October 2, 2017 AA+ (stable) "SEK's senior debt instruments continue to benefit from high government support given its strong linkages with the sovereign due to both its government ownership, as well as the special mandate the bank has to promote Swedish exports and manage the CIRR system."

SEK Green Bond Framework Second opinion “SEK bases its management of green projects on broad and well established guidelines like IFC’s Performance Standards on Environmental and Social Sustainability, IFC’s Environmental, Health and Safety General Guidelines and OECD’s “Common Approach” to environmental and social risks of projects. Furthermore, SEK employs the “International Financial Institution Framework for Harmonised Approach to Greenhouse Gas Accounting” for their CO2 impact assessment. Finally, SEK will establish a dedicated website which will allow for transparent reporting on all important aspects of the green bond program. Overall, we therefore find that SEK’s green bond framework has a very high probability of securing projects that support a low carbon and climate friendly future.” 17

SEK Green Bond Framework Use of Proceeds and Process for Project Evaluation and Selection • No fossil fuel projects are eligible. • The Eligible Projects are selected through the best of SEK’s capabilities, and are selected in two phases: 1.
