Item 1.  Business
         --------

General Development of Business
-------------------------------

      Lancaster Colony Corporation was reincorporated in Ohio effective January
2, 1992. Prior to this date Lancaster Colony Corporation had been a Delaware
Corporation organized in 1961. As used herein the term "registrant," unless the
context otherwise requires, refers to Lancaster Colony Corporation and its
subsidiaries.

Description of and Financial Information About Business Segments
----------------------------------------------------------------

      The registrant operates in three business segments - "specialty foods,"
"glassware and candles" and "automotive" - which accounted for approximately
42%, 35% and 23%, respectively, of consolidated net sales for the fiscal year
ended June 30, 1999. The financial information relating to business segments for
each of the three years in the period ended June 30, 1999, appearing in Exhibit
13 in this Form 10-K Annual Report, is incorporated herein by reference. Further
description of each business segment the registrant operates within is provided
below:

                                 Specialty Foods
                                 ---------------

      The food products manufactured and sold by the registrant include salad
dressings and sauces marketed under the brand names "Marzetti," "Cardini's,"
"Pfeiffer" and "Girard's"; fruit glazes, veggie dips and fruit dips marketed
under the brand name "Marzetti"; frozen unbaked pies principally marketed under
the brand name "Mountain Top"; hearth-baked frozen breads marketed under the
brand name "New York Frozen Foods"; refrigerated chip dips and dairy desserts
marketed under the brand names "Allen" and "Marzetti"; premium dry egg noodles
marketed under the brand names "Inn Maid" and "Amish Kitchen"; frozen specialty
noodles, pastas, and breaded specialty items marketed under the brand name
"Reames"; croutons and related products marketed under the brand name "Chatham
Village" and caviar marketed under the brand name "Romanoff."

      Nearly all of this segment's product lines are manufactured by the
registrant in 11 plants located throughout the United States. Certain individual
items are manufactured and packaged by third parties located in the United
States under contractual agreements established by the registrant.

      The dressings, sauces, croutons, veggie dips and fruit dips are sold in
various metropolitan areas in the United States with sales being made to retail
and/or foodservice markets.

      The frozen unbaked pies are marketed principally in the Midwestern United
States through salesmen and food brokers to institutional distributors and
retail outlets. A portion of the frozen bread sales is directed to the
foodservice market.

      The dry egg noodles and refrigerated chip dips and dairy desserts are sold
through food brokers and distributors to retail markets principally in the
Midwestern United States.

      The "Reames" line is sold through brokers and distributors in various
metropolitan areas principally in the central and Midwestern United States.

      Due to distribution arrangements with several large foodservice customers,
the sales to one foodservice distributor accounted for approximately 12% of this
segment's total net sales in the current year. Although the Company is a leading
producer in several of its product categories, all of the markets in which the
registrant sells food products are highly competitive in the areas of price,
quality and customer service.

      During fiscal year 1999, the registrant obtained adequate supplies of raw
materials for this segment.

      The registrant's firm order backlog at June 30, 1999, in this business
segment, was approximately $4,125,000 as compared to a backlog of approximately
$4,195,000 as of the end of the preceding fiscal year. It is expected that all
of these orders will be filled during the current fiscal year. The operations of
this segment are not affected to any material extent by seasonal fluctuations.
The registrant does not utilize any franchises or concessions in this business
segment. The trade names under which it operates are significant to the overall
success of this segment. However, the patents and licenses under which it
operates are not essential to the overall success of this segment.

                             Glassware and Candles
                             ---------------------

      Candles and other home fragrance products of all sizes, forms and
fragrance are primarily sold in the mass merchandise markets as well as to
supermarkets, drug stores and specialty shops under the name "Candle-lite." A
portion of the registrant's candle business is marketed under private label.

      Glass products include a broad range of machine pressed and machine blown
consumer glassware and technical glass products such as cathode ray tubes,
lighting components, lenses and silvered reflectors.

