Reuters announced at the beginning of the week A senior U.S. regulator was “optimistic” on Monday about finding a framework for the world’s top economy to use global book keeping rules for investors to compare cross-border companies.

“We are hopeful we can put forward a model,” James Kroeker, chief accountant at the U.S. Securities and Exchange Commission (SEC), (talking to Reuters.)

With over 100 countries currently using the accounting rules from the International Accounting Standards Board (IASB), we are waiting to see if the world’s biggest capital market adopts them too.

Other heavyweights like Japan are widely expected to follow suit.

According to Reuters, Kroeker said the SEC had delayed its decision due the more urgent and heavy work of fleshing out a reform of Wall Street known as Dodd-Frank.

Work on aligning U.S. and IASB accounting rules aimed at paving the way to U.S. adoption has also taken more time, along with a review of IASB governance.

Kroeker said he will make a proposal to SEC commissioners in “coming months” on how the United States could switch, which would spark changes in how the IASB deals with national bodies.

After Kroeker has made his proposal, SEC commissioners are expected to hold a public consultation ahead of a vote, perhaps as soon as later this year. Any U.S. adoption would likely take several years.

World leaders, including U.S. President Barack Obama, called in 2009 for a single set of global accounting rules to improve transparency for investors and regulators.
