Debt Disclosure [Abstract] |
Subordinated Debenture | Subordinated Debenture On June 28, 2013, the Company entered into a subordinated debenture purchase agreement with a third party and issued a subordinated debenture in the principal amount of $3.0 million, which bears interest at a fixed annual rate of 8.00%, and is scheduled to mature on June 28, 2021; however, the Company can repay the debenture without premium or penalty at any time after June 28, 2016. The debenture qualifies for treatment as Tier 2 capital for regulatory capital purposes. The purchase agreement and the debenture contain customary subordination provisions and events of default; however, the right of the investor to accelerate the payment of the debenture is limited to bankruptcy or insolvency. As partial inducement for the third party to purchase the debenture, the Company issued to the third party a warrant to purchase up to 48,750 shares of common stock at an initial per share exercise price equal to $19.33. The warrant became exercisable on June 28, 2014 and, unless previously exercised, will expire on June 28, 2021. The Company has the right to force an exercise of the warrant after the debenture has been repaid in full if the 20-day volume-weighted average price of a share of its common stock exceeds $30.00. The Company used the Black-Scholes option pricing model to assign a fair value of $0.3 million to the warrant as of June 28, 2013. The following assumptions were used to value the warrant: a risk-free interest rate of 0.66% per the U.S. Treasury yield curve in effect at the date of issuance, an expected dividend yield of 1.19% calculated using the dividend rate and stock price at the date of the issuance, and an expected volatility of 34% based on the estimated volatility of the Company’s stock over the expected term of the warrant, which is estimated to be three years.
