SIGNATURE VINCENT P. CORTI
TITLE SECRETARY
November 30, 1998
To the Board of Directors of
Capital Income Builder, Inc.
In planning and performing our audit of the financial statements
of Capital Income Builder, Inc. (the "Fund") for the year ended
October 31, 1998, we considered its internal control, including
control activities for safeguarding securities, in order to
determine our auditing procedures for the purpose of expressing
our opinion on the financial statements and to comply with the
requirements of Form N-SAR, not to provide assurance on internal
control.
The management of the Fund is responsible for establishing and
maintaining internal control. In fulfilling this
responsibility, estimates and judgments by management are
required to assess the expected benefits and related costs of
controls. Generally, controls that are relevant to an audit
pertain to the entity's objective of preparing financial
statements for external purposes that are fairly presented in
conformity with generally accepted accounting principles. Those
controls include the safeguarding of assets against unauthorized
acquisition, use or disposition.
Because of inherent limitations in internal control, errors or
fraud may occur and not be detected. Also, projection of any
evaluation of internal control to future periods is subject to
the risk that it may become inadequate because of changes in
conditions or that the effectiveness of the design and operation
may deteriorate.
Our consideration of internal control would not necessarily
disclose all matters in internal control that might be material
weaknesses under standards established by the American Institute
of Certified Public Accountants. A material weakness is a
condition in which the design or operation of one or more of the
internal control components does not reduce to a relatively low
level the risk that misstatements caused by errors or fraud in
amounts that would be material in relation to the financial
statements being audited may occur and not be detected within
a timely period by employees in the normal course of performing
their assigned functions. However, we noted no matters
involving internal control and its operation, including controls
for safeguarding securities, that we consider to be material
weaknesses as defined above as of October 31, 1998.
This report is intended solely for the information and use of
management and the Board of Directors of the Fund and the
Securities and Exchange Commission.
