Adoption of ASC 606, Revenue from Contract with Customers (Topic 606)

We adopted Topic 606 on January 1, 2018, using the modified retrospective method with no impact on our financial statements. The cumulative effect of initially adopting Topic 606 guidance had no impact on the opening balance of retained earnings as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606 revenue standard, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Topic 605.

Nature of goods and services

The following is a description of principal activities from which we generate our revenue:

Broadcast Advertising Revenue

Our primary source of revenue is from the sale of advertising for broadcast on our stations. We recognize revenue from the sale of advertising as performance obligations are satisfied upon airing of the advertising; therefore, revenue is recognized at a point in time when each advertising spot is transmitted. Agency commissions are calculated based on a stated percentage applied to gross billing revenue for our advertising inventory placed by agency and are reported as a reduction of advertising revenue.

Digital Advertising Revenue

We recognize revenue from our digital initiatives across multiple platforms such as targeted digital advertising, online promotions, advertising on our websites, mobile messaging, email marketing and other e-commerce. Revenue is recorded when each specific performance obligation in the digital advertising campaign takes place, typically within a one month period.

Other Revenue

Other revenue includes revenue from concerts, promotional events, tower rent and other miscellaneous items. Revenue is generally recognized when the event is completed, as the promotional events are completed or as each performance obligation is satisfied.

Contract Liabilities

Payments from our advertisers are generally due within 30 days although certain advertisers are required to pay in advance. When an advertiser pays for the services in advance of the performance obligations these prepayments are recorded as contract liabilities. Typical contract liabilities relate to prepayments for advertising spots not yet run; prepayments from sponsors for events that have not yet been held; and gift cards sold on our websites used to finance a broadcast advertising campaign. Generally all contract liabilities are expected to be recognized within one year and are included in accounts payable in the Company’s Condensed Consolidated Financial Statements and are immaterial.

Transaction Price Allocated to the Remaining Performance Obligations

As the majority of our contracts are one year or less, we have utilized the optional exemption under ASC 606‑10‑50‑14 and will not disclose information about the remaining performance obligations for contracts which have original expected durations of one year or less.
