Notable Representations

Estate Planning for Business Owner (IDGT, GST) To minimize the impact of taxes on the transfer of wealth from generation to generation, Ann guided a successful business owner in selling his company interests to carefully structured, irrevocable trusts established for the benefit of his children. The design of the plan enabled the client to maintain cash flow from installment payments made under the sale agreement, while avoiding the payment of capital gains tax. Following conclusion of the transaction, the entire business value was excluded from the client’s taxable estate resulting in significant tax savings.

Merger of Tax Exempt Organizations Ann facilitated the merger of two long-term, successful social service agencies. Through her representation, a local pregnancy support agency was able to combine forces with a complimentary social service organization to create a single entity able to provide higher quality service than either agency could accomplish individually. The newly structured continuing organization is now able to provide a seamless continuum of service to persons who otherwise lack financial, health and social supports.

Conversion of Non-Profit Entity Ann represents a tax exempt organization created upon the conversion of an insurer from nonprofit status to for-profit ownership. Past efforts have included liquidation of significant stock holdings, negotiation of applicable grant agreements, assistance with regulatory matters and general corporate law assistance. Since its creation, the organization has made significant distributions in support of Wisconsin public health initiatives.
