第3题：

(b) Discuss the nature of the following issues in developing IFRSs for SMEs.

(i) The purpose of the standards and the type of entity to whom they should apply. (7 marks)


正确答案：
(b) There are several issues which need to be addressed when developing IFRSs for SMEs:
(i) The purpose of the standards and type of entity
The principal aim of the development of an accounting framework for SMEs is to provide a framework which generates
relevant, reliable and useful information. The standards should provide high quality and understandable accounting
standards suitable for SMEs globally. Additionally they should meet the needs set out in (a) above. For example reduce
the financial reporting burden for SMEs. It is unlikely that one of the objectives would be to provide information for
management or meet the needs of the tax authorities as these bodies will have specific requirements which would be
difficult to meet in an accounting standard. However, it is likely that the standards for SMEs will be a modified version
of the full IFRSs and not an independently developed set of standards in order that they are based on the same
conceptual framework and will allow easier transition to full IFRS if the SME grows or decides to become a publicly listed
entity.
It is important to define the type of entity for which the standards are intended. Companies who have issued shares to
the public would be expected to use full IFRS. The question arises as to whether SME standards should apply to all
unlisted entities or just those listed entities below a certain size threshold. The difficulty with size criteria is that it would
have to apply worldwide and it would be very difficult to specify such criteria. Additionally some unlisted companies, for
example public utilities, have a reporting obligation that is equivalent to that of a listed company and should follow full
IFRS.
The main characteristic which distinguishes SMEs from other entities is the degree of public accountability. Thus the
definition of what constitutes an SME could revolve around those entities that do not have public accountability.
Indicators of public accountability will have to be developed. For example, a listed company or companies holding assets
in a fiduciary capacity (bank), or a public utility, or an entity with economic significance in its country. Thus all entities
that do not have public accountability may be considered as potential users of IFRSs for SMEs.
Size may not be the best way to determine what is an SME. SMEs could be defined by reference to ownership and themanagement of the entity. SMEs are not necessarily just smaller versions of public companies.

正确答案：A
Update 语句用于修改表中的数据,语法：UPDATE 表名称 SET 列名称 = 新值 WHERE 列名称 = 某值，根据语法，表名称应该为SC，GRADE=GRADE*1．05，条件为SC．GRADE>=80，后面的60到80分的同理。
