Maturities

The amortized cost and fair value of available-for-sale fixed maturity securities at September 30, 2021, by contractual maturity, are shown in the following tables. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Asset-backed securities, mortgage-backed securities and collateralized mortgage obligations may be subject to prepayment risk and are therefore not categorized by contractual maturity.

Maturities
	Available-For-Sale

Due in one year or less	$	55,041	$	55,699

Due after five years through 10 years	353,810		373,415

Funding Commitment

Pursuant to an agreement with one of our limited liability partnership investments, we are contractually committed through July 10, 2030 to make capital contributions upon request of the partnership. Our remaining potential contractual obligation was $2,636 at September 30, 2021.

In addition, the Company invested $25,000 in December 2019 in a limited liability partnership investment fund which is subject to a three-year lockup with a 60 day minimum notice, with four possible repurchase dates per year, after the three-year lockup period is met. The fair value of the investment at September 30, 2021 was $24,786 and there are no remaining capital contributions with this investment.

Unrealized Appreciation

A summary of the changes in net unrealized investment appreciation during the reporting period is as follows:

	Nine Months Ended September 30,
	2021		2020
Change in net unrealized investment appreciation
Available-for-sale fixed maturities	$	(32,779)	$	44,574
Income tax effect	6,886		(9,361)
Total change in net unrealized investment appreciation, net of tax	$	(25,893)	$	35,213

Credit Risk

An allowance for credit losses is recorded based on a number of factors including the current economic conditions, management's expectations of future economic conditions and performance indicators, such as market value vs. amortized cost, investment spreads widening or contracting, rating actions, payment and default history. The following table contains a rollforward of the allowance for credit losses for available-for-sale fixed maturity securities at September 30, 2021:

Rollforward of allowance for credit losses for available-for-sale fixed maturity securities:
	As of
	September 30, 2021
Beginning balance, January 1, 2021	$	5
Additions to the allowance for credit losses for which credit losses were not previously recorded	—
Recoveries of amounts previously written off	(5)
Ending balance, September 30, 2021	$	—

The following tables summarize our fixed maturity securities that were in an unrealized loss position reported on a consolidated basis at September 30, 2021 and December 31, 2020. The securities are presented by the length of time they have been continuously in an unrealized loss position. Non-credit related unrealized losses are recognized as a component of other comprehensive income and represent other market movements that are not credit related, for example interest rate changes. We have no intent to sell, and it is more likely than not that we will not be required to sell, these securities until the fair value recovers to at least equal our cost basis or the securities mature.

The unrealized losses on our investments in available-for-sale fixed maturities were the result of interest rate movements. We have no intent to sell, and it is more likely than not that we will not be required to sell, these securities until the fair value recovers to at least equal our cost basis or the securities mature.
