Retirement Benefits [Abstract] |
Employee Benefit Plan | Employee Benefit Plan: Effective January 1, 1998, NNN adopted a defined contribution retirement plan (the “Retirement Plan”) covering substantially all of the employees of NNN. The Retirement Plan permits participants to defer a portion of their compensation, as defined in the Retirement Plan, subject to limits established by the Code. NNN generally matches 60 percent of the first eight percent of a participant’s contributions. Additionally, NNN may make discretionary contributions. NNN’s contributions to the Retirement Plan for the years ended December 31, 2018, 2017 and 2016 totaled $516,000, $514,000 and $491,000, respectively.
