FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS
 
The Company’s fair value measurements are based upon a three-level valuation hierarchy. These valuation techniques are based upon the transparency of inputs (observable and unobservable) to the valuation of an asset or liability as of the measurement date. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy:
 
 
Level 1 — Valuation is based on quoted prices for identical assets or liabilities in active markets;
 
 
Level 2 — Valuation is based on quoted prices for similar assets or liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for the full term of the financial instrument; and
 
 
Level 3 — Valuation is based upon other unobservable inputs that are significant to the fair value measurement.
 
Recurring Fair Value Measurements
 
The Company maintains a non-qualified deferred compensation plan which is offered to senior management and other key employees. The amount owed to participants is an unfunded and unsecured general obligation of the Company. Participants are offered various investment options with which to invest the amount owed to them, and the plan administrator maintains a record of the liability owed to participants by investment. To minimize the impact of the change in market value of this liability, the Company has elected to purchase a separate portfolio of investments through the plan administrator similar to those chosen by the participant.
 
The investments purchased by the Company include mutual funds, $2.4 million of which are classified as Level 1, and life-insurance contracts valued based on the performance of underlying mutual funds, $14.1 million of which are classified as Level 2.
 
Additionally, upon the Company’s acquisition of Supreme, the Company acquired a pool of investments made by a wholly owned captive insurance subsidiary. These investments are comprised of mutual funds, $4.9 million of which are classified as Level 1.
 
Estimated Fair Value of Debt
 
The estimated fair value of debt at June 30, 2018 consists primarily of the Senior Notes due 2025 and borrowings under the Term Loan Credit Agreement (see Note 6). The fair value of the Senior Notes due 2025, Term Loan Credit Agreement and the Revolving Credit Facility are based upon third party pricing sources, which generally do not represent daily market activity or represent data obtained from an exchange, and are classified as Level 2. The interest rates on the Company’s borrowings under the Revolving Credit Facility are adjusted regularly to reflect current market rates and thus carrying value approximates fair value for these borrowings. All other debt and capital lease obligations approximate their fair value as determined by discounted cash flows and are classified as Level 3.
