Note 10 – Stockholders’ Equity:

During 2011, we retired 398,068 shares of our treasury stock and allocated its aggregate $796,000 cost to common stock at par value and additional-paid-in-capital. In addition, certain of these shares had previously been held by one of our subsidiaries prior to their cancellation, and we incurred an income tax charge of $456,000 (also allocated to additional paid-in capital) when such shares were transferred to Keystone immediately prior to their cancellation.

In May 2011, we filed a preliminary registration statement on Form S-1 with the SEC in connection with a proposed distribution of non-transferable subscription rights to our common stockholders. The proposed offering contemplated participation by Contran as a subscribing party to the fullest extent possible. The commencement of and Contran’s participation in the proposed offering was subject to, among other things, Contran and us reaching agreement on the terms of the proposed offering. Prior to reaching such agreement, Contran purchased additional shares of our common stock from a third-party stockholder in a private transaction. As a result of such purchase, Contran indicated to us it no longer intended to subscribe for our shares in connection with the proposed offering. Thus, we cancelled the offering.

In settlement of any alleged short-swing profit derived from the sale of our stock by the third-party stockholder to Contran, as calculated pursuant to Section 16(b) of the Securities Exchange Act of 1934, as amended, the third-party stockholder remitted approximately $106,000 to us during the third quarter of 2011. Additionally, in accordance with an agreement between Contran and us regarding the proposed stock rights offering, Contran reimbursed us for certain costs of the offering amounting to $161,000. We recorded both of these transactions, net of related income taxes, as capital contributions, increasing our additional paid-in capital.
