Preferred Stock

 

As of June 30, 2014, there were 335,273 shares of the Company’s 6% Convertible Exchangeable Preferred Stock (“Preferred Stock”) issued and outstanding at an issue price of $10.00 per share. Dividends on the Preferred Stock are cumulative from the date of original issuance at the annual rate of 6% of the liquidation preference of the Preferred Stock, payable quarterly on the first day of February, May, August and November, commencing February 1, 2005. Any dividends must be declared by the Company’s Board and must come from funds that are legally available for dividend payments. The Preferred Stock has a liquidation preference of $10.00 per share, plus accrued and unpaid dividends.

 

The Preferred Stock is convertible at the option of the holder at any time into the Company’s shares of common stock at a conversion rate of approximately 0.06079 shares of common stock for each share of Preferred Stock based on a price of $164.50. The Company has reserved 20,381 shares of common stock for issuance upon conversion of the remaining shares of Preferred Stock outstanding at June 30, 2014. The shares of previously-converted Preferred Stock have been retired, cancelled and restored to the status of authorized but unissued shares of preferred stock, subject to reissuance by the Board as shares of Preferred Stock of one or more series.

 

The Company may automatically convert the Preferred Stock into common stock if the closing price of the Company’s common stock has exceeded $246.75, which is 150% of the conversion price of the Preferred Stock, for at least 20 trading days during any 30-day trading period, ending within five trading days prior to notice of automatic conversion.

 

The Certificate of Designations governing the Preferred Stock provides that if the Company fails to pay dividends on its Preferred Stock for six quarterly periods, holders of Preferred Stock are entitled to nominate and elect two directors to the Board. This right accrued to the holders of Preferred Stock as of August 2, 2010 and two directors were nominated and elected at the annual meeting held on May 24, 2011.

 

The Preferred Stock has no maturity date and no voting rights prior to conversion into common stock, except under limited circumstances.

 

The Company may, at its option, redeem the Preferred Stock in whole or in part, out of funds legally available at the redemption prices per share stated below, plus an amount equal to accrued and unpaid dividends up to the date of redemption:

 

Year from November 1, 2013 to October 31, 2014   $ 10.06  
November 1, 2014 and thereafter   $ 10.00  

 

The Preferred Stock is exchangeable, in whole but not in part, at the option of the Company on any dividend payment date beginning on November 1, 2005 (the “Exchange Date”) for the Company’s 6% Convertible Subordinated Debentures (“Debentures”) at the rate of $10.00 principal amount of Debentures for each share of Preferred Stock. The Debentures, if issued, will mature 25 years after the Exchange Date and have terms substantially similar to those of the Preferred Stock. No such exchanges have taken place to date.

 

Conversion of Convertible Preferred Stock

 

During the six months ended June 30, 2013, the Company converted an aggregate of 792,460 shares of Preferred Stock into an aggregate of 1,513,653 shares of the Company’s common stock. There were no conversions of the Company’s Preferred Stock into shares of common stock during the six months ended June 30, 2014. Since the Company’s transaction with Xcyte Therapies, Inc. in 2006, holders have exchanged 1,711,540 shares of Preferred Stock into common stock as a result of arms-length negotiations between the Company and the other parties.

 

The table below provides details of the aggregate activities during the six months ended June 30, 2013:

 

    Six
Months Ended
June 30,
2013		  
Preferred shares exchanged     792,460  
Shares of common stock issued:        
At stated conversion terms     48,174  
Incremental shares issued under the exchange transaction     1,465,479  
Total shares of common stock issued     1,513,653  

 

As the Preferred stockholders received additional shares of common stock issued to them upon conversion as compared to what they would have been entitled to receive under the stated rate of exchange, the Company recorded the excess of (1) the fair value of all securities and other consideration transferred to the holders of the Preferred Stock and (2) the fair value of securities issuable pursuant to the original conversion terms as a deemed dividend resulting in an increase in the net loss attributable to common shareholders. Specifically, the Company recorded deemed dividends related to the additional shares issued under the exchange transactions of $8.4 million for the six months ended June 30, 2013.
