3. -- Ford (F)  aims to cut about 10% of its global workforce amid CEO Mark Fields's drive to boost profits and the automaker's sliding stock price, The Wall Street Journal reported, citing people briefed on the plan.

The job cuts could be announced this week, the Journal reported.

The job cuts largely target salaried employees. It's unclear if the plan includes cuts to the hourly workforce at Ford's U.S. factories and plants that are abroad, according to the Journal. Ford has about 200,000 employees worldwide.

Ford's board last week extended its scheduled meetings to press Fields to clarify his strategy as the company's stock price languishes and its U.S. market share recedes, sources told the Journal.

While Ford has been profitable since Fields became CEO in July 2014, shares have fallen by about a third over that period.
 
Ford shares were rising 0.9% in premarket trading on Tuesday. For the year so far, the stock has fallen 9.8%.

5. -- Walt Disney (DIS) CEO Bob Iger said hackers are claiming to have access to an unreleased Disney movie and are demanding a ransom, according to the Hollywood Reporter.

Iger didn't provide the name of the film. He said Disney was refusing to pay the hacker's ransom and was working with federal investigators. Iger said the hackers have demanded a substantial ransom be paid via Bitcoin. 

Iger's comments came during a town hall meeting with ABC employees in New York, according to the report.

The hackers have threatened to release five minutes of the film the first time and then in 20-minute chunks until their financial demands are met.

Iger's comments come in the aftermath of the "WannaCry" global ransomware attack that was estimated to have affected more than 200,000 computers in 150 countries since its initial launch last Friday.
