(1) On March 1, 2024, we completed the acquisition of 100% of the shares Elpis2, Inc. (Elpis Squared), a privately held software and services company. The purchase resulted in the addition of intangible assets of $15.0 million including $12.5 million identified core-developed technology and $2.5 million of customer contracts and relationships. The core-developed technology and customer contract and relationships will be amortized over the weighted-average five-year and three-year useful lives, respectively, using the straight-line method. Refer to Note 5: Goodwill and Note 17: Business Combination for additional information.

Assumed intangible liabilities reflect the present value of the projected cash outflows for a then existing contract for which remaining costs were expected to exceed projected revenues.

Estimated future annual amortization is as follows:


Year Ending December 31,	Estimated Annual Amortization
In thousands
2024 (amount remaining at September 30, 2024)	$	4,566
2025	17,775
2026	13,726
2027	8,273
2028	2,681
Thereafter	948
