The financial and business analysis below provides information which we believe
is relevant to an assessment and understanding of our financial position,
results of operations, and cash flows.  This financial and business analysis
should be read in conjunction with the financial statements and related notes.



In this section, we generally discuss the results of our operations for the year
ended December 31, 2019 compared to the year ended December 31, 2018. For a
discussion of the year ended December 31, 2018 to the year ended December 31,
2017, please refer to Part II, Item 7, "Management's Discussion and Analysis of
Financial Condition and Results of Operations" in our Annual Report on Form 10-K
for the year ended December 31, 2018, filed with the SEC on February 26, 2019,
which discussion is hereby incorporated herein by reference.



Executive Summary



We are a leading installer and distributor of insulation and other building
products to the U.S. construction industry.  Demand for our products and
services is driven primarily by residential new construction, commercial
construction, and residential repair/remodel activity throughout the U.S.  A
number of local and national factors influence activity in each of our lines of
business, including demographic trends, interest rates, employment levels,
business investment, supply and demand for housing stock, availability of
credit, foreclosure rates, consumer confidence, and general economic conditions.



Activity in the construction industry is seasonal, typically peaking in the summer months. Because installation of insulation historically lags housing starts by several months, we generally see a corresponding benefit in our operating results during the third and fourth quarters.

Strategy


Our long-term strategy is to grow net sales, net income, and operating cash flows and remain the leading insulation installer and distributor by revenue.

In order to achieve these goals, we plan to:

? Capitalize on the U.S. housing market through focused organic growth and

accretive aligned acquisitions

? Gain share in commercial construction

Continue to leverage our expertise in building science through our Environments

? for Living® program to benefit from the increasing focus on energy efficiency

and trends in building codes

? Grow our business through acquisitions of complementary businesses






Our operating results depend heavily on residential new construction activity
and, to a lesser extent, on commercial construction and residential
repair/remodel activity, all of which are cyclical.  We are also dependent on
third-party suppliers and manufacturers providing us with an adequate supply of
high-quality products.


Material Trends in Our Business





Housing starts (as reported by the U.S. Census Bureau) were lower than prior
year in the first half of 2019.  However, in the 3rd quarter housing starts
outpaced prior year by 3.9% and in the fourth quarter housing starts were 19.6%
higher than prior year.  This positive uptick in starts, combined with the
current low interest rate environment, is driving optimism for the housing
market for the year 2020.  We expect this industry tailwind in new residential
construction to be slightly tempered by a lower revenue per housing unit.  This
lower revenue per unit is being driven by higher multifamily starts vs.
single-family starts, and by the shift by homebuilders toward smaller, more
affordable, single-family units.



In 2019, we experienced strong growth vs. prior year in our sales to commercial
construction markets.  We expect these markets, both light and heavy commercial,
to remain strong in near-term with revenue in heavy commercial uneven due to
timing and the nature of these larger construction projects.



Seasonality



We normally experience stronger sales during the third and fourth calendar
quarters, corresponding with the peak season for residential new construction
and residential repair/remodel activity.  Sales during the winter weather months
are typically slower due to lower construction activity.  Historically, the
installation of insulation lags housing starts by several months.

Comparison of the Years Ended December 31, 2019 and December 31, 2018





Sales and Operations


Net sales for 2019 increased 10.1 percent, or $239.9 million, to $2.6 billion.

The increase was primarily driven by our USI acquisition in May 2018, increased volume, and by increased selling prices.





Our gross profit margin was 26.0 percent and 24.2 percent for 2019 and 2018,
respectively.  Gross profit margin improved primarily due to increased selling
prices, higher sales growth in our Installation segment vs. Distribution
segment, operational efficiencies, and synergies from the USI acquisition,
partially offset by higher material costs.



Selling, general, and administrative expense as a percentage of sales was 14.9
percent and 15.4 percent for 2019 and 2018, respectively.  Decreased selling,
general, and administrative expense as a percent of sales was primarily the
result of lower acquisition and closure costs related to the USI acquisition.



Operating margins were 11.0 percent and 8.8 percent for 2019 and 2018,
respectively.  The increase in operating margins related to increased selling
prices, increased sales volume, operational efficiencies, synergies from the USI
acquisition, and lower acquisition and closure costs related to the USI
acquisition, partially offset by higher material costs.



Other Expense, Net



Other expense, net, which primarily consists of interest expenses, increased
$7.6 million to $35.7 million in 2019 compared with 2018.  The increase is
primarily related to the issuance of our $400 million Senior Notes and our
borrowing of the $100 million delayed draw term loan to fund our acquisition of
USI in the second quarter of 2018, as well as the issuance of $15.0 million

of
equipment notes in 2019.

Income Tax Expense



Our effective tax rate decreased from 25.5 percent in 2018 to 24.7 percent in
2019.  The lower 2019 rate was primarily related to an increased benefit from
share-based compensation partially offset by an increase in the state and local
taxes.  The state and local tax increase was due to a revaluation of deferred
tax assets & liabilities resulting from state filing position changes, with some
offsetting benefit for the state return to provision adjustment and other
miscellaneous state adjustments.

    segments which is based on direct benefit or usage (such as salaries of
    corporate employees who directly support the segment).


    General corporate expense, net includes expenses not specifically

attributable to our segments for functions such as corporate human resources, (b) finance and legal, including salaries, benefits, and other related costs. In

the years ended December 31, 2019 and 2018, general corporate expense, net

decreased primarily due to merger and acquisition costs incurred related to


    the USI acquisition in 2018.



2019 and 2018 Business Segment Results Discussion

Changes in operating profit margins in the following business segment results discussion exclude general corporate expense, net in 2019 and 2018, as applicable.





Installation



Sales


Sales increased $225.8 million, or 13.4 percent, in 2019 compared to 2018.


 Sales increased 7.1 percent from acquisitions, 3.8 percent due to increased
selling prices, and 2.5 percent due to increased sales volume, primarily in

our
commercial markets.



                                       25



  Table of Contents

Operating Results



Operating margins in the Installation segment were 13.3 percent and 11.7 percent
for 2019 and 2018, respectively.  The increase in operating margins related to
increased selling prices, increased sales volume, operational efficiencies, and
synergies from the USI acquisition, partially offset by higher material costs.



Distribution



Sales



Sales increased $41.8 million, or 5.1 percent, in 2019 compared to 2018.  Sales
increased 4.6 percent due to increased selling prices, 1.3 percent from
acquisitions, and decreased 0.8 percent due to volume.  Volume decreased
primarily due to deliberate decisions with respect to price and volume, as well
as the decision to exit some low margin business.



Operating Results



Operating margins in the Distribution segment were 10.5 percent and 9.6 percent
for 2019 and 2018, respectively.  The increase in operating margins related to
increased selling prices and operational efficiencies, which were partially
offset by increased material costs.



Commitments and Contingencies



Litigation





We are subject to certain claims, charges, litigation, and other proceedings in
the ordinary course of our business, including those arising from or related to
contractual matters, intellectual property, personal injury, environmental
matters, product liability, product recalls, construction defects, insurance
coverage, personnel and employment disputes, antitrust, and other matters,
including class actions. We believe we have adequate defenses in these matters,
and we do not believe that the ultimate outcome of these matters will have a
material adverse effect on us.  However, there is no assurance that we will
prevail in any of these pending matters, and we could in the future incur
judgments, enter into settlements of claims, or revise our expectations
regarding the outcome of these matters, which could materially impact our
liquidity and our results of operations.



Other Commitments



We enter into contracts which include customary indemnities that are standard
for the industries in which we operate.  Such indemnities include, among other
things, customer claims against builders for issues relating to our products and
workmanship.  In conjunction with divestitures and other transactions, we
occasionally provide customary indemnities relating to various items including,
among others: the enforceability of trademarks; legal and environmental issues;
and asset valuations.  We evaluate the probability that we may incur liabilities
under these customary indemnities and appropriately record an estimated
liability when deemed probable.



We also maintain indemnification agreements with our directors and officers that
may require us to indemnify them against liabilities that arise by reason of
their status or service as directors or officers, except as prohibited by
applicable law.



We occasionally use performance bonds to ensure completion of our work on certain larger customer contracts that can span multiple accounting periods.


 Performance bonds generally do not have stated expiration dates; rather, we are
released from the bonds as the contractual performance is completed.  We also
have bonds outstanding for license and insurance.  For additional information
see Item 8. Financial Statements and Supplementary Data - Note 11. Other
Commitments and Contingencies.

Liquidity and Capital Resources


We have access to liquidity through our cash from operations and available
borrowing capacity under our Amended Credit Agreement, which provides for
borrowing and/or standby letter of credit issuances of up to $250 million under
the Revolving Facility.  For additional information regarding our outstanding
debt and borrowing capacity see Item 8. Financial Statements and Supplementary
Data - Note 6. Long-Term Debt.  We believe that our cash flows from operations,
combined with our current cash levels and available borrowing capacity, will be
adequate to support our ongoing operations and to fund our debt service
requirements, capital expenditures, and working capital for at least the next
twelve months.  Cash flows are seasonally stronger in the third and fourth
quarters as a result of increased new construction activity during those
periods.

Net cash flows provided by operating activities increased $104.6 million for the
year ended December 31, 2019, as compared to December 31, 2018.  The increase
was primarily due to an increase in net income, the timing of working capital
collections and expenditures, and the timing of income tax payments.



Net cash used in investing activities was $50.1 million for the year ended
December 31, 2019, primarily comprised of $45.5 million for purchases of
property and equipment, primarily vehicles, and $7.0 million for acquisitions,
and partially offset by $2.3 million of proceeds from the sale of property and
equipment.  Net cash used in investing activities was $551.8 million for the
year ended December 31, 2018, primarily comprised of $500.2 million of net cash
for the acquisition of USI and ADO and substantially all of the assets of Santa
Rosa, and $52.5 million for purchases of property and equipment primarily
vehicles, partially offset by $0.8 million of proceeds from the sale of

property and equipment.

Net cash used in financing activities was $137.8 million for the year ended
December 31, 2019. We used $110.9 million for common stock repurchases related
to our share repurchase programs, including $50.0 million under the 2019 ASR
Agreement, $21.9 million for payments on our term loan, $13.0 million for
purchases of common stock for tax withholding obligations related to the vesting
and exercise of share-based incentive awards, $5.9 million for payments on our
equipment financing notes, and $1.1 million for payments of contingent
consideration for EcoFoam and Santa Rosa. We received $15.0 million of proceeds
from equipment financing notes.  Net cash provided by financing activities was
$429.1 million for the year ended December 31, 2018. In 2018, we received $400.0
million from the issuance of our Senior Notes and $100.0 million from the
delayed draw on our term loan which we used to fund our acquisition of USI. We
received $26.6 million of proceeds from equipment financing notes related to our
decision to begin purchasing rather than leasing vehicles. We used $65.0 million
for common stock repurchases related to our share repurchase programs, including
$50.0 million under the 2018 ASR Agreement, $16.3 million for payments on our
term loan, $7.8 million for payment of debt issuance costs related to our
Amended Credit Agreement and our Senior Notes, $5.5 million for purchases of
common stock for tax withholding obligations related to the vesting and exercise
of share-based incentive awards, and $2.1 million for payments on our equipment
financing notes. We also made a payment of $0.8 million of contingent
consideration for EcoFoam. We drew $90.0 million on our Revolving Facility

and
repaid $90.0 million

Critical Accounting Policies and Estimates


We prepare our Consolidated Financial Statements in conformity with GAAP.  The
preparation of these financial statements requires us to make estimates and
assumptions that affect the reported amounts of assets and liabilities, and
disclosure of contingent assets and liabilities, at the date of the financial
statements, and the reported amounts of sales and expenses during the reporting
period.  Actual results could differ from those estimates.



Our significant accounting policies are more fully described in Item 8.
Financial Statements and Supplementary Data - Note 1. Summary of Significant
Accounting Policies.  However, certain of our accounting policies considered
critical are those we believe are both most important to the portrayal of our
financial condition and operating results and require our most difficult,
subjective, or complex judgments, often as a result of the need to make
estimates about the effect of matters that are inherently uncertain.  Judgments
and uncertainties affecting the application of those policies may result in
materially different amounts being reported under different conditions or using
different assumptions.  We consider the following policies to be most critical
in understanding the judgments that are involved in preparing our Consolidated
Financial Statements.


Revenue Recognition and Receivables


We recognize revenue for our Installation segment over time as the related
performance obligation is satisfied with respect to each particular order within
a given customer's contract. Progress toward complete satisfaction of the
performance obligation is measured using a cost-to-cost measure of progress
method. The cost input is based on the amount of material installed at that
customer's location and the associated labor costs, as compared to the total
expected cost for the particular order.   Revenue is recognized as the customer
is able to receive and utilize the benefits provided by our services. Each
contract contains one or more individual orders, which are based on services
delivered. When a contract modification is made, typically the remaining goods
or services are considered distinct and we recognize revenue for the
modification as a separate performance obligation. When material and
installation services are bundled in a contract, we combine these items into one
performance obligation as the overall promise is to transfer the combined item.



Revenue from our Distribution segment is recognized when title to products and
risk of loss transfers to our customers.  This represents the point in time when
the customer is able to direct the use of and obtain substantially all the
benefits from the product. The determination of when control is deemed
transferred depends on the shipping terms that are agreed upon in the contract.

                                       28



  Table of Contents



At time of sale, we record estimated reductions to revenue for customer programs
and incentive offerings, including special pricing and other volume-based
incentives based on historical experience, which is continuously adjusted. The
duration of our contracts with customers is relatively short, generally less
than a 90-day period, and therefore there is not a significant financing
component when considering the determination of the transaction price which gets
allocated to the individual performance obligations, generally based on
standalone selling prices. Additionally, we consider shipping costs charged to a
customer as a fulfillment cost rather than a promised service and expense as
incurred. Sales taxes, when incurred, are recorded as a liability and excluded
from revenue on a net basis.



We record a contract asset when we have satisfied our performance obligation
prior to billing and a contract liability when a customer payment is received
prior to the satisfaction of our performance obligation. The difference between
the beginning and ending balances of our contract assets and liabilities
primarily results from the timing of our performance and the customer's payment.



We maintain allowances for doubtful accounts receivable for estimated losses
resulting from the inability of customers to make required payments.  In
addition, we monitor our customer receivable balances and the credit worthiness
of our customers on an on-going basis.  During downturns in our markets,
declines in the financial condition and creditworthiness of customers impact the
credit risk of the receivables involved and we have incurred additional bad debt
expense related to customer defaults.



Goodwill and Other Intangible Assets





We have two reporting units, which are also our operating and reporting
segments: Installation and Distribution. Both reporting units contain goodwill.
Assets acquired and liabilities assumed are assigned to the applicable reporting
unit based on whether the acquired assets and liabilities relate to the
operations of and determination of the fair value of such unit. Goodwill
assigned to the reporting unit is the excess of the fair value of the acquired
business over the fair value of the individual assets acquired and liabilities
assumed for the reporting unit.



We perform our annual impairment testing of goodwill in the fourth quarter of
each year, or as events occur or circumstances change that would more likely
than not reduce the fair value of a reporting unit below its carrying amount.
 When assessing goodwill for impairment, we have the option to first assess
qualitative factors to determine whether the existence of events or
circumstances leads to a determination that it is more likely than not that the
fair value of a reporting unit is less than its carrying amount.  If, after
assessing the totality of events or circumstances, we determine it is more
likely than not that the fair value of a reporting unit is less than its
carrying amount, then we perform a two-step impairment test.  If we conclude
otherwise, then no further action is taken.



We also have the option to bypass the qualitative assessment and only perform a
quantitative assessment, which is the first step of the two-step impairment
test.  In completing the two-step impairment test, we complete the impairment
testing utilizing a discounted cash flow method.  We selected this methodology
because we believe that it is comparable to what would be used by other market
participants.  Our operating segments are reporting units that engage in
business activities for which discrete financial information, including long
range forecasts, is available.  We have identified our segments as our reporting
units and complete the impairment testing of goodwill at the operating segment
level, as defined by accounting guidance.  Fair value for our reporting units is
determined using a discounted cash flow method which includes significant
unobservable inputs (Level 3 inputs).



Determining market values using a discounted cash flow method requires us to
make significant estimates and assumptions, including long term projections of
cash flows, market conditions, and appropriate discount rates.  Our judgments
are based on historical experience, current market trends, consultations with
external valuation specialists, and other information.  While we believe that
the estimates and assumptions underlying the valuation methodology are
reasonable, changes to estimates and assumptions could result in different
outcomes.  In estimating future cash flows, we rely on internally generated long
range forecasts for sales and operating profits, and generally a one to three
percent long term assumed annual growth rate of cash flows for periods after the
long range forecast.  We generally develop these forecasts based upon, among
other things, recent sales data for existing products, and estimated U.S.
housing starts.

When necessary, an impairment loss is recognized to the extent that a reporting
unit's recorded goodwill exceeds its implied fair value.  We did not recognize
any impairment charges for goodwill for the years ended December 31, 2019, 2018,
and 2017.  As of December 31, 2019, net goodwill reflected $762.0 million of
accumulated impairment losses, relating primarily to impairment charges taken in
2008-2010 following the substantial decrease in U.S. housing starts after the
financial crisis of 2007-2008.



In the fourth quarter of 2019, we performed an assessment on our goodwill and
determined that the estimated fair value of each reporting unit substantially
exceeded its carrying value at December 31, 2019, and therefore the goodwill was
not impaired.  In the fourth quarter of 2018, we performed an assessment on our
goodwill and concluded that it was more-likely-than-not that goodwill was not
impaired.



Intangible assets with finite useful lives are amortized using the straight-line
method over their estimated useful lives.  We evaluate the remaining useful
lives of amortizable identifiable intangible assets at each reporting period to
determine whether events and circumstances warrant a revision to the remaining
periods of amortization.



Income Taxes



If, based upon all available evidence, both positive and negative, it is more
likely than not (more than 50 percent likely) such deferred tax assets will not
be realized, a valuation allowance is recorded.  Significant weight is given to
positive and negative evidence that is objectively verifiable.  A company's
three year cumulative loss position is significant negative evidence in
considering whether deferred tax assets are realizable and the accounting
guidance restricts the amount of reliance we can place on projected taxable
income to support the recovery of deferred tax assets.



Current accounting guidance allows the recognition of only those income tax
positions that have a greater than 50 percent likelihood of being sustained upon
examination by taxing authorities.  We believe that there is an increased
potential for volatility in our effective tax rate because this threshold allows
changes in the income tax environment and the inherent complexities of income
tax law in a substantial number of jurisdictions to affect the computation of
the liability for uncertain tax positions to a greater extent.



While we believe we have adequately assessed for our uncertain tax positions,
amounts asserted by taxing authorities could vary from our assessment of
uncertain tax positions.  Accordingly, provisions for tax-related matters,
including interest and penalties, could be recorded in income tax expense in the
period revised assessments are made.



Business Combinations



The purchase price for business combinations is allocated to the estimated fair
values of acquired tangible and intangible assets, including goodwill, and
assumed liabilities, where applicable.  Management uses significant judgments
involving estimates and assumptions when determining the fair value of assets
acquired and liabilities assumed. These estimates include, but are not limited
to, discount rates, projected future revenue growth, cost synergies and expected
cash flows, customer attrition rates, useful lives, and other prospective
financial information. Additionally, we recognize customer relationships,
trademarks and trade names, and non-competition agreements as identifiable
intangible assets, which are recorded at fair value as of the transaction date.
 The fair value of these intangible assets is determined primarily using the
income approach and using current industry information.  Goodwill is recorded
when consideration transferred exceeds the fair value of identifiable assets and
liabilities.  Measurement-period adjustments to assets acquired and liabilities
assumed with a corresponding offset to goodwill are recorded in the period they
occur, which may include up to one year from the acquisition date.  Contingent
consideration is recorded at fair value at the acquisition date.
