(2)	Performance obligations

Remaining (unsatisfied or partially unsatisfied) performance obligations represent future revenues not yet recorded for firm orders that have not yet been performed. Sony applies practical expedients to exclude certain information about the remaining performance obligations, primarily related to contracts with an expected original duration of less than one year, and sales-based or usage-based royalty revenue on licenses of intellectual property. The following table shows the summary of the transaction prices allocated to remaining performance obligations that are unsatisfied at March 31, 2020, of which more than half are expected to be recognized within one year and substantially all within three years.

Pictures — Media Networks		22,333
Music *2		44,971
Others		47,126

For Motion Pictures and Television Productions in the Pictures segment, Sony has included all contracts regardless of duration.

Amount included in the Music segment primarily consists of minimum royalty guarantees or fixed fees in contracts related to license revenue for ongoing access to an evolving library of content. These contracts also include the potential for sales-based or usage-based royalties to exceed the minimum guarantees, and these additional royalties are excluded from the amount above, of which substantially all are recognized as revenue within three years.

(3)	Contract costs

Contract costs are comprised as follows:


	Yen in millions
	March 31 , 2019		March 31, 2020
Incremental costs of obtaining a contract		6,581		7,464

Sony applies practical expedients to recognize the incremental costs of obtaining a contract as an expense if the amortization period of the asset that otherwise would have been recognized is one year or less. The amortization of 6,420 million yen was recognized during the fiscal year ended March 31, 2020. The incremental costs of obtaining a contract are primarily recognized in the EP&S segment for the internet-related service business and amortized to expense over the contract period.
