On October 20, 2011, pursuant to the Merger Agreement, Merger Sub merged with and into the Company (the “Merger”), with the Company surviving as an indirect wholly owned subsidiary of Parent.

The disclosure under Item 5.01 below is incorporated herein by reference.

The information contained in Item 1.02 of this Current Report on Form 8-K is incorporated by reference into this Item 2.04.

The consummation of the Offer (as defined below) constituted a “Change in Control” under the Master Note Purchase Agreement, dated as of September 9, 2010 (as amended, supplemented or otherwise modified from time to time, the “Master Note Purchase Agreement”) by and among the Company and each of the purchasers party thereto pursuant to which the Company issued to the purchasers 4.00% Notes in the aggregate principal amount of $250 million. Pursuant to the terms of the Master Note Purchase Agreement, the Company is required to offer to prepay all, but not less than all, of the 4.00% Notes held by each holder at a prepayment amount of 100% of the principal amount of the 4.00% Notes together with any interest accrued to the date of prepayment, but without any penalty or premium. Such offer to prepay must be given by the Company to each holder within within five business days of such “Change in Control”, and payment to any holders that accept such offer must be made between thirty and sixty days after the date of such offer.

In addition, the consummation of the Offer (as defined below) constituted a “Change in Control” under the Note Purchase and Private Shelf Agreement, dated August 28, 2009 (as amended, supplemented or otherwise modified from time to time, the “Note Purchase Agreement”) by and among the Company, Prudential Investment Management, Inc. and each of the purchasers party thereto pursuant to which the Company issued to the purchasers 6.70% Notes in the aggregate principal amount of $75 million.

Item 3.01.

Notice of Delisting or Failure to Satisfy a Continuing Listing Rule or Standard; Transfer of Listing.

In connection with the closing of the Merger, the Company notified the New York Stock Exchange (the “NYSE”) on October 20, 2011 of the closing of the Merger and requested that the NYSE effect a trading suspension of the shares of the Company’s common stock, par value $1.00 per share (“Company Common Stock”). As a result, shares of Company Common Stock will cease trading on the NYSE, and the NYSE will file with the Securities and Exchange Commission (the “SEC”) a notification of removal from listing on Form 25 to report that the shares of Company Common Stock are no longer listed on the NYSE.

Item 3.03.

Material Modification to Rights of Security Holders.

The information contained in Item 5.01 of this Current Report on Form 8-K is incorporated by reference into this Item 3.03.

Item 5.01.

Changes in Control of Registrant.

As previously disclosed in the Prior Report, on July 10, 2011 the Company entered into the Merger Agreement with Parent and Merger Sub, pursuant to which Merger Sub launched a tender offer to purchase all of the outstanding shares of Company Common Stock for $47.20 per share, net to the seller in cash, upon the terms and subject to the conditions set forth in the Offer to Purchase dated July 15, 2011 and the related Letter of Transmittal (the “Offer”). The Merger Agreement also provides that, among other things, following completion of the Offer, and subject to the satisfaction or waiver of certain conditions, Merger Sub will merge with and into the Company in accordance with the Virginia Stock Corporation Act of the Commonwealth of Virginia.

The initial offering period of the Offer (as previously extended, the “Initial Offering Period”) and the withdrawal rights expired at 12:00 midnight, New York City time, on October 14, 2011, at which time, based on the information provided to Parent by BNY Mellon Shareowner Services, the depositary for the Offer (the “Depository”), approximately 23,372,120 shares of Company Common Stock were validly tendered and not properly withdrawn prior to the expiration of the Initial Offering Period, including 2,703,910 shares of Company Common Stock subject to guaranteed delivery procedures. Merger Sub accepted all validly tendered and not properly withdrawn shares of Company Common Stock for payment. The shares of Company Common Stock that were validly tendered and not properly withdrawn represented approximately 91.9% percent of the Company’s outstanding shares. On October 17, 2011, Merger Sub commenced a subsequent offering period (the “Subsequent Offering Period”) in connection with the Offer for all remaining shares of Company Common Stock to permit shareholders who have not yet tendered their shares the opportunity to do so. The Subsequent Offering Period expired at 12:00 midnight, New York City time, on Wednesday, October 19, 2011, at which time, based on the information provided to Parent by the Depository, an additional 1,023,756 shares of Company Common Stock were validly tendered prior to the expiration of the Subsequent Offering Period.

On October 20, 2011, following the expiration of the Subsequent Offering Period, Parent paid for the shares validly tendered in the Offer and caused the consummation of the Merger in accordance with the terms of the Merger Agreement. Because Merger Sub owned more than 90% of the outstanding shares of Company Common Stock following the expiration of the Subsequent Offering Period, Parent and Merger Sub effected the Merger as a “short form” merger without the need for a meeting or vote of the Company’s shareholders, as permitted by Virginia law. As contemplated by the Merger Agreement, at the effective time of the Merger on October 20, 2010 (the “Effective Time”), each share of Company Common Stock not tendered in the Offer and outstanding immediately prior to the Effective Time (other than shares owned by the Company’s subsidiaries or by Parent, Merger Sub or any of their respective subsidiaries) was converted into the right to receive an amount in cash, without interest thereon and less any required withholding taxes, equal to $47.20 per share of Company Common Stock.

Parent provided Merger Sub with sufficient funds to purchase all shares of Company Common Stock that were validly tendered in the Offer and not properly withdrawn and provided funding for the Merger.

As a result of the consummation of the Merger and the removal from listing of the Company Common Stock from the NYSE, the Company intends to file with the SEC a certification on Form 15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), requesting the deregistration of the Company Common Stock and the suspension of the Company’s reporting obligations under Sections 13 and 15(d) of the Exchange Act.

For information regarding changes with respect to the directors of the Company, please see Item 5.02 of this Current Report on Form 8-K, which is incorporated by reference into this Item 5.01.

The foregoing summary of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement attached as Exhibit 2.1 to the Prior Report, which is incorporated by reference into this Item 5.01.
