Item 1. Security and Issuer

This Schedule 13D/A constitutes the twelfth amendment to the Schedule 13D originally filed by the Reporting Persons with the Securities and Exchange Commission (the “SEC”) on February 25, 2013 and amended by Amendment No. 1, No. 2, No. 3, No. 4, No. 5, No. 6, No. 7, No. 8, No. 9, No. 10 and No. 11 filed by the Reporting Persons with the SEC on March 25, 2013, May 6, 2013, August 30, 2013, January 15, 2014, March 21, 2014, October 31, 2014, November 12, 2014, November 28, 2014, January 16, 2015, March 13, 2015 and April 20, 2015 (the “Statement”) with respect to the common stock, $10.00 par value (the “Shares”), of SPX Corporation (the “Issuer” or the “Company”). Except as specifically amended by this Schedule 13D/A, the Statement remains in full force and effect.

Item 3. Source and Amount of Funds or Other Consideration

RILLC and the Managed Accounts purchased an aggregate of 661,739 Shares for a total consideration (including brokerage commissions) of $49.0 million derived from capital of RILLC and the Managed Accounts.

The Relational LPs purchased an aggregate of 1,346,701 Shares for total consideration (including brokerage commissions) of $98.4 million derived from the capital of the Relational LPs.

Item 5. Interest in Securities of the Issuer

(a) As of the date of this Statement, the Reporting Persons beneficially owned in the aggregate 2,008,440 Shares, constituting 4.90% of the outstanding Shares. The percentage of Shares owned is based upon 40,983,795 Shares outstanding on February 13, 2015, as set forth in the Issuer’s Form 10-Q for the period ended December 31, 2014. 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	661,739	1.61	%	Sole
MC I	402,632	0.98	%	Sole
MC II	429,858	1.05	%	Sole
RFP	6,332	0.02	%	Sole
RCP	99,868	0.24	%	Sole
RI IX	115,732	0.28	%	Sole
RI XV	66,872	0.16	%	Sole
RI XVI	33,141	0.08	%	Sole
RI XX	60,222	0.15	%	Sole
RI XXIII	85,416	0.21	%	Sole
RI XXIV	1,748	0.00	%	Sole
RH 1	44,880	0.11	%	Sole

RILLC, individually and in its capacity as an investment adviser, may be deemed to possess direct beneficial ownership of the 661,739 Shares that are owned by it and the Managed Accounts. Additionally, RILLC, as the sole general partner, or sole managing member of the general partner, of each of the 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 1,346,701 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 share indirect beneficial ownership of the Shares which RILLC may beneficially own. Each of Messrs. Whitworth and Batchelder disclaims beneficial ownership of such Shares for all other purposes.

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) See item (a) above.

(c) Except as set forth in Exhibit A to this Statement, none of the Reporting Persons has effected any transactions in the Shares during the past sixty days not previously reported.

(d) No other person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares covered by this Statement, except that dividends from, and proceeds from the sale of, the Shares held by accounts managed by RILLC may be delivered to such accounts.

(e) The Reporting Persons ceased to be beneficial owners of more than 5 percent of Shares on April 27, 2015.

Item 7. Material to Be Filed as Exhibits

The following Exhibits are filed herewith:

Exhibit A - Information concerning transactions in the Shares effected by the Reporting Persons in the last 60 days not previously reported.

Signature

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
