Fair Value Disclosures [Abstract] |
Fair value measurements | 8.Fair value measurements A fair value measurement is determined based on the assumptions that a market participant would use in pricing an asset or liability. A three-tiered hierarchy draws distinctions between market participant assumptions based on (i) observable inputs such as quoted prices in active markets (Level 1), (ii) inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2) and (iii) unobservable inputs that require the Company to use present value and other valuation techniques in the determination of fair value (Level 3). The following table sets forth our financial assets and liabilities as of April 30, 2017 that are measured on a recurring basis during the period, segregated by level within the fair value hierarchy:
|  | Level 1 |  | Level 2 |  | Level 3 |  | Total |
|  | (All amounts are pres e nted in thousands) |
Assets at Fair Value: |  |  |  |  |  |  |  |  |  |  |  |  |

Total assets at fair value |  | $ | 35,747 |  |  | - |  |  | - |  | $ | 35,747 |
| (1) |  | The investment in Limoneira Company consists of marketable securities in the Limoneira Company stock. We currently own approximately 12% of Limoneira’s outstanding common stock. These securities are measured at fair value by quoted market prices. Limoneira’s stock price at April 30, 2017 and October 31, 2016 equaled $20.68 per share and $19.69 per share. Unrealized gains and losses are recognized through other comprehensive income. Unrealized investment holding gains arising during the three months ended April 30, 2017 and 2016 was $6.4 million and $9.2 million. Unrealized investment holding gains arising during the six months ended April 30, 2017 and 2016 was $1.7 million and $3.5 million.
