Under FASB Statement of Financial Accounting Concepts
5, which of the following items would cause earnings to
differ from comprehensive income for an enterprise in an industry
not having specialized accounting principles?

(a) Per SFAC 5, earnings and comprehensive income
have the same broad components—revenues, expenses, gains,
and losses—but are not the same because certain classes of gains
and losses are excluded from earnings. Changes in market values
of investments in marketable equity securities classified as
available-for-sale securities are included in comprehensive income,
but are excluded from earnings until realized. Answers
(b), (c), and (d) are incorrect because they would be
included in both earnings and comprehensive income. Note that
unrealized gains and losses on marketable equity securities classified
as trading securities are included in earnings. This treatment
is in accordance with SFAS 115.
