Alitalia board votes to accept Etihad offer, rapidly do deal- CEO

ROME (Reuters) - The board of Italy's troubled airline Alitalia on Friday voted to accept an offer by Etihad Airways to invest in the company, and said it would move quickly to conclude the tie-up, the company's chief executive said.

"Today the Etihad plan was approved, and the board delegated myself and the chairman to study and rapidly come up with a draft of the final contract," Alitalia CEO Gabriele Del Torchio said.

Abu Dhabi-based Etihad is prepared to invest up to 1.25 billion euros (1 billion pounds) over the next four years, Italy's transport minister said on Wednesday.

Italy's flagship carrier Alitalia, which received a 500 million-euro government-engineered rescue package last year, risks running out of cash by August unless it can find a cash-rich partner.

In a statement the privately held airline said it approved its 2013 balance sheet, without giving details. It said only that it wrote down 233 million euros in charges and devaluations for 2013 "in preparation for future strategies".

A source with knowledge of the company's 2013 balance sheet said losses, excluding the write-down, amounted to about 290 million euros.

Alitalia is still negotiating with banks about restructuring about 700 million euros in debt, Del Torchio also said.

"We're proceeding, but you must understand that the sums are not small. We're still working on it," he said.
