Contract Liabilities

Contract liabilities consist of the Company’s obligation to transfer goods or services to a customer for which the Company has received consideration or the amount is due from the customer. As of October 31, 2020, contract liability balances are comprised of variable consideration estimated based on a portfolio basis using the expected value methodology based on analysis of historical data, current economic conditions, and contractual terms. Variable consideration estimates consist of the estimated returns, price discounts, price protection, rebates, and stock rotation programs. As of the end of a reporting period, some of the performance obligations associated with contracts will have been unsatisfied or only partially satisfied. In accordance with the practical expedients available in the guidance, the Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less. Contract liabilities are included in accrued liabilities in the unaudited condensed consolidated balance sheets.

The opening balance of contract liabilities at the beginning of the first quarter of fiscal year 2021 was $111.5 million. During the nine months ended October 31, 2020, contract liabilities increased by $617.7 million associated with variable consideration estimates, offset by $596.3 million decrease in such reserves primarily due to credit memos issued to customers. The ending balance of contract liabilities as of the third quarter of fiscal year 2021 was $132.9 million. The amount of revenue recognized during the nine months ended October 31, 2020 that was included in the contract liabilities balance at February 1, 2020 was not material.
Sales Commissions

The Company has elected to apply the practical expedient to expense commissions when incurred as the amortization period is typically one year or less. These costs are recorded in selling, general and administrative expenses in the unaudited condensed consolidated statements of operations.
