  • Represented clients before the Internal Revenue Service National Office and obtained, on behalf of such clients, favorable ruling on tax-free spinoffs under Section 355 of the Internal Revenue Code.
  • Advised numerous clients in workout and debt restructuring. From the debtor perspective, advised on how to minimize tax from the income recognized on the cancellation of indebtedness and how to preserve valuable net operating losses. From the creditor perspective, advised on how to maximize tax deductions associated with restructured debt.
  • Advised a waste disposal company in its tax-free acquisition of the outstanding stock of another company (valued at about $260 million). Acquirer had a preexisting stock ownership in Target which needed to be considered in choosing a viable acquisition structure. Moreover, Target had substantial net operating losses, which needed to be preserved for future use.
  • Advised a major manufacturing company in its tax-free acquisition of another manufacturing company (valued at $350 million). The tax structure of the transaction was complicated by the limitation on the amount of cash consideration that could be used by acquirer and by Target's planned sale of a division, constituting thirty percent of the value of its assets.
  • Advised three steel companies and their shareholders with respect to the tax-free acquisition of the companies by another steel company. the transaction was complicated in that it involved simultaneous mergers of the companies into acquirer.

  • Advised a chemical company on its tax-free acquisition of another corporation in which it owned a greater than twenty-percent interest.

Drafted ruling applications concerning the liquidation and the LLC formation. The IRS issued favorable rulings on both applications.
  • Advised a client on the tax consequences of its purchase of the stock of several subsidiaries of an unrelated corporation, including the advantages of a Section 338(h)(10) election.

  • Advised a domestic corporation on the sale of its indirectly owned foreign manufacturing subsidiary and that subsidiary's operating companies (valued at about $350 million). Numerous tax issues were considered, including whether a Section 338 election should be made and determining the Subpart F income and foreign tax credit consequences. Reduced by $80 million the overall gain on the sale of the subsidiary stock by restructuring the ownership of the subsidiary before negotiations for its sale occurred.
  • Advised domestic corporations (manufacturing and chemical concerns) on the tax consequences of their transfer of assets to foreign subsidiaries. This involved advising the client on the Section 367 aspects of the outbound transfers, as well as drafting gain recognition agreements.
  • Advised domestic corporations (manufacturing and food concerns) on the U.S. tax consequences of restructuring their foreign operations. This principally involved avoiding Subpart F income and, to the extent any such income resulted, maximizing the available foreign tax credits that could be used to reduce the overall tax cost of the restructuring. Saved one client $10 million in taxes by creatively using Section 304 rules.
  • Advised on the structuring of joint ventures entered into by domestic corporations and unrelated foreign corporations. This involved determining the most tax-favored structure (i.e., analyzing whether the joint venture entity would be a partnership or corporation) and ensuring that whichever structure was chosen would be respected for tax purposes. Also analyzed whether a corporation, if used, should be a CFC in order to maximize the domestic-parent corporation's foreign tax credit benefits. In addition, advised on the Section 367 consequences and exit strategies.
  • Advised a domestic corporation (a financial concern) on the tax consequences of converting its foreign subsidiary corporations into foreign partnerships.
