                                     PART I
 
ITEM 1. BUSINESS
 
     The Company. Kellogg Company, incorporated in Delaware in 1922, and its
subsidiaries are engaged in the manufacture and marketing of ready-to-eat cereal
and other grain-based convenience food products on a worldwide basis. The
address of the principal business office of Kellogg Company is One Kellogg
Square, P.O. Box 3599, Battle Creek, Michigan 49016-3599. Unless otherwise
indicated by the context, the term "Company" as used in this report means
Kellogg Company, its divisions and subsidiaries.
 
     Financial Information About Segments. The information called for by this
Item is incorporated herein by reference from Note 13 to the Consolidated
Financial Statements on pages 31 and 32 of the Company's Annual Report.
 
     Principal Products. The principal products of the Company are ready-to-eat
cereals and other convenience food products which are manufactured in 20
countries and distributed in more than 160 countries. The Company's products are
generally marketed under the KELLOGG'S(R) name and are sold principally to the
grocery trade through direct sales forces for resale to consumers. The Company
uses broker and distribution arrangements for certain products as well as in
less developed market areas. Additional information pertaining to the relative
sales of ready-to-eat cereals and the Company's other convenience food products
is found in Note 13 to the Consolidated Financial Statements on pages 31 and 32
of the Company's Annual Report.
 
     Other Convenience Food Products. In the United States and Canada, in
addition to ready-to-eat cereals, the Company produces and distributes toaster
pastries, bagels, frozen waffles, crispy marshmallow squares, and cereal bars.
The Company also markets these and other convenience food products in various
locations throughout the world.
 
     Raw Materials. Agricultural commodities are the principal raw materials
used in the Company's products. World supplies and prices of such commodities
are constantly monitored, as are government trade policies. The cost of raw
materials may fluctuate widely due to government policy and regulation, weather
conditions, or other unforeseen circumstances. Continuous efforts are made to
maintain and improve the qualities and supplies of raw materials for purposes of
the Company's short-term and long-term requirements.
 
     The principal ingredients in the products produced by the Company in the
United States include corn grits, oats, rice, various fruits, sweeteners, wheat,
and wheat derivatives. Ingredients are purchased principally from sources in the
United States. In producing toaster pastries, bagels, frozen waffles, and cereal
bars, the Company may use flour, shortening, sweeteners, dairy products, eggs,
fruit, and other filling ingredients, which ingredients are obtained from
various sources. Although the Company enters into some long-term contracts, the
bulk of such raw materials are purchased on the open market. While the cost of
raw materials may increase over time, the Company believes that it will be able
to purchase an adequate supply of such raw materials as needed. The Company also
uses commodity futures and options to hedge some of its raw material costs.
Refer to Note 11 to the Consolidated Financial Statements contained in the
Company's Annual Report on page 30.
 
     Raw materials and packaging needed for internationally based operations are
available in adequate supply and are sometimes imported from countries other
than those where used in manufacture.
 
     Cereal processing ovens at major domestic and international facilities are
regularly fueled by natural gas or propane obtained from local utilities or
other local suppliers. Short-term standby propane storage exists at several
plants for use in the event of interruption in natural gas supplies.
Additionally, oil may be used to fuel certain plant operations in the event of
natural gas shortages at various plants or when its use presents economic
advantages.
 
     Trademarks and Technology. Generally, the Company's products are marketed
under trademarks owned by the Company. The Company's principal trademarks are
its housemark, brand names, slogans, and designs related to cereals and other
convenience food products manufactured and marketed by the Company. These
 
                                        2

     The slogans "The Best To You Each Morning"(R), "The Original and Best(R),"
and "They're Gr-r-reat!"(R), used in connection with the Company's ready-to-eat
cereals, are also important Company trademarks. The Company's use of the
advertising themes "Better Breakfast"(TM), "Get A Taste For The Healthy
Life"(TM), and "Cereal...Eat It For Life"(TM) represent part of its effort to
establish throughout the United States and the world the concept of a nutritious
breakfast.
 
     The Company considers that, taken as a whole, the rights under its various
patents, which expire from time to time, are a valuable asset, but the Company
does not believe that its businesses are materially dependent on any single
patent or group of related patents. The Company's activities under licenses or
other franchises or concessions are not material.
 
     Seasonality. Demand for the Company's products is approximately level
throughout the year.
 
     Working Capital. Although terms vary around the world, in the United States
the Company generally requires payment for goods sold eleven days subsequent to
the date of invoice, with a 2% discount allowed for payment within ten days.
Receipts from goods sold, supplemented as required by borrowings, provide for
the Company's payment of dividends, capital expansion, and for other operating
expenses and working capital needs.
 
     Customers. The Company is not dependent on any single customer or a few
customers for a material part of its sales. Products of the Company are sold
through its own sales forces and through broker and distributor arrangements and
are generally resold to consumers in retail stores, restaurants, and other food
service establishments.
 
     Backlog. For the most part, orders are filled within a few days of receipt
and are subject to cancellation at any time prior to shipment. The backlog of
any unfilled orders at any particular time is not material to the Company.
 
     Competition. The Company has experienced intense competition for sales of
all of its principal products in its major markets, both domestically and
internationally. The Company's products compete with advertised and branded
products of a similar nature as well as unadvertised and private label products,
which are typically distributed at lower prices, and generally with other food
products with different characteristics. Principal methods and factors of
competition include new product introductions, product quality, composition and
nutritional value, price, advertising, and promotion.
 
                                        3

     Research and Development. Research to support and expand the use of the
Company's existing products and to develop new food products is carried on at
the W.K. Kellogg Institute for Food and Nutrition Research in Battle Creek,
Michigan, and at other locations around the world. The Company's expenditures
for research and development were approximately $121.9 million in 1998, $106.1
million in 1997, and $84.3 million in 1996.
 
     Environmental Matters. The Company's facilities are subject to various
foreign, federal, state, and local laws and regulations regarding the discharge
of material into the environment and the protection of the environment in other
ways. The Company is not a party to any material proceedings arising under these
regulations. The Company believes that compliance with existing environmental
laws and regulations will not materially affect the financial condition or the
competitive position of the Company. The Company is currently in substantial
compliance with all material environmental regulations affecting the Company and
its properties.
 
     Employees. At December 31, 1998, the Company had 14,498 employees.

other countries. The Company's plants have been designed and constructed to meet
its specific production requirements, and the Company periodically invests money

sufficient capacity for its current operations.
