Monday is the final trading day of the first half of 2014 and it's shaping up to be quite eventful.

Here are the six things you need to know before the opening bell rings in New York:

1. Record fine for BNP Paribas?: The U.S. Department of Justice is expected to announce a multi-billion dollar settlement with French banking giant BNP Paribas (BNPQY) on Monday. The bank has been subject to a long running criminal investigation over accusations that it breached U.S. sanctions on Iran, Sudan and other countries. Shares in BNP dipped in Paris by 0.5%.

2. GM details compensation: Kenneth Feinberg, a consultant who worked on payouts after the 9/11 terrorist attacks and the BP oil spill, will announce a victim compensation plan for General Motors (GM) at 10 a.m. ET. At least 13 people have died and many more were injured as a result of a defect in GM cars.

3. Will Facebook fury hit stock?: Facebook (FB) is in hot water after people learned the company conducted a 'mood' experiment on users without their knowledge or explicit consent. The study found that users who were shown more negative content in their News Feeds were slightly more likely to produce negative posts. Facebook's terms of service give the company permission to conduct this kind of research, but many users have reacted with anger. Facebook shares were down slightly ahead of the open.

4. Premarket moves: U.S. stock futures were calm ahead of the trading day. Trading was mixed. The main stock making waves was Yahoo. (YHOO) Shares in the online service were rising by 2%. The company owns a large stake in the highly successful Chinese e-retailer Alibaba, which is preparing to go public.

5. Market recap: U.S. stocks ended last week on a positive note. However, the S&P 500 and Dow Jones Industrial Average ended the week down overall.

Tech stocks had a strong week, with GoPro (GPRO)'s IPO creating buzz in the markets.

6. International markets mostly positive: European markets were mixed in midday trading. Asian markets ended mixed. The main loser of the day was Australia's ASX All Ordinaries index, which dropped by 0.9%.

It's also worth keeping an eye on Argentina's markets. The country faces a Monday deadline to pay two groups of bondholders. The way things unfold from here will determine Argentina's ability to move past its 2001 default and regain access to foreign funds.
