Commitments and Contingencies Disclosure [Abstract]

Bond commitments

In the ordinary course of business, predominantly in the Architectural Services and Architectural Framing Systems segments, we are required to provide surety or performance bonds that commit payments to our customers for any non-performance. At February 29, 2020, $913.9 million of these types of bonds were outstanding, of which, $487.5 million is on our backlog. These bonds do not have stated expiration dates, as we are released from the bonds upon completion of the contract. We have never been required to make payments under surety or performance bonds with respect to our existing businesses.

Warranty and project-related contingencies

We reserve estimated exposures on known claims, as well as on a portion of anticipated claims, for product warranty and rework costs based on historical product liability claims as a ratio of sales. Claim costs are deducted from the accrual when paid. Factors that could have an impact on the warranty accrual in any given period include the following: changes in manufacturing quality, changes in product mix and any significant changes in sales volume. A warranty rollforward follows:



(In thousands)	2020			2019
Balance at beginning of period	$	16,737		$	22,517
Additional accruals	8,224			5,552
Claims paid	(9,332		)	(11,332		)
Balance at end of period	$	15,629		$	16,737

Additionally, we are subject to project management and installation-related contingencies as a result of our fixed-price material supply and installation service contracts, primarily in our Architectural Services segment and certain of our Architectural Framing Systems businesses. We manage the risk of these exposures through contract negotiations, proactive project management and insurance coverages. The liability for these types of project-related contingencies was $49.0 million and $42.1 million as of February 29, 2020 and March 2, 2019, respectively. During fiscal 2020, we received $15.0 million of insurance proceeds related to a project matter, which was included within cost of sales on our consolidated results of operations.

Letters of credit

At February 29, 2020, we had $24.7 million of ongoing letters of credit, all of which have been issued under our revolving credit facility, as discussed in Note 8.

Purchase obligations

Purchase obligations for raw material commitments and capital expenditures totaled $170.4 million as of February 29, 2020.

Environmental liability

In fiscal 2008, we acquired one manufacturing facility which has certain historical environmental conditions. Remediation of these conditions is ongoing without significant disruption to our operations. The estimated remaining liability for these remediation activities was $0.7 million and $1.2 million at February 29, 2020 and March 2, 2019, respectively.

New Markets Tax Credit (NMTC) transactions

We have entered into four separate NMTC programs to support our operational expansion, including two transactions completed in fiscal 2019. Proceeds received from investors on these transactions are included within other current and non-current liabilities on our consolidated balance sheets. The NMTC arrangements are subject to 100 percent tax credit recapture for a period of seven years from the date of each respective transaction. Therefore, upon the termination of each arrangement, these proceeds will be recognized in earnings in exchange for the transfer of tax credits. The direct and incremental costs incurred in structuring these arrangements have been deferred and are included in other current and non-current assets on our consolidated balance sheets. These costs will be recognized in conjunction with the recognition of the related proceeds on each arrangement. During the

construction phase, we are required to hold cash dedicated to fund each capital project which is classified as restricted cash on our consolidated balance sheets. Variable-interest entities, which have been included within our consolidated financial statements, have been created as a result of the structure of these transactions, as investors in the programs do not have a material interest in their underlying economics.

The table below provides a summary of our outstanding NMTC transactions (in millions):



Inception date	Termination date	Proceeds received		Deferred costs		Net benefit
November 2013	November 2020	$	10.7	$	3.3	$	7.4

Litigation

On November 5, 2018, a shareholder filed a purported securities class action against the Company and certain named executive officers. On April 26, 2019, the new lead plaintiff filed an amended complaint, alleging that, during the purported class period of May 1, 2017 to April 10, 2019, the Company and the named executive officers made materially false or misleading statements or omissions about the Company's acquisition of EFCO Corporation on June 12, 2017, and about the Company's Architectural Glass business segment, in violation of the federal securities laws. On March 25, 2020, the District Court granted the Company's motion to dismiss without prejudice this matter.

On December 17, 2018, a different shareholder filed a derivative lawsuit, purportedly on behalf of the Company, against certain of our executive officers and directors claiming breaches of fiduciary duty, waste of corporate assets and unjust enrichment. This complaint alleges that the officers and directors allegedly made materially false or misleading statements or omissions about the Company's business, operations and prospects, particularly with respect to our Architectural Glass business segment, during the period between June 28, 2018 and September 17, 2018. This matter has been stayed, pending resolution of a motion to dismiss the foregoing matter. We intend to vigorously defend this matter.

In addition to the foregoing, the Company is a party to various legal proceedings incidental to its normal operating activities. In particular, like others in the construction supply and services industry, the Company is routinely involved in various disputes and claims arising out of construction projects, sometimes involving significant monetary damages or product replacement. The Company is also subject to litigation arising out of areas such as employment practices, workers compensation and general liability matters. Although it is very difficult to accurately predict the outcome of any such proceedings, facts currently available indicate that no matters will result in losses that would have a material adverse effect on the results of operations, cash flows or financial condition of the Company.
