RESTRICTED CASH AND INVESTMENTS |
NOTE 3: | RESTRICTED CASH AND INVESTMENTS
Restricted cash and investments consist principally of collateral that has been provided or pledged to insurance carriers for workers' compensation and state workers' compensation programs. Our insurance carriers and certain state workers' compensation programs require us to collateralize a portion of our workers' compensation obligation. The collateral typically takes the form of cash and cash equivalents and highly rated investment grade securities, primarily in U.S. Treasury Securities, U.S. Agency Debentures, U.S. Agency Mortgages, Corporate Securities and Municipal Securities. The majority of our collateral obligations are held in a trust ("Trust") at the Bank of New York Mellon. The following is a summary of restricted cash and investments (in millions):
| September 28, 2012 |  | December 30, 2011
Cash collateral held by insurance carriers | $ | 21.5 |  |  | $ | 21.3 |
Cash and cash equivalents held in Trust (1) | 21.7 |  |  | 19.2 |
Investments held in Trust | 80.0 |  |  | 78.0 |
Cash collateral backing letters of credit | 1.8 |  |  | 5.9 |
Other (2) | 7.1 |  |  | 6.1 |
Total restricted cash and investments | $ | 132.1 |  |  | $ | 130.5 |

The amortized cost and fair value by contractual maturity of our held-to-maturity investments are as follows (in millions):
| September 28, 2012
| Amortized Cost |  | Fair Value
Due in one year or less | $ | 11.3 |  |  | $ | 11.4 |
Due after one year through five years | 40.1 |  |  | 41.1 |
Due after five years through ten years | 28.6 |  |  | 29.4 |
| $ | 80.0 |  |  | $ | 81.9 |
Actual maturities may differ from contractual maturities because the issuers of certain debt securities have the right to call or prepay their obligations without penalty.
