NJ Teacher 403b Options in 403(b) Forum Posted January 27 · Report reply 1 hour ago, tony said: zkrw It's definitely hit or miss. I'm just glad I figured out the difference between the two Lincolns. Lincoln Financial and Lincoln Investments. Why would two investment companies want to share the same name and cause confusion and possibly give away their business to a similar sounding company. I'm not sure how much they compete. LF is insurance and annuities, LI is custodial accounts, although that may be only in the K-12 403b world.
