                  BASF Makes a Strong Start to 2005


    LUDWIGSHAFEN, Germany--(BUSINESS WIRE)--April 28, 2005--

    --  Sales grow strongly due to higher volumes and prices

    --  EBIT before special items up 33 percent

    --  Cash flow increases further

    --  Outlook for full year 2005 remains positive

    In the first quarter of 2005, BASF's (NYSE:BF) (FWB:BAS) (LSE:BFA)
performance followed on smoothly from the very good fourth quarter of
2004. "We are constantly improving our portfolio according to the
motto 'Building strengths and eliminating weaknesses.' This creates
the conditions that are needed to ensure that we will continue to earn
a premium on our cost of capital in the future," said Dr. Juergen
Hambrecht, Chairman of the Board of Executive Directors, when
commenting on the company's first-quarter figures at BASF's 53rd
Annual Meeting on April 28, 2005. The good first quarter gives
Hambrecht grounds for optimism: "Demand for our products remains
strong. We are attempting to counter very high raw materials costs,
which are continuing to rise in some cases, with further price
increases. We are also rigorously implementing our restructuring
measures to ensure our long-term competitiveness."
    First-quarter sales increased by 11 percent compared with the
strong first quarter of 2004 to over EUR 10 billion. Growth was
primarily due to price increases. Sales volumes were higher than in
the first quarter of 2004, in particular in the Chemicals and Plastics
segments. Sales rose by 14 percent if divestitures and currency
fluctuations are not taken into account.
    Compared with the previous year, income from operations (EBIT)
before special items climbed 33 percent to EUR 1.6 billion. In the
Chemicals and Plastics segments, where capacity utilization was
predominantly high, there was a significant improvement in margins and
earnings. The Performance Products segment increased earnings despite
the divestiture of the printing systems business. Further reductions
in fixed costs contributed to the positive earnings trend throughout
the chemical businesses. Earnings in the Agricultural Products &
Nutrition segment declined slightly due to unsatisfactory
profitability in the Fine Chemicals division. In the Oil & Gas
segment, earnings benefited from high oil prices.
    First-quarter EBIT after special items rose 39 percent to EUR 1.5
billion. Special items were related to various restructuring measures
that are recorded under "Other" until implementation in the course of
the year.
    The financial result improved in particular due to higher earnings
from the stake in the Basell joint venture, which BASF is planning to
divest. Income before taxes and minority interests increased by 49
percent to EUR 1.5 billion.
    The tax rate was 40 percent compared with 47 percent in the first
quarter of 2004. The decline was due to the higher contribution to
earnings from the NAFTA region. In addition, a charge for the tax
effect of planned dividend distributions from Group companies was
included in the first quarter of 2004. Income taxes contain taxes for
oil production that are noncompensable with German corporate income
tax. These oil production taxes increased from EUR 138 million to EUR
198 million due to higher income from operations from the exploration
for and production of oil.
    Compared with the first quarter of 2004, net income climbed 66
percent to EUR 861 million. Earnings per share in the first quarter
were EUR 1.60 compared with EUR 0.94 in the same period of the
previous year.

    Outlook for 2005 remains positive

    In 2005, Hambrecht continues to expect global chemical production
to grow by approximately 3 percent, although the growth is likely to
vary widely from region to region.
    The company has increased its forecast for the average price of
Brent crude oil from $35 to $45 per barrel; its forecast for the
average euro/dollar exchange rate remains unchanged at $1.30 per euro.
    The strong start in the first quarter gives Hambrecht grounds for
optimism. The company expects higher sales and to follow on from the
high level of EBIT before special items (IFRS) posted in 2004, if
possible exceeding it. Uncertain factors continue to be the
development of oil prices and the U.S. dollar, as well as the
political situation in regional troublespots.
    Sales increase in all regions - North America triples EBIT before
special items
    Companies in Europe increased sales by 8 percent in the first
quarter of 2005. EBIT before special items rose by EUR 222 million to
EUR 1.1 billion. This was due in particular to higher margins and a
further reduction of fixed costs in the Chemicals and Plastics
segments.
    In Germany, the increase in sales and earnings was due to the
improvement in the Oil & Gas segment.
    In North America (NAFTA), sales by location of company improved by
24 percent in dollar terms. EBIT before special items tripled from EUR
90 million to EUR 271 million. All segments contributed to this
growth. The Chemicals segment performed particularly strongly due to
good capacity utilization of the steam cracker in Port Arthur, Texas,
combined with favorable margins for cracker products. The Agricultural
Products division also posted significantly higher earnings as a
result of strong demand for fungicides.
    In Asia Pacific, companies increased sales in local currency terms
by 19 percent. The sales growth was due in particular to MDI and
polyurethanes systems in the Polyurethanes division. The new plant for
PolyTHF(R) in Caojing, China, successfully started operations, and
this will be followed by the THF plant in the second quarter. At the
Verbund site in Nanjing, China, the startup of the world-scale plants
is also proceeding according to schedule. EBIT before special items
was negatively impacted by startup costs for the two new sites.
    In South America, Africa, Middle East, sales by location of
company increased by 4 percent in local currency terms. EBIT before
special items declined by EUR 7 million to EUR 71 million. In South
America, sales and earnings in the Agricultural Products division did
not reach the previous year's very strong level because dry weather
reduced demand for fungicides. The Plastics and Performance Products
segments posted higher sales and earnings.
    BASF is the world's leading chemical company: The Chemical
Company. Its portfolio ranges from chemicals, plastics, performance
products, agricultural products and fine chemicals to crude oil and

Perfect silicon disks

    Modern computers have little room to spare with as many as a
billion transistors per square centimeter jostling for position on
their processors and memory chips. Imagine the entire population of
India holidaying in Washington DC and you'll have some idea of the
density. What makes it possible is that transistors are so small. And
that, in fact, is the biggest challenge in their production. Circuits
this tiny can be paralyzed by a particle smaller than a flu virus. A
single misplaced atom may render a chip useless.

Microchip production is complicated

    More than 600 working steps are required to turn the raw material,
quartz sand, into a modern processor. Most of these steps require the
use of special chemicals, for example to clean and etch silicon chips.
"BASF is a leading manufacturer of electronic chemicals," says Claus
Poppe, Director Global Business Management for Electronic Chemicals.
"At least one BASF product was used in the production of any microchip
manufactured today." The first step is to get silicon (the building
material for most microchips) from simple quartz sand. To clean the
"dirty" silicon produced, technicians convert it into a clear liquid
that is easily purified by multiple distillations. The much cleaner
silicon emerging from this process is ready for the next step, in
which specialists use the Czochralski method to grow impressive shiny
silver crystals up to two meters tall with a perfect interior
structure. Special saws cut these crystals into paper-thin wafers that
form the basis of microchip production, but they need to be smoothed
down first and polished to a shine. Again, a number of high-purity
BASF chemicals such as nitric acid, sulfuric acid and hydrochloric
acid are used for the polishing and cleaning process. The finished
wafers are round disks measuring up to 30 centimeters across. Their
surface has to be absolutely perfect. The tolerance for irregularities
is limited to one fifty-thousandth of the diameter of a human hair.
When computers were first produced, technicians were able to solder
transistors by hand. Today's tiny circuits call for a different
technique. The modern technology for etching transistors onto wafers
is called photo-lithography. In this process, specialists first apply
a barrier layer to the silicon which they illuminate through a mask.
The layer dissolves at the sites exposed to light and the underlying
silicon layer is etched. Chip manufacturers treat the etched locations
with chemicals and repeat the process a number of times, building up
transistors layer by layer, like building houses from layers of
blocks. But dirt is everywhere. Metal devices invariably give off
unwanted atoms. Humans transmit impurities by a mere touch or breath.
That's not counting the approximately half a billion particles of dust
floating around a normal room. For this reason every step of chip
manufacture takes place in pristine working areas where all the
furnishings are plastic and filters are installed to remove the last
particle of dust from the ambient air. Anyone entering these
facilities must wear a full set of protective gear including gloves
and a face mask. "Finished microchips must be absolutely free of
contaminants, so the chemicals that are used in their manufacture have
to be extremely pure," explains Dr. Karl-Rudolf Kurtz, head of BASF's
Electronic Materials business unit. "BASF currently supplies around 30
chemicals of electronic grade purity." BASF is equipped with cleanroom
labs to check the chemicals' purity before they are delivered to chip
manufacturers. "We have the technology to detect impurities in trace
amounts of less than one microgram per tonne of product."

The Prospects

    BASF is a leading supplier of chemicals to the semiconductor
industry. The global electronic chemical business acquired from Merck
KGaA at the start of 2005 significantly strengthens BASF's market
position. Electronic chemicals distribution is organized in a global
business management system for easier ordering and shorter delivery
times. BASF was conferred the UK gas supplier BOC Edwards' Supplier
Quality Award for the reliability and quality of its electronic gases
hydrogen chloride and ammonia. BASF is also the world's only supplier
of hydroxylamine free base, a highly active solvent for cleaning
microchips.


BASF Group Business Review and Outlook

-  Sales grow strongly due to higher volumes and prices
-  EBIT before special items up 33%
-  Cash flow increases further
-  Outlook for full year 2005 remains positive

Sales

    We increased sales in the first quarter of 2005 by 11% compared
with the same period of 2004 to EUR10.1 billion. Growth was primarily
due to price increases. Sales volumes were higher than in the strong
first quarter of 2004, in particular in the Chemicals and Plastics
segments. Sales rose by 14% if divestitures and currency fluctuations
are not taken into account.

               2004         1,394

    The Chemicals and Plastics segments increased sales as a result of
overall strong volumes and higher sales prices.

    The Performance Products segment also benefited from increased
sales prices, although the loss in sales following the divestiture of
the printing systems business could not be compensated for completely.
Sales in the Agricultural Products & Nutrition segment declined due to
weather conditions and lower sales prices in the Fine Chemicals
division. The Oil & Gas segment posted the strongest sales growth in
percentage terms as a result of high oil prices.

    Earnings

    Compared with the previous year, we increased income from
operations (EBIT) before special items by 33% to EUR1,563 million.

    In the Chemicals and Plastics segments, where capacity utilization
was predominantly high, there was a significant improvement in margins
and earnings. The Performance Products segment increased earnings
despite the divestiture of the printing systems business. Further
reductions in fixed costs contributed to the positive earnings trend
throughout the chemical businesses. Earnings in the Agricultural
Products & Nutrition segment declined slightly due to unsatisfactory
profitability in the Fine Chemicals division. In the Oil & Gas
segment, earnings benefited from high oil prices.

    First-quarter EBIT after special items climbed 39% to EUR1,499
million. Special items were related to various restructuring measures
that are recorded under "Other" until implementation in the course of
the year.

    The financial result improved in particular due to higher earnings
from our stake in the Basell joint venture, which we are planning to
divest. We increased income before taxes and minority interests by 49%
to EUR1,544 million.

                    2004       343


    The tax rate was 40% compared with 47% in the first quarter of
2004. The decline was due to the higher contribution to earnings from
the NAFTA region. In addition, a charge for the tax effect of planned
dividend distributions from Group companies was included in the first
quarter of 2004. Income taxes contain taxes for oil production that
are noncompensable with German corporate income tax. These oil
production taxes increased from EUR138 million to EUR198 million due
to higher income from operations from the exploration and production
of oil.

    Compared with the first quarter of 2004, net income climbed 66% to
EUR861 million. Earnings per share in the first quarter were EUR1.60
compared with EUR0.94 in the same period of the previous year.


Outlook

    We continue to expect global chemical production to grow by
approximately 3% in 2005, although the growth is likely to vary widely
from region to region.

