Item 4. Ownership
The securities reported herein are beneficially owned by one or more open‑end investment
companies or other managed accounts that are investment management clients of ClearBridge
Investments, LLC ("CIL"), an indirect wholly owned subsidiary of Franklin Resources, Inc.
("FRI"). When an investment management contract (including a sub‑advisory agreement)
delegates to CIL investment discretion or voting power over the securities held in the
investment advisory accounts that are subject to that agreement, FRI treats CIL as having
sole investment discretion or voting authority, as the case may be, unless the agreement
specifies otherwise. Accordingly, CIL reports on Schedule 13G that it has sole investment
discretion and voting authority over the securities covered by any such investment
management agreement, unless otherwise noted in this Item 4. As a result, for purposes of
Rule 13d‑3 under the Act, CIL may be deemed to be the beneficial owner of the securities
reported in this Schedule 13G.
Beneficial ownership by investment management subsidiaries and other affiliates of FRI
is being reported in conformity with the guidelines articulated by the SEC staff in
Release No. 34‑39538 (January 12, 1998) relating to organizations, such as FRI, where
related entities exercise voting and investment powers over the securities being
reported independently from each other. The voting and investment powers held by CIL are
exercised independently from FRI (CIL’s parent holding company) and from all other
investment management subsidiaries of FRI (FRI, its affiliates and investment management
subsidiaries other than CIL are, collectively, “FRI affiliates”). Furthermore, internal
policies and procedures of CIL and FRI affiliates establish informational barriers that
prevent the flow between CIL and the FRI affiliates of information that relates to the
voting and investment powers over the securities owned by their respective investment
management clients. Consequently, CIL and the FRI affiliates report the securities over
which they hold investment and voting power separately from each other for purposes of
Section 13 of the Act.
CUSIP NO. 45253H101 13G Page 5 of 7
Charles B. Johnson and Rupert H. Johnson, Jr. (the "Principal Shareholders") each own in
excess of 10% of the outstanding common stock of FRI and are the principal stockholders
of FRI. However, because CIL exercises voting and investment powers on behalf of its
investment management clients independently of FRI affiliates, beneficial ownership of the
securities reported by CIL is not attributed to the Principal Shareholders. CIL
disclaims any pecuniary interest in any of the securities reported in this Schedule 13G.
In addition, the filing of this Schedule 13G on behalf of CIL should not be construed as
an admission that it is, and it disclaims that it is, the beneficial owner, as defined
in Rule 13d‑3, of any of such securities.
Furthermore, CIL believes that it is not a "group" with FRI affiliates, the Principal
Shareholders, or their respective affiliates within the meaning of Rule 13d‑5 under the
Act and that none of them is otherwise required to attribute to any other the
beneficial ownership of the securities held by such person or by any persons or
entities for whom or for which CIL or the FRI affiliates provide investment management
services.

percent of the class of securities, check the following [X].
Item 6. Ownership of More than Five Percent on Behalf of Another Person
The clients of ClearBridge Investments, LLC, including investment companies
registered under the Investment Company Act of 1940 and other managed accounts,
have the right to receive or power to direct the receipt of dividends from, and
the proceeds from the sale of, the securities reported herein.
