*     HTM securities are shown on the balance sheet at amortized cost, net of allowance for credit losses of $174 thousand as of March 31, 2021.

The Company's HTM municipal securities consist largely of private issues of municipal debt. The large majority of the municipalities are located within the Midwest. The municipal debt investments are underwritten using specific guidelines with ongoing monitoring.

The Company's residential mortgage-backed and related securities portfolio consists entirely of government sponsored or government guaranteed securities. The Company has not invested in private mortgage-backed securities or pooled trust preferred securities.

Gross unrealized losses and fair value, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position as of March 31, 2021 and December 31, 2020, are summarized as follows:

At March 31, 2021, the investment portfolio included 644 securities. Of this number, 101 securities were in an unrealized loss position. The aggregate losses of these securities totaled approximately 0.4% of the total amortized cost of the portfolio. Of these 101 securities, there were eight securities that had an unrealized loss for twelve months or more. Asset-backed securities are comprised of collateralized loan obligations, which are debt securities backed by pools of senior secured commercial loans to a diverse group of companies across a broad spectrum of industries. At March 31, 2021, the Company only owned collateralized loan obligations that were AAA rated. All of the debt securities in unrealized loss positions are considered acceptable credit risks. Based upon an evaluation of the available evidence, including the recent changes in market rates, credit rating information and information obtained from regulatory filings, management believes the declines in fair value for these debt securities are temporary. In addition, the Company lacks the intent to sell these securities and it is not more-likely-than-not that the Company will be required to sell these debt securities before their anticipated recovery.  

On January 1, 2021, the Company adopted ASU 2016-13, which replaced the legacy GAAP other-than-temporary impairment (“OTTI”) model with a credit loss model. ASU 2016-13 requires an allowance on lifetime expected credit losses on held to maturity debt securities. The following table presents the activity in the allowance for credit losses for held to maturity securities by major security type for the three months ended March 31, 2021.

	Three Months Ended March 31, 2021
		Municipal securities		Other securities		Total
	(dollars in thousands)
Allowance for credit losses:
Beginning balance		$	—	$	—	$	—
Impact of adopting ASU 2016-13			182		1		183
Provision for credit loss expense			(9)		—		(9)
Balance, ending		$	173	$	1	$	174

The credit loss model under ASU 2016-13, applicable to AFS debt securities, requires the recognition of credit losses through an allowance account, but retains the concept from the OTTI model that credit losses are recognized once securities become impaired. See Note 1, “Summary of Significant  Accounting Policies” to the consolidated financial statement included in this Form 10-Q, for a discussion of the impact of the adoption of ASU 2016-13.

There were proceeds of $19.5 million from sales of securities, that resulted in no gains or losses, for the three months ended March 31, 2021. There were no sales of securities for the three months ended March 31, 2020.

The amortized cost and fair value of securities as of March 31, 2021 by contractual maturity are shown below. Expected maturities of residential mortgage-backed and related securities and asset-backed securities may differ from contractual maturities because the residential mortgages underlying the securities may be prepaid without any penalties. Therefore, these securities are not included in the maturity categories in the following table.

	Amortized Cost		Fair Value

Securities HTM:
Due in one year or less	$	3,592	$	3,611

Portions of the U.S. government sponsored agency securities, municipal securities and other securities contain call options, which, at the discretion of the issuer, terminate the security at par and at predetermined dates prior to the stated maturity. These callable securities are summarized as follows:

	Amortized Cost		Fair Value
	(dollars in thousands)
Securities HTM:
Municipal securities	$	246,515	$	255,969
Securities AFS:

As of March 31, 2021, the Company's municipal securities portfolios were comprised of general obligation bonds issued by 117 issuers with fair values totaling $117.6 million and revenue bonds issued by 192 issuers, primarily consisting of states, counties, towns, villages and school districts with fair values totaling $535.3 million. The Company also held investments in general obligation bonds in 21 states, including eight states in which the aggregate fair value exceeded $5.0 million, and in revenue bonds in 26 states, including 13 states in which the aggregate fair value exceeded $5.0 million.

As of December 31, 2020, the Company's municipal securities portfolios were comprised of general obligation bonds issued by 117 issuers with fair values totaling $116.7 million and revenue bonds issued by 191 issuers, primarily consisting of states, counties, towns, villages and school districts with fair values totaling $555.9 million. The Company also held investments in general obligation bonds in 21 states, including eight states in which the aggregate fair value exceeded $5.0 million, and in revenue bonds in 26 states, including 12 states in which the aggregate fair value exceeded $5.0 million.

Both general obligation and revenue bonds are diversified across many issuers. As of March 31, 2021 and as of December 31, 2020, the Company held revenue bonds of two issuers, located in Ohio, of which the aggregate book or market value

exceeded 5% of the Company’s stockholders’ equity. The issuer’s financial condition is strong and the source of repayment is diversified. The Company monitors the investments and concentration closely. Of the general obligation and revenue bonds in the Company's portfolio, the majority are unrated bonds that represent small, private issuances. All unrated bonds were underwritten according to loan underwriting standards and have an average loan risk rating of 2, indicating very high quality. Additionally, many of these bonds are funding essential municipal services such as water, sewer, education, and medical facilities.

The Company's municipal securities are owned by the four charters, whose investment policies set forth limits for various subcategories within the municipal securities portfolio. The investments of each charter are monitored individually, and as of March 31, 2021, all were within policy limitations approved by the board of directors. Policy limits are calculated as a percentage of each charter's total risk-based capital.

As of March 31, 2021, the Company's standard monitoring of its municipal securities portfolio had not uncovered any facts or circumstances resulting in significantly different credit ratings than those assigned by a nationally recognized statistical rating organization, or in the case of unrated bonds, the rating assigned using the credit underwriting standards.