    We have increased our forecast for the average price of Brent
crude from $35 to $45 per barrel; our forecast for the average
euro/dollar exchange rate remains unchanged at $1.30 per euro.

    Demand for our products remains strong. We are attempting to
counter very high raw materials costs, which are continuing to rise in
some cases, with further price increases in accordance with our "value
over volume" concept. The major highlight in the further course of the
year will be the startup of our new Verbund site in Nanjing, China. We
are rigorously implementing our restructuring measures to ensure our
long-term competitiveness. The strong start in the first quarter gives
us grounds for optimism. We expect to achieve higher sales and follow
on from the high level of EBIT before special items (IFRS) posted in
2004, if possible exceeding it. Uncertain factors continue to be the
development of oil prices and the U.S. dollar, as well as the
political situation in regional troublespots.

    Significant events

    Starting from January 1, 2005, the accounting and reporting of the
BASF Group is performed according to International Financial Reporting
Standards (IFRS). The previous year's figures have been restated; the
effects of the changes are explained on page 15 ff.

    On April 11, BASF and its partner Gazprom announced a memorandum
of understanding to further strengthen their partnership. The two
partners will jointly develop the Yushno Russkoje natural gas field in
western Siberia and jointly participate in the construction of the
planned North European Gas Pipeline (NEGP) across the Baltic Sea. In
addition, Gazprom will increase its stake in the WINGAS joint venture
from currently 35%, and will thus become more heavily involved in the
joint marketing of natural gas in Europe.

    On April 15, BASF acquired the electronic chemicals business of
Merck KGaA, Darmstadt, Germany. The acquisition includes production
sites and distribution centers for high-purity chemicals in Asia and
Europe. As of this date, these activities will be assigned to the
Inorganics division of the Chemicals segment and reported accordingly.

    On April 19, BASF announced that it would continue with its share
buyback program, and plans to buy back shares for EUR1.5 billion in
2005.

All divisions increased sales and earnings. Price increases to
pass on higher raw materials costs were the prime reason for the rise
in sales to EUR1.8 billion (volumes 5%, portfolio 1%, prices 12%,
currencies -3%). Earnings increased significantly, in particular due
to improved margins, high capacity utilization and a further reduction
in fixed costs.

   Inorganics

    Strong demand for our inorganic specialties, electronic chemicals
and catalysts led to an increase in sales. We also improved earnings
due to our measures to reduce fixed costs, for example the use of new
production technologies for basic chemicals. By acquiring the
electronic chemicals business of Merck KGaA, we are further expanding
our activities in this high-growth business area.

    Petrochemicals

    Sales climbed significantly thanks to price increases in all
product lines, in particular for cracker products. We benefited from
strong demand for plasticizers and solvents. As a result of higher
margins and very good capacity utilization, earnings increased
considerably compared with the same period of 2004. Raw materials
costs remain extremely high. In the second quarter, we will start
operations at the steam cracker and further world-scale plants at our
Verbund site in Nanjing, China.

    Intermediates

    The previous year's positive trend with regard to sales volumes
and prices continued in Europe and North America (NAFTA). Demand for
butanediol and its derivatives was particularly strong. We achieved
higher margins and earnings by further increasing prices. We
successfully started operations at our new plant for PolyTHF(R) in
Caojing, China. PolyTHF(R) is an important precursor for elastic
fibers used, for example, in sportswear.


Plastics

-         Strong sales growth primarily due to price increases
-         Earnings climb 74%
-         Portfolio further optimized

    Sales again rose significantly due to higher prices and sales
volumes (volumes 3%, prices 20%, currencies -2%). Earnings in the
Performance Polymers and Polyurethanes divisions increased
considerably. In the Styrenics division, earnings were below the level
of the first quarter of 2004.

    Styrenics

    Higher sales prices led to an increase in sales, but this did not
compensate for the significant increase in the cost of the division's
most important raw material, benzene. This margin pressure resulted in
a decline in earnings. We intend to improve profitability by
increasing prices and by further optimizing the portfolio.

