Finnish Centre for Pensions – Information design workshop

We delivered two information design workshops for the legal department of the Finnish Centre for Pensions, with participants from both legal and other professional backgrounds. In the sessions, we applied the principles of legal design thinking to the Finnish Centre for Pensions’ field of operation and background materials, also utilising AI as a design tool. The participants found the tailored training highly useful and commended the trainers for their in-depth familiarisation with the Centre’s opinion drafting process and operating environment. As a result of the workshops, our experts proposed a new structural and linguistic model for the legal department of the Finnish Centre for Pensions for drafting opinions and guidelines. The proposal was well received as clear and applicable to the participants’ everyday work. In addition, we presented tailored AI use cases to support experts, allowing for a more efficient AI-assisted way of working. Our experts who delivered the workshops combined their legal expertise with their leading experience in legal design. The participants appreciated this versatile expertise, which enabled a knowledgeable, creative and applied approach to legal writing. ‘C&S created a well-structured training tailored to our needs, providing clear direction for our organisation and concrete takeaways for our experts in their day-to-day work,’ says Mari Kuunvalo, Head Of the Legal Department at the Finnish Centre for Pensions.

SATO – Legal design of Code of Ethics

We drafted new Codes of Ethics for SATO to use internally and with business partners. The client wanted to get concise and legally up-to-date Codes that are easy to understand and look fresh. We drafted completely new Codes, designed a clear structure for them and designed and implemented their layout. We made separate Codes of Ethics for internal use and for business partners in order to meet the exact tone and style suitable for both end user groups. We also made English translations of the Codes of Ethics. The end product was practical and interactive PDF instructions that are consistent with the client’s visual style. Client insight and taking the target group’s needs into account are some of the main principles of legal design. The client’s wishes also focused on the end users of the Code of Ethics, i.e. the company’s employees and business partners. In this project, efficient project management and an open line of communication helped us understand the wishes of the client company and deliver an end product with which the client was very happy. Active dialogue with the client was an important quality factor in this agile and iterative project. In the first phase we provided the client with a prototype and then continued the design work based on the comments we received. The appearance of the final product was designed in accordance with the client’s graphical guidelines. SATO Corporation is an expert in sustainable rental housing and one of Finland’s largest rental housing providers. SATO owns around 25,000 rental homes in the Helsinki Metropolitan Area, Tampere and Turku. Approximately 45,000 residents live in SATOhomes. The project involved experts in legal design, linguistics and graphic design, and members of our Legal Tech team.

Aktia Bank – EUR 80 million AT1 bond

We advised Aktia Bank Plc on the issuance of an EUR 80 million Additional Tier 1 (AT1) bond. The bond pays a fixed interest rate of 6.75 per cent semi-annually. The bond is perpetual, and Aktia has the right to redeem or repurchase it in accordance with the terms of the bond, subject to certain conditions. The bond was issued on 1 April 2026. In addition, we assisted Aktia in listing the bond on the Nasdaq Helsinki Ltd stock exchange. For the listing, we prepared Finland’s first EU Follow-on prospectus for a bond. The EU Follow-on prospectus was introduced on 5 March 2026 with an update to the Prospectus Regulation (EU) No. 2017/1129. The EU Follow-on prospectus is a new type of prospectus that can be used, among others, by issuers whose securities have been admitted to trading on a regulated market continuously for at least the 18 months preceding the offer to the public or the admission to trading on a regulated market of the new securities. A follow-on prospectus is simpler than a so-called traditional prospectus, and it is intended to avoid repeating information that the issuer has already disclosed. Nordea Bank Abp acts as the sole structuring advisor for the issue of the Notes. Nordea Bank Abp, Danske Bank A/S and ABN Amro Bank N.V. act as the lead managers for the issue of the Notes.

Aurevia and Labquality – Strategic reorganisation

We advised Aurevia Oy, a portfolio company of French private equity sponsor Mérieux Equity Partners, in a strategic reorganisation that involved splitting Aurevia and its parent companies into two independent groups of companies and reorganisation of its existing debt-financing arrangements. Following the reorganisation, the newly formed Aurevia continues as a leading provider of Contract Research Organization (CRO) and Quality Assurance and Regulatory Affairs (QARA) services, while the newly formed Labquality focuses on delivering External Quality Assessment (EQA) services. Aurevia serves operators in the medical devices, in vitro diagnostics and pharmaceutical sectors. Labquality’s customers include clinical laboratories and social and healthcare organisations. The reorganisation positions Aurevia and Labquality to allocate investments more effectively, accelerate growth within their respective customer segments, and respond to evolving market and client needs. The transaction was implemented through multiple parallel demergers and required comprehensive legal and tax structuring across several jurisdictions. Our team supported Aurevia throughout the planning and implementation phases, covering corporate, tax, employment law, and regulatory matters, as well as the optimisation of each group’s financing structure.
