* New rule should lessen fair value scope for many banks
* Tweedie says IASB rules must not be moving target
* Progress on forcing banks to make earlier loss provisions

LONDON, March 16 (Reuters) - The world's top accounting bodies are still on track to thrash out a common set of rules by the middle of next year, the International Accounting Standards Board said on Tuesday.
The G20 group of countries set the ambitious deadline last year to make it simpler for cross-border companies and investors but differences over how to value some complex assets have raised concerns about the timetable.
Last month the U.S. Securities and Exchange Commission said it would commit to a new work plan that would delay any move to international standards until at least 2015. [nN24179793]
The IASB, whose rules are used by listed companies in over 115 countries, including the European Union but not the United States, said it has stepped up meetings with its U.S. peer, the Financial Accounting Standards Board.
"In our soon to be published report, the Boards will state that despite the challenging technical issues to resolve, we remain on schedule to achieve the June 2011 target," Tweedie told EU finance ministers in a statement made available to the media.
"These intensive discussions are achieving positive results. We plan to publish seven joint proposals in the next quarter. The Boards individually will also propose other changes to bring their own standards in line with each other," Tweedie said.
The G20 also called for a simplification of the fair value or mark-to-market accounting rules used by standard setters.
NO MOVING TARGET
The IASB has already simplified its fair value standard, renamed IFRS 9, but the EU has yet to endorse it for use in the 27-nation bloc.
The original rule was blamed for amplifying fallout from the credit crunch as it obliged banks to price assets at the depressed going rate, forcing them to make huge writedowns and find fresh capital.
Some countries like France worry the reformed rule will not lead to less use of fair value and that it may need further changes.
"For a traditional bank, being one that takes deposits and lends money to customers that it holds to collect principal and interest, we expect IFRS 9 to result in fewer rather than more items being measured at fair value," Tweedie said.
He told ministers that several countries were already adopting the revised fair value rule and the IASB did not want its standards to be a "constantly moving target".
"By completing our convergence work in 2011, the IASB will provide a period of stability of accounting standards for newly adopting countries, similar to the 'stable platform' given to European companies and investors between 2004 and 2009," Tweedie said.
The U.S. FASB is expected to unveil a proposed reform to its fair value rule that banks fear will lead to a widening of its scope, a move that will make convergence trickier.
The G20 also wants banks to make earlier provisions for losses and lessen the need for more public bailouts but some accountants argue this could muddy the picture for investors.
Tweedie said the IASB is discussing the possibility of providing regulators with additional information without compromising transparency.
"Specifically, we have suggested... that an additional regulatory income statement could be required. The exact content would be agreed between the IASB and prudential regulators," Tweedie said.
"Prudential supervisors could use this statement as a basis for imposing relevant restrictions on distributions or compensation," Tweedie added.
