Pursuant to Section 341r No. 1 of the German Commercial Code, activities in the extractive industry comprise activities in the field of exploration, prospection, discovery, development and extraction of minerals, oil and natural gas deposits or other substances in the sectors listed in Annex I Paragraph B Sections 05 to 08 of Directive (EC) No. 1893/2006 of the European Parliament and of the Council of December 20, 2006 establishing the statistical classification of economic activities NACE Revision 2 and amending the Council Regulation (EEC) No. 3037/90 and certain EC regulations on specific statistical domains (OJ L 393 of December 30, 2006, p. 1).

Payments are all amounts paid as a benefit in kind or cash benefit in connection with activities in the extractive industry when they are conducted pursuant to Section 341r No. 3 of the German Commercial Code for one of the reasons listed below:

1. Production entitlements,

2. Taxes levied on the income, output or profits of corporations and excluding excise taxes, sales taxes, value added taxes as well as taxes due on the wages/salaries of persons employed by corporations and similar taxes,

3. Usage fees,

4. Dividends and other profit distributions arising from shareholdings,

5. Signature, discovery and production bonuses,

6. License, lease and access fees as well as other considerations for licenses or concessions and

7. Payments for infrastructure improvements.

Pursuant to Section 341r No. 4 of the German Commercial Code, government entities are national, regional or local authorities of a Member State of the European Union, another signatory state of the Treaty on the European Economic Area or a third country including the departments or agencies controlled by an authority and companies that can exert a dominant influence on one of these authorities within the definition of Section 290 of the German Commercial Code.

Pursuant to Section 341r No. 5 of the German Commercial Code, projects are the totality of operational activities that form the basis for payment obligations toward a government entity and are based on

+ a contract, a license, a lease, a concession or a similar legal agreement or

+ a totality of operationally and geographically related contracts, licenses, leases or concessions or related agreements with a government entity, which essentially establish similar conditions.

The Group Payment Report includes payments that result from activities within the framework of the extraction and development of raw materials or related upstream activities, for example from exploration, prospection or discovery, and which can be assigned to the types of payments mentioned before. Payments to government entities which are not directly related to activities in the extractive industry are outside the scope of application and thus are not to be included in the Group Payment Report.

The reported payments reflect the actual payment outflows of the companies included in the Group Payment Report in the year under review.

Repayments by a government entity reduce the amount of payments to be reported provided that the payment and corresponding repayment occur within the same period under review and arise from the same matter. Repayments resulting from payments in previous years are not taken into consideration.

If a payment is made in connection with activities related to the extractive industry as well as with other activities, the main purpose of the payment is the determining factor. A payment is included in the Group Payment Report if the main purpose of the payment results from activities related to the extractive industry. There is no artificial division of the payment into a part that is subject to the disclosure obligation and one that is not.

Payments that cannot be assigned exclusively to one project are disclosed as "non-project-related payments". At the K+S Group projects are equated with plants.

The K+S Group did not make any payments in kind to government entities for activities in the extractive industry in the period under review.

Payments made in foreign currencies (not €) were converted with the exchange rate on the date of payment (= Transaction rate).

For reasons of materiality, government entities to which a total of less than € 100,000 have been paid in the period under review can be excluded from the Group Payment Report. This materiality threshold is applied.

Payments that are voluntarily included in the Group Payment Report are explicitly marked. These payments are stated aggregated at country level. There is no differentiation by government entity, divided by projects.

The following overview A.1 shows the payments made to government entities in the reporting year by the K+S Group broken down by country and payment type. The respective beneficiary government entities can be found in the country overviews A.2 - A.4.

1 Pursuant to Section 341r No. 3 b) of the German Commercial Code.

2 Pursuant to Section 341r No. 3 c) of the German Commercial Code.

3 Pursuant to Section 341r No. 3 f) of the German Commercial Code.

* K+S Aktiengesellschaft and the vast majority of its domestic subsidiaries form a single unit for trade tax and corporate tax purposes. As the taxpayer, K+S Aktiengesellschaft makes regular payments for these controlled companies ("tax group"). A part of these payments can be attributed to activities in the extractive industry and are thus subject to disclosure. An analysis of the main purpose of the payments made has demonstrated that the overwhelming majority of the payments made by the taxpayer do not result from activities in the extractive industry, but from the production and distribution of fertilizers and products for industrial applications, as well as the disposal activities for the subterranean disposal and recovery of waste and other services. Consequently, they are outside the scope of application and are not included in the table above. However, the payments made by K+S Aktiengesellschaft are disclosed voluntarily hereinafter at the accumulated level:

In the year under review K+S Aktiengesellschaft paid income taxes in the amount of € 11,371,287 of which € 6,422,723 was for corporate tax and € 4,948,564 for trade tax.

The country overviews show the payments made to government entities in the reporting year broken down by project and payment type.