    Performance Polymers

    Sales growth resulted from continuous price increases throughout
the product portfolio and expansion of the engineering plastics
business. Earnings increased significantly. This was due primarily to
the realization of synergies from the integration of the engineering
plastics businesses acquired in prior years as well as the
optimization of production, in particular in Europe and North America
(NAFTA).

    In the United States, our customer Mann + Hummel Inc. named BASF
"Perfect Supplier 2004."

    In Asia, we intend to strengthen our engineering plastics business
with a new compounding plant in Shanghai, China, and by expanding the
compounding plant in Pasir Gudang, Malaysia.

    Polyurethanes

    Sales increased considerably in all regions. High prices for
important raw materials were passed on to the market in the form of
price increases, thus allowing the division to achieve further
profitable growth. The expansion of MDI capacity at the site in
Antwerp, Belgium, from 360,000 to 450,000 metric tons per year is
scheduled for completion in early May 2005.


Performance Products

-         Higher sales from ongoing business
-         Profitable growth in Functional Polymers boosts earnings
-         Closer cooperation with customers on innovative products

    Sales from ongoing business increased by 5% compared with the
previous year due to higher prices (volumes -1%, portfolio -6%, prices
8%, currencies -2%). Earnings also improved.

    Performance Chemicals

    The decline in sales was due to the divestiture of the printing
systems business in the fourth quarter of 2004. Sales from ongoing
business increased, in particular due to the contribution from
performance chemicals for detergents and formulators and for the
automotive and oil industry. Earnings were slightly lower due to the
divestiture of the printing systems business. On the basis of ongoing
business, however, earnings increased, thanks to a reduction in fixed
costs.

    Coatings
 
    Sales were below the previous year's level due to a decline in
sales of automotive coatings. Together with a further increase in raw
materials costs, this resulted in a decline in earnings. The
profitability of the industrial coatings business developed positively
due to streamlining of the portfolio and optimization of production.

    We have further extended our cooperation with key customers. For
example, we act as a system supplier to BMW in China. In the important
Japanese automobile market, we have further strengthened our position
by acquiring our partner's shares in the joint venture BASF NOF
Coatings.

    Functional Polymers

    We grew profitably and faster than the market due to our
innovative product portfolio and close cooperation with our customers.
Sales increased significantly, in particular for acrylic monomers,
dispersions for architectural coatings, carpet coatings and paper
dispersions. Earnings also increased significantly because we passed
on higher raw materials costs to the market by increasing our sales
prices. We achieved the strongest earnings growth in North America
(NAFTA). We have added cyclohexyl methacrylate (CHM) - a special
acrylate to improve automotive coatings - to our product portfolio,
and have successfully started production at our Ludwigs-hafen site.

    The slight decline in sales (volumes -3%, prices 2%, currencies
-1%) was primarily due to weather conditions which reduced the use of
crop protection products in Europe and South America. This was
partially offset by significantly higher demand for fungicides in
North America, where our customers are preparing to combat Asian
soybean rust. A higher value product portfolio and improved cost
structures led to a further increase in earnings.

    We are currently working to develop six new crop protection active
ingredients, on a new herbicide tolerance project and on products to
protect seeds with established active ingredients. These product
innovations have a total peak sales potential of EUR700 million and
will be ready for market in the coming years. A further seven crop
protection active ingredients with peak sales of EUR1 billion are
currently being introduced to the market. We have one of the most
promising pipelines in the industry.

    The decline in sales (volumes -1%, portfolio -2%, prices -10%,
currencies -1%) was primarily due to the severe decline in the price
of lysine, the highest volume product in our portfolio. In addition,
sales volumes of pharmaceutical active ingredients and premixes were
lower than in the first quarter of 2004. Organic acids and aroma
chemicals, however, continued to grow strongly. Earnings declined due
to the overall negative trend in sales volumes and prices. To some
extent, the decline was offset by the reduction of fixed costs. We are
addressing the challenging competitive environment through active
portfolio management, further cost-reduction measures, a closer focus
on innovative products as well as close cooperations with our
customers.

