During the three months ended March 28, 2020, the Company completed a business combination. Based on the Company’s preliminary purchase price allocation, approximately $9.5 million of the purchase price has been assigned to deferred revenue. The Company is still gathering additional information to finalize this preliminary estimate and expects to finalize the purchase price allocation as soon as practicable, but no later than one year from the acquisition date.

Expected revenue from remaining contractual performance obligations (Unrecognized Contract Revenue) includes deferred revenue, as well as other amounts that will be invoiced and recognized as revenue in future periods, when the Company completes its performance obligations. While Unrecognized Contract Revenue is similar in concept to backlog, Unrecognized Contract Revenue excludes revenue allocable to monitoring-related equipment that is effectively leased to customers under deferred equipment agreements and other contractual obligations for which neither party has performed.

The following table summarizes the Company’s estimated Unrecognized Contract Revenue as of March 28, 2020 and the future periods within which the Company expects to recognize such revenue.



	Expected Future Revenue By Period (in thousands)
	Less than 1 Year		Between 1-3 Years		Between 3-5 Years		More than 5 Years		Total
Unrecognized contract revenue	$	212,273	$	344,630	$	173,384	$	46,381	$	776,668

The estimated timing of this revenue is based, in part, on management’s estimates and assumptions about when its performance obligations will be completed. As a result, the actual timing of this revenue in future periods may vary, possibly materially, from those reflected in this table.
