ABM Industries (ABM) 10-Q2022 Q1 Quarterly report

This Form 10-Q contains both historical and forward-looking statements regarding ABM and its subsidiaries (collectively referred to as “ABM,” “we,” “us,” “our,” or the “Company”). We make forward-looking statements related to future expectations, estimates, and projections that are uncertain and often contain words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “forecast,” “intend,” “likely,” “may,” “outlook,” “plan,” “predict,” “should,” “target,” or other similar words or phrases. These statements are not guarantees of future performance and are subject to known and unknown risks, uncertainties, and assumptions that are difficult to predict. Particular risks and uncertainties that could cause our actual results to be materially different from those expressed in our forward-looking statements include those listed below.

The list of factors above is illustrative and by no means exhaustive. Additional information regarding these and other risks and uncertainties we face is contained in our Annual Report on Form 10-K for the year ended October 31, 2021, and in other reports (including all amendments to those reports) we file from time to time with the Securities and Exchange Commission (“SEC”).

We urge readers to consider these risks and uncertainties in evaluating our forward-looking statements. We caution readers not to place undue reliance upon any such forward-looking statements, which speak only as of the date made. We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law.

ABM is a leading provider of integrated facility services with a mission to make a difference, every person, every day. We are organized into 4 industry groups and 1 Technical Solutions segment:

Through these groups, we offer janitorial, facilities engineering, parking, and specialized mechanical and electrical technical solutions, on a standalone basis or in combination with other services.

The accompanying unaudited consolidated financial statements have been prepared in accordance with (i) United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and (ii) the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of our management, our unaudited consolidated financial statements and accompanying notes (the “Financial Statements”) include all normal recurring adjustments that are necessary for the fair statement of the interim periods presented. Interim results of operations are not necessarily indicative of results for the full year. The Financial Statements should be read in conjunction with our audited consolidated financial statements (and notes thereto) in our Annual Report on Form 10-K for the year ended October 31, 2021. Unless otherwise indicated, all references to years are to our fiscal years, which end on October 31.

COVID-19 has resulted in a worldwide health Pandemic. To date, the Pandemic has surfaced in regions all around the world and resulted in business slowdowns and shutdowns, as well as global travel restrictions. In these Financial Statements, we have assessed the current impact of the Pandemic on our financial condition, results of operations, and cash flows as well as on our estimates, forecasts, and accounting policies. We have made additional disclosures of these assessments, as necessary. Given the unprecedented nature of this situation, we cannot reasonably estimate the full impact the Pandemic will have on our financial condition, results of operations, or cash flows in the foreseeable future. The ultimate impact of the Pandemic on our company is highly uncertain and will depend on future developments, and such impacts could exist for an extended period of time, even after the Pandemic subsides.

We round amounts in the Financial Statements to millions and calculate all percentages and per-share data from the underlying whole-dollar amounts. Thus, certain amounts may not foot, crossfoot, or recalculate based on reported numbers due to rounding.

We operate certain parking facilities under management reimbursement arrangements. Under these arrangements, we manage the parking facilities for management fees and pass through the revenues and expenses associated with the facilities to the owners. These revenues and expenses are reported in equal amounts as costs reimbursed from our managed locations:

No other recently adopted accounting standards have had a significant impact on our fiscal 2022 consolidated financial statements.

On September 30, 2021, we acquired Able, a leading facilities services company headquartered in San Francisco, California, for a preliminary net cash purchase price of $741.7 million (the “Able Acquisition”). Pursuant to the terms of the purchase agreement, approximately $12.1 million of the cash consideration was placed into escrow accounts, of which approximately $8.2 million was placed into escrow to satisfy any applicable indemnification claims for a period of 12 months.

Our preliminary purchase price allocation is based on information that is currently available, and we are continuing to evaluate the underlying inputs and assumptions used in our valuations. Accordingly, the purchase price consideration and allocations are subject to, among other items: working capital adjustments, further analysis of tax accounts, legal matters, and the final valuation of insurance claims reserves. During the three months ended January 31, 2022, we adjusted our purchase price allocation for probable litigation losses, as described below, and refined certain other estimates.

The following table summarizes the preliminary acquisition accounting on the date of acquisition as previously reported at year-end 2021 and at the end of the first quarter of 2022:

The unaudited Consolidated Statements of Comprehensive Income (Loss) for the three months ended January 31, 2022, includes $307.7 million of revenue and $14.4 million of operating income attributable to the operations of Able, which are included in our B&I segment. We also incurred $4.1 million of acquisition-related costs and $4.2 million of integration costs during the three months ended January 31, 2022, which are included in selling, general and administrative expenses in the accompanying unaudited Consolidated Statements of Comprehensive Income (Loss).

The following table presents our unaudited pro forma results as though the acquisition occurred on November 1, 2020. These results include adjustments for the estimated amortization of intangible assets, interest expense, and the income tax impact of the pro forma adjustments at the statutory rate of 28%. These unaudited pro

Able is a party to a number of lawsuits, claims, and proceedings incident to the operation of the business, including those pertaining to labor and employment, contracts, personal injury, and other matters, some of which allege substantial monetary damages. Some of these actions may be brought as class actions on behalf of a class or purported class of employees.

If, during the purchase price allocation period, we can reasonably determine the fair values of a pre-acquisition contingency, then we will include that amount in the purchase price allocation. If we are unable to determine the fair value of a pre-acquisition contingency at the end of the measurement period, then we will evaluate whether to include an amount in the purchase price allocation based on whether it is probable a liability had been incurred and whether an amount can be reasonably estimated. Subsequent to the end of the measurement period, any adjustment to amounts recorded for a pre-acquisition contingency will be included within acquisition-related costs in the period in which the adjustment is determined.

During the three months ended January 31, 2022, we adjusted our purchase price allocation for probable litigation losses in Able legal matters where a reasonable estimate of the loss could be made from $0.9 million to $12.3 million. We do not accrue for contingent losses that, in our judgment, are considered to be reasonably possible but not probable. The estimation of reasonably possible losses also requires the analysis of multiple possible outcomes that often depend on judgments about potential actions by third parties. Our management currently estimates the range of loss for all reasonably possible losses for which a reasonable estimate of the loss can be made for Able legal matters is between zero and $1.9 million. In some cases, although a loss is probable or reasonably possible, we cannot reasonably estimate the maximum potential losses for probable matters or the range of losses for reasonably possible matters. Therefore, our accrual for probable losses and our estimated range of loss for reasonably possible losses do not represent our maximum possible exposure.

On January 31, 2022, the Company sold a group of customer contracts for healthcare technology management within our Technical Solutions segment for $8.5 million and recognized a gain of $7.7 million during the three months ended January 31, 2022, which is included in selling, general and administrative expenses in the accompanying unaudited Consolidated Statements of Comprehensive Income (Loss).

We generate revenues under several types of contracts, which are further explained below. Generally, the type of contract is determined by the nature of the services provided by each of our major service lines throughout our reportable segments; therefore, we disaggregate revenues from contracts with customers into major service lines. We have determined that disaggregating revenues into these categories best depicts how the nature, amount, timing, and uncertainty of revenues and cash flows are affected by economic factors. Our reportable segments are B&I, M&D, Education, Aviation, and Technical Solutions, as described in Note 12, “Segment Information.”

We have arrangements under various contract types, as described in Note 2, “Basis of Presentation and Significant Accounting Policies,” in our Annual Report on Form 10-K for the year ended October 31, 2021.

Certain arrangements involve variable consideration (primarily per transaction fees, reimbursable expenses, and sales-based royalties). We do not estimate the variable consideration for these arrangements; rather, we recognize these variable fees as they are earned. Some of our contracts, often related to Airline Services, may also include performance incentives based on variable performance measures that are ascertained exclusively by future performance and therefore cannot be estimated at contract inception and are recognized as revenue once known and mutually agreed upon. We include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current, and forecasted) that is reasonably available to us.

The majority of our contracts include performance obligations that are primarily satisfied over time as we provide the related services. These contract types include: monthly fixed-price; square-foot; cost-plus; work orders; transaction-price; hourly; management reimbursement; leased location; allowance; energy savings contracts; and fixed-price repair and refurbishment contracts, as well as our franchise and royalty fee arrangements. We recognize revenue as the services are performed using a measure of progress that is determined by the contract type. Generally, most of our contracts are cancellable by either party without a substantive penalty, and the majority have a notification period of 30 to 60 days.

We primarily account for our performance obligations under the series guidance, using the as-invoiced practical expedient when applicable. We apply the as-invoiced practical expedient to record revenue as the services are provided, given the nature of the services provided and the frequency of billing under the customer contracts. Under this practical expedient, we recognize revenue in an amount that corresponds directly with the value to the customer of our performance completed to date and for which we have the right to invoice the customer.

At January 31, 2022, performance obligations that were unsatisfied or partially unsatisfied for which we expect to recognize revenue totaled $310.7 million. We expect to recognize revenue on approximately 80% of the remaining performance obligations over the next 12 months, with the remainder recognized thereafter, based on our estimates of project timing.

These amounts exclude variable consideration primarily related to: (i) contracts where we have determined that the contract consists of a series of distinct service periods and revenues are based on future performance that cannot be estimated at contract inception; (ii) parking contracts where we and the customer share the gross revenues or operating profit for the location; and (iii) contracts where transaction prices include performance incentives that are based on future performance and therefore cannot be estimated at contract inception. We apply the practical expedient that permits exclusion of information about the remaining performance obligations with original expected durations of one year or less.

Contract Balances

The timing of revenue recognition, billings, and cash collections results in contract assets and contract liabilities, as further explained below. The timing of revenue recognition may differ from the timing of invoicing to customers.

Contract assets primarily consist of billed trade receivables, unbilled trade receivables, and costs incurred in excess of amounts billed. Billed and unbilled trade receivables represent amounts from work completed in which we have an unconditional right to bill our customer. Costs incurred in excess of amounts billed typically arise when the revenue recognized on projects exceeds the amount billed to the customer. These amounts are transferred to billed trade receivables when the rights become unconditional. Contract assets also include the capitalization of incremental costs of obtaining a contract with a customer, primarily commissions. Commissions expense is recognized on a straight-line basis over a weighted average expected customer relationship period.

Contract liabilities consist of deferred revenue and advance payments and billings in excess of revenue recognized. We generally classify contract liabilities as current since the related contracts are generally for a period

The following tables present the balances in our contract assets and contract liabilities:

In addition to assets and liabilities that are measured at fair value on a recurring basis, we are also required to measure certain items at fair value on a non-recurring basis. These assets can include: goodwill; intangible assets; property, plant and equipment; lease-related ROU assets; and long-lived assets that have been reduced to fair value when they are held for sale. If certain triggering events occur, or if an annual impairment test is required, then we would evaluate these non-financial assets for impairment. If an impairment were to occur, then the asset would be recorded at the estimated fair value, using primarily unobservable Level 3 inputs.

We use a combination of insured and self-insurance programs to cover workers’ compensation, general liability, automobile liability, property damage, and other insurable risks. For the majority of these insurance programs, we retain the initial $1.0 million to $1.5 million of exposure on a per-occurrence basis, either through deductibles or self-insured retentions. Beyond the retained exposures, we have varying primary policy limits ranging between $1.0 million and $5.0 million per occurrence. To cover general liability and automobile liability losses above these primary limits, we maintain commercial umbrella insurance policies that provide aggregate limits of $200.0 million. Our insurance policies generally cover workers’ compensation losses to the full extent of statutory requirements. Additionally, to cover property damage risks above our retained limits, we maintain policies that provide per occurrence limits of $75.0 million. We are also self-insured for certain employee medical and dental plans. We maintain stop-loss insurance for our self-insured medical plan under which we retain up to $0.5 million of exposure on a per-participant, per-year basis with respect to claims.

We maintain our reserves for workers’ compensation, general liability, automobile liability, and property damage insurance claims based upon known trends and events and the actuarial estimates of required reserves considering the most recently completed actuarial reports. We use all available information to develop our best estimate of insurance claims reserves as information is obtained. The results of actuarial reviews are used to estimate our insurance rates and insurance reserves for future periods and to adjust reserves, if appropriate, for prior years.

We review our self-insurance liabilities on a regular basis and adjust our accruals accordingly. Actual claims activity or development may vary from our assumptions and estimates, which may result in material losses or gains. As we obtain additional information that affects the assumptions and estimates used in our reserve liability calculations, we adjust our self-insurance rates and reserves for future periods and, if appropriate, adjust our reserves for claims incurred in prior accounting periods.

During the first quarter of 2022, we performed a comprehensive actuarial review of the majority of our casualty insurance programs to evaluate changes made to claims reserves and claims payment activity for the period of May 1, 2021, through October 31, 2021 (the “Actuarial Review”). The Actuarial Review was comprehensive in nature and was based on loss development patterns, trend assumptions, and underlying expected loss costs during the period analyzed.

Based on the results of the Actuarial Review, we decreased our total reserves related to prior periods for known claims as well as our estimate of the loss amounts associated with incurred but not reported claims (“IBNR claims”) by $25.2 million during the three months ended January 31, 2022. During the three months ended January 31, 2021, we decreased our total reserves related to prior periods by $11.4 million. We will continue to assess ongoing developments, which may result in further adjustments to reserves.

On September 1, 2017, we refinanced and replaced our then-existing $800.0 million credit facility with a new senior, secured five-year syndicated credit facility (the “Credit Facility”), consisting of a $900.0 million revolving line of credit (the “revolver”) and an $800.0 million amortizing term loan, both of which were scheduled to mature on September 1, 2022. In accordance with terms of the Credit Facility, the revolver was reduced to $800.0 million on September 1, 2018.

On June 28, 2021, the Company amended and restated the Credit Facility (the “Amended Credit Facility”), extending the maturity date to June 28, 2026, and increasing the capacity of the revolving credit facility from $800.0 million to $1.3 billion and the then-remaining term loan outstanding from $620.0 million to $650.0 million. The Amended Credit Facility provides for the issuance of up to $350.0 million for standby letters of credit and the issuance of up to $75.0 million in swingline advances. The obligations under the Amended Credit Facility are secured on a first-priority basis by a lien on substantially all of our assets and properties, subject to certain exceptions. Additionally, we may repay amounts borrowed under the Amended Credit Facility at any time without penalty.

The term loan and U.S.-dollar-denominated borrowings under the revolver bear interest at a rate equal to one-month LIBOR plus a spread based upon our leverage ratio. Euro- and sterling-denominated borrowings under the revolver bear at the interest rate of the Euro Interbank Offered Rate (“EURIBOR”) and the daily Sterling Overnight Index Average (“SONIA”) reference rate, respectively, plus a spread that is based upon our leverage ratio. The spread ranges from 1.375% to 2.250% for Eurocurrency loans and 0.375% to 1.250% for base rate loans. At January 31, 2022, the weighted average interest rate on our outstanding borrowings was 1.60%. We also pay a commitment fee, based on our leverage ratio and payable quarterly in arrears, ranging from 0.20% to 0.40% on the average daily unused portion of the line of credit. For purposes of this calculation, irrevocable standby letters of credit, which are issued primarily in conjunction with our insurance programs, and cash borrowings are included as outstanding under the line of credit.

The Amended Credit Facility contains certain covenants, including a maximum total net leverage ratio of 5.00 to 1.00, a maximum secured net leverage ratio of 4.00 to 1.00, and a minimum interest coverage ratio of 1.50 to 1.00, as well as other financial and non-financial covenants. In the event of a material acquisition, as defined in the Amended Credit Facility, we may elect to increase the maximum total net leverage ratio to 5.50 to 1.00 for a total of four fiscal quarters and increase the maximum secured net leverage ratio to 4.50 to 1.00 for a total of four fiscal quarters. Our borrowing capacity is subject to, and limited by, compliance with the covenants described above. At January 31, 2022, we were in compliance with these covenants.

The Amended Credit Facility also includes customary events of default, including: failure to pay principal, interest, or fees when due; failure to comply with covenants; the occurrence of certain material judgments; and a change in control of the Company. If certain events of default occur, including certain cross-defaults, insolvency, change in control, or violation of specific covenants, then the lenders can terminate or suspend our access to the Amended Credit Facility, declare all amounts outstanding (including all accrued interest and unpaid fees) to be immediately due and payable, and require that we cash collateralize the outstanding standby letters of credit.

We incurred deferred financing costs of $6.4 million in conjunction with the execution of the Amended Credit Facility and carried over $6.2 million of unamortized deferred financing from initial execution and previous amendments of the Credit Facility. Total deferred financing costs of $12.6 million, consisting of $4.9 million related to the term loan and $7.7 million related to the revolver, are being amortized to interest expense over the term of the Amended Credit Facility.

During the three months ended January 31, 2022, we made principal payments under the term loan of $8.1 million. As of January 31, 2022, the following principal payments are required under the term loan.

We enter into interest rate swaps to manage the interest rate risk associated with our floating-rate, LIBOR-based borrowings. Under these arrangements, we typically pay a fixed interest rate in exchange for LIBOR-based variable interest throughout the life of the agreement. We initially report the mark-to-market gain or loss on a derivative as a component of accumulated other comprehensive loss (“AOCL”) and subsequently reclassify the gain or loss into earnings when the hedged transactions occur and affect earnings. Interest payables and receivables under the swap agreements are accrued and recorded as adjustments to interest expense. All of our interest rate swaps have been designated and accounted for as cash flow hedges from inception. See Note 6, “Fair Value of Financial Instruments,” regarding the valuation of our interest rate swaps.

At January 31, 2022 and October 31, 2021, amounts recorded in AOCL for interest rate swaps were a gain of $0.3 million, net of taxes of $0.5 million, and a loss of $0.2 million, net of taxes of $0.3 million, respectively. These amounts included the gain associated with the interest rate swaps we terminated in 2018, which is being amortized to interest expense over the original term of our Credit Facility ending September 1, 2022. During the three months ended January 31, 2022, we amortized $1.1 million of this gain, net of taxes of $0.4 million, to interest expense. During the three months ended January 31, 2021, we amortized $1.2 million, net of taxes of $0.4 million. At January 31, 2022, the total amount expected to be reclassified from AOCL to earnings during the next 12 months is a gain of $0.5 million, net of taxes of $0.3 million.

We use letters of credit and surety bonds to secure certain commitments related to insurance programs and for other purposes. As of January 31, 2022, these letters of credit and surety bonds totaled $166.9 million and $700.4 million, respectively.

In some instances, we offer clients guaranteed energy savings under certain energy savings contracts. At January 31, 2022, total guarantees were $236.4 million and extend through 2042. We include the estimated costs of guarantees in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current, and forecasted) that is reasonably available to us. Historically, we have not incurred any material losses in connection with these guarantees.

We are a party to a number of lawsuits, claims, and proceedings incident to the operation of our business, including those pertaining to labor and employment, contracts, personal injury, and other matters, some of which allege substantial monetary damages. Some of these actions may be brought as class actions on behalf of a class or purported class of employees.

Litigation outcomes are difficult to predict, and the estimation of probable losses requires the analysis of multiple possible outcomes that often depend on judgments about potential actions by third parties. If one or more matters are resolved in a particular period in an amount in excess of or in a manner different than what we anticipated, this could have a material adverse effect on our financial position, results of operations, or cash flows.

In some cases, although a loss is probable or reasonably possible, we cannot reasonably estimate the maximum potential losses for probable matters or the range of losses for reasonably possible matters. Therefore, our accrual for probable losses and our estimated range of loss for reasonably possible losses do not represent our maximum possible exposure.

On September 20, 2018, the trial court entered an order defining 4 certified subclasses of janitors who were employed by the legacy ABM janitorial companies in California at any time between April 7, 2002, and April 30, 2013, on claims based on alleged previous automatic deduction practices for meal breaks, unpaid meal premiums, unpaid split shift premiums, and unreimbursed business expenses, such as mileage reimbursement for use of personal vehicles to travel between worksites. On February 1, 2019, the trial court held that the discovery related to PAGA claims allegedly arising after April 30, 2013, would be stayed until after the class and PAGA claims accruing prior to April 30, 2013, had been tried. The parties engaged in mediation in July 2019, which did not result in settlement of the case. On October 17, 2019, the plaintiffs filed a motion asking the trial court to certify additional classes based on an alleged failure to maintain time records, an alleged failure to provide accurate wage statements, and an alleged practice of combining meal and rest breaks. The trial court denied the plaintiffs’ motion to certify additional classes on December 26, 2019. The case was reassigned to a new judge on January 6, 2020. ABM filed motions for summary adjudication as to certain of plaintiffs’ class claims, and the trial court denied those motions in November 2020. The parties engaged in another mediation in January 2021, which did not result in a settlement of the case. Plaintiffs filed motions for summary adjudication and/or summary judgment on some claims in December 2020.

The settlement agreement is contingent upon the approval of the trial court. On August 11, 2021, the plaintiffs filed the motion for preliminary approval of class action settlement with the trial court. On December 7, 2021, the trial court issued its order granting preliminary approval of the class action settlement. Members of the class will receive notice of the settlement, and there will be an opportunity for them to object to the settlement before the trial court grants final approval of the settlement. On February 1, 2022, plaintiffs’ counsel filed a motion requesting that $46.7 million in attorneys’ fees be paid from the $140.0 million settlement fund. On February 16, 2022, a motion to intervene in the action was filed by proposed intervenor Rashad Jefferson, who had previously filed a separate PAGA action in Alameda County Superior Court that is currently pending. As a part of the motion to intervene, a stay was requested so that the proposed intervenor can investigate the settlement. Proposed intervenor also filed an objection to the PAGA settlement on February 14, 2022. A hearing for the motion to intervene is scheduled for March 14, 2022.

Plaintiffs filed a motion for final approval of the class settlement on February 24, 2022. The final approval hearing for the settlement is currently scheduled to take place on March 16, 2022. No payments will be made to employees until after the settlement is finally approved by the trial court.

Our quarterly tax provision is calculated using an estimated annual tax rate that is adjusted for discrete items occurring during the period to arrive at our effective tax rate. During the three months ended January 31, 2022 and 2021, we had effective tax rates of 24.2% and 26.7%, respectively, resulting in provisions for taxes of $24.3 million and $27.2 million, respectively. The difference between the effective tax rate and statutory rate is primarily related to tax credits and reserves.

Effective November 1, 2021, we reorganized our reportable segments to reflect our M&D industry group replacing our T&M industry group. Our current reportable segments consist of B&I, M&D, Education, Aviation, and Technical Solutions, as further described below. Refer to Note 2, “Basis of Presentation and Significant Accounting Policies,” for information related to our segment reorganization.

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is intended to facilitate an understanding of the results of operations and financial condition of ABM. This MD&A is provided as a supplement to, and should be read in conjunction with, our Financial Statements and our Annual Report on Form 10-K for the year ended October 31, 2021, which has been filed with the SEC. This MD&A contains forward-looking statements about our business, operations, and industry that involve risks and uncertainties, such as statements regarding our plans, objectives, expectations, and intentions. Our future results and financial condition may be materially different from those we currently anticipate. See “Forward-Looking Statements” for more information.

Throughout the MD&A, amounts and percentages may not recalculate due to rounding. Unless otherwise indicated, all information in the MD&A and references to years are based on our fiscal years, which end on October 31.

We review our self-insurance liabilities on a regular basis and adjust our accruals accordingly. Actual claims activity or development may vary from our assumptions and estimates, which may result in material losses or gains. As we obtain additional information that affects the assumptions and estimates used in our reserve liability

During the first quarter of 2022, we performed a comprehensive actuarial review of the majority of our casualty insurance programs to evaluate changes made to claims reserves and claims payment activity for the period of May 1, 2021, through October 31, 2021. The Actuarial Review was comprehensive in nature and was based on loss development patterns, trend assumptions, and underlying expected loss costs during the period analyzed. The Actuarial Review and other actuarial updates performed earlier in the year demonstrated that the changes we have made to our risk management programs continue to positively impact the frequency and severity of claims.

The claims management strategies and programs that we have implemented have resulted in improvements. Furthermore, we continue to adjust our reserves consistent with known fact patterns. Based on the results of the Actuarial Review, we decreased our total reserves related to prior periods for known claims as well as our estimate of the loss amounts associated with IBNR claims by $25.2 million during the three months ended January 31, 2022. The favorable review was primarily driven by improvements in the workers’ compensation program, reflecting reduced claim frequency related to the Pandemic and positive influences of claim closure projects and reserving practices. During the three months ended January 31, 2021, we decreased our total reserves related to prior period claims by $11.4 million. We will continue to assess ongoing developments, which may result in further adjustments to reserves.

Revenues increased by $443.8 million, or 29.7%, during the three months ended January 31, 2022, as compared to the three months ended January 31, 2021. This increase was primarily driven by a $307.7 million revenue increase due to the Able Acquisition in the fourth quarter of 2021, the recovery in volume of our business as Pandemic disruptions eased (primarily in Aviation and B&I), and new business within Aviation, M&D, and Technical Solutions. The increase in revenues was partially offset by a decrease in work orders for Pandemic-related demands (primarily in M&D).

Operating expenses increased by $410.2 million, or 32.8%, during the three months ended January 31, 2022, as compared to the three months ended January 31, 2021. Gross margin decreased by 200 bps to 14.3% in the three months ended January 31, 2022, from 16.3% in the three months ended January 31, 2021. The decrease in gross margin was primarily driven by the changes in contract mix due to decrease in cleaning services for Pandemic-related demands (primarily in B&I and M&D), which have higher margins, and the Able Acquisition. In addition, gross margin was also negatively impacted by an increase in direct labor and related costs (primarily in Education) due to the recovery in headcount as schools expanded capacity for in-person learning. The decrease was partially offset by lower self-insurance expense related to the prior periods, driven by improvement in the workers’ compensation program, reflecting reduced claim frequency related to the Pandemic and positive influences of claim closure projects and reserving practices.

Selling, general and administrative expenses increased by $30.5 million during the three months ended January 31, 2022, as compared to the three months ended January 31, 2021. The increase in selling, general and administrative expenses was primarily attributable to:

Amortization of intangible assets increased by $6.7 million, or 62.5%, during the three months ended January 31, 2022, as compared to the three months ended January 31, 2021. The increase was primarily due to the amortization of intangibles acquired as part of the Able Acquisition.

Interest expense decreased by $2.3 million, or 26.4%, during the three months ended January 31, 2022, as compared to the three months ended January 31, 2021, primarily due to lower relative interest rates in the current year as the result of amending our credit facility in the third quarter of fiscal year 2021.

Our effective tax rates from income on operations for the three months ended January 31, 2022, and January 31, 2021, were 24.2% and 26.7%, respectively, resulting in tax provisions of $24.3 million and $27.2 million, respectively.

During the three months ended January 31, 2022, interest rate swaps decreased by $0.6 million, or 51.1%, as compared to the three months ended January 31, 2021, primarily due to underlying changes in the fair value of our interest rate swaps.

We had a foreign currency translation loss of $2.4 million during the three months ended January 31, 2022, as compared to a foreign currency translation gain of $4.0 million during the three months ended January 31, 2021.
