auctions for these securities. If these auctions continue to fail, it could result in our holding securities beyond their next scheduled auction reset dates and will limit the short-term liquidity of these investments. We currently believe these securities are not significantly impaired, primarily due to the collateral underlying these securities and/or the creditworthiness of the issuer. The amount of the recognized loss was based on a valuation by our securities brokerage firm.
Interest Expense
Interest expense was $7,704 for the nine months ended March 31, 2007 and $17,854 for the nine months ended March 31, 2008. The 2007 interest expense is primarily attributable to the interest paid on the note payable to the former owner of Pools Press, which we issued at the time of the purchase of our majority interest on February 28, 2007 and paid in full on February 28, 2008. The increase in 2008 was primarily attributable to our use of a credit line secured by marketable securities.
Interest Income
Interest income was $49,844 for the nine months ended March 31, 2007 and $90,569 for the nine months ended March 31, 2008. This interest income is primarily attributable to the interest earned on investments in marketable securities and has decreased as we have liquidated these securities for working capital purposes. The investments were initially made in December 2006 so the 2007 amount includes only three months of interest.
Net Loss
We recorded a net loss of $223,505 for the nine months ended March 31, 2007 compared to a net loss of $290,639 in the 2008 period. We feel we have been able to contain these losses while building a company and funding the expenses necessary to become a publicly traded company. We hope to be modestly profitable in the near future, but as we are still a new business, we do not expect profits to be significant for the next year.
Liquidity and Capital Resources
As of March 31, 2008, we had cash and cash equivalents of $1,589,893, compared to $382,587 as of June 30, 2007. This increase is primarily attributable to sales of short term investments and advances on a credit line secured by our short term investments. Our short term investments decreased from $2,589,410 at June 30, 2007 to $1,705,894 at March 31, 2008, due to our liquidation of some of these securities for working capital purposes.
Net cash used by operating activities was $287,022 for the nine months ended March 31, 2008 compared to cash used by operating activities of $293,216 for the nine months ended March 31, 2007. During the 2007 period, our accounts receivable increased by $491,573 and our accounts payable increased by $394,532, compared to increases of $1,011,888 and $408,640, respectively, in the 2008 period. Additionally, we expensed $219,083 depreciation and amortization, offset by our use of $192,671 of prepaid royalties. Stock options with a value of $86,113 vested and we amortized $6,472 for stock options vesting in December 2008 during the nine months ended March 31, 2008. No stock options vested in the 2007 period.
Net cash used by investing activities was $3,938,789 for the nine months ended March 31, 2007 compared to net cash provided by investing activities of $393,917 for the nine months ended March 31, 2008. This difference was primarily due to purchases of short term investments of $3,340,206 in the 2007 period.
Net cash provided by financing activities was $1,100,411 for the nine months ended March 31, 2008 compared to net cash provided by financing activities of $4,409,559 for the corresponding period in 2007. The cash provided by financing activities for the 2007 period was primarily made up of $4,221,784 from our offering of common shares and warrants. In the 2008 period, the cash was primarily provided by advances under a credit line secured by short term investments.
We believe that our current cash resources will be sufficient to sustain our current operations for at least one year. While we have not experienced any losses from bad debts, our account receivables continue to increase as a result of significant increases in our sales. We also expect to incur significant investor relations expenses in conjunction with the listing of our common stock. In addition, we may need to obtain additional cash resources during the next year in order to acquire complementary businesses. The need for cash to
