REVENUE

We generate revenues principally from subscriptions and advertising. Subscription revenues consist of revenues from subscriptions to our print and digital products (which include our news product, as well as our Crossword and Cooking products) and single-copy and bulk sales of our print products. Subscription revenues are based on both the number of copies of the printed newspaper sold and digital-only subscriptions, and the rates charged to the respective customers.

Advertising revenues are derived from the sale of our advertising products and services on our print and digital platforms. These revenues are primarily determined by the volume, rate and mix of advertisements. Display advertising revenue is principally from advertisers promoting products, services or brands. Display advertising also includes branded content on The Times’s platforms. Other advertising primarily represents, for our print products, classified advertising revenue. Digital other advertising revenue primarily includes creative services fees; advertising revenue from our podcasts; and advertising revenue generated by Wirecutter, our product review and recommendation website.

Other revenues primarily consist of revenues from licensing, commercial printing, building rental revenue, affiliate referrals (revenue generated by offering direct links to merchants in exchange for a portion of the sale price), NYT Live (our live events business) and retail commerce.

Performance Obligations

We allocate the transaction price of our digital archive licensing contracts among the performance obligations, (i) the delivery of archival content and (ii) the delivery of updated content, based on the Company’s estimate of the standalone selling price of each of the performance obligations, as they are currently not sold separately.

As of March 31, 2019, the aggregate amount of transaction price allocated to the remaining performance obligations (which represents the delivery of updated content to be delivered under our digital archive licensing contracts) was approximately $91 million. The Company will recognize this revenue as control of the performance obligation is transferred to the customer. We expect that approximately $15 million, $19 million and $57 million, will be recognized in the remainder of 2019, 2020, and thereafter, respectively.

Contract Assets

As of March 31, 2019, and December 30, 2018, the Company had $4.3 million and $2.5 million, respectively, in contract assets recorded in Other current assets in the Condensed Consolidated Balance Sheets related to the archival content of our digital archiving licensing revenue. The contract asset is reclassified to Accounts receivable when the customer is invoiced based on the contractual billing schedule. The increase in the contract assets balance of $1.8 million for the quarter ended March 31, 2019, is primarily driven by new contract assets of $2.0 million offset by $0.2 million of consideration that was reclassified to Accounts receivable when invoiced based on the contractual billing schedules for the period ended March 31, 2019.
