Deferred Revenue, Income and Remaining Performance Obligations

NOTE 10. DEFERRED REVENUE, INCOME AND REMAINING PERFORMANCE OBLIGATIONS

Deferred revenue consists of amounts received for products or services not yet delivered or earned. Deferred income consists of amounts received for commitments not yet fulfilled. If we anticipate that the revenue or income will not be earned within the following twelve months, the amount is reported as long-term deferred income. A summary of the balances as of December 31 follows (in thousands):

	2018		2017
Products and services not yet delivered	$	217	$	71
Arizona Commerce Authority grant	—		1,000
Deferred revenue and income	$	217	$	1,071

As described in Note 9, License Agreements and Grants, we received $1.0 million in milestone payments from the Authority pursuant to the Grant Agreement. During the year ended December 31, 2018, the “claw-back” provisions expired and the $1.0 million was recognized as an offset to expense.

We recognized $26,000 of revenues during the year ended December 31, 2018 that were included in the contract liabilities balances at the beginning of the period. No material amount of revenue recognized during the current period was from performance obligations satisfied in prior periods.

Transaction Price Allocated to Remaining Performance Obligations

As of December 31, 2018, $1.7 million of revenue is expected to be recognized from remaining performance obligations. This balance primarily relates to executed service contracts that begin as warranty periods expire. These service contracts typically provide for four-year terms and revenue is recognized on a straight-line basis. The balance also includes product shipments for reagent rental, sales-type lease agreements. The agreements have between two and four year terms and revenue is recognized as product is shipped, typically in a straight-line pattern.

The Company elects not to disclose the value of unsatisfied performance obligations for (i) contracts with an expected length of less than one year and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.
