The Company holds both Agency and non-Agency available-for sale, or AFS, investment securities which are carried at fair value on the condensed consolidated balance sheets. The following table presents the Company’s AFS investment securities by collateral type as of March 31, 2023 and December 31, 2022:

Non-Agency 127,280  125,158 
Total available-for-sale securities $ 8,960,820  $ 7,778,734 

At March 31, 2023 and December 31, 2022, the Company pledged AFS securities with a carrying value of $9.0 billion and $7.4 billion, respectively, as collateral for repurchase agreements. See Note 11 - Repurchase Agreements.
At March 31, 2023 and December 31, 2022, the Company did not have any securities purchased from and financed with the same counterparty that did not meet the conditions of ASC 860, Transfers and Servicing, to be considered linked transactions and, therefore, classified as derivatives.
The Company is not required to consolidate VIEs for which it has concluded it does not have both the power to direct the activities of the VIEs that most significantly impact the entities’ performance, and the obligation to absorb losses or the right to receive benefits of the entities that could be significant. The Company’s investments in these unconsolidated VIEs include all non-Agency securities, which are classified within available-for-sale securities, at fair value on the condensed consolidated balance sheets. As of March 31, 2023 and December 31, 2022, the carrying value, which also represents the maximum exposure to loss, of all non-Agency securities in unconsolidated VIEs was $127.3 million and $125.2 million, respectively.
The following tables present the amortized cost and carrying value of AFS securities by collateral type as of March 31, 2023 and December 31, 2022:

Measurement of Allowances for Credit Losses on AFS Securities

The following table presents the changes for the three months ended March 31, 2023 and 2022 in the allowance for credit losses on Agency and non-Agency AFS securities:
