in response to the continued spread of covid-19 , governmental authorities in the united states and around the world have imposed various restrictions designed to slow the pace of the pandemic , including restrictions on travel and other restrictions that prohibit employees from going to work , in cities where we have offices , employees , and customers causing severe disruptions in the worldwide economy , including the global demand for oil and natural gas . in response , companies within the energy industry ( including many of our customers ) have announced capital spending cuts which , in turn , may result in a decrease in new project awards or adjustments , reductions , suspensions , cancellations or payment defaults with respect to existing project awards . we have been fortunate that we entered 2020 with a robust backlog and that the larger projects in our backlog have not been cancelled or postponed . this has allowed us to keep a significant portion of our workforce productive . however , we have not been successful in replacing our backlog as quickly as it has been converted to revenues . as a result , our backlog has decreased by approximately $ 34.9 million from $ 59.2 million at december 28 , 2019 to $ 24.3 million at december 26 , 2020. while we have many potential opportunities in our sales pipeline that could replace a significant portion of this backlog reduction , inefficiencies and complications resulting from many of our clients ' remote working conditions combined with the uncertainty of new project necessity and funding caused by covid-19 related disruptions have largely contributed to delays in project awards and our inability to replace our backlog as quickly as it has been converted to revenue . while we believe our backlog is sufficient to keep a significant portion of our workforce productive in the near term , it may not be at our current operating levels . the extent to which the disruption of covid-19 may impact our business , financial condition and results of operations will depend on future developments , which are highly uncertain and can not be predicted at this time . the duration and intensity of these impacts and resulting disruption to our business , financial condition and results of operations is uncertain and we will continue to monitor the situation and assess the operational and financial impact on our business . as a result of these current and future uncertainties , we felt it necessary to utilize all avenues of available assistance as they may not be available in the future when needed . on april 13 , 2020 , we obtained a $ 4.9 million loan ( the “ ppp loan ” ) pursuant to the paycheck protection program ( the “ ppp ” ) under division a , title i of the coronavirus aid , relief , and economic security act ( “ cares act ” ) , which we expect to be forgiven . we are also utilizing relief for employees impacted by covid-19 under the families first coronavirus response act in order to minimize the impact to both our employees and our business . further , we are utilizing some of the tax payment deferral opportunities and federal refund acceleration opportunities provided by the irs and the cares act . on may 21 , 2020 , in order to provide additional liquidity , the company and its subsidiaries ( collectively , the “ borrowers ” ) entered into a loan and security agreement ( the “ revolving credit facility ” ) with pacific western bank dba pacific western business finance , a california state-chartered bank ( the “ lender ” ) , pursuant to which the lender agreed to extend credit to the borrowers in the form of revolving loans in the aggregate amount of up to $ 6.0 million , subject to a credit limit . for additional information , see “ liquidity and capital resources . ” as we continue to monitor the situation and assess the operational and financial impact on our business , we may determine to take further actions in response . 18 on june 27 , 2020 , we temporarily closed one of our operational facilities and sponsored covid-19 testing for employees in response to a potential covid-19 exposure . during the closure , we cleaned and sanitized the facility , and we reopened the facility after one week . employees and visitors were allowed to return to the facility only after negative test results were received or after a fourteen day quarantine period . although the closure was only for one week , the disruption to our operations was longer as testing results were received slower than expected and project progress was delayed . because the severity , magnitude and duration of the covid-19 pandemic and its economic consequences are uncertain , rapidly changing and difficult to predict , the impact on our business , financial condition and results of operations remains uncertain and difficult to predict . if covid–19 continues to spread or if the response to contain the covid-19 pandemic is unsuccessful , we could experience a material adverse effect on our business , financial condition , and results of operations . for additional information , see part ii . item 1a “ risk factors . ” results of operations our revenue is comprised of services revenue and the sale of engineered modular solutions . we generally recognize service revenue as soon as the services are performed . the majority of our engineering services have historically been provided through time-and-material contracts whereas a majority of our engineered modular solutions revenues are earned on fixed-price contracts . story_separator_special_tag selling , general and administrative – overall , our sg & a expenses decreased by $ 0.5 million for the year ended december 26 , 2020 as compared to the year ended december 28 , 2019. this decrease in sg & a is driven by reductions in travel costs due to covid-19 restrictions of $ 0.1 million , facility costs of $ 0.1 million , legal fees of $ 0.1 million , and $ 0.2 in computer software costs . we continue to look for ways to streamline our processes and delay expenditures while we continue to invest in our business development activities . 