Redeemable Preferred Stock and Warrants
Note 7 — Redeemable Preferred Stock and Warrants
     The Company may accrue dividends on its Series A Preferred Stock rather than paying cash prior to July 1, 2013. Whenever dividends are accrued, the liquidation preference on the Series A Preferred Stock is increased by a similar amount, additional warrants to purchase shares of PostRock common stock are issued and additional shares of Series B Preferred Stock are issued as well. The Company records the increase in liquidation preference and the issuance of additional warrants by allocating their relative fair values to the amount of accrued dividends. The allocation results in an increase to the Company’s temporary equity related to the Series A Preferred Stock and an increase to additional paid in capital related to the additional warrants issued. The increase to additional paid in capital related to additional warrants issued was $745,000 and $752,000 in the first and second quarters of 2011, respectively.
     The following tables describe the changes in temporary equity, currently comprised of the Series A Preferred Stock (in thousands except share amounts), and in outstanding warrants:
