The Only Significant Difference Between the Provisions of International Accounting

The only significant difference between the provisions of international accounting standards as promulgated by IAS 39 and U.S. accounting standards under FASB Statement No. 115 is

A) IAS 39 requires accounting for all investments in debt securities to be on a fair value basis while SFAS No. 115 does not.
B) IAS 39 allows all unrealized gains and losses on securities valued at fair value to be reported in net income for the period while SFAS No. 115 does not.
C) IAS 39 requires trading securities to be reported on a fair value basis but not securities available for sale.
D) IAS 39 does not permit the reporting of unrealized gains and losses on securities other than trading securities to be recorded as part of equity.
