NEW YORK (TheStreet) -- Notable companies releasing quarterly earnings reports Friday include oil companies Exxon Mobil (XOM) - Get Report and Chevron (CVX) - Get Report, while key economic data includes the employment cost index.

On the earnings front, Royal Caribbean (RCL) - Get Report, Newell Rubbermaid (NWL) - Get Report, security systems company Tyco International (TYC) and data storage provider Seagate Technology (STX) - Get Report are also expected to report before the opening bell.

Exxon Mobil is the latest oil name to report its earnings results amid the global oversupply and is expected to post a year-over-year decline on both the top and bottom lines. Wall Street is forecasting earnings of $1.12 a share on revenue of $72.48 billion, according to analysts surveyed by Thomson Reuters. That equates to declines of 46% and 35%, respectively.

Irving, Texas-based Exxon Mobil is the largest publicly traded international oil and gas company and holds an industry-leading inventory of resources. The company is the largest refiner and marketer of petroleum products.

On the economic calendar, the employment cost index (ECI), the Chicago Purchasing Manager Index (PMI) and the consumer sentiment are all expected.

The ECI is a measure of total employee compensation costs, including wages and salaries as well as benefits. For the PMI, the Institute For Supply Management - Chicago compiles a survey and a composite diffusion index of business conditions in the Chicago area. And, the University of Michigan's Consumer Survey Center questions 500 households each month on their financial conditions and attitudes about the economy to compile the consumer sentiment level.
