Our capital sources are focused on investments in our technology solutions, corporate infrastructure and strategic acquisitions to further expand into new business sectors and/or expand sales in existing sectors. The company generates sufficient cash flows for working capital and expects to do so for the foreseeable future.
For the six months ended June 30, 2020 and the six months ended June 30, 2019, our Unlevered Free Cash Flow conversion rate was 80% and 90% respectively. The decline is due to our increase in non-recurring investment in capital expenditure as a result of the consolidation of our software development platforms. We are also internally developing our data messaging platform in order to enhance our messaging revenues.
We use our cash primarily to make payments to our distribution partners and internal staff as well as to make payments for general operating expenses and interest expense.
Our principal sources of liquidity on a short-term basis are cash and cash equivalents, and cash flows provided by operations. During the six months ended June 30, 2020, we increased the capacity on our revolving commitment and borrowed the remaining availability as a precautionary measure to reinforce our cash position and preserve financial flexibility in light of the current uncertainty in the global economy resulting from the COVID-19 pandemic.
On July 15, 2020, DMS completed its previously announced business combination agreement with Leo Holdings Corp. (NYSE: LHC) (“Leo”), a publicly traded special purpose acquisition company.
Immediately following the closing of the transaction (the “Business Combination”), Leo changed its name to Digital Media Solutions, Inc. (“New DMS”). The current DMS executive management team now leads New DMS, which trades on the New York Stock Exchange.
This business combination raised an amount of $40,000 in cash for the Company, $10,000 of which is used to pay down debt.
Cash flows from operating activities
Net cash provided by operating activities increased for the six months ended June 30, 2020 as compared to the six months ended June 30, 2019 from $1,038 to $3,693, due primarily to changes in our working capital and adjustments for non-cash items.
Prepaid expenses and other current assets increased by 237% in Q2 2020 as compared to Q2 2019 as a result of transaction related expenses incurred in relation to the business combination agreement with Leo. Depreciation and amortization expense also more than doubled between Q2 2019 and Q2 2020, as a result of assets assumed from acquisitions and internally developed software placed in service.
Net income also saw a significant increase of 484%, which contributed to the increase in net cash provided by operating activities for the six months ended June 30, 2020 as compared to the six months ended June 30, 2019.
Cash flows from investing activities
Net cash used in investing activities for the six months ended June 30, 2020 increased by $2,287, or 83% to $5,031 from $2,744 for the six months ended June 30, 2019 primarily due to increased investments in internally developed software. Between the six months ended June 30, 2019 and the six months ended June 30, 2019, internally developed software increased by $6,101, or 136% from $4,476 to $10,577.
Cash flows from financing activities
Net cash provided by financing activities for the six months ended June 30, 2020 was $6,281, reflecting an increase of $8,170, or 433%, as compared to net cash used in financing activities of $1,889 for the six months ended June 30, 2019. This increase was mainly due to the increased borrowing on our revolving line of credit of $9,000 during the first half of 2020, offset by quarterly repayments of long-term debt.
