOUNTS OF ASSETS AND LIABILITIES AND DISCLOSURE OF CONTINGENT ASSETS AND LIABILITIES AT THE DATE OF THE FINANCIAL STATEMENTS AND THE REPORTED AMOUNTS OF REVENUES AND EXPENSES DURING THE REPORTING PERIOD. ACTUAL RESULTS COULD DIFFER FROM THOSE ESTIMATES. ALL SIGNIFICANT MAJORITY-OWNED COMPANIES ARE INCLUDED IN THE CONSOLIDATED FINANCIAL STATEMENTS. INVESTMENTS IN WHICH THE COMPANY HAS AN EQUITY INTEREST OF 20% TO 50% ARE CARRIED AT EQUITY IN NET ASSETS. INTERCOMPANY TRANSACTIONS ARE ELIMINATED IN CONSOLIDATION. SALES UNDER CONTRACTS ARE RECORDED AT FIXED OR ESTIMATED CONTRACT SALES PRICES AS DELIVERIES ARE MADE. CONTRACTS REQUIRING PERFORMANCE OVER SEVERAL PERIODS ARE ACCOUNTED FOR BY THE PERCENTAGE-OF-COMPLETION METHOD OF ACCOUNTING. PROFITS EXPECTED TO BE REALIZED ARE BASED ON ESTIMATES OF TOTAL SALES AND COSTS AT COMPLETION. THESE ESTIMATES ARE PERIODICALLY REVIEWED AND REVISED DURING THE CONTRACT PERFORMANCE PERIOD. ADJUSTMENTS TO PROFITS ARE RECORDED IN THE PERIOD IN WHICH ESTIMATES ARE REVISED; LOSSES ARE RECOGNIZED IN FULL AS THEY ARE IDENTIFIED. PROPERTY IS STATED AT COST. DEPRECIATION IS BASED ON ESTIMATED USEFUL LIVES USING ACCELERATED AND STRAIGHT-LINE METHODS. MAINTENANCE AND REPAIRS ARE CHARGED TO EXPENSE. RENEWALS AND BETTERMENTS WHICH SUBSTANTIALLY EXTEND THE USEFUL LIFE OF PROPERTY ARE CAPITALIZED. PROFITS OR LOSSES RESULTING FROM DISPOSITIONS ARE INCLUDED IN INCOME. THE FINANCIAL STATEMENTS OF COMPANIES FOR WHICH THE UNITED STATES DOLLAR IS DETERMINED TO BE THE FUNCTIONAL CURRENCY ARE TRANSLATED USING CURRENT AND HISTORIC EXCHANGE RATES; ADJUSTMENTS RELATED THERETO ARE INCLUDED IN INCOME FOR THE CURRENT PERIOD. THE FINANCIAL STATEMENTS OF ALL OTHER COMPANIES ARE TRANSLATED FROM THEIR FUNCTIONAL CURRENCY INTO UNITED STATES DOLLARS USING CURRENT EXCHANGE RATES; THE RESULTANT TRANSLATION ADJUSTMENTS ARE NOT INCLUDED IN INCOME BUT ARE ACCUMULATED IN A SEPARATE EQUITY ACCOUNT. TRANSACTION GAINS AND LOSSES ARE RECOGNIZED IN INCOME FOR THE CURRENT PERIOD. CASH AND CASH EQUIVALENTS IN THE CONSOLIDATED STATEMENT OF CASH FLOWS INCLUDES TEMPORARY INVESTMENTS THAT ARE READILY MARKETABLE AND HAVE MINIMAL RISK AS TO CHANGE IN VALUE. CERTAIN SECURITIES HAVE MATURITIES IN EXCESS OF NINETY DAYS; BUT, AS PART OF THE COMPANY'S CASH MANAGEMENT PROGRAM, MATURITIES ARE SCHEDULED BASED ON EXPECTED CASH NEEDS FOR THE ENSUING TWELVE MONTHS.

OTHER INVENTORIES ARE VALUED AT THE LOWER OF COST, USING AVERAGE OR CURRENT STANDARD COSTS WHICH APPROXIMATE ACTUAL COSTS ON A FIRST-IN, FIRST-OUT (FIFO) BASIS, OR MARKET, DETERMINED BY REPLACEMENT COST OR NET REALIZABLE VALUE. Reductions in inventory quantities during 1997, 1996, and 1995 resulted in liquidations of LIFO inventory quantities carried at lower costs prevailing in prior years. The effect of these liquidations reduced cost of sales by $572,000 in 1997, $10,361,000 in 1996 and $5,455,000 in 1995, and increased net income by $349,000 ($.08 per share), $6,217,000 ($1.28 per share) and $3,200,000 ($.56 per share), respectively.

