Financial condition, liquidity and capital resources
Sources and uses of funds
We are organized as a holding company with our operations conducted through our subsidiaries, including our wholly owned insurance subsidiaries, Benchmark, which is domiciled in Kansas and commercially domiciled in California, and ALIC, which is domiciled in Utah. Accordingly, the holding company may receive cash through (i) loans from banks, (ii) draws on a revolving loan agreement, (iii) issuance of equity and debt securities, (iv) corporate service fees from our operating subsidiaries, (v) payments from our subsidiaries pursuant to our consolidated tax allocation agreement and other transactions and (vi) dividends from our non-insurance subsidiaries and, subject to certain limitations discussed below, dividends from our insurance subsidiaries. We also may use the proceeds from these sources to contribute funds to the insurance subsidiaries in order to support premium growth, reduce our reliance on reinsurance, retire indebtedness on preferred stock, pay taxes and for other business purposes.
We receive corporate service fees from the operating subsidiaries to reimburse us for most of the operating expenses that we incur. Reimbursement of expenses through corporate service fees is based on the actual costs that we expect to incur with no mark-up above our expected costs.
