This Statement is also being filed by California State Teachers’ Retirement System (“CalSTRS”), a California Government Employee Benefit plan. The principal business of CalSTRS is to provide retirement related benefits and services to teachers in public schools and community colleges in California.

CalSTRS and the Relational Entities are filing this statement jointly as they have formed a group with the purpose of supporting a shareholder proposal. See Item 4 below for further discussion of such shareholder proposal, which is incorporated into this Item 2 by reference.

The Relational Entities and CalSTRS together are the “Reporting Persons”.

During the last five years, none of the Reporting Persons has been (i) convicted in a criminal proceeding (excluding traffic violations and similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction, and as a result of such proceeding, was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Messrs. Whitworth and Batchelder are citizens of the United States.

Item 3.

Source and Amount of Funds or Other Consideration

The Reporting Persons purchased an aggregate of 7,744,440 Shares for total consideration (including brokerage commissions) of $359 million derived from their working capital.

Item 4.

Purpose of Transaction

Item 4 is hereby amended and supplemented as follows:

The Company since held its 2013 annual meeting of shareholders at which a majority and, more importantly, a significant majority of the independent, non-affiliated shareholders, voted in favor of the CalSTRS’, a Reporting Person, shareholder proposal recommending that “the board of directors and management act expeditiously to engage an investment banking firm to effectuate a spinoff of the Steel business into a separately traded public company.”

The Reporting Persons have expressed their belief that the Company should promptly carry out the will of its shareholders in order to unlock value. On June 10, 2013, the Company announced the board’s decision to set up a strategy committee comprised of independent directors, with Goldman Sachs as an advisor, to evaluate the potential spin-off of the Steel business.

The Reporting Persons have since met with members of the special committee and representatives of Goldman Sachs and believe that the Company has chosen an appropriate process and are confident if the board of directors are apprised of the proper analysis that the board will conclude that splitting the Steel and Bearings businesses is in the long term best interest of shareholders.

Item 5.

Interest in Securities of the Issuer

(a) As of the date of this Statement, the Reporting Persons beneficially own in the aggregate 7,744,440 Shares, constituting approximately 8.15% of the outstanding Shares. The percentage of Shares owned is based upon 95,006,238 Shares reported to be outstanding on June 30, 2013, as set forth in the Company’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2013. The Reporting Persons may be deemed to have direct beneficial ownership of the Shares as follows:

NAME	NUMBER OF SHARES	% OF OUTSTANDING SHARES	VOTING AND DISPOSITIVE POWER
RILLC	706,692	0.74%	Sole
MC I	3,338,672	3.51%	Sole
MC II	2,113,337	2.22%	Sole
RCP	70,542	0.07%	Sole
RFP	6,856	0.01%	Sole
RH 1	12,326	0.01%	Sole
RI IX	132,550	0.14%	Sole
RI XV	68,888	0.07%	Sole
RI XVI	8,104	0.01%	Sole
RI XX	59,123	0.06%	Sole
RI XXIII	83,950	0.09%	Sole
RI XXIV	17,080	0.02%	Sole
RCF I	888,415	0.94%	Sole
CalSTRS	237,905	0.25%	Shared

RILLC, individually and in its capacity as an investment adviser, may be deemed to possess direct beneficial ownership of the 706,692 Shares that are owned by it and the Managed Accounts. Additionally, RILLC, as the sole general partner, of each of Relational LPs may be deemed to beneficially own (as that term is defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended) the 6,799,843 Shares beneficially owned by the Relational LPs because the limited partnership agreements of the Relational LPs specify that RILLC has sole investment discretion and voting authority with respect to those Shares.

Each of Messrs. Whitworth and Batchelder, as Principals of RILLC, may be deemed to have indirect beneficial ownership of the Shares which RILLC may beneficially own. Each of Messrs. Whitworth and Batchelder disclaims beneficial ownership of such Shares except to the extent of his pecuniary interest therein.

CalSTRS beneficially owns the underlying shares identified above and has sole voting authority over such shares. CalSTRS may be deemed to share the dispositive power over 82,774 shares that it beneficially owns with certain of its external asset managers.

To the best of the knowledge of each of the Reporting Persons, other than as set forth above, none of the persons named in Item 2 is the beneficial owner of any Shares.

(b) CalSTRS has the sole power to vote or to direct the vote of all of the Shares it beneficially owns as disclosed in item (a). Except for 82,774 Shares, CalSTRS has the sole power to dispose or to direct the disposition of all Shares it beneficially owns as disclosed in item (a). CalSTRS shares the power to dispose or to direct the disposition of 82,774 Shares it beneficially owns with certain of its external managers, as follows:

Name of investment manager		Number of shares

BlackRock Inc.		42,587

Phocas Financial Corporation		10,087

First Quadrant, L.P.		28,800

OakBrook Investments, LLC		1,300

The principal business of BlackRock Institutional Trust Company, N.A. (“BlackRock”) is to provide diversified investment management and securities lending services to institutional clients, intermediary and individual investors through various investment vehicles. Its business address is 400 Howard Street, San Francisco, CA 94105. BlackRock informed CalSTRS that, on January 20, 2012, BlackRock entered into an Offer of Settlement (the “Agreement”) with the CFTC and consented to the entry of an Order, which makes findings and imposes remedial sanctions against BlackRock. Without admitting or denying wrongdoing, BlackRock agreed to the imposition of a $250,000 penalty and the entry of the Order to resolve allegations by the CFTC that two trades by BlackRock violated Section 4c(a)(1) of the Commodity Exchange Act and CFTC Regulation 1.38(a). Blackrock also agreed to refrain from any further violations of the above-mentioned statutory provisions.