    The considerable increase in oil prices in terms of both dollars
and euros compared with the same period of 2004 resulted in
significantly higher sales (volumes 4%, prices/currencies 28%).

    In the exploration and production business sector, production was
slightly higher than in the first quarter of 2004 due to increased oil
production in Libya and slightly higher gas volumes.

    At EUR36.30 per barrel, the average price of Brent crude was 42%
higher than in the same period of the previous year, resulting in a
significant increase in earnings.

    In the natural gas trading business sector, volumes increased
further and we acquired new customers. The increase in earnings was
due entirely to higher volumes. A gas supply contract was signed with
the German energy company Mark-E for a planned combined heat and power
plant.

    On April 11, 2005, we signed a memorandum of understanding with
our partner Gazprom to jointly produce natural gas in western Siberia
and market it in Europe.

    Effective January 1, 2005, companies in Asia are reported in the
region "Asia Pacific." South America, which was previously reported as
a separate region, is now reported together with the African and
Middle Eastern companies in the region "South America, Africa, Middle
East."

    Companies in Europe increased sales by 8% in the first quarter of
2005. EBIT before special items rose by EUR222 million to EUR1,134
million. This was due in particular to higher margins and a further
reduction of fixed costs in the Chemicals and Plastics segments.

    In Germany, the increase in sales and earnings was due to the
improvement in the Oil & Gas segment.

    In North America (NAFTA), sales by location of company improved by
24% in dollar terms. EBIT before special items tripled from EUR90
million to EUR271 million. All segments contributed to this growth.
The Chemicals segment performed particularly strongly due to good
capacity utilization of the steam cracker in Port Arthur, Texas,
combined with favorable margins for cracker products. The Agricultural
Products division also posted significantly higher earnings as a
result of strong demand for fungicides.

    In Asia Pacific, companies increased sales in local currency terms
by 19%. The sales growth was due in particular to MDI and
polyurethanes systems in the Polyurethanes division. The new plant for
PolyTHF(R) in Caojing, China, successfully started operations, and
this will be followed by the THF plant in the second quarter. At our
Verbund site in Nanjing, China, the startup of our world-scale plants
is also proceeding according to schedule. EBIT before special items
was negatively impacted by startup costs for our two new sites.

    In South America, Africa, Middle East, sales by location of
company increased by 4% in local currency terms. EBIT before special
items declined by EUR7 million to EUR71 million. In South America,
sales and earnings in the Agricultural Products division did not reach
the previous year's very strong level because dry weather reduced
demand for fungicides. The Plastics and Performance Products segments
posted higher sales and earnings.

    The previous year's figures were restated due to the transition to
IFRS. There were no significant changes.

    As a result of the higher level of net income, cash provided by
operating activities increased by 12% in the first quarter to EUR1,104
million. Expansion of our business resulted in an increase in
inventories and receivables. Cash used in investing activities led to
a cash outflow of EUR216 million compared with EUR602 million in the
first quarter of 2004. At EUR393 million, payments related to tangible
and intangible fixed assets were below the previous year's level and
were significantly lower than the level of amortization and
depreciation on fixed assets of EUR521 million. There was a cash
inflow due to past acquisition activities; the first quarter of 2004
contained the acquisition of Sunoco's plasticizers business.

    In cash used in financing activities, further share buybacks led
to a cash outflow. In the first quarter of 2005, 5,1 million shares
were bought back for EUR274 million or an average of EUR53.80 per
share. In the course of the year, it is planned to buy back shares for
a further EUR1.5 billion.

    Liquid funds increased by EUR716 million to EUR3,007 million, and
at EUR3,421 million financial indebtedness rose by EUR123 million
compared with the figure at the end of 2004. Net debt declined to
EUR414 million.

