Annual Report (Form 10-K), fiscal year 1993

Item 1. Business.
Sigma-Aldrich Corporation engages through subsidiaries in two lines of business: the production and sale of a broad range of biochemicals, organic and inorganic chemicals, radiolabeled chemicals, diagnostic reagents, chromatography products and related products (hereinafter referred to as "chemical products"), and the manufacture and sale of metal components for strut, cable tray, pipe support and telecommunication systems and electrical enclosures (hereinafter referred to as "metal products" or "B-Line"). Its principal executive offices are located at 3050 Spruce Street, St. Louis, Missouri 63103.
Sigma-Aldrich Corporation (hereinafter referred to as the "Company", which term includes all consolidated subsidiaries of the Company) was incorporated under the laws of the State of Delaware in May 1975. Effective July 31, 1975 ("Reorganization"), the Company succeeded, as a reporting company, Sigma International, Ltd., the predecessor of Sigma Chemical Company ("Sigma"), and Aldrich Chemical Company, Inc. ("Aldrich"), both of which had operated continuously for more than 20 years prior to the Reorganization. Effective December 9, 1980, B-Line Systems, Inc., previously a subsidiary of Sigma, became a subsidiary of the Company.
Effective June 23, 1989, the Company purchased all of the issued and outstanding capital stock of Fluka Chemie AG ("Fluka"), a Swiss corporation, from Ciba-Geigy International AG, F. Hoffman- LaRoche & Co. Limited and eleven minority shareholders.
Effective May 5, 1993, the Company acquired the net assets and business of Supelco, Inc.("Supelco"), a worldwide supplier of chromatography products used in chemical research and production, from Rohm and Haas Company.
(a) Chemical Products.
1) Products:
The Company distributes approximately 71,000 chemical products for use primarily in research and development, in the diagnosis of disease, and as specialty chemicals for manufacturing. In laboratory applications, the Company's products are used in the fields of biochemistry, synthetic chemistry, quality control and testing, immunology, hematology, pharmacology, microbiology, neurology, and endocrinology, and in the studies of life processes. Sigma diagnostic products are used in the detection of heart, liver and kidney diseases and various metabolic disorders. Certain of these diagnostic products are used in measuring concentrations of various naturally occurring substances in the blood, indicative of certain pathological conditions. The diagnostic products are used in manual, semi-automated and automated testing procedures. Supelco offers a full line of chromatography products and application technologies for analyzing and separating complex chemical mixtures. The line includes items for the collection and preparation of various samples for further chemical analysis, gas and liquid chromatography, reference standards and related laboratory products.
Aldrich also offers approximately 38,000 esoteric chemicals as a special service to customers interested in screening them for application in many areas (such as medicine and agriculture). This area accounts for less than 1% of the Company's sales.
Because of continuing developments in the field of research, there can be no assurance of a continuing market for each of the Company's products. However, through a continuing review of technical literature, along with constant communications with customers, the Company keeps abreast of the trends in research and diagnostic techniques. This information, along with its own research technology, determines the Company's development of improved and/or additional products.
2) Production and Purchasing:
The Company has chemical production facilities in Milwaukee and Sheboygan, Wisconsin (Aldrich); St. Louis, Missouri (Sigma); Bellefonte, Pennsylvania (Supelco); Germany (Aldrich Chemie GmbH and Co. K.G.); Israel (Makor Chemicals Limited); Switzerland (Fluka) and the United Kingdom (Sigma Chemical Company Ltd.). A minor amount of production is done by some of the Company's other subsidiaries. Biochemicals and diagnostic reagents are primarily produced by extraction and purification from yeasts, bacteria and other naturally occurring animal and plant sources. Organic and inorganic chemicals and radiolabeled chemicals are primarily produced by synthesis. Chromatography media and columns are produced using proprietary chemical synthesis and proprietary preparation processes. Similar processes are used for filtration and sample collection processes.
