It is heartening to note that PSO, our leading national petroleum company, has been accorded recognition as one of the premier corporate organisations of the Muslim world. The company has recently been given the 29th ranking by Dinar Standard in its 5th annual ranking of the top 100 businesses of the Muslim world. This is encouraging news for the nation which should provide us with the necessary impetus to strive for excellence in our respective fields so that our organisations are also recognised not just among the top 100 from the 57 OIC countries but in the entire global community. PSO is a stellar organisation indeed with a strong product line up, excellent service, and a commitment to corporate social responsibility. The company has delivered on the expectations of the nation time and again. -RAZA KHAN, Karachi, via e-mail, March 20.
