Basis of Accounting, Policy	The Consolidated Financial Statements have been prepared in conformity with U.S. GAAP and include the accounts of IHC and its consolidated subsidiaries. All significant intercompany transactions have been eliminated in consolidation. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect: (i) the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements; and (ii) the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In March 2020, the World Health Organization declared the outbreak of COVID-19 a global health pandemic and the United States declared a national health emergency. COVID-19 has led to large scale disruption in the global economy, market instability and widespread unemployment in the United States. The COVID-19 outbreak is a fluid situation and as it evolves, the duration of COVID-19 and its potential effects on our business cannot be certain. Regulatory mandates have affected, and we anticipate will continue to impact, the insurance industry. We currently cannot predict if there will be a material impact to our business, results of operations or financial condition in future reporting periods. Consequently, future changes in market conditions may impact estimates used in the preparation of our financial statements associated with evaluations of goodwill and other intangible assets for impairment, estimates associated with the determination of valuation allowances related to net operating loss carryforwards, and estimates of certain losses under insurance contracts. These estimates may all be subject to substantial adjustments in future periods. In addition, volatile market conditions may result in further declines in the fair value of our investment portfolio and possible impairments of certain securities.
