The Company’s overall loss and LAE experience significantly improved year-over-year. Private passenger auto experienced higher loss and LAE ratios due to reduced favorable claim reserve development in 2018 compared to 2017. Experience on the non-standard auto business improved from last year, and also reflects a lower loss and LAE ratio on the acquired Direct Auto business. The assumed reinsurance portion of the all other segment experience was favorable due to a relatively quiet catastrophe period in 2018, compared to a high level of hurricanes and wildfires in 2017.
Amortization of Deferred Policy Acquisition Costs and Other Underwriting and General Expenses
Direct Auto will be restricted by the insurance laws of Illinois as to the amount of dividends or other distributions it may pay to NI Holdings. Illinois law sets the maximum amount of dividends that may be paid by Direct Auto during any twelve-month period after notice to, but without prior approval of, the Illinois Department of Insurance. This amount cannot exceed the greater of (i) 10% of the Company’s surplus as regards policyholders as of the preceding December 31, or (ii) the Company’s statutory net income for the preceding calendar year (excluding realized capital gains). Dividends in excess of this amount are considered “extraordinary” and are subject to the approval of the Illinois Department of Insurance.
Our other financial instruments, aside from investments, are cash and cash equivalents, premiums and agents’ balances receivable, and accrued expenses and accounts payable. The carrying amounts for cash and cash equivalents, premiums and agents’ balances receivable, and accrued expenses and accounts payable approximate their fair value based on their short-term nature. Other invested assets that do not have observable inputs and little or no market activity are carried on a cost basis. All other invested assets have been assessed for impairment. The carrying value of these other invested assets was $1,954 at December 31, 2018 and $1,972 at December 31, 2017.
The Company limits the maximum net loss that can arise from large risks or risks in concentrated areas of exposure by reinsuring (ceding) certain levels of risks to other insurers or reinsurers, either on an automatic basis under general reinsurance contracts known as “treaties” or by negotiation on substantial individual risks. Ceded reinsurance is treated as the risk and liability of the assuming companies.
These pro forma amounts have been calculated after applying the Company’s accounting policies and adjusting the results of Direct Auto’s operations to reflect the deferral and amortization of policy acquisition costs and the additional amortization that would have been charged assuming the fair value adjustments to intangibles had been applied from January 1, 2017, with the related income tax effects. The gain is recognized in the first quarter of 2017 instead of the third quarter of 2018 for these pro forma amounts.
The amount available for payment of dividends from Nodak Insurance to NI Holdings during 2019 without the prior approval of the North Dakota Insurance Department is $17,588 based upon the policyholders’ surplus of Nodak Insurance at December 31, 2018. Prior to its payment of any extraordinary dividend, Nodak Insurance will be required to provide notice of the dividend to the North Dakota Insurance Department. This notice must be provided to the North Dakota Insurance Department 30 days prior to the payment of an extraordinary dividend and 10 days prior to the payment of an ordinary dividend. The North Dakota Insurance Department has the power to limit or prohibit dividend payments if Nodak Insurance is in violation of any law or regulation. These restrictions or any subsequently imposed restrictions may affect our future liquidity. No dividends were declared or paid by Nodak Insurance during the years ended December 31, 2018 or 2017.
On March 1, 2018, the Compensation Committee awarded PSUs to select executives. PSUs are promises to issue actual shares of common stock at the end of a vesting period, if certain performance conditions are met. The PSUs granted to employees under the Plan were based on salary and include a three-year book value cumulative growth target with threshold and stretch goals. They will vest on the third anniversary of the grant date, subject to the participant’s continuous employment through the vesting date and the level of performance achieved. Dividend equivalents on PSUs are accrued and paid in cash at the end of the performance period in accordance with the level of performance achieved, but are subject to forfeiture until the underlying shares become vested. Participants do not have voting rights with respect to PSUs.
We have four primary reportable operating segments, which consist of private passenger auto insurance, non-standard auto insurance, home and farm insurance, and crop insurance. A fifth segment captures all other insurance coverages we sell, including commercial coverages and our assumed reinsurance lines of business. We operate only in the United States, and no single customer or agent provides 10 percent or more of our revenues. The following tables provide available information of these segments for the years ended December 31, 2018, 2017, and 2016. For presentation in these tables, “LAE” refers to loss adjustment expenses.
