Stock options [Abstract] |
Stock options [Text Block] | Note 11 - Stock-based compensation The Company has stock-based compensation awards that can be granted to eligible employees, officers or directors.
| 2016 |  | 2015 |
Stock-based compensation (benefit) expense |  | ($540 | ) |  | $116 |
Restricted stock based compensation expense |  | $1,243 |  |  | $470 |
Stock-based compensation was a benefit year-to-date due to cancellations. A majority of these cancellations related to former employees from the discontinued operations. Stock options On June 20, 2013, the stockholders approved the 2013 Omnibus Stock Incentive Plan ("Omnibus Plan"). Under the Omnibus Plan, 350,000 shares of common stock are reserved for issuance to employees, officers, and directors of, and other individuals providing bona fide services to or for, the Company and its affiliates. In addition, on January 31, 2014 and each January 31 thereafter until January 31, 2023, the aggregate number of shares that may be issued with respect to Awards pursuant to the terms of this Plan will be increased by the number equal to 2% of the aggregate amount of common stock outstanding as of such date, provided, however, the maximum number of additional shares that may be issued pursuant to this sentence will not exceed 400,000. The Omnibus Plan permits the granting of stock options (including incentive stock options qualifying under Code section 422 and nonstatutory stock options), stock appreciation rights, restricted or unrestricted stock awards, restricted stock units, performance awards, deferred stock awards, other stock-based awards, or any combination of the foregoing. Awards will be valued at the Company's closing stock price on the date of grant. Options vest ratably over four years and are exercisable for up to ten years from the date of grant. To cover the exercise of vested options, the Company issues new shares from its authorized but unissued share pool. The Company calculates all stock compensation expense based on the grant date fair value of the option and recognizes expense on a straight-line basis over the four-year vesting period of the option. The fair value of each option award was estimated on the date of grant using the Black-Scholes option-pricing model that used the assumptions noted in the following table. The principal variable assumptions utilized in valuing options and the methodology for estimating such model inputs include:
1. | R isk-free interest rate - an estimate based on the "Market yield on U.S. Treasury securities at the rate for the period described in assumption 3 below, quoted on investment basis" for the end of week closest to the stock option grant date, from the Federal Reserve website;
2. | E xpected volatility - an estimate based on the historical volatility of PPIH common stock's weekly closing stock price for the expected life; and
3. | E xpected life of the option - an estimate based on historical experience including the effect of employee terminations.
|  | 2016 |  | 2015 |
1. | Risk-free interest rate | 1.2 | % | 1.7 | %
2. | Expected volatility | 43.2 | % | 43.4 | %
3. | Expected life in years | 5.0 |  | 5.0 |
4. | Dividend yield | — | % | — | %
The following summarizes the activity related to options outstanding under all plans for the years ended January 31, 2016 and 2017:

Options exercisable on January 31, 2017 | 450 |  | $11.92 | 3.9 | $465
The weighted average fair value of options granted, net of options surrendered, during 2016 and 2015 are estimated at $2.85 and $2.54, per share, respectively, on the date of grant.
Unvested options outstanding | Options |  | Weighted-average grant date fair value |  | Aggregate intrinsic value
Outstanding on January 31, 2016 | 166 |  | $9.51 | $3
Granted | 22 |  | 7.33 |  |
Vested | (72 | ) |  |
Expired or forfeited | (42 | ) | 8.98 |  |
Outstanding on January 31, 2017 | 74 |  | $9.31 | $69
Based on historical experience the Company expects 85% of these options to vest. As of January 31, 2017, there was $0.2 million of unrecognized compensation cost related to unvested stock options granted under the plans. That cost is expected to be recognized over the weighted-average period of 2.0 years.
