charge to goodwill and a $1.3 million charge to indefinite-lived intangible assets. In connection with its normal process for evaluating impairment triggering events, the Company determined that a significant decline in its market capitalization below its stockholders’ equity during the first quarter of 2020 indicated the impairment of the goodwill and indefinite-lived intangible assets included in our balance sheet. Further contributing to the pre-tax loss was higher interest expense of $0.2 million, as well as the lower revenue discussed above. The pre-tax loss was partially reduced by lower operating expenses of $0.8 million, primarily as a result of decreased salary and related expenses of $2.7 million, largely due to incentive compensation accrual adjustments, and decreased travel and related expenses of $0.1 million, partially offset by higher professional service expenses of $1.1 million, occupancy and other general expenses of $0.9 million.

Sources and Uses of Funds
Our sources of funds are from insurance-related operations, financing activities and investing activities. Major sources of funds from operations include premiums collected (net of policy cancellations and premiums ceded), commissions, and processing and service fees. As a holding company, Hallmark is dependent on dividend payments and management fees from its subsidiaries to meet operating expenses and debt obligations. As of September 30, 2020, Hallmark and its non-insurance company subsidiaries had $11.9 million in unrestricted cash and cash equivalents, including $4.5 million held in premium and claim trust accounts. As of that date, our insurance subsidiaries held $174.8 million of unrestricted cash and cash equivalents, as well as $417.6 million in debt securities with an average modified duration of 0.9 years.
