NOTES

1. BASIS OF PRESENTATION

The unaudited pro forma financial information has been compiled from underlying financial statements prepared in accordance with U.S. GAAP and IFRS and reflects the Cadbury acquisition by Kraft Foods and the divestiture of Kraft’s Pizza business.

The unaudited pro forma financial information should be read in conjunction with the underlying financial information from which it was extracted without material adjustment: (a) the audited consolidated financial statements of Kraft Foods as at and for the year ended December 31, 2009, prepared in accordance with U.S. GAAP; and (b) the audited consolidated financial statements of Cadbury as at and for the year ended December 31, 2009, prepared in accordance with IFRS.

The underlying financial information of Kraft Foods has been derived from the audited consolidated financial statements of Kraft Foods contained in Kraft Foods’ Annual Report on Form 10-K filed with the SEC on February 25, 2010. The underlying financial information for Cadbury has been derived from the audited consolidated financial statements of Cadbury for the year ended December 31, 2009 contained in this Form 8-K.

The Cadbury acquisition has been treated as an acquisition, with Kraft Foods as the acquirer and Cadbury as the acquiree, assuming that the Cadbury acquisition had been completed on January 1, 2009, for the unaudited pro forma consolidated statement of earnings and on December 31, 2009, for the unaudited pro forma consolidated balance sheet.

This unaudited pro forma financial information is not intended to reflect the financial position and results which would have actually resulted had the Cadbury acquisition been effected on the dates indicated. Further, the pro forma results of operations are not necessarily indicative of the results of operations that may be obtained in the future.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The unaudited pro forma financial information has been compiled in a manner consistent with the accounting policies adopted by Kraft Foods. These accounting policies differ in certain respects from those of Cadbury. The adjustments made to align Cadbury’s IFRS financial information with Kraft Foods’ U.S. GAAP accounting policies are described in note 3(l).

The Cadbury balances have been translated from pounds sterling to U.S. dollars using average exchange rates applicable during the periods presented for the unaudited pro forma consolidated statement of earnings and the period end exchange rate for the unaudited pro forma consolidated balance sheet.

3. OTHER PRO FORMA ADJUSTMENTS

(a) Estimated Purchase Consideration

Estimated purchase consideration and related excess purchase consideration over book value of net assets acquired are as follows (in millions):

The ordinary share portion of the estimated purchase consideration was calculated using a price of $28.36 for each share of Kraft Foods common stock based on the weighted average of the closing market price of Kraft Foods common shares on the date Cadbury shareholders tendered their shares. The number of shares of Kraft Foods common stock assumed to be issued is 261.5 million.

For purposes of preparing these pro forma financial statements, Kraft Foods has assumed that funding came from the net proceeds from the sale of the pizza business and the notes issued February 8, 2010. The cash portion of the estimated purchase consideration, payable in U.K. pounds, was translated based on an exchange rate of £1 : $1.5950 which is the weighted average of the exchange rates on the date shares were tendered to Kraft Foods.

Except as noted below, the carrying value of assets and liabilities in Cadbury’s financial statements are considered to be a proxy for the fair value of those assets and liabilities. As this allocation is based on preliminary estimates, additional adjustments to record the fair value of all assets and liabilities and adjustments for consistency of accounting policies and to reflect Cadbury under U.S. GAAP may be required.

For purposes of the pro forma analysis, the following adjustments were made to reflect our preliminary estimate of the fair value of net assets acquired:

No other adjustment was made to the assets and liabilities of Cadbury. Goodwill representing the total excess of the purchase consideration over the fair value of the assets acquired was $9,506 million. This allocation is based on preliminary estimates; the final acquisition cost allocation may differ materially from the preliminary assessment outlined above. Any changes to the initial estimates of the fair value of the assets and liabilities will be allocated to residual goodwill.

(b) Transaction Costs

We have estimated that total Cadbury acquisition related costs will be $200 million. These costs have been accrued as a current liability, net of a $20 million tax benefit. Because we are required to expense these costs as they are incurred, we have charged them to retained earnings as of December 31, 2009. No adjustment has been made to the unaudited pro forma consolidated statement of earnings for these costs as they are non-recurring.

(c) Interest Expense

An adjustment to record pro forma interest expense of $451 million was made for the year ended December 31, 2009. The interest charges are based on the weighted average interest rate on $8,646 million of the $9,500 million notes issued as if such amount was issued at January 1, 2009 and outstanding at December 31, 2009. The $8,646 million of notes issued is based on $11,129 million of cash consideration less the net proceeds of $2,483 million from the sale of the pizza business. The weighted average interest rate on these notes of 5.211% was used to calculate interest expense.

(d) Depreciation Expense

Property, plant and equipment was increased by $678 million to its fair value. Exclusive of land, the weighted average remaining useful life of these assets is estimated at 9 years. An adjustment to increase estimated depreciation expense of $14 million was made for the year ended December 31, 2009. Total annual depreciation expense after this adjustment is $360 million.

(e) Amortization Expense

Definite lived intangible assets were recorded at their fair value of $2,400 million. The weighted average useful life of the intangible assets is estimated at 15 years. An adjustment to record estimated amortization of $150 million was made for the year ended December 31, 2009. Total annual amortization expense after this adjustment is $156 million.