Transfers between geographic areas are stated at established intercompany selling prices. Operating profit is total revenues less operating expenses. Interest income and expense, equity in unconsolidated affiliates, facilities consolidation and restructuring charges, contract costs recovery, and income taxes have not been included in computing operating profit. Corporate assets not included in identifiable assets are principally cash and investments. Note 6--Restructuring Restructuring charges of $2,164,000 in 1997, most of which relate to planned workforce reductions, include $1,743,000 for severance and phased retirement pay in Germany. Relocation and start-up costs of $1,190,000 related to the closing of the Esmond, Rhode Island, safety products manufacturing facility were largely offset by pension curtailment gains of $1,185,000. Charges of $7,786,000 in 1996 were principally for separation pay and asset impairments associated with the Esmond plant closing. Charges of $730,000 in 1995 related to workforce reductions at international locations. Note 7--Research and Development Expense RESEARCH AND DEVELOPMENT COSTS, CHARGED AGAINST INCOME AS INCURRED, were $16,668,000 in 1997, $19,122,000 in 1996, and $20,366,000 in 1995. 18 Note 8--Income Taxes INCOME TAXES ARE ACCOUNTED FOR IN ACCORDANCE WITH STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 109. DEFERRED TAX BALANCES ARE STATED AT TAX RATES EXPECTED TO BE IN EFFECT WHEN TAXES ARE ACTUALLY PAID OR RECOVERED.

Second cumulative preferred voting stock--none has been issued. As to the 4 1/2% cumulative preferred stock, 71,373 shares have been issued (none during the three years ended December 31, 1997), while the amounts held in treasury at each year end are 1997 - 49,313 shares, $1,595,000; 1996 - 49,313 shares, $1,595,000; and 1995 - 47,935 shares, $1,553,000. The company has established the Mine Safety Appliances Company Stock Compensation Trust, the purpose of which is to fund certain benefit plans, including employee stock options and awards. In 1996, the company sold 600,000 treasury shares, at market value, to the Trust, in exchange for a $28,200,000 promissory note, 8% interest, payable to the company. The company has adopted a Shareholder Rights Plan which includes distribution of rights as a dividend at the rate of one right for each share of the company's common stock owned on February 21, 1997. Each right entitles the holder to buy a fraction of a share of participating preferred stock for $225 in the event certain persons or groups acquire 15% or more of the company's outstanding common stock. Each right entitles its holder to purchase common stock having a value twice the exercise price. The rights will expire on February 21, 2007. Note 10--Leases The company leases office space, manufacturing and warehouse facilities, automobiles and other equipment under operating leases expiring at various dates through 2001. Rent expense was $6,751,000 in 1997, $6,956,000 in 1996, and $6,970,000 in 1995. Future minimum rental payments under noncancelable leases are not significant. Note 11--Earnings per Share BASIC EARNINGS PER SHARE IS COMPUTED ON THE WEIGHTED AVERAGE NUMBER OF COMMON SHARES OUTSTANDING DURING THE PERIOD. DILUTED EARNINGS PER SHARE INCLUDES THE EFFECT OF THE WEIGHTED AVERAGE STOCK OPTIONS OUTSTANDING DURING THE PERIOD, USING THE TREASURY STOCK METHOD. ANTIDILUTIVE OPTIONS ARE NOT CONSIDERED IN COMPUTING DILUTED EARNINGS PER SHARE.

