For January-December 2015, the operating cash flow totalled EUR 255 million (452). Working capital totalled EUR 543 million (251) at the end of the financial period. The increase was mainly due to the Energy Solutions business, where the timing of deliveries resulted in inventory build-up and increased receivables. Furthermore, advances received at the end of the period declined to EUR 564 million (673) due to lower order intake in the equipment businesses. Cash and cash equivalents at the end of the period amounted to EUR 334 million (571) and unutilised Committed Credit Facilities totalled EUR 679 million (629).
Wärtsilä had interest-bearing debt totalling EUR 724 million (666) at the end of December 2015. The total amount of short-term debt maturing within the next 12 months was EUR 232 million. Long-term loans amounted to EUR 492 million. Net interest-bearing debt totalled EUR 372 million (94) and gearing was 0.17 (0.05). The increase in gearing relates mainly to working capital build up and the acquisition of L-3 Marine Systems International.