    Including effects of changes in valuation methods in the 2004
German GAAP annual financial statements

    Explanations of the transition in accounting and valuation methods
to IFRS The accounting and reporting of the BASF Group was done
according to German GAAP for the periods up to and including the 2004
annual financial statements. International Financial Reporting
Standards (IFRS) were taken into account to the greatest extent
possible. Due to the EU regulation enacted on July 19, 2002, BASF, as
a listed company, was required to change its reporting. Effective
January 1, 2005, BASF converted its accounting completely to IFRS in
compliance with IFRS 1 "First-time Adoption." The previous year's
figures were adjusted accordingly. Effects of this transition were
netted against equity as of January 1, 2004. Changes compared with the
prior accounting methodology are described below:


    (a) Capitalization of construction period interest 

    For qualifiying assets with a lengthy construction period,
interest on the project expenditures up to the point it is placed in
service can be capitalized. Construction period interest was
previously not capitalized, in conformance with German GAAP. According
to U.S. GAAP, capitalization of construction period interest is
required. In order to avoid a difference between IFRS and U.S. GAAP,
construction period interest is capitalized in these financial
statements. The amortization of capitalized construction period
interest reduced EBIT (first quarter 2004: EUR17 million, full year
2004: EUR64 million), whereas the capitalization of construction
period interest increased the financial result (first quarter 2004:
EUR17 million, full year 2004: EUR59 million). The assets of the
Chemicals and Plastics segments in particular increased as a result of
the capitalization.

    (b) Capitalization of internally generated intangible assets 

    This item contains costs for software that is internally developed
and used. These costs are to be capitalized and depreciated as an
intangible asset according to IFRS. German GAAP did not allow
internally generated intangible fixed assets to be capitalized. IAS 38
"Intangible Assets" covers the capitalization of development costs.
Due to the stringent capitalization requirements, there has been no
capitalization of development costs to date.

    (c) Pension accounting 

    The accounting treatment of direct pension obligations was already
performed in accordance with IAS 19 "Employee Benefits" in the 2004
annual financial statements. This led to a new valuation whereby
deferred actuarial gains and losses due to deviations from actuarial
assumptions were netted out against retained earnings. In addition,
certain pension obligations were financed via legally independent
plans, especially BASF Pensionskasse VVaG. Since BASF as the
sponsoring entity maintains guarantees, these plans are treated under
IFRS as defined benefit plans, and are to be included in the Group
financial statements. The inclusion of these pension plans was not
possible in the German GAAP financial statements. From now on, they
will be accounted for according to IAS 19, retrospective from January
1, 2004. Deferred actuarial gains and losses were not included in
accordance with the option under IFRS 1 "First-time Adoption." In
addition, the financing cost for pensions and other personnel
obligations was netted against the expected returns on plan assets
(first quarter 2004: EUR38 million, full year 2004: EUR150 million)
and shown in "Other financial results" rather than before EBIT.

(d) Accounting for provisions

These transition items contain the following differences: 

    - Under German GAAP, provisions were established for omitted
maintenance and repairs, and for mandated modifications in connection
with the operation of production facilities. According to IFRS, these
items are to be expensed as incurred. - Provisions for certain
environmental measures and recultivation measures have to be
capitalized under IFRS in the amount of the expected expense, thereby
increasing the acquisition costs of the affected assets. According to
German GAAP, costs were accrued over the useful life of the asset, in
contrast to IFRS, where such costs are depreciated following
capitalization. - According to German GAAP, provisions were accrued
for cyclical overhauls, which were to be carried out at specific
intervals. According to IFRS, the expenditures are to be capitalized,
and depreciated over the interval between cyclical overhauls. -
Long-term provisions are to be discounted according to IFRS, whereas
under German GAAP, they were reported at nominal value.

