Greek operator Wind Hellas said it began talks with creditors because of a slump in sales and earnings in April and May caused by the government’s austerity measures, reports Bloomberg. Sales in the two months dropped 27 percent from the same period a year earlier to EUR134 million, while EBITDA and some items fell 54 percent to EUR25.2 million, according to a presentation on the company’s website. The launch of the Greek government’s austerity measures in April has further impacted performance, and is putting significant additional pressure on Wind Hellas’ capital structure, the company said.
