Noora Ahonen

Senior Associate, Member of the Finnish Bar, M.Sc. (Econ.)

I advise our clients on a wide array of domestic and international tax matters. I joined Castrén & Snellman in 2021. Before joining Castrén & Snellman, I worked, among other things, as a tax specialist in the Finnish Tax Administration, as a judge of the administrative court, as tax consultant for a major auditing firm and as a lawyer at another Finnish law firm. I have, therefore, worked with a wide range of tax matters concerning both private persons as well as domestic and international organisations and gained valuable experience in handling tax matters in the Finnish Tax Administration and in the administrative courts.

In addition to my law degree, I hold a Master of Science in Economics. I have also completed court training, i.e. I have appointed as a lawyer trained on the bench.

We advised Jefferies as the sole arranger and lead manager in a transaction in which Finnfund, a Finnish development financier and impact investor, issued a EUR 100 million green bond. The 10-year bond bears interest at the rate of 3.5% per annum. The bond offering was placed to international investors, including a portion of dedicated green bond investors/portfolios. The bond represents Finnfund’s first ever green transaction and second issuance under its Sustainability Bond Framework established in September 2022. The proceeds from the issue will be used in accordance with the green project categories of Finnfund’s Sustainability Bond Framework to finance and/or refinance eligible green lending, equity investments, and mezzanine financing mainly targeting, for example, the objective of climate change mitigation and adaptation and/or environmentally sustainable management of living natural resources. Net proceeds will be allocated to eligible projects with the objective to mobilise debt capital to support Finnfund’s mission to generate lasting impact by investing in businesses that solve global development challenges. In addition, it contributes to Finnfund’s goal to foster sustainable development by providing investment opportunities for private investors. In its strategy, adopted in January 2022, Finnfund sets one of its targets to fund 50% of its investments with private capital by 2030. Mobilising private capital is key to achieving the UN Sustainable Development Goals (SDGs) in developing countries, given that the UN estimates the financing gap at USD 2.5 trillion per year. Jaakko Kangasniemi, Managing Director, CEO at Finnfund said: “Sustainable, innovative businesses and investors play an integral role in solving both global and local challenges, such as climate change mitigation and adaptation, and biodiversity loss. Capital markets are also vital in the transition away from fossil fuels. We are glad to have such a strong support for our impact investing activity and our mission to foster sustainable development and green transition.” Andrey Medvedev, Senior Vice President at Jefferies said: “We are delighted to have assisted Finnfund issuing its longest private placement to date and showcasing its innovative green projects. This deal demonstrates Finnfund’s appeal to a diversified international investor base and cements its position as a leading development financing agency.”

Life Finland Oy, a retailer of natural products, other health-related products and cosmetics, filed for bankruptcy on its own initiative in June 2025, and our attorney, counsel Elina Pesonen was appointed administrator of the bankruptcy estate. Life Finland Oy was part of the international Life Group, and its parent company Life Europe AB was declared bankrupt in Sweden in June 2025. When declared bankrupt, Life Finland Oy had over 30 operational stores and almost 170 employees across Finland. In addition to the premises of the operational stores, the company had several other leased premises, such as retail premises it was vacating as well as office and warehouse spaces. The bankruptcy estate organised clearance sales in all of the company’s stores. The shutdown of the stores and the clearance sales were efficiently carried out in approximately two weeks in cooperation with the company’s country manager, regional managers and sales staff. The clearance sales yielded a significant liquidation result, and consumers bought nearly the entire inventory. The administration of the bankruptcy estate has required expertise in many areas. The proceedings have dealt with specialised issues such as cash pooling arrangements, intellectual property, franchising agreements, employment relationships and consumer creditors. In addition, the proceedings are notably international, as the estate administrator has organised the shutdown of operations and the liquidation of assets in close cooperation with the estate administrators of the Swedish Group companies. The cooperation has included, among other things, exploring opportunities for selling the business, the sale of intangible rights and the coordination of intra-group agreements.
