Resources are provided on the condition that Altruistic University comply with strict specifications governing the manner in which the research is conducted and the frequency and the character of outcome reports. Altruistic University should account for the resources provided by Experimental Pharmaceuticals as:
　　a.A contribution that increases temporarily restricted net assets and is reclassified as an increase to unrestricted net assets upon satisfaction of research and reporting restrictions.
　　b.A contribution that increases permanently restricted net assets.
　　c.An exchange transaction that increases unrestricted net assets.
　　d.A contribution that increases unrestricted net assets provided the restrictions are met in the current year and the university uniformly applies this method of recognition to all similar transactions.
　　Answer:
　　1.A
　　Choice "a" is correct. Inadequate disclosure of the substantial doubt about an entity's ability to continue as a going concern is a departure from GAAP, resulting in either a qualified or adverse opinion.
　　Choices "d" and "b" are incorrect. Scope limitations result in either a qualified opinion or in a disclaimer of opinion, but not in an adverse opinion.
　　Choice "c" is incorrect. A change in accounting principle results in the use of an emphasis-of-matter paragraph following the opinion paragraph in an unmodified report, as long as the change was accounted for properly.
　　2.D
　　Choice “d” is correct. Fernwell will pay approximately $463, computed as follows:
　　Pt=D(t+1)/(R-g)
　　D(t+1)=$20*(1.05)^2
　　D(t+1)=$22.05
　　Pt=($22.05*1.05)/(0.10-0.05)=$463
　　3.B
　　Choice "B" is correct. The Year 1 return of a calendar year corporation is due on March 15, Year 2, so the statute of limitations begins on the next day, March 16, Year 2.Rule: The statute of limitations for assessments runs from the date of the filing of the return, or, if later, the due date of the return. Choices "a", "d", and "c" are incorrect, per the above rule.
　　4.C
　　Choice "C" is correct. This is an exchange transaction, which increases unrestricted net assets. The results of the clinical trials performed by Altruistic University have a commercial value to Experimental Pharmaceuticals Corporation. Resources have been provided in exchange for research results and do not constitute a contribution.
　　Choice "b" is incorrect. The transaction represents a reciprocal transfer, or exchange, not a contribution.
　　Choice "a" is incorrect. The transaction represents a reciprocal transfer, or exchange, not a contribution.
　　Choice "d" is incorrect per the above explanation.