Of the approximately 71,000 products listed in the Sigma, Aldrich, Fluka and Supelco catalogs, the Company produced approximately 31,000 which accounted for 44% of the net sales of chemical products for the year ended December 31, 1993. The remainder of products were purchased from a large number of sources either under contract or in the open market.
No one supplier accounts for as much as 10% of the Company's chemical purchases. The Company has generally been able to obtain adequate supplies of products and materials to meet its needs.
Whether a product is produced by the Company or purchased from outside suppliers, it is subjected to quality control procedures, including the verification of purity, prior to final packaging. This is done by a combined staff of 201 chemists and lab technicians utilizing sophisticated scientific equipment.
3) Distribution and Sales:
The Company markets its chemical products primarily through Sigma, Aldrich, Fluka and Supelco under their own trademarks and labels. Marketing of products is primarily done through the distribution of over 2,600,000 comprehensive catalogs to customers and potential customers throughout the world. This is supplemented by certain specialty catalogs, by advertising in chemical and other scientific journals, by direct mail distribution of in-house publications and special product brochures and by personal visits by technical and sales representatives with customers.
For customer convenience, Sigma packages approximately 300 combinations of certain of its individual products in diagnostic kit form. A diagnostic kit will include products which, when used in a series of manual and/or automated testing procedures, will aid in detecting particular conditions or diseases. The sale of these kits is promoted by a field sales unit. Diagnostic kits accounted for less than 10% of the Company's net sales of chemical products in the year ended December 31, 1993.
During the year ended December 31, 1993, products were sold to approximately 129,000 customers, including hospitals, universities, clinical laboratories as well as private and governmental research laboratories. The majority of the Company's sales are small orders in laboratory quantities averaging less than $200. The Company also makes its chemical products available in larger-than-normal laboratory quantities for use in manufacturing. Sales of these products accounted for approximately 15% of chemical sales in 1993. During the year ended December 31, 1993, no one customer and no one product accounted for more than 1% of the net sales of chemical products.
Sigma, Aldrich, Fluka and Supelco encourage their customers and potential customers, wherever located, to contact them by telephone "collect" or on "toll-free" WATS lines for technical staff consultation or for placing orders. Order processing, shipping, invoicing and product inventory are computerized. Shipments are made seven days a week from St. Louis, six days a week from Milwaukee, England, Germany, Israel and Japan and five days a week from all other locations. The Company strives to ship its products to customers on the same day an order is received and carries significant inventories to maintain this policy.
4) International Operations:
In the year ended December 31, 1993, approximately 50% of the Company's net sales of chemical products were to customers located in foreign countries. These sales were made directly by Sigma, Aldrich, Fluka and Supelco, through distributors and by subsidiaries organized in Australia, Belgium, Brazil, Canada, Czech Republic, England, France, Germany, Holland, Hungary, India, Israel, Italy, Japan, Mexico, Scotland, Singapore, South Korea, Spain and Switzerland. Several foreign subsidiaries also have production facilities.
For sales with final destinations in a foreign market, the Company has a Foreign Sales Corporation ("FSC") subsidiary which provides the Company certain Federal income tax advantages. The effect of the tax rules governing the FSC is to lower the effective Federal income tax rate on export income. The Company intends to continue to comply with the provisions of the Internal Revenue Code relating to FSCs.
The Company's foreign operations and domestic export sales are subject to currency revaluations, changes in tariff restrictions and restrictive regulations of foreign governments, among other factors inherent in these operations. The Company is unable to predict the extent to which its business may be affected in the future by these matters. During the year ended December 31, 1993, approximately 10% of the Company's domestic operations' chemical purchases were from foreign suppliers. Additional information regarding international operations is included in Note 9 to the consolidated financial statements on pages 21 and 22 of the 1993 Annual Report which is incorporated herein by reference.
