Fair Value of Debt

The fair value of Anixter's debt instruments is measured using observable market information which would be considered Level 2 in the fair value hierarchy described in accounting guidance on fair value measurements. The Company's fixed-rate debt consists of Senior notes due 2025, Senior notes due 2023 and Senior notes due 2021.

At March 29, 2019, the Company's total carrying value and estimated fair value of debt outstanding was $1,368.3 million and $1,416.4 million, respectively. This compares to a carrying value and estimated fair value of debt outstanding at December 28, 2018 of $1,252.7 million and $1,261.7 million, respectively. The increase in the carrying value and estimated fair value is primarily due to higher outstanding borrowings under Anixter's revolving lines of credit.
