International reinsurance companies – Ad hoc arbitration proceedings
We successfully represented a panel of reinsurance companies in an international ad hoc arbitration. The dispute arose out of a reinsurance treaty under the terms of which the reinsurers had reinsured a portfolio of risks underwritten by the cedent. The parties disagreed as to whether the reinsurance provided coverage for a certain loss that had occurred because of the market turmoil caused by the Covid-19 pandemic. The case involved highly complex legal and contractual questions requiring special expertise on reinsurance law and practice. The arbitral tribunal rejected the counterparty’s claims for reinsurance compensation against our clients in full. The amount in dispute was approximately EUR 34 million.

Valio and C&S – Sustainable everyday life is created through bold reforms
Valio is a food company with the courage to change with the times. Valio’s road to growth and towards the innovative transformation of the food industry is supported by its long-standing business law partner, Castrén & Snellman. Juha Hölttä became Valio’s General Counsel at a time when the company kicked its new strategy into a higher gear. ‘In the past two years we have made several significant market initiatives and expanded our business from food production to other areas of the value chain. By acquiring Heinon Tukku, we now provide a new kind of added value to restaurants and professional kitchens through our Valio Aimo ® wholesale business. And our joint venture with St1, Suomen Lantakaasu Oy, will enable us to reach our goal of turning manure into biogas for heavy transportation,’ Hölttä describes some of the milestones of the new strategy. In addition to expanding into new business areas, Valio continues to build a more sustainable dairy business alongside seeking international growth from plant-based products. Valio has invested in the international growth of its Oddlygood ® brand through incorporation and gained additional product development expertise through the acquisition of Gold&Green. Carbon footprint of milk reduced by new business operations Dairy products are at the core of Valio’s business, and the company develops this strong foundation not only through product innovation but also at the beginning of the food chain. ‘Who could have foreseen that dairy farm manure could become one way of tackling climate challenges? Our planned biogas plants will use manure and agricultural by-products to produce renewable liquefied biogas for use as transportation fuel,’ says Hölttä. ‘Valio is aiming for a carbon-neutral milk chain by 2035. We are making major reforms in our operations in order to make this happen.’ The sustainability programme for Valio’s 3,700 dairy farms has been expanded, and it now includes the preventive and systematic healthcare of cows as well as actions related to grazing, the climate and biodiversity. ‘Appreciation for locally produced food is on the rise, which means that sustainability questions are local as well. This is a good trend, as it makes it easier for us to make a difference.’ ‘Strategic help even in difficult circumstances’ The service-mindedness of lawyers is key in implementing a growth strategy. Castrén & Snellman Attorneys is a long-standing partner of Valio, and the relationship between the two is tight. ‘At Valio, we are always exploring new business opportunities, and us lawyers are tasked with assessing these opportunities. My philosophy as the General Counsel is that my door is always open. Together we can evaluate how to solve and implement new initiatives. In this job, you must be curious, broad-minded and business-oriented,’ summarises Hölttä. Hölttä’s legal team of five people is supported by experts from Castrén & Snellman. The key to successful partnership is that both parties are familiar with each other’s business operations and ways of working. ‘Castrén & Snellman knows us well, and they maintain an up-to-date overview of our situation, which I highly appreciate. It means that we are able to tackle tricky situations together quickly even in difficult circumstances.’ A joint fast reaction was needed, for example, when Valio exited the Russian market after the country launched its war of aggression on Ukraine. ‘The responsible thing was to leave quickly but in a controlled manner and by repatriating our investment as opposed to leaving an operational food production facility in the hands of a country that was waging war.’ A shared vision of sustainability Valio – Together we make life better A Finnish food company Approx. 4,600 employees Owned by 13 Finnish dairy cooperatives Finland’s most sustainable brand in the Sustainable Brand Index study Read more about sustainability at Valio Castrén & Snellman – Building sustainable success stories Forerunner of demanding legal services 300 employees Owned by its partners ‘We help our clients build sustainable success stories and achieve their sustainability goals.’ Read more about sustainability at Castrén & Snellman Shared success stories of Valio and C&S Global Brand Portfolio Management and IP Enforcement Purchase of Gold&Green’s Brand, IPR and R&D Function Joint Venture for Biogas Production with St1 Sale of Russian Operations Acquisition of Heinon Tukku Significant Growth Funding Round Competition Damages Case Defending Against Environmental Permit Challenge at the Appellate Level

