1.A person who receives a pension or pensions under the legislation of one or more Member States and who is not entitled to benefits in kind under the legislation of the Member State of residence shall nevertheless receive such benefits for himself and the members of his family, insofar as he would be entitled thereto under the legislation of the Member State or of at least one of the Member States competent in respect of his pensions, if he resided in that Member State. The benefits in kind shall be provided at the expense of the institution referred to in paragraph 2 by the institution of the place of residence, as though the person concerned were entitled to a pension and benefits in kind under the legislation of that Member State.
2.In the cases covered by paragraph 1, the cost of benefits in kind shall be borne by the institution as determined in accordance with the following rules:
(a)where the pensioner is entitled to benefits in kind under the legislation of a single Member State, the cost shall be borne by the competent institution of that Member State;
(b)where the pensioner is entitled to benefits in kind under the legislation of two or more Member States, the cost thereof shall be borne by the competent institution of the Member State to whose legislation the person has been subject for the longest period of time; should the application of this rule result in several institutions being responsible for the cost of benefits, the cost shall be borne by the institution applying the legislation to which the pensioner was last subject.
