Demag Cranes AG recognises – primarily in Germany – liabilities for amounts payable and top-up amounts under existing partial retirement plans and for expected top-up amounts under partial retirement plans whose signing is probable as of the balance sheet date. The amount of the obligation under partial retirement plans is measured in accordance with actuarial principles. The obligation incorporates the full amount of increases under signed partial retirement plans. A pro rata amount is recognised for wages and salaries that continue to be payable during the non-working phase of partial retirement corresponding to service rendered during the working phase. Top-up amounts for impending additional plans are included in the liability in the expected amount of vested benefits to be claimed. Factors taken into account in measurement of the obligation include the end of legislative provision for partial retirement plans and the maximum levels of benefit payable to employees in partial retirement under the law and collective agreements.
