We primarily use two fonts (typefaces) as of January 2017:
Acumin Pro Condensed (light and bold) and Georgia. Acumin Pro Condensed is available free through TypeKit, which is part of the Adobe Creative Cloud suite.
Please discontinue use of MT Arial Condensed; it doesn't have a complete glyph set.
Refer to the Style Guide for design and usage guidance.