(e) Accounting for financial instruments

    Accounting under IFRS requires derivatives to be accounted for at
fair value and shown as other assets and liabilities on the balance
sheet. Provided that the conditions for hedge accounting are not
fulfilled, changes in the fair value will affect income, just as with
corresponding gains and losses in the underlying instrument. Gains
from swaps and forward contracts were accounted for upon maturity
under German GAAP. Unrealized losses, however, were immediately
recognized in income within other provisions. According to German
GAAP, long-term receivables and liabilities in foreign currencies were
to be valued at the initial exchange rate, or at the exchange rate on
the date of the financial statements; the lower rate in the case of
receivables, or higher rate in the case of liabilities. According to
IFRS, valuation is always made at the exchange rate on the date of the
financial statements. Available-for-sale securities are to be valued
at their fair value on the date of the financial statements. Changes
in the fair value are shown as a component of equity (Other
comprehensive income) up until the point of disposal of the
securities. In German GAAP financial statements such securities are
valued at acquisition cost, or lower fair value on the date of the
financial statements, with valuation changes immediately affecting
income.

(f) Inventory valuation

    Since the LIFO method is not allowed under IFRS, inventory
valuation method was changed for the 2004 annual financial statements
to the average cost method, which is allowed under IFRS.

    According to German GAAP, raw materials and supplies are to be
discounted based on lower replacement costs. According to IFRS,
valuation adjustments may only be made in the event of a lower net
realizable value of the inventories. (g) Elimination of goodwill
amortization, and impairment-only approach Goodwill was formerly
amortized over its expected useful life, according to German GAAP.
According to IFRS 3 "Business Combinations," goodwill is to be
examined annually in accordance with IAS 36 "Impairment of Assets" to
determine if a write-down is necessary. Due to IFRS 1 "First-time
Adoption," in conjunction with IFRS 3 "Business Combinations," annual
amortization is no longer permitted effective January 1, 2004.
According to impairment tests carried out at the transition date and
at year-end 2004, impairment write-downs were not necessary. In
particular, earnings in the Agricultural Products division improved as
a result of the elimination of goodwill amortization (first quarter of
2004: EUR25 million, full year 2004: EUR96 million).

    (h) Other adjustments 

    These relate primarily to the treatment of investment subsidies
that may not be immediately credited to income according to IFRS, but
instead reduce the acquisition costs of the respective assets, as well
as to reclassifications in the income statement.

    (i) Tax effects of planned dividend distributions and other tax
effects 

    According to IFRS, in 2004, based on the updated financial plan
and taking into account a change in German corporate income tax law
(Section 8b KStG), deferred taxes were accrued for the tax effects of
planned dividend distributions from Group companies.

    (j) Valuation adjustments for companies accounted for under the
equity method 

    The IFRS valuation adjustments especially concern the
capitalization and amortization of internally developed and used
software, as well as construction period interest for companies
accounted for under the equity method. Due to the valuation
adjustments, the book value of these financial assets as of January 1,
2004 was higher under IFRS than under German GAAP. The negative
reconciliation item to net income under ifrs was associated with
write-downs on these financial assets.

    Changes in presentation

    Presentation of the income statement and balance sheet is made in
accordance with IAS 1 "Presentation of Financial Statements." Certain
individual items were combined for clarity, and detailed separately
only in the Notes to the Consolidated Financial Statements:

    - Balance sheet

    IFRS requires a differentiation between long and short-term
assets, in contrast to German GAAP, where a breakdown by fixed assets
versus current assets was required. The item "Investments accounted
for using the equity method" contains, in particular, the stake in the
Basell joint venture that is scheduled for divestiture. In equity, the
new item "Other Comprehensive Income" is presented to account for
changes that do not affect income. The option under IFRS 1 to net the
translation adjustment against retained earnings and net profit as of
January 1, 2004 was exercised. Liabilities are segmented according to
maturity under IFRS, whereas under German GAAP it was segmented by
provisions and liabilities.

    - Income statement

    Financing costs for pensions and other personnel obligations
netted against the expected returns from plan assets are presented in
an item "Other financial results" according to IFRS, rather than
before EBIT. This item also contains the capitalization of
construction period interest, the discounting of other provisions as
well as changes in fair value of interest derivatives.