(f) Elimination of Cadbury Shareholders’ Equity

An adjustment to eliminate Cadbury’s Additional Paid in Capital of $378 million, Retained Earnings of $4,227 million and Accumulated Other Comprehensive Income of $1,058 million was recorded in the pro forma consolidated balance sheet at December 31, 2009. This adjustment includes the net impact of U.S. GAAP adjustments described in note 3(l)

(g) Sale of the Pizza Business

Retained earnings have been adjusted by $1,609 million for the estimated gain from the sale of the pizza business which was calculated as follows:

We have estimated that total sale related costs and other accrued expenses will be $34 million. These costs have been recorded as a deduction from the sale proceeds in determining the gain on sale.

We have assumed that income taxes were paid using proceeds from the sale.

The total net cash proceeds are assumed to be $2,483 after the payment of accrued expenses and the income tax provision. We have assumed that the proceeds were used to the decrease the borrowings used for the purchase of Cadbury.

(h) Net Revenues

Net revenues were reduced $1,632 million for the year ended December 31, 2009, to reflect the removal of the pizza business operations from continuing operations.

(i) Cost of Sales

Cost of sales was reduced $968 million for the year ended December 31, 2009, to reflect the removal of the pizza business operations from continuing operations.

(j) Marketing, Administration and Research Costs

Marketing, administration and research costs were reduced $323 million for the year ended December 31, 2009, to reflect the removal of the pizza business operations from continuing operations.

(k) Indemnification Liabilities

Noncurrent liabilities have been increased $446 million and current liabilities have been decreased $262 million at December 31, 2009 to reflect a change in the anticipated timing of payment and amount of the estimated liability related to indemnifications granted to third parties.

(l) Pro Forma U.S. GAAP Adjustments

The following adjustments have been made to align the Cadbury IFRS financial information with Kraft Foods’ U.S. GAAP accounting policies.

Under IFRS, profit or loss arising on the sale and operating leaseback of property, plant and equipment may generally be recognized in the period in which the sale takes place. Under U.S. GAAP, a sale and leaseback of property, plant and equipment must first qualify for such accounting and then the profit or loss appraised is recognized depending upon the amount of use that the seller will retain of the property. Otherwise, the gain must be deferred and recognized over the lease period.

In 2006, Cadbury sold a property and leased it back resulting in the deferral of a gain under U.S. GAAP of $25 million which is recognized over the lease term. Marketing, administration and research costs were decreased $2 million for the year ended December 31, 2009, to recognize a portion of the gain. Other long term liabilities were not adjusted as the net impact of the adjustment for U.S. GAAP and the purchase accounting adjustment to fair value would have been zero.

Under IFRS, certain derivative instruments which qualified for hedge accounting had not met the requirements for hedge accounting under U.S. GAAP. Therefore, interest expense was increased by $5 million to adjust for the impact of the non-qualifying hedge.

Under IFRS, Cadbury recognized provisions of $36 million for future expected legal costs, for onerous supplier contracts and payroll related taxes. Under U.S. GAAP, these would not have met Kraft Foods’ criteria for recognition. Other current liabilities have been reduced by $10 million and noncurrent liabilities by $26 million for these provisions. Marketing, administration and research costs have been increased by $12 million for the year ended December 31, 2009 to recognize the periodic expense for these items.

Upon the adoption of IFRS, Cadbury elected to recognize all cumulative actuarial gains and losses at the date of transition. Under IFRS, all future actuarial gains and losses are also recognized in full outside the income statement in retained earnings and presented in a statement of recognized income and expense. U.S. GAAP does not permit recognition of all actuarial gains and losses in a separate statement other than the primary income statement.

For the year ended December 31, 2009, $95 million of Cost of sales and $95 million of Marketing, administration and research costs were recorded to recognize actuarial losses which were not recognized under IFRS. As of December 31, 2009, accrued pension liabilities were increased by $16 million due to a change in the actuarial value.

In order to recognize the tax benefit of a filing position, U.S. GAAP requires it be more likely than not to be sustained upon an audit. As this interpretation does not exist under IFRS, additional liabilities of $59 million related to uncertain tax positions were recorded as of December 31, 2009.

There was no net deferred tax impact related to these pro forma adjustments.

In the statement of operations, income tax expense was reduced by $62 million for the year ended December 31, 2009.

Also, under IFRS, Cadbury disclosed the deferred tax assets and liabilities as non-current. Under U.S. GAAP, deferred taxes are classified between current and non-current portion, depending on the items they relate to, disclosed separately and presented on a net basis, by tax jurisdiction. Note 3(m) further describes reclassification to reflect this difference.

(m) Reclassifications

Certain balances were reclassified from the financial statements of Cadbury so their presentation would be consistent with Kraft Foods.

The following reclassifications were made to the balance sheet as at December 31, 2009 (in millions):

The following reclassifications were made to the statement of operations for the year ended December 31, 2009 (in millions):

(n) Earnings per Common Share

Pro forma earnings per common share for the year ended December 31, 2009, have been calculated based on the estimated weighted average number of common shares outstanding on a pro forma basis, as described below. The pro forma weighted average number of common shares outstanding for the year ended December 31, 2009, has been calculated as if the acquisition shares had been issued and outstanding on January 1, 2009.

The following table sets forth the computation of basic and diluted earnings per share for the year ended December 31, 2009:
