The following discussion and analysis includes forward-looking statements about
the Company's business and consolidated results of operations for the three
months ended March 31, 2022 and 2021, including discussions about management's
expectations for the Company's business. These statements represent projections,
beliefs and expectations based on current circumstances and conditions and are
made in light of recent events and trends. These statements should not be
construed either as assurances of performance or as promises of a given course
of action. Instead, various known and unknown factors are likely to cause the
Company's actual performance and management's actions to vary, and the results
of these variances may be both material and adverse. See "Forward-Looking
Statements." The following discussion should also be read in conjunction with
the Company's unaudited consolidated financial statements and the related Notes
included in this Quarterly Report.

Executive Overview



The Company designs, engineers, manufactures, markets and sells a broad range of
advanced, emission-certified engines and power systems that run on a wide
variety of clean, alternative fuels, including natural gas, propane, and
biofuels, as well as gasoline and diesel options, within the power systems,
industrial and transportation end markets with primary manufacturing, assembly,
engineering, research and development ("R&D"), sales and distribution facilities
located in suburban Chicago, Illinois and Darien, Wisconsin. The Company
provides highly engineered, comprehensive solutions designed to meet specific
customer application requirements and technical specifications, including those
imposed by environmental regulatory bodies, such as the U.S. Environment
Protection Agency ("EPA"), the California Air Resource Board ("CARB") and the
People's Republic of China's Ministry of Ecology and Environment ("MEE").

The Company's products are primarily used by global original equipment
manufacturers ("OEM") and end-user customers across a wide range of applications
and equipment that includes standby and prime power generation, demand response,
microgrid, combined heat and power, arbor care, material handling (including
forklifts), agricultural and turf, construction, pumps and irrigation,
compressors, utility vehicles, light- and medium-duty vocational trucks, school
and transit buses, and utility power. The Company manages the business as a
single reporting segment.

For the three months ended March 31, 2022, the Company's net sales decreased
$1.2 million, or 1%, from the three months ended March 31, 2021 to $98.9
million, as a result of a sales decline of $25.8 million in the transportation
end market, partly offset by increases of $13.1 million and $11.5 million in the
power systems and industrial end markets, respectively. Gross margin for the
three months ended March 31, 2022 was 16.9%, a improvement versus 7.1% in the
comparable 2021 period. Gross profit increased $9.6 million for the three months
ended March 31, 2022, while operating expenses decreased by $6.2 million, as
compared to the comparable period in 2021. Interest expense increased by $0.3
million for the three months ended March 31, 2022 versus the comparable period
in 2021. Also, the Company recorded income tax expense of $0.4 million for both
the three months ended March 31, 2022 and March 31, 2021, respectively.
Collectively, these factors contributed to a $15.6 million decrease in the net
loss, which totaled $2.6 million in the 2022 period compared to a net loss of
$18.2 million in the same period of 2021. Diluted loss per share was $0.11 in
the 2022 period compared to a diluted loss per share of $0.79 in the comparable
2021 period. Adjusted net loss, which excludes certain items described below
that the Company believes are not indicative of its ongoing operating
performance, was $0.9 million in the 2022 period, an improvement of $12.1
million, compared to an Adjusted net loss of $13.0 million in 2021. Adjusted
loss per share was $0.03 in 2022 compared to an Adjusted loss per share of $0.56
in 2021. Adjusted earnings before interest expense, income taxes, depreciation
and amortization ("EBITDA") was positive at $3.7 million in 2022 compared to an
Adjusted EBITDA loss of $8.5 million in 2021. Adjusted net (loss) income,
Adjusted earnings (loss) per share and Adjusted EBITDA are non-GAAP financial
measures. For a reconciliation of each of these measures to the nearest
applicable GAAP financial measure, as well as additional information about these
non-GAAP measures, see the section entitled Non-GAAP Financial Measures in this
Item 2.

Recent Trends and Business Outlook

COVID-19 Update and Oil and Gas Market Volatility



The COVID-19 pandemic has resulted in the implementation of significant
governmental measures to control the spread of the virus, including quarantines,
travel restrictions, business shutdowns, and restrictions on the movement of
people in the United States and abroad. These factors, in turn, have impacted
and may continue to impact the Company's operations, financial condition, and
demand for its goods and services, as well as its overall ability to react
timely to mitigate any further impact of the COVID-19 pandemic.

As of the date of this Form 10-Q, the Company continues to judiciously manage
its expenses through the continuation of certain measures, including the
restriction of all non-essential travel and minimized discretionary expenses and
consulting services. The Company continues to review operating expenses,
including prioritizing certain R&D investments in support of the Company's
long-term growth objectives. During 2021, the Company took rightsizing actions
to align its staffing with current needs, while also streamlining certain roles.
These actions, when coupled with attrition, contributed to the reduction of
approximately 100 positions, or approximately 12.5% of the Company's headcount.
Also, the Company continues to review its facilities footprint in light of its
current and planned business mix and its evolving needs. To date, these efforts
resulted in the exit and sublease of its Hanover Park, IL materials and
warehousing facility which is expected to generate annualized savings of
approximately $1.3 million, with approximately $0.9 million expected to be
realized in 2022.

The full impact of the COVID-19 pandemic continues to evolve as of the date of this Form 10-Q.



During 2020 and 2021, as a result of the COVID-19 pandemic, the global economy
experienced substantial turmoil, which led to challenging market conditions
across certain areas of the Company's business. In addition, due to
unprecedented decreases in demand, an oil price war, and economic uncertainty
resulting from the COVID-19 pandemic, average crude oil prices were considerably
lower in 2020 as compared to prices at the end of 2019 but showed signs of
improvement in 2021 and through the first quarter of 2022. However, although rig
counts in the U.S. oil markets increased during 2021 and through the first
quarter of 2022, average rig counts remained below pre-pandemic levels. The
Company also believes that capital spending within the U.S. oil and gas industry
remains well below pre-pandemic levels. While the Company saw an increase of
sales to customers with traditional exposure to the oil and gas markets during
the first quarter of 2022, as compared to the prior year, sales remain below
2019 levels. A significant portion of the Company's sales and profitability has
historically been derived from the sale of products that are used within the oil
and gas industry. In addition, the Company continued to experience delays in its
supply chain during the first quarter of 2022 due to temporary shortages of raw
materials and container delays of overseas materials as bottlenecks occurred at
ports in Asia and North America. This, in turn, caused delivery delays to some
of the Company's customers. The Company also experienced inflationary cost
pressures for certain materials and shipping-related costs. Additionally, the
Company continues to experience ongoing tariff costs for products that did not
receive exclusions. The Company is working to mitigate the impact of these
matters through price increases and other measures, such as seeking certain
tariff exclusions, where possible. The potential for continued disruptions,
economic uncertainty, and unfavorable oil and gas market dynamics may have a
material adverse impact on the timing of delivery of customer orders and the
levels of future customer orders.

Lastly, during 2021, the Company incurred significantly higher legal costs due
to its obligation to indemnify certain former officers and employees as a result
of exhaustion of its directors and officers insurance during the early part of
2020. In particular, spending activity was elevated during the first nine months
of 2021 as a result of the USAO trial involving former officers and employees of
the Company. With a verdict reached in the USAO trial matter involving former
officers and employees in September 2021, the Company believes its costs related
to the matter will cease. Accordingly, the Company saw a substantial decline in
these costs during the first quarter of 2022. However, at this time, the Company
is not able to estimate the potential future amount of its indemnity obligations
related to the pending SEC matter involving prior officers and employees. See
Note 9. Commitments and Contingencies, included in Part 1, Item 1. Financial
Statements, for further discussion of the Company's indemnification obligations.
Accordingly, the above challenges may continue to have a material adverse impact
on the Company's future results of operations, financial position, and
liquidity.

--------------------------------------------------------------------------------

Net Sales



Net sales decreased $1.2 million, or 1%, during the three months ended March 31,
2022 compared to the three months ended March 31, 2021, as a result of a sales
decline of $25.8 million in the transportation end market, partly offset by
increases of $13.1 million and $11.5 million in the power systems and industrial
end markets, respectively. Further, overall sales in the first quarter of 2022
continued to reflect supply chain challenges that impacted the Company's ability
to timely meet certain orders. The decreased sales within the transportation end
market were primarily attributable to lower sales in the medium duty truck
market, coupled with lower demand for school bus products. Higher power systems
end market sales were primarily due to increased sales of power generation
products, particularly to customers serving the demand response markets and to
customers with traditional exposure to the oil and gas markets. Higher
industrial end market sales are primarily due to increased demand for products
across various applications, with the largest increase attributable to products
used within the material handling/forklift market.