21 other income , net – other income , net of expense , decreased $ 35 thousand for the year ended december 26 , 2020 as compared to the year ended december 28 , 2019 primarily due to rental income received in 2019 with no comparable occurrence in 2020. tax expense – tax expense was $ 0.1 million for the year ended december 26 , 2020 and december 28 , 2019. net income ( loss ) – net loss for the year ended december 26 , 2020 was $ 0.6 million compared to a net loss of $ 1.5 million for the year ended december 28 , 2019 , primarily as a result of our increase in revenue and higher margin projects from our epcm segment and decrease in sg & a expense year-over-year , partially offset by project delays and inefficiencies due to the covid-19 pandemic . liquidity and capital resources overview we define liquidity as our ability to pay liabilities as they become due , fund business operations and meet monetary contractual obligations . our primary sources of liquidity are cash on hand , internally generated funds , and borrowings under the ppp loan and the revolving credit facility . our cash increased to $ 13.7 million at december 26 , 2020 from $ 8.3 million at december 28 , 2019 , as our operating activities used approximately $ 0.5 million in net cash during the year ended december 26 , 2020 primarily due to decreased contract assets net of contract liabilities , decreased accounts payable , and operating losses , partially offset by a decrease in trade receivables , depreciation and cash provided by other components of working capital . our working capital as of december 26 , 2020 was $ 14.0 million as compared to $ 11.3 million as of december 28 , 2019. on april 13 , 2020 , we obtained the ppp loan , which was a significant cash injection for us . in addition , on may 21 , 2020 , we entered into the revolving credit facility pursuant to which the lender agreed to extend credit of up to $ 6.0 million , subject to a credit limit . as of december 26 , 2020 , the credit limit under the revolving credit facility was $ 2.4 million and outstanding borrowings were $ 1.5 million , which yields enough interest to cover our minimum monthly interest charge . as of december 26 , 2020 , we were in compliance with all of the covenants under the ppp loan and revolving credit facility . for additional information on the ppp loan and revolving credit facility , see part ii , item 8 , note 7 – debt - . in addition , on january 29 , 2021 , we filed a shelf registration statement on form s-3 ( the “ registration statement ” ) with the sec , pursuant to which we may offer and sell , at our option , securities having an aggregate offering price of up to $ 100 million . on the same date , we entered into an at market issuance sales agreement with b. riley securities , inc. pursuant to which we may offer and sell shares of our common stock having an aggregate offering price of up to $ 25 million to or through b. riley , as sales agent , from time to time , in an “ at the market offering ” . the company is not obligated to make any sales under the agreement and any determination by the company to do so will be dependent , among other things , on market conditions and the company 's capital raising needs . the registration statement has not yet become effective and these securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective . we believe our cash on hand , internally generated funds and availability under the revolving credit facility along with other working capital will be sufficient to fund our current operations and expected activity for the next twelve months . cash and the availability of cash could be materially restricted if ( 1 ) outstanding invoices billed are not collected or are not collected in a timely manner , ( 2 ) circumstances prevent the timely internal processing of invoices , ( 3 ) we lose one or more of our major customers or our major customers significantly reduce the amount of work requested from us , ( 4 ) we are unable to win new projects that we can perform on a profitable basis or ( 5 ) we are unable to reverse our use of cash to fund losses . if any such event occurs , we would be forced to consider alternative financing options . our board of directors continues to review strategic transactions , which could include strategic mergers , reverse mergers , the issuance or buyback of public shares , or the purchase or sale of specific assets , in addition to other potential actions aimed at increasing shareholder value . the company does not intend to disclose or comment on developments related to its review unless and until the board has approved a specific transaction or otherwise determined that further disclosure is appropriate .
