TCP2 401(k) Retirement Plan

A tax-deferred retirement plan to help provide financial stability for retirees.

401(k) retirement plan for TCP2 participants

Fidelity Investments is the designated administrator and record keeper of the TCP2 401(k) retirement plan, and provides all account services. Enrollment, changes, account balances, loans, rollovers, and any other actions related to your 401(k) are handled through Fidelity.

The tax-deferred 401(k) plan is administered under the guidelines of Section 401(k) of the Internal Revenue Code.


The 401(k) Retirement Plan allows for an open brokerage window, allowing participants to select mutual funds that are not in the plan’s preselected core line up.

Funds outside of the core line up are not reviewed or monitored by a Plan fiduciary for suitability of participant accounts, so participants should carefully consider the risks before using the open brokerage window.
