## BOND LADDER FUNDAMENTALS

### What Is a Bond Ladder?

```
BOND LADDER EXPLAINED
══════════════════════════════════════════════════════════════

DEFINITION:
A portfolio of bonds with staggered maturity dates,
creating regular income and reinvestment opportunities.

EXAMPLE: 10-YEAR LADDER WITH $100,000
─────────────────────────────────────────────────────────────
Year    Maturity    Investment   Yield     Annual Income
─────────────────────────────────────────────────────────────
1       2025        $10,000      4.5%      $450
2       2026        $10,000      4.6%      $460
3       2027        $10,000      4.7%      $470
4       2028        $10,000      4.8%      $480
5       2029        $10,000      4.9%      $490
6       2030        $10,000      5.0%      $500
7       2031        $10,000      5.1%      $510
8       2032        $10,000      5.2%      $520
9       2033        $10,000      5.3%      $530
10      2034        $10,000      5.4%      $540
─────────────────────────────────────────────────────────────
TOTAL:              $100,000     4.95%     $4,950/year

Each year, the shortest bond matures → Reinvest at 10-year rate
```

### Why Use a Bond Ladder?

```
BOND LADDER BENEFITS
══════════════════════════════════════════════════════════════

BENEFIT 1: REDUCED INTEREST RATE RISK
─────────────────────────────────────────────────────────────
If rates rise: Maturing bonds reinvest at higher rates
If rates fall: Existing longer bonds lock in higher rates
You get "average" rate, avoiding timing risk

BENEFIT 2: PREDICTABLE INCOME
─────────────────────────────────────────────────────────────
Known payment schedule for planning
Great for retirement income needs
Less volatility than bond funds

BENEFIT 3: LIQUIDITY THROUGH MATURITIES
─────────────────────────────────────────────────────────────
Regular maturity dates = regular cash availability
No need to sell at potentially bad prices
Built-in access to principal

BENEFIT 4: PRINCIPAL PRESERVATION
─────────────────────────────────────────────────────────────
Hold to maturity = get face value back (assuming no default)
No interest rate losses if you don't sell early
Unlike bond funds that fluctuate
```

## BOND TYPE SELECTION

### Treasury Bonds

```
TREASURY BONDS
══════════════════════════════════════════════════════════════

WHAT THEY ARE:
Bonds issued by US government
Backed by "full faith and credit"
Considered risk-free for default

TYPES:
─────────────────────────────────────────────────────────────
Treasury Bills (T-Bills): <1 year maturity
Treasury Notes: 2-10 year maturity
Treasury Bonds: 20-30 year maturity
TIPS: Inflation-protected

TAX TREATMENT:
─────────────────────────────────────────────────────────────
Federal: Taxable
State/Local: EXEMPT
Great for high-state-tax residents

CURRENT YIELDS (example):
─────────────────────────────────────────────────────────────
1-year: 4.8%
2-year: 4.5%
5-year: 4.3%
10-year: 4.5%
30-year: 4.7%

WHERE TO BUY:
─────────────────────────────────────────────────────────────
TreasuryDirect.gov (direct from Treasury)
Brokerages (Fidelity, Schwab, Vanguard)
No commission at TreasuryDirect
```

### Municipal Bonds

```
MUNICIPAL BONDS
══════════════════════════════════════════════════════════════

WHAT THEY ARE:
Bonds issued by state/local governments
Fund infrastructure, schools, hospitals

TYPES:
─────────────────────────────────────────────────────────────
General Obligation (GO): Backed by taxing power
Revenue Bonds: Backed by specific project revenue

TAX TREATMENT:
─────────────────────────────────────────────────────────────
Federal: Usually EXEMPT
State: Often EXEMPT if in-state bond
Great for high-tax-bracket investors

TAX-EQUIVALENT YIELD:
─────────────────────────────────────────────────────────────
Formula: Muni Yield / (1 - Tax Rate)

Example:
Muni yields 3.5%
Your tax bracket: 35%
Tax-equivalent: 3.5% / (1 - 0.35) = 5.38%

This means 3.5% muni = 5.38% taxable bond after taxes

CREDIT RISK:
─────────────────────────────────────────────────────────────
Munis CAN default (rare but happens)
Check credit ratings (AAA best)
Diversify across issuers
```

### Corporate Bonds

```
CORPORATE BONDS
══════════════════════════════════════════════════════════════

WHAT THEY ARE:
Bonds issued by corporations
Higher yield but higher risk than Treasuries

CREDIT RATINGS:
─────────────────────────────────────────────────────────────
Investment Grade: AAA, AA, A, BBB
High Yield (Junk): BB, B, CCC, CC, C, D

For ladders, stick to investment grade.

TAX TREATMENT:
─────────────────────────────────────────────────────────────
Federal: Taxable
State: Taxable
Fully taxable at ordinary income rates

YIELD SPREAD OVER TREASURIES:
─────────────────────────────────────────────────────────────
AAA Corporates: +0.3-0.5%
A-rated: +0.7-1.0%
BBB-rated: +1.2-1.8%

Higher spread = more credit risk

WHEN TO USE CORPORATE:
─────────────────────────────────────────────────────────────
• In tax-advantaged accounts (IRA, 401k)
• When extra yield justifies credit risk
• Diversify issuers to reduce default risk
```

