) access to core laboratories became essential. Once the research institutions recognized the potential cost savings of provisioning state-of-the-art instrumentation and services in a centralized way, multiple shared facilities were established, prompting discussions about the best ways to administer and finance them. The high-value and difficult-to-operate equipment typically used in a core setting in the beginning of the 21st century included NMR spectrometers,

(IDC). The second option is convenient, as the institution's administration retains full control, and, since the true facility costs are offset through the IDC, the direct costs to the researchers can be decreased, thus attracting investigators from outside the institution as well and lowering the institution's overall financial burden of maintaining a core facility. As a result, in the United States, the IDC for government grants in the 2020s were occasionally as high as 95% of the amount, with the average rate of 30%, and 60% not uncommon.
