JEDDAH, March 27 (Reuters) - The cut in income tax paid by national oil giant Saudi Aramco to 50 percent from 85 percent brings the company in line with international benchmarks, chief executive Amin Nasser said in a statement on Monday.

Earlier, the tax was cut in a royal decree, part of preparations for an initial public offer of shares by Aramco next year, which is expected to be the world's largest equity offer.