5) Patents and Trademarks:
The Company's patents are not material to its operations. The Company's significant trademarks are the brand names "Sigma", "Aldrich", "Fluka", "Supelco" and "B-Line" and their related logos which have various expiration dates and are expected to be renewed indefinitely.
6) Regulations:
The Company engages principally in the business of selling products which are not foods or food additives, drugs, or cosmetics within the meaning of the Federal Food, Drug and Cosmetic Act, as amended (the "Act"). A limited number of the Company's products, including in-vitro diagnostic reagents, are subject to labeling, manufacturing and other provisions of the Act. The Company believes it is in compliance in all material respects with the applicable regulations.
The Company believes that it is in compliance in all material respects with Federal, state and local environmental and safety regulations relating to the manufacture, sale and distribution of its products. The following are brief summaries of some of the Federal laws and regulations which may have an impact on the Company's business. These summaries are only illustrative of the extensive regulatory requirements of the Federal, state and local governments and are not intended to provide the specific details of each law or regulation.
The Clean Air Act (CAA), as amended, and the regulations promulgated thereunder, regulates the emission of harmful pollutants to the air outside of the work environment. Federal or state regulatory agencies may require companies to acquire permits, perform monitoring and install control equipment for certain pollutants.
The Clean Water Act (CWA), as amended, and the regulations promulgated thereunder, regulates the discharge of harmful pollutants into the waters of the United States. Federal or state regulatory agencies may require companies to acquire permits, perform monitoring and to treat waste water before discharge to the waters of the United States or a Publicly Owned Treatment Works (POTW).
The Occupational Safety and Health Act of 1970 (OSHA), including the Hazard Communication Standard ("Right to Know"), and the regulations promulgated thereunder, requires the labeling of hazardous substance containers, the supplying of Material Safety Data Sheets ("MSDS") on hazardous products to customers and hazardous substances the employee may be exposed to in the workplace, the training of the employees in the handling of hazardous substances and the use of the MSDS, along with other health and safety programs.

Approximately 700 products, for which sales are immaterial to the total sales of the Company, are subject to control by either the Drug Enforcement Administration ("DEA") or the Nuclear Regulatory Commission ("NRC"). The DEA and NRC have issued licenses to several Company sites to permit importation, manufacture, research, analysis, distribution and export of certain products. The Company screens customer orders involving products regulated by the NRC and the DEA to verify that a license, if necessary, has been obtained.
(b) Metal Products.
Components for strut, cable tray and pipe support systems are manufactured by B-Line at its facilities in Highland and Troy, Illinois; Norcross, Georgia and Reno, Nevada. Components and complete systems used to support telecommunications apparatus and cabling are manufactured and sold by B-Line through its Saunders Communications unit, which is located in Santa Fe Springs, California. Circle AW Products Company, which was acquired on June 16, 1993 and operates as a wholly-owned subsidiary of B-Line, manufactures electrical enclosures at its facilities in Portland, Oregon and Modesto, California.
Strut and pipe support systems are metal frameworks and related accessories used in industry to support pipes, lighting fixtures and conduit. Strut systems can be easily assembled with bolts and spring-loaded nuts, eliminating the necessity of drilling or welding associated with other types of frameworks. B-Line manufactures and sells a wide variety of components for these systems, including steel struts rolled from coils, stamped steel fittings for interconnecting struts, shelf-supporting brackets, pipe and conduit supporting clamps, and accessories for the installation of strut systems on location. Pipe hangers are generally used in conjunction with strut systems to support heavy and light duty piping runs in the mechanical, plumbing and refrigeration industry. The principal materials used by B-Line in manufacturing are coils of steel and extruded aluminum which B-Line purchases from a number of suppliers. No one supplier is essential to B-Line's production. A limited number of components for strut and pipe support systems, including bolts and nuts and certain forged and cast components, are purchased from numerous sources and sold by B-Line as accessories to its own manufactured products.
