For the purposes of this letter we have, except as set out herein, made no examination of the files or records of any company or any governmental or regulatory agency or authority or any other entity or person nor have we examined any other documents or instrument than those explicitly set out herein.

Based on the foregoing, it is our opinion that under Swedish law as in force at the date hereof:

1.                             The Company is a limited liability company duly organised and validly existing under the laws of Sweden and, based on a telephone enquiry with the District Court of Stockholm (Sw. Stockholms tingsrätt) and a search at the Swedish Companies Registration Office, which enquiry and search are not conclusive, the Company is not in liquidation (Sw. likvidation) or bankruptcy (Sw. konkurs) and to the best of our knowledge (without having made any specific enquiry save for the search at the Swedish Companies Registration Office) no steps have been taken or are being taken to wind up (Sw. likvidera) the Company.

2.                             Each of (i) the 1991 Indenture; (ii) the First Supplemental Indenture; (iii) the Second Supplemental Indenture; (iv) the Third Supplemental Indenture; (v) the Fourth Supplemental Indenture; (vi) the Fifth Supplemental Indenture, and (vii) the Sixth Supplemental Indenture has been duly authorised and executed by the Company, and each of the 1991 Indenture; the First Supplemental Indenture; the Second Supplemental Indenture; the Third Supplemental Indenture; the Fourth Supplemental Indenture; the Fifth Supplemental Indenture, and the Sixth Supplemental Indenture is a valid and legally binding instrument of the Company enforceable in accordance with its terms under the laws of Sweden.

3.                             The issuance and execution by the Company of the Notes have been duly authorised by all necessary corporate action of the Company; the Notes have been duly executed by the Company under the laws of Sweden, and the Notes constitute valid and legally binding unsecured general obligations of the Company enforceable in accordance with their terms under the laws of Sweden and are entitled to the benefit of the Indenture.

4.                             The Company possesses the corporate power to issue the Notes and to perform its obligations under the Indenture.

In rendering the foregoing opinions, we have relied as to certain factual matters upon certificates and statements of officers of the Company and of public officials and we have further assumed the genuineness of all signatures on all documents and the completeness and conformity to original documents of all copies submitted to us and that any resolutions passed at any meetings of the Board of Directors of the Company, and all other authorisations, powers and authorities produced to us, remain in full force and effect and have not been revoked, superseded or varied. Nothing in this opinion must be taken as indicating that the obligations discussed herein would be enforceable prior to other unsecured general obligations of the Company.

Page 3 (5)

We express no opinion whatsoever as to the laws of any jurisdiction other than Sweden and have assumed that there is no provision of any law of any jurisdiction (other than Sweden) which would have any implication on the opinions expressed above. Further, we have assumed that any document or obligation governed by laws other than those of Sweden is (or, in respect of documents or obligations governed in part by laws other than those of Sweden and in part by the laws of Sweden, such as the Indenture, the portions thereof that are governed by laws other than those of Sweden are) under such laws legal, valid, binding and enforceable and that all documents have been duly authorised and duly executed by all parties thereto (other than the Company).

The opinions expressed above are subject to the qualification that the enforcement of any agreement, guarantee or instrument may be limited by bankruptcy, insolvency, liquidation, reorganisation, resolution, limitation, moratorium, stay and other laws of general application regarding or affecting the rights of creditors generally and general equitable principles. Without limiting the generality of the foregoing, the enforcement of any agreement, guarantee or instrument may be limited or affected by the application of Directive 2014/59/EU of the European Parliament and of the Council of 15 May 2014 (as amended, supplemented or replaced, including without limitation by Directive (EU) 2019/879), establishing a framework for the recovery and resolution of credit institutions and investment firms as implemented in Sweden pursuant to inter alia the Swedish Resolution Act (Sw. lag (2015:1016) om resolution) (together, the "BRRD Legislation"), including but not limited to in respect of debt write-down tools within the BRRD Legislation pursuant to which claims under the Notes, if the Company in the future again were to be assessed to be subject to being managed through resolution, may be written down, converted or stayed (or the maturity, interest rate or interest payment date for the Notes may be amended or changed).

This opinion is rendered in Sweden and shall be governed by and construed in accordance with Swedish law.

We hereby consent to the filing of this opinion as Exhibit 5(a) to the Company’s Report on Form 6-K dated 2 July 2025, without thereby admitting that we come within the category of persons whose consent is required under Section 7 of the United States Securities Act of 1933, as amended (the “Securities Act”), or the rules and regulations of the Commission issued thereunder, nor that we are “experts” under the Securities Act, or the rules and regulations of the Commission issued thereunder, with respect to any part of the Registration Statement, including this exhibit.

The opinions expressed herein are rendered on and as of the date hereof, and we assume no obligation to advise you or any other person, or to make any investigations, as to any legal developments or factual matters arising subsequent to the date hereof that might affect the opinions expressed herein.

Very truly yours,
