4. Fair Value Measurements

Fair value is the 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 on the measurement date. The fair value hierarchy contains three levels as follows:

Level 1—Inputs to the valuation based upon quoted prices (unadjusted) for identical assets or liabilities in active markets that are accessible as of the measurement date.

Level 2—Inputs to the valuation include quoted prices in either markets that are not active, or in active markets for similar assets or liabilities, inputs other than quoted prices that are observable, and inputs that are derived principally from or corroborated by observable market data.

Level 3—Inputs to the valuation that are unobservable inputs for the asset or liability.

The Company did not have any financial assets measured at fair value on a recurring basis at October 27, 2018 as the Company’s remaining auction rate securities were redeemed during the three months ended July 28, 2018 at par value. The following table provides a reconciliation between the beginning and ending balances of items measured at fair value on a recurring basis that used significant unobservable inputs (Level 3) (in thousands):

	Measurements Using
	Significant
	Unobservable Inputs
Description	(Level 3)
Balance at May 1, 2018	$	2,142
Transfers to Level 3		—
Total gains (realized or unrealized)
Included in earnings		—
Included in other comprehensive income		108
Settlements		(2,250)
Balance at October 27, 2018	$	—
The amount of total gains or (losses) for the period included in earnings attributable to the change in unrealized gains or losses relating to assets still held at October 27, 2018	$	—

The auction rate securities were valued using a discounted cash flow model. The analysis considered, among other items, the collateralization underlying the security investments, the creditworthiness of the counterparty, the timing of expected future cash flows and the estimated date upon which the security is expected to have a successful auction.
