Toshiba Corp. is considering releasing unaudited full-year earnings results on the May 22 deadline despite having no clear prospects of approval from its auditor, according to sources close to the matter.

PricewaterhouseCoopers Aarata LLC continues to disagree with Toshiba over losses related to its U.S. nuclear unit after the auditing firm issued a disclaimer for the company's earnings result for the April-December period last month.

May 22 is the de facto deadline for the embattled conglomerate to release its earnings for the fiscal year that ended March 31.