Cable tray systems are continuous networks of ventilated or solid trays used primarily in the routing of power cables and control wiring in power plant or industrial installations. The systems are generally hung from ceilings or supported by strut frameworks. Cable tray is produced from either extruded aluminum or roll-formed steel in various configurations to offer versatility to designers and installers. Non-metallic strut and cable tray products, which are used primarily in corrosive environments, are also available.
Telecommunications equipment racks and cable runways are manufactured from aluminum or steel. The systems are installed in the central offices of telephone operating companies. As switching equipment is changed and upgraded, the systems are replaced.
Electrical enclosures are metal enclosure boxes, generally manufactured with steel, that are used to contain and protect electric meters, fuse and circuit breaker boards and electrical panels. These products are used in industrial, commercial and residential installations.
B-Line also manufactures a line of lightweight support fasteners to be used in commercial and industrial facilities to attach electrical and acoustical fixtures.
B-Line sells primarily to electrical, mechanical and telecommunications wholesalers. Products are marketed directly by district sales offices and by regional sales managers through independent manufacturers' representatives. Products are shipped to customers from the Highland and Troy, Illinois; Norcross, Georgia; Reno, Nevada; Portland, Oregon; and Modesto and Santa Fe Springs, California plants, from two regional warehouses and 42 consigned stock locations. B-Line's products are advertised in trade journals and by circulation of comprehensive catalogs.
(c) Competition.
Substantial competition exists in all the Company's marketing and production areas. Although no comprehensive statistics are available, the Company believes it is a major supplier of organic chemicals and biochemicals for research and for diagnostic testing procedures involving enzymes and of chromatography products for analyzing and separating complex chemical mixtures. A few competitors, like the Company, offer thousands of chemicals and stock and analyze most of their products. While the Company generally offers a larger number of products, some of the Company's products are unusual and have relatively little demand. In addition, there are many competitors who offer a limited quantity of chemicals, and several companies compete with the Company by offering thousands of chemicals although few of them stock or analyze substantially all of the chemicals they offer for sale.
The Company believes its B-Line subsidiary to be among the three largest producers of metal strut framing, pipe hangers and cable tray component systems, although reliable industry statistics are not available.
In all product areas the Company competes primarily on the basis of customer service, quality and price.
(d) Employees.
The Company employed 5,110 persons as of December 31, 1993. Of these, 4,198 were engaged in production and distribution of chemical products. The B-Line subsidiary employed 912 persons. The total number of persons employed within the United States was 3,792, with the balance employed by the foreign subsidiaries. The Company employed over 1,400 persons who have degrees in chemistry, biochemistry, engineering or other scientific disciplines, including approximately 235 with Ph.D. degrees.
Employees engaged in chemical production, research and distribution are not represented by any organized labor group. B-Line's production workers at the Highland and Troy, Illinois facilities are members of the International Association of Machinists and Aerospace Workers, District No. 9 (AFL-CIO). The labor agreement covering these employees expires November 12, 1995. B-Line's production workers at the Norcross, Georgia facility are members of the United Food and Commercial Workers International (AFL-CIO), Retail Clerks Union Local 1063. The labor agreement covering these employees expires June 11, 1994.
(e) Back-log of Orders.
The majority of orders for chemical products in laboratory quantities are shipped from inventory, resulting in no back-log of these orders. However, individual items may occasionally be out of stock. These items are shipped as soon as they become available. Some orders for larger-than-normal laboratory quantities are for future delivery. On December 31, 1993 and 1992, the back-log of firm orders and orders for future delivery of chemical products was approximately $9,100,000 and $6,800,000, respectively. The Company estimates that substantially all of the December 31, 1993, back-log will be shipped during 1994.
On December 31, 1993 and 1992, B-Line had a back-log of orders amounting to $2,400,000 and $2,200,000, respectively. B-Line estimates that substantially all of the December 31, 1993, back-log will be shipped during 1994.
