Note M—Derivatives and Fair Value Measurements

From time to time, we may use interest rate swaps or other instruments to manage our interest rate exposure and reduce the impact of future interest rate changes. These financial instruments are not used for trading or speculative purposes. We have designated our interest rate swap contracts as cash flow hedges of our future interest payments. As a result, the gains and losses on the swap contracts are reported as a component of other comprehensive income and are reclassified into interest expense as the related interest payments are made. As of  June 27, 2020, all of other comprehensive income was attributable to shareholders; none related to the non-controlling interest.  Outstanding instruments as of June 27, 2020, are as follows:

The following table summarizes the fair value and presentation in the Condensed Consolidated Balance Sheets for derivatives related to our interest swap agreements as of  June 27, 2020, and  September 28, 2019 (in thousands):

From time to time, we may purchase cotton option contracts to economically hedge the risk related to market fluctuations in the cost of cotton used in our operations. We do not receive hedge accounting treatment for these derivatives. As such, the realized and unrealized gains and losses associated with them are recorded within cost of goods sold on the Condensed Consolidated Statement of Operations. No such cotton contracts were outstanding at  June 27, 2020, or September 28, 2019.

ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Assets and liabilities measured at fair value are grouped in three levels. The levels prioritize the inputs used to measure the fair value of the assets or liabilities. These levels are:

The following financial liabilities are measured at fair value on a recurring basis (in thousands):

The fair value of the interest rate swap agreements was derived from a discounted cash flow analysis based on the terms of the contract and the forward interest rate curves adjusted for our credit risk, which fall in Level 2 of the fair value hierarchy. At June 27, 2020 and September 28, 2019, book value for fixed rate debt approximates fair value based on quoted market prices for the same or similar issues or on the current rates offered to us for debt of the same remaining maturities (a Level 2 fair value measurement).

The DTG2Go acquisition purchase price consisted of additional payments contingent on the combined business’s achievement of certain performance targets related to sales and earnings before interest, taxes, depreciation and amortization ("EBITDA") for the period from April 1, 2018, through September 29, 2018, as well as for our fiscal years 2019, 2020, 2021 and 2022. The valuation of the fair value of the contingent consideration is based upon inputs into the Monte Carlo model, including projected results, which then are discounted to a present value to derive the fair value. The fair value of the contingent consideration is sensitive to changes in our projected results and discount rates. At September 28, 2019, the fair value of contingent consideration was estimated at $8.9 million. During the nine-months ended June 27, 2020, $2.5 million was paid related to the 2019 period. As of June 27, 2020, we estimate the fair value of contingent consideration to be $6.8 million, a $0.4 million increase, excluding the $2.5 million payment, from September 28, 2019, resulting from changes in the projections and adjustments to the discount rate.

In August 2013, we acquired Salt Life, which included contingent consideration as part of the purchase price and which is payable in cash after the end of calendar year 2019 if financial performance targets involving the sale of Salt Life-branded products are met during the 2019 calendar year. During fiscal year 2020, it was determined that the calendar year 2019 performance targets were not achieved and, as a result, the $0.2 million accrual as of September 28, 2019, was reversed. At June 27, 2020, no amount was accrued for contingent consideration in relation to the acquisition of Salt Life.