Gasum and C&S – A Shared Course to a Cleaner Future
Over the past seven years, Gasum has transformed itself from a traditional Finnish gas distributor to a modern energy company and significant circular economy operator in the Nordic countries. Castrén & Snellman has stood by Gasum’s side throughout this journey.  When General Counsel Tiia Ryhänen joined Gasum in 2013, the company was still a traditional gas distributor. ‘We closed our first liquefied natural gas (LNG) acquisition in 2014. In the seven years since, Gasum has transformed itself into a modern, international energy company and circular economy operator’, Ryhänen said. This major shift has taken place through a series of corporate transactions. Ryhänen has been involved in every one of them over the past seven years. ‘It has been exciting to be a part of creating something new and expanding the company. I have particularly enjoyed welcoming many new people onto the Gasum team.’ ‘Like an Extension of Our In-House Team’ Castrén & Snellman Attorneys has been Gasum’s partner from the very start. ‘C&S has stood by our side throughout this journey. We have a strong partnership. C&S really understands how we handle acquisitions. We always want to act in a way that respects the people on the other side of the table’, Ryhänen said. Ryhänen’s team includes three other in-house lawyers. Since last August, the team has also had one of Castrén & Snellman’s lawyers ‘on loan’, i.e. on secondment. ‘C&S is like an extension of our in-house team. We work with at least one of their lawyers nearly every week. We regularly talk about the best ways to move forward in assignments. We can trust them to always deliver on their promises.’ Towards a Carbon-Neutral Society Gasum is a Nordic gas sector and energy market expert. The company’s strategy is to expand the natural gas market. Our work has a shared purpose: cleaner energy. ‘The demand for natural gas and biogas is growing fast, because fighting climate change requires switching to cleaner solutions. We are building a bridge towards a carbon-neutral society together with our customers and partners.’ In practice, this goal means that Gasum will have to expand its network of gas filling stations, increase its production and sourcing of biogas and help its customers reduce their emissions. ‘We have also expanded our operations on the electricity market. Last September, we entered into a long-term wind power deal with ABO Wind Oy for the output of their wind park. In 2023, we will begin selling our customers renewable wind power produced in Kestilä.’ Gasum’s Journey to a Modern Circular Economy Operator with C&S 2020 Gasum acquires the entire share capital in Swedish biogas producer Skövde Biogas AB from Torran Gas Holding AB. 2019 Gasum acquires AGA’s Clean Energy business and Nauticor’s Marine Bunkering business from Linde AG. Gasum sells its subsidiary Gasum Tekniikka Oy to industrial maintenance partner Viafin Service Oyj. 2018 Gasum increases its shareholding in Skangas to 100%. Gasum acquires Enegia Group Oy’s energy market services business. 2017 Gasum increases its shareholding in Skangas to 70%. Gasum sells its heat business and natural gas retail business to Auris Kaasunjakelu Oy in the Auris gas distribution network area. Gasum acquires 100% of the shares in the Swedish biogas producer Swedish Biogas International. The acquisition makes Gasum the leading producer of biogas in the Nordic countries. 2016 Gasum acquires the Biotehdas biogas plant chain owned by Taaleritehdas Biofactory I Ky Private Equity Fund. Gasum and its subsidiary Skangas acquire the Risavika LNG production plant in Norway from Lyse Group. Gasum acquires the full shareholding of Biovakka Oy. 2015 Gasum sells the shares in its subsidiaries Gasum Paikallisjakelu Oy and Helsingin Kaupunkikaasu Oy to SL Capital Partners. 2014 Gasum acquires a majority in Skangass’s liquefied natural gas (LNG) distribution operations from Lyse Corporation. The acquisition makes Gasum the leading Nordic LNG operator.