Gross Profit



Gross profit increased by $9.6 million, or 136%, during the three months ended
March 31, 2022 as compared to the three months ended March 31, 2021. Gross
margin was 16.9% during the three months ended March 31, 2022, an increase of
9.8 percentage points compared to 7.1% for the three months ended March 31,
2021, primarily due to lower warranty expense, among other items. For the three
months ended March 31, 2022, warranty costs were a benefit of $0.3 million, a
change of $7.1 million compared to warranty costs of $6.8 million last year, due
largely to favorable adjustments to preexisting warranties during the first
quarter of 2022. A majority of the warranty activity is attributable to products
sold within the transportation end market.

Research, Development and Engineering Expenses



Research, development and engineering expenses during the three months ended
March 31, 2022 were $4.6 million, a decrease of $1.7 million, or 27%, from the
three months ended March 31, 2021, due to lower wages and benefits driven by
reduced headcount and lower project activity in the current quarter versus the
prior year.

Selling, General and Administrative Expenses



Selling, general and administrative ("SG&A") expenses decreased during the three
months ended March 31, 2022 by $4.4 million, or 28%, compared to the three
months ended March 31, 2021, primarily due to lower legal costs related to the
Company's indemnification obligations of former officers and employees driven
largely by the conclusion of the USAO trial involving former officers and
employees during September 2021. (see additional discussion in Note 9.
Commitments and Contingencies in Part I. Item 1. Financial Statements for
further discussion). The Company also experienced lower wages and benefits
expense, due in part to reduced incentive compensation expense, and also had
lower financial reporting fees.

Interest Expense



Interest expense increased $0.3 million to $2.4 million for the three months
ended March 31, 2022 as compared to the three months ended March 31, 2021, due
in part to higher outstanding debt levels during the current quarter versus the
prior year. See Note 6. Debt, included in Part 1, Item 1. Financial Statements,
for additional information.

Income Tax Expense



The Company recorded income tax expense of $0.4 million for both the three
months ended March 31, 2022 and 2021, respectively. The Company's pretax loss
was $2.2 million for the three months ended March 31, 2022, compared to a pretax
loss of $17.8 million for the three months ended March 31, 2021. The Company
continues to record a full valuation allowance against deferred tax assets which
offsets the tax benefits otherwise associated with the pre-tax losses for the
three months ended March 31, 2022 and 2021. See Note 10. Income Taxes, included
in Part 1, Item 1. Financial Statements, for additional information related to
the Company's income tax provision.


Non-GAAP Financial Measures



In addition to the results provided in accordance with accounting principles
generally accepted in the United States ("U.S. GAAP") above, this report also
includes non-GAAP (adjusted) financial measures. Non-GAAP financial measures
provide insight into selected financial information and should be evaluated in
the context in which they are presented. These non-GAAP financial measures have
limitations as analytical tools and should not be considered in isolation from,
or as a substitute for, financial information presented in compliance with U.S.
GAAP, and non-GAAP financial measures as reported by the Company may not be
comparable to similarly titled amounts reported by other companies. The non-GAAP
financial measures should be considered in conjunction with the consolidated
financial statements, including the related notes, and Management's Discussion
and Analysis of Financial Condition and Results of Operations included in this

purpose other than the reasons stated below.

The Company believes that Adjusted net income (loss), Adjusted earnings (loss)
per share, EBITDA, and Adjusted EBITDA provide relevant and useful information,
which is widely used by analysts, investors and competitors in its industry as
well as by the Company's management in assessing the performance of the Company.
Adjusted net income (loss) is defined as net income (loss) as adjusted for
certain items that the Company believes are not indicative of its ongoing
operating performance. Adjusted earnings (loss) per share is a measure of the
Company's diluted earnings (loss) per common share adjusted for the impact of
special items. EBITDA provides the Company with an understanding of earnings
before the impact of investing and financing charges and income taxes. Adjusted
EBITDA further excludes the effects of other non-cash charges and certain other
items that do not reflect the ordinary earnings of the Company's operations.

Adjusted net income (loss), Adjusted earnings (loss) per share, EBITDA, and
Adjusted EBITDA are used by management for various purposes, including as a
measure of performance of the Company's operations and as a basis for strategic
planning and forecasting. Adjusted net income (loss), Adjusted earnings (loss)
per share, and Adjusted EBITDA may be useful to an investor because these
measures are widely used to evaluate companies' operating performance without
regard to items excluded from the calculation of such measures, which can vary
substantially from company to company depending on the accounting methods, the
book value of assets, the capital structure and the method by which the assets
were acquired, among other factors. They are not, however, intended as
alternative measures of operating results or cash flow from operations as
determined in accordance with U.S. GAAP.

Company. The Company is obligated to pay legal costs of certain former officers
and employees in accordance with Company bylaws and certain indemnification
agreements. As further discussed in Note 9. Commitments and Contingencies of
Part I, Item 1. Financial Statements, the Company fully exhausted its historical
primary directors' and officers' insurance coverage in connection with these
matters during the first quarter of 2020. Also included are professional

Cash Flows for the Three Months Ended March 31, 2022

Cash Flow from Operating Activities


                                       30

--------------------------------------------------------------------------------

Net cash used in operating activities was $17.4 million in the three months
ended March 31, 2022 compared to net cash provided by operating activities of
$5.7 million in the three months ended March 31, 2021, resulting in an increase
of $23.1 million in cash used in operating activities year-over-year. The
increase in cash used by operating activities was primarily related to a
decrease in the net loss of $15.6 million, offset by a $38.0 million decrease in
cash generated from working capital accounts, and a $0.6 million decline in
non-cash adjustments. The decrease in cash generated from working capital in the
three months ended March 31, 2022 compared to the three months ended March 31,
2021 was primarily related to lower accounts receivable collections and a net
decrease in liabilities, partly offset by a decrease in cash outflows associated
with inventory purchases. The net decrease in liabilities was largely due to
decreased accounts payable due to the timing of management of payables and a
decrease in other non current liabilities, partly offset by an increase in other
current liabilities. The decrease in non-cash adjustments was primarily due to
decreased amortization of deferred financing fees.

Cash Flow from Investing Activities



Net cash used in investing activities was $0.1 million for the three months
ended March 31, 2022 compared to cash used in investing activities of $0.6
million for the three months ended March 31, 2021. For the three months ended
March 31, 2022 and 2021, cash used in investing activities primarily related to
capital expenditures associated with normal maintenance of the Company's
facilities.

Cash Flow from Financing Activities



The Company generated $13.2 million in cash from financing activities in the
three months ended March 31, 2022 compared to $2.6 million in cash used by
financing activities in the three months ended March 31, 2021. The cash
generated by financing activities for the three months ended March 31, 2022 was
primarily attributable to cash received under the shareholder's loan agreement
with Weichai, compared to no new borrowings for the three months ended March 31,
2021. See additional discussion below and in Note 6. Debt, included in Part I,
Item 1. Financial Statements related to the amendments of the Company's debt
arrangements.

Liquidity and Capital Resources



On March 25, 2022, the Company amended and restated its $130.0 million
uncommitted senior secured revolving credit agreement with Standard Chartered by
entering (the "Second Amended and Restated Credit Agreement"). The Second
Amended and Restated Credit Agreement extends the maturity date of loans
outstanding under its previous credit facility to the earlier of March 24, 2023
or the demand of Standard Chartered. The Second Amended and Restated Credit
Agreement is subject to customary events of default and covenants, including
minimum consolidated EBITDA and Consolidated Interest Coverage Ratio covenants
for the second and third quarters of 2022. Borrowings under the Second Amended
and Restated Credit Agreement will incur interest at either the alternate base
rate or the SOFR plus 2.95% per annum. The Second Amended and Restated Credit
Agreement continues to be secured by substantially all of the Company's assets
and provides Standard Chartered the right to demand payment of any and all of
the outstanding borrowings and other amounts owed under the Second Amended and
Restated Credit Agreement at any point in time prior to the maturity date at
Standard Chartered's discretion. Furthermore, the Second Amended and Restated
Credit Agreement grants Standard Chartered a power of attorney (POA) to submit a
borrowing request to Weichai under the Amended First Shareholder's Loan
Agreement (see discussion below) if the Company did not submit a borrowing
request to Weichai within five business days of receiving a request from
Standard Chartered to submit said borrowing request. As of March 31, 2022, the
Company had $130.0 million outstanding under the Second Amended and Restated
Credit Agreement.

In connection with the Second Amended and Restated Credit Agreement, on March
25, 2022, the Company also amended two of its shareholder's loan agreements with
Weichai, to among other things, extend the maturities thereof. The amended first
shareholder's loan agreement (the "Amended First Shareholder's Loan Agreement")
continues to provide the Company with a $130.0 million subordinated loan under
which Weichai is obligated to advance funds solely for purposes of repaying
outstanding borrowings under the Second Amended and Restated Credit Agreement if
the Company is unable to pay such borrowings. The amended second shareholder's
loan agreement (the "Amended Second Shareholder's Loan Agreement") continues to
provide the Company with a $25.0 million subordinated loan at the discretion of
Weichai. The maturity of the Amended First Shareholder's Loan Agreement was
extended to April 24, 2023 and the maturity of the Amended Second Shareholder's
Loan Agreement was extended to May 20, 2023. The Company has covenanted to
secure any amounts borrowed under either of the agreements upon payment in full
of all amounts outstanding under the Second Amended and Restated Credit
Agreement. As of March 31, 2022, there were no borrowings under the Amended
First Shareholder's Loan Agreement and $25.0 million under the Amended Second
Shareholder's Loan Agreement.

The Company is also party to the third shareholder's loan agreement with
Weichai, which was entered into on December 10, 2021 (the "Third Shareholder's
Loan Agreement"). The Third Shareholder's Loan Agreement provides the Company
with a $50.0 million uncommitted facility that is subordinated to the Second
Amended and Restated Credit Agreement and any borrowing requests made under the
Third Shareholder's Loan Agreement are subject to Weichai's discretionary
approval. Borrowings under the Third Shareholder's Loan Agreement bear interest
at LIBOR plus 4.50% and can be used for general

                                       31

--------------------------------------------------------------------------------

corporate purposes, except for certain legal expenditures which require
additional approval from Weichai. The Third Shareholder's Loan Agreement expires
on November 30, 2022 with any outstanding principal and accrued interest due
upon maturity. As of March 31, 2022, the Company had $40.0 million outstanding
under the Third Shareholder's Loan Agreement.

On April 20, 2022, the Company entered into an additional shareholder's loan
agreement with Weichai (the "Fourth Shareholder's Loan Agreement"). The Fourth
Shareholder's Loan Agreement, which matures on March 31, 2023, provides the
Company with access to up to $30.0 million of credit at the discretion of
Weichai to supplement the Company's working capital. The Fourth Shareholder's
Loan Agreement is subordinated in all respects to the Second Amended and
Restated Credit Agreement. Borrowings under the Amended First Shareholder's Loan
Agreement, the Amended Second Shareholder's Loan Agreement and the Fourth
Shareholder's Loan Agreement will incur interest at the applicable SOFR, plus
4.65% per annum. Further, if the applicable term SOFR is negative, the interest
rate per annum shall be deemed as 4.65% per annum. If the interest rate for any
loan is lower than Weichai's borrowing cost, the interest rate for such loan
shall be equal to Weichai's borrowing cost plus 1%.

As of March 31, 2022, the Company's total outstanding debt obligations under the
Second Amended and Restated Credit Agreement, the Amended Second Shareholder's
Loan Agreement, the Third Shareholder's Loan Agreement and for finance leases
and other debt were $195.8 million in the aggregate, and its cash and cash
equivalents were $2.3 million. See Item 1. Financial Statements and
Supplementary Data, Note 6. Debt, for additional information.

As of March 31, 2022, Accounts Payable were approximately $82.6 million reflective of elevated inventory, costs incurred related to the Company's indemnification obligations and the management of timing of payables.



Significant uncertainties exist about the Company's ability to refinance,
extend, or repay its outstanding indebtedness under its existing debt
arrangements, maintain sufficient liquidity to fund its business activities, and
maintain compliance with the covenants and other requirements under the Second
Amended and Restated Credit Agreement or shareholder's loan agreements in the
future. Without additional financing, the Company anticipates that it will not
have sufficient cash and cash equivalents to repay the outstanding indebtedness
under the Company's existing debt arrangements as they become due. Management
currently plans to seek an extension and/or replacement of its existing debt
arrangements or seek additional liquidity from its current or other lenders
before the maturity dates in 2022 and 2023 as discussed above. There can be no
assurance that the Company will be able to successfully complete a refinancing
on acceptable terms or repay this outstanding indebtedness when required or if
at all.

