Exhibit 99.1 -- 2001 Quarterly Data (Unaudited)
THIS DATA IS BEING PROVIDED IN ANTICIPATION OF CERTAIN ACCOUNTING CHANGES
THAT WILL BE REFLECTED IN McCORMICK & CO.'S FINANCIAL REPORTING IN FISCAL YEAR
2002. THE DATA BELOW INDICATES THE IMPACT OF THESE UPCOMING CHANGES FOR EACH
QUARTER AND THE FULL YEAR OF FISCAL 2001, AS IF THE CHANGES HAD BEEN IN EFFECT
DURING THAT PERIOD. THE ACCOUNTING CHANGES ARE DESCRIBED HERE:
In November 2001, the EITF issued EITF 01-09, "Accounting for
Consideration Given by a Vendor to a Customer or a Reseller of the Vendor's
Products," which is a codification of EITF's 00-14, 00-22 and 00-25. This
will require the Company to reclassify certain marketing expenses as a
reduction of sales. Concurrent with the adoption of EITF 01-09, the Company
is also reclassifying certain expenses from selling, general and
administrative expense to cost of goods sold. These reclassifications will
take place in the first quarter of fiscal 2002 and prior periods will be
reclassified. The effect of these reclassifications on 2001 will be a
decrease to sales of $153.9 million, an increase in cost of goods sold of
$20.0 million, and a decrease in selling, general and administrative expenses
of $173.9 million. These reclassifications will decrease gross profit margin
as a percentage of sales from 40.9% to 35.9% and increase operating income as
a percentage of sales from 10.1% to 10.8% in 2001. These reclassifications
will not impact net income.
In June 2001, the Financial Accounting Standards Board (FASB) issued
Statements of Financial Accounting Standards (SFAS) No. 141, "Business
Combinations," and No. 142, "Goodwill and Other Intangible Assets." SFAS No.
141 applies to all business combinations with a closing date after June 30,
2001. This statement eliminates the pooling-of-interest method of accounting,
and further clarifies the criteria for recognition of intangible assets
separately from goodwill. Under SFAS No. 142, goodwill and indefinite lived
intangible assets will no longer be amortized but will be subject to annual
impairment tests in accordance with the new standard. Separate intangible
assets that have finite lives will continue to be amortized over their useful
lives. The Company will adopt SFAS No. 142 effective December 1, 2001. No
goodwill impairment will result upon adoption. The Company recorded $13.0
million of goodwill amortization expense ($12.2 after tax) for the year ended
November 30, 2001.

Fiscal 2001 financial results will not be restated for the amortization of
goodwill. Had the accounting change been in effect for the fiscal year 2001,
selling, general and administrative expense would have been reduced by $13.0
million. The after-tax impact of the accounting change would have been $12.2
million.
