Financial Instruments and Fair Value Measurement |
Financial Instruments and Fair Value Measurement | 5.Financial Instruments and Fair Value Measurement The estimated fair value of our available-for-sale securities, reflected on our Consolidated Condensed Balance Sheets as Investments, is based on Level 1 inputs. The following is a summary of available-for-sale securities, which excludes assets held in a Non-qualified Supplemental Savings Plan:
|  |  |  |  | Gross |  | Gross |  | Estimated |
|  |  |  |  | Unrealized |  | Unrealized |  | Fair |
|  | Cost |  | Gains |  | Losses |  | Value |
|  | (in thousands) |
Equity Securities: |  |  |  |  |  |  |  |  |  |  |  |  |
March 31, 2018 |  | $ | 38,473 |  | $ | 26,572 |  | $ | (6,664) |  | $ | 58,381 |
September 30, 2017 |  | $ | 38,473 |  | $ | 31,700 |  | $ | — |  | $ | 70,173 |
On an ongoing basis we evaluate the marketable equity securities to determine if any decline in fair value below cost is other-than-temporary. If a decline in fair value below cost is determined to be other-than-temporary, an impairment charge is recorded and a new cost basis established. We review several factors to determine whether a loss is other-than-temporary. These factors include, but are not limited to, (i) the length of time a security is in an unrealized loss position, (ii) the extent to which fair value is less than cost, (iii) the financial condition and near-term prospects of the issuer and (iv) our intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. When securities are sold, the cost of securities used in determining realized gains and losses is based on the average cost basis of the security sold. One of our securities declined to an unrealized loss position during the three months ended March 31, 2018. The security is in the international offshore drilling industry which is cyclical and only increased modestly in 2017 after several years of declines in the offshore drilling sector. Subsequent to March 31, 2018, the market price of the security increased to a value above cost. Considering the factors above including the limited time that the security was in an unrealized position and based on our ability and intent to hold these investments until the fair value recovers, impairment was not considered other-than-temporary at March 31, 2018. The assets held in the Non-qualified Supplemental Savings Plan are carried at fair value which totaled $15.0 million at March 31, 2018 and $13.9 million at September 30, 2017. The assets are comprised of mutual funds that are measured using Level 1 inputs. Short-term investments include securities classified as trading securities. Both realized and unrealized gains and losses on trading securities are included in other income (expense) in the Consolidated Condensed Statements of Operations. The securities are recorded at fair value. The majority of cash equivalents are invested in highly liquid money-market mutual funds invested primarily in direct or indirect obligations of the U.S. Government. The carrying amount of cash and cash equivalents approximates fair value due to the short maturity of those investments. Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. We use the fair value hierarchy established in ASC 820-10 to measure fair value to prioritize the inputs:
| · |  | Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.
| · |  | Level 2 — Observable inputs, other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets; quoted prices for similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.
| · |  | Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.
At March 31, 2018, our financial instruments utilizing Level 1 inputs include cash equivalents, equity securities with active markets and money market funds that are classified as restricted assets. The current portion of restricted amounts are included in prepaid expenses and other, and the noncurrent portion are included in other assets. For these items, quoted current market prices are readily available. At March 31, 2018, Level 2 inputs include certificates of deposit, U.S. Agency issued debt securities, municipal bonds and corporate bonds measured using broker quotations that utilize observable market inputs. Our financial instruments measured using Level 3 inputs consist of potential earnout payments associated with the acquisition of MOTIVE Drilling Technologies, Inc. in fiscal 2017. The valuation techniques used for determining the fair value of the potential earnout payments use a Monte Carlo simulation which evaluates numerous potential earnings and pay out scenarios. The following table summarizes our assets and liabilities measured at fair value presented in our Consolidated Condensed Balance Sheet as of March 31, 2018:
