11.  Commitments and Contingencies

Letters of Credit

We had a total of $3.9 million and $4.1 million in letters of credit outstanding in favor of certain landlords for office space and for credit line facilities as of April 30, 2021 and January 31, 2021, respectively. These letters of credit renew annually and expire on various dates through fiscal year 2022.

Indemnification

In the ordinary course of business, we may provide indemnification of varying scope and terms to customers, vendors, investors, directors, and officers with respect to certain matters, including, but not limited to, losses arising out of our breach of such agreements, services to be provided by us, or from intellectual property infringement claims made by third parties.

These indemnification provisions may survive termination of the underlying agreement and the maximum potential amount of future payments we could be required to make under these indemnification provisions may not be subject to maximum loss clauses. The maximum potential amount of future payments we could be required to make under these indemnification provisions is indeterminable. As of April 30, 2021 and January 31, 2021, we have not accrued a liability for these indemnification arrangements because the likelihood of incurring a payment obligation, if any, in connection with these indemnification arrangements was remote.

Defined Contribution Plans

We sponsor defined contribution plans for qualifying employees, including a 401(k) plan in the United States to which we make matching contributions of 50% of participating employee contributions. Our total matching contribution to the 401(k) Plan for the three months ended April 30, 2021 and 2020 was $3.1 million and $1.9 million, respectively.

Litigation

From time to time, we may be involved in lawsuits, claims, investigations, and proceedings, consisting of intellectual property, commercial, employment, and other matters, which arise in the ordinary course of business. In accordance with ASC 450, Contingencies, we make a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

We are not presently a party to any litigation the outcome of which, we believe, if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, cash flows or financial condition. We have determined that the existence of a material loss is neither probable nor reasonably possible.

Warranty

We warrant to customers that our platform will operate substantially in accordance with its specifications. Historically, no significant costs have been incurred related to product warranties and the probability of incurring such costs in the future is deemed remote. As such, no accruals for product warranty costs have been made.

Other Commitments

Certain executives’ employment agreements contain provisions providing for severance upon termination.

Due to the growth in the fair value of our common stock combined with the timing between when certain employees began employment with us and the date that their stock options were granted, the actual exercise price of the grants made to certain employees was higher than the price in effect at the time of their hire. In order to compensate the individuals for the increased exercise price, we have granted long-term incentive awards consisting of cash payments equal to the difference between the exercise price in effect at the hire date of these employees and the actual granted exercise price multiplied by the number of shares of common stock subject to the stock options granted. We have recorded $0.9 million and $0.9 million within accrued expenses and other current liabilities in the condensed consolidated balance sheets and have additional unrecorded commitments to these employees of $2.9 million and $3.4 million as of April 30, 2021 and January 31, 2021, respectively.

Non-Cancelable Purchase Obligations

In the normal course of business, we enter into non-cancelable purchase commitments with various parties mainly for hosting services and software products and services. As of April 30, 2021, we had outstanding non-cancelable purchase obligations with a term of 12 months or longer as follows (in thousands):
