TIAA-CREF Investment Management, LLC ("Investment Management") acts as an
investment adviser to the College Retirement Equities Fund ("CREF"), a
registered investment company, and may be deemed to be a beneficial owner of
5,391,450 shares of Issuer's common stock owned by CREF. Teachers Advisors, Inc.
("Advisors") is the investment adviser to four registered investment companies,
TIAA-CREF Institutional Mutual Funds ("Institutional Funds"), TIAA-CREF Life
Funds ("Life Funds"), TIAA-CREF Mutual Funds ("Mutual Funds") and TIAA Separate
Account VA-1 ("VA-1"), as well as the TIAA-CREF Asset Management Commingled
Funds Trust I ("TCAM Funds"), and may be deemed to be a beneficial owner of
363,921 shares of Issuer's common stock owned by Institutional Funds, Life
Funds, Mutual Funds, VA-1 and TCAM Funds. Investment Management and Advisors are
reporting their combined holdings for the purpose of administrative convenience.
These shares were acquired in the ordinary course of business, and not with the
purpose or effect of changing or influencing control of the Issuer. Each of
Investment Management and Advisors expressly disclaims beneficial ownership of
the other's securities holdings and each disclaims that it is a member of a
"group" with the other.