20 Note 12--Short-Term Debt Short-term bank lines of credit amounted to $48,610,000 of which $25,814,000 was unused at December 31, 1997. Generally, these short-term lines of credit are renewable annually, and there are no significant commitment fees or compensating balance requirements. Short-term borrowings with banks, which exclude the current portion of long-term debt, were $23,762,000 and $5,491,000 at December 31, 1997 and 1996, respectively. The average month-end balance of total short- term borrowings during 1997 was $21,649,000 while the maximum month-end balance of $32,749,000 occurred at November 30, 1997. The average interest rate during 1997 was approximately 8% based upon total short-term interest expense divided by the average month-end balance outstanding, and 8% at year-end. Note 13--Retirement Plans Substantially all employees are covered by non-contributory pension plans. Various U.S. employees also participate in a contributory retirement savings plan wherein employees may contribute from 1% to 10% of their compensation to a trust fund, to which the company contributes an amount equal to 50% of the employees' contributions not in excess of 8%. The company's (income)/expense for all plans was ($7,737,000) in 1997, $2,798,000 in 1996, and $3,069,000 in 1995. THE NON-CONTRIBUTORY PENSION PLANS ARE ACCOUNTED FOR IN ACCORDANCE WITH STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 87 WHICH REQUIRES USE OF THE PROJECTED UNIT CREDIT COST METHOD TO DETERMINE THE PROJECTED BENEFIT OBLIGATION AND PLAN COST. THE PRINCIPAL U.S. PLAN IS FUNDED IN COMPLIANCE WITH THE EMPLOYEE RETIREMENT INCOME SECURITY ACT (ERISA). IT IS THE GENERAL POLICY TO FUND CURRENT COSTS FOR THE INTERNATIONAL PLANS EXCEPT IN GERMANY, WHERE IT IS COMMON PRACTICE AND PERMISSIBLE UNDER TAX LAWS TO ACCRUE BOOK RESERVES. A minimum liability is recognized for unfunded defined benefit plans for which the accumulated benefit obligation exceeds accrued pension costs. The amount of the minimum liability in excess of unrecognized prior service cost, net of tax benefit, is recorded as a reduction in shareholders' equity. Non-contributory plan benefits are generally based on years of service and employees' compensation during the last years of employment. Benefits are paid from funds previously provided to trustees or are paid by the company and charged to the book reserves. Information pertaining to the non-contributory defined benefit plans is provided in the following tables.

21 Note 14--Postretirement Benefits The company provides certain health care benefits and limited life insurance for retired employees and their eligible dependents, THE COSTS FOR WHICH ARE ACCOUNTED FOR IN ACCORDANCE WITH STATEMENT OF FINANCIAL ACCOUNTING STANDARDS (SFAS) NO. 106. SFAS NO. 106 REQUIRES RECOGNITION OF RETIREE HEALTH AND LIFE INSURANCE BENEFITS DURING THE EMPLOYEES' SERVICE WITH THE COMPANY. Further information about these benefits is provided in the following tables.

Annual rates of increase in the costs of covered health care benefits assumed for 1997 were 6%, decreasing gradually to 4% for the year 1999 and thereafter. The health care cost trend rate assumption has a significant effect on the amounts reported; a one-percentage-point increase in each year would increase the accumulated postretirement benefit obligation by $967,000 and increase the current service and interest costs for the year by $112,000. Note 15--Stock Plans The company's Management Share Incentive Plan permitted the granting of restricted stock awards and stock options to eligible key employees through December 1997. The 1990 Non-Employee Directors' Stock Option Plan provides for annual grants of stock options to eligible directors. As of December 31, 1997, there were 35,800 shares reserved for future grants pursuant to this Plan. Stock options are generally granted at market value option prices and expire after ten years (limited instances of option prices in excess of market value and expiration after five years). Restricted stock awards are granted (17,050 shares in 1996) to employees without payment to the company in consideration of services to be performed in ensuing five-year periods. THE COMPANY APPLIES ACCOUNTING PRINCIPLES BOARD OPINION 25 AND RELATED INTERPRETATIONS IN ACCOUNTING FOR THE PLANS. ACCORDINGLY, NO COMPENSATION COST HAS BEEN RECOGNIZED FOR THE STOCK OPTION GRANTS. COMPENSATION COST FOR THE RESTRICTED STOCK AWARDS IS MEASURED BY THE MARKET VALUE OF THE SHARES WHEN AWARDED AND IS AMORTIZED BY CHARGES TO OPERATIONS OVER THE PERIOD THAT THE EMPLOYEE PROVIDES THE SERVICE. The expense charged to operations was $436,000 in 1997, $350,000 in 1996, and $238,000 in 1995. The company's net income and earnings per share would not be significantly affected if compensation cost for these Plans was determined based on fair value at grant dates consistent with the method provided in Statement of Financial Accounting Standards No. 123. A summary of the two stock option plans follows:
