Item 7.Management’s Discussion and Analysis of Financial Condition and Results of Operations

We begin this MD&A with the overall strategy of AMERCO, followed by a description of, and strategy related to, our operating segments to give the reader an overview of the goals of our businesses and the direction in which our businesses and products are moving. We then discuss our critical accounting policies and estimates that we believe are important to understanding the assumptions and judgments incorporated in our reported financial results. Next, we discuss our results of operations for fiscal 2018 compared with fiscal 2017, and for fiscal 2017 compared with fiscal 2016 which are followed by an analysis of liquidity changes in our balance sheets and cash flows, and a discussion of our financial commitments in the sections entitled Liquidity and Capital Resources and Disclosures about Contractual Obligations and Commercial Commitments. We conclude this MD&A by discussing our outlook for fiscal 2019.

This MD&A should be read in conjunction with the other sections of this Annual Report, including Item 1: Business, Item 6: Selected Financial Data and Item 8: Financial Statements and Supplementary Data. The various sections of this MD&A contain a number of forward-looking statements, as discussed under the caption, Cautionary Statements Regarding Forward-Looking Statements, all of which are based on our current expectations and could be affected by the uncertainties and risk factors described throughout this Annual Report and particularly under the section Item 1A: Risk Factors. Our actual results may differ materially from these forward-looking statements.

AMERCO has a fiscal year that ends on the 31 st of March for each year that is referenced. Our insurance company subsidiaries have fiscal years that end on the 31 st of December for each year that is referenced. They have been consolidated on that basis. Our insurance companies’ financial reporting processes conform to calendar year reporting as required by state insurance departments. Management believes that consolidating their calendar year into our fiscal year financial statements does not materially affect the presentation of financial position or results of operations. We disclose all material events, if any, occurring during the intervening period. Consequently, all references to our insurance subsidiaries’ years 2017, 2016 and 2015 correspond to fiscal 2018, 2017 and 2016 for AMERCO.

Overall Strategy

Our overall strategy is to maintain our leadership position in the North American “do-it-yourself” moving and storage industry. We accomplish this by providing a seamless and integrated supply chain to the “do-it-yourself” moving and storage market. As part of executing this strategy, we leverage the brand recognition of U-Haul with our full line of moving and self-storage related products and services and the convenience of our broad geographic presence.

Our primary focus is to provide our customers with a wide selection of moving rental equipment, convenient self-storage rental facilities and portable moving and storage units and related moving and self-storage products and services. We are able to expand our distribution and improve customer service by increasing the amount of moving equipment and storage rooms and portable moving and storage units available for rent, expanding the number of independent dealers in our network and expanding and taking advantage of our eMove capabilities.

Property and Casualty Insurance is focused on providing and administering property and casualty insurance to U-Haul and its customers, its independent dealers and affiliates. 

Life Insurance is focused on long-term capital growth through direct writing and reinsuring of life, Medicare supplement and annuity products in the senior marketplace.

Description of Operating Segments

AMERCO’s three reportable segments are:

Life Insurance provides life and health insurance products primarily to the senior market through the direct writing and reinsuring of life insurance, Medicare supplement and annuity policies.

Critical Accounting Policies and Estimates

Our financial statements have been prepared in accordance with the generally accepted accounting principles (“GAAP”) in the United States. The methods, estimates and judgments we use in applying our accounting policies can have a significant impact on the results we report in our financial statements. Note 3, Accounting Policies, of the Notes to Consolidated Financial Statements in Item 8: Financial Statements and Supplementary Data, in this Annual Report summarizes the significant accounting policies and methods used in the preparation of our consolidated financial statements and related disclosures. Certain accounting policies require us to make difficult and subjective judgments and assumptions, often as a result of the need to estimate matters that are inherently uncertain.

Following is a detailed description of the accounting policies that we deem most critical to us and that require management’s most difficult and subjective judgments. These estimates are based on historical experience, observance of trends in particular areas, information and valuations available from outside sources and on various other assumptions that are believed to be reasonable under the circumstances and which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual amounts may differ from these estimates under different assumptions and conditions; such differences may be material.

We also have other policies that we consider key accounting policies, such as revenue recognition; however, these policies do not meet the definition of critical accounting estimates, because they do not generally require us to make estimates or judgments that are difficult or subjective. The accounting policies that we deem most critical to us, and involve the most difficult, subjective or complex judgments include the following:

Principles of Consolidation

We apply Accounting Standards Codification (“ASC”) 810 - Consolidation (“ASC 810”) in our principles of consolidation. ASC 810 addresses arrangements where a company does not hold a majority of the voting or similar interests of a variable interest entity (“VIE”). A company is required to consolidate a VIE if it has determined it is the primary beneficiary. ASC 810 also addresses the policy when a company owns a majority of the voting or similar rights and exercises effective control.

As promulgated by ASC 810, a VIE is not self-supportive due to having one or both of the following conditions: (i) it has an insufficient amount of equity for it to finance its activities without receiving additional subordinated financial support or (ii) its owners do not hold the typical risks and rights of equity owners. This determination is made upon the creation of a variable interest and is re-assessed on an on-going basis should certain changes in the operations of a VIE, or its relationship with the primary beneficiary trigger a reconsideration under the provisions of ASC 810. After a triggering event occurs the facts and circumstances are utilized in determining whether or not a company is a VIE, which other company(ies) have a variable interest in the entity, and whether or not the company’s interest is such that it is the primary beneficiary.

We will continue to monitor our relationships with the other entities regarding who is the primary beneficiary, which could change based on facts and circumstances of any reconsideration events.

Recoverability of Property, Plant and Equipment

Our property, plant and equipment is stated at cost. Interest expense incurred during the initial construction of buildings is considered part of cost. Depreciation is computed for financial reporting purposes using the straight-line or an accelerated method based on a declining balance formula over the following estimated useful lives: rental equipment 2-20 years and buildings and non-rental equipment 3-55 years. Routine maintenance costs are charged to operating expense as they are incurred. Gains and losses on dispositions of property, plant and equipment are netted against depreciation expense when realized. Equipment depreciation is recognized in amounts expected to result in the recovery of estimated residual values upon disposal, i.e., minimize gains or losses. In determining the depreciation rate, historical disposal experience, holding periods and trends in the market for vehicles are reviewed. As a result of changes in IRS regulations regarding the capitalization of assets, beginning in the first quarter of fiscal 2017, we raised the value threshold before certain assets are capitalized within our depreciation policy. This change in threshold, results in the immediate recognition of reported operating costs with a lagging decrease in depreciation expense over the term that these assets would have been depreciated. This change in threshold is expected to benefit us through the immediate recognition of tax deductible costs.

We regularly perform reviews to determine whether facts and circumstances exist which indicate that the carrying amount of assets, including estimates of residual value, may not be recoverable or that the useful life of assets are shorter or longer than originally estimated. Reductions in residual values (i.e., the price at which we ultimately expect to dispose of revenue earning equipment) or useful lives will result in an increase in depreciation expense over the remaining life of the equipment. Reviews are performed based on vehicle class, generally subcategories of trucks and trailers. We assess the recoverability of our assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their estimated remaining lives against their respective carrying amounts. We consider factors such as current and expected future market price trends on used vehicles and the expected life of vehicles included in the fleet. Impairment, if any, is based on the excess of the carrying amount over the fair value of those assets. If asset residual values are determined to be recoverable, but the useful lives are shorter or longer than originally estimated, the net book value of the assets is depreciated over the newly determined remaining useful lives.

For our box truck fleet we utilize an accelerated method of depreciation based upon a declining formula. Under the declining balances method (2.4 times declining balance), the book value of a rental truck is reduced by approximately 16%, 13%, 11%, 9%, 8%, 7%, and 6% of cost during years one through seven, respectively, and then reduced on a straight line basis to a salvage value of 15% by the end of year fifteen. Comparatively, a standard straight line approach would reduce the book value by approximately 5.7% per year over the life of the truck.

Although we intend to sell our used vehicles for prices approximating book value, the extent to which we realize a gain or loss on the sale of used vehicles is dependent upon various factors including but not limited to, the general state of the used vehicle market, the age and condition of the vehicle at the time of its disposal and the depreciation rates with respect to the vehicle . We typically sell our used vehicles at our sales centers throughout the United States and Canada, on our website at uhaul.com/trucksales or by phone at 1-866-404-0355. Additionally, we sell a large portion of our pickup and cargo van fleet at automobile dealer auctions.

Insurance Reserves

Liabilities for life insurance and certain annuity and health policies are established to meet the estimated future obligations of policies in force, and are based on mortality, morbidity and withdrawal assumptions from recognized actuarial tables which contain margins for adverse deviation. In addition, liabilities for health, disability and other policies include estimates of payments to be made on insurance claims for reported losses and estimates of losses incurred, but not yet reported (“IBNR”). Liabilities for annuity contracts consist of contract account balances that accrue to the benefit of the policyholders.

Insurance reserves for Property and Casualty Insurance and U-Haul take into account losses incurred based upon actuarial estimates and are management’s best approximation of future payments.  These estimates are based upon past claims experience and current claim trends as well as social and economic conditions such as changes in legal theories and inflation.  These reserves consist of case reserves for reported losses and a provision for IBNR losses, both reduced by applicable reinsurance recoverables, resulting in a net liability.

Due to the nature of the underlying risks and high degree of uncertainty associated with the determination of the liability for future policy benefits and claims, the amounts to be ultimately paid to settle these liabilities cannot be precisely determined and may vary significantly from the estimated liability, especially for long-tailed casualty lines of business such as excess workers’ compensation.  As a result of the long-tailed nature of the excess workers’ compensation policies written by Repwest during 1983 through 2001, it may take a number of years for claims to be fully reported and finally settled.

On a regular basis insurance reserve adequacy is reviewed by management to determine if existing assumptions need to be updated. In determining the assumptions for calculating workers’ compensation reserves, management considers multiple factors including the following:

• Claimant longevity
• Cost trends associated with claimant treatments
• Changes in ceding entity and third party administrator reporting practices
• Changes in environmental factors including legal and regulatory
• Current conditions affecting claim settlements
• Future economic conditions including inflation

We have reserved each claim based upon the accumulation of current claim costs projected through each claimant’s life expectancy, and then adjusted for applicable reinsurance arrangements.  Management reviews each claim bi-annually or more frequently, if there are changes in facts or circumstances to determine if the estimated life-time claim costs have increased and then adjusts the reserve estimate accordingly at that time.  We have factored in an estimate of what the potential cost increases could be in our IBNR liability.  We have not assumed settlement of the existing claims in calculating the reserve amount, unless it is in the final stages of completion.

Continued increases in claim costs, including medical inflation and new treatments and medications could lead to future adverse development resulting in additional reserve strengthening.  Conversely, settlement of existing claims or if injured workers return to work or expire prematurely, could lead to future positive development.

Impairment of Investments

Investments are evaluated pursuant to guidance contained in ASC 320 - Investments - Debt and Equity Securities to determine if and when a decline in market value below amortized cost is other-than-temporary. Management makes certain assumptions or judgments in its assessment including but not limited to: our ability and intent to hold the security, quoted market prices, dealer quotes or discounted cash flows, industry factors, financial factors, and issuer specific information such as credit strength. Other-than-temporary impairment in value is recognized in the current period operating results. There were no write downs in fiscal 2018, 2017 and 2016, respectively.

Income Taxes

We file a consolidated tax return with all of our legal subsidiaries.

Our tax returns are periodically reviewed by various taxing authorities. The final outcome of these audits may cause changes that could materially impact our financial results. Please see Note 13, Provision for Taxes, of the Notes to Consolidated Financial Statements included in Item 8: Financial Statements and Supplementary Data, of this Annual Report for more information.

Fair Values

Fair values of cash equivalents approximate carrying value due to the short period of time to maturity. Fair values of short-term investments, investments available-for-sale, long-term investments, mortgage loans and notes on real estate, and interest rate swap contracts are based on quoted market prices, dealer quotes or discounted cash flows. Fair values of trade receivables approximate their recorded value.

Our financial instruments that are exposed to concentrations of credit risk consist primarily of temporary cash investments, trade receivables, reinsurance recoverables and notes receivable. Limited credit risk exists on trade receivables due to the diversity of our customer base and their dispersion across broad geographic markets. We place our temporary cash investments with financial institutions and limit the amount of credit exposure to any one financial institution.

We have mortgage receivables, which potentially expose us to credit risk. The portfolio of notes is principally collateralized by self-storage facilities and commercial properties. We have not experienced any material losses related to the notes from individual or groups of notes in any particular industry or geographic area. The estimated fair values were determined using the discounted cash flow method and using interest rates currently offered for similar loans to borrowers with similar credit ratings.

The carrying amount of long-term debt and short-term borrowings are estimated to approximate fair value as the actual interest rate is consistent with the rate estimated to be currently available for debt of similar term and remaining maturity.

Other investments including short-term investments are substantially current or bear reasonable interest rates. As a result, the carrying values of these financial instruments approximate fair value.

Recent Accounting Pronouncements

Please see Note 3, Accounting Policies, of the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Form 10-K.

Self-moving equipment rental revenues increased $116.9 million during fiscal 2018, compared with fiscal 2017 largely due to growth in both one-way and In-Town ® transactions. Over the course of fiscal 2018 we added new Company owned locations to our retail network and increased the number of trucks, trailers, and towing devices in our rental fleet.

Self-storage revenues increased $37.0 million during fiscal 2018, compared with fiscal 2017.  The average monthly amount of occupied square feet increased by 8.9% during fiscal 2018, compared with the same period last year.  The growth in revenues and square feet rented comes from a combination of improved rates per square foot, occupancy gains at existing locations and from the addition of new facilities to the portfolio. Over the last twelve months, we added approximately 3.7 million net rentable square feet, or a 13.4% increase, with approximately 1.2 million of that coming on during the fourth quarter of fiscal 2018.

Sales of self-moving and self-storage products and services increased $8.5 million during fiscal 2018, compared with fiscal 2017. Increases were recognized in the sales of moving supplies, propane and towing accessories and related installations.

Life insurance premiums decreased $8.9 million during fiscal 2018, compared with fiscal 2017 primarily due to decreased Medicare supplement premiums.

Property and casualty insurance premiums increased $4.8 million during fiscal 2018, compared with fiscal 2017 due to an increase in Safetow ® and Safestor ® sales, which is a reflection of the increased equipment and storage rental transactions.

Net investment and interest income increased $8.2 million during fiscal 2018, compared with fiscal 2017 due to a larger invested asset base at our insurance companies.   

Other revenue increased $12.3 million during fiscal 2018, compared with fiscal 2017, primarily coming from growth in our U-Box ® program.

As a result of the items mentioned above, revenues for AMERCO and its consolidated entities were $3,601.1 million for fiscal 2018 as compared with $3,421.8 million for fiscal 2017.

Listed below are revenues and earnings from operations at each of our operating segments for fiscal 2018 and 2017. The insurance companies’ years ended December 31, 2017 and 2016.

Total costs and expenses increased $157.3 million during fiscal 2018, compared with fiscal 2017. Our insurance segments accounted for $4.8 million of the increase.

Excluding net gains on the disposal of real estate, total costs and expenses increased $349.1 million during fiscal 2018, compared with fiscal 2017. Operating expenses at Moving and Storage increased $238.2 million.  In the second quarter of fiscal 2017, we recognized the difference between the accrued amount and actual settlement amount of the PODS Enterprises, Inc. (“PEI”) case as a $24.6 million reduction of operating expenses. Excluding this effect in the prior year, operating expenses for Moving and Storage increased $213.6 million.  This was primarily due to increased personnel costs, equipment maintenance, payment processing fees, new facility related costs and property tax.  Repair costs, primarily associated with the portion of the fleet nearing resale, accounted for $72.9 million of the increase for fiscal 2018.  Personnel bonuses associated with tax reform for the entire workforce combined with bonuses for our field management team accounted for $31.1 million of the increase.   Lease expense decreased $3.4 million as a result of our shift in financing new equipment on the balance sheet versus through operating leases.  Net gains from the disposal of rental equipment decreased $20.7 million.  Compared with fiscal 2017, we have sold more used trucks, however on average the trucks sold in fiscal 2018 had a higher average cost than in fiscal 2017 and average sales proceeds per truck were lower in fiscal 2018.  Depreciation expense associated with our rental fleet increased $56.5 million due to a larger fleet.  Depreciation expense on all other assets, largely from buildings and improvements increased $17.0 million. Net gains on disposal of real estate increased $191.8 million.  The increase resulted from the sale of a portion of our Chelsea, NY property which resulted in a pre-tax gain of $190.7 million.

As a result of the above mentioned changes in revenues and expenses, earnings from operations increased to $764.3 million for fiscal 2018, compared with $742.3 million for fiscal 2017.

Interest expense for fiscal 2018 was $126.7 million, compared with $113.4 million for fiscal 2017 due to an increase in borrowings in fiscal 2018 partially offset by lower borrowing costs. In addition, we incurred costs associated with the early extinguishment of debt during the third quarter of fiscal 2017 of $0.5 million for the write-off of unamortized transaction costs related to defeased debt.

Income tax benefit (expense) was $153.0 million for fiscal 2018, compared with ($229.9) million for fiscal 2017 due to the effects of the Tax Reform Act as enacted on December 22, 2017. Our effective tax rate was (24.0%) of net income before taxes for fiscal 2018, compared to 36.6% in the prior-year period. The decrease in our deferred tax liability resulting from the application of the new Federal income tax rate accounted for a $371.5 million decrease, partially offset by a $11.7 million one-time increase resulting from the deemed repatriation of foreign earnings and a $4.0 million one-time increase resulting from Phase Three tax on our Life Insurance subsidiary. Excluding the one-time benefits and charges mentioned above, our effective tax rate for all of fiscal 2018, post Tax Reform Act, was 31.8%, compared with 36.6% for fiscal 2017. We project that our effective tax rate for the fiscal year ending March 31, 2019 will be approximately 24.3%. See Note 13, of the Notes to Consolidated Financial Statements included in Item 8: Financial Statements and Supplementary Data, of this Annual Report for more information on income taxes.

As a result of the above mentioned items, earnings available to common shareholders were $790.6 million for fiscal 2018, compared with $398.4 million for fiscal 2017.

Basic and diluted earnings per common share for fiscal 2018 were $40.36, compared with $20.34 for fiscal 2017.

The weighted average common shares outstanding basic and diluted were 19,588,889 for fiscal 2018, compared with 19,586,606 for fiscal 2017.

Self-moving equipment rental revenues increased $64.9 million during fiscal 2017, compared with fiscal 2016.  During fiscal 2017, we continued to grow our rental system through the expansion of our distribution network and by increasing the number of trucks, trailers and towing devices available to our customers. Both In-Town ® and one-way transactions increased compared with fiscal 2016, which resulted in improved revenue results.

Self-storage revenues increased $38.9 million during fiscal 2017, compared with fiscal 2016.  The average monthly amount of occupied square feet increased by 11.8% during fiscal 2017 compared with fiscal 2016.  The growth in revenues and square feet rented came from a combination of improved rates per square foot, occupancy gains at existing locations and from the addition of new facilities to our real estate portfolio. During the twelve months ended March 31, 2017, we added approximately 3.4 million net rentable square feet, or a 14.0% increase, with approximately 1.0 million net rental square feet added during the fourth quarter of fiscal 2017.

Sales of self-moving and self-storage products and services increased $1.5 million during fiscal 2017, compared with fiscal 2016, primarily from the sale of moving supplies.

Life insurance premiums increased $0.9 million during fiscal 2017, compared with fiscal 2016 primarily due to increased life and Medicare supplement premiums.

Property and casualty insurance premiums increased $2.3 million during fiscal 2017, compared with fiscal 2016 due to an increase in Safetow ® and Safestor ® sales, which was a reflection of the increased equipment and storage rental transactions.

Net investment and interest income increased $15.7 million during fiscal 2017, compared with fiscal 2016 due to a larger invested asset base at our insurance companies and gains generated from our mortgage loan portfolio.   

Other revenue increased $19.5 million during fiscal 2017, compared with fiscal 2016, primarily coming from growth in our U-Box ® program.

As a result of the items mentioned above, revenues for AMERCO and its consolidated entities were $3,421.8 million for fiscal 2017 as compared with $3,275.5 million for fiscal 2016.

Listed below are revenues and earnings from operations at each of our operating segments for fiscal 2017 and 2016. The insurance companies’ years ended December 31, 2016 and 2015.

Total costs and expenses increased $270.7 million during fiscal 2017, compared with fiscal 2016. Our insurance segments accounted for $18.1 million of the increase primarily due to increased benefit costs.

Moving and Storage total costs and expenses increased $252.7 million.  In October 2016, we settled the litigation with PEI. As part of this settlement, we paid $41.4 million to PEI. In fiscal 2015 and fiscal 2016, we recorded $66.0 million as accrued contingencies and interest related to this lawsuit. During the second quarter of fiscal 2017, we recognized the difference between our contingency accrual and the actual settlement as a $24.6 million reduction of operating expenses.  Excluding the effect of the reversal of this accrual during fiscal 2017, operating expenses increased $122.9 million for Moving and Storage, primarily due to increased personnel costs, equipment maintenance and property tax, as well as a change in the accounting threshold for the expensing of smaller capital items that led to the additional costs being recognized immediately versus over time through depreciation expense. Net gains from the disposal of rental equipment decreased $65.7 million.  Compared with fiscal 2016, we have sold fewer used trucks, however on average the trucks sold had a higher average cost and we experienced a decrease in the average sales proceeds per unit. Depreciation expense associated with our rental fleet increased $66.9 million due to a larger fleet.  Depreciation expense on all other assets, largely from buildings and improvements increased $25.2 million. Net gains on disposal of real estate increased $3.0 million.  Lease expense decreased $12.4 million as a result of our shift in financing new equipment on the balance sheet versus through operating leases.

As a result of the above mentioned changes in revenues and expenses, earnings from operations decreased to $742.3 million for fiscal 2017, compared with $866.6 million for fiscal 2016.

Interest expense for fiscal 2017 was $113.4 million, compared with $97.7 million for fiscal 2016 due to an increase in borrowings in fiscal 2017 partially offset by lower borrowing costs. In addition, we incurred costs associated with the early extinguishment of debt during the third quarter of fiscal 2017 of $0.5 million for the write-off of unamortized transaction costs related to defeased debt.

Income tax expense was $229.9 million for fiscal 2017, compared with $279.9 million for fiscal 2016. The decrease was due to lower pretax earnings for fiscal 2017. The effective tax rate was 36.6% and 36.4% for fiscal 2017 and 2016, respectively.

As a result of the above mentioned items, earnings available to common shareholders were $398.4 million for fiscal 2017, compared with $489.0 million for fiscal 2016.

Basic and diluted earnings per common share for fiscal 2017 were $20.34, compared with $24.95 for fiscal 2016.

The weighted average common shares outstanding basic and diluted were 19,586,606 for fiscal 2017, compared with 19,596,110 for fiscal 2016.

Self-moving equipment rental revenues increased $117.4 million during fiscal 2018, compared with fiscal 2017 largely due to growth in both one-way and In-Town ® transactions. Over the course of fiscal 2018 we added new Company owned locations to our retail network and increased the number of trucks, trailers, and towing devices in our rental fleet.

Self-storage revenues increased $37.0 million during fiscal 2018, compared with fiscal 2017.  The average monthly amount of occupied square feet increased by 8.9% during fiscal 2018, compared with the same period last year.  The growth in revenues and square feet rented comes from a combination of improved rates per square foot, occupancy gains at existing locations and from the addition of new facilities to the portfolio. Over the last twelve months, we added approximately 3.7 million net rentable square feet, or a 13.4% increase, with approximately 1.2 million of that coming on during the fourth quarter of fiscal 2018.

Sales of self-moving and self-storage products and services increased $8.5 million during fiscal 2018, compared with fiscal 2017. Increases were recognized in the sales of moving supplies, propane and towing accessories and related installations.

Net investment and interest income increased $2.5 million during fiscal 2018, compared with fiscal 2017.

Other revenue increased $11.7 million during fiscal 2018, compared with fiscal 2017, primarily coming from growth in our U-Box ® program.

The Company owns and manages self-storage facilities. Self-storage revenues reported in the consolidated financial statements represent Company-owned locations only. Self-storage data for our owned storage locations follows:

The approximately 3.7 million net rentable square feet that we’ve added during fiscal 2018 was a mix of existing storage locations we acquired and new development. On average, the occupancy rate of this new capacity on the date it was added was approximately 5%.

Excluding net gains on the disposal of real estate, total costs and expenses increased $346.6 million during fiscal 2018, compared with fiscal 2017. Operating expenses at Moving and Storage increased $238.2 million.  In the second quarter of fiscal 2017, we recognized the difference between the accrued amount and actual settlement amount of the PEI case as a $24.6 million reduction of operating expenses. Excluding this effect in the prior year, operating expenses for Moving and Storage increased $213.6 million.  This was primarily due to increased personnel costs, equipment maintenance, payment processing fees, new facility related costs and property tax.  Repair costs, primarily associated with the portion of the fleet nearing resale, accounted for $72.9 million of the increase for fiscal 2018.  Personnel bonuses associated with tax reform for the entire workforce combined with bonuses for our field management team accounted for $31.1 million of the increase.   Lease expense decreased $3.3 million as a result of our shift in financing new equipment on the balance sheet versus through operating leases.  Net gains from the disposal of rental equipment decreased $20.7 million.  Compared with fiscal 2017, we have sold more used trucks, however on average the trucks sold in fiscal 2018 had a higher average cost than in fiscal 2017 and the average sales proceeds per truck were lower in fiscal 2018.  Depreciation expense associated with our rental fleet increased $56.5 million due to a larger fleet.  Depreciation expense on all other assets, largely from buildings and improvements increased $17.0 million. Net gains on disposal of real estate increased $191.8 million.  The increase was caused by the sale of a portion of our Chelsea, NY property which resulted in a pre-tax gain of $190.7 million.

As a result of the above mentioned changes in revenues and expenses, earnings from operations for Moving and Storage before consolidation of the equity in the earnings of the insurance subsidiaries increased to $711.8 million for fiscal 2018 as compared with $688.9 million for fiscal 2017.

Equity in the earnings of AMERCO’s insurance subsidiaries increased $11.2 million for fiscal 2018, compared with fiscal 2017.

As a result of the above mentioned changes in revenues and expenses, earnings from operations increased to $758.8 million for fiscal 2018, compared with $724.7 million for fiscal 2017.

Self-moving equipment rental revenues increased $64.9 million during fiscal 2017, compared with fiscal 2016.  During fiscal 2017, we continued to grow our rental system through the expansion of our distribution network and by increasing the number of trucks, trailers and towing devices available to our customers. Both In-Town ® and one-way transactions increased compared with fiscal 2016, this resulted in our improved revenue results.

Self-storage revenues increased $38.9 million during fiscal 2017, compared with fiscal 2016.  The average monthly amount of occupied square feet increased by 11.8% during fiscal 2017 compared with fiscal 2016.  The growth in revenues and square feet rented camesfrom a combination of improved rates per square foot, occupancy gains at existing locations and from the addition of new facilities to the portfolio. During the twelve months ended March 31, 2017, we added approximately 3.4 million net rentable square feet, or a 14.0% increase, with approximately 1.0 million net rental square feet added during the fourth quarter of fiscal 2017.

Sales of self-moving and self-storage products and services increased $1.5 million during fiscal 2017, compared with fiscal 2016.  Increases were recognized in the sales of moving supplies.  

Net investment and interest income increased $0.9 million during fiscal 2017, compared with fiscal 2016. 

Other revenue increased $19.7 million during fiscal 2017, compared with fiscal 2016 primarily coming from growth in our U-Box ® program rentals.

The Company owns and manages self-storage facilities. Self-storage revenues reported in the consolidated financial statements represent Company-owned locations only. Self-storage data for our owned storage locations follows:

The approximately 3.4 million net rentable square feet that we’ve added during fiscal 2017 was a mix of existing storage locations we acquired and new development. On average, the occupancy rate of this new capacity on the date it was added was approximately 11%.

Total costs and expenses increased $252.7 million during fiscal 2017, compared with fiscal 2016.  In October 2016, we settled the litigation with PEI. As part of this settlement, we paid $41.4 million to PEI. In fiscal 2015 and fiscal 2016, we recorded $66.0 million as accrued contingencies and interest related to this lawsuit. During the second quarter of fiscal 2017, we recognized the difference between our contingency accrual and the actual settlement as a $24.6 million reduction of operating expenses.  Excluding the effect of the reversal of this accrual in fiscal 2017, operating expenses for Moving and Storage increased $122.9 million, primarily due to personnel costs, equipment maintenance and property tax, as well as a change in the accounting threshold for the expensing of smaller capital items that led to the additional costs being recognized immediately versus over time though depreciation expense. Net gains from the disposal of rental equipment decreased $65.7 million.  Compared with fiscal 2016, we have sold fewer used trucks, however on average the trucks sold had a higher average cost and we experienced a decrease in the average sales proceeds per unit. Depreciation expense associated with our rental fleet increased $66.9 million due to a larger fleet.  Depreciation expense on all other assets, largely from buildings and improvements increased $25.2 million. Net gains on disposal of real estate increased $3.0 million.  Lease expense decreased $12.4 million as a result of our shift in financing new equipment on the balance sheet versus through operating leases.

As a result of the above mentioned changes in revenues and expenses, earnings from operations for Moving and Storage before consolidation of the equity in the earnings of the insurance subsidiaries decreased to $688.9 million for fiscal 2017 as compared with $813.1 million for fiscal 2016.

Equity in the earnings of AMERCO’s insurance subsidiaries increased $0.3 million for fiscal 2017, compared with fiscal 2016.

As a result of the above mentioned changes in revenues and expenses, earnings from operations decreased to $724.7 million for fiscal 2017, compared with $848.6 million for fiscal 2016.

Property and Casualty Insurance

2017 Compared with 2016

Net premiums were $58.8 million and $52.3 million for the years ended December 31, 2017 and 2016, respectively. A significant portion of Repwest’s premiums are from policies sold in conjunction with U-Haul rental transactions. The premium growth corresponded with the increased moving and storage transactions at U-Haul.

Net investment income was $15.8 million and $16.7 million for the years ended December 31, 2017 and 2016, respectively. The change was primarily due to a decrease in realized capital gains of $0.9 million. The December 31, 2016 results were impacted by above average early pay-offs within the mortgage loan portfolio.

Net operating expenses were $32.7 million and $28.4 million for the years ended December 31, 2017 and 2016, respectively. This was due to an increase in commissions and loss adjusting fees.

Benefits and losses incurred were $16.0 million and $13.4 million for the years ended December 31, 2017 and 2016, respectively. The increase was due to an increase in policies sold and related claims activity.

As a result of the above mentioned changes in revenues and expenses, pretax earnings from operations were $25.9 million and $27.2 million for the years ended December 31, 2017 and 2016, respectively.

Property and Casualty Insurance

2016 Compared with 2015

Net premiums were $52.3 million and $50.0 million for the years ended December 31, 2016 and 2015, respectively. A significant portion of Repwest’s premiums are from policies sold in conjunction with U-Haul rental transactions. The premium growth corresponded with the increased moving and storage transactions at U-Haul.

Net investment income was $16.7 million and $14.8 million for the years ended December 31, 2016 and 2015, respectively. The change was primarily due to an increase in realized capital gains of $1.3 million and a $1.1 million increase in fixed maturity income due to a larger invested asset base.

Net operating expenses were $28.4 million and $28.0 million for the years ended December 31, 2016 and 2015, respectively.

Benefits and losses incurred were $13.4 million and $12.3 million for the years ended December 31, 2016 and 2015, respectively. The increase was due to an increase in policies sold and related claims activity.

As a result of the above mentioned changes in revenues and expenses, pretax earnings from operations were $27.2 million and $24.5 million for the years ended December 31, 2016 and 2015, respectively.

Life Insurance

2017 Compared with 2016

Net premiums were $154.7 million and $163.6 million for the years ended December 31, 2017 and 2016, respectively.  Medicare Supplement premiums decreased by $9.3 million due to the reduction in new sales and declined premiums on the existing business offset by rate increases on renewal premiums. The remaining lines of business had a net increase of $0.4 million. Deferred annuity deposits were $296.8 million or $93.7 million above the prior year and are accounted for on the balance sheet as deposits rather than premiums.

Net investment income was $84.2 million and $77.5 million for the years ended December 31, 2017 and 2016, respectively. Investment income and realized gains from fixed maturities increased $10.9 million from a larger invested asset base, partially offset by a $4.3 million decrease in gains from our mortgage loan portfolio.

Net operating expenses were $22.1 million and $22.4 million for the years ended December 31, 2017 and 2016, respectively. The decrease was primarily due to a reduction in commission expense from decreased Medicare Supplement premiums.

Benefits and losses incurred were flat at $169.3 million for both the years ended December 31, 2017 and 2016. A decrease of $9.2 million in Medicare supplement benefits from an improved benefit to premium ratio was offset by an increase in the remaining lines of business. Life insurance benefits increased $1.6 million with increased mortality while interest credited to policyholders increased by $7.3 million from a larger annuity base. Other benefits increased $0.3 million.

Amortization of deferred acquisition costs (“DAC”), sales inducement asset (“SIA”) and the value of business acquired (“VOBA”) was $24.5 million and $26.2 million for the years December 31, 2017 and 2016, respectively. The decrease was primarily due to additional DAC amortization in the prior year generated by added gains on discounted mortgage loan investments partially offset by the increased amortization from a larger DAC asset in the current year.

As a result of the above mentioned changes in revenues and expenses, pretax earnings from operations were $28.0 million and $27.6 million for the years ended December 31, 2017 and 2016, respectively.

Life Insurance

2016 Compared with 2015

Net premiums were $163.6 million and $162.7 million for the years ended December 31, 2016 and 2015, respectively.  Life premiums increased $0.4 million primarily from the increase in renewal premiums offset by a reduction in new sales and reinsurance premiums.  An additional increase of $0.7 million was from supplemental contract considerations. Medicare supplement and other health premiums decreased $0.2 million. Deferred annuity deposits were $203.1 million or $65.1 million below the prior year and are accounted for on the balance sheet as deposits rather than premiums.

Net investment income was $77.5 million and $64.0 million for the years ended December 31, 2016 and 2015, respectively. An increase of $14.6 million in net investment income was attributable to a larger asset base and the gains from our mortgage loans portfolio, which was partially offset by a $1.1 million decrease in capital gains.

Net operating expenses were $22.4 million and $23.0 million for the years ended December 31, 2016 and 2015, respectively. The decrease was primarily due to a reduction in acquisition expenses from the decrease in annuity sales.

Benefits and losses incurred were $169.3 million and $155.1 million for the years ended December 31, 2016 and 2015, respectively. Medicare Supplement benefits increased by $8.8 million as a result of the increase in total policies in force from prior and new sales and the increased benefit to premium ratio. Life, annuities and other health benefits decreased $0.2 million. Interest credited to policyholders increased $5.6 million as a result of the increased deferred annuity deposit base and lower interest credited on policyholder accounts indexed to an S&P index in the third quarter of 2015.

Amortization of DAC, SIA and VOBA was $26.2 million and $23.3 million for the years ended December 31, 2016 and 2015, respectively. The increase was due to an additional Annuity DAC amortization generated by the investment gains along with increased amortization associated with a larger DAC asset. This was partially offset by a decrease in Medicare supplement amortization.    

As a result of the above mentioned changes in revenues and expenses, pretax earnings from operations were $27.6 million and $29.8 million for the years ended December 31, 2016 and 2015, respectively.

Net cash used by investing activities decreased $285.6 million in fiscal 2018, compared with fiscal 2017. Purchases of property, plant and equipment, which are reported net of cash from sales and lease-back transactions, decreased $53.1 million, while cash from the sales of property, plant and equipment increased $212.3 million largely due to the sale of a portion of our Chelsea location in New York. For our insurance subsidiaries, net cash used in investing activities increased $66.4 million compared with the prior year. Net cash deposited in real estate acquisition escrow accounts decreased $31.4 million in fiscal 2018, compared with a net increase of $38.1 million in fiscal 2017.

Net cash provided by financing activities decreased $207.1 million in fiscal 2018, as compared with fiscal 2017 due to a decrease in borrowings of $244.2 million, net increase in repayments of debt and capital leases of $72.4 million, an increase in annuity deposits, net of withdrawals, by Life Insurance of $83.3 million and a decrease in dividends paid of $28.9 million.

Liquidity and Capital Resources and Requirements of Our Operating Segments

Moving and Storage

To meet the needs of our customers, U-Haul maintains a large fleet of rental equipment. Capital expenditures have primarily consisted of new rental equipment acquisitions and the buyouts of existing fleet from leases. The capital to fund these expenditures has historically been obtained internally from operations and the sale of used equipment and externally from debt and lease financing. In the future, we anticipate that our internally generated funds will be used to service the existing debt and fund operations. U-Haul estimates that during fiscal 2019 the Company will reinvest in its truck and trailer rental fleet approximately $450 million, net of equipment sales and excluding any lease buyouts. For fiscal 2018, the Company invested, net of sales, approximately $515 million before any lease buyouts in its truck and trailer fleet. Fleet investments in fiscal 2019 and beyond will be dependent upon several factors including availability of capital, the truck rental environment and the used-truck sales market. We anticipate that the fiscal 2019 investments will be funded largely through debt financing, external lease financing and cash from operations. Management considers several factors including cost and tax consequences when selecting a method to fund capital expenditures. Our allocation between debt and lease financing can change from year to year based upon financial market conditions which may alter the cost or availability of financing options.

Real Estate has traditionally financed the acquisition of self-storage properties to support U-Haul's growth through debt financing and funds from operations. The Company’s plan for the expansion of owned storage properties includes the acquisition of existing self-storage locations from third parties, the acquisition and development of bare land, and the acquisition and redevelopment of existing buildings not currently used for self-storage. The Company expects to fund these development projects through a combination of internally generated funds along with borrowings against existing properties as they operationally mature. For fiscal 2018, the Company invested $609.7 million in real estate acquisitions, new construction and renovation and repair. For fiscal 2019, the timing of new projects will be dependent upon several factors, including the entitlement process, availability of capital, weather, and the identification and successful acquisition of target properties. U-Haul's growth plan in self-storage also includes the expansion of the U-Haul Storage Affiliate program, which does not require significant capital.

Net capital expenditures (purchases of property, plant and equipment less proceeds from the sale of property, plant and equipment and lease proceeds) were $666.6 million, $932.0 million and $969.9 million for fiscal 2018, 2017 and 2016, respectively. The components of our net capital expenditures are provided in the following table:

Moving and Storage continues to hold significant cash and we believe has access to additional liquidity. Management may invest these funds in our existing operations, expand our product lines or pursue external opportunities in the self-moving and storage marketplace, pay dividends or reduce existing indebtedness where possible.

Property and Casualty Insurance

State insurance regulations restrict the amount of dividends that can be paid to stockholders of insurance companies. As a result, Property and Casualty Insurance's assets are generally not available to satisfy the claims of AMERCO, or its legal subsidiaries.

We believe that stockholders equity at the Property and Casualty operating segment remains sufficient and we do not believe that its ability to pay ordinary dividends to AMERCO will be restricted per state regulations.

Our Property and Casualty operating segment stockholder’s equity was $211.2 million, $180.9 million, and $160.6 million at December 31, 2017, 2016, and 2015, respectively. The increase in 2017 compared with 2016 resulted from net earnings of $22.9 million, an increase in accumulated other comprehensive income of $10.4 million offset by a $2.9 million one-time reclassification to move the effect of the rate reduction from other comprehensive income to retained earnings. Property and Casualty Insurance does not use debt or equity issues to increase capital and therefore has no direct exposure to capital market conditions other than through its investment portfolio.

Life Insurance

Life Insurance manages its financial assets to meet policyholder and other obligations including investment contract withdrawals and deposits. Life Insurance's net deposit increase for the year ended December 31, 2017 was $219.3 million. State insurance regulations restrict the amount of dividends that can be paid to stockholders of insurance companies. As a result, Life Insurance's funds are generally not available to satisfy the claims of AMERCO ® or its legal subsidiaries.

Our Life Insurance operating segment stockholder’s equity was $332.9 million, $296.1 million, and $271.7 million at December 31, 2017, 2016 and 2015, respectively. The increase in 2017 compared with 2016 resulted from earnings of $24.1 million and an increase in accumulated other comprehensive income of $19.0 million primarily due to the effect of interest rate changes on the fixed maturity portion of the investment portfolio and a decrease in deferred income tax from a reduced corporate tax rate under the Tax Cut and Jobs Act. This was offset by a $6.3 million one-time reclassification to move the effect of the rate reduction from other comprehensive income to retained earnings. Life Insurance has not historically used debt or equity issues to increase capital and therefore has not had any significant direct exposure to capital market conditions other than through its investment portfolio. However, as of December 31, 2017, Oxford had outstanding deposits of $60.0 million through its membership in the Federal Home Loan Bank (“FHLB”). For a more detailed discussion of this deposit, please see Note 9, Borrowings, of the Notes to Consolidated Financial Statements.

Cash Provided from Operating Activities by Operating Segments

Moving and Storage

Net cash provided by operating activities was $858.6 million, $983.6 million and $994.0 million in fiscal 2018, 2017 and 2016. Reduced profitability at the Moving and Storage segment combined with a $31.8 million increase in income tax payment accounted for the majority of the decline in fiscal 2018.

Property and Casualty Insurance

Net cash provided by operating activities was $20.6 million, $18.2 million, and $19.0 million for the years ended December 31, 2017, 2016, and 2015, respectively. The variation in cash activity was consistent with typical claims activity.

Property and Casualty Insurance’s cash and cash equivalents and short-term investment portfolios amounted to $17.0 million, $20.7 million, and $24.3 million at December 31, 2017, 2016, and 2015, respectively. These balances reflect funds in transition from maturity proceeds to long-term investments. Management believes this level of liquid assets, combined with budgeted cash flow, is adequate to meet foreseeable cash needs. Capital and operating budgets allow Property and Casualty Insurance to schedule cash needs in accordance with investment and underwriting proceeds.

Life Insurance

Net cash provided by operating activities was $57.2 million, $56.3 million and $32.4 million for the years ended December 31, 2017, 2016 and 2015, respectively. The increase in operating cash flows was due to the increase in investment income and lower benefit payments offset by a decrease in collected premiums.

In addition to cash flows from operating activities and financing activities, a substantial amount of liquid funds are available through Life Insurance's short-term portfolio and its membership in the FHLB. At December 31, 2017, 2016 and 2015, cash and cash equivalents and short-term investments amounted to $50.7 million, $20.6 million and $25.5 million, respectively. Management believes that the overall sources of liquidity are adequate to meet foreseeable cash needs.

Liquidity and Capital Resources - Summary

We believe we have the financial resources needed to meet our business plans including our working capital needs. We continue to hold significant cash and have access to existing credit facilities and additional liquidity to meet our anticipated capital expenditure requirements for investment in our rental fleet, rental equipment and storage acquisitions and build outs. 

Our borrowing strategy is primarily focused on asset-backed financing and rental equipment leases. As part of this strategy, we seek to ladder maturities and focus on fixing our interest rates. While each of these loans typically contains provisions governing the amount that can be borrowed in relation to specific assets, the overall structure is flexible with no limits on overall Company borrowings. Management believes it has adequate liquidity between cash and cash equivalents and unused borrowing capacity in existing credit facilities to meet the current and expected needs of the Company over the next several years. At March 31, 2018, we had available borrowing capacity under existing credit facilities of $180.0 million. It is possible that circumstances beyond our control could alter the ability of the financial institutions to lend us the unused lines of credit. We believe that there are additional opportunities for leverage in our existing capital structure. For a more detailed discussion of our long-term debt and borrowing capacity, please see Note 9, Borrowings, of the Notes to Consolidated Financial Statements included in Item 8: Financial Statements and Supplementary Data, of this Annual Report.

Fair Value of Financial Instruments

Certain assets and liabilities are recorded at fair value on the consolidated balance sheets and are measured and classified based upon a three tiered approach to valuation. ASC 820 requires that financial assets and liabilities recorded at fair value be classified and disclosed in a Level 1, Level 2 or Level 3 category. For more information, please see Note 15, Fair Value Measurements, of the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Form 10-K. 

The available-for-sale securities held by the Company are recorded at fair value. These values are determined primarily from actively traded markets where prices are based either on direct market quotes or observed transactions. Liquidity is a factor considered during the determination of the fair value of these securities. Market price quotes may not be readily available for certain securities or the market for them has slowed or ceased. In situations where the market is determined to be illiquid, fair value is determined based upon limited available information and other factors including expected cash flows. At March 31, 2018, we had $0.3 million of available-for-sale assets classified in Level 3.

The interest rate swaps held by us as hedges against interest rate risk for our variable rate debt are recorded at fair value. These values are determined using pricing valuation models which include broker quotes for which significant inputs are observable. They include adjustments for counterparty credit quality and other deal-specific factors, where appropriate and are classified as Level 2.

(a) These estimated obligations for unpaid losses and loss adjustment expenses include case reserves for reported claims and IBNR claims estimates and are net of expected reinsurance recoveries. The ultimate amount to settle both the case reserves and IBNR is an estimate based upon historical experience and current trends and such estimates could materially differ from actual results. The assumptions do not include future premiums. Due to the significant assumptions employed in this model, the amounts shown could materially differ from actual results.

(b) These estimated obligations are based on mortality, morbidity, withdrawal and lapse assumptions drawn from our historical experience and adjusted for any known trends. These obligations include expected interest crediting but no amounts for future annuity deposits or premiums for life and Medicare supplement policies.  The cash flows shown above are undiscounted for interest and as a result total outflows for all years shown significantly exceed the corresponding liabilities of $1,808.9 million included in our consolidated balance sheet as of March 31, 2018. Life Insurance expects to fully fund these obligations from their invested asset portfolio. Due to the significant assumptions employed in this model, the amounts shown could materially differ from actual results. 

(c) These estimated obligations are primarily the Company’s self insurance accruals for portions of the liability coverage for our rental equipment. The estimates for future settlement are based upon historical experience and current trends. Due to the significant assumptions employed in this model, the amounts shown could materially differ from actual results.

As presented above, contractual obligations on debt and guarantees represent principal payments while contractual obligations for operating leases represent the notional payments under the lease arrangements.

ASC 740 - Income Taxes liabilities and interest of $44.2 million is not included above due to uncertainty surrounding ultimate settlements, if any.

Off Balance Sheet Arrangements

The Company uses off-balance sheet arrangements in situations where management believes that the economics and sound business principles warrant their use.

AMERCO utilizes operating leases for certain rental equipment and facilities with terms expiring substantially through 2024. In the event of a shortfall in proceeds from the sales of the underlying rental equipment assets, AMERCO has guaranteed $15.7 million of residual values at March 31, 2018 for these assets at the end of their respective lease terms. AMERCO has been leasing rental equipment since 1987. To date, we have not experienced residual value shortfalls related to these leasing arrangements. Using the average cost of fleet related debt as the discount rate, the present value of AMERCO’s minimum lease payments and residual value guarantees was $26.0 million at March 31, 2018.

Historically, we have used off-balance sheet arrangements in connection with the expansion of our self-storage business. For more information please see Note 19, Related Party Transactions, of the Notes to Consolidated Financial Statements included in Item 8: Financial Statements and Supplementary Data, of this Annual Report. These arrangements were primarily used when our overall borrowing structure was more limited. We do not face similar limitations currently and off-balance sheet arrangements have not been utilized in our self-storage expansion in recent years. In the future, we will continue to identify and consider off-balance sheet opportunities to the extent such arrangements would be economically advantageous to us and our stockholders. SAC Holdings, Four SAC Self-Storage Corporation (“4 SAC”), Five SAC Self-Storage Corporation (“5 SAC”), Galaxy Investments, L.P. (“Galaxy”) and Private Mini are substantially controlled by Blackwater. Blackwater is wholly-owned by WGHLP, which is owned by Mark V. Shoen (a significant shareholder) and various trusts associated with Edward J. Shoen (our Chairman of the Board, President and a significant shareholder) and Mark V. Shoen.

We currently manage the self-storage properties owned or leased by Blackwater and Mercury pursuant to a standard form of management agreement, under which we receive a management fee of between 4% and 10% of the gross receipts plus reimbursement for certain expenses. We received management fees, exclusive of reimbursed expenses, of $29.5 million, $27.8 million and $27.1 million from the above mentioned entities during fiscal 2018, 2017 and 2016, respectively. This management fee is consistent with the fee received for other properties we previously managed for third parties. Mark V. Shoen controls the general partner of Mercury. The limited partner interests of Mercury are indirectly owned by Mark V. Shoen, James P. Shoen (a significant shareholder), and a trust benefitting the children and grandchildren of Edward J. Shoen (our Chairman of the Board, President and a significant shareholder).

We lease space for marketing company offices, vehicle repair shops and hitch installation centers from subsidiaries of Blackwater. Total lease payments pursuant to such leases were $2.7 million, $2.7 million and $2.6 million for fiscal years 2018, 2017 and 2016, respectively. The terms of the leases are similar to the terms of leases for other properties owned by unrelated parties that are leased by us.

At March 31, 2018, subsidiaries of Blackwater acted as U-Haul independent dealers. The financial and other terms of the dealership contracts with the aforementioned companies and their subsidiaries are substantially identical to the terms of those with our other independent dealers whereby commissions are paid by us based on equipment rental revenues. We paid the above mentioned entities $58.6 million, $57.1 million and $54.7 million in commissions pursuant to such dealership contracts during fiscal 2018, 2017 and 2016, respectively.

During fiscal 2018, a subsidiary of ours held a junior unsecured note of SAC Holdings. Substantially all of the equity interest of SAC Holdings is controlled by Blackwater. We do not have an equity ownership interest in SAC Holdings. We recorded interest income of $3.3 million, $4.9 million and $5.0 million and received cash interest payments of $8.7 million, $4.5 million and $4.6 million from SAC Holdings during fiscal 2018, 2017 and 2016, respectively. The largest aggregate amount of notes receivable outstanding during fiscal 2018 was $48.1 million. In December 2017, this note and interest receivable was repaid in full as we received payments of $53.0 million.

These agreements along with a note with subsidiaries of Blackwater, excluding Dealer Agreements, provided revenues of $26.9 million, expenses of $2.7 million and cash flows of $77.6 million during fiscal 2018. Revenues and commission expenses related to the Dealer Agreements were $273.6 million and $58.6 million, respectively during fiscal 2018.

Fiscal 2019 Outlook

We will continue to focus our attention on increasing transaction volume and improving pricing, product and utilization for self-moving equipment rentals.  Maintaining an adequate level of new investment in our truck fleet is an important component of our plan to meet our operational goals. Revenue in the U-Move ® program could be adversely impacted should we fail to execute in any of these areas. Even if we execute our plans, we could see declines in revenues primarily due to unforeseen events including adverse economic conditions or heightened competition that is beyond our control.

With respect to our storage business, we have added new locations and expanded at existing locations. In fiscal 2019, we are actively looking to acquire new locations, complete current projects and increase occupancy in our existing portfolio of locations. New projects and acquisitions will be considered and pursued if they fit our long-term plans and meet our financial objectives. We will continue to invest capital and resources in the U-Box ® program throughout fiscal 2019.

Property and Casualty Insurance will continue to provide loss adjusting and claims handling for
U-Haul and underwrite components of the Safemove ® , Safetow ® , Safemove Plus ® , Safestor ® , and Safestor Mobile ® protection packages to U-Haul customers.

Life Insurance is pursuing its goal of expanding its presence in the senior market through the sales of its Medicare supplement, life and annuity policies. This strategy includes growing its agency force, expanding its new product offerings, and pursuing business acquisition opportunities.

Quarterly Results (unaudited)

The quarterly results shown below are derived from unaudited financial statements for the eight quarters beginning April 1, 2016 and ending March 31, 2018. We believe that all necessary adjustments have been included in the amounts stated below to present fairly, and in accordance with GAAP, such results. Moving and Storage operations are seasonal and proportionally more of the Company’s revenues and net earnings from its Moving and Storage operations are generated in the first and second quarters of each fiscal year (April through September). The operating results for the periods presented are not necessarily indicative of results for any future period.
