Understanding Thrift Savings Plan (TSP) Investment Funds

The Thrift Savings Plan (TSP) is a powerful retirement savings tool for federal employees and members of the uniformed services. Managed by the Federal Retirement Thrift Investment Board (FRTIB), the TSP offers participants a range of investment options designed to help them grow their retirement savings. Here, we’ll walk you through the fundamentals of TSP investment funds, providing key insights to help you make informed decisions about your financial future.

TSP Investment Funds Overview

The TSP currently features five core individual funds and a selection of Lifecycle (L) Funds that blend these core funds. Each fund aligns with specific investment goals and risk tolerance levels. Here’s an introduction to the TSP’s investment options:

Five Individual Funds

G Fund (Government Securities Investment Fund):

• Invests in government securities specifically issued for TSP participants.
• No risk to principal but subject to inflation risk.
• Ideal for conservative investors looking for stability.

F Fund (Fixed Income Investment Fund):

• Tracks the Bloomberg U.S. Aggregate Bond Index.
• Offers moderate risk with exposure to bond market fluctuations.
• Suitable for those seeking income and moderate growth potential.

C Fund (Common Stock Index Investment Fund):

• Mirrors the performance of the S&P 500 Index.
• Provides exposure to large U.S. companies.
• Higher risk but higher potential returns.

S Fund (Small Capitalization Stock Index Investment Fund):

• Tracks the Dow Jones U.S. Completion Total Stock Market Index.
• Invests in smaller U.S. companies not included in the S&P 500.
• Adds diversity and growth potential.

I Fund (International Stock Index Investment Fund):

• Tracks the MSCI ACWI IMI ex USA ex China ex Hong Kong Index.
• Invests in over 5,000 companies from 44 countries, including developed and emerging markets.
• Excludes U.S., China, and Hong Kong stocks.
• Offers broad global diversification with exposure to currency and international market risks.

Lifecycle (L) Funds

L Funds are diversified portfolios of the five individual funds, tailored to different target retirement dates. These funds gradually shift from more aggressive investments (higher allocation in stock funds) to conservative investments (greater emphasis on G and F funds) as the target date approaches.

Since September 15, 2015, an age-appropriate L Fund has been the default investment option for new TSP participants. This means that unless new enrollees specify otherwise, their contributions are automatically invested in the L Fund that most closely aligns with their projected retirement date

Key Features:

• Automatically reallocate quarterly.
• Designed for those who prefer a hands-off approach.
• Include options like L Income (for those using funds now) and target-date funds (e.g., L 2055, L 2070).

Why Diversification Matters

Diversification is a cornerstone of investment strategy, helping to reduce risk by spreading investments across various asset classes. In TSP, diversification is achieved through index funds that track broad segments of the market. This strategy balances risk and potential returns, ensuring that poor performance in one sector can be offset by gains in another.

Passive Management and Low Costs

TSP funds use a passive management approach, aiming to mirror market performance rather than beat it. This method reduces trading costs and management fees, making TSP one of the most cost-effective retirement savings plans available.

Making Investment Decisions

Participants can manage their TSP accounts through three primary actions:

1. Investment Elections: Direct where new contributions, rollovers, or loan repayments are allocated.
2. Fund Reallocations: Adjust the allocation of your existing account balance across funds.
3. Fund Transfers: Move money from specific funds to others within your account.

These tools allow you to tailor your investment strategy over time, whether you’re building wealth early in your career or seeking stability closer to retirement.

TSP’s Mutual Fund Window

For those looking for additional investment options, the TSP Mutual Fund Window provides access to nearly 5,000 mutual funds. However, it comes with extra fees and restrictions, including:

• A $10,000 minimum initial transfer from core funds.
• A maximum of 25% of your total TSP savings in the window.
• Additional fees, such as a $150 annual maintenance fee and $28.75 per trade.

This option is best suited for experienced investors seeking greater diversification beyond TSP’s core offerings.

Understanding Costs and Fees

The cost of managing the TSP is reflected in its expense ratios, built into the share prices of the funds. These low costs help maximize your investment growth over time. Additional fees may apply for loans, court orders, or the mutual fund window.

Resources for Participants

To make informed decisions, take advantage of the many resources available on TSP.gov:

• Fund Sheets: Detailed overviews of each individual and lifecycle fund.
• Historical Performance: Track fund performance and share prices over time.
• Webinars and Courses: Educational sessions covering all aspects of the TSP.
• TSP Mobile App: Manage your account on the go.

Key Takeaways

The TSP is a critical component of federal retirement planning, offering low-cost, diversified investment options. By understanding the individual and lifecycle funds, participants can build portfolios that align with their goals, risk tolerance, and time horizons. Whether you prefer to actively manage your investments or let the L Funds do the work for you, the TSP provides the flexibility to meet your needs.
