AND SUBSIDIARIES NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS Note 1 -- Basis of presentation: The unaudited pro forma condensed consolidated balance sheet reflects adjustments necessary to reflect (i) the distribution of a $200 million 9% promissory note payable by Kronos to NL and (ii) the distribution by NL to its shareholders of 23.9 million shares (48.8%) of the outstanding shares of common stock of Kronos, as if they had occurred on September 30, 2003. The unaudited pro forma condensed consolidated statements of operations reflect adjustments necessary to reflect such transactions as if they had occurred on January 1, 2002. At September 30, 2003, Valhi, Inc. and Tremont LLC, a wholly-owned subsidiary of Valhi, own an aggregate of approximately 85% of the outstanding shares of common stock of NL. Valhi, Tremont and NL are members of the same consolidated tax group for U.S. federal income tax purposes. NL is a party to a tax sharing agreement with Valhi pursuant to which NL generally computes its provision for income taxes on a separate-company basis, and NL makes payments to or receives payments from Valhi in amounts that it would have paid to or received from the U.S. Internal Revenue Service had NL not been a member of such consolidated tax group. Prior to completion of the distribution by NL to its shareholders of 48.8% of the outstanding shares of common stock of Kronos, Kronos and its qualifying subsidiaries were members of NL's tax group. Following completion of the distribution, Kronos and its qualifying subsidiaries will no longer be members of NL's tax group, but Kronos and its qualifying subsidiaries will remain members of the same tax group of which Valhi and Tremont are members. The distribution by NL to its shareholders of 48.8% of the outstanding shares of common stock of Kronos will be accounted for as a spin-off recorded at book value, net of tax. Such distribution is taxable to NL, and NL is required to recognize a taxable gain equal to the difference between the fair market value of the shares of Kronos common stock distributed ($17.25 per share, equal to the closing market price of Kronos' common stock on December 8, 2003, the date the distribution was actually completed) and NL's adjusted tax basis in such stock at the date of distribution. With respect to the shares of Kronos distributed to Valhi and Tremont (20.2 million shares in the aggregate), effective December 1, 2003, Valhi and NL have amended the terms of their tax sharing agreement to not require NL to pay up to Valhi the tax liability generated from the distribution of such Kronos shares to Valhi and Tremont, since the tax on that portion of the gain is deferred at the Valhi level due to Valhi, Tremont and NL being members of the same tax group. Therefore, NL will be required to recognize a tax on the distribution only with respect to the shares of Kronos distributed to NL shareholders other than Valhi and Tremont (3.7 million shares in the aggregate). Note 2 -- Unaudited pro forma condensed consolidated balance sheet - pro forma adjustments: The adjustment to minority interest as of September 30, 2003, represents recognition of the 48.8% of Kronos' pro forma net assets at such date which are attributable to Kronos shareholders other than NL. Such amount is calculated as follows: Amount (In millions) Kronos' historical net assets at September 30, 2003 $ 371.0 Less Kronos' promissory note payable to NL 200.0 ------- Kronos' pro forma net assets at September 30, 2003 $ 171.0 ======= 48.8% of Kronos' pro forma net assets $ 83.4 ======= The adjustment to payable to affiliates as of September 30, 2003 represents recognition of the income tax liability generated from the distribution of shares of Kronos common stock, as discussed above, and is calculated in the table below. Such tax liability has been calculated based on the actual closing market price for Kronos' common stock on December 8, 2003 (since there was no quoted market price for Kronos' common stock on September 30, 2003), and an estimate of the tax basis of the shares of Kronos common stock distributed as of September 30, 2003. NL's actual tax liability generated from the distribution will be based upon the tax basis of the shares of Kronos common stock as of the date of distribution (December 8, 2003). Amount (In millions, except per share amounts) Shares of Kronos common stock distributed to NL 3.7 shareholders other than Valhi and Tremont Multiplied by fair market value of the shares distributed at the time of the distribution $17.25 ------ Aggregated market value 63.9 Less aggregate tax basis in the shares distributed to NL shareholders other than Valhi and Tremont .4 ------- Taxable gain $ 63.5 ======= Tax on taxable gain at estimated combined U.S. federal and state effective tax rate of 38.3% $ 24.3 ======= The adjustment to retained earnings represents the book value, net of tax, of the shares of Kronos common stock distributed. There is no recognition in NL's unaudited condensed consolidated balance sheet of Kronos' $200 million promissory note payable to NL as such note payable is eliminated in NL's consolidated financial statements. Note 3 -- Unaudited pro forma condensed consolidated statements of income - pro forma adjustments: The adjustment to minority interest for the year ended December 31, 2002 and the nine months ended September 30, 2003 represents recognition of the 48.8% of Kronos' pro forma net income for such periods which are attributable to Kronos shareholders other than NL. Such amounts are calculated as follows: Year ended Nine months ended December 31, 2002 September 30, 2003 (In millions) Kronos' historical net income $ 66.3 $ 74.4 ---------- --------- Less net-of-tax interest expense on Kronos' $200 million 9% promissory note payable to NL: Interest expense at 9% 18.0 13.5 Tax benefit at estimated combined U.S. federal and state effective tax rate of 38.3% 6.9 5.2 ---------- --------- 11.1 8.3 ---------- --------- Kronos' pro forma net income $ 55.2 $ 66.1 ========== ========= 48.8% of Kronos' pro forma net income $ 26.9 $ 32.2 ========== ========= NL provides incremental income taxes on its equity in the net income of domestic subsidiaries and affiliates that are not members of NL's tax group. The adjustment to the provision for income taxes (benefit) for the year ended December 31, 2002 and the nine months ended September 30, 2003 represents recognition of such incremental income taxes on the 51.2% of Kronos' pro forma net income which are attributable to NL, using the 7% dividends received deduction effective income tax rate. There is no recognition in NL's unaudited pro forma condensed consolidated statements of income for interest expense associated with Kronos' $200 million promissory note payable to NL as such interest expense is eliminated in NL's consolidated financial statements. Note 4 -- Pro forma per share amounts: The pro forma basic and diluted earnings per share amounts are based upon NL's historical basic and diluted weighted average shares outstanding for the year ended December 31, 2002 and the nine months ended September 30, 2003.
