Sales and Marketing
The company sells its products to customers throughout North America, Europe, and Asia. Sales are made through one of three channels: strategic account managers or, in some cases, regional sales managers, working directly with the company’s customers; regional sales managers working with independent sales representative organizations; or authorized distributors. Bel's strategic account managers are assigned to handle major accounts requiring global coordination.
Independent sales representatives and authorized distributors are overseen by the company's sales management personnel located throughout the world. As of December 31, 2024, the company had a sales and support staff of approximately 240 people that supported a network of sales representative organizations and non-exclusive distributors. The company has written agreements with all its sales representative organizations and most of its major distributors.
Sales support functions have also been established and located in the company’s international facilities to provide timely, efficient support for customers. This supplemental level of service, in addition to first-line sales support, enables the company to be more responsive to customers' needs on a global level. The company’s marketing capabilities include product management, which drives new product development, application engineering for technical support, and marketing communications.
Intellectual Property
The company has acquired or been granted a number of patents in the U.S., Europe, and Asia, and has additional patent applications pending relating to its products. The company’s U.S. design patents have a life of 14 years, and its U.S. utility patents have a life of 17 years from the date of issue or 20 years from the filing of patent applications. The company’s existing patents expire on various dates through July 2041.
The company utilizes registered trademarks in the U.S., Europe, and Asia to identify various products that it manufactures.
Research and Development (‘R&D’)
The company’s research and development expenses were $23.6 million for the year ended December 31, 2024.
Seasonality
In the PRC, the availability of labor is cyclical and is significantly affected by the migration of workers in relation to the annual Lunar New Year holiday. Each year following the Lunar New Year holiday, the company must assess the worker return rate and whether it is adequate to meet the needs of current demand from its customers. Accordingly, the company must continually recruit and train new workers to replace those lost to attrition each year, and to address peaks in demand that may occur from time to time. This temporary setback in production has historically resulted in the company’s first-quarter sales being the lowest sales quarter of the year (year ended December 2024).
History
