Number of distribution channels | Distribution_Channels | 2 |
Estimated selling price determination approach | Certain of the Company’s contracts have multiple performance obligations, as the promise to transfer individual goods or services is separately identifiable from other promises in the contracts and, therefore, is distinct. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation based on its relative standalone selling price. The stand-alone selling prices are determined based on the prices at which the Company separately sells these products. For items that are not sold separately, the Company estimates the stand-alone selling prices using the best estimated selling price approach. |