During 2020 and 2021, as a result of the COVID-19 pandemic, the global economy
experienced substantial turmoil, which led to challenging market conditions
across certain areas of the Company's business. In addition, due to
unprecedented decreases in demand, an oil price war, and economic uncertainty
resulting from the COVID-19 pandemic, average crude oil prices were considerably
lower in 2020 as compared to prices at the end of 2019 but showed signs of
improvement in 2021 and through the first quarter of 2022. However, although rig
counts in the U.S. oil markets increased during 2021 and through the first
quarter of 2022, average rig counts remained below pre-pandemic levels. The
Company also believes that capital spending within the U.S. oil and gas industry
remains well below pre-pandemic levels. While the Company saw an increase of
sales to customers with traditional exposure to the oil and gas markets during
the first quarter of 2022, as compared to the prior year, sales remain below
2019 levels. A significant portion of the Company's sales and profitability has
historically been derived from the sale of products that are used within the oil
and gas industry. In addition, the Company continued to experience delays in its
supply chain during the first quarter of 2022 due to temporary shortages of raw
materials and container delays of overseas materials as bottlenecks occurred at
ports in Asia and North America. This, in turn, caused delivery delays to some
of the Company's customers. The Company also experienced inflationary cost
pressures for certain materials and shipping-related costs. Additionally, the
Company continues to experience ongoing tariff costs for products that did not
receive exclusions. The Company is working to mitigate the impact of these
matters through price increases and other measures, such as seeking certain
tariff exclusions, where possible. The potential for continued disruptions,
economic uncertainty, and unfavorable oil and gas market dynamics may have a
material adverse impact on the timing of delivery of customer orders and the
levels of future customer orders.

Lastly, during 2021, the Company incurred significantly higher legal costs due
to its obligation to indemnify certain former officers and employees as a result
of exhaustion of its directors and officers insurance during the early part of
2020. In particular, spending activity was elevated during the first nine months
of 2021 as a result of the USAO trial involving former officers and employees of
the Company. With a verdict reached in the USAO trial matter involving former
officers and employees in September 2021, the Company believes its costs related
to the matter will cease. Accordingly, the Company saw a substantial decline in
these costs during the first quarter of 2022. However, at this time, the Company
is not able to estimate the potential future amount of its indemnity obligations
related to the pending SEC matter involving prior officers and employees. See
Item 1. Financial Statements and Supplementary Data, Note 9. Commitments and
Contingencies for further discussion of the Company's indemnification
obligations. Accordingly, the above challenges may continue to have a material
adverse impact on the Company's future results of operations, financial
position, and liquidity.

                                       32

--------------------------------------------------------------------------------

Due to uncertainties surrounding the Company's future ability to refinance,
extend, or repay its outstanding indebtedness under its existing debt
arrangements, maintain sufficient liquidity to fund its business activities, and
maintain compliance with the covenants and other requirements under the Second
Amended and Restated Credit Agreement or shareholder's loan agreements in the
future, substantial doubt exists as to its ability to continue as a going
concern within one year after the date that these financial statements are
issued. If the Company does not have sufficient liquidity to fund its business
activities, it may be forced to limit its business activities or be unable to
continue as a going concern, which would have a material adverse effect on its
results of operations and financial condition.

At March 31, 2022, the Company had five outstanding letters of credit totaling
$2.1 million. See Item 1. Financial Statements and Supplementary Data, Note 9.
Commitments and Contingencies for additional information related to the
Company's off-balance sheet arrangements and the outstanding letters of credit.

Critical Accounting Policies and Estimates



The Company's consolidated financial statements are prepared in accordance with
U.S GAAP. Preparation of these financial statements requires the Company to make
estimates, assumptions and judgments that affect the reported amounts of assets,
liabilities, revenue and expenses, and related disclosure of contingent assets
and liabilities. The Company's most critical accounting policies and estimates
are those most important to the portrayal of its financial condition and results
of operations and which require the Company to make its most difficult and
subjective judgments, often as a result of the need to make estimates regarding

estimates and assumptions are reasonable, they are based on information
available when they are made and, therefore, may differ from estimates made

The Company's significant accounting policies are consistent with those
discussed in Note 1. Summary of Significant Accounting Policies and Other
