liquidity sources management has reviewed all primary and secondary sources of liquidity in preparation for any unforeseen funding needs due to the covid-19 pandemic and prioritized based on available capacity , term flexibility , and cost . -29- as of september 30 , 2020 , the company had adequate sources of liquidity ( excluding the company 's ability to participate in the paycheck protection program liquidity facility ) . capital strength the company 's capital ratios continue to exceed the highest required regulatory benchmark levels . as of september 30 , 2020 , common equity tier 1 capital ratio was 14.25 percent , tier 1 leverage ratio was 11.87 percent , tier 1 risk-based capital ratio was 14.25 percent and the total risk-based capital ratio was 17.85 percent . deferral requests as of september 30 , 2020 , the company had 43 covid-19 loan modification agreements with respect to $ 147.9 million representing 14.2 percent of loans outstanding . the covid-19 loan modifications do not classify as tdrs as they fall under the cares act section 4013 , and f urther details regarding these modifications are provided in the table below . at january 15 , 2020 , the company had 15 covid-19-related modified loan deferrals totaling $ 71.3 million or 7.1 % of total loans . of the remaining $ 71.3 million deferrals , approximately $ 37.3 million or 52.3 % of the deferrals are paying the contractual interest payments . for loans subject to the program , each borrower is required to resume making regularly scheduled loan payments at the end of the modification period and the deferred amounts will be moved to the end of the loan term . management anticipates this activity will continue beyond fiscal year 2020. replace_table_token_2_th -30- certain industries are widely expected to be particularly impacted by social distancing , quarantines , and the economic impact of the covid-19 pandemic , such as the following : replace_table_token_3_th allowance for loan losses the allowance for loan losses represents management 's estimate of probable loan losses inherent in the loan portfolio . determining the amount of the allowance for loan losses is considered a critical accounting estimate because it requires significant judgment and the use of estimates related to the amount and timing of expected future cash flows on impaired loans , estimated losses on pools of homogeneous loans based on historical loss experience , and consideration of current economic trends and conditions , all of which may be susceptible to significant change . the loan portfolio also represents the largest asset type on the company 's consolidated statements of financial condition . the evaluation of the adequacy of the allowance for loan losses includes , among other factors , an analysis of historical loss rates by loan category applied to current loan totals and qualitative factors . however , actual loan losses may be higher or lower than historical trends , which vary . actual losses on specified problem loans , which also are provided for in the evaluation , may vary from estimated loss percentages , which are established based upon a limited number of potential loss classifications . the allowance for loan losses is established through a provision for loan losses charged to expense . management believes that the current allowance for loan losses will be adequate to absorb loan losses on existing loans that may become uncollectible based on the evaluation of known and inherent risks in the loan portfolio . the evaluation takes into consideration such factors as changes in the nature and size of the portfolio , overall portfolio quality , and specific problem loans and current economic conditions which may affect our borrowers ' ability to pay . the evaluation also details historical losses by loan category and the resulting loan loss rates which are projected for current loan total amounts . loss estimates for specified problem loans are also detailed . in addition , the occ , as an integral part of its examination process , periodically reviews our allowance for loan losses . the occ may require us to make additional provisions for loan losses based upon information available at the time of the examination . all of the factors considered in the analysis of the adequacy of the allowance for loan losses may be subject to change . to the extent actual outcomes differ from management estimates , additional provisions for loan losses may be required that could materially adversely impact earnings in future periods . qualitative or environmental factors that may result in further adjustments to the quantitative analyses include items such as changes in lending policies and procedures , economic and business conditions , nature and volume of the portfolio , changes in delinquency , concentration of credit trends , and value of underlying collateral . the total net adjustments due to all qualitative factors increased the allowance for loan losses by approximately $ 9.2 million and $ 6.7 million at september 30 , 2020 and september 30 , 2019 , respectively . an unallocated component is maintained to cover uncertainties that could affect management 's estimate of probable losses . the unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio . other real estate owned assets acquired through foreclosure consist of oreo and financial assets acquired from debtors . oreo is carried at the lower of cost or fair value , less estimated selling costs . the fair value of oreo is determined using current -31- market appraisals obtained from approved independent appraisers , agreements of sale , and comparable market analysis from real estate brokers , where applicable . story_separator_special_tag -37- the increase on the sale of investments resulted from managing and optimizing normal portfolio activity , while the gain on sale of loans was a result of a strategic effort to originate and sell residential loans in the current low interest rate environment . other expense the following table presents the principal categories of other expense for each of the years in the two-year period ended september 30 , 2020. replace_table_token_8_th for the fiscal year ended september 30 , 2020 , total other expense increased $ 815,000 , or 4.7 percent , compared to the fiscal year ended september 30 , 2019. this increase primarily reflects a $ 348,000 increase in salaries and employee benefits , a $ 247,000 increase in the pennsylvania shares tax , and a $ 196,000 increase in professional fees . these increases were partially offset by a $ 104,000 decrease in oreo expense , net , and a $ 66,000 decrease in the federal deposit insurance premium . the increase in salaries and employee benefits during the fiscal year ended september 30 , 2020 reflects normal increases to salary and benefits and additional hires to support overall franchise growth . the increased pennsylvania shares tax was due to the bank not being subject to this tax until the second quarter of 2019. the increase in professional fees was due to higher legal and professional services expenses of $ 182,000 and $ 160,000 , respectively , partially offset by lower audit and accounting expenses of approximately $ 143,000. the decrease in oreo expense , net , was due to successfully managing and leasing the space while actively working to dispose of the associated property . the reduction in the federal deposit insurance premium resulted from the deposit insurance fund reserve ratio exceeding the official required reserve ratio , which in turn generated credits to qualified participating banks . these credits have been fully utilized in fiscal 2020. financial condition investment portfolio for the year ended september 30 , 2020 , the average volume of investment securities decreased by $ 5.1 million to approximately $ 43.2 million or 3.7 percent of average interest- earning assets , from $ 48.3 million or 4.3 percent of average interest- earning assets , in fiscal 2019. at september 30 , 2020 , the total investment portfolio amounted to $ 46.5 million , an increase of $ 5.6 million from september 30 , 2019. the increase in the investment portfolio was primarily due to purchases of $ 30.1 million , partially offset by maturities , calls and principal repayments in the amount of $ 15.8 million and sales in the amount of $ 8.9 million during fiscal 2020. at september 30 , 2020 , the principal components of the investment portfolio were government agency obligations , federal agency obligations , including -38- mortgage-backed securities , obligations of u.s. states and political subdivision , corporate bonds and notes , a trust preferred security and equity securities . during the year ended september 30 , 2020 , volume related factors decreased investment revenue by $ 125,000 , while rate related factors increased investment revenue by $ 108,000. the yield on investments increased by twenty-five basis points to 2.71 percent from a yield of 2.46 percent during the year ended september 30 , 2019. the investment revenue decreased in fiscal 2020 compared to fiscal 2019 due primarily to decreased average volume . as of september 30 , 2020 , the estimated fair value of the available-for-sale securities disclosed below was primarily dependent upon the movement in market interest rates , particularly given the negligible inherent credit risk associated with these securities . these investment securities are comprised of securities that are rated investment grade by at least one bond credit rating service . as of september 30 , 2020 , the company held five corporate securities and one single issuer trust preferred security which were in an unrealized loss position . although the fair value will fluctuate as the market interest rates move , management believes that these fair values will recover as the underlying portfolios mature and are reinvested in market rate yielding investments . the company does not intend to sell and expects that it is not more likely than not that it will be required to sell these securities until such time as the value recovers or the securities mature . management does not believe any individual unrealized loss as of september 30 , 2020 represents other-than-temporary impairment . securities available-for-sale are a part of the company 's interest rate risk management strategy and may be sold in response to changes in interest rates , changes in prepayment risk , liquidity management and other factors . the company continues to reposition the investment portfolio as part of an overall corporate-wide strategy to produce reasonable and consistent margins where feasible , while attempting to limit risks inherent in the company 's balance sheet . for fiscal 2020 , proceeds of available-for-sale investment securities sold amounted to approximately $ 8.9 million . there were gains of approximately $ 352,000 associated with these sales . for fiscal 2019 , proceeds of available-for-sale investment securities sold amounted to approximately $ 2.1 million . gross realized gains on investment securities sold amounted to approximately $ 28,000. the varying amount of sales from the available-for-sale portfolio over the past few years , reflect the significant volatility present in the market . given the historic low interest rates prevalent in the market , it is necessary for the company to protect itself from interest rate exposure . securities that once appeared to be sound long-term investments can , after changes in the market , become securities that the company wishes to sell to avoid losses and mismatches of interest-earning assets and interest-bearing liabilities at a later time . -39- the table
