4. Dividendfactsheet 2008
NYSE: PEG
PSEG Dividends – A New Century
PSEG is continuing its remarkable record of paying common dividends. The year 2008 represents the 101st year
PSEG or its predecessor company will be paying dividends to the holders of its common stock. PSEG has paid dividends
each year since 1907 – a record only matched by General Electric and Exxon Mobil.
The board of directors of PSEG declared a 10% increase in the quarterly common dividend on January 15,
2008 as it also announced a 2-for-1 stock split. On a post-split basis, the quarterly dividend was raised to 32.25
cents per share from 29.25 cents per share. The new annual common dividend rate is $1.29 per share on a post-split basis.
This is the fifth consecutive year that PSEG has raised its common dividend. This latest increase by the board
resets the dividend to a payout of earnings in the middle of a range (40-50%) which provides flexibility for growth and
investment given PSEG’s mix of earnings and assets. The largest contributor to PSEG’s earnings is PSEG Power, a com-
petitive power generation company, followed by PSE&G, a regulated electric and gas transmission and distribution
company, and, to a lesser extent PSEG Energy Holdings. The resetting of the dividend provides PSEG with flexibility for
dividend growth and new investment. (All future changes in the common dividend are subject to board approval.)

*Annual dividend rate reflects 2:1 stock split effective on February 4, 2008.
**2008 yield calculation based on PEG stock price as of March 30, 2008 (adjusted for stock split); payout ratio based on mid-point of 2007 and 2008 earnings guidance.
Payout ratio = percent of income paid to shareholders as common dividends; Yield = annual dividend as a percent of the average stock price of the year.
