On December 31, 2017, the Company adopted the updated guidance on revenue from contracts with customers using the modified retrospective method applied to those contracts which were not completed as of December 31, 2017. Results for reporting periods beginning after December 31, 2017 are presented under the updated guidance, while prior period amounts are not adjusted and continue to be reported in accordance with the Company’s historical revenue accounting.

The Company recorded a net increase to opening retained earnings of $2,145 as of December 31, 2017 due to the cumulative impact of adopting the updated guidance, inclusive of a $3,501 decrease to deferred revenue, a decrease of $568 to prepaid expenses and other current assets and an increase to the deferred income tax liability of $788.

Revenues are recognized when control of the promised services or goods is transferred to the Company’s customers, in an amount that reflects the consideration it expects to be entitled to in exchange for those services or goods. See Note 2 for further information on the Company’s revenue recognition policies.

For Service Revenues, the Company typically collects payment in advance of providing services. Any amounts collected in advance of services being provided are recorded in deferred revenue. In the case where amounts are not collected, but the service has been provided and the revenue has been recognized, the amounts are recorded in accounts receivable. The opening and ending balances of the Company’s deferred revenues are as follows:

	Deferred		Deferred
	Revenue		Revenue-Long Term
Balance as of December 29, 2018	$	53,501	$	961
Net increase (decrease) during the period		7,112		(907	)
Balance as of December 28, 2019	$	60,613	$	54

Revenue recognized from amounts included in current deferred revenue as of December 29, 2018 was $53,479 for the fiscal year ended December 28, 2019. The Company’s long-term deferred revenue, which is included in other liabilities on the Company’s consolidated balance sheet, had a balance of $54 and $961 at December 28, 2019 and December 29, 2018, respectively, for revenue that will not be recognized during the next fiscal year and is generally related to upfront payments received as an inducement for entering into certain sales-based royalty agreements with third party licensees. This revenue is amortized on a straight-line basis over the term of the applicable agreement.

The Company elected to apply the updated guidance only to contracts that were not completed as of December 31, 2017, the date of adoption. The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. The Company expenses sales commissions when incurred (amortization period would have been one year or less) and these expenses are recorded within selling, general and administrative expenses. The Company treats shipping and handling fees as fulfillment costs and not as a separate performance obligation, and as a result, any fees received from customers are included in the transaction price allocated to the performance obligation of providing goods with a corresponding amount accrued within cost of product sales and other for amounts paid to applicable carriers. Sales tax, value-added tax, and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue.
