As a result of the current decline in the Europe market and management’s efforts to focus on resources within the markets that provide the Company with the strongest growth opportunity, in 2019 the Company made the determination that the remaining investment in its Hackett Institute Enterprise Analytics Program was impaired. The remaining investment as of December 27, 2019 was $1.2 million.

As a result of the emergence of strict cyber-security requirements, the release of the General Data Protection Regulation (“GDPR”) in Europe, and well publicized data breaches that have occurred with U.S. companies throughout 2018, clients have made significant procedural and process changes that have made the implementation of the Company’s Hackett Performance Exchange data extraction offering extremely difficult. Clients prefer to input or upload spreadsheets to our data collection systems rather than allow for direct data extraction. Therefore in 2018, the Company determined that the remaining investment of $5.9 million was impaired. In addition, as part of the discontinuance of our REL Working Capital practice, the Company decided to eliminate the Working Capital Course that was developed.
