CUSIP NO. 00101B103

The following constitutes Amendment No. 27 to the Schedule 13D filed by the undersigned (“Amendment No. 27”). This Amendment No. 27 amends the Schedule 13D as specifically set forth.

Item 3.

Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated to read as follows:

The aggregate purchase price of the 35,370,561 Shares owned by Steel Partners II is approximately $112,608,454, including brokerage commissions. The Shares owned by Steel Partners II were acquired with partnership funds.

The Shares beneficially owned by Messrs. Howard and Quicke were awarded to them in their capacities as directors of the Issuer.

Set forth on Schedule B annexed to Amendment No. 21 to the Schedule 13D (“Schedule B”) is the aggregate purchase price of the Shares beneficially owned, if any, by each of the directors of Steel Holdings GP.

Steel Partners II effects purchases of securities primarily through margin accounts maintained for it with prime brokers, which may extend margin credit to it as and when required to open or carry positions in the margin accounts, subject to applicable federal margin regulations, stock exchange rules and the prime brokers’ credit policies. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the accounts.

Item 5.

Interest in Securities of the Issuer.

Item 5(a) is hereby amended and restated to read as follows:

(a) The aggregate percentage of Shares reported owned by each person named herein is based upon 120,324,013 Shares outstanding, which is the total number of Shares outstanding as of August 4, 2010 as reported in the Issuer’s Form 10-Q filed with the Securities and Exchange Commission on August 11, 2010.

As of the close of business on August 24, 2010, Steel Partners II owned directly 35,370,561 Shares, constituting approximately 29.4% of the Shares outstanding. By virtue of their relationships with Steel Partners II discussed in further detail in Item 2, each of Steel Holdings, Partners LLC and Warren G. Lichtenstein may be deemed to beneficially own the Shares owned by Steel Partners II.

As of the close of business on August 24, 2010, Jack L. Howard beneficially owned 18,750 Shares underlying Restricted Stock Awards, 6,250 Shares of which have vested, and beneficially owned an additional 21,875 Shares underlying Non-Qualified Stock Options that are exercisable within 60 days of the date hereof, constituting in the aggregate less than 1% of the Shares outstanding.

As of the close of business on August 24, 2010, John J. Quicke beneficially owned 18,750 Shares underlying Restricted Stock Awards, 6,250 Shares of which have vested, and beneficially owned an additional 21,875 Shares underlying Non-Qualified Stock Options that are exercisable within 60 days of the date hereof, constituting in the aggregate less than 1% of the Shares outstanding.

CUSIP NO. 00101B103

Set forth on Schedule B is the aggregate number and percentage of Shares beneficially owned, if any, by each of the directors of Steel Holdings GP. Unless otherwise indicated thereon, each of the persons listed on Schedule B has (i) the sole power to vote and dispose of the Shares they beneficially own, if any, and (ii) the right to receive, or the power to direct the receipt of dividends from, or proceeds from the sale of, the Shares that they beneficially own, if any.

Each of the Reporting Persons, as a member of a “group” with the other Reporting Persons for purposes of Rule 13d-5(b)(1) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), may be deemed to beneficially own the Shares owned by the other Reporting Persons.

Item 5(c) is hereby amended to add the following:

(c) Schedule C annexed hereto lists all transactions in the Shares by the Reporting Persons since the filing of Amendment No. 26 to the Schedule 13D. All of such transactions were effected in the open market.
