Comparison of Financial Condition at December 31, 2020 and December 31, 2019
Cash and Cash Equivalents. At December 31, 2020 and 2019, cash and cash equivalents totaled $9.7 million and $18.8 million, respectively. Cash and cash equivalents decreased due primarily to net purchases in investments and treasury stock, partially offset from funds provided by increases in deposits and operating activities. We have focused on investing excess liquidity in higher yielding loans and investment securities in an effort to increase net interest income.
Loans. Our primary lending activity is the origination of loans secured by real estate. We originate one-to-four family residential loans, multi-family residential loans, commercial real estate loans and construction loans. To a lesser extent, we originate commercial business loans and consumer loans. In August 2016, we opened a loan production office in New Albany, Indiana as part of our effort to increase our business lending and diversify the loan portfolio. Net loans receivable decreased $10.0 million, or 8.1%, to $113.3 million at December 31, 2020 from $123.3 million at December 31, 2019. The decrease in net loans receivable was due primarily to decreases in one-to-four family residential loans, commercial real estate loans and commercial real estate construction loans.
One-to-four family residential loans comprise the largest segment of our loan portfolio. At December 31, 2020, these loans totaled $66.1 million, or 57.6% of total loans, compared to $71.6 million, or 57.4% of total loans, at December 31, 2019. The Bank originates both fixed- and adjustable-rate one-to-four family residential loans. We have recently increased our efforts to originate adjustable-rate one-to-four family residential loans and originated $9.3 million and $7.5 million of adjustable-rate loans in 2020 and 2019, respectively. Management intends to continue its focus on offering adjustable-rate mortgage loans at attractive rates.
Multi-family residential mortgage loans totaled $9.0 million, or 7.8% of total loans, at December 31, 2020 compared to $9.3 million, or 7.4% of total loans at December 31, 2019. Despite the decrease in the year-over-year balance, we continue our effort to originate this type of loan.
Commercial real estate loans totaled $30.2 million, or 26.3% of total loans, at December 31, 2020 compared to $32.3 million, or 25.9% of total loans, at December 31, 2019. During 2020 and 2019, we originated $5.8 million and $5.7 million, respectively, of commercial real estate loans with an emphasis on adjustable-rate loans.
Our construction loan portfolio consists of residential and commercial construction loans. Construction loans totaled $2.9 million, or 2.5% of total loans (excluding unfunded construction loan commitments of $2.9 million), at December 31, 2020, compared to $3.2 million, or 2.6% of total loans (excluding unfunded construction loan commitments of $1.8 million), at December 31, 2019. Commercial construction loan originations decreased to $850,000 during 2020 from $2.7 million in 2019.
Commercial business loans totaled $5.2 million, or 4.5% of total loans at December 31, 2020, compared to $6.5 million, or 5.2% of total loans, at December 31, 2019. During 2020 and 2019, we originated commercial business loans of $3.3 million and $2.3 million, respectively.
Consumer loans totaled $1.4 million, or 1.3% of total loans at December 31, 2020, compared to $1.9 million, or 1.5% of total loans, at December 31, 2019. Originations of consumer loans were $603,000 in 2020 compared to $1.0 million in 2019.
Securities Available for Sale. Our available for sale securities portfolio consists primarily of U.S. government agency debt securities, including mortgage-backed securities and collateralized mortgage obligations, and municipal obligations. Available for sale securities increased by $46.0 million, or 78.8%, to $104.5 million at December 31, 2020 from $58.4 million at December 31, 2019. Investment securities increased due primarily to the purchase of $57.4 million of available for sale securities and a $2.6 million increase in the unrealized gain on available for sale securities which were partially offset by the $4.5 million sale of available for sale securities and $9.3 million from scheduled principal payments and maturities of mortgage-backed and tax-exempt securities. During 2020, we continued our strategy to increase our investment in municipal obligations as a component of our available for sale securities portfolio due to their higher tax-equivalent yield. At December 31, 2020, our investment in municipal obligations was $66.4 million compared to $37.9 million at December 31, 2019.