## BUILDING YOUR LADDER

### Step-by-Step Construction

```
BOND LADDER CONSTRUCTION
══════════════════════════════════════════════════════════════

STEP 1: DETERMINE LADDER PARAMETERS
─────────────────────────────────────────────────────────────
• Total investment: $_______
• Ladder length: _____ years
• Bond type: Treasury / Muni / Corporate
• Rung spacing: Annual / Semi-annual

STEP 2: DIVIDE INTO EQUAL RUNGS
─────────────────────────────────────────────────────────────
$100,000 ladder / 10 rungs = $10,000 per rung

STEP 3: SELECT BONDS FOR EACH RUNG
─────────────────────────────────────────────────────────────
For each maturity year, find bonds with:
• Appropriate maturity date
• Acceptable credit quality
• Competitive yield

STEP 4: PURCHASE BONDS
─────────────────────────────────────────────────────────────
Buy at brokerage or TreasuryDirect
May need to buy at premium/discount to par
Aim for similar amounts in each rung

STEP 5: SET UP REINVESTMENT PLAN
─────────────────────────────────────────────────────────────
As each bond matures:
Option A: Reinvest at longest rung (10 years)
Option B: Spend the principal (for income needs)
Option C: Shorten ladder as you age
```

### Example: $500,000 Treasury Ladder

```
$500,000 TREASURY LADDER (10-YEAR)
══════════════════════════════════════════════════════════════

Rung   Maturity    Principal    Yield     Annual Interest
─────────────────────────────────────────────────────────────
1      2025        $50,000      4.5%      $2,250
2      2026        $50,000      4.5%      $2,250
3      2027        $50,000      4.5%      $2,250
4      2028        $50,000      4.5%      $2,250
5      2029        $50,000      4.6%      $2,300
6      2030        $50,000      4.6%      $2,300
7      2031        $50,000      4.6%      $2,300
8      2032        $50,000      4.7%      $2,350
9      2033        $50,000      4.7%      $2,350
10     2034        $50,000      4.8%      $2,400
─────────────────────────────────────────────────────────────
TOTAL              $500,000     4.6%      $23,000/year

$23,000 annual income = $1,917/month
Plus $50,000 maturing each year for spending or reinvestment
```

## REINVESTMENT STRATEGY

```
MANAGING YOUR LADDER OVER TIME
══════════════════════════════════════════════════════════════

ROLLING LADDER (maintain duration):
─────────────────────────────────────────────────────────────
Each year: Shortest bond matures
Action: Buy new 10-year bond

Before:
Rungs at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 years

After Year 1:
Rung 1 matures, reinvest at 10 years
New rungs: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 years

Ladder continues indefinitely.

SHORTENING LADDER (for spending):
─────────────────────────────────────────────────────────────
Each year: Shortest bond matures
Action: Spend the principal (don't reinvest)

After 10 years: All bonds matured, all principal spent
Use this for known future expenses (retirement income)

ADAPTING TO RATE CHANGES:
─────────────────────────────────────────────────────────────
If rates rise: Happy to reinvest at higher rates
If rates fall: Existing bonds lock in good rates
Either way, ladder reduces timing risk
```

## TAX-EFFICIENT PLACEMENT

```
WHERE TO HOLD WHICH BONDS
══════════════════════════════════════════════════════════════

TAXABLE ACCOUNTS:
─────────────────────────────────────────────────────────────
Best: Municipal bonds (tax-exempt)
OK: Treasury bonds (state tax exempt)
Avoid: Corporate bonds (fully taxable)

TAX-ADVANTAGED ACCOUNTS (IRA, 401k):
─────────────────────────────────────────────────────────────
Best: Corporate bonds (highest yield, tax doesn't matter)
OK: Treasury bonds
Avoid: Municipal bonds (waste the tax exemption)

REASONING:
─────────────────────────────────────────────────────────────
Put fully taxable income in tax-sheltered accounts
Put tax-advantaged income in taxable accounts
Maximize after-tax yield
```

## BEST PRACTICES

### Do's ✅
1. **Match ladder to time horizon** - Longer for longer needs
2. **Stick to investment grade** - Don't chase yield with risk
3. **Diversify issuers** - Especially with corporates
4. **Hold to maturity** - Avoid selling early
5. **Consider tax efficiency** - Right bonds in right accounts
6. **Reinvest systematically** - Maintain the ladder

### Don'ts ❌
1. **Don't ignore credit risk** - Corporates can default
2. **Don't chase high yields** - Higher yield = higher risk
3. **Don't sell early** - Takes losses and defeats purpose
4. **Don't put munis in IRA** - Wastes tax exemption
5. **Don't over-concentrate** - Spread across issuers
6. **Don't forget inflation** - Consider TIPS for portion