      Consumer glassware includes a diverse line of decorative and ornamental
products such as tumblers, bowls, pitchers, jars and barware. These products are
marketed under a variety of trademarks, the most important of which are "Indiana
Glass," "Colony" and "Fostoria." The registrant also purchases domestic and
imported blown glassware which is sold under the trade name "Colony."

      Glass vases and containers are sold both in the retail and wholesale
florist markets under the trade names "Brody" and "Indiana Glass" as well as
under private label.

      The registrant's glass products are sold to discount, department, variety
and drug stores, as well as to jobbers and directly to retail customers.
Commercial markets such as foodservice, hotels, hospitals and schools are also
served by this segment's products. Although minor, rubber matting sales to
commercial markets are also included in this segment. All the markets in which
the registrant sells houseware products are highly competitive in the areas of
design, price, quality and customer service. Sales of glassware and candles to
one customer accounted for approximately 24% and 21% of this segment's total net
sales during 1999 and 1998, respectively. No other customer accounted for more
than 10% of this segment's total net sales.

      During fiscal year 1999, the registrant obtained adequate supplies of raw
materials for this business segment.

      The registrant's firm order backlog at June 30, 1999, in this business
segment, was approximately $38,981,000 as compared to approximately $33,327,000
as of the end of the preceding fiscal year. It is expected that all of these
orders will be filled during the current fiscal year. Seasonal retail stocking
patterns cause certain of this segment's products to experience increased sales
in the first half of the fiscal year. The registrant does not use any franchises
or concessions in this segment. The patents under which it operates are not
essential to the overall success of this segment. However, certain trademarks
and licenses are important to this segment's marketing efforts.

                                   Automotive
                                   ----------

      The registrant manufactures and sells a complete line of rubber, vinyl and
carpeted car mats both in the aftermarket and to original equipment
manufacturers. Other products are pickup truck bed mats, running boards,
bedliners, tool boxes and other accessories for pickup trucks, vans and sport
utility vehicles, truck and trailer splash guards and quarter fenders,
accessories such as cup holders, litter caddies and floor consoles. The
automotive aftermarket products are marketed primarily through mass
merchandisers and automotive outlets under the name "Rubber Queen" and the
registrant sells bedliners under the "Protecta" trademark, running boards under
the "Dee Zee" name, as well as under private labels. The aggregate sales of two
customers accounted for approximately 29% of this segment's total net sales
during 1999 and 1998. No other customer accounted for more than 10% of this
segment's total net sales. Although the Company is a market leader in many of
its product lines, all the markets in which the registrant sells automotive
products are highly competitive in the areas of design, price, quality and
customer service.

      During fiscal year 1999, the registrant obtained adequate supplies of raw
materials for this segment.

      The registrant's firm order backlog at June 30, 1999, in this business
segment, was approximately $6,486,000 as compared to a backlog of approximately
$6,348,000 as of the end of the preceding fiscal year. Such backlogs do not
reflect certain orders by original equipment manufacturers as, due to its
nature, such information is not readily available. It is expected that all of
these orders will be filled during the current fiscal year. The operations of
this segment are not affected to any material extent by seasonal fluctuations.
The registrant does not utilize any significant franchises or concessions in
this segment. The patents, trademarks and licenses under which it operates are
generally not essential to the overall success of this segment.

Inc. totaled approximately 10% of consolidated fiscal 1999 net sales.

                            ------------------------

      The estimated amount spent during each of the last three fiscal years on
research and development activities determined in accordance with generally
accepted accounting principles is not considered material.

                              ---------------------

      Certain of the registrant's operations are subject to compliance with
various air emission standards promulgated under Title V of the Federal Clean
Air Act. Pursuant to this Act, with respect to certain of its facilities, the
Company is required to submit compliance strategies to various regulatory
authorities for review and approval. Based upon available information,
compliance with the Federal Clean Air Act provisions, as well as other various
Federal, state and local environmental protection laws and regulations, is not
expected to have a material adverse effect upon the level of capital
expenditures, earnings or the competitive position of the registrant for the
remainder of the current and succeeding fiscal year.

future based on existing operations.
